N95 battery life

Hi all
just got my nice shiney new N95 and i love it. Dose every thing it says on the tin (well almost but im sure its user issues).
However there is one issue that is driving me mad, and it s a big problem. The battery life, i can best describe it as **bleep**.
On average it will last about 12 hours with almost no use and at worst it goes flat leaving me high and dry in about 3-4 hours of use.
I have W LAN search off and its mainly on factory settings but in struggling to get more life out of it.
Are there any settings or better batterys that i can use. Its a big enough problem to make me hand the phone back to my phone supplier as its not fit for purpose.
Ta Wavey..
grrrr gagged again

5. Check that in the Packet Data settings the 'Packet Data Connection' option has been changed to 'When Needed' this mode will only use packet data when needed from your operator.
Regarding pt 5 i am using 3G aus, and have checked the option to what you have said, but my phone will never stop searching for packet data connection? what might be the reason?
it also has an option to enable or disable 'High Speed Data Connection' what is this? will disabling it lead to me not being able to check my emails?
Kindly advice as i have to use 2 batteries to keep the phone alive for the whole day i am getting sick of it.

N95 Battery life possible solution to poor battery...

Hi all
I like most other N95 users have experienced poor battery life, to the point of almost giving up on it.
I had been consistantly getting poor life even down to a couple of hours with all power hungry devices turned off.
Now my phone, with what I would consider average use, lasts up to 2 days on a full charge.
Like most people, I guess, I took it straight out of the box and plugged it in the wall charger and left it over night. I did this for the first week with still poor battery life.
Then one day it just started holding charge for up to 2 days.
I decided to read the manual the other night about charging the battery and right at the back of the book, where the instructions are, it mentions that if the battery has not been used for a while or has been in prolonged storage that what you should do is plug the charger in the wall and phone, switch on the charger and this is the key...unplug the charger from the phone and plug back in again. I guess this puts the battery into a discharge/recharge cycle.
If like me, you just plugged it straight into the phone and switched on the charger and left over night it may only have just topped up the battery without doing the discharge cycle first. In effect creating a battery memory effect although I thought that was a thing of the past.
Worth a shot before giving up on you N95's!
Like I said I now get on average 2 days use and that is with calls, pictures, texts and about 2 hours of GPS use a day.
I still have Wi-Fi scanning off and GSM turned off, I havn't got round to trying it with these functions turned back on.
Good luck!

WHAT??!? 200 hours on standby??
The truth, is this phone was made to be constantly plugged into car handsfree kit (not bluetooth) so that its constantly on charge. Bit like how a car GPS navigation unit, although removable, is constanly on charge while you are in the car driving.
Hence why the compromise- big power hungry screen and applications and hardware, low battery, but ok as constantly on charge.
Nokia Do NOT have a car kit for the N95 beleive me I have tried
I have been in touch with Nokia several times
The best I could do is a brodit active holder for car use
Yes The N95 should have a car kit but it does not have the pop port so will only connect on BT using even more battery power
So thats not the reason for the poor battery
Mine sometimes can last 10 to 15 hours and other days goes flat in under 3 and it is charged every night (it has to be) My N73 lasted 3 days and my 6230 last 2 weeks
Nokia user / modder since Nokia Orange and Mobira user too before that

N95 v20 Battery life

Ok so it seems that the v20 firmware for the n95 is susposed to improve battery life! Well .. . thats aload of rubbish!! I have just updated to v20 from v11 r12 and it now seems my battery lasts about 7 hours max! when i had version 11 or 12 it lasted about 3 days! Anyone having the same problem?

I dont see any improvement on the battery life of my N95-2 with the new fw. Usually it lasts for 2-2.5 days.

N95 vs N93i vs N80i for battery life

Hi, I am buying a new phone and I really like the N80i [N80 Internet Edition] but I hear that it doesn't have very good battery life (less than 1 day). So I am also looking at the N93i and the N95. I know that they provide more features too over the N80i but I'm not so interested in those, I just want to know about the battery life. How do these three compare for battery life? (I know that the N93 standard edition seems to have better battery life than the N93i, but I can't seem to find anywhere to buy this one in my country).

Hi,
If you're not after with the features....why don't get Series 40 phones like 6233, 6280 and 6288? Which has a good battery life and much responsive compared to symbian phones.
We've tested the N6233..and it manage to hold its charge for almost 3 days with heavy usage.
Ouch! Only series 40 phones are symbian? S60 series phones(like the N series) are not, are you misqouted?
Knowledge not shared is knowledge wasted!
If you find it helpfull, it's not hard to click the STAR..

N95 Updated software causing Battery life issues

Hi
Can anyone help point me in the right direction?
I Updated my software on my N95 (silver) to V13.0.003 but since doing so the battery life has suffered,it hardly lasts half a day just on standby, where as before I'd get 2 days at least. Bluetooth is turned off Wlan searching is off there is nothing running except Standby mode.
I've also tried a different battery, and get the same results.
Any ideas?

N95 Silver, I guess is the N95-1 or 3, both have newer firmware versions.
For N95-1 (RM-159) the last version is 30.0.015 and for the N95-3 is the 20.0.something. Both versions improves a lot the battery life and speed of the devices.
Check your last version with Nokia Software Updater.
Don't forget to make a backup of all your data before updating.
Remember that not all versions are available for all the product codes.
Cheers!

Latest firmware will depend on your operator branding; unbranded I think has the latest release of v31?
I believe that later versions have improved battery life through better handling of the comms systems, better use of WiFi, etc.
I'm getting up to a couple of days out of mine, keeping it to 2G (unless I need a big download fast), WiFi scanning off, screen backlight turned down, timeout set relatively low, etc.
But if I hammer it, a bit of music/gaming/WiFi/calls and its dead within a day.
You can buy higher capacity batteries, but I doubt they're recommended, as they require a new back (ie. bigger phone) or just won't be as reliable as the original Nokia kit.

How to increase the battery life of your N series ...

What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
Hope this helps.

no keffa it is a cop out from nokia
its not unfai as its a premium device with a premium price
the n95 battery is atrocious
dont change the post content as the title is 'How to increase the battery life of your N series device'
your talking about nokia phones specifically
the networks are not to blame
they do not make the handsets : Nokia do !!!!!!!!!!
I'm going to choose my words carefully here...
I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

N95 battery

hiya thought id let you know how long i get out of this battery in the n95
fully charged at 9am
made 1 hour 10 mins of calls via bluetooth
listened to 1.5 hours music via bluetooth
sent 8 txts
no wifi and it is switched off completley
iam using 3g network
by 2pm i had 3 bars of battery an was scared to listen to more music as i dont finish wrk till 5
my n73 would have all its bars left and thats with music all day
iam looking on ebay ive seen a battery for 8 pounds its 1200mah in size
thats 100mah bigger then the n73 battery surely this will work better and last longer??
has any1 tryed a bigger battery at all??
what were the results??
i love my n95 but at the moment iam leaning back to the trusty n73 as the battery is awesome
i had the n80 for 1 week before i sold it cus of the battery the n95s seems just as poor
i cant understand how nokia bring a device out with grounbreaking features but put a smaller battery in it then a device with less features!!!!!!
nokia must have had loads of complaints about the n80 but still they realease the n95 with a battery which isnt adequite
any feedback appreciated guys
by the way i turnt backlight to 10 secs standby mode cums on after 25 seconds and i even turnt the screen brightness down a notch!!!!
thanks

nah mate no apps open, how can you be impressed with what i done on the phone?? by the time id finished work at 5pm i was nearly empty 1-2 bar max that was with medium use as i noticed it was going down quick and didnt wanna be without my phone for the rest of the day.my n73 would have had 4-5 bars after the same use and more
had symbian phone since the 6630 all the way through 6680 n70 n73 n80 n95 so pretty good with them and power saving features and ways to make them quicker etc
ive decided to sell my bluetooth headset that i used with my n73 cus the battery was sooo good
go back to the wired headset as bluetooth connection is defently going to drain the n95s poor battery
ive turnt the backlight down to minimum
turnt backlight time to 10 seconds
turt power save mode on after 20 seconds
warning tones off
ringtone half way
all apps and games saved to phone apart from emulators so memory card isnt allways being accessed and read etc
ive bought a second battery to use as a spare
a desktop charger to charge the battery and phone over night
left a charger at work just incase
:-0 oh my god the things ive had to do to try to extend my battery life!! :-0
i think nokia should hurry up and release a new battery for the n95 personally evry n95 owner would buy one 100%
i spose they are happy with selling every1 a second bl5f battery though
next thing ill be buying chagers to leave round my mates houses just in case or a wind up charger just incase :-)
i know its easy to plug it into a wall etc but i just think a phone that has a retail price of 500+ pounds or however much they charge should be able to take a days heavy usage i hadnt even taken a snap or a video god forbid what that does to the battery and this was designed to be used as a 5mp camera
iam sure 5mp cameras would have bigger batterys in iam not sure but they must be bigger then 950mah
iam wondering if its summing to do with the nokia wifi phones the n80 was terrible with the battery and so is the n95
any other wifi nokia phones that have poor battery life??
i was thinking maybe wifi is somhow draining the battery even though we see it as off in the settings etc??
i know its a long shot but ive never noticed bad batterys apart from the n80 and n95
thanks for your replys guys
peace out and have a good 1
lol you might see my n95 on ebay soon still got the n73 and that battery is soooooooooo good compared to this one. you can actually use the phone without having to have backup chargers stashed everywhere :-)its great :-)
only major differences is slight menu changes ie few new apps due to wifi etc --the cameras even though with the n73s if you use the settings you can get such good pics roughly 1.4-1.8 mb in size with lots of details the n95s is better but not by loads and loads :-)
and wifi but hey i dont use that anyway , maybe its just cus it kills my battery and iam scared to use it :-) incase i run out of juice when i need the phone to ring someone :-)
saying that the n73 is smaller and feels a bit sturdyer due to it not being a slider :-)
still unconvinced on this n95 dont get me wrong loving the features just get me as much juice as the n73 which is how much older then the n95?? gota be 12--18 months hasnt it?? and id be soooo happy
i dont think you can call this the perfect device yet as a perfect device would have a much better battery and i know nokia prob never release a perfect device as what would they do next but for 500+ pounds rrp youd expect it to pretty dam perfect wouldnt you :-)
just my 2 cents :-)
nice 1 have a good 1 every1Message Edited by buxz777 on 17-Aug-200708:37 PM

Possible Internet Tethering/Battery Life Issue

When either Cellular Data is turned Off, or Airplane Mode is turned On, Internet Tethering (Settings>General>Network) appears to have some process that runs continually in the background (evident by continuously spinning wheel next to the option). The running process has a demonstratively negative impact on battery life (1/3 reduction in ~ 30 mins). The Apple Genius at my local Apple Store and I verified the issue on numerous iPhone 4s that were on display. Turning Cellular Data On and ensuring the phone is not in Airplane Mode stops the activity. But obviously that defeats the purpose of having those options.
So if you are experiencing poor battery life, this might be your issue.

My new ipod touch's Battery life is extremely short

I bought 10 days ago the latest iPod touch and it is getting very poor battery life.
Even without using multitasking and with having notifications turned off, it is running from full to empty in less than two hours.
What is it that I have to do between all the things people recomend?
- Reset Network Settings
- set it up as a new device with no apps
- Powering off every night
- Shutting down Wi-fi all the time
- turning off push mail, notifications, etc
- Turning off "Location Services"
I've tried doing the lasts 4 things and nothing improved..
Or is it just because it's new and in the future it'll work longer?
Thanks you all for your useful answers!

Thank you and good luck!
General info and specs
First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
http://www.apple.com/batteries/iphone.html
http://www.apple.com/batteries/
... you didn't read it? loll Always remember this i.e. the definition of "usage":
Usage: Amount of time iPhone has been awake and in use since the last full charge. The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
Optimize your settings
Depending on how they are configured, a few features may decrease your iPhone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals. The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power. Go to Settings > General > Bluetooth and set Bluetooth to Off.
Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas. Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls. To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
Adjust brightness: Dimming the screen is another way to extend battery life. Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions. Go to Settings > Brightness and set Auto-Brightness to On.
Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life. To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact. Go to Settings > iPod > EQ and tap Flat.
Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
Standby time: Up to 200 hours (0.5% per hour drain)
Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
Video playback: Up to 10 hours (10% per hour drain)
Audio playback: Up to 40 hours (2.5% per hour drain)
So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
Apple's test methodology for claiming the specs:
http://www.apple.com/iphone/battery.html
Procedures
davidch tips (reset+full discharge recharge):
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (tilll it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the                 infrared is off after the reboot).
7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
* I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
buxbuster tips(wifi sync, iCloud):
These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
Workaround number 1. Deselect wifi-sync in iTunes and press sync.
If that doesn't work try :
Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
rolandomerida tips - i.e. buxbuster and additional steps:
Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
This is what I did:
1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
4.Turn Wi-Fi on.
5. Add the iCloud account again.
That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place

Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
As for 4S battery life. Try doing this,
1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
2. Settings>Notification>Calendar ... turn off the Notification Centre.
3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
Try these 3 steps first... if it still drains a lot, try the following,
4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ... tap backup to iCloud from your iPhone. It will take a while if the file is huge.
Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
Once it's all done restored. Turn off your iPhone,.. and turn it on again.
Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
Good luck. Let us know if it works for you.
W. Raider tips (Sirii):
Bottom line for me of things that helped battery life are:
1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
Hope this is helpful!

jmm514 remarks (Twitter):
I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
tmksnyder comments (notifications, corrupt data in iCloud):
For me, I found my iphone on wifi mysteriously connecting to my mac. I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud. The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x). Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone. It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification). I also found that iCloud control panel on OSX would error if I tried to delete the file. I fixed it by removing the App and doing a hard reset which stopped the sync. I probably could have turned off iCloud document sync in the phone but didn't think of that. My battery life has greatly improved while at home on wifi.    I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery. It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage. My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby. I was amazed.   Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event. I could drop my percentage by 5-10% in a matter of minutes when doing updates.   I think a lot of our problems are background processes, associated with iCloud, notification, and apps. More features means more battery.   I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden.   It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks that occur for the service on an os level not an app level. This minimizes the load so there arent a bunch of apps all runing and constantly checking. The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone. No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed. If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery. I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message. On nights I get no notifications, I see a 3 or 4 percent drop. On nights with a number of notifications, i have seen up to a 10 percent drop. Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain). For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info. I think it has a good overview of how the notifications work.

Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable.
Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent. If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)

The original solution still represents a high level of success for users having any battery issues.
Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
Make sure your device can run iOS 5.0.1 and is not altered.
Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
Reset the device doing a hard reset and software reset.
Let battery drain and then charge for the full cycle, which is 24 hours.
I think you will find you will get the battery usage that APPLE has stated for the device.
Best of luck, stay safe and thanks
