E71 Battery Life gone

My E71 battery life has gone off a cliff. One day it was lasting 2-3 days with constant use. Next it's lasting less than one day. It's 6 month old. Anyone got any idea why ?
I haven't changed my use, nothing is running in the background except bluetooth for my headset. I have not updated the software. Even tried running battery flat a couple of times and recharding.
Any help or ideas apperciated as it's very frustrating. Main reason I bough E71 was battery life after the appaling battery life for E66.

How many cycles do you think the battery has performed?
Around 200-300 Cycles is probably good.
They don't last forever, contrary to what some people believe.
If you have switched off stuff like WLAN Bluetooth and 3G and the battery is not lasting very long then I would consider getting a new battery.
They are pretty reasonable, around GBP £20, €30 approx depending where you are.
Rapid decline in battery charge hold is indicative of a failing battery.
Additionally if the handset is getting hot, then you should get it looked at, at a Nokia care point without delay.
Shunts...
I will mostly be communicating with a Nokia E72 Zodium Black
Nokia E72-1 with Vr 051.018.207.04 Software
If this post helped... Add some kudos!!

After updated firmware of E71 /Battery life is poo...

After I updated the firmware of my E71 to 200.21.118 version, my phone lack of battery life, I think the problem is mail for exchange version 2.09.158 that have conflicts with the new firmware. After the updated, my phone is always hot and my battery is no longer than 12 hours of use (before at my use 36 hours), I turn the mfe to manual and fix the problem.
Can any body helpme with my problem?.
Regards,

have you performed the three-finger hard reset after upgrading to the latest firmware version? this is often the source of problms, as giving the phone a clean slate to work with will most likely solve these battery issues. remember to backup all your data first to memory card and to computer using Nokia PC Suite as a .nbu file. after hard reset, restore everything back to your phone using the .nbu file. to perform a hard reset, turn the phone off then press the green call key, the 3 key and the * key all at the same time, then press and hold the power button.
If you found this or someone's comments helpful or like what that person has to say, please give some Kudos to their post!

Battery life gone after "upgrading" to 4.3 (iPhone 3GS)

I've lost all battery life after upgrading last night to ios 4.3! I barely get 5-6 hours, whereas I always got a full day (probably two if i let it run down) before the upgrade. I can't believe this is a coincidence. How do I go back to 4.2? Or is there a cure for this?

OK, problem solved, with the help of Apple Support.
They suggested that I re-install the upgrade using Restore on iTunes. So I backed-up the iPhone, did a Restore to factory settings, and then restored all the apps, music etc from the back-up. The phone was fully charged 8 hours ago now, and has gone down to 80% with some occasional use .... this is typical for my 3GS. So: "Restore to Factory Settings" worked. Don't ask me why!

E71 Battery life

hi,
how long are other E71 users getting on a full charge. With bluetooth, wifi off i am getting 6 hours max.
Thanks
Richard Kingsley

Richard may be correct about this. Check the heartbeat setting in the 'Schedule' tab of MfE. Ideally you should be at about 8-10 minutes. 1 is worst case.
If you are at 1 minute heartbeat, it is not the fault of MfE. It is important to pick an access point that allows long connections to the server without any activity. What could be happening is that your provider is disconnecting MfE because it doesn't appear to be doing anything. Then MfE wants to reconnect to maintain Always on. This uses lots of battery.
You may need to change your AP or pay more for better plan that allows these type of connections.
Otherwise, change to hourly or Manual sync.
I get 30 minute heartbeat with AT&T in the US. If I don't make any phone calls and keep an 8-5 Always on schedule, I can get 4 day battery life.

E71 Battery Life (Compare with E61, E61i)

Most of the E71 newbies claim that the battery life is awesome. But for me, the E61i, and E61 user, I discovered that the battery life in E71 seems not as good as the one in E61.
Typically, under my usage (Daily 5-10mins short calls x 10, every 15mins pull mail from pop, ~50mails daily, lowest brightness, no wifi, no bluetooth, no 3G, no mp3, no DC),
the E61 last for 3 days or more, but E71 is hardly to last for 3 days.
Checked with Nokia Profiler, the consumption during a conversation is throttling between 0.6 to 0.8, avg 0.75W
sometime near 1W max. For 3G conversation, the power consumpted is almost doubled.
It implies the phone is consumping 250mA ideally.
1500 / 250 = 6 hours
1500 / 500 = 3 hours
Far away from the official value from Nokia.
Anyone share your experience ?

Is my battery life gone? R.I.P

I have used my ibook G4 for 1year and 3 month already, but now the battery suddenly showing some strange loss of its battery life, it takes only around 50 minutes for full charge, and after that only around 45 minute i can use before it drains out,
usually when the battery drains out, my ibook will go to sleep mode and it will maintain the sleep mode as long as i want it to be, but now what suprise me, when the battery drains out, it will suddenly turn off my computer instead going to sleep mode, it have happen twice now, so thats what makes me very worried, im so frustrated because i take care the battery so well but it suddenly become like this, not in a degrading fashion, its all in a sudden...since 2 days ago...
first question of all, is my battery life altered? or my battery already dying? what should i do? change to new battery? the new battery is so expensive...
2nd question, will my computer be damaged if it suddenly turn off like that without shutting it down properly?
hope somebody can help me on this

Welcome to Discussions!
Yes, if your iBook is not going in to "sleep mode", and abruptly turning off, it can cause damage over time. You said that is "fully charged" after 50min. Try leaving it plugged in for a full 24 hours, and see if that extends battery life at all.
Question? Are you running any processer intensive applications when its on the battery? Anything such as an audio/video application, anything with mathmatiacal equations, playing games, using the CD ROM drive, ect... All of those factors can shorten battery life. When the iBook runs out of power, it should automatically go to sleep, and remain in sleep for a day or two before finally shutting off.
Try resetting the PMU (Power Management Unit) ((taken from the Apple Support website))
1. If the computer is on, turn it off.
Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
Wait 5 seconds.
Press the Power button to restart the iBook computer.
Reset the PRAM:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Reset the NVRAM:
1. Turn on your iBook
2. Before the grey screen, press command-option-O (letter)-F
((O is for "open", and F is for "firmware"))
3. You will be at a grey screen displaying some information.
4. At the Prompt, type "reset-nvram" press return.
5. Type "reset-all" press return
6. Type "mac-boot" press return
I hope this helps!

I have tried to upgrade my iPod touch , and cant even remember to which iOS , and it didnt respond with the upgrade and does the loading logo until the battery life is gone. I tried restarting it doesnt work. NEED HELP

I have upgraded my iPod touch and it didnt respond to the upgrade. Cant remember which iOS i was upgrading but when i try to switch it on the apple logo comes up but than it just goes to the loading logo until the battery life is gone. I have tried restarting it , that doesnt work. I need help i am lost without my ipod please help. Any ideas besides restarting it ?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT6154 After updating to IOS 7.1 my battery life has gone bezerk.

After updating to IOS 7.1 my battery life has gone bezerk. I just finished a 6 minute call with my bank and the battery life went from 93%-23%???? Then i pkugged it into the charger and the battery insicator went right to 48%. Found this article and followed it to the T to no avail.:
Guide to Solving iOS Battery Drain http://iClarified.com/39722
Please I cannot think of a better phone to use, and this is where apple will make or break me.

Please be more specific. What have you tried already? Please follow the below steps as described also in another topic by Nathan.
1. Hard reset hold both buttons until Apple logo appears.
2. Restore from an iTunes sync and backup. This made a difference for a lot of peopel, battery life got much better.
3. Limit push notifications (apps and e-mail accounts - set e.g. e-mail to fetch once an hour) to those you really need.
4. Limit location services to those you really need, and watch to see if the indicator comes up.
5. Get the app System Activity Monitor to look for a runaway process that is using a lot of CPU.
6. Suggestion by others to reset all settings.
7. Suggestion by others that iCloud may be involved, and to try to turn off some iCloud settings.
8. Limit or turn off 'background app refresh'.
9. Add apps back in carefully to identify an offending app that is causing CPU or network activity that kills battery life.
10 Also make sure that e-mail is fetched (e.g. every hour) or set to manual instead of pushed.
11 Do you have a good carrier reception? Have you tried to manual set your carrier within your iPhone instead of the 'automatic'?
12 Have you checked if the timezone is set to manual instead of automatic and see if this makes a difference in battery use?
In my case it was a bug with an app that caused the battery drain. I also noticed that the use and stand-by time were exactly the same which is ofcourse not correct. This was all caused by this app which was using GPS tracking all the time. Unfortunately an app such as System Activity Monitor did not indicate that in my case but someone posted this solution on a Dutch forum that the previous version of the app 'Scoupy' had a bug and caused this battery drain.
If you haven't tried every single one of these, please do not post that battery life is terrible.

After upgrading my software to 6.1.3 I feel my battery life has gone down, anyone else have this?

My battery life has considerably gone down after I updated. I will task kill all apps turn brightness down, location services off and wifi off and 6 hours later of not using my iPad it will be down 25% (to 75%). Is this normal? Has anyone else noticed this? Or is this possibly related to something besides the update.

Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.
Use the wall-mount charger that came with the iPad and charge overnight. Admittedly the labeling is hard to read but, if you use a magnifier and squint your eyes, you'll see "Output 5.1V, 2.1A." The symbol between volts and amps is the symbol for DC. Do NOT use an iPhone charger. Do NOT use an iPod charger. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the exact procedure necessary to calibrate the battery level meter.
I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know whether or not a battery problem exists.
According to Apple:
Use Your iPad Regularly
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

My macbook pro will not hold life even though plugged in - I know battery life is about gone; does that mean it won't stay alive even though plugged in?

My macbook pro will not hold life even though it is plugged in when I use it. I know the battery life is about gone, but didn't realize this effects it when plugged in or does it. It is about 7 years old. This is second battery. Am I right to think this?

You are right - a dead battery can some times play these kinds of tricks.
If this is a removable battery, I suggest you take out the battery and try running it on the power adpater alone.

After playing 60-70 songs on shuffle battery life is almost all gone.

Well the subject says everything...
Basically after I play 60-70 songs on shuffle, the battery life is almost gone. (After being fully charged) I don`t know if this is part of the reason why it only plays that many songs, but I do turn my ipod on an off a few times. (About 4-5 times?) But I don`t think that`s a good enough reason for the battery to be so low after playing only about 3-4 hours. I don`t have any songs that go over 5 minutes and I don`t watch videos or put on the slideshow while playing music. And the only times I touch the click wheel is when I want to raise/lower the volume or skip to the next song. So I don`t know why it only plays for such a short time. Does anybody know why it`s doing that? And is there any way I can fix this?
Windows XP

Try just letting your ipod play one song over and over, and see how long it lasts. If it still has the same problem, get the battery replaced.

Updated my 3gs to 5.0.1 and my battery life has gone from 1.5 days to less than half a day with no Apps open - how can I roll this back to 5.0 until a fix comes out?

Since updating my 3GS to 5.0.1 my iphone battery has gone, overnight, from 1.5 days + (with multiple open Apps) to less than half a day to completely discharge from 100%.
I desperately need to roll this install back to 5.0 but there are no resources on the internet (or this site) which indicate how I would do that.
Please help.

You cannot and should not go back to 5.0.
A fix is coming soon

Any fix to the battery life issue from upgrading to IOS 6.0.2, as my battery life has gone from 2 days to 4 hours since 'upgrading'??

I purchased my Iphone 5 on the day of release, since then I have had a 2 day battery life on average, since upgrading to IOS 6.0.2, the battery struggles to last for 4 hours, is there any solution or fix?? If not any idea when this will be fixed?? Is there anyway to revert back to IOS 6.0.1?
HELP!!!

It is unlikely that this problem has anything to do with iOS 6.0.2. It is possible that the update process itself has caused some settings on your iPhone to become corrupted.
Here are some steps to deal with this:
1. Close all apps (use the app switcher; double tap home, press and hold an icon, click the "-" signs)
2. Go to Settings -> General -> Reset -> Reset All Settings. (Does NOT delete apps or any data; just resets network/iOS settings)
3. Wait for iPhone to restart.
4. Charge iPhone up to 100% and monitor.

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:

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

Macbook Air Poor Battery Life

I have a mid-2012 Macbook air and I've noticed recently my battery life is horrible. I've read every single other thread about this issue but nothing really helped and even the most recent is from a couple of years ago. Obviously now it's 2015 and my macbook is running on Yosemite, so its not the battery issue that everyone seemed to have with Mavericks.
Just writing that small section I went from 73% to 68% and at the current 68% I only get an estimated 2 hours and 10 minutes remaining. I've also had only Safari running this whole time.
Option clicking the battery icon reveals that the condition is normal, as well as the power system report. It also has gone through only 441 cycles, no where near its 1000 cycle "limit" and its health is already down to 77%. While obviously the condition is normal and doesn't say I need to replace the battery I feel that I should, based off of everything else.

Have macbook air from mid 2012 - I installed Yosemite November 2014 and since then I'm having problem with my battery - it has been draining super fast - 4hrs battery life now compared to earlier 8hrs.
I reinstalled Yosemite, didn’t help and then made a clean reinstallation of Yosemite about 5 days ago and there is still the same drain issue.
Thank you in advance!
