Interesting battery improvement discovery

After the v102 update last week, my phone was getting low usage and standby time. It was like 5 hours usage with 35 hours standby and only about 30% battery left; no wifi, no BT, no email auto-check except Yahoo push, auto bright on. I found a handful of tips about discharging and conditioning the battery and this is what I did. The following is based on a combination of different tips plus some of my own "six sense". The improvement of my battery has been very satisfactory.
1. run the battery down until it turns off
2. let it charge upto about 20%, remove it from the charger with the battery meter still red, turn it off and turn it back on, and the meter is now white 25% to 30%; turn it off and turn it on again, the battery meter is now 35%+. Something funny is happening here. Although the battery was only charged upto 20% (red) and removed from charger, subsequent multiple power off and power on somehow caused the battery meter reading to change. This could be an indication that the battery meter wasn't reading the phone's battary capacity correctly in the first place.
3. run the battery down beyond the 10% low battery warning, but before the auto shut off
4. put it on the charger, turn it off and let it charge for 8 hours
5. next morning remove the phone and left it off for 8 hours
6. turn it on and it shows it is 90% full with previous stat still intact
7. top it off on the charger and the stat resets
8. start using the phone
After I did the above steps, my current usage is 8 hours (2 hours phone calls, 5 hours music, 1 hour internet), on my fourth day of standy, with 30% battery left. I don't plan to do the above steps every single time I need to charge the phone. That would be too much trouble. I am only hoping that it can improve the accuracy of the battery meter so the phone can charge correctly; basically to avoid a premature "full" charge.

I have not had any experience with the specific battery in the iPhone but I have used a lot of lithium-ion batteries in other applications. I can tell you that those batteries I have use have had capacity improvements when new after several charge cycles.

Interesting Battery rehab Suggestion from a Genius Bar guy

I have a 2003-vintage PB17 a friend gave me when he upgraded. I believe the battery is original, and it shows 87% health and 106 cycles--not bad for an old machine. Still it shuts down at between 60 and 70 percent. If I start to charge it, its level grows slowly for a while and then jumps to 100 percent.
Normally I'm 350 miles from an Apple Store but on a recent trip to Portland OR, I packed the PB17 along for a visit to the Apple Store in Washington Square Mall. The genius confirmed that, based on serial number, the battery was probably original and that there were no warranty extensions or repair programs for 17" batteries.
However, based on the fact that the computer shuts down at about the same point each time, he suggested that one of several internal cells within the battery was failing to reset. He said I should let the battery run down and let it recharge to some point below the cut-off range (60-70 percent in my case), then run down the battery again and recharge.
I haven't had time to do this yet but thought I'd offer it for those with similar battery behavior.
Another tidbit of info he had was that the backup battery was rechargeable. I knew it was in the G3 PowerBooks but thought is was not in the G4s. I tend to agree with him; the first time the battery croaked, the computer had been off power for a long time and I got a total shutdown, The second time, after running a lot on A/C, the backup battery held function until I could get the PB back on wall power.

I would say untrue. Just my opinion though as I (and am sure that person) don't have access to the source code.
With that said, I have had the iPhone since Day 1 and have not had an issue with the battery or how it reads it's charge.
However, my wifes phone has on a couple of occasions not shown a full charge after being plugged in all night (to outlet, not computer thus sleep mode not an issue). A turn of and on did not correct it (as turning the phone off just puts it to sleep, it doesn't reboot the OS). But a reboot fixed it instantly.
Read this thread about the OS and reboots.

Battery Improvement!

I noticed that after the 5.0 update my battery doesn't get nowhere as warm as it used to when charging. I have my phone charging as i type, and it's laying on my bed.
In the past i had to charge my phone on a hard flat surface, such as the kitchen counter, nightstand, t.v. stand, etc.
Also, i don't know if this happened before and i just didn't notice it until today. The charger part that goes into the electrical socket immediately cools down once it reaches 100% charged.

Yeah, most come with a square block or attached ac cable-plack. These LG chargers are serious. They recharge everything faster. LG even included a turbo charger for my LG Volt. Usually, bigger the battery (3000mah on G2 and Volt) bigger the charging rate.

An interesting battery problem

I just recently bought a new battery. The first two weeks were good. I could charge it, everthing seemed normal with my computer. Then it stopped showing a charge, so it looked like my battery was empty and wouldn't charge. However, whenever I unplugged my computer it wouldn't die, it would actually last for more then two hours on the battery that appeared dead. Is there any way to fix this so my computer shows that the battery has a charge or am I stuck in the dark?

What exactly do you mean by it stopped showing a charge does the battery monitor on the control strip say the battery is dead?
You could try to reset the PMU.

Can I use Zen Nano firmware in my N200? Also battery cover replaceme

I was looking for a firmware update for my N200 and noticed it hadn't been updated since February. The N200 isn't even listed in the menu of products. The Nano and Nano Plus were listed separately, however, and the Nano has been updated this month. Can I use it in my N200? I've searched this forum and read you cannot use Nano Plus firmware in an N200, but the Nano is listed separately so I thought maybe it was a rebadged N200. Thanks!
Also, my battery cover broke. How can I go about getting a replacement? I looked through the online store and accessories, but didn't see anything.Message Edited by bookends on 06-22-2006 2:36 AM

The last update for the N200 added Thai support for the display.
The last update for the Nano Plus added Chinese and Japanese language support. This might not be of interest to most, but it is to me. I am also always interested in improvements in firmware revisions no matter how small. I also don't see a comprehensi've changelog, just a "changes since last version." The N200 and Nano Plus are basically identical, but why does the Nano Plus continue to get firmware revisions the N200 does not? There are obvious improvements the Nano Plus benefits from that the N200 does not. It doesn't make sense to me.

Z10 battery woes

I have had my z10 for a week, actually its the 2nd z10 in a week . i am getting 5 hrs battery life with all I can already disabled. I picked up 6 new phones last week ,1 is reasonable , 1 marginal and the 2 that I have tried are pitiful . The phone itself is fantastic,but with such a poor battery and almost no functionality left, its of no real use. I take it off charge at 5am by 10am flat, full charge 2 more times during the day ,put back on charge overnight 11pm-5am and go again. I was a high user with my last 3 blackberry's 2 Bold,1 Torch but Im not able to be with the z10.
Any ideas would be greatly appreciated as I'm looking to upgrade to a BES10 server at the moment and I don't really want to change brands
cheers

Hello.
Are you running on the latest OS? There are quite some battery improvements for the Z10.
If you cannot find a solution, I recommend purchasing a BlackBerry Z10 Extended Battery/Battery Case

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...

Bought a new iPhone 4s and dissapointed with the battery life (5.0.1)

Hi guys, I'm new to this forums and to an iPhone... I've bought my first iPhone 2 days ago (an iPhone 4s) and I must admit, the battery life simply *****! It's unbeliavable, typing a status and checking facebook drains 2% of my battery, this is just insane. I was glad to find out that I'm not the only one with this problem. I researched online and saw all of Apple customers complaint about it, and realised that Apple didn't really care as much until the media kicked in.
So yesterday I've downloaded the new 5.0.1 update, because Apple promised to fix the battery life issue, however I found no sing of battery improvement what so ever (my Location Services and Time Zone are both set to OFF). I think they've released this update in order to shut us up for a little bit, because Apple knows that it's not a bug BUT a hardware problem!
I hope Apple can come up with an idea to fix this problem a.s.a.p. or they're going to lose a lot of customers. I'm starting to slowly regret from not buying phones like BlackBerry 9900 Bold, Samsung Galaxy S2 or the new HTC. I'm so dissapointed in the battery life...
What do you think guys?

Community inquiry solicitation: Code improvement suggestions

AS the title of this thread implies, I am interested in improving the way I program. While continuing to work on a project, I found myself reaching back to old entry-level tricks learned early on to posit a solution to a problem.
however, I am interested to know what you old-hands have done to bring yourselves to a professional level and high quality of output such as robustness, compactness, etc.
Any input is welcome. I would not assume anything about me however as I am but a student so not much to expect there.

Yup. Heartily seconded. In fact, picking up a copy of JUnit and getting into the practise of setting up test harnesses for every class you write will probably help to bullet-proof (or at least rotten-egg-proof) you in the real world of unreasonable managers, expectations, deadlines and budgets.
This is interesting because it is something I do not do often and I suppose if a company creating door lock modules for an automobile will manufacture a test harness, I agree with it is the same process.No idea what you are trying to say, however...
- I am certain that car locks are tested.
- They are probably tested before insertion into the car.

Gingerbread 2.3.6 and Extended Battery Experiences

Someone else in another post had mentioned having reduced battery life after this update as I have been. Both of us have the extended battery. Anyone else have the extended battery life and seen improvement or losses of battery life?

For no reason I can figure out my battery life has improved drastically over the past few days. I posted more specifics about this in another thread where someone had been offering suggestions. http://community.vzw.com/t5/DROID-Charge-by-Samsung/Gingerbread-2-3-6-impressions/td-p/739350/highlight/false/page/5
Note that I have two posts on that page. The one where I detail the battery improvement is not at the top, it is #44, further down the page.

Battery Percentage Bar ???

I have a new iPhone 5C. Up until today I had no problems. This morning the battery percentage bar was all black but said 100%. I plugged it in and the bar was all green and still said 100%. When I remove the charger plug it goes back to being all black but keeps saying 100%. Can anyone assist with this issue please? Thanks.

Hi Lugi, thanks for your reply. I just wanted clarify here as some sites are claiming the downgrading is possible.
Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues
Downgrading "may" be "technically" possible through jailbreaking, which WILL VOID any and ALL warranty you may have and support from Apple and these forums ( Please read the ENTIRE article I linked to ).
You also put yourself at significant risk of turning your iPhone into a very expensive paperweight.

IPhone 4S 6.1.1 battery, with all the respect

I survived like a year on iOS 5 (purchased my 4S a year ago) and it was like fine and everything, updated to iOS 6, maybe it was in my head, but the battery improved a little, right now you 'f'ed up bigtime with your 6.1.1 update, I might be crazy, I'm only 19.5, but you gonna get the demons outta me..
After affording an iPhone, I gotta pay for some external battery case and sh..?
I ain't gonna "threat" with this I'm moving to bullsh..
But at least try to test sh' out before you release it.
I respect your work, but I don't feel any positive changes right now...

Weird sh.. happens bro.. I'm trying to be polite bro, I think I realized it but was idiot enough to go for it, still hope SOMEONE will notice that something is 'f'ed up (I'm talking about apple).
Peace !

Battery Life - Advice

Hi all,
Needing a little bit of advice - not sure if I am doing something wrong.
When I chose my MP3 player, I originally didn't want an i-Pod due to the fact I'd heard the battery life was rubbish. When we went to the shop to buy the Sony MP3 I wanted, we were basically talked into the i-Pod by a very enthusiastic salesman who was a hardcore i-Pod fan.
I've got the new 30gig video i-Pod and he told me that although it advertises around 20hrs battery life he said I could ideally expect between 6-10hrs of CONTINUOUS PLAY on the battery, which was fine.
However I am finding I am getting approx 1.5hrs of continuous play at the very most before my battery goes into the red from full.
Is this due to something I am doing wrong, or are all i-Pods generally like this? Or do you think its a problem with mine?
Any advice would be appreciated!!

From new, the iPod battery can take time getting to full potential. There are a lot of factors that affect battery usage such as what size your music files are, how often you use the click wheel or the backlight etc. As far as battery life goes, the hours Apple quotes are based on continual play of music files, AAC 128kbps file format, no backlight and no access via the scroll wheel during play. How long you get from your battery really depends on how you are using your iPod.
