Hey,
This is my first android phone and i love it but the battery sucks. Last night i unplugged at 9pm with minimal use maybe like 5 mins and it was at 58% at 2am. I ran stock gingerbread for a couple days and yesterday i put the virtous unity rom. No significant battery improvement. Shouod i get a different rom, flash a new radio or what? I havent flashed the radio.
It may be weak signal where you are. I can charge my phone Thursday night and not need to again until Sunday night at home on either ClearDroid or VU but at work, from 5:30 am, I need to charge it by 2:30 pm.
I have also noticed with VU, with WiFi on it doesn't really sleep and I get significantly worse battery life even with great WiFi signal.

I really really wish you would search these things, hundreds of threads about this topic (ok that's a lie but there are tons). I'll point you in the right direction on how to get everything you need to properly diagnose your battery issue as well as offer some additional tips and advice. I by no means, say that this should be the ends of your search but this should get you moving in the right direction. If you do take to a new ROM, my best battery life have been with Android Revolution, Virtuous Unity and BinDroid, I will shameless plug BinDroid because it's been the most stable rom I've used and amazing quality (not to say the others ROMs aren't, I just fancy this one). Good luck with battery issue! If this helped ya, you know where the Thanks button PM me if you need any additional information, I had some battery drain issues as well and I know how annoying it can be!
Good please to start

Yeah, this one too.

I am very sorry to open a new thread about battery drain that has been discussed so many times but I am really desperate.
I recently purchased a second hand Nexus S i9020A (unlocked AT&T version) from swappa. (Website that sells only android phones) and I am getting terrible battery life no matter what I try.
The phone is rooted and have tried several ICS roms and all have terrible battery life about 6-7 hours when the phone is on idle for most of the time.
I then installed CM7 as I read that ICS has some battery drain issues, but I still get really bad battery life 6.5-7.5 hours again the phone is on idle for most of the time.
I also tried several kernels.
I tried disabling the WIFI, GPS etc this did not help.
The phone came with two batteries an Anker Battery and the Samsung battery. I sent Anker an email asking them about the battery life, they told me to let the battery discharge to around 10% and recharge to 100% a couple of times. I did this twice, but no improvement in the battery life I was about to do it a third time when I fell asleep the battery must have drained completely and now that battery seems to no longer be working.
I thought maybe I am really unlucky and I got two bad batteries, so I purchased a new RND Battery from Amazon as I thought maybe there were some problems with the Anker. Turned off the phone let it charge for 7.5 hours, but the battery meter still showed that it was not fully charged, but the instructions said to charge for at least 5-6 hours, so I turned on and unfortunately I have the same battery drain.
I have installed a Battery Calibration app from the Android Market to see what the reading was and when the phone read 100% charge it was a little over 4,000 mV . I am not sure if this is what it is supposed to be, maybe one of you can let me know.
In addition I have wiped the battery stats from from the bootloader a few times after I have fully charged the battery and even factory reset the phone but this made no difference.
Last night I even flashed a new radio I went from I9020AUCKF1 to KB3 but this also made no difference. I have been struggling with this problem for about a week with no improvement what so ever.
I read that its bad to completely discharge Li-on batteries, so before I left home to go out, I turned off the phone so that the battery would not discharge, when I arrived home a few hours later the battery was dead even though the phone was turned off. (this was the original Samsung battery not the new battery I purchased, I did not try this with the new battery as yet)
I checked the battery usage and compared it to a Galaxy S2 to see what was using up the battery and the OS and Screen usage % seems to be comparable amount to the GS2.
I also tried a few of the Governors that are included with CM7 and also used the wheatly Governor when I was on ICS, but it made no difference.
Can any one help me? Is there something wrong with the phone? I purchased this as a present for someone who really wanted an iPhone because I could not afford an unlocked iPhone and they are really disappointed by this. I know this may be an isolated case, but I always assured the person that the android phone can do everything the iPhone can do, but not I feel like such a fool.
Can this be fixed? I purchased this when I was in the US but now I am away so returning it would be a problem. Is there a way to check if there is something wrong with the phone itself that's causing the battery to drain at such a fast rate?
Any one that can help me I would really appreciate it and be very thankful, I know there are other topics that deal with battery issues, but I have been researching this for about a week and tried everything I can, I didn't just start a new thread without trying.
The screenshot below shows a high display usage because I was using the phone to try to troubleshoot normally android system uses the most and display is closer to 7% but the uptime is the same. Even though it says 3h 51 mins at 48% in the screenshot the battery seems to discharge faster as it percentage goes down.
Can you enter this code and check for battery information:
*#*#4636#*#*
You can check the battery health and temperature. It might give you some insights.
Do you have good reception? Is it constantly trying to connect to 3G networks? Can you check apps which might be trying to connect to Internet all the time? Do you have this problem once you flash a clean rom (or maybe it starts after installing apps)? Have you tried stock ROM?

I've read about this in other threads... not sure if I've already tried it... ull need to do a factory reset to wipe all data and battery calibrations. Once u reset... flash Evilistos ICS rom 4.0.4 and use the Air Kernel 3.0 .... flash the Tweaked Nexus Boot Animation (looks really nice but you don't need too lol) and that should do it... =]

Hi Oogway first of all thanks a whole lot for your response.
I dialed the number and got the following
Battery Status : Discharging
Power Plug : Unplugged
Battery Level : 100
Battery Scale : 100
Battery health : Good
Battery Voltage : 4096 mV
Battery Temp : 34.0 C
Battery Technology : Li-ion
Time since boot : 9:58
Just finished charging it again.
I have good reception, but I have no data plan on this phone so it isn't using any 3G, actually I don't even have 3G in my country :|
I have no apps installed and the problems still happen even with a clean install. Before the person shipped the phone to me I asked them to install the stock rom and when I got it the problem was present, since then I tried different roms but to no avail so far.
Thanks very much for your time and effort in offering possible solutions, I am grateful for your help.

Its not a new phone its a used phone, but the seller has agreed to refund me if needed, the problem though is that I bought the phone in the US but I am not in the US now, if I return it to him he may be charged taxes etc.
I returned the phone and radio to stock, but it seems the issue is still present. Any more ideas?

Did you buy through Ebay? Perhaps you can print out your receipt and get a warranty repair through Samsung. That's what i did when i deleted my imei. Cost me nothing except postage.

I have abyssmal battery as well with my used i9020t. Although I have only used various ICS so far and don't know how used the battery is.
At night I put it to airplane mode and closed running apps. In the morning the phone feels warm and battery drained drastically, which makes no sense.
I just got an Anker battery as well and will try some Gingerbread rom. For now I'm using Franco kernal and undervolting by 50mV which help a bit, but not much.

Hi Bedalus, I bought it on swappa. I bought a few phones there before without any problems. I have a paypal receipt from swappa, maybe I can email samsung and find out if they can repair or not. I honestly think its a hardware issue now. Because the battery still drains even when the phone is off. I flashed several radios and roms, wiped battery stats, changed battery, wipe data and factory reset and its all the same.
My issue though is that I am not in the US and the phone was purchased from the US so return may be a problem as well as shipping to Samsung, but I will email them to find out more.
But thanks for your suggestion Bedalus, really appreciate it.

Hi Ekasol, does your battery drain even when the phone is off like mine? How much battery life do you typically get? I get around 6 hours. Just to let you know that I did flash the stock ROM on the phone but it made no difference to me.
Mine is the AT&T version, I got the roms here .. http://forum.xda-developers.com/showthread.php?t=1445621
But you can get the roms for yours here http://forum.xda-developers.com/showthread.php?t=1063664 in case you have not found the original roms yet. Best of luck, I hope at least one of us is able to get the phone working or repaired.

Bedalus, before I contact Samsung, do you know if rooting and installing custom roms void the warranty?
Technically yes. However, if you wipe, install a stock rom and bootloader and lock the bootloader afterward, they have no way to tell.
Thanks Harbb
Can you try this Gingerbread rom NSCollab anyway, I know you said you tried GB already. I don't have time to test with full battery yet, but Gingerbread seem to retain battery life pretty well.
If you still have time, I would say save yourself the hassle and return it, it sounded like hardware issue. And buy the person an iPhone instead. If he/she is not tech savvy it is pointless and will just give the person a difficult time. I do not have an iPhone, but I have to do iPhone tech support for my co-workers, Android would just be a nightmare.
Also if the person don't mind going with T-Mobile, see if you can return it and get a Galaxy S 4G. It is one of my favorite phone. No LED flash and ICS (yet), but you get microSD slot and HSPA+ 21Mbps (cheaper plans too). And best of all the Valhalla roms.
Tried NSCollab, battery drain seems to be a little worse with this ROM. The reason I did not purchase the iphone is because of the cost, I got this for around $260. Thanks for the suggestions though, I will consider them, but so far it looks like this phone has some hardware problems.
I was on GB and had amazing battery life!
Just flashed AOKP milestone 6 and I can can't watch
The battery drain.
I've read forums and not much help.
I DL better battery but don't really know how to use.
I tried formatting battery stats.
Any solutions?
I am having the same issue. I am going yo try cMIUI. what are you getting for battery life?

Are y'all sure it's not just because you're doing lots of stuff with your phone right now, having just flashed a new ROM?
If it's an extreme amount of battery drain, it might be some leftovers from whatever you had last. You could try a factory reset and then see how stock AOKP handles battery drain.
I know I don't get battery life as good as I did with Octane, but a big part of that is because I've been flashing the new AOKP builds every couple of days, so things don't get a chance to settle down. (Granted, battery life still isn't as good as when I just flashed Octane.)
There is tons of things regarding this very issue in the AOKP q & a thread. Please use the search this thread button in that thread. Ive typed a response atleast four times today. And atleast four yesterday and more the day before and the day before that. NOt trying to be a ****, but Im tired of typing and responding. If you cant be bothered to read the thread or search I cant be bothered to respond anymore.
Not sure for sure.
But I get 5-6 hours on full charge with medium use(text. Instagram. Web.)
How can I get exact info?
Read the AOKP Q&A, yes, the whole thing
Read the OP's instructions on the AOKP dev thread
Read the thread on Bettter Battery Stats
Listen to what people say about battery use
Think about what you have done and what to try next
Do
Rinse
Repeat
Ask yourself "Why am I flashing ICS at all?" -- ICS in the SGS4G is still very much in development.
I don't think you realize how unreasonable it is to ask someone to read that entire Q&A. I've followed the thread from its beginning, and there's no real solution to the battery issue being described here. You'd only be wasting everyone's time who took your advice. I've also read all of OP's instructions in the AOKP dev thread, and have even tried the gremlin remover prior to flashing AOKP. This does not solve the battery issue. You're seeming to imply that the battery issue is the user's fault, and I think that's not even remotely close to the truth. I've done multiple flashes, each time trying something different, to see if I did anything to cause the horrible battery in AOKP, and they all concluded the same way. With that said, we need to actually try to fix this, instead of sending people in circles and pretending to fix it.
First of I dont have battery issues at all with AOKP I am a User a very grateful user (thx 2 our devs). Just factory reset, after that wipe cache, system, everything except your sd card of course) and the flash your rom. Its really a matter of re-assuring everything is wiped. Also leave your phone alone for awhile I left mine around 2 hrs alone, while the rom settles.

Go to the Gremlin Remover dev thread, and try steps 1-3. If you are STILL having exaggerated battery loss, try using gremlin remover it'self. If you still have problems, after making it back to your preferred rom, just put the phone down for a while.

Some of us are getting good-very good battery life, and some of us are not - using the same exact ROM. I don't know what that tells you, but what it tells me is that it *is* likely to be a user issue.
People complain about battery life, but they hardly ever talk about the total time they are using it (including fiddling around with it), what programs they have used or have installed, and how they are restoring after they flash (i.e., if there is a chance they are bringing along bad stuff from a previous incarnation of the phone). More information about these things and - yes - doing tedious things like the process of elimination might be enlightening here.

Ya know when I first came here I said something similar. But Ive kept up with these threads now and I know for a fact battery life issues have been discussed to a point that the devs are ready to pack up and leave. Nobody wants to read or even search. Instead the battery life issues are blamed on the shotty coding of the people building these roms. If you are getting bad battery life it is plain and simple a user error. Unless you can provide logs stating otherwise then just drop it try what is being suggested or go back to stock roms. Install all the apps you need to customize the phone like it is on the ics variants and then report back here. I garandamntee you will have ****ty battery life.
These custom roms have so much stuff added to them that is hard coded in for customization that its not going to have super battery life like a unbloated stock rom. But you cant expect it to. A good comparision was made earlier in another thread. Would you expect to get 8 hours out of a laptop battery?
I always tell people to make sure to completely drain the battery....all the way until it shuts off, because mine will sometimes stay at 1% for nearly 2 hours.
Seems like it doesn't know its own scale until you do that a few times.
Also never ever ever restart this phone while having it plugged in or turn it on while plugged in.
Let me give you the scenario, it will be charging let's say around 50% and then after restart while plugged in right around 75-80% and that little act took me a long time to recalibrate my battery and I'm not talking about deleting the battery stats, I don't delete battery stats anymore at all (read an article from Google saying its pointless)
All that said I'm a very heavy user, and I like a bright screen and I'm getting (what I would consider) good battery life. But I have a 3500mah so its never too bad for me
Hope this helps someone

I'm on AOKP, and my battery life is GREAT. There are plenty of steps and tips mentioned here to find out what your battery problem is.
I would like to see screen shots of the battery usage of people that have crappy battery.
From home hit menu>settings>scroll down a bit to battery.
Take two screenshots one of the initial screen, then touch the graph at the top and take one of that screen.
I keep hearing battery life is horrible I only get 4 hours, please fix this, hows battery life..blah blah blah battery. Yet nobody will drop usage stats, logs of a days use, offer anything but i use my phone moderately. I call bull**** on that, How many texts do you get/send in a day? How long are you on the phone making calls? Do you live in a poor service area? Give some info.
On a average day I get about 50 texts, might make a 20 minute call, use tapatalk a half dozen times, and use tweetcaster and flipboard a dozen times. I can get 12-15 hours out of a full charge. To me that is light to moderate use. I get crappy data where Im at right now so Im on wifi A LOT. When Im actually using t-mo data more I can get closer to 18 hours out of a charge
People if your having problems with battery life stop rebooting the phone a hundred times a day. Stop shutting off all the radios thinking it will help. use the dang phone like it was meant to be used. None of the code is optimized for people to shut radios off and turn the phone into a dumbphone. You are making it worse by shutting these things down and turning them back on. It takes power to properly shut off bt, wifi, data. Next time you do watch the radio will not just instantly shut down. It has to power off all the service that is using it and then power down. Otherwise you would be here *****ing about tons of force closes.
I get about 17hours on my phone and i have a stock battery. I use all the extras PROVIDED TO US BY THE DEV like turn off wifi/date off or to 2g while phone screen is off. Auto bright and all the extras.

I usually get 14-17 hrs doing the same. No battery issues. If you leave data/wifi on all day and are constantly checking email, Twitter, and Facebook what do you expect? Battery is fine.

How much time do you spend on "screen"?
My phone usually drains 10% each 5hours of sleeping (air plane mode). Is that normal? I can get around 3hours of web surfing,which is less than it was on SCOM (4hours).

Hi all, just got my 11yr old son a ChaCha. He wanted a Blackberry for the keyboard, but managed to persuade him to have the ChaCha. Anyway, it seems to have this infamous dialer bug.From reading throu the forums, am I right in thinking that if I put a custom rom on, it will get rid of the dialer bug? He curently takes it to school, at 100% power, and generally comes home with the phone on around 10-20% power!! He is only allowed to use it at break and lunchtime!! Also, as it's for my kid, I would like it to be as close to stock as possible. Any recommendations? As I already own a customised Desire, I am happy to 'play about'. I have already unlocked the bootloader, and rooted, so that I can use link2sd. Without that he could only install 3 apps on it before it got the low disk space warning!! And as he's only 11, he likes to put a lot of junk on his phone!! Any help would be most appreacited. Thanks.
Like I mentioned here, I don't think that the dialer bug really exists. It's just the battery statistics that are not very clear.
The overall battery performance of the Chacha is very bad, so if you play some games they could drown the battery within an hour. There only thing you could do is rooting the phone and using another ROM. You can win a little with this, but for playing games, Chacha has a very bad battery performance.
Best performance was with CM7 - there my battery live was 1 1/2 days (without playing games), with CM9 now it's less then a day again.
So for better battery performance and keyboard I guess the Motorola Pro is the only phone, or non-Android phones.
I agree. There is no dialer bug. Those are many processes that show as Dialer. I don't mean to offend you, but have you considered that your son is using the phone not just at break and lunchtime? It is hard to resist, especially when it comes to new things. You should test it yourself and see if battery drains that much in that specific time frame.
Regards
Custom ROM would be a good option, but as he's 11, he's probably not old enough to appreciate the faster speed of CM7 or CM9, over his front camera. I'm guessing he'd want his front camera to keep on working lol
But when I was using the stock rom, I just turned my 3G data off whenever I was not using it, and that makes the battery last miles longer
For easyness (lazyness). Create a widget on the homescreen, under Settings and Mobile Internet. And then you'll have a widget you can just tap to turn on and off the mobile data as long as your son can get the hang off turning it off when he's not using it, then that should work a treat
go for CM Roms
IMHO I do believe that there's a dialer bug in stock Chacha, I think it is caused by the dialer's continuous polling of the proximity sensor (this bug has been reported in a lot of htc stock gingerbread phones, the app dx battery helped me confirm this.) Custom ROMs helped me solved this bug but only those that are CM-based (stock-based roms still has the dialer bug). CM7 is very stable and has the best battery life for any Chacha ROM but CM9 just looks so damn good and the battery life is still way better than stock (in stock, I get battery drains even if my phone is just idle, wifi off)
Thanks for the advice guys. I think we will leave it a couple of weeks and see how it goes. May end up putting CM7 on it at some stage, as I have a CM7 based ROM on my desire. He is only allowed to use it between lessons, otherwise it's detention!! He also uses it to listen to music to and from school. And yes, I have notice that the battery goes down rather quickly, when I was setting it up for him.
Well, there sure is a bug in the stock rom that drains it within hours. IMO it's coming from the 3G connection... Sometimes, when my coworkers drive me crazy, I turn off the 3G... I live in a neighbourhood with a bad network connection, this means that it is reconnecting all the time. My battery normally went for about 15 hours, with 3G off it works for over 20 hours. But since I've installed CM9 it stays alive for over 40 hours...

I flashed the VRBLK1 build a few days ago with the Rom Manager app and everything seems to work great except for the battery life, even with 4g turned off with the Phone Info app. Just sitting on standby drains about 3-5% of the battery per hour. I am running full stock, unbloated, rooted & unlocked. Is any one else experiencing this with this build? Is there a better kernel for battery usage or a rom that has a few customization's to run better without getting into a fully cutom rom? I'm probably one of a few but I actually like touchwiz for the most part. Also I was searching around and found a link off of droid_life.com and it shows the newest leak being VRBLK3. Any info on that build? I searched here but couldn't find anything for that build. I tend to only trust downloads and such from xda. Never had a problem with what you guys put out!
Well I found the newest leak (VRBLK3) on here and flashed that with Odin and rooted and unlocked bootloader. But my battery still seems to be draining way to quick even when the phone is sleeping. Any suggestions on getting better battery life. Maybe a bad battery? Or am I just delusional in how long I think a battery should last?
I see a lot of posts about mediaserver killing the battery, have you checked that?

When I check battery usage the top three are Android System 51%, Screen 15% and Media 7%. Is the Media what you are referring to with media server?
battery life my be ****ty on the first charge cycle... then you should see a big improvement once media server settles down.
Yeah let it settle. After every newly flashed Rom, the phone needs to "organize" all the media on the device. Once that is done, phone should be back to normal. This process could take a while, depending on how much media is present.
Sorry I haven't replied in several days, went out of town and dint check the forum. Thanks for the advice! My battery is lasting a lot longer now, I am easily going all day depending on how much I use 4G and such. I guess what it needed was time for the media server to settle like you guys said. Thanks again for the advice!
