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?

Tried this, but no difference.
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.
Hi ,
yesterday night i dint plug my phone to charging because my battery was above 70 % so i thought its more than enough for next day but i woke up in noon and saw that my phone was on 11% so took a screenshot thought that posting it here might help me

Try Installing soju factory image from google. I did a clean install wiping dalvic chache as well and my battery is awsome since then and I never disable google now. See in the attached screenshot how flat battery consumption curve when I am not using it.

I did the samething after getting terrible battery life due to an AudioOut_2 wakelock that never let my phone idle, and the same thing still happens. I'm wondering if a hardware malfunction could cause screwy behavior like this.
Just do "proper clean install", it should help.
Agree with clean install. ROM and kernel choice have a lot to do with battery drain also.
Was this a one time thing or the norm for your phone? If a one time thing wouldn't worry too much but would still shop for ROMs and do a clean install.
I have started using Juice Defender and LUX and my battery life has increased exponentially its features should help any ROM kernel combo.

i had a problem with android os sucking the life out of my battery, all was ok for about a week after i installed jb but then my battery life sucked. rather than do a clean instal i turned off auto sync for a couple of days then switched it back on again, since then my battery life has been good and android os has hardly used up any battery. might be worth while trying this first
Yeah. Full wipe is a last resort. At least if you figure out what actually caused it, you can prevent it from happening. I remember my Nexus S had this weird bug where if I put the phone in air plan mode and didn't disable auto sync, the phone would never properly sleep. Never had that issue on any other phone.
Its sometimes ROM related....codename ROM I get high android is but not with androxide

You have network disabled... Off course it does not drain!
I cannot tell much about your device setup since not all the details were given, But even my Sprint Nexus S 4G had horrible battery issues. The stock gingerbread was a joke, then the stock ICS did improve to do a couple more hours. Now running an rooted JB and it seems to do 1day and 3 hours at this time.

Turning off Google now is what fixed the battery drain for me. Tried other things but only this worked.
Recently i bought a new battery for my ace plus as the old one overcharged while using usb tethering stuck at 100 for hours and then turned off my phone. After recharging it normaly the battery life was reduced greatly.
The problem with the new one is that when it completes charging after 2 hours which is normal it stays at 99% for quite a time while using it and after that it drops 1% every 2-3 minutes if im using it to browse or play games. It takes 1.5 to 2 hours gaming to turn off a fully charged battery now. The 99 stuck thing is normal ?
Calibrating and deleting battery stats didnt help.

vickyg, I've also experiencing the same issues,
I have done battery calibration several times and tried juice defender, from 5-8 hours of battery life with average usage, my battery only improved to 12-13 hour battery life,
I've figured out that, the problems wasn't with the custom ROM or stock ROM. :silly:
I've dig some research and found that it may* due certain hardware problems, not sure

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:
How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.
CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.

probably it stops
i am not sure about that
edit: the point is the battery is increasing its percentage slower when it passes 60%-70%
but it charges the same
so if you reboot the device then it jumps at 90% or full charge

probably it stops
i am not sure about that
edit: the point is the battery is increasing its percentage slower when it passes 60%-70%
but it charges the same
so if you reboot the device then it jumps at 90% or full charge

Is it known what causes this?
Someone above said "it is a htc's common issue after rooting". Is there any source on that? For all I know, percentage of charge of battery is determined by a combination of output voltage and amps, preferably referenced by a table taking battery age into account (correct me if I'm wrong though).
Rooting the device should not be an issue, unless HTC did something in their rom to detect this and let the battery percentage be wrong. Then again, most of us aren't on the stock rom. To be on another rom, the bootloader needs to be unlocked. Did HTC do something that unlocking the bootloader makes voltage/discharge readings unreliable? I doubt that...
I'm interested in this because I unlocked and flashed a Sensation XE for a friend of mine (SultanXDA's KitKat rom), but the battery discharges very, very fast, without an obvious cause. So I wonder whether it could be the battery is not fully charged and/or the phone decides it's empty to early.
"it is a htc's common issue after rooting"<- i said that
it was a source but i can't find it now
also i don't know if htc did something with unlocking the bootloader by purpose
if you flashed the rom recently don't judge the battery too early
give it 4-5 cyrcle charges until it settles down then see how it goes

I have exactly this problem.
It sounds like the same ROM, Saltan kit kat. I am using the latest kernal 3.4, having tried two kernals I get the same results. For example I charged the phone to full, and after 2 hours of use I'm down to 55%, WiFi on and browsing, gmail synced but not much else, screen brightness turned down etc.
I only flashed a couple days ago, will it improve massively over the next few days?
The phone was giving a days charge easily before flashing.
I am also noticing a message saying 'unfortunately process com.android.phone has stopped working' (or similar). When this happens and I click OK I notice the signal disappears for a few seconds before coming back. Could this be the cause of the problem?
Could it be he ROM?
I'm new to all this but managed to unlock, root, flash recovery, and flash the ROM thanks to the brilliant guides on XDA. Any help with the above would be appreciated.

i am facing the same problem , rather my problem is goes much further .
iam on stock ROM and not rooted my sensation. my device often restart automatically even when battery is about 90% or battery is 40% and it continue this from last 2-3 months.
and after restarting battery percentage is also changed, see attached pics.
i am tired of this rebooting , i observed that restaring is mostly when i connect to calls or text msgs.
can somebody pleeeeeeaase help me.

since you are completely stock then the only thing i can tell you is to check your battery if it fits correctly
also how old is it?

thanks for ur reply ,
i have inserted plastic card behind battery for proper contact (adviced by many people at xda) but problem is not solved. my battary is 6 month old.
may be it is battery as i purchased from local market.
i have ordered new battery and soon will recive that . will let you know.
i have observed that mostly mobile got restart when i make/recieve calls and sms.

Does anyone have any ideas? Today the phone lasted around 12 hours but with minimal use which isn't really good enough. I thought rooting and flashing would improve battery life but so far I am disappointed. I may try another ROM tomorrow.

This really sounds like your battery, especially if it's not the original or equivalent. But, it could also be an app on the background, keeping your phone from "deep sleep". Bad cell coverage (very low signal) also drains your battery relatively quickly when you're on 3G. A good WiFi connection consumes less power than 3G with bad signal. Another possibility could be (but unlikely) is that your phone is intended for another region and thus having trouble communicating with the GSM network.
- Check your battery.
- Check what your battery is used for.
- Check your battery time with network set to GSM only.

Still you keep saying "after rooting" which is significantly different from unlocking the bootloader and flashing. Furthermore, to me it seems far more people report "better battery life" with their new roms.
About initially flashing the rom: i thought format of system, data and cache (including dalvik cache) ought to be enough. It has had somewhere between the 10 and 20 charge cycles by now. Battery life improved a little, but it's still far from acceptable. The battery percentage between reboots should only differ marginally between reboots (might need a few minutes of usage to become accurate). Also notable: over 20% difference in percentage reading between rom and recovery.
I wouldn't mind investigating this. So I wonder if anyone with "proper" battery life could provide me a "dumpsys" for the battery service and would perhaps have the time to take a look at /proc with me.

i unlocked the bootloader and root the device at the same period and i stayed for months with the stock rom
i don't know which one is responsible for percentage misreadings
also don't get confused
i am talking only for percentage misreadings and not for better battery life
and only when you charge the device.not unplugged
of course i had(and i still have) very good battery life with whatever rom i have flashed
by the way i have noticed the percentage difference between recovery and rom but i don't remember if it was 20%

Alright, thanks for clearing that up. I really want to solve this issue, so I'm quite keen on getting the facts straight.
Back to my issue then (yeah I'm effectively hijacking this thread): is it possible the percentage misreading is causing the battery not to fully charge and/or discharge? Or should I direct my search to another cause?
This is what I found (or did not find) so far:
- Stand-by time seems great, the drain occurs when the screen is on.
- There is nothing in the normal battery usage (usage goes to screen)
- I was unable to detect an obvious culprit with better battery stats.
- I did notice that when I do a dumpsys, service battery shows voltage in V, while my Sony shows it in mV.
- I tried offline charging for about an hour today (light still orange), after boot the battery indicator showed 100%. It dropped to 86% in 7 to 8 minutes.

probably never truly reached the full charge(100%) when charged it in that one hour
by the way how old is your battery?
did you try with a new one?
