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.

Hi iGoogleNexus, I tried the factory reset and battery calibrations, but did not try the ROM and Kernel you suggested, I will try that. Thanks very much for the suggestion, I will let you know if it works or not.

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,
Please help me, my phone is unusable. It keeps shutting down on its own. I charged it fully and within 2mins it got shutdown when i was watching a video, When i switched it on the battery % went down to 10% from 100%. What is the problem is it a motherboard problem?
Thanks,
Can you be a little more specific as regards to Rom, kernel?
To check your battery, remove it, keep it on a table n try to rotate it.if it does, it's swollen n gone.crude, but works.
Next , does it reboot randomly? If it does, flash to stock.even after this if it's rebooting, most likely a motherboard problem.
"why doesn't anybody kill the dj?"
yes it is swollen, stock rom and stock kernel. I will purchase a new won. thanks a lot mate. I found out that overcharging is one of the reasons that can cause this.

the best way to have a better battery life is to charge it when it has reached to a minimun level of 5% it extends ur battery life
Hai guys, i've a problem with my battery recently. Its been almost 2years since purchase of the device. There is a drop in 10% battery straight at exactly 30% to 20% and from 90% to 80% everytime. Is it to do with software or is it time to get a new battery? I'm rooted and running JB leak 3 on system 1 and MIUIV5 system 3. I've tried with wiping cache, dalvik cache and battery stats to no help.
I'm from India so would also request you to post a valid link for purchase of the extended battery and panel. Thank You. Any kind of help would be good.

It must be battery problem. I had same issue with my samsung mobile, Battery was like 80 to directly 40 % or less.. I changed battery and solved the problem. I suggest you to change battery and buy it from service centre only ..:good:

Issue fixed. It was a software issue only. I overclocked it to 1.2ghz and now the problem has vanished. Strange enough the battery feels dead cold even with heavy gaming. Strange things do happen. Need to figure out How to close this thread...

Hi Guys, i'm noob, i wana ask about my htc sensation, after 2 year i'm using it, today i found
when battery charging (htc Senstaion) dismiss displaying percentage of battery after i restarting while charging.
****battery charging ------> Battery percentage displaying 60% then i restarting the phone while this situation
and then when phone finish restarting and ready to use battery precentage displaying 100%(full)
is it normal?
sorry my english bad
Boot into recovery and wipe battery stats.

if not all many users(including me) have this situation
it is a htc's common issue after rooting the device
there is no a solution yet
it is just a percentage misreading
by the way i don't know if wipe battery stats will help

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.

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?

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?

please see attached screenshots
what do u think , is this battery or some hardware etc fault??
Running kitkat, battery recently replaced. all good for a month.
Yesterday the phone suddenly switched off , i switched it on again and the battery had jumped down about 40%.
It crashed again but then remained stable for the rest of the day.
Tonight (at 50% battery remaining) i got a sudden warning "6% battery remaining" and it crashed again, i switched on again and the battery went back to normal , around 40%, stable since.
Any ideas or is the phone on the way out ?
Did you buy an official N5 battery? It looks like a faulty battery...
This is the one i ordered

Phone seems ok today so far, would wiping the cache be worth a try ?
Thanks for the help.

It can't do any harm but it won't help in this situation.
Try the following:
1. Let the battery go to 5% then charge your device to 100%
2. Disconnect the cable
3. Reconnect it and check if the battery level is at 100%. If not keep charging. If 100% disconnect and reboot. Then reconnect until 100%
These steps worked for some users (even if steps 1 & 2 should be enough IMHO).
Moreover you can try to remove apps or flash the factory images to check if the problem persists. If nothing works then your last attempt is to send it back to ReplaceBase.
thanks for taking the time to reply, will try your suggestions,
Just had another strange battery drain, captured it on this screenshot.
You can see battery just takes a sudden dive and recovers somewhat.

I have just read a nice thread about massive battery drain. Check this out.
His explanations fit with your battery stats.
Thanks for that, will have a browse, but would it explain my phone suddenly dying at 50% ?

I guess. Anyway you should follow the above steps and clean up your device by removing useless apps/features. Finally flashing factory images is sometimes a good thing to start from scratch.
Thanks again
I just tried your first suggestion, charged till 100% then disconnect, it immediately dropped to 99% so i recharged to 100%
Then disconnected and rebooted, weirdly when the phone rebooted it said the battery was now at 19% ,
Back on charge again.
Ugh.... Good luck but I would bet on a faulty battery. You'll probably have to send it back if you can use the warranty.
Did you have the same issue after receiving the new battery? Did you change several things of your setup (kernel, new apps...)?
Going from 100% to 19% can't be explained by the above thread. IMO no apps, no kernel, no software can explain this drop. Some folks say that it can also be caused by the motherboard...
Replacebase have promised to send me out a new battery , they too think its likely a dodgy battery, top customer service so far, hopefully it wont take too long to arrive.
I didnt change anything on my phone, perhaps updated some apps , its stock Kitkat,,, meanwhile Is there any way to check the health of the motherboard ? i don't like the sound of that.

Without profesionnal tools we can't check this AFAIK. Don't worry about the motherboard. It was only a suggestion reported by a few users. Chances are your problem will be solved after receiving the new battery.
ok thought as much, battery charged up to 100%, rebooted and now at 60%.
Ill put back in the old battery for now and see how it behaves. thanks for you help
