Battery drain

My desire s battery drops from 100% to ~15% after about an hour of surfing with edge mobile network.(with different roms) And my friend tell me that this is unusual. I have tried calibrate the battery with the battery calibrate app and it didn't help . It's there anyway to solve this such as flashing baseband?
Thanks for helping.

first open battery usage and investigate which app eat a lot of power.
sometimes just restart the phone will clear out the issue.

The app which eat many power is the browser but I have tried other browsers too but same problem happened.
I have restarted and flashed tons of times and ROMs but same happened.

- which rom are you using? official or custom ?
- try to restart phone, donot open any browser and see if the battery still drain?

I tried cm stable, miui stable , HTC sense ROMs. It only drain when I surf with my edge mobile network. If I use WiFi its normally draining , about two to three hours.

with the same radio? or different?
if the same radio, try to flash another one
if problem with different radio, may be bad coverage in your location?
Try to move to another place with good coverage and give it a try

As i remember i never flashed the radio. Can u suggest which radio should i use?
Does baseband affect the battery life? If yes l, which baseband should I flash? Thx

Can we use that if i'm using hboot 2.00.002?

- firstly check to see what radio version are you using now?
- make sure your phone was rooted when calibrate battery. Is it rooted?

serious battery problem
OK, I have a serious problem. I updated official RUU, and my phone is running smooth. Battery lasts 1-2 days, everything is working fine. But last night battery was on 17% and I put it to charge at 12pm, woke up at 6am and it was on 33%. I'm charging it right now and it's up to 41% then drops to 39% and so on. Tried another charger - same thing. It won't charge! No new apps, no new settings, battery stats shows the same power use,.... Battery health is good, Auto sync is off,.... I have Go Power Master, Juice Defender, shows no problems. 3G is off, it's on GSM only, Wi-Fi is off, GPS is off and so on, my phone is fully optimised and this happened last night. I charged it while off and now it's on 37%! So I guess it's not a software issue. Anybody has an answer or a clue what could be the problem, please? Is my battery dead (year of use)? Thanks in advance.

try to restart your phone?

Tried that. I'm currently charging it power off, turned it on and it's still draining. While it's off!

i guess it's battery problem. Borrow another battery from your friend and try again.

Well, it was a strange thing... I've noticed that GO Power Master is killing like 25 apps and prolonging time for some 2 and a half hours when you hit optimise button every 2 minutes. So some apps are running in the back and draining the battery. So I uninstalled some of them (clock widget, Noom, Zoner antivirus,...) and restarted phone and by the end of the day it was all stabilised like before. I don't know what happened. I'm still testing it but I've managed to charge it to 100% and there was no drain over night. We'll see.

maybe you should look at this man..http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them

Noom
I have a S2 and every day, at 20:00 the phone starts a process and gets very hot and also drains the battery.
I discover that if I freeze the Noom app, it doesn't happen.
So, I blame noom for your draining issues and mine.
Does anybody else having this problem?
Regards

I didn't had a problem since uninstall, but it happened again later, I think it was from Firefox. While it was on charger, I got popup note saying something like "phone is using more than current can deliver, try to kill some apps or turn phone off while charging." First time I see that note. Probably because it was on Sense, not on launcher. I've noticed that Firefox is using a lot of memory, uninstalled it and it was all normal like before.

I had this problem, but svery time it was solved with rebooting. It showed normal percentage. I think, you just need to reboot device sometimes, may be once in two days. I suppose to think the couse of ghis problem is a kernel) it can be engaged with not an exact process, so battery drains. Try to change kernel, or rom, or battery)

Stock JB ROM as stated in OP, no root. Battery is just under a week old. I think it's the phone because I pulled the battery for a bit, put it back in and it was giving me a different number then started charging but very slowly.

maybe root and clear battery stats? Or just flash a stock rom and wipe data to see if the problem persists, if it does, then its probably a hardware issue.

I have this problem sometimes - the battery percentage reported by the phone while its booted into Android will be incorrect (fixed to correct % after rebooting). Sometimes my battery % will be stuck on a certain value for about 30 minutes either while discharging or charging.I find that pulling the battery and doing a clean install of a ROM with a full data wipe on a rooted device fixes the issues sometimes. Funny, there is no definitive fix for this problem that I've found. I guess some devices/batteries/ROMs are more susceptible?

Battery problem

+1 for the similar problem.... Kindly help me too.... I was about to post this question and i saw your post... Devs plz help us...
Heavy battery discharge + unable to charge battery till 100%, stuck at 83%... Done everything possible.. Using FlyROM v2 Kernel 3.0..

vishuhtc- You can try installing "better battery stats"(check out xda), or "GSam battery monitor", you will see what is killing it, if you don't get your answer with this apps check this thread http://forum.xda-developers.com/showthread.php?t=2093542 . Also if you are using super wipe, to flash roms, try flashing without it, or with it, but manually delete bootloader data, cos it doesn't do it automatikly
khanjan2khan- check out with the second app what voltage gets to your battery, it should be something like 4.000V or a little bit more, if it goes to that, you should also calibrate it or just delete battery stats from recovery, if it doesn't get to that............. try with another charger, or with a service center.

[Q] Phone dies at around 40% new battery

So I've bought a new battery for my nexus s and the problem is that it shuts down at around 40%, then when I plug it in it will show 0%. I looked around the forums and I have tried to calibrate the battery by resetting battery stats, draining it and then charging it to full. I have also gotten a replacement on the battery, still the same problem. The difference of these ones are that it is 1440 mAh and the original is 1500mAh. Does anyone have a suggestion to fix this problem?
Many thanks

What ROM and kernel are you using?
Either way, try a new or different ROM with a different kernel to see if does it on that one too.
Good luck

I'm using XenonHd rom and marmite kernel , I'll try and flash a different rom later. Also I don't get the problem with my stock battery it just happens on the other one which is strange. But thanks I'll give your suggestion ago

Yeah that's what I thought too, but another theory of mine is that its 60mAh different from the original so that have messed up battery meter on the phone, I've tried changing the kernel but still the same thing happens. I'll keep on trying to calibrate the battery meter to see if it makes any difference

Hi, it seems to be a bad "new" battery, anyway, to be sure, try to have a look which of your apps are running in the background, try to find if such app can cause a huge battery drain.
---------- Post added at 06:06 PM ---------- Previous post was at 05:59 PM ----------
And also, it seems your signal from the your operator is not very stable (=battery drain) - try to switch 2G only, try to switch-of wifi, on your screenshot - the battery collapse comes at 70% (?)

Update, I have just installed a new rom and kernel, and I think it is just a extremely inaccurate battery reading as it would also turn off at 40% on the battery icon in the status bar ( The graph shows that it dies off at a higher battery percentage which I'm not sure why". But after it dies, I can turn it back on and it would still have some battery life left, approximately another 20 mins of usage before it goes completely flat. So I think wiping the cache/davlik or installing the new rom made a slight difference.
'pgcz' The huge battery drain you may see from the battery graph is not battery drain, but it is me using the phone, playing apps etc. until it turns off so I can get a screen shot to upload onto here but thank you
I will keep on trying the battery calibration method I've found which hopefully would help, otherwise I'll just leave the situation as it is and keep the battery as a backup one

ok, I understood your graph now, anywat, if you are going to run new rom and kernel, I can recommend rom Jelly Shot v.3.2 (or upper) with Marmite 8.4 CM kernel

Battery is dying at 15%

For some reason my battery is consistently dying when the OS still notifies 15% remaining. I'm running the official CM11 nightlies 4/8, dalvik runtime, KT747 kernel. When it dies I plug in and it will say 0% again when I turn it back on.
Is there any standard procedure for this? Any tips on what I can do?

How old is your battery?
You probably need a new one.

Actually its rather new. I just got one of those Anker 2200 batteries about 3 months ago.

I have the same issue on my Nook Tablet. Running CM11 too. If it get's close to 15% it just dies sometimes. I think it's an android thing not hardware related. At least the CPU-z app shows my battery as healthy.

This happens with my S3 as well, and I resolved it by getting a different battery. I bought a couple different batteries to make sure it wasn't hardware/software related, and could only replicate said issue with my original “old" battery.
