[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...

First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next

And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.

you might want to try a new radio too

same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????

I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(

Yeah this is no fun...

battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?

It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

well after the screen 40% we have android OS @ lower 30%

Do you have an SD-Card in?
I was getting the same battery life, took out my SD-Card, and I'm getting 7 hours on screen time with stock battery.

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.

GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.

It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....

[Q] Terrible battery life on jellybean aosp roms

My battery life is considerably worse on jellybean aosp roms (I tried both the 4.1 and 4.2 version) than it was with stock ICS, and stock jellybean with sense, I'm sure that the battery lasted at least twice as much than it does now. I'm getting around 7-8 hours with a screen time of 2 - 2.5 hours at maxiumum, screen brightness at 50%, location turned off. It's clearly a software problem since the battery life with stock rom is so much better. Something must be wrong since everyone is reporting great battery life with the latest jellybean aosp rom.

I think you maybe hurrying to a conclusion.
After you flash the flash the ROM, wipe battery stats in cwm. Then let the ROM settle ( atleast 2 charge cycles ) .
Then see if you have the same battery problem

I'm on ice cold jelly 2.2 with the XML kernel #141repacked for the ROM. I get a steady 3 hours screen on time. Give that combo a try. Also the first few days the kernel and ROM have to settle so don't be too quick to judge it.

Thank you so much! I have deleted the battery stats file in cwm and it is immediately obvious that the battery life has improved.I can't believe how easy the fix was.

Sorry for the replies, but: the battery stats wipe is useless...
The file that you've removed is a file which contains the statics of battery.
It has nothing to do with the battery life, Google has confirmed this.
In fact, in TWRP and 4EXT recovery this wipe there isn't.
However, i think you have to calibrate your battery with some charge cycles

Guich, what i talked about was not fixing battery, just fixing the readings.
Example : especially on AOSP roms, if u put on charge, after some time green LED shows (meaning charge full) BUT battery bar is stuck at a lower level ( Example 76 ) .
And the bar doesnt move forward even after you keep it on charge even longer.
So i tried a battery stats wipe in cwm and then when i booted back, it properly showed 100%.
So what i recommended was to delete previous stats ( of different ROM which were carried into this one).
So now the phone starts monitoring battery anew (with no cache).
Sorry if you misunderstood me.

I think this fact is random.
In fact, all aosp rom that i tried didn't have this problem
And, teorically, this file was delete when you made a full wipe.
In fact in TWRP recovery there isn't the wipe for the battery

Battery stats file should be deleted each full charge, though I have noticed my phone crash (my fault messing about with UV) and then my batter jump from 8% to 45% which is quite a jump lol

I'm familiar with CWM, but I cannot find it in advanced menu.
Is it because after I upgrading my HumberOS CM10.1 to AOSP 3.15?
I did a wipe clean. Everything. Fresh install.
It happened after I finished upgrading to AOSP ROM 3.15. My battery shows nothing even I charged it for a whole night.
Only 2% batt left while I'm typing this message. I have to connect my SGT7 to charger but nothing happened. It shows that it's charging but too bad, its not.
I've never encounter this problem before. It would be nice & I would be grateful if you sir can help me through this problem.
Thanks for replying.

Huge battery drain overnight (all off) with JB 4.3

Almost 15% of battery drain overnight in 9 hours, with 3G, WIFI and SYNC off, only 2G active.
Yesterday I had 20% of battery drain.
Can please someone help by having a look at the better battery Stats screenshots?
thanks

I don't know if you're Maguro or Toro, but you need to have a data connection or this phone will chug battery. This phone is notorious for chugging through battery when looking for a data connection.

1st time I ever read this...
I have Maguro
left it with wifi and 3g on tonite and list 22%

no one else?

Might be helpful if you name your ROM, kernel and carrier. I have a Maguro with JellyBeer and the newest Golden Kernel of today (with some Trickster mod changes) and only getting like max 5% drain a night.
Edit;
I see it in your sig, so stock 4.3 ROM? I am on 4.2.2 so can't really compare it. Are you in a bad connection zone there? Any unnecesary apps running?

yes, stock 4.3, very good 2G signal, no apps running in background (well I have facebook, but not messenger, and all google apps, of which i use only gmail, gmap and gcalendar, g+ is not connected, still at night sync is off).
if you have a look at the three screenshot on my first post, you will see the servioces causing wakelocks

If you look, the 1 and 2 screenshot didn't influence a lot on battery.. It looks high, but if you pay attention, it's draining 0.9%..1% so, not the beest battery life, but "normal". If you pay attention now on "deepsleep" screenshot, you will see that it drained most of the battery during the night.. So, my conclusion? Maybe some problematic gapps , trying to connect to some server to sync even with sync off, try another gapps. Second option : flash another kernel, it could be caused by kernel keeping the phone awake even when it's trying to deepsleep
Edit : almost forgot.. You could try to connect to wifi, and leave the phone for some hours with sync enabled.. It would sync what the phone tries to sync and fails during the night.. Sounds crazy, but solved my problem once!

with wifi on it drained 22% in 7 hours

besides... I not sure how u r reading the screenshot but the one for "other" simply says that of the total monitored time of 9h 14m 54s the phone was in deep sleep for the 96.2% of the time

[Q] Can't fix battery drain...

Hey guys,
my Endeavoru PVT (Tegra3 International) is now about one and a half year old, I can't remember how it was in the beginning, but now my battery drain is too heavy in my opinion.
At first I had AHRD, then I switched between some ROMs but now I am stuck at CyanogenMod 10.1.3 because as time went by, I started to hate Sense and I love the standard Android look. The thing is, since I switched from OrDroid to CM 10.2 or better said from Android 4.1 to 4.2+, the drain got heavy.
I removed all wakelocks, I use XM-Kernel with Smartmax+Row and limited the CPU freq, I turned off sync, gps and I only use 3G if I need the speed.
I mostly use whatsapp and rarely browse the internet with my phone, when I wake up at 7:00 AM I disconnect it from the charging cable, then I go to work etc. and at about 9:00 PM the battery only has 20-30% left and the average screen on time is maximum 2 hours overall and that's clearly not ok...
As I already said, I removed all wakelocks, the only wakelocks come from the kernel when the screen is active. So please do not link the ultimate battery life thread or something like that... I have no wakelocks and my settings are ok.
And when I start gaming, the battery drains 1% per minute which is insane! So I can't play any games at all.
With OrDroid and XM-Kernel I had the best battery life and almost no bugs.
Today I wanted to install Skydragon 2.0, but it was pretty buggy. So I switched to AHRD but with the XM-Kernel (17 beta for Sense5) my computer didn't detect the One X, I switched back to Stock Kernel, then it got recognized but the files were all displayed like a mess and I couln't copy any files onto the One X. Then I was pissed and restored my CM 10.1.3 backup... Is there any way to fix this??? Please no mass storage mods, these are not stable and don't work sometimes..
A few days ago I bought a One X+ battery, it should arrive next week. Maybe the battery is broken, but that doesn't explain why it drains so fkng much battery when I start to play games! And it doesn't fix my problems with Skydragon or AHRD. I would love to stay at CM, but there are the common issues which force me to switch to a sense rom.
I will probably switch back to OrDroid with XM-Kernel when the new battery arrives, hopefully it will fix the heavy drain. Can someone explain what could cause this massive drain? I mean, a phone should last at least 24 hours not 14...
Or is there any fully working AOSP rom with Android 4.1 for the One X? So I could benefit from the battery life and the look of Android 4.1.

Did you try erasing your sd card? Corrupt files might cause heavy media drain on aosp without showing wakelocks. I would recommend trying a sense 5 Rom, get a custom kernel and set it to smartmax and row like you are used to. If that doesn't work, replacing the battery is your last call. Good luck!

Go for a full wipe of your device & SD card first than try installing anew sense 5 rom and see whether the issue still persists?

My sdcard is almost empty and the problem doesn't only happen on aosp but on all Android 4.2 or higher roms.
Did you even read my post? I already said, I tried Skydragon and ARHD and I had bugs... and yes, I made a full wipe 3 times.

Stop being rude to someone trying to help you. Yes I did read your post obviously. You didn't state if you wiped your sd card. So what do you expect from the community if you figured it out all by yourself? If it's not the software it's the hardware, replace the battery.

I didn't meant the part with the sd card, I meant the sentence were you said I should try a sense rom, which I already tried as I stated.
I'm sorry if you interpreted my post as an insult.
Edit: Ok I fixed the USB problem, I installed the newest HBoot and used lyapotas Kernel, now it works without problems. Now I'm going to fix all wakelocks and wait for my new battery.
I removed all wakelocks now and I got about one hour more since then, but at some times the drain is heavyer, I tried to backtrace the drain with GSAM and BBS (root) but there are no Problems with wakelocks. The battery drained from one minute to the other from 72 to 78, I don't know if the stats didn't refresh correctly, but I am now pretty sure it's the battery.

Okay, my battery arrived. I replaced it and besides I fixed my Wi-Fi with a piece of aluminium foil. The drain on the first start was heavy, but I think it has to undergo some full charges to calibrate.
But I have one more problem.. I'm on ARHD 33.1 with lyapotas LM kernel (XM beta didn't work very well), but I can't undervolt with SetCPU (paid for root version). Every time I want to save the undervolt settings SetCPU itself crashes and I don't really want to use TricksterMod for undervolting.
Is it because of lyapotas kernel?
I already reinstalled SetCPU two times..
Update: Wow, I never had 78% battery left after work! I guess it was my battery that was broken, so the thread can be closed.
