Hi all,
Since I started using Lite'ning ROM v2.1 I noticed that my battery was draining very fast.
I went to my battery use and I saw that "Android system"was using 44% of my battery. Wake time is almost 6 hours...
Is this a known bug or is there a solution to this?
Battery drain start with the Better Battery Stats app and thread .

If the rom you are using is not yet a fully stable rom then it could have battery drain problems, although battery drain is usally how you use your phone. Look what apps are running when you notice your battery running down fast, as it could be one of those.
When im at work i actually only use whatsapp, and sometimes facebook while im on break. But my WiFi is off all the time then, only whatsapp and battery monitor were active. With 2.3.4 this wasn't a problem and my battery would be 60% when i came home...
Either google wakelocks and how to pin-point them, or wipe and install NO apps afterwards, run it for a day and if the same problem go to another rom till it's more stable .
What works fine in 2.3.4 has no garuntee's that it will work an experimental ICS build of any sort.
i have similar problem. my galaxy is on wanamlite 9.6, which base on LP7. after 5 hours of not intensive using, i have 65% battery left, android OS use 68% of this battery, most of time my wi-fi is off. when is on, drain battery very fast, over night even up to 20%. when i was on ginger bread it took around 6% - 8% with data and wi-fi on.

Do you have many widgets?
Especially Beautiful Widgets and Fancy Widget (moreover if you activate the meteo forecast) will constantly drain your batter in search for your position. Wifi uses less juice than 3G connections.
Happened to me back at GB 2.3.4. Battery went down to 60% in 3 hours (at the office I'm on G...so even worse cuz the battery compensates for the lack of coverage). After I removed Fancy Widgets from the screen everything went back to normal.
Don't have any widgets as far as I know, only the clock and twitter...
Today battery is know at 26% after 11 hours on battery. Process stil at 39% battery use.
I searched the web and found that there are a lot of users having this problem, especially with the Google Nexus.

hi guys!
i have a problem! lol =p
my battery is crazy, or my phone is crazy and is draining all my battery
it starded some days ago ... i'm using the Internet Browser and (sometimes) it starts to get really hot on the superior part of the phone ... and my battery starts to drain really fast... if i reboot sometimes it gets back to normal, but there are times that the battery goes crazy and happens like the picture below... after that i turned the "battery save" mode of the phone, and the battery percentage increased by 1% even without charging ...
It started to happen even before i updated to ICS, and still happens with the ICS ... any tips??
Use set cpu and check on which frequencies the phone is running
And use BadAssBattery monitor app to see which app is sucking your battery
The huge battery drop is normal and happens on our phone as fuel gauge goes crazy

Try the following:
1. Wipe cache partition (and Dalvik cache) in recovery mode.
2. If that does not help, do a factory reset.
3. If that does not help, flash another ICS ROM. I made good experiences with XWLPD.
4. If that does not help either, examine with BetterBatteryStats (BBS) app what apps are preventing your phone from going into deep sleep.
Partial wakelocks is what you should look at.
Good luck !
I have the same issue with my phone. I tried factory reset and cache reset but my S2 is still running hot and drains battery in 4 hours after charging
I installed go power master and battery are being drained by the following apps
Bluetooth Test
Android System
Google Backup Transport
Keyboard.
I'm running ICS via Samsung Kies.
I9100DXLP7

I have recently flashed 4.1.2 Stock UK non brand and battery Life is horrendous, can you please share with me your mod? These are my details:
Like today, phone on at about 07.00am, now is 10.29 and im down at 35% which is ridiculous with Screen on 1h 29m > 74% as the biggest hog..."always scan for open wifi" was on and i recently disabled it..also, i keep wifi on all the time when i am at work. signal is 100% so shouldnt consume much??
recently tried to disable auto brightness, removed bloatware and few other things...is it the modem sucking too much or what??
4.1.2
Baseband : I9100XXKH3
Kernel : 3.0.31-Siyah-s2-v6.0b4+ [email protected] #57 SMP PREEMPT Wed Dec 26 06:52:48 PST 2012
Build Number : ZJ054K.I9100XWLSW
Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.
I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.
I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.
I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.
After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.
I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.
Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?
Thx in advance
edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
There are a couple things you can do:
1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible
2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood
3) Try a different ROM/Kernel combination, that sometimes helps
And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations
I HAD the same problem
Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!!
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.
Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.
Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.
How is the network signal where you are???, because it looks like it's realllllyyyyy bad.

Are you sure? Take a better look.
Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
I´ve been experiencing this problem for weeks. About signal I tried everything because:
- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)
- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.
- Some days ago I used another SIM which also have all bars.
I Don´t think there is a problem of the signal . Also in my other phone, and as you can see, Deep sleep is working fine.
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.
According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.
Also revised the voltage in the CPU and it is alright.
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,
but I flashed latest ICS from pccompanion with no other tweaks for some days and it
continued the same.
I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.
With a good kernel, undervolting, 2G... I can get to 15% 20% at night.
I've also switched batteries with other neo's and no difference.
Phone is 5 months old.
Not sure if it might come from the rooting process. If I understand right, the 0% issue
that some were having was more of hardware issue (or I'm completely wrong?) Then maybe
there is also something related?

0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).
Maybe the best thing you guys can do is send your phone to service.
I have a similar problem with my mt15:
when I buy my phone battery was ok. about two days with intensive social use, no gaming.
5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour
tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...
tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...
battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.
I thinked about battery fault. replaced my battery with a new genuine one. Same results.
If I remove the battery from phone, IT does not drain. 24h later battery is still 100%
So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"
Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.
I give up!
After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.
sorry about my creepy english
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.

about battery drain when phone is off
its not consuming your battery while its off
when you are turning the phone on
cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal
that's normal
i suppose its aroumd 3-5% of battery consume
im not gonna be at the same side with you
actually neo is a wonderful phone
i beated the score of sensation xe in antutu benchmark with it
just google it around the internet
there will be some fix mate..
Neo is not buggy at all maybe yours but not mine
this might work for you
i just found it
1-flash build 42 official rom on your device
2-root the rom (there are plenty of ways around internet)
3-flash this kernel via flashtool forum.xda-developers.com/attachment.php?attachmentid=780407&d=1321113977
4-now turn on the phone its gonna show 85% of battery
5-install this forum.xda-developers.com/attachment.php?attachmentid=897721&d=1329003275
6-plug the charger into your phone
7-from the menu of app select start full charge
its gonna take 3-3:30 to be full
may be you've seen it around web
i translated it from a persian forum
HIT THANKS IF I HELPED YOU
In my opinion, a phone broken by a software update/downgrade is buggy.
About battery draining while off, not all neo have this issue, but mine is not the only one.
On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%
Sent from my JJ's Hybrid MT15i
I had this problem too, even when the mobile was off, the battery was drained...
I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).
There is maybe a bad hardware series
I am using xperia p with stock JB (unrooted). I have to charge it twice a day without even any significant use. Sometimes battery just drains out by 10% or so with just an eye blink! Battery details showed that it's staying awake (or something is making it stay awake) while in sleep. Tried using BetterBatteryStats to find the draining app. But just 'kworker' and 'admsrv (or something like this)' seemed to be the only problems. Tried flashing and/or factory resetting 5 or 6 times and still no improvement. Please help.

i got this weird issue with my phone,its charged to 100%,but if i use it for more than 30min battery drops from 50,60% to 1% and in next 5sec phone shuts down.but if i play music and turn off my screen i can use it for hours.my phone is rooted and im using codename 9,2.3.4..please help
try other kernel if unlocked or try other ROM .. still same problem than conform it as battery problem
I have same kind of problem. As long as screen is off I get ~2%/h drain with wifi/3G and listening to music.
If I keep screen on it drops as much as 1%/minute even if it's just browsing web.
Tried various GB, ICS and JB roms.

Tried that more than a few times. Readings seem to be correct - voltages in each state seem to match too.
Tried with another battery from brother's Neo V - same problem.
It's closely tied with screen-on state.
So how can i fix this problem?
