Hey I have noticed lately my battery is taking around 2+ hours to recharge and I get Max 2 hours screen time from a 100 percent charge.
This is with display brightness at minimum around 5-10 minutes call time and ready mostly chrome and Facebook. I have also undervolted turned all sync times to as low as possible and have wifi gps and everything set to off.
My mate with the same phone and ROM/kernel/theme gets 3 hours easy and his brightness and all settings including sync are default.
I have tried the reset battery(no change) and installed better battery saver but everything seems fine?
I am running aokp M4, Franco nightly 97 and black exodus theme.
Any guidance appreciated.

Hi everyone!
As I am a new member I am not allowed to post to the Development thread ("[ROM-GingerBread] Ginger Villain 0.9 Camcorder working (24-01)") to ask my question.
I hope this is the right position for my question...
I flashed to "Ginger Villain 0.9" yesterday in the afternoon, unplugged my charger having a fully charged device close to midnight.
Nine hours later the battery was down to 51%. This was during night, where I was not using the device.
Background sync and WiFi was on, even if the WiFi-network is off in the night.
I did not switch off WiFi with the original Sense-ROM (Froyo) or with the LeeDroid (2.3d) I used before, but I had to charge the device all 2-3 days - using it more than I did today.
Coming to the questions:
Is this fast discharging only a problem on my device, or do others have this as well?
What could be the reason for this?
Hope you can help me.
I've had GV0.9 on for a few days and not noticed any real difference in battery life. Before that I was on LeeDroid, before that stock HTC.
First day on GV I got about 39 hours. Pretty light use but that does include some wifi, and GPS with a running app. Pretty much exactly what I was getting before.
Today it's showing about 60% charged after 15 hours with again some browsing, music playback and general use.
What radio and kernel do you have? Also on the about phone - battery use screen where does most of the usage come from?
Edited to add
Go into wireless and networks, wifi settings, menu and see if you have wifi sleep policy set to 'never' - this is a known battery drain issue

so if it is set to never it will drain your battery? so i should set it too the 15 minute option to conserve battery?
Night #2: Better, but still bad.
WiFi ist set to disconnect while screen is switched off.
I did not notice this option (Menu/Advanced) before, thanks for this hint.
Since the last unplugging from the charger the device discharged from 95% to 38% right now, in a time span of 14 hours.
Around 30min of this I was checking e-mails or browsing - all via mobile network.
WiFi was switched off the last night, I lost 27% in 8 hours.
Which e-Mail clients are you using?
I used the HTC-Sense mail with the stock ROM and LeeDroid, now I am using K-9 mail. Collecting mails is set to a 30min cycle. With K-9 Push (IMAP) is active, but I don't remind what was set with Push under Sense-Mail.
What are your settings?
Sorry, confused you there. You need to set the wifi sleep policy to 'never'. Anything else will cause battery drain.
Se if you have 100% cpu with quick system info!
Do you sync your Music ????

Thanks, setting WiFi sleep policy to "never" saved battery a lot!
I set this option and charged the phone to 100%.
It lost only 41% in 44 hours.
With WiFi on, even at night. As well with mobile data connection, IMAP Push, sending of 3 SMS and one 2-3 Minutes phone call.
No, I don't sync any music.
These WiFi-options are doing the exact opposite of what they are supposed to do?!
Hi
I thought I'd report on my testing with CPUspy. I've had the Nexus for two weeks now, drained the battery completely from a full charge about 4 to 5 times.
CPUspy is stating that the phone is in deep sleep 95% of the time with 350mhz 3% of the time and all other frequencies at 0% for some reason.
I'm running stock with data plan always off, bluetooth always off and WiFi only twice per week for about 30 minutes + the phone never uses 3G, only 2G networks. I've not made too many calls (3 calls) and about 11 texts during the two week period. I've installed two 2D games, battery monitor widget and Facebook app.
Today I installed Juice Defender (free version) but I honestly think that it wont help at all since my settings are already very tight/restricted. I always make sure no apps are running in the background.
With light use (4 text messages, zero phone calls and 18 minutes using WiFi, phone only in 2G mode and playing 20 minutes of games) the battery depletes about 28%.
My results:
Android OS is using between 28% and 68% of the battery
Phone idle is around 38%
Cell Standby is around 14%.
What is the difference between phone idle and cell standby? How does CPUspy tell me that the phone is 95% in deep sleep yet it drains so heavily with light use and without any use at all about 4% per hour? Is CPUspy a good program to use with ICS?
I thought my findings would be of assistance to some of you.
My phone:
- stock rom .62
- latest doomkernel (v10)
-.36 baseband
I removed all bloat, have 310mb internal memory free (ran supercharger)
I configured setcpu 806max, 134min, smartass governor and screen off profile 365max 134min
When the screen is off, i don't have the drain. It was at 74% when i went to sleep, when i got up about 9 hours later it was STILL at 74%, so there's practically no drain when the screen is off which is really nice.
But when the screen is on, the drain is immense. I have about 1% drain every 3min when the screen is on. It's on max brightness. I just left the screen on continuously for about 3 hours, and it has gone from 70% to 14% in just those 3 hours leaving the screen on (just leaving the screen on, doing nothing else on the phone).
Is this normal? If not, can somebody tell me how i can find out what is causing this drain? I'm happy about the drain (which is zero to none) when the screen is off though...
you are doing everything ,however if you are using high powered apps like Muffin Knight/Experiment /etc they will drain battery fast under 3 hours
I'm not running any apps besides the standard+setcpu
Display needs to be lowered. Make it Auto.
Turn Wifi off. If you don't need it, it's just awful to have it on because it's always searching & searching and wasting battery.
Also, use this app that I'll link below. It has something called a "Smart Power-saving" function where all 2/3/4G and WiFi will shut off when your battery is 20% or lower, thus leaving only Phone and SMS activated, and there's an option for root users where the cpu will underclock when the screen is locked! It DEFINITELY helps!
The market page is all in Chinese, but the app is in English.

Hi everyone as you can tell I'm a noob, so please just take it easy on me thanks! So here is the problem I have so recently I installed DARTHSTALKER V8 on my Galaxy S3 T999 and my battery life was like 4 hours so I was confused because people were getting like 16 hours. So what I did was I downloaded a new kernel called "LJA TWiz-JB-OC" v1.1c. So it increased my battery life to 5 hours on like a 50% battery. So I was wondering like what settings can I use on this kernel or what other kernel could get me this kind of battery life of 16 hours or more. Also, I found that someone said, " this kernel works flawlessly on darthstaker v8. 1350-192, ondemand, sio! UV -75" but I don't know how to set this kind of stuff.
Please Help Thanks!
Download set cpu, from there you can adjust, frequency clocks, governor, scheduler, undervolt, turn all animation or window transitions to 0.5x in developer options, turn off battery saver, email, facebook etc make them sync every hour or two, reduce brightness to 40-50%. Auto dim screen or auto lock after 30secs or 1 minute.
When I'm at work my wi-fi is turned on all the time as there is no signal in the basement i get 12-14 hours on my battery.
POWERED by FROSTY!
I'm having battery issues. I am normally getting 2 hours SOT maximum, which reduced to 1h30 over time. I did a factory reset (still on stock android) and flashed ElementalX kernel to downclock the cpu/gpu, to hopefully save some juice, but it didn't change much. It looks like my phone is never going to sleep or doze and is depleting battery at a steady rate while not in use.
Here is a screenshot album: imgur.com/a/dezhr
Some **** won't let phone enter Doze, you can see Awake (screen off) line in Better Battery Stats. It means, that although screen is off, phone is still fully awake - probably an app syncing in background.
IMHO it's Google Play, not sure though. Try reflashing current ROM build and newer GApps, while keeping all data.
It looks like it was Facebook Messenger that was running constantly in the background.. Once I killed the app, the power stopped dropping. Also it seems that turning off the wifi helped a bit too (since there was no wifi available).
