Q: battery life

Hi everyone !
I'd like to hear your from you guys how you solved the battery life-problem, my phone is from 100%-0% in 6 hours. I'm looking for some information: like what I should do ? I see scripts to improve, but in order to complete the scripts I need to wipe my mobile and I dont like doing that.
Send me a reply . Thanks in advance !

Could this be moved to general?

Some common and layman methods are :
1. Switch to 2G mode. Use 3G mode manually when neccesary.
2. Try using an app like SetCPU to underclock your CPU.
3. Use lower brightness levels.
Besides these obvious cut-your-usage-type methods, all I can think of are UV scripts. You can also try different kernels like LordMod's, Unity, or RCMix, etc.. They offer measurable improvements in increasing battery life.

I use cynogenmod 7 the latest nightly and lordmods ue 8.5 Cfs kernel upgraded my radio to the second to latest version and now I'm getting crazy battery life, my last charge was 17 hrs ago and I still have 54%

if u don't want to try my settings u can try wiping ur battery stats which will collabrate your battery do this by charging to 100% then boot into clockwork recovery go to advance and you will see the option to wipe battery stat u should do this after flashing a new rom or kernel too

And I also use set CPU to under clock and use basically no CPU when my screen is off
Do some reaserch on the things we have mentioned and u will see better battery life in no time

Have you tried JuiceDefender? It will save a lot of battery by managing your data usage automatically. You should save about 4 to 6 hours.

What ROM/kernel are you using? Killersloth has a script for most of the popular kernels, try them out and it might solve your problem.

Which of those scripts would you advice me ?
Setcpu doesnt work for me, because im not rooted..

So I'm currently using Juice Defender,
I'm waiting for the new release of CM 9, then I have to figure out which (battery life-improving) script is compitable with it

Is this good battery life?

Help me out people ....i'm not sure if this is good or not. And is there anyway to improve it without juice defender

Screen on time?

Yeah..screen ontime would help. I usually last like 14 hours with 5 hours screen on time. I don't hold back since I have a spare on the external charger lol.

Its ok if you're a hard core user like having your face stuck on the screen all day long

You should give undervolting a shot if your kernel supports it. That helps with reducing power consumption while in use, while juice defender helps with reducing power consumption while not in use.

Heres an update no charging

That's not very good, even given the fact that you're on 4g the whole day.
You need something like JD. The 4g looks like it's killing you.

I dont know what's going on but I never had a battery drain like this...and I have the galaxy nexus extended battery in!!!
Sent from my SGH-T989 using xda premium

yeah that's rather bad. i would put on average that our phone would last 4+ hours display on screen without the use of JD and other stuff.
I would say voice uses more battery than display on.. but barely... like 1.3 : 1 ratio in use voice : display.
Your android system looks a bit high too. Maybe a fresh wipe and install would help things.

Dude.. 22hrs? I need your current setup lol that's a decent battery life i would be happy with that!

it's not your signal, your signal is mostly green when in use. and as you can see the cell standby and stuff is a small %. but yeah try a different rom.

What ROM are you using though ? I'm paradigm , I'm thinking of trying stock idk yet xD
Sent from my Galaxy Nexus using xda app-developers app

Kernel or rogue app.

I have tried so many kernels and roms including cm10, aokp and slimbean but in all of them the same 'media' process is taking 40 to 50% of my battery even in standby. Is it some app that might be responsible for this drain?
Sent from my Galaxy Nexus using xda premium

Most likely an app.

Can you recommend me the best way to find out which app is it? I have uninstalled 80 apps and still the problem persists. There are only 40 apps on my phone now, mostly trusted ones like viber whatsapp etc so kindly recommend me the best possible way to find out which app is responsible for the drain
thanks

I was reading in another thread that the viber app was causing battery drain for some people. I will see if I can find the thread.

I'm seriously confused now ...i have installed paradigm rom and also slimbean again with stock apps only and still the problem persists ...is it possible that some of the files in my internal storage might be being used up by GAPPS constantly and causing the drain? :S

Use an app called Better Battery Stats - this app will help you determine which app may be keeping the phone awake.

I was having some pretty abysmal battery life with google now enabled,but since I've disabled it I've noticed a upswing in battery life.

Kernel controls and battery life issues.

For the last few months Ive been using the thread located here http://forum.xda-developers.com/showthread.php?t=1599025 while this does great help to my phone I still have a hard time keeping a decent charge. Lately Ive found that It takes an incredibly long time to charge however, it seems less time for it to go dead. What am I doing wrong?

hows your usage? post your battery stats and screen on time from tbe phones main settings, battery.

Now this is just standby time...this is including minimal usage

Screen on time sir.
And screw the 4G. The max screen on time i see for people using 4G is 2h+, a GSM gnex can normally achieve 3h-4h+.

All this does is wipe the battery stats in Android, nothing to do with the battery, the battery have it's own meter..

So...getting back on topic, what should I do

Red light... IR or Proximity Sensor?

I have an AT&T Galaxy S3, the I747, which is currently running the 5/10 build of PAC-Man, the 5/9 build of the KT747 kernel, and task650's 5/8 gapps. I dropped it about a month and a half ago, shattered the screen, and had to replace it. A quirk to this is that I had to replace it with a screen from a Sprint Galaxy S3, the L710. After I replaced the screen, on Friday, I flashed to the stuff I'm running right now. Yesterday (Sunday), I noticed that the sensor directly to the right of the front-facing speaker is lit up with a very faint red color at all times while my phone is on. I have done a little searching, and from what I can find, everyone is attributing this to Viber, which I don't use.
It's this one:

My proximity sensor and light sensor are working fine still, but my main concerns are battery life and longevity. Is this light being on going to either hurt my sensor in the long run or create unnecessary drain on my battery, and if either is the case, what do I do about it?

I noticed mine was on one day while i was in bed, just rebooted and haven't had it since. I don't see why it would need to read data from the proximity sensor unless your on a call or so it shouldn't drain battery . if your in the SMS app then it might be using it for direct dial but I'm not sure if you have that feature in pacman

I don't have that feature, but it doesn't matter which app I'm in, or even if my screen is on or not. The red light is on all the time if my phone is on at all.

Any ideas for a probable culprit?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Try a program called greenify. It will tell you which programs are causing wake locks and what is using the most battery.

Hi, I used to have Viber installed, until I noticed that dot I didn't relate it. It made me panic so I went through my apps 1 by 1 and found viber to be the one keeping it always on even when its not running. If you don't have Viber, go to your installed apps page, go to downloaded tab and force close each one. If the red dot is persistent then its another app. Keep going until its gone and you'll find the culprit.
Have a good day.
