battery drain

hi i have the usual problem with my samsung galaxy S i9003: my battery drains extremely quickly. on the battery usage it shows that the display is what is draining my battry the most, but the problem is, it is on its lowest. i just don't know what to do, i wiped the battery stats, i downloaded lots of programs to save battery, i removed the google backup transport apk, i don't use wifi, 3g, gps, bluetooth, i don't play games, i really don't know what else to do.
so please, help me.
i bought the phone from another person, so it's been already used.
i'm on gingerbread DDLF2, i'm rooted and have already tried a few roms but had the same problem, if you know of good, stable, smooth and for daily use rom please let me know.
ps: my phone doesn't show real battery stats, what i mean is, when the phone is on 30% it just shuts off, and when i plug it and turn it on, it shows 0%. it has happened since the day i got it.
ps2: i don't know if this matters but, i soft-bricked my phone like two weeks ago trying to restore the stock rom from a remics rom, and flashed the stock rom to get it back.
the battery drain problem has been there since before but i just wanted to put it out there to see if it helps.

can you tell me for how many hours your battery lasts after fully charged.
battery usage also depends on cpu usage ( like if u have set your processor limits to high ) or may be because you have lots of apps running in the background. you can try installing watchdog application to trace whose eating up your battery

I experienced battery drain too on GB ROM. I guess that newer apps are using android functions that are not coded very efficiently on GB.
I was surprised that battery life got much better after flashin to 4.4 kitkat. If you want to give it a try, I definitely recommend trying out flashing your device and see whether battery life improves

yes.... can try out different rom or some other kernels too. and try changing processor to some battery friendly mode like " conservative " or tweak the default processor to save battery.
and try out greenify app if you are not using. @luligorla

my battery last for about three or four hours if not less. i'll try downloading that app, but anyway the problem here is that in battery usage in shows that display is what is spending the battery the most, when it is on its lowest, i just don't get it.

i'm rooted, indeed, but it seems i'm not finding that application or if i have to download one. i downloaded whatdog and the only alert i got was about the gallery using the cpu.
what i'm worried about is that the display is literally on 0%, isn't it weird?
i tried flashing 2 different roms and with both the battery drained just the same. if you know about any stable, smooth and for daily use rom please let me know!

Need recommendation for KitKat rom

Hi,
Every KitKat Rom that I tried was affected by some kind of battery draining bug which has to do sth with Google Play services. Can you recommend a fix which works by doing it a single time? Uninstalling/stopping Google play services fixes the problem for a few hours only.
However, I would prefer a rom which is not affected By the bug out of the box.

I'm testing Racpu_ cm11s. Was having Google Play service wakelock, but learned somewhere on Oneplus forum about this: Install Disable Service from play store, switch to system tab, check SystemUpdateService. That somehow eliminates the wakelock. Today is 2nd cycle, 4hr screen on for youtube netflix under wifi, still rocking 48% of battery.

Cool, Ty, didn't know about this Bugfix,will try it. Why are you testing kitkat Roms in 2016?

Please tell me about your (major) findings about your research. How do you log and observe your the battery consumption? Which configs for sync, screen-of-gestures, brightness ?
I can share my findings also, if you want.

Sure. I wouldn't call mine "research" tho haha
Now I'm on slimsaber kk build, about the same SOT, feels slightly smoother than cm11s maybe.
Did my trick for the battery drain, but now Google Play services FC unless I set location to device only, oh well...opengapps btw.

Since I opened this thread, I am on Karbon kitkat which seems to be a fork of Slimxxxx
Fortunately, I did not get an always active bug until now, so I didn't try your Bugfix.
How much SoT do you get with your roms and which configuration.?
Most times I get 4 hours with the following config
- brightness static 50%
- sync, tapToWake and offscreen gestures off ( just in case...)
With following usage profile:
- no 3d
- no video (out of short clips)
- chrome, messenger, quora, Google news
- telephone 45min
- 75% WiFi, 25% 3G

With Racpu's cm11s and Slimsaber KK build, I didn't get to use the battery all the way to like 1%, but I already got 5hr SOT before that. Here are more details.
Racpu's:
- auto brightness
- youtube and netflix a lot, some xda and chrome, abou 30min phone call
- always on wifi
- greenify in exposed mode
Slimsaber KK:
- auto brightness
- 3hr LTE, rest on wifi
- about 2hrs of youtube and netflix
- 40min navigation with google maps
- a few camera shots
Don't think this is scientific enough, but hope it gives some idea on my usage.

YouTube, video in general does really really impact SOT measurements. You get about 1,5 to 1,8 times more, I measured it a lot. Navigation is the other extreme : 3d, GPS and most times a high brightness because you are outside (on daylight)

Ah OK, that seems right. I didn't do such detailed research
Now I'm leaning towards what most people say: Battery life depends on how you use the phone.
Also, I think OPO has an amazing developer community and all roms are of high quality and yet retain their own unique qualities like functions etc.

Best Rom\Kernel Combo for SOT and Performance?! POST PICS!

Hey guys … we've had quite a bit of development in a very short amount of time since release. There are some very talented developers out there and a dedicated number of people making our already great phone even better.
So, I was curious to see at this point what Rom\Kernel Combo everybody is running to get the most out of the battery while maintaining performance!
Sound off on which rom\kernel combo you're using and post battery life screenshots if you have them!
Thank you to the developers that make this happen, we couldn't have gotten here without you!

I guess there is only one stable rom xXx

SOT varies and depends on your usage.

Xxx+cleanslate

If you want a balanced kernel with a really good battery life, you should go with franco kernel. I achieved very good stand by and screen on time, even on the currently battrry-buggy OxygenOS 5.1.8. And if you want a light customizable ROM with quiet a few goodies, go with Renovate 3.2.

Is that stock options with Franco?

If I pick up my phone and use it all day in bed when I'm under the weather or when I'm home for the day with nothing to do I can get 7 hours of screen on time with constant usage at half brightness. When I am at work and have the phone with me and do a little gps etc I can get about 6 hours. It all depends on your usage and also your cell signal. The worse your signal is the faster it drains the battery. The more GPS you use the faster your battery dies. It doesn't matter which kernel I am running, (I'm currently on stock 5.1.8 with Magisk, Xposed & ElementalX) battery life is pretty much the same.

if you won't stop to believe that rom and kernel are responsible for SOT and standby drain you will never be able to 99.9 control and manage your battery usage.
it's all in user space as long as there is no know battery hog (know bug) in either rom or kernel.

Android P Beta Battery Life?

Hey guys.
I've done a quick search from the XDA app and I'm not really able to find any specific details on this topic.
Currently running 5.1.9 with xXx rom and Franco Kernel, which means I'm getting spoilt for battery life with around 7+ hrs SOT!
The info that I've been able to find on Android P for OP6 generally seems to indicate around 2.5hrs SOT.
For anyone using the latest beta, can you please share your battery life? Whether it be screenshots or general experience?
The latest beta seems to be pretty stable, but this is the last thing that's stopping me from taking the plunge!
Also, from the research that I've done, custom kernels seem to work with the beta but it breaks wifi? Is this true or am I way off?
Thanks in advance

For me it's not as good as 5.1.9 with Franco or Flash kernel, but not as bad as 2.5hrs SOT, more like 5 or 6 but with a worse idle drain. I'm with xXx module, viper and I spend way too much time on Youtube...
But if I was you, I'd wait for the next preview since Google pushed the last one beta 10 days ago.

The battery life is bad on p compared to 5.1.9
.. Been running it for almost 2 weeks here. I get around 4-5 hours on p while I used to get around 6-7 on oreo

Oh true I didn't think about the new one.
In saying that I'm quiet impatient ?
5 or 6 is way better than I was expecting though!

Yeah I don't have an exact comparison between 5.1.9 and DP4 beta 3, but i would say it's almost the same.
Don't feel a big difference.

Why not use beta? It's fine for me. Literally everyone say bad battery life after an update. Perhaps give it some time.
