battery time just fell off

without doing anything new my battery time just droped off the face of the earth.. its down about 75%. i was getting a full day mixed use now all of a suden im getting 6-8 hours with just a few phone calls.
my awake time is at 16%
I havent done anything new that i can think of.
im using (and have been for awhile) the mugen 1800 extended battery.
trying to think what might be doing it and cant come up with anything i havnt found in the forums already.

you probably downloaded some app that is running in the background continuously. check with a task manager to see what's running, and then try uninstalling some recent apps to test it out.

thats what i was thinking but i cant find anything new running with the task manager

Could just be a bad battery? I'm having same problem, maybe worse with stock battery. I went from 100% down to 15 in like 5 hours just reading my RSS feeds every hour or so. I think I may have fried my battery using it to tether for excessively long periods.
You're not using your phone to tether are you?

Mine is way down this week too. Initially I thought it was Swype, but not so sure anymore because no other users are reporting problems.

Are you using Modaco's rom and kernel ? or any new kernel for that matter? Ever since I switched kernels my battery hasn't made it through the day.

I'm using gbhil's custom kernel and seeing BETTER battery life when used with setCPU (using ondemand setting with 'standby/sleep' profile turned on, and set to 160/480).

No I'm not.. Turned a few more newer apps off and still no good today.. I was at 5% batt left after 9 hours with about 10 minutes web browsing (not wifi) 4 or 5 text messages and about 45 minutes talk time. That's down about 90% from were I was a week ago .

I managed to narrow my problem down to the Taskiller widget. Removed the widget (still running the app full time) and all is well.

Last night I rolled back to before I used a custom Kernel. I rather battery life over speed. I need my phone to last from 6am to at the very least 7pm. I think once people get over the performance boost, we'll see a lot more posts relating to battery issues.

might be that too, i hope not as i love that keyboard. just having it installed shouldn't drain the battery, should it? im on day 2 with the custom kernel and i too noticed more battery drain. at 1pm my hero was fully charged. i only played a bit with the phone and made two short calls and it's down to 86% already at 4pm. i want to roll back but i do like the speed of the new kernel. ill see how it does tonight.

Yeah going back to regular input sucks. Swype was only some leaked beta version, we don't really have right to complain; however, I bet their end product will be much better. I just hope they'll release it as an app and not as part of custom Android phone so we can get it sooner.

figured I woud resurect this thread rather than start a new one.
yesterday I decided to RUU my phone to pull the completely stock apks out of it. after I did that I restored my backup of fresh 1.1 with gbhils kernel and now I am at 90% awake time spare parts shows that "android system" as something keeping it awake. any suggestions on what this could be? could it have something to do with restoring the back up with the kernel over stock without a wipe?

SE Stock Rom Advantage!

Hello All,
I noticed there are a lot of posts regarding Battery Usage & Optimization...
I tried many many combinations of custom roms, basebands and kernels and I always face the same battery problem especially when 3G/MobileData is switched on.
I admit that Sony Ericsson gave us a ****ty stock rom with poor kernel however It's still the best rom in managing battery usage.
I made a small comparison on Stock rom VS Custom roms with 3G/MobileData left switched-on and I found the following:
Custom rom(s): battery drain down very fast it goes for 100% to 1% in less than 8 hours (normal apps installed)
Stock rom: battery lasts for 2-3 days with normal daily phone usage (same apps installed as i did in custom rom)
Please share your opinions.
Thanks,
Ayman

I don't agree at all...
Custom roms can have just as good, if not better, battery life.

I personally think this was a good idea. Nice post and info. Just curious, how long did you do this study with the data you got?

hey guys, i too have this issue, i dnt know if its device specific. ive had the phone since march(2010) last year and have been modifying it with the great mods that the devs hav given us. everytime i install a custom rom i just get unusual battery drain, like yesterday, i followed instructions to the letter and installed tripnravers miuifroyo 1.0.8 and i lost 10% battery in like 20 minutes n ive hardly used it :-(. so nowadays i stick wiv a modified stock 2.1(ewjet to b exact). im gna buy a new battery and see if i get the same results. i really wna use a custom(2.2+)rom but the battery problems are really putting me off, theres so many people out der that arent really having ny battery drain whcih jus dus my head

Thanks Voelker BTW this is my first Thread in XDA, I used to use SE 2.1 stock rom till the first stable Froyo custom rom came out. I switched to Froyo then I started to notice this around 4 months ago and I tried many combination and a lot of optimizations to find out the best one although Stock rom was always better.
@fiscidtox:
I love Foryo and GB much much more than Eclair I currently on CM6 v6 Wolfbreak
Could you please tell me how the battery lasts on your custom rom while MobileData is left switched-on?
Thanks,
Ayman

I get a full day..
If you mean stock with no tweaks then maybe it would last longer, but a lot of that would be not having jit enabled...

You must be doing something wrong!
10% in 20 mins isn't normal.
I'm sure if you left it settle this would rectify itself though.

I think the biggest advantage of the stock kernel so far is stability, but the ongoing development for the custom kernel is sucessful to implement some problems such as battery drain caused by unability to go into deep sleep etc..

I never understood needing more than 24 hours on a charge. Charge it while you're sleeping you wont be using it then anyway.

Even if you like the 2.1 Stock ROM for any reason (Stability,Battery,etc) and don't like all these awesome 2.2 and 2.3, you should at least use Eric's JET ROM which is based on the original ROM has no stability issues and has faaaaar better battery life.
But seriously, I`m using Custom ROMs since the first 2.2 ROM by Z and never even cared to get back to the stock ROM.

When I use Wifi custom roms have almost the same battery life as the stock rom. But since I can't connect to wifi at work on any custom rom, im forced to use 3g.. and I need to charge my phone twice a day with almost no usage.

Let it settle for at least two days to see improvement.
Your battery needs to adjust, much like letting your phone build a cache, in order to really see how the rom will effect anything.

Im using the stock rom and my battery lasts a maximum of 2 days with this tweaks: http://forum.xda-developers.com/showthread.php?t=934486
I dont use 3g at all and i use wifi sometimes (session lasts only 10 mins or so)
Brightness is set to "middle" also

Sorry dont agree..
I use wolfbreaks latest rom with the undervolt module.
Juice defender only enables my wifi when i am at home...all other times i have data on with facebook sync.
I now get the same battery life as i did on stock 2.1
Currently I have been unplugged for 1day and 12 hours and I am still at 38%.

3g is useful incase of using Apps such as viber, whatsapp, IM and Gmail as it makes you online and reachable all of the day.

Villainrom 1.4 Rocks !!

Hi All,
This is my first ever post on this forum although I have learnt a lot reading through various posts which was immensly helpful. I have run numerous ROMs on my Samsung Galaxy s2 and finally settled on Villainrom 1.4 which I must say ROCKS especially in terms of Battery Life which was a main concern for me! Earlier-with stock ROm and also with other ROMS (Litening, Cognition, Batista) battery life was getting better but it hit the pinnacle with VillainRom 1.4.
For an idea, I used to get 1 full day of juice with moderate calls, no wifi, few smses, some market downloads/ updates, 2 mail accounts set to sync every 30 minutes, some gaming and some video playback.
Now with the same usage I get close to 2 full days. Thats a remarkable improvement. Thanks to all the ROM developers especially VillainRom which made me tweak my S2 to the max.
Cheers
Sunny

I ran into nothing but problems with villian rom. Im pretty sure 99% of that was mods I was trying add. But I lost my hardware buttons when using it.
But battery life was really good. I always start roms with 100% and let them discharge. Every device is different and happy ur enjoying it.

Your battery will also have had a few more charges and be holding a charge for longer.

i agree i had troubles getting it on but plusar helped me and it worked and the battery life has improved loads! well done to him I say

Yuuuuup pulser rocks!! . Been on ere since 1.1 .

Yes, a battery needs some charges/cycles to be running at full performance. Maybe when you tried the other roms this wasn't the case

I'm very happy with Litenin' ROM v 1.5 battery life.
I use to have 1,5-2 days of moderate use.

Battery drain fixed on my Vibrant!!!

After flashing numerous ICS ROMS lately, I always seemed to have one major complaint. No matter which on I tried my Battery wouldnt seem to last more than 8 hours or so. Well, so far it's gone down only 6% in the last 6 hours with moderate use. here's what I've done (on Doc's Master ICS v5 Final, icyGlitch v14 b5).
***if anyone already has this listed somewhere, I apologize. I tried to find a post telling what to change and i couldnt so this is what i came up with***
1. set min/max cpu to 400/1000
2. use glichassV2 scaling gov
3. ns tools: active scheduler set to fiops
And I must say, Doc's Master V5 has easily got to be the BEST all-round ROM I've tried BY FAR!!! Vibranturk has damn near perfected this stuff.

Don't know if this is going to help, but appreciate you posting it. I have decent life on AOKP Build 26 with icy Glitch v14b5 with CPU set to 100/1300, Glitchassv2, default scheduler, and the 1800mAh battery. But if this helps squeeze a little more out, then all the better. Right now I get about 12 hours with moderate usage.
Sent from my rough sketch of a Vibrant on a brick.

I'm running TeamHacksung's build 16 and the main thing I've done for battery life is to customize the screen brightness levels. I had battery drain issues on it the first time I flashed, but I think it was because something I had done. I odin'd back to stock and reflashed CM7 then the TH 16, everything has been really smooth. I'll have to try out the changes you mention here to see how it goes... I'd love to be able to get the same or better battery life and more performance.

well, i made it to 12 hours. but about a solid hour and a half of that was playing Need for Speed Hot Pursuit so i imagine w/o that i couldve got quite a bit more life out the charge.
I had to turn the deep idle off when it came time to charge or it wouldnt charge correctly. and, for some reason it keeps saying that its 100% charged after just a short time. after a reboot the real percentage shows up.

You guys are on GLITCH kernel im guessing to get Glitchass v2 governor?
I shall try this for Euphoria today.

Can't believe i'm saying this but it truly does work. Usually after school my battery would go to a crawl to about 20% today it stayed up about 50% REALLY fantastic standby life.
Thanks OP

x66, if you want to get even better battery life, go into the display settings, in the Backlight settings, and you should be able to edit the 'Other Levels'... Bring those down a bit if you haven't already and you'll get even better battery life as you won't be using as much juice on your screen. Has worked out really well for me.

I am on AOKP M4 and I cannot find that setting... but its cool i'm getting amazing standby life.

Ok, so i tried the op's settings, and i unplugged 3 hours ago, and I'm still at 100%.... I dunno if it's a battery reading bug, but if it's not...wow!
Also, since doing this tweak, i got an upload speed boost....i dunno if it's related..

Edit...it was a reading bug....it was a battery reading bug...i was actually down to 50....but the speed tests....still dunno how i got such high upload speeds.

Best battery life JB rom

Guys, as I am truly annoyed by the fact stock JB is draining like hell, I would like to know the best rom available now. If any of you have good experience with a particular rom let me know

Try Adam's ROM I'm getting similar battery life as in ics
Sent from my Nexus S using Tapatalk 2

It's most likely not a ROM issue. I tried Adams and CM10 and had similar battery life. Make sure you turn off google now (just the cards that need to know your location constantly). It might also be that your update didn't go that well, so you might try a factory reset. It could also be a misbehaving app, so when you do a factory reset, maybe test the ROM before restoring/reinstalling your apps. Also, the more information you give us the better we can help. Good luck!

Thanks for the info. I installed the stock factory image 4.0.4 and then waited for the official OTA. I updated and all works well, but I get around 15 hrs on a full charge with some Whatsapp and Facebook use. When I use it more intense with more screentime the battery drains the most. I think a factory reset wont give me more battery life then this, but I know my drain was not so big while I was on ICS.

By the way, which one is the most stable; CW10 (That chocolate river one??) or Jellybelly?

Sounds weird. But also keep in mind that there are still some apps that don't cope very well with JB, and Facebook has never been Androids best friend . But it doesn't make sense that it's only during screen on, most people report issues related to google now and apps doing **** in the background. If you want to switch ROM anyways, I suggest you use Adams Jellybelly, it's mostly stock (less features means less that can go wrong) and it includes thalamus kernel, which is IMHO the best JB kernel at the moment. I do not recommend any CM10 based ROMs if you're after stability. I assume you checked your battery stats and didn't find anything?
Edit: Chocolate river was abandoned when official OTA came afaik, so definitely Jellybelly . Make sure you do a full wipe though, if something's wrong dirty flashing isn't worth it.

Sounds good to me. Downloading Jellybelly now. I checked my battery stats and didn't find anywhing weird. I dont have much apps installed so there is not much that could give issues. When I leave my screen off (at night or while working) the battery life is not that bad. It's weird, but JB is still very fresh and new, so I'll just try some other roms =)

Agreed jelly belly provides the best performance, stability, and battery life

I am currently on JellyBelly and the battery life is definitely not better than stock for me. Battery drains like crazy when idling.
BUT, I do have Google Now activated. So really make sure to deactivate if you do not need it.

IMO all ROMs should give similar battery life.

Even with Google now turned on the battery should last some time. Do You get the same time as with ICS when it's deactivated? If not, something's borked .

Even if the battery life isnthe same with Jellybelly, the performance is great!
