Battery drain after installing MIUI

Hi, I recently installed MIUI 3 and seem to be getting some problems with battery life.
What I've done so far:-
-Installed MIUI 3 with the SpeedMod kernal (as directed in the manual). Battery life dropped to 12hrs
-Reset battery stats, no change
-Installed MIUI 3.3. Battery went back up to ~30hrs
I thought 3.3 fixed it but after a day the battery life dropped by half. After another day it dropped by half again. Now it's only lasting 6hrs, and when on charge it doesn't reach 100% charged but stays at 98% even overnight.
What is going on with this thing?

Half of MIUI threads is about battery drain. There is no solution until now.

They're all like 1 year old. The battery was supposedly fixed in the latest release, and I know someone with the same phone, using MIUI, and they don't have this problem.
I think it might be something to do with the speedmod kernel. I don't know anything about the compatibility of kernels and MIUI so i just followed the instructions in the manual and used speedmod

I don't really know what's going on... in my phone the battery lasts for around 60 hours, maybe more, whatever rom/kernel I've used...
I've been using all of galnet's muiu and still have to find a battery issue. In my particular case, I don't use GPS, so it's off all the time. I don't think that's the issue though...

It's a known issue of CM7/MIUI.
no solution at the moment

Sorry but what is CM7?
And if there's no solution, how can someone with the same model phone not have the same issue?...

MIUI has battery problem and its not solved. If you disable data, gps, sync...
it saves some.

I will look into that and try to help!

The 5th thread you have posted this reply to in the last 2 hours?! Why?!

So everyone using MIUI puts up with a battery only lasting 6 hours and my friend is lying to me? >_>
btw disabling data doesn't make that much difference.

I think that this is as much a cm7 thing, as anything else, and most people just tweak and seek til they find a combination of things that work, so worth looking in rhe relevant threads and reading back

Well for anyone interested I found the problem. I tried flashing with the latest SpeedMod kernel, phone wouldn't boot, and I had to reflash the entire bootloader with MIUI's modified Froyo
Now the problem I noticed when I went to install MIUI.. the zip on my phone was 2.2 instead of 3.2.
NFI how I ended up with that outdated version! So the latest 3.3 seems to have fixed it now. Phone has been on for almost 20 hours and only dropped 30% in battery. That's more like it.
Although this did happen the first time, it seemed OK and then kept dropping by half capacity each day.. But if I really was somehow using 2.2 then hopefully that's all it was

I found out yesterday that my phone doesnt really go idle because of some google process waking my phone notoriously, and probably thats why it uses more battery. I also have very week signal (only 3g) which makes my phone use more battery than normal, but on non cm7 roms i made it one day with no problem. Right now I'm on galnet's miui and this is really fantastic rom, but battery wont last one day in my case. So the idle problem is the case i think... yesterday I closed gapps process before i went to sleep, and my phone was sleeping nicely too This process is caused by android market, and miui doesnt close it up. I also freezed gmaps - someone in galnets thread said it also drains battery. Well I'll see in few days how the battery will behave.

Also Battery Calibration.apk (can be found in market) works to calibrate your battery properly.

56hrs without recharging, 22% battery still remaining. So clearly it's not a problem with CM or MIUI any more

I have exactly the same problem.. tried the battery callibration app..also tried the wipe battery stats article.. i ve finished recharging 100% 2hours ago... now my phone is 55%..no gps no games.. 2 phone calls for 2min each.. i love the rom and hate the battery
sgs i9000..miui v4 with its kernel

[Q] Having fast batt drain after installed Oversome 3.1.1

Dear all,
I just upgraded my tab into overcome 3.1 from my initial GB 2.3 . The reason why i started to discover some issue on my batt usage is within 2hrs it will take off 20% of my batt when i fully charged in the morning.
After which i check on my application - batt use - it show "display" is at 92% on the top and android system is at 2% at the bottom. Whereby when i use GB 2.3 rom, it will show andoid system is at 80~90% and display is at the bottom of 3%.
(Note: i have even set my display to the lowest and set it to Auto mode, some of the un use application i also shut down)
I have started to think should i change back to GB 2.3 or is there any brother outside can advise what should i do to change this situation. Hope someone can help me on this ..... Thanks in advance.

dear all, after further confirmed, my colleagues also having the same problem as my, I was wonder is there a bug in this version as em not sure why the consumption of the battery was so high after installing overcome 3.1

First of all, old ROM had a bug, battery usage was displayed wrong. That is fixed, but they are now working on R2 version of kernel (Reverted lowmemkiller change which may have been blocking kswapd0 from sleeping, resulting in battery leakage).
This last kernel has a new ROM as it's base, so you have to install new ROM first and then full wipe version of kernel.

Good to hear I am not the only one.
Hermes was an awesome rom concerning battery stamina. I hope the guys from Overcome will make this R2 release just as good.

thanks for your quick response.

The latest version of the overcome kernel is pretty good on battery life for me.. the only thing that seems to be wrong is the reported charge level against the battery display level..
Even after calibration its still way off (20%)..

i think you need to perform a "wipe on batt" in cwm maybe can help. Anyway i also discover that my tap below 4 buttons occasionally the light will be blinking on and off during at the standby mode, i belived this also can cus some batt drain off too. Anyway, most of the people are concerning about batt duration especially devise such as non-detachable batt. For me, i use my tap outside most of the time especially during business trip hangging in the train station or airport.... Well, i think we appreciate the overcome team and the rest of you guys to test it out and gain feedback for improment.... cheerss... and Selamat Hari Raya to all muslim people ya.

did you try the tweaks here re: Battery Recalibration and Reconditioning…
http://p1000.teamovercome.net/?page_id=68
and do note that:
battery wipe by itself would not immediately “improve” your battery life. IN FACT, during the first charge cycle after a battery wipe, you might notice a slightly less than optimal battery-life! This is because, the stats have to be rebuilt, which is why after a couple of FULL charge cycles after the battery wipe, when the stats are properly “repopulated”, which is when you’ll see the difference.

yes, i have did that after going through the forum, and today is a second day after the wipe, but i would recognized that if you put the tab in Normal stanby mode, the batt will drop about 1% in about 4hrs since i have started to monitor this morning... well, i will continue to monitor aand post it again. thanks for your advise.

my one on overcome 3.3.1 seems to last at least 1 hr when the battery notification show 0!!!

I have tested my second days after batt wipe, it seem that if we put at standby mode the batt really better then earlier versions, i can notice that last night was 26% at 2.30am and this morning waikup at 7.15am, the batt indicate 24%. (Note : my wifi is on, except BT and GPS is off).
My conclusion for now is that the OC 3.1 batt life is ok and even better when it was in standby mode, however whenever any application for example browsing internet or starting reading news, the batt will start to drain off like 1% every 3min (my estimation point of view).
Hope the OC team can help to improve from here OR the nature of this OC 3.1 is normal on this circumstanses. Cheerssss....

[Q] [i9000] Team ICSSGS RC3.1 - Battery Life

Hello everyone!
I've installed few days ago the onecosmic's ROM RC3.1, beatiful, perfect, smooth bla bla.
The problem is: i'm seeing so many post of people saying that with full charge, phone can stay alive for an average of 1 day- 1 day and an half (24-36h) with a normal use.
My phone can last 13-14h staying most of the time in standby and it's the 5th cycle so should be "stabilized" now. 1st cycle was awful, 8h (didn't expect anything else), then things got better but i've reached this cap of 14h.
I've tried Fugu kernel at first but i didn't get much improvement so i switched to paul kernel and changed modem too (jvk->jvt).
Still can't reach the dreamed 24-36h, i mean, i don't care about having 2 days of battery life, i would like to use the phone without having to charge it in the middle of the day.
btw nstools installed and set Deep Idle on, which seems to works just fine for me with the paul kernel.
(can't post outside link -.-)
nstools stats:
h*tp://i44.tinypic.com/6duvzb.png
does these stats means it's working?
i'll post also CPUspy stats:
h*tp://i43.tinypic.com/35052qf.png
is it everything ok here?
On standby there's no battery drain effect now, but when i'm using it, i get 1% down every 1-2 min.
What do you guys suggest? do i need to try other kernels/modems? shoud i try to flash again?
p.s. on 2.3.5 stock i used to have 24-36h but there's no way i'm going back to GB, i love ICS.

I used to have 24h of battery life, but I don't know what happened, after a week or so now my phone is draining 20% every hour, dead by noon...
Tried NStools with undervolt, and it didn't change anything.
It's now an useless piece of junk... this is retarded, either i will try reinstalling ICS or im going back to GB.

maybe your problem is caused by an app, or more than one, which are using push notification, you sould try uninstalling some...
Tried undervolt too, i got maybe an hour more.

Update: i just flashed again with RC3,1 and paul kernel. Situation seems a little better, gonna update again after few battery cycles.

What thing is in the battery status menu?
If it is media server: settings-->apps-->all--> Mediastorage-->force stop(dont wipe data)

sure! with the new paul kernel the battery life is better! amd now i'm trying the last glitch...my phone seems to work better...!i will hope to have also a good battery life without hard drain (with didle support maybe it's possible!)

actually, there was a lot of "Android OS" usage, maybe something went wrong from the beginning, the phone wasn't going to deep sleep state when put on stan-by and use more cpu than necessary when active, that must have been the main issue.
As i said, installed RC3.1 again this morning now everything is gooood
Lots of facebook, whatsapp, camera and 1 call, still have 67%. When put on standby battery almost doens't drop at all (checked on battery graph).
I think it's solved

I've the same problem. my battery life sucks...
Now my question. Where can I find/download the paul kernel? I#ll re-flash it too .
And my second question, do the "devil - der teufel" kernel do a great job too?

dunno about devil kernel, i read that for someone is even better than paul and it solves also "green screen" issue that appear when you lock the phone. I'm happy with this config so i won't touch it until RC4
I confirm that ,now, when my phone is in stand-by, battery usage is almost 0.
btw paul's kernel can be found here:
h*tps://w*w.dropbox.com/s/ts8j2o7wuklq9zg
(sorry about the "*" in the url but it won't let me post link 'til i get 10 post -.-)
is also in the first post of the Team ICSSGS rom btw

I have flashed RC3.1 yesterday, it lasted for 8 hours. I was using it heavily to check all the features, syncing the contacts etc. I have drained the battery fully now. Will charge it upto 100% and see how long it last now with normal usage.

Battery Drain
hello everyone - I have been searching a lot abou this i9000 battery drain on ICS. I am using ICS and Devil karnel and battery lasts for around 11-12hrs. My usage is pretty normal. I dont use phone for most of the time but still it reaches to 12hrs mark. If I check battery stats then Android OS and Display (brightness is very low) are consuming most of the battery.
Please let me know if there are any ROM Tweeks or any other way to increase battery time. Or I will have to go back to GB because I hate charing battery two times a day.
Thank you.

[Q] Need help about battery slim ics 3.2 please read !

Hey guy's i m not new to xda i m following threads from quit a time noe i flashed slim ics 3.2 on my i9000. The thing is i m getting average battery life around 3-4 hour when i m using wifi + facebook or just watching movie i don't know is it normal or not on idle i get around 1 day please tell me whats wrong ? when my battery got full charge it shows 1436mv from battery spy + most of the battery use is from screen phone is 4 month old i never tried gingerbread till now please help !! battery goes down 2-3 % every minutes some time one more thing i have used battery calibration and i too tried to charge battery from 0-100% many times still facing the same problem

Did you wipe the usual things before flashing?
If the battery bothers you, try to change the rom and see if the problem keeps going.
I had the same issue with my former android phone, turned out it was the battery itself and had to change it

My usage on average depending on what I am doing.
Screen on < 4 hours (possibly slightly more).
3g, Wifi, gps < 36 hours
3g, wifi, gps off. location based service off. limited phone use 3 - 4 days which is usual for me. I generally make a few calls (say 20 - 40 minutes), several sms and some time on xda, facebook, google+ (about an hour or so).
Currently on Slim 3.4.
1 day 6 hours down to 62%.
voice calls = 59 mins 33 seconds
screen on = 58 minutes
If you have things like 3g, gps, wifi etc all on these are also going drain the battery so a days is not bad either. Also make sure you aren't logged into latitude and turn off any location based stuff. Also don't overclock.
If you are worried you can try something like betterbatterystats from market or free on xda (just search for the thread) and see if you can spot anything that might be draining the battery.

That's pretty strange.
first of all, try a new wipe and install slim ics v 3.4. One of the reason I choose this rom is because the stock kernel has a wonderful battery management. So it's quite clear that something's wrong.
Could you give us the % usage?

Here are some SS i have attached i charged till 100% keept my phone idle for 2-2.5 hr 5 minutes of facebook and browser only and battery is 82 % now. I have install slim ics from some darky rom 2.3.7 from odin than dark night ics rom and than Slim ics. Please give me the stock rom link 2.3.3 for india it will be great help and please suggest what to do i even uninstall maps and email services ..

Here you can find some stock firmwares to flash: http://forum.xda-developers.com/showthread.php?t=1102881&page=1
Also: if you didn't, wipe battery stats before flashing a rom, with full percentage of battery.
To know the source of the problem, simply flash a stock firmware and if the problem doesn't get solved it must be the battery

So i flashed stock rom i used phone for 1.5hr and battery is 70% now 10 minutes facebook drop battery level 8-9% is it normal please reply ASAP

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
