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NFI how I ended up with that outdated version!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

HOW??????????????????

[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

Doesn't really sound normal, post screens? If the rom is 100% stock then it must be the battery

[Q] Stock ROM battery drain after playing with Maclaw ROMS

After playing around with some Maclaw ROMS (cm10.2 and cm11) I went back to stock ROM. However I had big battery drains after that.
I did a complete wipe of user and cache and dalvik. I installed stock firmware with Odin. Did it over again with KIES. But still a big battery drain. Like 15% an hour. No apps installed other than the bloatware the in the firmware.
I've read somewhere about someone else who had the same issue, but I cannot find it anymore.
Anyone an idea?

Maybe you should try to format all partitions in recovery (except your internal and external SD card of course) and reflash the stock firmware.
By the way, 15% an hour is quite normaal for me.

Custom Roms battery drain, can be the 1ghz bug .
when you did alot off playing ( such as flashing from rom to rom an formatting again in a few hours. it cost you battery .
And now back on stock rom. Try to load your battery again to 100 % and see what will happen after it .
Stock rom = 100 % - 0% battery --> +- 20 hours
Custom roms= can do it longer.
but if you are a heavy caller, gamer. the battery will be down faster .

I've had the same problem. I updated the working 10.1 october version to the december version. After switching back to october version the failure was still there. Only way to solve it was a new battery - but it costs only about 10 € ...

i think that it is true that rom by itself is still buggy with cpu governer bug that causes to be stuck on 1ghz without dropping to 200mhz on the other side...when i try another version i shall make my jugdement more clearly

i got this problem on 02.13 release when i update to 02.16 problem was solved. didnt update 02.18 yet

Perhaps you should also consider the lifetime and usage of your battery. After months of charging and discharging once or twice a day, it´s not so unnormal that a battery goes weak...which has imho directly nothing to do with the used software...

Thanks for the reply.
I charged again to 100 % en let it go to 0%. It took about 9 hours, AIRPLANE MODE!!!
Checked CPU with CPU spy: it goes to deep sleep.
No apps installed except the bloatware the Samsung firmware comes with (and CPU spy).
Maybe it's just my battery gone bad/dead at the same time I tested the Maclaw roms. I already ordered a new one (2450 mAh!), but it takes about a month to get here (if it arrives all together; I live on a tiny little island).
However... I also noticed I do not have network coverage some times. Just no network. Could it be that if you flash it with Odin/Kies not everything is wiped and reinstalled? Like modem drivers (although it's strange the drain also occurs in airplane mode). To make it more complicated: I just moved to another place, so maybe the coverage is worse around here.
I just hate it if I can't pinpoint the problem

Hi,
I think you are on 1ghz bug if you have custom rom.
When you are on stock. This is not normale, your battery is going bad
Where did you bought a new one, im looking for a new one also.

Tried the 02.16 cm11 release => no change. Think my battery is just gone. I'll wait for the new one to arrive and will see then.

Think you're right. Bah, so it ain't something that can be fixed by/in a flash.

Hi!, I'm having the same issue here:
-Super-battery drain, specially when restarting the phone, huge 20% drops.
-Phone looses signal inexplicably,5 bars and suddenly dead, restarting solves the problem, but when signal drops, the battery starts getting HOT, even on IDLE.
-Im using Carbon 4.4.2 KitKat ROM on S3Mini I8190L.
Battery was working quite well with Cyano 11 about 3 months ago, switched to MIUI ROM because a friend recommended it, ROM started to be unstable, laggy and battery life wasn't great, had the same "signal lost" issues. Then downloaded the Carbon ROM and everything went worse.
-I always do full wipe, (davlik, data, interal storage, everything).
Any ideas?

connected to Bluetooth device battery drain?

Hey I just wanted to know if this is supposed to be normal behavior. I stay connected to my pixel buds 2 all 9 hours on my work days and I don't listen to anything except to and from work which is about 50 minutes then the other 8 hours and 10 minutes I'm actually working but I don't listen to nothing I just keep one bud in my ear to reply to texts and check NBA scores and some random Google searches here and there. So I would start the day of course with full battery then by the end of my 8 hours shift I'm down to between 20-30%. Now I just wanted to know if that's normal?

Well that's a way too much battery drain. Have you checked at the battery settings what's causing it?

Yes I've done clean Flash of latest stock firmware and I've been using latest kiri kernel. I've been obsessing with better battery stats and I've only seen one culprit which was Google Play services but a clean Flash fixed that. It's like standby time on this phone for me is non existent. However I will run complete stock without root and will investigate further.

Question Funtouch OS 13 upgrade issues

Hi all, I have just updated my Vivo X70 pro + to Funtouch OS 13 from the Trial version option from the system update options. Once the update was done, the first thing I noticed was the temperature of the phone which shot up and all the things were stuttering to run smoothly for around half an hr straight which made me want to downgrade the OS again. But now it is running smoothly.
But I would love to know a way to downgrade it.
Also, the battery on this phone is just disappointing just after a year. It gives me around 4-5 hrs of SOT and I end up charging the phone for 2-3 times a day. Please let me know if anyone else is facing the same issue and if anyone has found any fix for the issue.

I have done the uppgrade to and i have non problem , all it just good and the best is that VoLTE is included i bought mine in april , the battery is just fine , it holds like 2 days

Damn... Mine drains even when the screen is locked. It's 33% less in the morning after i sleep. Is this normal?

Can more people give me some reviews for the battery?

Also, just got an OTA update and my phone seems to be working perfect again

how did you downgrade?
