I rooted my Mini 2 days ago using the Universal root (Xploid) and my battery now lasts only 21hours on STANDBY with no calls, sms, data, gps, or wifi, and 9 out of those 21 hours was in Airplane mode as I was asleep!
Anyone else had this and found a solution?
Here is a screen shot of my battery usage..

I would normally get at least 2 days of normal usage, and probably 4 if I didnt use it hardly at all.

Have you turned your phone off since you rooted?
I noticed on mine that one of the tools used during the rooting process continued running on the phone afterwards and was using most of the CPU time, thus draining the battery (but it doesn't show up in the "Why is my battery dead" screen, as it's a linux process rather than an Android app)
Try turning it off and on again!
I have restarted but not actually powered down und up again, I would of thought this would be the same, but i'll try it!
Thanks!
Same situation for me. I rooted X10 mini Pro and battery works only one day without any calls and few SMS. I turn off the phone, try to change battery but still is battery life so bad.
But in my opinion battery is drain normal to the from 100% to 50% and that s least 18 Hours. From 50% to 1% least 3 Hours...
Again, I come from the hero so do not know what options you get on your recovery image...
But in there, if you do have this, let you battery get to around 5%, and wipe the battery stats, reboot, charge until full, turn off, charge until full, turn on, charge until full. This should help give you a nice full cycle. Worked for me anyways.
I had the same issues on my hero when I rooted, and have been browsing teh x10 forums as I am thinking about getting one for my fianceé.
I noticed the battery life after rooting is very bad also. Much worse the the MyTouch Slide. I'm was running ADWLauncher beacsue I don't care for the Stock Sony one. trying out Helix now to see if it is any better. This sucks because before I bought the phone I read about how good the battery is. Can rooting really make the battery drain faster?

no recovery image on X10 mini
no wipe battery stats option because of that
but thanks for your help anyway
Same as mine, after rooted, my phone drains battery too much, 3% in 1 hour.
I figured out that you should reboot your phone to bring it back to normal. I have reboot my phone and now it drains less battery, just 3% in 8 hour when the phone stand by.
Give it a try guys.

What do you mean, reboot? I've rebooted many times, I've even tried different batteries and still the same problem. Do you mean un-root? If so, how do you do that?
Mine seems to be ok after turning off and on again.
How did you try different batteries?? Or are you a Pro?
what do u have running in the background?
I noticed the diagnostic process runs constantly and takes up much of the CPU power after I rooted my X10 mini, and that seems to be the major cause for draining the battery.
I wonder if anybody else here has the same experience?
Hey try using Juice Defender .. it works like charm for me !!
Bravo Juice !!
Never thought that rooting will drain the battery!
going back to stock rom? (never)

I do not understand the problems of Android battery truth is that they are problematic.
I configured to use the savings SetCPU
Set cpu is not the sollution.....x10 mini has a weak cpu(its not verry weak but its not good)and if put its 600mhz down to 400 it starts lagging and down 400 it has parkinson.................follow my instructions( in my previous reply) and u will have better batery plz i want everybody solve their battery problem.......
The fix suggested by devilakos is (imho) needed on stock rom also when recovery is installed. I applied it to both my stock roms (see sig) and has a positive effect on battery life.
The problem is in the chargemon/charger configuration, independent of build.

I assume you are playing a lot wiht your new phone which drains battery because of the display. You should start tweaking display settings as xperia phones usually dont have auto brightness (dont know about Ray thou). Also get rid of that task killer but instead get memory tweaker or V6 super charger if you have root permissions. Try changing from 3g to 2g. As 3G coverage is not that good in India, you ll end up draining more battery even when idle.
Spare parts has auto brightness apk should work but I get 3 days out the neo so you should atleast get 24 hours

Moving this to General-Q&A section as I don't see any development here. It looks its related to other device model even.
I will move some others and try to keep development section only for development.
I think it will be good for everybody. Any help is always appreciated.

I'm having an issue where phone idle is taking up about 50% of the battery drain on my phone. I left it on overnight on flight mode, and half of the battery vanished over the course of about 7 hours.
Anybody know any fixes, or related issues?

and in general everytime i recharge my phone, >50% of usage is to CONTACTS !!!
the phone drains on standby as if i was playing a game !!!!!!!
Hi guys - I'm sorry I dont have a solution but I will add something that I've recently experience with my Xperia Neo.
I move around alot within my job - travelling constantly around the city between 5-100km every hour or so and I noticed that during this time my phone's battery was below what I expected - it would last 12 hours and it would NEED to be put on charge.
I asked a friend of mine what he thought and he suggested turning off the 3G setting and selecting 2G only. This is the fix we tried and it appears to have worked.....but...
if only it was that easy - my phone appears to have come from China and so I actually didnt have a menu option to select 3G - the only option was 3G and nothing else, so I had to flash the phone with international firmware to get the menu option.

Hi, i find this very weird, my T-Mobile G2 Touch (HTC Hero) lasts easily 2 days with 1 charge. I'm now using a ICS 4.0.1 rom made by '
Glassmacka'' and i'm verry happy with it. Before this I tried several Gingerbread roms and the Cronosproject rom was the fastest and most stable one for me and my phone lasted 2 and a half day with that rom. So I advice you to try those roms.
Cheers.
I'm using decked too n i get 2-3days battery sometimes,wat i realised is battery,drains faster when mobile network is on,so i leave it off most of the time....

Have you tried reducing the max CPU speed in perf. settings? Higher CPU speeds increase performance at a cost of lower battery life
I've tried several gingerbread roms (Decked X, Cronos, Elelinux-7.1, Ligux) and they all drain the battery in less than 1 day. It's not terrible when my phone is just sitting there (e.g. overnight) but when I start using it the battery gets drained by about 1% each minute or two. When I look at what is using up the battery, Display is always the biggest user by far. I have brightness set to the lowest setting.
I tried a few different kernels, LV 0.5 and 1.0 and FlyKernel 13. I have the latest radio installed, 63.18.55.06SU_6.35.17.03.
I have tried different min/max CPU frequencies but they haven't affected the battery life substantially.
Right now I'm using the Elelinux-7.1 rom with ONDEMAND governor (245/576MHz), JIT enabled, surface dithering disabled, 16bit transparency disabled, and Compcache RAM disabled.
Your help is appreciated

yeah what your saying spot on. i generally get about a day and a few hours with the decked rom. but yes there is a horrible battery drain when the screen is on. i also find that sometimes the battery will go down as much as 2% per min or two which i'm sure can't be normal
however, in standby mode the battery hardly depletes, with the decked rom i find that when in standby the battery will only deplete by maybe 1% or 2% overnight. on a few occasions i've woken up in the morning to find the battery at exactly the same percentage i left it when going to sleep
I installed EleLinux 7.1 with the last Radio, used Swapper2 and partition with Swap my Sd Card.
The battery now is 48h before charging, with normal use and 3G always connected.

Wow, nice battery life you got there... 3G always on?... I need to tinker my hero again, I guess
Finally I didn't install LasVenturas Kernel. Looks like it will realy improve my battery life, but I read about it and it saids that USB is in beta and could fail several times.
Anyway, Data mobile connected 24/7 and 48h.
Just amazed about EleLinux nice work!!

Decked here (though, HabaDecked version) and my phone has: 1d, 20h, 16 mins and still 57% battery remaining. My display was using the most battery (40%) followed by Cell standby with 22%.
On topic:
You don't need to flash roms like crazy or change them because your battery life is poor. The rom entity doesn't have direct effect on the battery as the kernel has.
Leave your current rom (or install any rom you want - wipe everything), give your phone time to 'swallow' the new rom and 'settle' with it. Basically you did said that the battery is new and the battery isn't fully calibrated (which will settle down in 2 or 3 days), therefore the battery stats displays erroneous data!
Hey, my phone has been bought in on September 2011.
I noticed battery keeps my phone shorter than it's been before.
Is it either by ICS or battery is just getting old and less reliable?
I use XWLPG and my hourly battery usage is about 0.8% to 1.4% (battery monitor).
Sometimes after I unplug from charger and keep phone alone, battery usage is about 0.1%... dunno why and how....
I use only few background apps:
- network type marker (to show I am in either 3G or 2G)
- TotallRecall for call recording
I know in GB I could unplug phone for night and by few hours I could loss max 1-2 percent (sometimes even 0% by 6 hours).
Now I lose usually 5-7%.
Do you have similar symptoms in your phones?

hey pal i also bought my s2 during the same period and my batt is good enough even now
u have to check which apps is causing the batt drain for u since in ICS, also turn off ur data connection when not in use since they also cause heavy batt drain
u can try Better battery app from store to see the wakelocks that is causing batt drain
ps- before all change ur modem and see
There are a couple of reasons why your battery is performing like that.
Some of my friends have reported lesser battery life when they switched to ICS, even when running the exact same apps. So you might want to try different ICS firmwares/roms to see if that will make a difference. Although, I'm using XWLPG also and it drops ~7% overnight. Same as your's.
Also, if you find that your battery levels are wack, then you might have a faulty battery. On my GNote, I sometimes have to push the battery upwards while turning the phone on so that the contacts touch. I think that it may have been due to constant charging (may be wrong) So, yes, there is a possibility that your battery is getting 'old'.

Hmm I am glad to hear you've got similar power drain during night. Perhaps ICS is really more powerhungry than GB. I will test in Better battery app for wakelocks occurence.
I don't know how and in what way the battery monitor reliable can be, especially when I see hourly battery drain. Generally sometimes I see power drain at 0.1-0.2%, sometimes at 1% but in same time CPU was doing nothing... (deep sleep).
I found Camera eats a lot of power compared to GB... or it is only my imagination

Dear 10.1 forum,
i come to you from your little brother the Galaxy Tab 8.9.
Now i know this forum is for the 10.1 only but sadly we hardly have any devs for our device and we have run into quite a serious problem, so please hear me out.
One of our last devs made a port from the P7500XXLQ8_P7500OXALQ8 and P7510XABLPL_P7510UELPL ICS release.
Flashed fine and all was good but now we have really erratic battery behaviour!
The tab, better put the android OS, keeps thinking the battery is discharged, when however it still has loads of battery left. CWM can be booted and run for 5 hours or more.
So some of us let the battery run out completely (in cwm) then charged it fully and wiped stats. booted again and some now don't have any more issues. some still have some.
here is a pic from my discharge and you will quickly see that something is f*cked:

}
1. The tab starts out alright with normal drain while surfing, watching news etc
2. i turned the screen off for a while and had a massive drop in only a few minutes
3. turned it on again and the discharge seemed normal
4. switch to flightmode for the night (i always do that) and turned off the screen.
5. the next morning i woke up to a switched off tab. i turned it on and the android OS told me the battery was empty. i shut it down.
6. i then hooked it up to the charger (for only a minute) and proceeded to boot. the system then once again read the correct battery stats at about 60% just about where it was last night before i turned the screen off.
can anybody maybe shed any light on this issue?
this is affecting quite a lot of us in the 8.9 forum and is a pretty big issue as you can see.
some people even report of this problem carrying over to another ROM! which just completely baffels me...
please help your little brothers out
thanks a lot

There is a very old thread, probably like 8 months old in the General section of this Forum. It its titled something like "for those with battery calibration issues" use the search feature. Out tabs had this issue with some roms (some still do) I used the method posted in that thread to solve the issue. My post is still there I'm sure so you could search my user name too. Good luck. Let me know how it goes.
Have seen some suggestions to use the battery calibration app. Is that the probable solution? Can u pls elaborate as many are affected with this rogue issue now.

This method of calibration worked for me a while back when my tab was displaying this exact same erratic battery reading. The op gives a thorough explanation but it amounts to:
1. Charge tab to 100%
2. Power down for 1 hour
3. Power on (my tab was at 96%)
4. Drain to 46%
5. Power of for 5 hours or over night.
Your tab should start reading the battery accurately after this. Good luck! If it works repost to your fellows in the 8.2 forum.
Sent from my GT-P7510 using xda app-developers app
thanks for that link. Looks like an interesting thread !
PS: based only on reading that thread (no experimentation yet) it seems like the OP changed the procedure a little along the line... He added the new procedure to post #1, but it's also in other posts, e.g. #41 and #161.
QUOTING vlad_z (minor edit for clarity)
here is calibration procedure which was modified down this thread ...
1. in normal Android or CWM/recovery let it sit till battery in terminal will show less then 3700. The less you can get it the better. 3400 is probably absolute minimum.
Code:
The most sure way to check this is in terminal, execute this command:
cat /sys/class/power_supply/battery/voltage_now
or through adb:
adb shell cat /sys/class/power_supply/battery/voltage_now
your good discharged start point should be anything below 3700 (3.7V).
If your tab is telling that you have 0% capacity but voltage is more then
3700 then keep rebooting tab (this will refresh counter for a moment) or
just boot in CWM and let tab run/sit there for some time.
2. shut down tab and let it sit for 1 hour at least
3. plug it to charger and charge it for 5 hours.
(PS: does not matter whether tab is on or off in this phase)
4. disconnected charger and let it sit for 1 hour. (turned off)
5. boot up your tab and test it, it your battery still not calibrated you can flash back your backup and repeat calibration procedure.
drat...
why did I do what I did :-/
so, I was on P7510 port for P7310/P7300, and no battery issues.
I decided to do the battery calibration method described by vlad_z (the 2nd method, with 1 hour power-off at dead and at full battery).
Since then, my battery reading in Android is
- dropping rapidly (about 25% per hour of use)
- jumping higher after a system restart...
so I actually uncalibrated it using this method
I think I'll try vlad_z 1st method now, hope for the best.

This method of calibration worked for me a while back when my tab was displaying this exact same erratic battery reading. The op gives a thorough explanation but it amounts to:
1. Charge tab to 100%
2. Power down for 1 hour
3. Power on (my tab was at 96%)
4. Drain to 46%
5. Power of for 5 hours or over night.
Your tab should start reading the battery accurately after this. Good luck! If it works repost to your fellows in the 8.2 forum.

Anyone have any ideas what to look for? I dont think I have a battery drain because with the screen off I lose about .5-1% every hour or so. But when im using the phone, the battery seems to drain very fast. The most screen time I have gotten is 2hrs, and its usually less than that.
Brightness does not seem to matter, I always have auto off and have tried brightness at 20%, 30%, 50% and 60%.
Use this application to locate Battery Drain https://play.google.com/store/apps/...mNvbS5XYXphQmUuYW5kcm9pZC5CYXR0ZXJ5RHJhaW4iXQ..
Update to the latest firmware or put a custom ROM.
The problem has been resolved. I had also a fast drain battery.
I even had the screen On during the night.
When I closed the eyes it was Off, but in the morning at my wake up it was On
Thanks I'll try the battery drain app.

The battery of my SG3 drains so fast I'm evne thinking of returning it (bought it yesterday). It can't be normal, it's almost like my old iPhone 3G. It goes like 1% per minute or so while browsing.
Did this fix and disabled WiFi, no luck.
Gonna try that app and see if it helps.
I think mine is like that as well. Maybe 1% minute when using heavily. Also thinking selling it. Can't return, bought on Craig list.
Very strange behavior. Something must be wrong with your soft or hardware because this is smartphone with the best battery (except razr maxx).

I loose 1-2% per hour with sync + WiFi or mobile data. And only 1%/4h when screen is off in deep idle and power saving mode.

I am experiencing the same thing since i flashed omega rom v13. i was getting 5/5.5 hours of screen time on stock Samsung rom before i flashed. Right now the battery drains 1% every 2mins when the screen is on :/ (brightness has alwsys been around 20/30%)
Only thing that has changed since i flashed is the fact that i had wifi off during sleep on stock but now its always on. I have tried setting it to always off but it automatically switches to always on everytime i do it for some reason.

I believe this is normal with new devices. It takes time before Li-Ion batteries "adjust".
Flashed my phone to another rom, JB 4.1.1 and it's the same. So no, it's not software issue. Hardware? I don't think so... the phone is new and works just fine. The problem is the battery that it's new, or maybe is damaged... who knows (probably not).
I have the same problem. I see people post threads the battery, that lasts 2 days !
I'm thinking of buying a new battery, just to check if it is a battery thing, if the battery is ****ed up or something... The Galaxy S3, should last for atleast one day! and I can't get even that! is there a fix for that? I can post my battery use from the settings if necessary.
There are loads of threads about battery drain, a lot of it relates to Samsung bloatware and background services like face awake etc, you just need to explore your phone, learn how to use it, and see it up properly.....it is not an iPhone...it requires independent thinking skills
I'm experiencing the same problem on CM9.1. Try draining the battery fully twice. That'll calibrate it and improve battery life.

That's pretty much what everyone is saying. I've never drained it, so I'm wating. Hopefully it'll work.
It can't be software because I changed ROMs like 5 times, everytime installing a different one.

Since two days, I'have the same problem.
Before Wednesday, I'haven't issue about battery drain. My phone battery worked more than 2 days idle with about 4hours screen ON and 1 hour voice calls.
But now, it works fine between 100% and 60% and then, battery drain starts. Just a few hours for the phone to indicate that it's remain 5% of power.
Do you think they are a background daemon running sometimes (why since two days?) ? Or it's a network problem ?
I'll try to wipe my battery stats and fully charge the battery.
Currently, my SGS3 International works with the latest UK firmware : PDA/XXBLG8 - MODEM/XXBLH1

It's not normal. My SGSIII drops 1% every 8-12 minutes while browsing...
