[Q] MIUI ROM doesnt go to sleep!!

Hey All,
My Milestone running MIUI 1.6.4 doesnt go to sleep when I turn the screen off. This is leading to poor dormant battery life. The battery drops by about 10 percent for every 1 hr, when the phone is not in use(ironic, cos when the device is actively used, MIUI seems to have the best battery life). I checked the built in battery usage chart, and the thread that keeps the device awake is Android System itself. Is this a known issue? and are there any solutions available?

Had same problem!
Had exactly same problem a couple of months back and posted question here but no response.
I was able to initiate deep sleep but had to do various things such as reboot time after time until successful, open up a variety of apps, use a task killer, etc., to try and resolve problem.
I was using CM 6.0 initially and even updated to the latest update of that build by wiping everything but all to no avail. I was beginning to think that it was a hardware problem when I flashed an entirely different rom - MIUI 1.2.25 and hey presto problem resolved.
I suggest that you may have to do likewise and try another rom entirely. BTW the battery life of 1.2.25 is very good indeed. I also recommend using CPU Spy found in the market and/or CPU Stats found in the Themes/Apps section of this forum to monitor deep sleep status.
Hope this helps

[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....

Team ICSSGS RC4 problems, looking for solutions

I´ve noticed a few bugs, problems in this new version of ICS. If anyone knows how to solve them I would appreciate your advice
So, here is what´s bugging me:
1. Screen sometimes go greenish for a second or two when there is a lot of apps running and when I quickly turn off and turn on the screen (it happens when the screen goes on, that moment)
2. Overclocking seems very unstable!! ..when I OC my phone (with NStools) and do some things..after a while, it freezes and reboots. On RC3.1 version I could overclock to 1.46GHz and play games and it was very stable!
(I think they changed voltage and because of that it´s unstable, but I´m not sure)
3. When system reboots (after crash), it reboots in clock work mode -.-" ..why can´t it reboot normally, into system?
4. It´s not really a problem but, does anyone know how to remove unnecessary home screens or add them back? Is it possible?
5. .apk files can´t be sent trough bluetooth .. (message: This Bluetooth device or computer cannot process files of this type. )
Other than that I would say this version is almost perfect, flash works in browser, effects in camera, USB mass storage ..works very well.
I was on Doc´s ICS teamhackungs based rom before this one (and after RC3.1 )..and I noticed that battery life was terrible even with juice saver apps running.
I hope this one is better.

Actually RC4 has been pulled because of a Wifi issue
I flashed it last night before it was pulled, I flashed over Onecosmics 2.11 no wipe, and my wifi its working normal.

It is a great rom, I hope they can fix those minor issues.
Battery life for me has been just OK on 2.11, I have to give RC4 the 3 charge cycles before any judgement.

I've just noticed that battery life was reduced constantly in last 3 days, now battery doesn't last 12 hours, but it's the first time that happens!

Yes, so did I ..just before they pulled I downloaded the rom...I was on Doc´s ICS..but I flashed with Odin JVT 2.3.5. GB ..rooted with CF-root and then in CWM flashed RC4 ..my wi-fi was having problems but when I updated WiFix manager it was ok then.
Yea, I couldn´t agree more, if they fix those issues it could be it..the final version (without any bugs). Lets hope they do it soon so we don´t have to wait too long
btw. I was thinking, could we solve these or at least some this issues by flashing another kernel??
@Giuku :I´ve noticed that too..even though I´m not OC now it still drains a lot..or my battery become weak (It´s 1year old) . But that is not without a reason..I did put her to her limits (and my phone) by playing games so much that my smartphone reached max temperature of 60°C and then cooling it in 1min to 30°C and less.

[Q] [ASK] HElp to find out what causing this battery drain

hi all..
2 weeks ago I finally bought my very first android based HH, GNOTE...currently I'm running on ICS LPF Taiwan unroot, and very love it. one of my concern on this ICS, is the battery drain so much, considering it just sit on my pocket.
i have CPU Spy and BBS Installed, and found that it just Deep Sleep 48% and 200MHz 37 %. Kernel Wakelock is "multipdp" 25% Power Manager Services 21,2% and secril_fd-interface 19.25.
could you please tell me what causing this battery drain so much..?

The best thing that you could do is do a Factory Reset, but with all the bricking problems it's highly discouraged. I don't recognise the processes, but you should make sure that you deleted all the apps you never use, since one of then could be causing the problems you have.
Sent from my Nokia 3310 4.0.3 via XDA

After upgrading to German ICS, also had problems with wakelocks (phone never sleeped)
Done this (posted on XDA somewhere) and it worked:
Turn Flight Mode ON
Turn Off the Phone
Take out the battery for 30 secs
Plug battery back
Turn on the phone
Wait until all is loaded and turn off Flight Mode.
Also, always disconnect from the charger with screen ON and unlocked.
After using this 2 metods, never had a wakelock again (multipdp etc)

thanks a lot for both of you....

thanks for your answer for my question...
regarding that did you mean that i have to stop receiving email on my Galaxy Note..?? for me that's really important since i bought my note to support my daily job...
is it the main cause..? if yes, i think i should buy another battery as a way out.

I also have encountered the same problem with my galaxy note after the stock ics update in India.
I have checked out the earlier posts on the same issue..
Some users had the problems of deep sleep and some others had other problems..bt as far i have been able to understand this problem...it is associated with those apps which we often use..for eg i had been using apex launcher for so long...and it used to suck my phones battery like hell also coz of the widgets and the other things that it use.
So what i did was a simple factory reset and a data wipe and didn't install the apex launcher again.
I let my phones battery drain completely and charged it till 100% and simply rebooted it and removed the battery too. And its working good now.
Those things which suckedy battery included android system and display...i could do any thing about display but i force stopped may process of android system and results are good.
One more reason for battery drain could be that when we go backs from the apps on stock ics on galaxy note..the apps do not get closed comletely like stock web browser which works in the background too..so might be other reason for so.
Don not install those apps which u dont use often coz they might work in background add unnecessorily suck ur bettery.
Try the battery pull off trick it really works for majority of users.
Force close those apps and processes which u feel unnecessory.
Those whose claim ics doesnt work smooth on their note they pls go the develpers option in settings and enable the force GPU rendering option then it will work smooth like anything...
One more thing which u may already know about galaxy note ics is that now it runs all the tablet apps on ur note! Thats pretty amazing coz u need not root it or do anything...for me it worked with the apps like...adobe idea, adobe photoshop touch and all other adobe apps and some other tablet apps..download these apps directly from 4shared..so cheers!!!
Those who are not happy with their battery pls try factory reset and battery pull off trick...it worked for me and it might work for u too my friend...

if you are entering deep sleep at all then you aren't being affected by the bug where you have to make sure your screen is on and unlocked before pulling it off the charger.
i suffered from this bug after updating to ics lpy, but since following the guide above (flight mode, power down etc.) i've had no issues.
let your phone completely discharge, then turn it back ona dn make sure it turns off again. then fully charge it. i found this increased the accuracy of the battery a little, when i did it it dropped from 10% to 1% in around 20 mins, then i was able to use the phone for almost half an hour on 1% so obviously my battery stats weren't quite right.
if you've done a factory reset, and you're sure the phone is entering deep sleep ok, just go through a couple of complete charge/discharge cycles and see if that improves things

Analyzing is tought on android.
Printscreens of kernel wakelock and partial are better.
Partial is mostly what exactly is keeping awake

i still got this issue regarding multipdp and secril_fd_interface....maybe it caused by unstable network or the fast dormancy stuff...
so i went to nearest samsung center and buy a spare battery... now i have no concern about this...but still keep on eye with l2_hsic...the flight mode on and restart will solve this issue..

I was having battery drain issues myself. Got tired of checking CPU Spy and BBS etc. Worried about bricking and wiping so I...
I rooted the phone.
Installed SpeedMod Kernel 3-3 via mobile odin that didnt really solve it.
I installed Abyss kernel. Wiped everything because its supposed to be a safe wipe kernel.
Then installed Criskelo rom
Then installed SpeedMod Kernel 3-3 again and everything was great with battery life.
You have to reinstall apps and setup your phone basically but its well worth it in my opinion. Now my only battery drain is me always messing with my phone.

@gayanaji - I use Criskelo's ROM and all the Samsung apps work fine. No probs here. Many of the custom ROMS are based on other Kernels that the Samsung apps do not work with. I am a bit new to this but I believe that is correct. Just make sure to use a Samsung app compatible Kernel if you decide to do it. Also another piece of advice before doing anything read a bunch to make sure you fully understand everything with regards to rooting, flashing custom ROMS etc.

[Q] Low battery life

Hi, I have problem with my battery life, I've bought new samsung s3 mini and got it with android 4.1.2 but battery life is pretty low, it can't last for 24 hours, can I do something to extend my battery life ? I text few sms messages, talk about 15 minutes, wifi is almost always on, screen brightness is set to minimum when ever I can do it, check little bit news over opera browser (maybe 15 minutes of use per day), also make few call over viber (about 10 minutes per day).
I've read that update samsung firmware via kies can help improve battery life, what should I do ?
p.s. my phone is not rooted if that is impormant, also I am neewbie
Thanks for help in advance

I'll try that tommorow, yes apps need to be installed again (my phone is 7 days ''old'' so I don't have so many apps)
p.s. did you installed all same apps and games ? I am asking this because maybe some app or game that you had previously installed was making android OS draining battery

if androidOS is draining then it is not your personal apps, its the android system, reset should solve that. disable syncing and 3g when not using.

Root it then download setcpu or free equivalent from play store. Set max CPU to 800.
Install crossbreeder tweaks.
All info is available just search.

p.s. do i loose warranty if I do root ?

Yes, betterbatterystats the best way to narrow down whats causing the drain before you decide to wipe everything.
You'll lose warranty while you are rooted, but you can always go back to stock, and no one will ever notice
Only problem is if something gets damaged so bad you cant use odin to flash. Then you might have problems
to restore it to default state before service.

I'll try it all, just need some time to experiment, I'll post my opinion and results
p.s. I disabled this:
s-voice
active aplications
bh telekom (some app from my network provider)
game hub
samsung account
sns
software update
also all the time I am on 2G, wifi is almost all the time on, brightness is set low as it can be, power saving mode is on, now I turn of vibration for calls, etc

for me, the battery drainer was the Dropbox app(maybe i didnt set it right)....anyways,it wasnt showing that it was the Dropbox draining..i mean after i installed that app my Android OS went over 50% usage while it used to be below 20% on those battery charts...
anyways after i uninstalled it,everything went back to normal,getting easily 1 day heavy usage(gaming included), or at least 2 days of medium usage( just regular calls and text and some viber over wifi)
so, from my experiance so far(have the phone over 6 months now), i recommend you to try to remember which apps you installed last and uninstall them...restart the phone and see if that works b4 you go to factory resets and all that stuff....cheers

since I installed task killer and set it to crazy mode (killing apps every 30 minutes), and disabling many apps to get notifications (list of apps is 2 post above) my battery with medium use endurance is better, it last more then 24 hours but I think that battery could last for 2 days with this kind of use. here is photo from betterbatterystats, is anything unusual ?
p.s. next testing step is to do factory reset or install some other kernel version

task managers drain more battery imo because they wake up the phone every time and kill apps in the background that will just restart again because they are set to run in the background, android automatically kills tasks that you ran earlier after an amount of time, anyway more info here

Install Juice Defender, the free version can solve your problem, increasing 60% the battery life.

the difference is visible with any type of ROM.
I'm using the last from SamMobile since the first day with my devices...

I've tried also the AMG1 Rom, but i didn't see any difference btw. this and other roms.
I've also tried to use a unrooted rom and there is also a massive battery drain.
now i've ordered a new battery. perhapes it lasts longer.
stiff

I do not have this problem, but I use a PL ROM from T-Mobile - AMB2.
