Hey I installed MIUI-NB a few days ago when it was released and am wondering how the battery is or if its supposed to even out? Mine lasts about 5 hours on light use and just an hour ago I had it at 87% and its now at 15% and all I did was mess with the theme a bit. I even have the data off. Is that normal for MIUI?
tough call, i flashed back to stock, had serious problems, i liked the build but too many scripts ,my phone couldnt hang, great idea just too muchfooofooo
you think the scripts have to do with the battery drain? I heard extended settings also causes battery drain.
1) Have you done atleast 3 battery calibrations?
2) If you have, does the battery stay bad even on froyo stock roms?
3) if they do, then your battery is most likely faulty.
Yup done the calibration and I can get through the whole day on a 2.2 rom so its not the battery.
I'm using MIUI-NB with Glitch v12. With JuiceDefender running, I can get more than 48hrs on light use (texting, car music, light gaming), and going 24hrs with heavy use is no problem.
Like the creator said, let it settle.
yeah for sure, what were you getting the first 2 days?
Problem with Titanium backup
Hi,
I just flashed the MIUI-NB rom. Looks really great.... but I previously had a different rom and had taken a backup of my contacts with Titanium backup. But now when I try to restore the contacts with titanium backup I see that its successful but there are no contacts. And when I choose to restore App+Data it gives me an error stating the contacts app cannot be installed.
Please can anyone help me out here.
Thanks a lot guys.
GPS
I flushed this rom several times...could not get GPS working.
I've followed the instructions: flush, wait, reboot, wait, foxGPS, reboot, angryGPS lock test.
so when I do angryGPS lock test, it looks like crazzzy but after that GPS would stop working at all!!! no mater what I do! I have replaced lib files for FFC so maby that what cosing it.
By the way what is the best stable GB rom for the vibrant for daily use?
I've been using boinx V and 1.3.1, but now I'me tiring to move to 2.3. I've also installed FFC just a week ago.
Please help!

I was trying to calibrate my battery and I believe that I messed up (meter is even more inaccurate now) Does anyone know of any GUARANTEED methods for calibration? One that works without charging the phone while off? (Jt's new CM7 build wants to keep turning on rather than staying off and charging.) Does anyone have a stock batterystats.bin? (Just in case)
On another note, I cant make backups through CWM (It stops after trying to backup boot image. It simply states that there is an error (bad boot image or something))
It was my understanding that the batt calibration needs to be run through a few cycles to figure out how much battery life has been depleted..ex..after resetting my b statts via cwm started with a full batt charged over night, my batt about 6 hours later said I was below 15% but lasted another 8-10 hours before it actually died...with each progressing day my "percentage" got more and more accurate as the memory figures out where completely dead is and adjust the percentage accordingly...end result aftera few cycles full to empty I have pretty accurate bstatts....charge it fully..reset your stats and wait a few days trying to run the bat down as far as you can...i let mine go till it died...and you should be good or at least know if you have a different issue
As for the nand backup problems which recovery do you have? I used both times_infinity and otb's newest 3.x.x.x. And have not had problems with either??
Edit: I had never toyed around with cm7 before and after doing so I realized that cm7 reparations your system to a different format I dont believe any of your nandroid backups you did that were pryor to cm7 will properly restore once you do the switch, you can only restore nandroids made with that particular cwr for cm7...i believe its the orange one...and even so I haven't messed around with it enough to know for sure but hopefully someone who knows more than me will chime in and get your backups working correctly...how's your batt life doing?

Ok. I just tested backing up after flashing otb. Seems to work now.
I am working on the battery calibration now.
EDIT: I was on CM7 and OTB for CM7 with a different CWM v3xxxxx (I liked the purple colored version ) the whole time. It could have just been an issue that created itself. . . seems fine now after just sticking to the OTB's bundled version of CWM. It sucks. I liked the purple.
Still working on the battery.
I've been using bstats.zip to periodically calibrate my battery after flashing...
Recently, I've been getting an error message about scripting and changes to Android since 1.x...
Is there a newer version of the battery stats zip around?
Okay I need a ROM with battery for tonight only! Going on a night out, getting wrecked and all that, and the last time I did it, my phone died and I really needed it later in the night to contact my mates when I was a mess. I don't want it to happen again tonight, even if I turn data off and everything.
So what can people recommend? Is Oxygen a good shout??

Stock rom/

You do some really heavy usage there if you can discharge it that fast. Mine lasts 24 hours easily with medium usage. I've only tried stock, villain and CM7, and from my experience CM7 saved the most battery (in idle mode at least).
Well, I can't comment on my usage as I was disgustingly drunk that time. But I really don't think I had data on, and the only thing I was doing was texting. A few calls here and there.
But I have a stock nandroid I may go back to, or I might just go for it with my MIUI. It may have been the version I was on?
Stock...i feel...tried villain2.4.2 also, but back to stock now.

The actual ROM wouldn't play a massive part in battery life although of course it needs to be included, what you need to do first and foremost (assuming your rooted) is get Titanium Backup (PRO version) and freeze all Samsung bloatware, there is a spreadsheet on page 13 http://forum.xda-developers.com/showthread.php?t=1069924 freeze everything you don't need, personally i froze just about everything i could including Maps, anything you need to use occasionally just defrost it, use it and freeze it again, don't use any battery saving apps like Juice Defender or the likes as they use up as much battery as they save, install better battery stats and check what wakelocks are keeping your phone from sleeping, obviously things like bluetooth,GPS and the likes will drain your battery so keep them off while not using, sign out of any apps if your not using them,i can also recommend Cognition ROM ive been using it now for ages and it's always good on the battery, and last but not least search the forum there have been hundreds of battery posts on here over the last few months.
After all that you might get battery life like i do (see screenshots)
Insanity
Go for the insanity ROM, only problem is, whatever ROM you choose, you will have to calibrate your battery.
stock ...
A couple of months ago I installed the AOKP ICS rom Then JB and found it about as good as you could want, but this is not about how good the rom is. I have been flashing a couple of years and know enough to get by. As much as I loved the rom i was almost ready to flash back to stock because I was unable to get any battery life. I would always use at least 8% at night and up to 15% during the day. I just couldn't understand how so many people were saying they were getting great battery life. I went through all the posts and tried every option i could find, watching wakelocks every time I picked up the phone, changing my router settings, turning off everything on the phone that made it a great phone. When I originally installed ICS I did a total factory reset, cleared all cashes. Spent hours reading everything I could find about battery life problems. When i flashed JB it was the same thing. I have been flashing the updates every week. Clearing everything every time.
Last night i was about done and figured I would try this one more time. I downloaded the rom and Gapps again, but this time i did a factory reset 3 times and cleared the cashes 3 times. Then when the system was installed I downloaded clean apps from the the Play store. I installed everything normal, all sync settings on, the phone is set up just like you would want it with full functional apps. This morning I woke up and checked the battery and it was down 2% for 5hrs! That is the best I have ever seen and I think about all you could ask for. The history had no wake locks, No awake times when the phone was sleeping. Now at 10 hrs and and 5 hrs of lite use I am at 82% and still no wake locks or anything unexpected by any apps like I always had before. Google Now is running, sync is on, like I said the phone is set up normal not everything shut off.
I am not saying that you need to clear everything 3 , 4 or 10 times when you flash a rom or not use TI to restore your Apps. What I am saying is, if after flashing a rom you are not getting good battery life or you are having any strange lock ups with your phone THEN start from scratch and make sure every app on your phone is perfect. BTW my phone was getting terrible battery life but working as smooth as butter all the time. I didint have to wait 3 battery cycles to get get 10 hrs out of my phone, it worked as I said from the start. If you phone isn't doing as good as other people are and your not expecting to get 2 days with 10 hrs of screen time, Clean out everything and start over, esp on a Rom like AOKP, these phones should work GREAT and it only takes one bad app to kill things.
So listen to the developers and clean house if things aren't right !!!!!!! It takes more time at first but over the last 2 months I have spent about 10 times more trying to fix the phone.
Do some of you other users get 8+ hours of screen on time? I got my i777 around launch time and I don't think I have seen over 4hrs of screen on time. I have tried a lot of different ROMs, like aokp, shoshock2, and currently cm10, and my general consensus is 3+ hours is good.

Never seen 8 hours with stock battery. Max I have gotten is 5 and a half. I could probably get more on Shostock but I was on AOKP JB
I'm going to have to do this tonight. I'm really not looking forward to it though because I've been trying to unlock things in Fruit Ninja but I want to get this thing working right so that's how it goes.

Just back up data
im going to try this, i was using the wipe 3 or 4 times method when i had a sony x10 phone a year ago and it seemed to make a difference.
aokp is a really great rom and on the previous version my phone could last a full 24 hours (about 9 of those hours probbaly not really any use)
latest version the battery is a bit trippy for me so im going to try this and i wont be surprised if this is all true.
thanks!
Just an update. 16 hrs, 1 hr screen 69% battery left.
To SteveO I would not restore any apps you have with a backup. If you do the complete wipe it seems that the Play store actually downloaded all the Apps fresh on its own. I think that may have something to do with really getting a clean plate. I have wiped many times and only one other time did the Play store auto load my apps.
I also recommend wiping internal and external storage everynow and then. Backup pics, music and the such

I had a feeling that's what you meant, to NOT restore a back up.
As for the "auto load" from the Play store, are you referring to when it asks you on start up if I want to restore my apps from Google Play you're suggesting I say yes, correct? Is that what you did?
I was planning on making a list of what's on my phone now and manually downloading each one and installing.

So what's the point here?
In order to get great (or better in this case) battery life of AOKP, do
1. wipe 3 times
2. install and run one of the clean app from Google Play. Which app, actually?
For some reason, I "feel" that after performing TB backups (user data backups), the battery life gets worse.
There really isnt any "point". I was just letting others know what i did to GREATLY increase my battery life. I dont think it has anything to dowith this ROM. I think if you flash any Rom and your not happy with the Battery life it may be a bad apk that doesnt get cleaned out with the normal route.
I advise installing ALL your apps clean, not any one.
I mentioned that the PLAY store automatically offered to reinstall all my apps after this clean wipe. Other times i have flashed it didnt do this so it makes me think that for some reason something doesnt really get cleared as we think it should, again no expert, only telling what i found after about 20 Rom flashes over the last couple of years.

I just had a really good test of this procedure. My usb port crapped out so I returned my phone for a warranty replacement.
My old handset has been laggy since upgrading to Jelly Bean. I'd always restore apps through Tibu, only restored data on a few apps.
Fresh clean I777 stock Sammy, runs smooth on ICS.
Newly rooted, AOKP 11/9, basic GAPPS and the same Tibu restore => laggy.
So I factory reset, wiped everything including internal storage, let Play restore my apps, input all the app data manually, and this phone is smooth.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

Hello everybody,
about two months ago, I had an issue with my installed ROM on my Redmi Note 2 Prime (I think it was this one: http://forum.xda-developers.com/redmi-note-2/orig-development/rom-cyanogenmod-12-1-t3288916 ). I decided to try out another ROM so I installled Bule's Mokee ROM ( http://forum.xda-developers.com/red...nt/rom-cm-12-1-mokee-bule-mokee-blue-t3328382 ). After a few days with this ROM I recognized a big battery drain while screen off so I installed BetterBatteryStats to get some more informations. It told me that about 50-75% of the time my CPU was running at 800mhz instead of deepsleep (at a normal day with about 1-2h of Screen-On-Time). It didn't look to me like something is creating a wakelock though (but maybe I am just unable to see this). I tried the next ROM: Daniel Pinto's CM12.1 (http://forum.xda-developers.com/redmi-note-2/development/rom-unofficial-t3310551) and again the same issue! I tried a full wipe of my internal storage, did not install xposed and did not install any titanium backup. The battery drain didn't go away. So i flashed another ROM: SlimMIUI V7.1.3.0 ( http://forum.xda-developers.com/redmi-note-2/development/rom-slimmiui-dev-stable-t3296594 ) and suddenly there was no more screen off battery drain! This went well for about three weeks and now I am facing the old problem again! Please tell me what I am doing wrong since I don't believe it's a ROM-related issue.

What I have tried so far:
- changing ROM (clean flash)
- not installing xposed
- not using old backups
- changing the battery
- using airplane mode
Also, I wonder why there are these gaps in the battery history since I didn't reboot yesterday...but these gaps don't appear every day.
Please help me to fix this really annoying problem and make my RN2 great again!
Thanks,
Kooneybert
The biggest drain comes from all the Xiaomi bloat. Read this thread for details on how to reduce the bloat. In my experience, the second main culprit is WhatsApp. I've had to stop it from giving sound notifications (or even vibrating) when messages come in. Now, I have between 90%-95% deep sleep on idle. Basically, anything that turns on audio could be a problem, because sometimes audio doesn't go off afterwards.
You might want to try GSAM Battery Monitor for more information about what is eating up your battery.

Thx for your reply! The problem is not MIUI-exclusive. CM 12.1 from Daniel Pinto is pretty slim but gave the same result (from the first day on).
Whatsapp can't be the only problem since all my friends use it and nobody have this problem (some of them also even have a RN2). Also, my phone is in silent mode almost all the time so no app is allowed to make noise or vibrate.
I just installed GSAM Battery Monitor but I don't know how to use the app/read the provided data. I could use some help there, too.

You can only be sure if you have a really skinny ROM whereby all the unnecessary Xiaomi stuff has been removed. There are all sorts of things going on in the background - including things embedded in the boot image.
There are also possibly optimisation issues with the kernel. All the ROMs seem to depend on the same binary kernels, since there is no GPL release of the kernel source code. You might want to try one of the skinny boot images by @jajk
As for GSAM, the best to learn is by trial and error (tip: tap on everything visible to see where it leads to, and what information it gives you).

...on all three ROMs? Only for me? With this effect? On some days, it reduces my battery by 50-80%! Hard to believe it is not a bug. Also, SlimMIUI has reduced Xiaomi-Stuff, Daniel Pinto's CM 12.1 looked even more clean to me.

Aren't there different kernels out there for the RN2? Bule's Mokee-ROM uses a modified kernel e.g. Does every ROM come with a certain kernel or may it be applied from the ROM before? So maybe I am still using the kernel from Bule's Rom with my MIUI?

This will help me to read the information but it won't help to understand them, too. What do you think about this:
Kernels: You can't compile a custom kernel without the Xiaomi kernel source code. All you are left with is tinkering with ramdisk in the boot image

...is this normal? The Kernel is the biggest battery sucker on my tablet aswell (which still has great battery). What do you think about the 8,5h of wakelock time produced by the kernel? If this is the problem, what can I do to solve it?

A "screen awake" of approximately 50% seems to me to be highly excessive (at least, if the phone was mostly idle). In nearly 12 hours, I have a screen awake of 55 minutes - so 8 hours in 15 hours seems strange. How exactly were you using your phone during this 15 hour period?
Perhaps the custom boot images by @jajk might help (see the first link in http://forum.xda-developers.com/redmi-note-2/general/roll-skinny-miui-t3309873). I am currently on v714-15 of the custom boot image.
Sounds like you may be having issues similar to what I was dealing with not too long ago, but my 'solution' was to install Bule's Mokee (still don't know why this ROM worked where so many others failed). Daniel's CM 12.1 and Xiaomi.eu were both giving me significant drain with and without the screen on to the point where I was sometimes finishing the day with an hour and a half of screen on time and ~20% battery. Now I'm getting up to double that.
One thing I can recommend is using MiFlash/Fastboot to do a total reset from scratch. Didn't really work for me, but you may be different.
Other than that, although it's tedious, you may have to install 1-3 apps per day after a fresh install to see if your battery holds at first and then dies sometime after installing certain culprits. It takes forever, but at least this helped me when I moved to Mokee to make sure that it wasn't any of my 'vital' apps that were causing me issues.
Best of luck!
Funny thing that the Mokee-Rom did SOLVE your problem. In my eyes this Rom was the beginning of my problems.

What is the difference to using TWRP?
I will try the Mokee-Rom tomorrow. Since I never used MiFlash/Fastboot before I won't use it until you tell me that there is a difference compared to doing a full wipe with TWRP.
I tried flashing the Mokee-Rom again but the problems go on. I installed very few apps and the battery is still very bad. Today I had 18 minutes of SOT and though I lost 14% in a few hours. This time it was caused by Whatsapp:
It always seems that some apps just don't like to stop doing something but it's random which app is the problem.
I am totally running out of ideas so please help me guys!
I'm on Mokee and satisfied with battery, this rom have less problems than other (for me). First of all i have installed MobileRadioActiveFix with xposed, then SmartNetwork to turn off wifi while my screen is off. I've got few other things but right now i've got over 4h SOT so it is not bad score.
i have the same problem! it happens with flashing severals ROMs (mokee by bule?) and starts battery drain with all ROM, it never goes... is not the battery, the cable or the rom..... i dont know im disperate... the sot changed from 4-4.5 h to 2-2.5 h... with all ROM, please help us and sorry for my bad english
Well i had situation that my SOT suddenly got down but i was still on march rom. After update to latest version without wipe it is ok right now.
Have you tried with wiping all with internal memory? Maybe something is there still and that is making a problem.
Another thing that came to my mind: have you changed build.prop and have copy of it? If so, delete it. I had some problems becuase of that.

every rom i have flashed was a clean install (full wipe of internal) after latest miui update, when the phone shut down at 0%, i put off the battery for 10 min, after i put back and the phone was at 19%!! now is on charge... maybe the problem is solved.. i will post if it is solved (sorry for my bad english)
I had that problem with earlier phone and it drived me crazy. I was not able to find what was the cause unfortunatelly. Phone was given to service point to install branded rom (it was not available for public). Right now i do not have problems like that, if i have some i'm able to find solution somehow. Although what i wrote helped me when i saw SOT problem.
problem persists... is there a method/app to calibrate battery that works?

Not that I know of. I`m facing the same issues like you here.
You can try:
-discharging until the phone shuts off
-charge it in OFF mode until its full
-disconnect charger, put battery out and in again
-connect charger, charge it to 100% again...
repeat until it shows 100% when connecting the charger.
For some ppl this seems to work.
Please let me know if you find out something!
There are lots of ppl out there with exact the same issue!

EDIT: Installed PSYROM V3 for testing purpose right now. Lets see how it does with skynet and a freshly calibrated Battery with the internal calibration tool of the rom. I`ll give feedback on monday.
Update to my issue:
-I did a full wipe (including internal memory)
-Installed PSY ROM V3.0 and Skynet
-Wiped cache/dalvic
-Startet the phone, installed my apps etc
-Charged it to 100%, waited 20 more minutes
-Did the Battery calibration with the internal calibration tool (everything is described in psy mans thread)
-Did a reboot
So far there is no Battery Drain, after the (long) reboot, wich took around 5-10min because miui is optimizing apps etc the phone came up with 97% and stayed there for almost an hour now.
I´ll give you guys feedback next week. Hopefully we get this sorted out.
You can try Angels & demons ROM v8.0 it is providing me with great battery life, so much better than stock or stable version of MIUI. I use Gsam battery monitor, and I have not faced that issue so far.
