Battery drain on MIUI 5.2

Hi guys, I've flashed MIUI 5.2 yesterday and I didn't have time to play around with it. But I've noticed today that even when left idle, the battery drops from 100 to 84 in about 2 hours or so. All the other services are off except 3g. Plus when I fiddle around with it, the battery drop is even more noticeable. I went from darky 10.1-Miui5.2, just fyi with the default kernels on the miui page. Any suggestions on how to fix this?

Miui is to heavy
If u want longer life then Miui aint for u.
Miui is by far the best rom for galaxy s ever if u like to be able to change every aspect of ur phone but the more a rom can do the more juice it takes.
If u want more life and less tweakeblity then u need to use pony roms like darky or ultimate aso.
Edit : Miui bat life is slowly increased by each release (5.2 is way better then 4.1)

Yeah I've noticed that. I switched back to Darky,happy to see 16hours of battery life again. But I wouldn't hesitate to go back to miui in the future though, provided the battery life increases. Or at least until juicedefender has some effect on it

flashing from stock to MIUI is a painful process and it reflects on the phone too !!
after such a vigorous beating from ODIN and Recovery flashing, the phones battery needs time to settle,
Do the battery calibration a few times, generally the battery will settle after a week, Until then its hard to judge battery life, albeit it is definitely less than a stock ROM, But some MIUI users report 1 day, some report short of 3 days..
so dont give up just yet

wow 3 days? imma try it again then, right after my battery finishes charging. what kernel do you think is the most ideal one to use? i live in the uk
Edit: I saw a guy getting 14% loss after 12 hours using JXJV6. Isn't JXJV6 a modem for the middle east? Is it possible for me to use it here in the uk?

im not sure about that modem, but i dont see why it wont work, i use at the moment ZSJV5 - i am in the uk too, that modem works fine for me .
As for the kernel, the latest Glitch V10 is good enough, you could also maybe undervolt and underclock just a little, this would increase battery life too.
but 2 -3 full cycle charges really makes a huge difference.

Awesome, I'll try that soon. Mind sharing the link for ZSJV5? And the app for undervolt and underclocking?
Edit: It seems that I have the insufficient storage space bug, I've read the faqs,
1.3 Apps not installing - Not enough memory message pop up (Known bug for CM7/MIUI)
1. (Using root explorer or any equivalent app) Delete folder /data/data
2. Copy "folder" /datadata to /data/
3. Change name of folder /data/datadata to /data/data/
But it still doesnt work. If I reboot, I have to go through the setup wizard again, and rootexplorer will be uninstalled. Any idea how to fix this as well?

[Q] Piss poor battery life with Serendipity 7

I am having a horrible time with battery longevity. I even tried replacing the battery, to no avail.... i think it just got worse. I'm running S7 build 2 kernel 4.1 and basically, at idle, I have am estimated 6-10 hours battery life. There's absolutely no way I can make it through a day of even 12-14 hours with my light usage pattern. God forbid I actually use my phone, because if I do, it just goes south from there. And let's not even get started with angry birds... I'll get 30 minutes to an hour of gaming before it drains the battery completely. I've re-calibrated, deleted batterystats.bin, cleared the dalvik cache for good measure, prayed to various gods for intervention, and nothing has made an ounce of difference for the better. Any ideas? I've even re-flashed the rom several times... just to make sure I did everything proper. Also, is there a way to lower the minimum brightness of the screen? according to battery usage, it's what's using the most battery by far.
Finally, Why is there a listing called "Android System" (using almost as much battery as the screen!) when there's another listing called "Android OS" down a few? Shouldn't they be the same thing?

Not when the only pertinent information it turns up is "reboot your phone" trust me, I searched before I posted, and didn't find jack. That's why I posted here.

So... it's a gingerbread problem, which means my options are basically "flash a rom that isn't a total battery whore", or "live with it"? because that's what it sounds like. I like serendipity 7 and I love gingerbread but frankly I'm getting sick of flashing roms and losing all my app data, text messages, settings, etc. Especially my home screen layouts, to the point where I would almost just rather run out and get an atrix or nexus S than fiddle with it any longer. But, that's probably not an option right now unless I find one really cheap.
Edit: Btw, battery left widget is estimating i have 5 hours 30 minutes left on A FULL CHARGE /facepalm

no its random. Most of the times rebooting your phone will fix it. Others you need to reflash full wipe to make it go away. But ya either flash a 2.3.4 ( i believe it got fixed past 2.3.3, though not sure) or play with it till it behaves. When ever my phone shows android using more than 10% i reboot just to make sure. Course I end up rebooting every 2 days or so because I like flashing themes and what not etc. xD

my phone boots up already using more than 10%. i guess i'll just wait for mikey to update to 2.3.4... should be soon enough (http://www.wowwiki.com/Soon for a good laugh) It's not really worth it to fiddle with for me at this point, since I'm already eyeballing my next phone. I just want it to make it through the day... but I guess that's what spare chargers are for.
Also, is the fact that it shows android system and android OS weird, or is that normal?

Problem w/ battery reading n charging

hi all,
Ive recently upgraded to v10d (Europe Open, coming from v10b) and im experiencing some wacky probs with the battery. Yesterday noon i charged the phone to 100% and then unplugged it and left it for about 5h. I then checked on battery life which was still 100%(!). I rebooted the phone and after some heavy use (2-3h youtube, lots of surfing, new widgets installing/configuring) i had dropped the battery to a 60%. I then went to bed. This morning the phone was dead and when i put it on the charger i saw that the battery had dropped to zero causing the phone to shut down. So i plugged it in, and switched it on. Since day 1 i was surprised with how fast the phone was charging to 100%, so after about 45min i checked on its state and saw that it was still at only 6%. I checked again after half an hour or so and it was still at the same point, 6%. I rebooted the phone again and checked on the battery level b4 plugging it back in and i saw a reading of 76% (!). Now ive plugged it back in, and once more its stuck on 76%. In all cases, even though the charging battery icon is there, the phone doesnt seem to show any changes in the battery state. Has anyone experienced something like this? Any advice welcome
Peace

I've got the same problem. It started two days ago, I tried Battery calibration but nothing changes.
My rom is miui.
Sent from my Optimus 2X using Tapatalk

Not only i get crazy readings, but the battery drain is MASSIVE. The phone sucks more than 60% battery in less than 7h on idle.. I dont get it, i did everything using LG's update tool, chose Europe as a location (The phone was sent from expansys UK, but i live in Spain.. Expansys 'out of stock' solutions). At least i dont get any BSOD or lags.. But the phone is still uselless like this..
EDIT: Ignore the sig

Have you tried battery calibration? (market.android.com/details?id=com.nema.batterycalibration) I think that's the problem, I did it again yesterday and I've got 20% of battery drain in 8 hours. Maybe too much (it has been in airplane mode 6 of those hours) but nothing unusual.
Sorry for my english, I'm from Spain too

I didnt try Battery Calibration because ive already done what the app does manually. I deleted battery stats from CWM, drained the battery, left it full charge without interruptions and the problem remains.. Im waiting for the phone to fully charge now, ill switch it on and post bb and ril readings because i remember that even though getril stated that BB and RIL are matching, it said something strange about a T-Mobile ROM or something.. Ill be back with more

OK, here's what i see from GetRil, it looks a bit strange. On 'about phone' (Android menu) I see that im on LG version v10d. But on GetRil i get:
RIL: 0405 (V10C, T-Mobile)
Baseband: 1035.21_20110405
Can anyone make something out of this?
Any help appreciated
EDIT: AGAIN Ignore Sig (Got to get this done at some point )

I tried battery calibration, but it didn't get better. Then I deleted battery stats but didn't work, so I tried battery calibration yesterday and (for now) it's OK. Maybe when I charge it again the problem will be back.
I've got bb 622 and ril 622 v10d vodafone and getril says everything it's OK
Edit: you should try another ril, V10C Spain for example.

What version do you have? v10D? Did you update the phone using LG update tool?

I use Miui (It's a rom based on cyanogen) and I flash a new one almost every week. Those roms are beta, so it's "normal" for me to have problems, but you shouldn't have them with a stock one...

yeah i guess so.. The thing is that im coming from a much simpler to use/flash smartphone (acer liquid) and im a bit mixed up now.. basebands, ril's etc. Maybe i should try to flash the last version for spain using the LG tool, and try again.
EDIT: Now im getting a 'Update not required' message from LG update tool. Probably because its trying to go from v10d (Europe) to v10c (Spain).. IM SO ANGRY!!

I would do that. The last bb is 725, it works well for some people, but not for me, I tried it but the battery drain was massive, so I get back to 622 and (until this problem) everything worked fine.
You'll get used to this, it's funnier

How do i update the baseband only?
EDIT: I found the baseband page on Modaco, where its got the smartflash tool/drivers and the BBs, but it says that it will fully wipe INCLUDING Int SDCard. I try to do a backup using CWM-based Recovery 4.0.1.5 for Internal & External SD Card from http://forum.xda-developers.com/showthread.php?t=1098745 but even though i have an external SDcard in, it does the backup on the internal!

With smartflash (http://android.modaco.com/topic/335494-12-aug-smartflash-stock-baseband-release-103521-20110725/) but read everything very well. It'll delete all your data, so make backup. If you want help with that or something else (and you speak spanish) ask here: http://www.htcmania.com/showthread.php?t=217920 and I'll help you. I don't dare to do it in english, in case I don't exprese myself well enough

Ok man, thanx. I was wondering if it is ok to flash baseband 622 over v10d, or if it is totally irrelevant and i just dont know what im talking about..

I'm such a noob too (specially talking in english) but if you ask to the experts, you'll be fine, good luck

BB and rom are two separate stuffs. U can play around with any BB till u find one that suits u best.

Yeah I realised that.. Im on v10d and i just flashed BB 622 and preparing to flash Fr19.. Lets hope that all the battery craziness will go away..
PS All this just when i read that 'Gingerbread Is Out' post.. damn it..

Since last flash I have had absolutely bullsh!t awesome battery usage :-) *READ*

Ok...this is going to sound completely outrageous! It seems outrageous to me even I have never had this good of battery consumption ever! The phone was purchased 16/08/10 and has retained the standard battery all this time and had various Samsung ROMs on it. Mostly DarkyROMs that have improved battery quite considerably. It currently has its first stable ROM of ICS since I started flashing ICS from just prior to RC1. The ROM is a bit of a mix-matched frankenstein build of a ROM by me originated from MyICS and OneCosmis RC3.1. I have recently experienced allot of issues (including very poor battery drain) prior to this last flash and so have many of my users...actually most jumping **** (and I don't blame them).
My last ROM flash seemed to stable and go through perfectly, I was running with my own 2.0.1 and was about to release this ROM (that I'm currently on from a system dump) as a 2.2.0 version update for everyone else.....however I have held back because of the announcement of RC4.....so any of the improvements I haven't released. The install procedure backs up battery stats so as not to need re-calibration and has done so for the last 3 or 4 install. I am running the latest platypus kernel made for RC4 though
Anyway the last time I had my phone on any decent charge 22hours ago. It's currently 10.40pm EST and phone went on charge about 12.30pm lastnight. Since then I have had data left on (something I wouldn't normally do...I was used to renaming APN prior to ICS) and wifi on* (granted I have latest Juice defender ultimate)
*set to trained locations to auto-on within 250m of known wifi access point and disable 3G when wifi connected
I have gone the whole day today, with a small amount of internet (damn genie widget gets me every time with cool interesting things flashing up on the screen lol) and moderate phone usage; texting and a hand full of 10-15min phone calls....nothing out of the ordinary.
I plugged the phone to USB to transfer some things from work and it was plugged in for approximately 15-20seconds. I use multi-mount SD card app (I have included the lite version in my ROM) and allows for fast transactions and also to be able to use the phone whilst connected etc (read up about it). And I did the same here at home to transfer the things off again. It has remained sitting beside my PC untouched (unusual cause I like to fiddle) for the last 3 hours...and decided to pick it up and glaced at the battery 90%. Ok so I waited another hour and glanced again and STILL 90%.
Is there something weird going on here that I should know about? My phone has never been this good even if I left it completely on standby and in flight mode it would have eaten more than that! It seems almost stupidly impossible.
Fill me in on your take of this situation? Happy to do a complete system dump to try figure this sh!t out cause I made so many mods last ROM update I wouldn't know which one is contributing or if all or none?
edit: included more information

It's now 2:20am I am going to bed. My phone is 86%
A drop of only 4% in nearly 4hours. 1% per hour is not too bad

How do you handle synchronization, and why kind of tweaks do you perform with juicedefender?

heh i know what you mean
Im using as well icssgs rc4 (pulled) for 3 days, and right now i have 10% left after 29 hours of using my phone as wifi, downloading, sync, calls, sms and some music, all i can say is that rc4 +platypus kernel is the beast for the battery. my phone never lasted for such a long time, even on rc3.1 it used to die after 18 hours of being idle.

Reporting
7am 77%
10am 62%
10.55am - poor signal and market prompted to download an update for LinkedIn battery has plumited to 23%
36hours use and still 23% battery is pretty good. At least the resil
I will be making a deodexed version of RC4 sometime soon with a few extra bonuses ....however it won't be all that special as I have been giving away my secrets everywhere on the forum to help others on any ROM (not just my own) so anything included in my next release will be old news lol
Juice defender? Tweaks? I am not sure what you mean? You mean what are my settings?

Ok...wtf? Battery is climbing back up again now? That is something that has never happened before! Im on 26% again

realy ? ))

Offfical time of death 4.34pm EST. approximately 40hours after full charge. I am stoked with that.
Edit: I will be making a donation to Platypus Kernel right now

Can you tell which rom you had before flashing rc4 and another question are you experiencing any other problems with the rom like sd problems because im considering to go rc4 too.

I am still running RC3.1, I am just using the RC4 kernel
I am in the process of developing my own RC4 ROM based off this RC3.1 (my own version of it anyway) that is the first ROM I have that is stable. All versions of my ROMs prior to this have been very unstable. ROM is still odexed so that will be my first point of call and then repackage and get it up and running.
I am in the process of compiling some java code for wifi calling on vibrant though so I am too busy to even start on my ROM

[Q] [CM10.1.3] rapid battery draining with various kernels - help needed!

Hello everyone,
I switched my 16 months old 4x to CyanogenMod 10.1 about 2 months ago, and updated to 10.1.3 about a week after the release. About a week later, I had my first problems with rapid battery draining. I have switched kernels thrice, now running the most recent optimus prime for CM, and have tried fiddling with the values TricksterMOD provides, but I haven't found a way to get any decent battery life out of the device ever since. Last night, the battery drained 50% in about 12 hours of non-use (phone was left with display off in my jacket pocket, and that's not even the worst drain I witnessed in the last two weeks.
I'm running BetterBatteryStats to get a clue about the origin of this drainage, and can see that my device seems to me awake far too long when I'm not using it. At the moment, I'm looking at 44.6% awake, 55.4% Deep Sleep after 2.5 hours of not using the phone once (I was driving home from work half of the time). In "Kernel Wakelocks", I see "wlan_rx_wake" with 21:03 minutes on top, in "Partial wakelocks", the highest value is 20 seconds for "AlarmManager".
I have the usual suspects of communication/networking apps - Facebook (set to 2hr update), Google+, K-9 Mail, WhatsApp, plus AndroidWeather (set to 30min update) - and news apps which are allowed to send push messages. I use wifi, but no bluetooth. I never watch movies, play games or listen to music with my phone.
I have attached a BetterBatteryStats log from the 50% drain in 12 idle hours I mentioned. View attachment BetterBatteryStats-2013-10-17_092335401.txt
Can anybody give me any pointers as to what I going wrong here? I really would like to use my phone without having to plug in the power supply every few hours. If you need any additional information, I'll gladly try to provide it.
Anyway, thanks in advance for any help.
Cheers, Pit.

only 3 letters. O M G ! this battery report just made me like this face here
u cant flash kernels one after another. there are bugs this way. dont all kernels use the same names for files. leftover files will cause problems. do the whole procedure. go to recovery , format data, reboot to recovery and install new rom

You mean you cant flash Android roms one after another. You can freely flash kernels one after another without wiping anything, Its completely modular.

Not sure about the battery drain, it could be caused by a kernel, but its not because hes flashed multiple kernels.
some background:
Android kernels are packaged into boot.img's (these .imgs can be placed in .zips with instructions on how the custom recovery should handle flashing it) Inside a boot.img you will find a zImage (kernel) and a initrd.img (This stands for initial ram disk, its simply a basic file system that the kernel mounts, containing mainly scripts that handle mounting all the necessary partitions etc, then handing control over to Android. )
The boot.img is stored in a emmc partition (/dev/block/mmcblk0p*). When you press the power button, the bootloader is initialized , it then powers on necessary hardware devices, the bootloader than pulls the boot.img from its partition, extracts it and boots the zImage(kernel), which will start initializing less necessary hardware, but mainly mounts the initrd.img and runs the containing instructions.
Bootloader -> Kernel --------------------->
.........................Initrd.img-> ........Android
To move back on track, the zImage and initrd.img only operate within RAM, they only lie in emmc when they are achieved as a boot.img. When you shut your device down, nothing from the kernel persists in the next boot (maybe /proc/last_kmsg ), this is why you dont need to wipe anything on your device between kernel flashes.

Thanks for clarifying that; it saves me some trouble.
Does the BatteryStats log give any indication as to why the phone is awake half of the time?

Dont know, but maybe O Prime is one of these kernel which hides the xmm baseband wakelock.... that would be the missing awake time in your log

Is there a different kernel you would recommend I should try out? I selected the OPrime because it claims to be focussing on stability and battery life instead of raw power.
Furthermore, what would the baseband wakelock tell us in terms of how the fast drain happens?
Cheers, Pit.

Hello all,
just to try it one more time: is there any way I can get decent battery life out of CM10.1.3 on my 4x? This is my profile from today, where I unplugged my phone from the charger around 7:30 a.m. and didn't use my phone thereafter until 5:30 p.m. where the phone was down to 38% already (stats taken around 8:30 p.m.) . The governor is set to conservative and the max frequency to 1.1 GHz, which already makes the UI a bit sluggish. The other settings are unchanged from above.
Secondly, if there really is no chance of improvement under CM10.1.3, which ROM (and kernel) would you suggest for my phone, so that I can at least get a full 24 hours of battery life when I'm not using my phone most of the time?
Thanks in advance, Pit.

Format SD card and wipe everything before flashing new ROM. When I say everything I mean : catche - dalvik - format system - format sd card (sd card is 11gb internal memory of device and external sd card is your inserted sd card). Try latest liquid rom i have good battery life with its stock kernel.

Hi everyone,
well, that was a bust. After spending the better part of a day formatting and installing over and over again, I'm now running CarbonRom [20131023] - and having the same battery problems as before.
I tried LiquidSmooth (2.23), but I never got it to work properly; after installing I always got "application someName was teriminated" every few seconds (while the Play Store app was redownloading and reinstalling my apps, but also when I tried to activate SwiftKey, which calls the settings app at one point, which abruptly quits before I can type in anything. I then tried
ParanoidAndroid (3.99, which I didn't like UI-wise)
and SlimBeam (1.9, where the Google apps I downloaded as stated would install fine, but then not appear for some reason - at that point I didn't spend much time trying to fix it, because I was already fed up with it all)
before finally installing CarbomRom, which worked fine. Thus, after downloading my apps, I tried out my battery again. I unplugged the phone, turned the display off, and went shopping for about two hours, touching the phone just once for a few seconds.
The result is again about 30% awake time during these two hours, losing 10% battery in the process (BetterBatteryStat included). That is pretty much unchanged from my experiences with CM10.1.
What am I repeatedly doing wrong that I don't get halfway decent battery runtime out of my 4x (which used to run fine battery-wise for a year when I used the original LG firmware (which had other issues, but could last 36 to 48 hours, depending on usage? As I don't see hordes of 4x owners throwing the device against the wall in frustration, I must do something other don't. But I haven't got the slightest clue what that might be.
I will try PACman (nightly 20131021) next, but if anyone has any pointers, please please help! I'm running out of ideas.
This was my procedure, by the way:
Reboot into CWM
Format system, cache, data, sd card
flashing ROM
Rebooting
after bootup reboot again into CWM
add the Google apps
reboot again
After bootup, reboot again into CWM
just to be sure, reset to factory defaults
reboot, connect with Wifi and Google and start redownloading the other apps
Frustrated greetings, Pit.

Hi again,
PACman is even worse. First off all, the UI is laggy as h*ll; sometimes, it takes more than two seconds for a button touch to be recognized.
That would be somewhat tolerable if the battery life was better. But in 2.5 hours of leaving the device lying idly on my table (display turned off), more than 50% of the time, the phone was active. BetterBatteryStats are again included as an attachment; perhaps someone can find out what the problem is with them. At least, this kernel doesn't hide the xmm_baseband wakelock, though I have no idea what that means whatsoever.
This is getting ridiculous - is there really no way to get the phone to last more than ten hours (doing nothing with it - when I use it even for occasional browsing/e-mail checks, it's way less than that) anymore? Why is no one else having problems on that scale?
Typing this post cost 3% of my battery. And I'm typing it on my computer, not on my phone.
Depressed greetings, Pit.

Thanks, for the info, I will investigate that, though I haven't found this "wifi update of demetris" on first Google try yet, just recommendations what to do with your WLAN router and PC settings.
But I my second-to-last try - where I was out shopping - the wlan_rx wakelock wasn't the problem, rather the xmm_baseband wakelock, where I still am clueless as to what that means at all. I fear that getting rid of the wlan wakelocks wouldn't help my general problems, just the problems I had at home last night in my last try.
Furthermore, if I can use the phone only by carefully switching off and on wlan manually whenever I leave the house, the phone will become pretty much useless to me. Yesterday alone, I forgot switching wifi back on twice. That way, either notifications would go through mobile data connection or not happen at all.
I will reflash my device again this morning - as the PACman UI lags are unbearable for me - and see what I can do about the wlan drain. I cannot reconfigure all the wifi networks I connect to, as some of them aren't mine to configure.

I tried that earlier today, and the LiquidSmooth 2.9 (Android 4.2.2) installed fine by your instructions. But it didn't help at all with the battery usage. Phone is running on conservative governor limite to 1 GHz, and I even tried the Broadcom Wifi Update mentioned here earlier (otherwise, I'm on the LS standard kernel).
It all doesn't help, the BetterBatteryStats are still full of wlan wakelocks (even though I switched to static IP as someone mentioned that might help). Result: 10,8% battery drop per hour of leaving the phone with display off on the table.
Before I flash another ROM for the 14th time this weekend, I will collect some results with wifi turned off. Not that that would be a feasible option for me, but I want to get to the bottom of this.
Cheers, Pit.
