Hi all,
I am using CM7.2(FXP106) on my Xperia arc, with the kernel that comes with it. But I find out that battery drain is much more worse than the stock. 42 ROM. I usually charge the phone to 100% before I sleep, and the phone only uses 3% during my sleep with stock ROM. (stock kernel, cpu is downclocked to 768MHz when screen is off, using conservative governor.) However with CM7.2 my phone consumes more than 10% during my sleep. I also downclock the cpu to 768MHz when screen is off the cpu governor is smartassv2. In battery usage, mobile standby and phone idle consume the most. lol (It used to be display with stock rom) Is there any possible workaround? thanks a lot.

ok, i try to give you a view points to check:
read and install this on your phone. I had also a battery-drainer on my phone. i found it and now i´m happy
One time, on my x10miniPro the facebook app drain my battery.
Have you clear dalvik-cache before you install the rom? full wipe?
I installed many custom-roms at my x10 miniPro. Sometimes i have also fast battery drain. Then i made a second time a full wipe, clear dalvik cache and install the rom new. This fixed most of the problems.
try this and report
I had the same issue, but they closed the Issue at the project-page:
http://code.google.com/p/freexperia...tatus Priority Milestone Owner Summary&id=155
for this reason i changed to Arconium, and.... 1% during a whole night in flight mode, with FXP it was about 10%!
i really miss the additional settings from CM7 but as long as this Problem exists , even if they say its normal, i wont switch back.
I had exactly the same problem whith CM7.2 FXP107
It was "Cell standby" (I'm not sure it's how it's called in english) that was anormally draining battery. It may be linked to baseband (I was using 64 one).
I had wiped everything possible before, flashed with CM7.2 kernel.
So I swiched to Arconium 7 + DoomKernel 0.18 + baseband 36 with patches. No problem since.
I don't know where the problem came from, it didn't took time to investigate, it was to much of a drain to keep my phone like this.

i also tried Baseband -36 and -56 no difference, Full Wipe Battery Calibration and so on, but nothing changed.
There is no excssive battery drain on CM7.
Flash latest kernel, try different basebands, calibrate the battery sometimes (correct calibration !) and you won't have battery drain anymore.
I lose about 1,5 % in deep sleep and about 5 % with heavy (e.g. streaming, gaming).

PM me, I work at this very operator (in IT Outsourcing, but company is company).
EDIT: There you go (instead of xRecovery use CWM).
If this doesn't help either, here are more options.
ooidort said:
STEPS:
1. Download and install xRecovery from here.
2. Charge your phone to 100%
3. Turn off the phone and boot into recovery
4. In recovery, go to Advanced options --> Wipe Battery Stats --> Yes
5. Take the battery off
6. Insert the charger chord
7. Put the battery back and wait for the phone to boot
8. Once the phone boots up, you will notice that the battery percentage is around 88% instead of 100%
9. Charge the phone back to 100%
10. Repeat 4-5 times, seems to be the sweet spot
11. Enjoy your hopefully better battery life and report!

Thx for the Guide , but this doesnt work for me, once i had 82% after the first reboot , but now my phone doesnt boot automatically when i re insert the Battery, there is just a charging Symbol. when i boot manually , i have 100% battery.
You can use Toggle 2G with CM ROMs, pretty good in saving battery, you can set data to switch to 2G after certain minutes after the screen is off.

friends, I tried to solve my desire's 15 battery shuttown problem by installing the custom kernel as mentioned in http://forum.xda-developers.com/showthread.php?t=1534892 on my CM7 ROM. Howver after installing this kernel, I'm unable to see my wifi network while im using my laptop to write this post on it....any help to solve....i still wish to solve the 15% battery shutdown problem.....many thanks in advance
Well, I tried it a few times myself using the same link and different ROMs. Didn't work for me. Gave up in the end. I'm just aware that my phone shuts down under 20%. Don't make a mistake thinking that it will extend you battery life - it won't. :banghead:

That's a Sense kernel. That will never work on an AOSP rom like CM7.

I knew it wouldn't increase my battery life....but it could atleast give me the right warning...sometimes it switches off at 30% while i was saving the remaining 15% for a few important calls I might even get fired becos of this

You can try ManU Kernel which is one of the popular kernel for CM7
You can try this procedure to calibrate your battery. Personally I don't care much about it anymore and doing the procedure can sometimes be a hit or miss that it's a complete waste of my time. I get the usual battery runtime for my phone so I just remind myself that at 15%, my phone shuts down.

I've found out that I get no deep sleep after a full charge until a reboot. Running Jedi v.6 with faux008 kernel. Its fine without a full charge though. Can anyone else confirm this? I've tested this twice now, overnight charge, unplug cable, reset CPU spy, then turn off screen. I then wait like 30 min and check CPU spy. Doesn't go lower than 384 MHz.

I am running the same ROM but with Faux 009 kernel. I charged overnight to 100% battery and my phone has been off the charger now for almost 5 hours. It has been in deep sleep for 94% of that time or 4hrs 45mins. Currently still have 92% battery. Sleeping like a baby for me.
Also, the CPU Sleeper is already implemented into the ROM. Maybe see what app, if any, is keeping your phone awake. You may also want to give Faux 009 a try, I never tried 008 TBH.

Make sure that you exactly followed the instruction when you flashed the rom. Always full wipe, wipe everything, Do not restore data, let it sit for 10mins before the first use. My advice is you should re-flash the rom.

When you finish flashing and reboot the phone for the 1st time, just let it sit there for 10mins, NO TOUCHING. After 10mins, you reboot the phone and begin to sign in/set up ur phone.

Just out of curiosity, did you run a Jelly Bean ROM before flashing this ROM?
I have the same problem. it needs a reboot after a full charge to be able to go into deep sleep. I'm giong to flash faux v9 to see if it will solve the problem. Plus I might just update to jedi v7 while i'm at it.

Not to hijack but my phone does same thing. I have stock charger/htc/ even the usb in my car it does it with every one. It can go In to deep sleep - plug it in - unplug it and no more deep sleep until u reboot.
Hmm..well I had a suspect app, but eliminated that as a possility. I do in fact use several different chargers, so I'll have to test using the Samsung one. Several minutes charging test and it still sleeps fine, so I'm not really sure if it needs a certain amount of time charging or the full 100%.
Also I'm coming from stock ICS, rooted to Jedi rom.

Thank you for this info. I just spent some time testing. Indeed it's the charger(cable type didn't seem to matter). I had read somewhere from TDJ that the kernel knows what type of charger is plugged in. Either stock @ 1000ma, USB @ 500 ma or "unknown" @ 450 ma. I'm assuming this is for both data comms and phone protection, but surely this is a bug. The Samsung wall charger must send some type of id code to the phone. Crazy
I'm wondering if this can be fixed in kernel code, or does this effect all devices? Maybe a easier dirty fix with an app that clears charger type status could work. Unplug cable, then wipe status. Obviously this status clears upon a reboot unplugged..that's when I regain deep sleep.
Also, I can get sleep back by just simply plugging in the samsung charger for roughly 5 minutes..I was wrong about needing a full charge. I tested in 5 min intervals..that was enough. Sorry for the long post

I've tested this and found to be true. I use the original charger and work and when charged, it goes into deep sleep. but using the htc charger at home, the phone does not go into deep sleep, which drains my battery really fast. It just needs a reboot.
I hope other devs sees this and can fix it within the roms.

Yeah, same here. I'm on Jedi 7 which uses Faux 009. If I charge to full and just unplug, I never get into deep sleep, just 384 MHz until I do a reboot, at which point everything is fine with the world and the phone sleeps like a baby.
so i've been looking into this deep sleep issue and found this blog. I tried it and it works wonders. I know its for the galaxy note, but its the same idea for us. please read the whole thing including the comments. it might help some of you with deep sleep problems:

Hi guys.
I have a strange problem. My Gio charges from 3% to 100% in 3 minutes. It says fully charged...
Of course it's not real charging, if i unplug it, and start to play a game or just see my mails with wifi, it consumes that 100% on 5-10 minutes...
I've tried to charge the phone all night and the result is 2-3h of working time. If i use power consuming apps, like games, than it's just half an hour... I think that the phone stops somehow the charging process if it reaches to 100%.
I've tried to calibrate the battery, with program from market, and wiping batterystats from CWM too... It didn't help...
The strange thing is, that last week it worked well. Now something happened and it's ruinig my life...
I had THIS ROM when it started.
I've changed to THIS ROM, and it didn't solve the problem. All caches were wiped during flashing...
Any ideas?
Thanks for any help!
Anybody? Please...

Hm you said you tried to calibrate the battery so it`s weird. I have sometimes the same problem but after a calibration it is fixed. I can only recommend to charge it overnight , make sure you`re not overclocking it , make sure you don`t use wifi , mobile data , gps , see if there`s an improvement keep it only with calls and messaging for 1 day see how that goes. Check also the battery maybe it has a spillage altough i don`t think that`s the case. Sorry that`s all i can say
Thanks for the advices.
I've just set the CPU governor to smartassv2. It was on Ondemand. Now I can discharge the phone with playing within 15 minutes. It's better than it was on ondemand...
I will try to use it like a regular phone, let's see how it works...

I've a battery old as yours (04.05.2011)
With any custom ROM my battery life is of 3 hours...
With stock is kinda 5 hours with 2G connection activated.
I'm waiting for a new battery, but if you want to keep your phone alive up to then:
- flash a stock ROM
- install as few apps as you can (I've G+, Stream (FB client), FB messanger, Viber, WhatsApp, App Cache Cleaner, AppZorter and xda app, nothing else T_T)
- do NOT use kernel different from stock
- hope you good luck because first times battery will be strange, after some full usage and discharge now I've the battery life I told before
Hope this could help
I have galaxy gio and it problem is whaen i charge my galaxy gio 3 min later to touch to 100 percent and then i plug out and on it then it show battery is zero
its finally stabalized with bluetooth working, it gets decent battery, great performance, great features, you can add wind kernel 2.0 RC1 to improve battery life if you want.
so far no bugs, haven't tried mhl yet it has never worked on CM for this phone as far as i know though so prob still down, will report back later when i get a chance to try it.
with the said setup above i'm getting roughly 3 hours of video playback on 200 brightness (with wind kernel) when the test is done i can post exact numbers
3h 13m on 200 brightness running video playback
the results are posted on page 46 of wind kernel thread.
http://forum.xda-developers.com/showthread.php?t=2119976&page=46
It is incredibly stable too. I haven't had a crash, reboot, SoD or BSOD yet.
What is the best configuration kernel for this rom with wind 2.0rc1?
my phone is P936
Just stopping by to agree, since the RC2 release (I'm running nightly 5/11, day after RC2 release), my Bluetooth connections are working, my battery life is better and I haven't had to pull the battery to reset since.
ive had the odd random reboot now, not horrible though. the only other issue i'm getting is oddly high battery pull from WIFI but if i turn off wifi it's it's fine, i'm trying to figure out how to fix it now will report back, i can currently get 7-10 hours out of the phone with moderate use if i turn off wifi, i still think the battery can be better but it's workable for now.
the wifi issue worked itself out after some time, i'm getting 9-14 hours of use right now once i get a good setup i'll post it with some stats

anything over 12 hours i consider good.
There is a weird bug onde the CM kernel for RC2 that may prevent charging when the battery is depleted and the phone is off.
Installing the latest wind kernel fixes that problem
Sent from my Nexus 4 using xda app-developers app
i actually learned about this today it happened to me, and it doesn't prevent charging, just the battery screen doesn't show up so you think its not charging, also you have to let it charge for 5-15 min then pull the battery, then power up the phone unplugged to get it to turn back on. i learned the hard way.
Maybe it was a coincidence and my battery just died, but I left the phone charging for 2h and the battery just didn't work.
I will check with another one to make sure
pull the battery, put the battery back in, plug it in for 15 minutes, then unplug, pull the battery again, put it back in, then boot ur phone and charge it while on.
it was probably already frozen when u left it charging, if the above doesn't work then u might have to look into more serious methods like trying other batteries or seeing if you can get into download mode to flash a new kdz and start from scratch (if u think the rom is causing it)
