[Q] Weird battery drain

Ok guys n gals, here's a puzzle for you all.
A few days ago, I noticed that my standby consumption had gone from around 10 mA to around 40mA using mobile data but with all other radios and GPS off.
For testing purposes I disabled location services through wireless. No effect.
I have tried with several Froyo and Gingerbread ROMs and the results are identical.
I have also tried with different radios, flashed using both fastboot and recovery.
I have used the ROMs without settings or app restore and I haven't installed any other apps than those included in the various ROMs. Additionally, i have tried various kernels.
Using Airplane mode shaves of a couple of mA.
aLogcat isn't showing any weird lines, mostly garbage collections.
I have tried searching far and wide and I have tested freezing various potential culprit apps using titanium backups' freeze function and all the battery calibrations/fixes I have found, but nothing helps.
At the moment I am using Oxygen RC6 with their recommended radio 5.09.05.30_2 and I am still seeing the same issue. The phone has gone from making it almost two days with moderate usage to barely a day with little usage.
The phone is S-OFF and I am using the N1table.
Can anyone please help with this? Apologies if this problem has been described before. I really tried searching before writing tis, but it could be that my search fu is weak.

Have you found a solution? In my case i'm getting ~100mA with the phone sleeping... and I can't seem to fix that.
Oxygen2.0-RC6 here.

Yeah, did that. No joy.

Maybe i'm totaly off, but, do you use Facebook app v1.5 ? If so, that's one power drain app because they messed up with new chat feature.

To anyone in Japan with horrible battery life, this might be helpful!
Solution for battery drain:
Just found this japanese guy who had the same problem with an Oxygen rom.
http://d.hatena.ne.jp/majadroid/20101223/1293094736
He explains what he changed in build.prop and has packaged it as an update here:
http://www.multiupload.com/5EAK6IUSQR
I am flashing it now and will report problems (or success I hope) in a while. According to the OP he managed to get to 1~2% hour drain which is very promising.
EDIT: It seems to have worked!!! I am back to about 10mA with screen off!

Thanks for all the replies.
The last thing I tried was a total restore using a HTC RUU, so I am now S-ON
This didn't help much though, even if I was down to 27 mA on some occasions, maybe that's normal for HTC roms
I have rooted it again but not S-OFFed and I am running the latest CM7 build (#12).
@TheGhost1233: I have tried the wifi sleep policy.
@m4dm4n123: No I don't use facebook app. Additionally, I have tried removing as many apps as possible only keeping some google apps and currentwidget.
@slyn4ice: Thanks for the tip. I have just flashed it but I am not noticing any big difference. I am seeing a few mA:s reduction, but still far from 5-10 mA in standby... I'll let it run for a day and see if it improves.
I am still open for suggestions...

[ISSUE] Problem with battery drain with mobile network ON(WCDMA)

I get a very huge battery drain with MOBILE NETWORK ON and WCDMA/GSM
EX : today i had 42% battery, activated MN for 15 min and browsed for like 5 min on some sites(no DL) . After 15 min , my battery droped to 28% :O which i found very weird, since it was some small navigation...
Is this normal ?
AND
WI-FI is normal regarding usage, and standby batter drain is like 3-4% on 8 hours

The Desire HD has very high battery drain and when on 3g it will search for coverage. Try new radio and new light rom

Try to turn off 3g when u don't need. The gsm mode have 5-8% gain of energy, perhaps change your radio too.

hello,
i have big problem with my HTC Desire (rooted with custom ROM). Before 2 weeks my Desire worked perfect: battery drain full after 3-4 days, network signal was good. But now battery drain full after 8-12hours, and i have problem with signal. At home signal was good, but now signal is low. And the phone reboots 1-3 times a day. All problems start in the same moment.
When I switch Desire to Airplane mode or to only gsm or 2g mode battery drain normal.
I tried factory reset, install other roms, other kernels, newest radio, 2 batteries; 2 sim cards; scan with 3 different antivirus (no virus), format /boot; /cache; /system; /sd-ext; /data and install new ROM but nothing help me. I don't found nothing about it in Google. Maybe it is hardware problem? Maybe someone have some idies?
I bought another HTC Desire and he work perfect at home and other places. Now I can compare with faulty Desire, but I don't know what more can I do.
Sorry for the English mistakes

Repair is very expensive.

CM 10.2 for P930 discussion thread (Official nightlies available for download)

Having issues of never finishing booting (stuck on cm logo) after I install apps and restart. Works flawlessly on a full wipe/install until I restart my phone.

No major issues for me so far. One reboot, but not a big deal. So far so good.

What about performance?

How's battery life on this rom? I'm getting very little drain when the phone is in sleep mode with Avatar and wind kernel. In daily use (wifi and 3g data), battery seems worse than HoNo roms.

Guys this is the first release so i don't think it will be on par with a mature 10.1. But seriously try it, its pretty stable and the more people running it providing feedback, the quicker its going to get better.
Sent from my LG-P930 using xda app-developers app

This ROM is pretty stable. I have had it for about 24 hours. I have had 2 reboots. First it was when I enabled Developer Options. The second was when I was trying to restore from Titanium, listen to music, and browse the internet at the same time. That should have probably been expected.
The battery life actually seems okay, but I am testing that today. I'll report back.
I will report more as I use it today.
*EDIT*
It also freezes for a few seconds when I enable settings some times. Nothing consistent. I just wait a few seconds and everything catches up.

Couple things: First of all 8/27 appears to be broken. When I installed from 8/26 - 8/27 my mobile network stopped working. My phone showed a red x under signal strength and under signal status my imei showed as unknown as was my APN. In fact it wouldn't even save my APN when I tried to manually install, but WiFi worked. I went back to 8/26 and everything worked again. Has anyone else tried 8/27?
2nd: on 8/26 WiFi bug seems to be back, turned on or off it constantly drains my battery, and the battery stats shows it on continuously.

I had tested Nightly from 08.26.
It is mostly stable. I hadn't any reboot. But i had used device as phone and to get some mails. Didn't launch gaames and etc.
Interface speed is better than 10.1. But overal benchmark score is lower( antutu with 10.1 - 7500, antutu with 10.2 - 6300)

[Q] HELP cell standby huge battery drain[tried each n everything prb still persists]

hey guys...
i have tried everything to stop the battery drain
switched to many different roms
under-clocked processor to 768mhz
set a black wallpaper
brightness set to minimal
did battery calibration
switched of all background processes and made sure no location seeking programs works.
used CPU spy, the cell does go to deep sleep
tried juice defender and deep sleep battery saver
but nothing seemed to work
phone locked on full charge drains 40 to 50% in night without using.
then after a few days later i restored everything and opened airplane mode and I went to sleep, in the morning the battery didn't went low a single percent. battery health is good as works really well on airplane mode.
i have low signal issues but i get text msgs and calls with no problems at all, and my explorer and s3 seems to perform well
my all type pf connectivity is off example: location access WiFi Bluetooth etc only gsm is working, i manually selected the network and set it to gsm only rather them auto from *#*#4636#*#*.
what shall i do??
i searched and tried many things from the internet.
i really want those calls i cant always be on airplane mode, the problem is 200% of the antenna draining juice to get more signals. please help.
is there any way to stop the battery drain or restricting the antenna to consume less juice?
PS:using cm10.1 by nightly version:19 Aug 13.

anyone??
one thing more i installed better battery stats it says
no or unknown signal
no data connection
and it is running continuously like since i installed betterbatterystats.
where can i get this bug?? or disable this service??
please give a detailed explanation.

There are a few good apps to try I use
battery mix (I think this is one of the best) and wakelock detector both from my the market.

Battery drain
I´m having same problems with my DHD, currently im using 4.2.2 Samsation (was it named like that but anyways 4.2.2). Without using phone it still drains 40% in few hours.. I got replacement battery from eBay and thought that would help but didnt help at all. I´ve tried different roms but would like to have newest roms without battery draining so much, so could someone share how to get it better?
And about changing radio, was there a possibility that you may brick ur device if installing wrong radio?
Thanks already!

and regarding the radio if u do it right and reasearch a little u wont brick it for sure. got my radio from here:http://www.icsforums.com/forum/showthread/26951

yup there was nothing, no wakelocks etc i even underclocked my processor to 768mhz... the thing is the signal reception cause when i turn the cell in airplane mode and leave it over night the battery doesnt goes down a single percent. it acts solid.
i get around 18 asu signals at my place i check it from *#*#4636#*#*
but the thing is i was using an HTC explorer before switching to desire hd and with the gsm mode(no airplane mode) the battry stayed solid like the desire hd one with airplane mode(didnt dropped a single percent) at the same house same place.
dont know what going on.

Well try to wipe all data.
On the stock 4.3 i`m averaging 4h30m display time with 18h of up-time and 15% battery left.
I have: H+ on all the time, WIFI on all the time and location based on WiFi, auto-brightness on max level, Sync on.
Some app may be draining your battery or the battery may be close to it's death.

I tried wiping and factory reset, then I am not only on plain vanilla stock rom and whatsapp and chrome that's all.. I am having problems even with my zero lemon 9300mah Battery that is draining too fast I used to get 3-4 days easily but now it does last even one day.. Also my h+ disconnects and takes time to connect once I switch on the screen.. Any suggestions as to what can be done is it that the Handset motherboard might have messed up?

: Go to settings> data usage> press the menu button of your phone and tick the restrict background data. That's it! You will have a triangle notice on your notification bar but your problem will be solved. I hope it works for you too. If it does not work completely to your satisafaction also disable the great battery drainer Google+. It is usually the main reason for the drain among others.
