[Q] battery life horrendous! help please!

ok so this is my situation, i have flashed nearly 3 roms in the span of 2 days, and my battery life is horrible on all 3, Myn, mik 4.5 and 4.4, i updated all my radios, and wiped everything using format_all zip. . . and nada cache and dalvik too. . . i check battery and Android system takes over 70 percent of battery! do u guys think it can be a rouge app? if so is there an app that monitor all apps my to check which ones use the most cpu?? thanks!

Downgrade your PRI and try Mik's ROMS.

thanks for the quick reply?
should i downgrade only PRI or NV too?

you should try process manager, it tells you which apps are running on real time and tells you how much cpu is being use, that should help you pinpoint if its an app. also ive noticed that every phone takes roms differently, because my wives phone had some isues that mine didnt in some roms and mine had some that hers didnt in some roms. i have noticed that that my battery life increased alot with setcpu and underclocking my evo to 245 when screen is off, also turn in settings moble network setting data always on, that will allow your data connection to stop when you are not using it for a while and come back on when you need it. also try turning mobile networks completely off and do a normal reboot, then turn them back on. ive noticed that with some roms when you first start your phone it immediately conects to 4g when it starts and when you turn it off, it still keeps trying to connect in the background, but when you turn mobile networks off and the reboot and then turn mobile networks on afer it reboots the problem is gone. hope this helps you with your battery life

sorry correcting a typo in the previous post, i meant turn mobile networks always on to off

No, you do not need or have to downgrade the NV. The current baseband and PRI causes wake locks, thus, a major reason for the quick battery drainage. Downgrading the PRI should eliminate the wake lock issue and improve your batter life.

Some people have said that they downgraded the PRI and didn't get the battery savings until they downgraded the NV. Just depends on your phone sometimes.
Here's a link to download different versions. Thank Calkulin for this, he is the man. http://forum.xda-developers.com/showthread.php?t=715485
I've used MikFroyo, Myn WarmTwoPointTwo, MIUI, CM6 and CM7, and by far I would say I've had the best battery life with CM7 and MIUI (CM7 just barely better.)
Try a different kernel if you want, I just Tiamat 3.3.1 for AOSP ROMs and Netarchy-toastmod 4.3.4 (both CFS HAVS no-SBC). I've had good results, stock battery lasts a day with moderate to heavy usage.

[Q] Battery drain and 3G connectivity loss

Hi all!
Since a few months ago, my Desire has been having two major issues:
- Huge battery drain in 2 to 5h time (unable to identify application responsible, powertutor reports android system or os - can't remember -, while built-in battery usage monitor reports either display or cell standby - the second appears especially when the phone is idle and supposedly sleeping). The few times I enabled airplane mode, I got double battery time, though it doesn't come close to former normal battery time.
- 3G connectivity loss, when going through no signal areas or when the phone is forced to switch between GPRS and 3G and vice-versa.
Regarding the second issue, I've already tried to enable GSM (auto-PRL) and the result is practically the same as having 3G enabled. Only factory resetting after enabling the former setting and choosing GPRS only, in Settings works in no signal downtime.
Nothing I've tried takes care of the battery draining issue, even hard-resets. I've already flashed different roms from Eclair to Gingerbread, from unrooted stock to root stock-based: no real change.
So after this rambling, my question what is more likely either some hardware malfunction or a software bug in the android system or in some application?
Anyway, I'll try to use systempanel or watchdog to try pinpointing the culprit.
Thank you.

Flash latest radio

Also worth thinking about the kernel, I had a similar thing to you, and it was because I flashed a different kernel to the one packaged with the rom.
I would also try a full wipe, ie cache, data, system etc. in recovery and installing something clean eg oxygen rom.
The suggestion above about the radio is definitely worth trying also I would check that your current ril is compatible with your radio version:
http://forum.xda-developers.com/showthread.php?t=902752

Hello! Sorry for not answering sooner.
I have been running the latest radio for at least one month, and it hasn't changed that much the issue.
Also, at some point, I did try another kernel, having seen that suggestion elsewhere in the forums. It also didn't change much.
Finally, I have also tried flashing and using the clean oxygen gingerbread rom. The battery time improved a bit, but didn't go back to normal.
Still, after seeing the results of systempanel monitoring, I will try flashing oxygen rom again because, perhaps with 2.3.4, whatever the issue is, it might have been fixed.

Try to calibrate your battery:
1.) Load phone till full when on
2.) Turn off and load to green led
3.) Turn completely on, turn off and load until green led appears
4.) Boot into recovery, wipe battery stats and now use phone as normal
No warranty for any damage.

Did it start when you flashed something new?

Hello!
That is possible. However, I have flashed and formated the phone many times since then and there has been no change.
Also, I have been monitoring the cpu usage through systempanel as suggested in some other threads, throughout the last weeks and in average, there's no installed application going further than 10% cpu usage consistently. When seeing the history of usage, at the top I have the system process, which has an average consumption of 0.2% over one week.
So, the phone seems to be working normally, but when using the currentwidget app to see the current drawn from the battety in each instant, at the best I get 50-70 mA, at the worst I get 700-800 mA. On average, 300-500 mA consistently.
I think something is draining the battery consistently much more than normal and also causing the baseband or the radio subsystem to crash, when switching from 2G to 3G or vice-versa.
I have done everything suggested in this thread, except for flashing a new clean oxygen rom and I've got no result.
What could be causing this: some hardware problem?
Thank you for your patience.

Maybe try the battery in someone else's desire, that you know functions ok, and their battery in yours? Perhaps the battery is dying?

Since I haven't been able to find anyone with an HTC Desire and I can't be certain if the problem is with the battery itself, I'll just send my Desire for repair to HTC.
Hopefully, they'll find and solve whatever the problem is.
Thank you all, anyways.

Horrible Battery Life

hi guys
i have tried various methods and i am using a new battery on rcmix3d on leedroid's kernel.
BT,WIFI is off. Data is on 3g 24 hours.
My battery drains 1% every minute when data is on even though its not polling for any syncing or data.
my sync is set to once a day for emails and manual for the rest.
i have also done a battery calibration and still no joy.
any tips?

Download current widget, and set it to log your current drain while idling. Sense rom should be around 1ma-3ma idle.

thanks..
actually my its ard 1ma to 4ma idle.
this is when juicedefender disables the data.
but the moment data kicks in, its spikes to a max of 280ma and the battery starts draining. i can actually see it dropping per minute. the moment data is off. everything is as per normal.
does 3g really consume that much of batt?

No it doesn't use that much at all. Did u do a full wipe with install of rcmix?
Do you have any apps installed that may drain battery. Try using a task killer to close all apps and see how it goes.
Just to be sure have u tried turning off mobile data and checking battery with it off. The maybe new radio may help
Sent from my Desire HD using XDA Premium App

other than 2 camera apps,ebay,paypal, foursquare and facebook, i have nothing else.
and notifications has been turned off for all the above.
i tried task killers and they really didnt help much.
i did do a full wipe and battery does last way much longer with data off.
i'm also using the latest m2 radio and underclocked the cpu via setcpu
an advise on which radio would be better?

Go with the radio suggested in the thread for your rom. If none suggested just grab something different to what your using and try it out.
You shouldn't need to UV the CPU. Mine runs at 1.4 no problem. Let me know how I get on.

Just realised your using a new battery too. The have u tried your old one just incase its a battery problem.
Sent from my Desire HD using XDA Premium App

yeah..the old battery was replaced with a new one by HTC service centres.
i was just reading the radio thread and decided to flash the corresponding RIL for my radio.
i'll try that for a day and see how that works out.
thank you so much for your help and i'll keep you posted

you problem is radio related.
flash the suggested radio of your rom.
had the same problem a few days back. 150-250mA idle, when i deactivated my data connection, it went down zo 1-4mA again.

I had the same problem, 4 hours of sleep would sometimes see 20% disappear. New radio and kernel did the trick.

Keep in mind, cell reception is also a varible factors in regards to battery life, but with the situation as precribed it is more than likely to be radio/RIL selection. Also remember that the newest versions of radio and RIL may not always offer the best reception and/or battery efficiency, ideally use the one as recommended by the ROM/Kernel. You may also consider searching the forum for see the recommended versions of radio and RIL to match.
During new flashes of the ROM, under CWM, you can also delete battery stats which should allow a more accurate report of the battery.
Hope it helps.

thanks for all the info guys
i guess its probably a radio/ril issue.
i'm testing out various ones right now.
anyone using rcmix3d 2.0 got a recommendation for radio/ril combo?

The new telus radio, it's great.

Download Android System Info from the Market. Look out for anything that is using an excessive amount of processing power.
After that, you can see if it is the radio.

hi there
i will try the telus radio soon after trying out the one recommended by the rom dev.
what am i supposed to be looking for in android system info?
batt stats bring me to the default batt stats that is in the android system

[Q] 28-35 mA Drain Issue

I'm at my wit's end here. There's no indicated partial wakelock by much of anything, but somehow my phone has a drain of around 30 mA when idle. It seems like this is off by something like a factor of 10 from what it should be.
Does anyone have a conclusive fix to this mysterious battery drain?

I'm on ARHD 6.1.2 w/ Revolution HD theme, with no applications that visibly are hogging CPU or partial wake locks, currently just wiped the entire phone and in the process of calibrating the battery, but for some reason it seems to be draining way too fast.
I'm not sure whether this is going to become an issue again, but I've always run into the problem every so often and a solution would be very much appreciated.

Are you using the recommended radio for that ROM? Radios make a big difference to battery life.

I assume you didn't do anything dodgy like restoring system data via Titanium Backup after you flashed your current ROM...
Also, you checked the MD5 of the ROM zip before flashing?

Is the drain constantly ~30mA when idle? does it ever reach the normal ~5mA it should when idle?
Check the drain in Airplane Mode to see if it's a Radio issue.

Flashed proper RIL for the radio I run, airplane mode is a steady 1 mA.
This has happened before, I'm not sure if it's the result of uncalibrated battery or just a bad ROM.
Currently calibrating on ARHD 6.1.2, seems mostly smooth sailing with <10 mA drain idle.
I run an Inspire so I use the latest GB radio/RIL released for the Inspire.

[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.

i am thinking about changing my radio... doing research n stuff... lets see what happens.
as it would solve the signal issue and battery all together.

bro if ics solves the problem of battery drain due to low signal then y not... i will surely try...
i dont get a single percent drain on airplane mode the problem is surely network sucking it down... yesterday it went 100% to 48% in 8 hours in deep sleep n no wakelocks[betterbatterystats] :crying:

guys it is to update you i have just updated the latest radio for desire hd from
here: http://www.icsforums.com/forum/showthread/26951
from version:12.54.60.25P_26.09.04.11_M2
to:12.69.60.29_26.17.14.11_M
i will use it for a while and will let u know its results.
thank you for all your support.

well the radio update did improve the battry a little
now it drains 40% instead of 50% but still its not enough.
can somebody tell me how to control the modem to not search for signals that rapaidly.

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!

as i mentioned bro the problem is purely regarding the network sucking down the battery my bluetooth gps wfi everything is turned off... i use 2g gsm only... if u put ur cell in airplane mode the battery doesnt goes down by a single percent. its gsm standyby sucking the battery.
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
downloaded this zip and replaced the radio.img within the zip from above link.

put the file on sd card root
booted in bootloader
that did the job.

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.
