Battery - G2 and Desire Z Q&A, Help & Troubleshooting

Hi guys! When I got up this morNing my battery was at 100%, after 2 hours of screen off, it was at 55%. Any ideas what the hell is going on? I am using coredroid 1.2, set CPU I'd set to 1194/968, but screen off is set to 245/245. Any ideas? Thanks in advance 7

What's your battery usage overview saying?

Lol, don't even know where to find that on here... I've looked.

Also, I'd suggest uping your screen off profile one notch or you'll risk wake issues. You might also want to lower your minimum from 968, you're basically telling your device to never run slower than 968 and also check that the screen off profile has a higher priority than your main profile.

You probably have a bad app or system process keeping the phone awake.
I'd also recommend dropping your wake min down (even as low as 245). There's no need to force the processor to run at 968 no matter what. For the sleep setting, I'd try popping the max up to 368 (I think thats the next step up?) because you can have wake issues.

Ok thanks guys! I'll give these a try.

Phone getting stuck a low clock speeds

Every once in a while when I wake my phone up, the clock speed stays at what it gets set to when the screen is off. The profiles seem to not work at this point until I reboot. I'm running stable cyanogenmod. Is there any way to remedy this?

No. I did have that problem on my G1 but on this phone when it says it's running at 300 Mhz, it is. Apps open slower, linpack is low. It's definitely getting stuck somwhere.

I wkuld recomend auto detecting speeds to make sure its got the right info for your kernel. Then i would reboot the phone. Also try turning the widget off. If your still stuck uninstall setcpu and start frrom scratch. I would reflash my kernel at this point as well.

What apps were running?
Have you tried installing current widget to see what is exactly happening, or how much voltage is going through your phone, even though it's sleeping? (ie, screen off)
I have not tried yet
Sent from my HTC Desire using XDA Premium App
This happened to me a few times (with almost no apps running) on RC7. Updating to 2.01 seems to have fixed that for me.
If that doesn't help, try using a different kernel and/or a different radio version and see if that works for you (we're reduced to experimentation as nobody has ben able to determine what exactly causes this issue).
I'm well impressed with mine. I went to bed with it fully charged, used it a bit in bed, always play a game and check the forums. Not plugged in at all and woke up this morning and its still fully charged!!
Amazing, since I have yahoo messenger running always. Been using it a lot since I woke up and now on 96% but I know its mainly the screen that uses a lot.
Brilliant ROM tbh
See if this helps:

well it's not really going to save your battery life, it just lets you see when/how the battery is being used up
Yes we can atleast know what apps are eating our battery.

What ROM are you using now?
Are you using a Live Wallpaper?
Also mention something you've done after which the battery drained faster... (something done after rooting)...
I don't know and im not using a live wallpaper.but when I rooted the first app I installed was set CPU and its on highest frequency,also when u finished rooting I remember that I entered cmw and flashed an update.zip which came by itself.could you please give me a battery saving ram?

I think its definitely setCPU. When i installed it my cpu freqquencies would change every second between min and max frequency(no matter what governor i used). The result:excessive battery drain
I think its because stock kernel doesnt support overclocking(or even underclocking)...May be the devs could explain it
After i did a factory reset, battery is ok now for me. No battery drain when kept idle for a night:good:
P.S. Also before reset my HW decoding(in video playback) wasn't working(now its ok)....any1 experienced this too?
The problem isn't setcpu the problem is that he set it to 2ghz

I think it is the setCPU too, try to use no-frills, it is a tad better in my opinion, but stock kernel doesn't like non-stock settings that is for sure.
I upgraded to rc2.1 cz they told me that the battery drain will decrease, but its still the same

how often do you use your phone and what operations do you do with it... are you always on full brightness? is your gps always on? are you always on wifi or bluetooth? some things to consider that may take chunks of battery life..
Always on wifi

you need to reset the battery by the sounds of it, empty your battery tonight, run some games or put youtube on or something....there used to be an app on the market that would run gps\wifi\brightness all max etc and empty your battery for you....not sure if it's still there.....but when you do root you can clear battery stats which will make your life easier....but yea empty it, charge it while it's off and HOPFULLY everything will be fine for you also as a sidenote, i charge my phone with wifi on and internet radio playing in the night and charges to 100% fine
When should I clear the battery stats?
Sent from my HTC One V using xda premium
it's known to reset the "capacity" of battery, but personally i don't believe it.
Use program BetterBatteryStats and see what's keeping your mobile phone awake, and also install CPU Spy to see on what frequency is your phone mainly working.

Not true, those programs are used only for troubleshooting, and are mostly deleted afterwards.
They helped me countless of times, so why wouldn't he give a shot?

Extremely high current drain during screen on

For a long time now, I've been experiencing high current draw during screen on. Literally I could stare at the to of my screen and watch a percent drop off every few minutes. During standby my current draw is ~10 mA so I think I can rule out the possibility of wake locks causing this issue. CurrentWidget reports ~500 mA just doing regular activities such as adding events to the calender, using the calculator etc. Using Facebook the current draw reached a peak of 1000 mA!
I have attempted numerous ROMs and kernels with no luck, performed a wipe each time.
Is there any other options other than a full factory reset?
Currently using:
ARHD (latest version)
Franco kernel r12
-lowest screen brightness
-drain seems the same on airplane mode.

I would first switch to stock kernel from Franco. Is your ARHD 2.05 based? If so, kernels other than stock may need repacking. If nothing seems to work, a full wipe would be the last resort.

Cyanagenmod battery life.

Hi guys,
I've had a less than impressive battery life after I had Cyanagenmod installed on my hox. I know it's the norm for the screen to be the highest consider of the battery. However as you see in the screenshot it's the OS. Is there something I should do?
I can lose half my battery life consumed in an hour of moderate use.
Help would be appreciated, thanks

Well in general aosp Roms use more juice than sense roms.. have you tried those? Before you do that though, have you checked what drains your battery with an app? You can also use greenify to hibernate apps running in the background
Sent from my HTC One X using xda app-developers app
Thanks for your reply. I'll try greenify, what app do you recommend to check which apps use more juice?
Sent from my HTC One X using xda app-developers app
Well I'm not sure if I can give any recommendation, but I use Gsam battery monitor (Something along those lines..)
There are alot of apps on the play store that do the same so just get one that suits your needs
I would advise against any app that says to improve battery life.
They scan for apps then shut them down, if that process didn't finished their task the os starts them up again only to be closed.
They do more harm than good.
I would suggest using a custom kernel and underclock/undervolt.
Lower screen auto brightness amounts.
