Battery

I am going away this weekend but I won't be able to charge my phone. What are your tips to help make the battery last (I'm on cm7 if it helps)
Sent from my HTC Wildfire using XDA App

Underclock it.
Disable wifi/3g/bluetooth
Lower screen brightness.
Disable tactile feedback/vibrations.

and disable animations and delete widgets you will not use. But indeed, I could get 4+ days out of my wildfire (stock rom) by just not using internet

Any cm7 specific tweeks and what should I underclock to

Dunno if this'll help but disable JIT

Looks like you have an app in the background that causes your problems and dont let your phone to deep sleep

i figured it was something along that line...since deep sleep takes up so little. but i thought the screen is the biggest waster, any app that is simply in the background shoudlnt deplete my battery so fast.... i have to charge 3 times a day...
BUT HOW DO I FIX THIS..

Yes, but the screen cant eat your whole battery in 2h ... i have ARHD 6.1.0 and stock kernel and my screen time is about (minimal) 4h with autobrightness

I am not sure what apps and mods you are running, but what i would do is:
-install android wall from HERE to block some useless apps to access the internet (this app has a widget too so you can enable and disable the firewall whenever you want)
-use more the task manager to track what apps are running
-follow this instructions (the one you think could help)
-and disable some unneeded apps here
edit: almost forget, dont use any task killer, they are useless and causing more battery drain ... ill quote one of the best kernel devloper we have on the HOX so far, faux123: "Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close)."

[q] big battery problem please help!!!!

No matter which ROM i choose wether its 2.3 based or 4.0 based, Calks or Phantom. Even CM9, Team Dirt. I always get crap battery life. ANDROID OS and ANDROID SYSTEM hog the battery!!! Why is this. The only thing that has not changed will i have been flashing all these roms is the Modem. I am currrently running FF18 Modem. Could this be the culprit? Please help guys!

The android os usage in ICS is normal. What do you consider bad battery life?
So many things affect battery life. Low signal will wipe out a battery in no time, synching multiple accounts (email, facebook is notoriously bad...) and software you may have installed. How is the battery drain when the phone is sleeping? Since there really isn't much we can do about battery while you're actually using the phone, the next step is to improve on sleep efficiency and this will help the battery life overall.
Try installing BetterBatteryStats. There is a thread here on XDA you can search for and download and install this app. The best way to use it is to let the phone sleep on battery without using it for a minimum of 2-3 hours, overnight is best. Then view the kernel and partial wakelocks to see if something isn't allowing the phone to sleep properly.

battery battery life?
Couldn't you also use multiple profiles in an OC app to undervolt and underclock the phone when it sleeps? (screen off profile set to 800MHz and screen on 1200MHz) Just a suggestion, hope this helps.
I have to charge my phone twice a day because I am on it all the time. My ave battery life 11hr 47min. Running Badass Battery Monitor.

Turn off auto sync for your Google account on your phone and manually sync it from time to time. Before I did this android was at the top of the list in the battery. Now screen time dominates everything else in usage.

Yes I did this too, it helps a lot

Yes, synching too often is a killer.
Don't forget about the phone radio too: wifi/bluetooth/gps/data/4G all can have a negative impact if left running.
Someone recently posted that at his workplace, he had zero signal and he could barely make it through the day. He discovered turning data off entirely in that scenario saved battery in a huge way.

Bad battery to me is loosing 60% over night. That's running CM9, android is and system were the dominant battery hogs when that happened. Please help. I've downloaded betterbatterystats.apk but I don't know how to use it. Please help.

I guess you should try downloading any battery calibration app from the market and also try battery control.... I hope it would help you..... Or the usual juice defender :thumbup:

I recommend underclock your cpu to 1 ghz

I've been under clocked @ 1.0

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?

i agree on this post

Battery life android 4.2

I've tried a few android 4.2 roms, and the battery drains too fast? Any advice on how to deal with it? It was great on 4.1
Attachment is my capture of betterbatterstats, can someone tell me if the stats is somehow abnormal as well as how to enhance? I'm using Rom SentinelROM v4.60-CM10.1
thanks

Use xmkernel , underclock it , undervolt it , switch off location services and reduce brightness to min
