[Q] How to increase the battery life?

Hello Mates,
I am using Wildpuzzle ROM v0.8, which is having many problems in its stage.
The camera fails to operate sometimes. But I do managed to make it working using an external application.
The major issue remains of the BATTERY.
Its been a disaster for me to use it when EDGE 'on'. When the downloading is taking place, this phone starts draining the battery within 30sec for each percent. Presently i get the battery backup of around 120mins max on data usage.
One more issue lies in, the battery wont get charged beyond 71%. I need to reboot so that it shows somewhere more than 90%.
I have tried to reflash the v0.8 rom but facing similar problem again.
Will Radio update be a better option?
Can you recommend any better Sense Enabled Froyo?
Is this the bug in the ROM itself?
Help me, with your suggestions.
Thank You.

Recalibrate your battery. Just perform a search on XDA, there are many guides. It cant be a bug with WildPuzzle because I have personally tested it extensively, and this issue didnt exist.
Only after a fresh flash of a ROM, I get very bad battery life, but this is normal in all ROms I have tried. After 1-2 charge - discharge cycles, it fixes itself.
But because you are facing issues like it doesn't go beyond 71%, then jumps to 90% etc - Your battery definitely needs recalibration.

[Q] high battery drain on all roms!

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...

First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next

And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.

you might want to try a new radio too

same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????

I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(

Yeah this is no fun...

[Q] battery dead at 15% and green led at 90%

hello mates,
I have rooted my htc desire and installed redux 1.2 ROM(gingerbread) with a ManU kernel...When charging the LED changes to green precisely at 90% (which i dont have a major problem with as it will go all the way to 100% if kept on charge)..also the phone will die at 10-15% of battery...I have read other threads regarding this same problem and am wondering if its a calibration error or is the problem with gingerbread ROMs as someone pointed out...Otherwise the battery is fine...and gives me a decent 1-2 days of use with moderate usage...its jus the problem abt the 15% n going dead which is a lil troublesome as the fone has died on me many a time for that last important msg, call or IM...any help appreciated...cheers..

That's not really a problem. The green LED at 90% is normal for android (try to fix it with battery calibration, helps sometimes) and the shutdown at 10-15% is also normal. Just take the last one how it is, all batteries are different. Some phones shut down at 5%, others at 20%.

Please use the Q&A Forum for questions Thanks
Moving to Q&A

noticed this on ICS dev rom too but also had it on my old G1

You should try calibrating your battery for the 10-15% dying problem.
And as for the 90% LED changing to green, all AOSP ROMs do that, so no worries there

What worked for me was charging it while the phone is on, when the LED turns green, power it off and charge it again till it turns green.
Repeat this twice and then reboot.

This is to calibrate the battery. Some people find it useful to run a program called BatteryRepair, in my case I noticed a clear improvement on battery performance.
To avoid calibration problems with the battery, remember to unplug your phone when you flash a new rom!

Turning off at 15% of battery with Supernova 2.4 ROM
I am using Supernova Xtreme 2.4.0.0 ROM, and my phone turns off at 15% of battery. My battery is freshly calibrated and this problem did not occured with LeeDroid ROM and with the stock ROM neither. On the Droidzon page I have found some info in FAQ section, which says the following:
Question: Recently I let my battery go completely flat. When I switched my handset back on I was bombarded with forced close messages.
This has been reported once previously, but could not be reproduced under Sibere’s extensive testing under similiar conditions. For the same reason, unfortunately, we dont have a solution too. The OS is supposed to prevent a complete drain, and to shutdown at 15% and then 5%. The shutdown at 5% is supposed to be forced too. If it shutdowns, then this issue shouldnt occur. Data2SD depends on a normal shutdown to prevent data corruption. Once Data corruption has occured due to untidy shutdown, data is not unmounted cleanly, and then the issue can recur on every subsequent boot, which would require a complete reinstall.​
So it seems to be normal, connected to the ROM, and NOT connected to my battery (it is calibrated).
My question is (which goes to Droidzone firstly), what should I do, if I want to use this ROM, but I do not want it to turn off at 15% rather I want it to turn off my phone at 2%?

I'm afraid this is not similiar to the issue in the FAQ. Your issue is that phone shutsdown at a level earlier than expected. The Data corruption issue is because the phone did not shutdown at the expected level and went down to as far as zero level of the battery, which resulted therefore in an untidy shutdown with no sync or clean unmount of data2sd partition, and hence ext4 errors. The 15% shutdown level is a normal soft shutdown prompt (which was missing in case of the issue reported by the user). The shutdown at 2% is the normal forced shutdown by OS.
As I said previously, your issue seems to be due to a poorly calibrated or defective battery, and it would help to do a calibration as per guides on XDA. If this fails, have the battery checked. To reiterate, it's not a rom issue and not something like a bug in the rom.

Thanks. So normally the phone with Supernova ROM should turn off at 15%. After that I have to be able to turn it on again, and use it till it drains to 2%, and shuts down finally.
For me it just shuts down at 15% and then when I switch it on and it boots up, the battery level shows 0% and it shuts down immediately.

No, a normal rom would popup a warning at 15%, asking the user to shutdown. If he doesnt, it would continue, and then give additional warnings, and finally do a forced shutdown at 2%. If it shutsdown before that forcibly, it's something peculiar to your hardware.

Ooops, so Supernova ROM should behave exactly the same way as a stock ROM (or any other) does in terms of warnings and shutdows.
I might try to do something with battery calibration. Should I do it before or after flashing Supernova? Or it does not matter? If I flash a new ROM, does it delete battery logs or it stays as it was before flashing?

Correct. For all intents and purposes, Supernova is exactly like a Stock rom. Difference is only in where internal apps are stored.
The so called calibration is just a file at /data, which means it will be wiped when you do a wipe for rom install.

[Update] Problem solved. I flashed UOT battery MOD after first boot (not before). Now it works perfectly.
A flashed the ROM again, did the battery calibration several times, but the phone keeps turning off at 15%. I checked battery voltages at different levels of battery, and I experienced that at 16% it is 3635 mV, then it turns off below 15%. When I turn it on, battery level is 0% and the voltage is 3390 mV, and when it is charged up to 1% it is 3723 mV, which is higher than it was at 16%. What is wrong here? Actually I use UOT kitchen battery MOD, can this confuse the system somehow?

[Q] >:( phone shuts off every minute

okay so for the past weeks, i have been running the latest cyanogen rom nightly and i read about the script by puremotive that improves you battery life so i flashed it, everything was working wonderfully, noticed increased battery life but yesterday when i woke up my phone was off some how, so i turned it on and before i could even open an application it turns off. i mean like just turns off no bootloops whatsoever. When it turns off, if i have like full battery charge its drops down to 15%
so i was wondering is it my battery thats the problem or the phone?
and yes ive tried wiping everything and even flashed a different rom.

[Q] Battery Charging Issues.

Okay, I currently run CM10, about a week ago I flashed another developers version of CM10, and started having battery percentage reporting issues while charging, So I flashed back to the original ROM, formatted, cleaned battery stats and for some reason the battery will charge up to like 75-80% and stop reporting the correct percentage until I reboot the phone, even when back on the old ROM, I am using simonssimons34 ION kernel, which running it before with the old ROM, reported fine, so I don't think it has anything to do with the kernel.
I have almost always let this battery deplete to about 1-2% before a charge, and never over charged it, so I am a little annoyed that my battery stats are mis-reporting now until I reboot. Is there any fix for this? Or do I need to try another ROM or something? It only reports incorrectly while recharging, it depletes normally and never has issues with that.

This happens to me every day. Learn to live with it.

You can clear battery stats in recovery. There's also a few root apps that let you do this. (search for clear battery stats)
It'll take a while for it to rebuild accurate battery stats, but it sounds like at the moment any fresh stats is better than what you have now.

You can try calibrate with this app:

I've laready tried as both of you have suggested before, and it hasn't helped me yet, I did it two ways I did battery wipe in recovery, and through a 3rd party app, but the phone still wants to stop reporting the correct percentage until I reboot my phone.
And I even tried letting hte phone completely deplete after wiping battery stats, and it's still wonky ='(.

Ugh this is soooo annoying ffs, anyone ever had any luck on fixing this issue? I've tried:
Flashing two different ROM's, nothing
Charging, rebooting wiping stats, calibrating, draining to 0, rebooting, nothing
Using calibration apps
None of this has worked for me what so ever, the only thing that seems to work is rebooting after the phone has stopped reporting then it will show 99% then charged.
What I don't get is it will charge to 100% if the phones off, but if it's on the phone reports an incorrect percentage, wth?
I am about to try a full RUU reflash and see if that will fix it, but that's a last resort. HELP PLEASE!
