Help, my phone is dying even though the battery still reads 9 percent left. I am using darkstones froyo build v3 and 2.12 radio. Is there some way to reset the battery to make it go down to 0 percent ?
Sent from my HTC HD2 using XDA App
turn off phone. charge up to 100% and then start windows. make sure the battery reads 100% after charging (with phone off), if it reads 100% then boot android. and let it fall to around 50% (take note of exact %) turn off, boot into windows and check if % is same on windows as it is in android. if so, w00t theres your problem solved. if not, well. thats it. nothing more to do.
also. this should have been posted in darkstones thread..... NOT POSTING A NEW THREAD IN DEVELOPMENT.
and if your finger was itching that badly to make a new thread. do it in the GENERAL OR Q&A FORUM!!! NOT DEVELOPMENT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Same problem. Are you using Hastarin's v7.7 kernel?
I wasn't getting answers on darkstones thread and I wasn't itching for posting a thread. I was itching for an answer.
Thank you for the tip, but I've already done that. Ill check again.
And no, I'm not using that kernal. Are you?

my phone just died it was reading 7% when it died. using the Nexus one build 1.5 and stock kernel 10.27.
Charge to 100% (as in: turn it off and make sure it reaaally is fully charged), then remove battery stats using a root explorer (Google for where exactly this file is stored), then let your battery run out completely. Afterwards, problem should be fixed.
The hastarin kernel didn't help. Same thing happened.
And do I let the battery run out in android or winmo after deleting the battery stats file? I removed it before with terminal emulator but didn't let the battery run dead in winmo. It died at 9 in android again.

Battery is draining at least, and I say at least 20 percent per hour, and to top it off, i can only get full charge if phone is turned off. Other wise it charges to 83 percent. Any ideas?

No info? no kernal version? no rom info?
We can make random suggestions
I use shubcraft 1.5 with michy's r11 kernal with setcpu underclocked to about 800mhz.
I use current widget to gauge what batt life wll be like.
Using the most recent hyper droid. Not sure about kernel, but I downloaded the most recent off some website last week
Sent from my HTC HD2 using XDA App
20% per hour is really weird. do you have setcpu installed? with it i could reduce drain from about 5-6% to 1.6% per hour!
as far as i know in no android build you can charge to 100%. that means not in android... you should shutdown your phone and charge it then. after that start android and it SHOULD show 100%. mine charges till 96% in android - in winmo and shutdown it does to 100%!

So I have seen a couple users asking about creating a new thread for battery life on CM7 only, so here it is. I am getting ok battery life, but nothing near where it should be.
Here is where you can suggest, try, try again, and submit findings pertaining to the battery life. So let's get this started!!

I've found that turning off the radio saves battery life so I def. think that the radio is the problem for it
Thanks for starting this. It should be interesting to see where this thread goes.....
You mean flight mode? I don't think that is a viable solution, well at least if you need to use the phone. I can't even get xda super power installed for some reason

I get better battery life with KB5 too.
I can confirm that data use is probably part of the issue. I live in the sticks, there is no 3G at my house. My battery life is actually descent, no where near what I had with Froyo, but it doesn't seem to be anywhere near as bad as other people are claiming.
turn off background data when you don't need it, don't use auto brightness.

Personally, I've just read from some ROM thread here, that you need to calibrate your battery if you flash custom ROMS. So far, it has worked out quite nicely.

Yes, also doing that. I recommend to go to the Android Market and search for Battery Calibration by NeMa. It's a great, free application as well to make sure that your battery is calibrated on top of the instruction from the quote.
Using spare parts app change wifi sleep policy to never. Known bug in gingerbread. New wifi drivers were just released for stock builds but I don't know if theyll work on cm7 or if they will be implemented.

Ya battery calibration app works quite well, that is something I haven't done yet with this ROM 0_o
I was having terrible, absolutely terrible battery life with CM7 and I decided to do some investigating. On my initial installation I used Titanium backup and Google Backup to restore settings and applications. I could not manage 4-6 hours on a single charge, with calibration.
I decided to do a fresh CM7 install to test things out. I simply booted into recovery and wiped data, cache, and system. I reinstalled the initial package provided on the CM forums and let CM7 boot. After letting the new installation settle down for 10 minutes, I rebooted into recovery, flashed gapps, and then the newest nightly. Again, I let it boot and sit for 10 minutes before performing anything. After settling down, I charged up to 100%, rebooted into recovery again, and wiped battery stats.
I should note that through this I declined google's offer to use backup services and declines google's offer to restore any old backups. I also decided to not restore any apps through titanium backup.
With my screen brightness set to 100%, wifi enabled, bluetooth enabled, and using the phone at amoderate to heavy amount, I have gone 12 hours and am at 5%. I am certain that after the battery stats can calibrate fully and run through a few more charges I will easily hit 15 hours on moderate to heavy usage.

if you have rom manager pro the nightlies are available for download.
here's a few tips for you guys:
1. turn off 3G, stick to GSM only. Found in settings > wifi and network > mobile network> gsm only
2. use some black themes, anything than the normal grey and stuff should help
3. If you have data, use that instead of wifi, from what I see wifi eats more battery
4. if you're using wifi, go into wifi settings > *menu button* > advanced wifi settings > wifi sleep policy to: when screen turns off or never when plugged in.
hope that helps
This thread has been very helpful. Thanks
So... I was wondering... WHY DO WE GOT THAT PROBLEMS !?
If we take the NEXUS S Rom and convert it for our PHONES (GT540), where is the TRICK ? Why do we get that problems with the battery and te NEXUS S users not ?!
NEXUS S got the same battery like GT540 and after the GSMarena compare, the GT540 takes it much better then the NEXUS S !
CAN someone explain it maybe ?! Cause I really dont understand
Its the rom itself not the battery.

Im sry for that topic and for that question, but Im gonna sell my phone cause of the freakin ****ty battery lifes on every better ROM
Well the rom has a file with the battery calculator. And this isnt calibrated right for all roms.
Also most roms are still under active development so dont get your hopes up about good battery life etc etc

I think battery problem have something with kernel, on 2.1 i use 4 diferent kernel (orginal lg, 666 infernal, quarx, pcfighter) and every kernel have diferent battery life, diferente dischargin steps. So... no orginal kernel no good battery life.

THX for you answer !
I have a Nexus S. The battery lasts 1 day If I use .It is not overclocked (yet) . The battery is same on gt540 it lasts 1 day if I use it.See the attached screenshots from my Nexus S.
What I usually do is that after the battery is charged to 100%, I reboot the phone in recovery and keep it plugged in and charge for anther 15 mins. That seems to give me an additional 1 hour as my phone stays at 100% for at-least an hour before falling back to 99%.
I have had my phone off charge for 5 hours and its sitting on 95%.

Battery depends on few things.
1. Kernel
2. Rom itself
3. It will drain faster with data on.
4. Some crapy apps kill your battery.
Choose kernel and rom wisely. Turn off your data if you don't need it. Uninstall unnecessary apps

FOR all those WHO GOT the same problem like me...
I fingered out how my battery is holding for 4 days now...
When you plugin your phone into charge mode... just dont let it to go into "SCREEN OFF"... make your Screen OFF to 30minutes and just hit the screen every 25 mins... or just install an app which doesent allow your phone to autoScreenOff it
After this lil trick... it just works for me now... I hit 113Hours with this trick on Muraiks M6 Version !!!!!!!!!

You don't need an app You need to go to development settings and click never sleep on USB. Thats what I do
I was told to post here..
I bin using litening rom v1.5 for like 2 weeks..everything was running fine untill 3-4 days ago my battery would drain in like 3 hours from 100%. After it drained i would try and charge it..it keeps freezing on the battery screen and changing all diff colours lile blue red green. When v2.0 come out i flashed it via odin. I done all the basics like wipe data/cache ect. After it flashed i recalibrated battery..but last night it done the same thing. Any help would be appreciated thanks
Btw when i go to battery usage 'Android OS' says 97%. I dont have any other apps running in the background nor have i changed any settings. Its all stock settings. I dont run any overclocking apps. Only root apps i have are cachemate, titanium and CWM

recalibrated battery not after flashing a rom,
but after the battery completely recharges.
I'm sure its battery calibration problem,
Do this
Let the battery die completely (let the phone turn off by itself)
Then connect charger and let it charge till you get charge full notification,
Then recalibrated your battery.
Btw next time if you have problem with some rom, make a post in that roms thread.
Dont start a new thread Especially in the wrong section.
Can I ask you who told you to post here?
Thanks very much. Erm i forgot who told me to..i think they meant in the offical litening rom thread i must of missed read sorry im new to this. One more quick question, should i use the battery calibation app i downloaded off the market or boot into cwm and wipe battery stats?
Sorry for the inconvinience

Whenever I leave my phone charged overnight, I wake up to around 70% charged. It's as though once it reaches 100%, it stops "charging" and it starts using the battery's energy, rather than the AC. Any help?

What kernel/rom are you running. The only suspect is that your kernel does not have "trickle charge" in the new kgb kernel you have to enable this with the app.

Is there any Custom ROM in particular that you would recommend?
go here http://forum.xda-developers.com/showthread.php?t=1238070 and follow step 2, then go to http://forum.xda-developers.com/showthread.php?t=1459905 readthrough the first part on TW kernels, choose one of the 3 custom kernels (not the stock one), best advice is to read the op of each one and find one you think will work for you. they are all three well written kernels. one is already oc'd to 1200, which means no need for voltage control if you plan to oc your phone. most phones are stable at 1200 but thats just from doing alot of messing around and odining. the second post is the instructions for flashing the kernel. the first post just explains all of them to the best i could w/o kanging any information from the op. i just ran what i knew off memory. links to each kernel's op are at the bottom of post 1. i did links to the op's instead of posting dropbox files due to the fact that I want people to make sure they know what features each kernel has before they download it.

They are essentially the same thing. Battery Calibration is wiping the battery stats and running the phone dead than fully recharging.
I have been having a very similar issue. A buddy of mine (captivate) and I found that the phone wont charge past 98% on CyanogenMod with the Glitch kernel. I set the phone to not lock and keep the screen on while charging and the problem went away. The phone also would not stay on A/C power after reaching 98%. This issue was fixed too.
I think its an inherent problem with the batteries on the phones, since the issue occurs on many different roms/kernels/phones.
whether it's caused by the phone, ROM, or kennel, battery calibrator is a simple app that is at least worth a try in my opinion
