Improved my battery life after leaked OTA

I thought I was losing my mind, after installing the OTA, I modified my qwerty.kl file to wake up the phone from the optical button. I noticed that my battery life was lousy, and originally thought it was because the OTA was buggy.
I restored the stock qwerty file, and no more wake-up from the optical button. My battery life improved drastically.
I heard that this change could prevent the phone from sleeping, thus the crappy battery life. Is this true?
Hope this tip helps.

Re
Anybody else have a faster draining battery because of the optical wake fix?

Could be just because you are accidentally hitting the optical trackball while its in your pocket or somewhere else? I use it on PMF's 2.2 ROM and haven't noticed any additional battery drain.

I think its because we are all forgetting to clear battery stats. It is even required on my rom, jdfroyo

What exactly does clearing the battery stats do? Do you think it would help me? If my phone completely dies or gets down to the low battery warning, the phone doesn't want to charge at all.
It says it is charging but the battery icon isn't animating and the charging led blinks repeatedly instead of staying lit up. Even if I shut the phone off the led still blinks while it's plugged in the charger.
I have to do several reboots and battery pulls to finally get the phone to start charging.
Didn't have any trouble until I applied the OTA and flashed a 2.2 rom.

this is very intriguing. i'll check my battery against my fiance's when she gets home and report. i did the optical_wake script on mine and not hers. i'm pretty sure she had 40% when going to bed last night and I was changing out my battery for my backup. i chalked it up to streaming the race for 30 minutes while we were out shopping, but I think the optical_wake script might make more sense.
PS. both have 1500mah HTC battery ordered from bidallies on ebay for $15 =).

No difference. Our batteries were within 5%. I guess flash vids are pretty taxing on our batteries.

Interesting....maybe I'm just losing my mind and imagining things?
Thanks for your update - after I install the new OTA leak right now, I'll see how my battery life is with the optical wake fix.

Check out jdfroyo when i update it. I tweaked it so you get 15-35 min more battery and no overheating!

Myself as well as many others would be interested to know what this tweak is to achieve better battery life.
Some of us out there actually like Sense - from what I understand, your ROM is de-sensitized?
Any chance you'll fill us in as far as what tweaks you've made? I'm sure I'm not the only one that would thank you.

Droid X battery fail

So I bought the official Motorola extended battery. I've followed ever freaking guide there is to resetting the battery and all. I still have issues with my battery, multiple roms, wipes, resets haven't helped. I unplug my charger at 7am, by noon I have 10% or less left. It stays low till it turns off sometime the next day.
What am I missing.....

That's very odd.
I know that you stated you had already tried a battery wipe, but just to be careful:
Charge to 100%
Let it run completely dead
Charge to 100% without turning the phone on
Wipe Battery Stats
Also, there's more information I need to post here, and what rom are you using?
Sent from my DROIDX using XDA App

I'm running MUI, latest build. I don't think it will charge with the phone off will it? On this rom I mean.

the 2nd Init ROMs won't charge while off. You should try putting up with a stock ROM for a day while you troubleshoot the battery. If you can correct the issue using the above method you should be gtg. Once it's fixed install MIUI on a full battery and do a battery wipe.

Ok so I flashed back to Libery .9. Charging from fully dead now while off.

Why not? It is nice to have always-signal available though

The miui rom drains the battery quite fast I have the extended life and I get about a day with miui. when I switch to cm7 I get about 3 days its the rom itself unfortunately

Not sure what it was, I sbf'd, updated to the latest greatest and it still didn't work. Gave up on it, bought a Bionic when it came out

battery?

im running the stable cm7 release and my battery life is terrible. i followed the guide on the forums here on fixing your battery life, charging to 100% pull battery put back in instal battery fix etc and overnight (short 5 hour night btw) i lost over 25% of my battery life, doing nothing ! wifi off data was on but i only recieved one or two emails all night. is this normal for cm7?
i read about how people are getting 20+ hours battery life while using their phone, if i leave my charger at home and go to work my phone is DEAD halfway through and all i use it for is the occasional phone call mabye 5-10 texts throughout the day and an email or two... how can i fix this?

I read somewhere that if you flash another ROM with battery not fully charged, it messes up calibration and you have to calibrate again. I am still with stock Blur just because I read so many issues with so many people about batteries
I hope you can get it figured out.

anybody?
is anybody else having battery life issues with cm7? if not did you do something to fix it? i have no idea what to do, the phone pretty much has to be tethered to a charger or it gets drained ridiculously fast. If i hang out with a few friends and use my phone during it i literally have to stop using it after around an hour or so because the battery's about to die.
Is there a certain rom with exceptional battery life that i can try to see if mabye its a hardware related issue? i seem to remember having horrible battery life for the day? or so that i was running stock ATT gingerbread.

I use Aura 1.2.2.2 (debloat) and get average battery life. Comparable to what I got before I installed third party ROM. If you want to try that one and see if its just CM then give it a go.
I had a battery problem after flashing to CM with a previous phone (OG Droid) but it was because I flashed while I had the phone plugged into the charger. It took a while to get it back to normal.
I doubt its CM. I dont know if its something draining your battery in the background or if its a result of weird calibration due to the flash.

my battery life has never been hte greatest but recently i got it working really well
I use the latest weekly build of CM7 and here is what i did
upon fresh install:
wipe battery stats
THEN:
kill battery
charge as far as it will go
clear battery stats (use battery calibration app)
take out battery
wait to reboot(missing battery)
put it back in
let it charge for 2hrs
reboot and unplug
kill the battery
charge to 100% while off (no interuptions)
Enjoy!
i have found that the more cycles my battery goes through 100-0-100
the better it gets
these steps almost tripled my battery life (along with Weekly 3)

there is a bug some people report with CM7 about the suspend process. (i have it, you can search "suspend" in the CM7 thread and see others are as well) load up the app betterbatterystats (there is a thread on xda that has the apk) and see if you have that bug.

I'm on nightly 20 having good battery life

I'm a victim of the suspend process bug
had to flash something else, using ALIEN for now and battery is pretty good
Sent from my MB860 using XDA App

i installed betterybatterystats as you guys recommended and im not entirely sure how to read it but the suspend process shows at the top of the list so i assume thats the process which is eating up my battery? Is there a fix for this? i do like cm7 but if its the rom which is causing my battery life issues ill have to wave goodbye. Does this suspend process but happen on the weekly / nightly builds as well?

I was having horrible battery life as well. I froze some apps that I downloaded from the market and that helped a little bit but what gave me 20+ hours of battery life is the new UK orange Radio that has recently been released. I wanted to flash it since I am using an Orange UK phone and see if it improves my wifi connection, etc....
Reddy flashing a radio appropriate to your device and see if it helps.

I had it on stable, and am on weekly 3 right now. I'm probably going to switch back to a blur rom soon..
Sent from my MB860 using XDA App

My battery blows with CM7. My phone has the suspend bug and nothing fixes it. I tried a fastboot wipe and clean install of the latest stable as well as nightly #20. I've tried several kernels, I'm currently running a screen off profile of 216-216 on the 1.0ghz kernel and I'm undervolted to the max just to make it thru the day.
I'm getting the nexus prime or the iPhone 5 next... which ever is released first.

[Q] battery charge misread

k so ive read through other posts and tried to fix this myself but nothing ive read has worked...
my battery was fine up until i installed the last miui 2.4.20 rom, then i started noticing that my phone is dying even though its still showing a certain amount of battery % still there. my recovery was showing a different percentage than my rom...i turned off the phone, charged it until the light was green, went into recovery, wiped everything including battery stats and installed RunnyMede Xtreme v2.1.3 w/ unity v10 kernal...still getting the same problem...ex. itll shut off at 80%, then ill check in recovery and it shows like 35%....what could be the problem?

You need a new battery your battery doesn't hold the charge anymore even though it shows it does check if your battery is getting swollen from the middle.

I had the same problem as well... I thought it was the same reboot problems everyone was experiencing in ics.. But yeah I just noticed that the battery is very swollen in the middle, holding tight, until the replacement comes..

I know I'm late to the party, but I have the same issue.. I replaced my battery and I'm still getting the same issue.

Phone getting power off with low battery dialog

Hi all, I am facing a strange problem, my phone is switching off automatically indicating low battery. However when I plug in charger battery indicator gives battery more than 50% sometimes close to 75%. I've tried a lot of ROM's mostly based on great work by Marcellusbe CM7.2 Alpha 8.3. Following are the list of ROM's I've tried and faced the same issue
GB:
AOSP GINGERBREAD STYLE ROM
CyanogenMod 7.2.0-RC3
Kyrillos' ROM 10.5
Currently Using : Pranjal's ROM
KISADWORX ROM v7.2.1
ICS:
ICS AOSP/CM9 (Alpha)
AOKP/CM9
All ROM's are fast and good, fits my requirement. But this battery off issue is there in all for me.
But battery indicator while charging in power off mode is always always showing battery level higher than 50%.
Help me out here. I need battery backup that can at least work for 1 full day.
Help me. Something is definitely wrong.
P.S. Also tried this with new battery. So no battery issue.

Thanks for the help. Not exactly what I am looking for. Everything isn't always simple as it looks to.
I am posting this after trying all possibilities in past 2-3 weeks.

Same happening with me also. Specially when I am taking pictures or videos.. taking into account the battery is quite old .. but calling time is still moderate.. but gallery/camera are consuming enormous charge,,

I've also had this issue for quite some time with different ROMs. Right now I'm using Kyrillos 9.6 OC for daily use and I don't have that battery indicator jumps anymore. Maybe you can try that ROM to check if it's a software or hardware problem.
