Hi guys,
Two weeks ago I started to notice my battery drains pretty fast since I installed topsmarts rom. Yesterday I flashed Neutrino 2.91 with Faux's 1.0 GHz enhanced kernel. I wipe data, cache partition and dalvik cache. The weird thing is the long battery life in idle, I unplugged the phone from the AC and in two hours it didn't drop even 1%. But just surfing the web with wifi on and only 2G, 1% last only ~5 minutes, which is very low compared with the stock firmware. The battery dropped from 99% to 94% in only ~15 minutes
I don't know if it is a kernel related issue or my battery is screwed.
Sorry for my ****ty English.
Options for fix: let your battery die and do a cycle
Try different kernel
Auto-brightness seems to be quite the battery killer on my matrix so maybe turn that off
Or try cm7 the battery life is about a full day for me

My battery has horrible life. I'm rooted running evil fascination and have done all the things that typically help with battery life such as disabling gps and wifi, and lowering brightness. In fact my brightness is currently as low as it gets and my battery use shows my display as 99% of my current usage. Even though I just took my phone off the charger 15 minutes ago and it's already at 85%. I know my screen can't possibly have taken that much battery so fast. It also takes about 4 hours to charge from zero to 100 because it's draining so fast. Can anyone give me some advice? I downloaded an app that shows my current mah or whatever but I don't know what that means. I notice when it's at 270mah my battery drains fast which is most of the time but a few times it has been at 2 mah and it doesn't drain fast then.
sounds like a rogue app keeping your phone/screen running when off.. I had the same problem a while ago, 96% screen usage and taking 6 hours to charge then draining to zero in an hour and a half.. unfortunately the only thing that fixed it for me was a complete data/cache wipe and reflash of the rom, I think I was on superclean 2.9.2 at the time.. could be the battery being wonky also, you might wanna look into the battery calibration app on the market or wiping batt stats in CWR

Hello last time when i was running Nessy#Fenice rom, my battery life was great, it could last for 4+ days without switching off my phone.
then one day i flashed another rom and wipe battery stats and the battery was no so great so i flashed back.
HOWEVER, i realised that the battery of the Nessy rom became horrible as well and was like dropping 2% every 30 mins! can someone help?
And also i would like to know which rom has the longest battery life? i only use 2g and occasionally 3g and i use my phone for texting and sometime go on wifi thats it thanks

Did you wipe the cache and the dalvik cache? After a rom flash, you should wipe the battery. Plug in your charger over night, next day you must have 100%, else you unplug for a second and charge again. The battery is full! Let the charger pluged in and reboot into recovery. Wipe the battery stats reboot and disconnected the charger. Now use your phone normally, run down to 5% and reload fully.
That's it.

If the ROM you are using is 2.3, then you can expect lower battery then on 2.2 while using 3G.
Install battery calibrator from market, charge to 100%, wipe battery stats and then use as normal. This should help a bit.
First, I apologize for my bad English.
I very doubt with my battery life. e.g. Today, I had been using my phone about 9hrs before battery dropped to 1% and after a few minutes it grew up to 2% and after a few minutes it dropped to 1% and grew up to 2% again
e.g.2. I turned off my phone when it has about 50% battery and after I turned on the phone, my battery directly dropped to 13% and after a few minutes it grew up to 25% WITHOUT charging.
I tried to wipe battery stats in CWM recovery mode, delete batterystats.bin, pull of the battery for 2-3 minutes, use battery calibration app, change the ROM or kernel or modem and it still no change
I am using Criskelo Rom v34, Speedmod k18 kernel and XXKL1 modem, edge on, sync off
Yup, seen that as well.
Just quit messing with all those battery related things, charge it to 100% a few times and use it up a few times without flashing roms kernels and wiping stats etc.
It should be normal after that. Give it a week or 5-10 cycles or so.
Thanks, I will try it and come back to review : )
i also had this problem once. i just kept using my phone as normal and the problem fixed itself
Just took the update and battery life dropped significantly. I was running stock rom, rooted, and kernel with CWM. I could use the phone quite a lot and it would last all day and still have 25%-30% left after being off the charger for 17 hours. I flashed the stock kernel and performed the update yesterday. I charged the phone all night. I was off work today so I didn't use the phone at all. After 15.5 hours, the low battery notification sounded. The battery meter showed I only had 11% remaining. The main culprit was the "Android OS" at 77%. Display, which is normally the main power drain, was only 6%. This shows how little the phone was used.
I believe its Entropy who has a thread that has really helped me. Could be a rouge app. Do you have better battery stats?

I have severe drain its been like this since I got it.
100% to 70% after light web usage on lowest brightness. In only 3 hours about 1 hour screen on tops.
Restart phone and its instantly on 25% restart again and its on 13%
This is with stock cm10.1 kernel and underclocked and uv dorimax kernel.
Every time it always happens.
Tried wiping battery stats and resetting fuel gage to no avail.
Even trickle charge didn't help.
Any tips on gonna replace the battery with an extended one but if this is happening there's no point.
My atrix 4g had tons more life compared.
