I just root my phone last night and my battery is dying pretty fast without me even really using the phone.
Does anyone know if flashing a new kernel or any tips to conserve my battery?
Flashing a new kernel could help.

Always wipe battery stats in CWR Advanced>Wipe Battery Stats whenever you flash a new ROM. Also, you have to give it a couple of days to sort itself out. I've had ROMs lose 10%/hr in standby for the first day and they usually level out after a day or two. Especially CM7. Then try messing with kernels and whatnot. Just give every setup at least 2-3 days before passing judgement.

I assume you've verified that no rogue apps are causing battery drainage, correct?

Hello All,
I've got a Droid X with the handy and convenient one-click root method Z4root. However, my wife's Droid Charge is an entirely different story. So far I haven't rooted it because I'm hoping to use that as a last resort (I don't want to brick her phone).
She was having some trouble with battery life, so she bought a Samsung extended life battery. Instead of her phone dying within 4 hours of a full charge it could make it pretty much all day. But this week all of a sudden, even with that, she's back down to 6 hours, if that.
Early on when she got the phone I downloaded Advanced Task Killer for her and gave her some basic tips (low brightness, no mobile data, etc.), but I'm at a loss. I'm not sure if it's the GB update or what. I'm almost ready to root her phone and roll it back to Froyo because I think that's part of the problem, but I'm at a loss. Do you guys have any suggestions? Or is rooting, battery calibrating, and cleaning out bloatware my only option? I'd appreciate any help. Thanks Droid experts!!!
Don't use advanced task killer first of all. It will probably reduce battery life. GB update has made the battery better in all situations.
Whether or not to root is really up to you however if you do decide to root it is actually quite easy to root EP4D(the latest OTA update). Here is an easy to follow write up that I did:

Personally I rooted my phone and I have loved it. When I was using stock rom debloating did help some with my battery life. The biggest difference I found however when when I flashed eclipse and imnuts pbj EP4D kernel on to my phone. Eclipse is an awesome rom that is already debloated and has been tweaked to run super smooth. Imnuts pbj kernel has lots of great performance and power saving features(for example the ability to undervolt). Running stock I would get about 8 hours of moderate use from my standard battery(1600mah) and 4 hours of heavy use. Running Eclipse with imnuts kernel I get 18-20 hours moderate use and 8-10 hours heavy use.

calibrating the battery would probably help. id check to see whats running; gps, wifi, bt, etc. also it could be a rogue app that is sucking up all the juice. juice defender could help and if u have no use for location apps u can go into setting/location and turn off stand alone gps, google location, and vzw location. but def root the phone and put a custom kernel and rom on the phone, there will be a big difference.
I find that Facebook often runs rampant and needs to be told to stfu constantly. Also, a custom kernel with aggressive undervolting will help too.

I agree, and you'd think with all that money they're worth and throwing around that they could make an app that doesn't GARGLE TESTICLES

I am looking for a rom that handle me using my phone all day and not dying. I would love to find a rom that possibly allowed you to turn off the lte or whatever. As long as i dont have to charge my phone 3 times a day. Can anyone help me out?
many topics posted on this, the search feature is ur friend
My opinion
Seanscreams skyscreamsandwich rom has excellent battery life, I think if you try that with the new UCLA kernel you'll be very happy.
I have the stock Rogers ROM, rooted with CWM installed. I installed updated stock UCLA radio and kernel last week to get the benefits of latest kernel. Worked great but I've never been thrilled with battery life so Saturday I flashed Faux kernel v. 9m I think it was, on top of stock ROM and new updated stock radio.
Installed Set CPU to control new scalable speed kernel. I'm not easy to impress but it's absolutely unbelievable. Set to a conservative profile I've got blazing speed and 50% better battery life after 2 days use.
Go for it but don't do any playing before installing custom recovery ( CWM) and making a Nandroid backup.

The Skyrocket has respectable battery life, consideeing its LTE and 4.5",screen. A ROM is not yoir solution to getting extended battery life out of your phone. While some ROMs are more battery friendly than others, there are better alternatives. Juice Defender seems to be really popular and successful at prolonging battery life.

Here's a link to the thread. I'm sure there are others like it. I definitely learned a lot:
http://forum.xda-developers.com/showthread.php?t=1524291
Needless to say before any of that is done, you wanna make sure the following is done first:
1. Make sure your phone is rooted and have Clockwork mod setup.
2. Do a nandroid backup.
Hope this helps.
Not new to the sensation but new to this account. I have decent knowledge for this phone but seeing i have to ask questions, i might as well take advantage of it. seeing my phone is having such crappy battery life, even though it isn't mentioned in the kernel thread. If i have crappy battery life after installing a kernel several times with the same rom i used it with before and had great battery life, would it help if i recalibrate the battery after flashing the new kernel. I know this is said to do with alot of roms even though it is built in to most roms now, but it is not mentioned as a possibly try in any of the kernel forums and would like to know from someone with alot of kernel knowledge if this would be safe and something that might help.

I usually wipe the battery stats after having flashed a rom and not a kernel...

Battery stats are automatically wiped when your battery hits 100%. The process of manually doing it actually does nothing.
Hello everyone, I recently went from the Revolution HD rom to the ViperS rom. I had flashed the radio and firmware required (stated in the rom's thread) for the Revolution HD and didn't see anything stating I should flash a different firmware when changing to the ViperS rom.
Now I have noticed my battery life has been reduced tremendously, where on the old rom I could get a day of general use this struggles to last 5 hours now. I have changed the governors and settings for ViperS and reflashed it many times but nothing has changed. Am I missing something here?
You might have to re calibrate the battery.. this can be done by wiping battery stats after a full charge in 4ext touch, or using a battery calibration app from the play store.
Hope that helps

Wiping battery stats is actually useless, it auto wipes every time it hits 100% and doesn't actually offer better battery life. To calibrate, just charge all the way up and discharge all the way down two or three times.

If I see another misleading post about wiping battery stats I will bang my head against the wall in frustration. I dont know how many times Ive said it, IT DOESNT HELP. A google engineer even said as much and gave a full explanation on G+ (google it if you want more info).
Sense 4 ROMs naturally have more battery drain than Sense 3.6 for some reason. To calibrate the battery, charge it to 100% then let it discharge to 5% then repeat 2-3 times. For some reason ROMs need a "settle" period
This is interesting because this Rom has given me the BEST battery life I've ever had in a Rom. Have you tried disabling the logging feature in the settings? This might help a bit. Also perhaps it does need to settle a bit. I've been reading and it's about 50/50 some are getting great battery life like me, others are not....I'm not sure what the differences are that some will get great results and others not. Maybe it's in the settings.also I did not flash the new firmware...

Okay I will give it more time to see if the battery just needs longer to adjust and I'll turn off logging.
Hello everyone and thanks to all the developers for the knowledge.
I've searched in the forum but still can't find the answer, so I have one question:
I bought a new battery, wich is still in the blister. I've already flashed my phone before (specifically Infuse 4g) with Custom Rooms, and had no problem.
My question is if it's good to use the new battery and flash the cellphone after charging it completely (i've read already battery university and pages like that for the health of the battery), or, if is it better to keep the actual battery, then flash, and then change the battery for the new one.
I know it's possible to re-calibrate the battery after flashing with programs, but I also believe that the first charge it's extremely important for the new one, and the stats for the previous one might affect the new one.
What would you recommend?
Thanks.
I think it's good to use the new battery and flash the cellphone after
charging it completely
You should def go ahead with the new battery.
There is nothing related with battery and flashing roms
Only sometimes you may get calibration problem which can be simply calibrating battery by using battery calibration app from playstore or deleting battery_stats.bin file

It doesn't really matter to much when you flash the rom, just i would clear the battery stats after you flash it just to be sure.
