Gingerbread improve battery life? - EVO 4G Q&A, Help & Troubleshooting

Anyone know if battery life will improve at all with the new gingerbread update coming tomorrow? I'm just curious to see if they helped improve that at all, knowing that alot of people are currently running 2.3 already.

There probably won't be a big increase in battery life, but what this does mean is that there will be source for GB Sense kernels for the EVO. This is great because then kernel developers can start cooking better kernels that offer more battery savings.

I certainly hope so, but I wouldn't count on a major increase.

I have an extended life battery on my EVO. It has always allowed me to use the EVO as much as I wanted as long as I charged it nightly. Since I installed Gingerbread, my phone will no longer make it all day. Gingerbread actually made my battery life much worse. I wish I had never installed it.

Well, every update I'm sure has some specific things that optimize the processes the phone runs and the task killers, so there's probably some minor improvements. I doubt you'll notice all that much though . If you're having issues with battery life hit up my sig lol

my moms evo had a problem with battery life. Some how it wasnt charging correctly. A battery pull for a few minutes fixed the issue.

Had the same problem it would charge for some time but then stop charging..but its fine now

I've been running GB now for almost a week and I definitely have quite a bit worse batter life.

I installed a rooted gb rom last night and updated all the radios. Runs smoothly but my battery life has significantly gone down. Does anyone know if there is a known display issue with the update? See my screenshot of my battery stats.

My display totally eats my battery on the new update. Very lame
We're comin from a pure power source.

Retraction to my previoius post in this thread
I found an email with a rather large attachment in my outbox that my phone was continually trying to send. When I deleted the email, my battery life returned to performance that was similar to the performance I had prior to the GB update. I believe the phone was continually trying to send the email and it was swamping my battery.

[Q] Best kernel for CM6?

After realizing that I made a mistake by ditching my EVO for the Epic; I returned to the EVO and installed CM6. What a difference! Everything is great so far except for battery life (even using profiles on setCPU) so I was wondering what kernel would provide speed, reliability and battery savings. I'm currently running CM6 kernel and I'm getting around 1250 on quadrant (around the same results of the nexus one with froyo) so I'm happy with the speed so far but I would love some more battery life (I'm getting less than 8 hours with moderate use).
Thanks
What I learn is try a kernel for a day or two. Try another.. you will find one. Not saying do this but this is what I'm doing. Just like finding a rom.. always come back to cm6

Geez, my bad. For some reason I thought I was in the general section.
Can a mod move this thread to the general section? Thanks
Before this gets moved.. all hardware is different. On paper its the same, but what we have learned is that phones respond differently to the software thrown at them. As others suggested, try them out. Snap as well as Kings are excellent kernels. Just find there threads and I can't stress enough to read the op. Most of the questions you have can be found there, as it can be a little cumbersome with all the different versions for some. But yeah, make sure to give it a run for a few days before you decide its not working for you. Your phone needs to get used to it, so basing it off a charge after a few cycles is always a good idea.

Run Snap v7.5 for an increase in speed and battery life.
King's Kernel all the way, and I've tried all the damn Snap kernels.
Mostly, you should be managing your wifi/3g/screen off cpu settings.

I've been using King's #1 kernel after trying (and having issues with) a myriad of Snap kernels. I really like King's and am waiting for #2.

[Q] Crazy Battery Loss on CM9... help?

Hey let me talk to you for a sec... dont take this the wrong way but are you the only one in the forum that does not know all ICS roms have terrible battery life until we get kernel source.....Bad battery life is notated on like every thread in ICS.
Its ok man just messing with you but yea until kernel source comes out either deal with it or go back to GB... Oh yea and try and polish up on your ICS knowledge for the future

I dont know about all that I am on CM9 as well and I get the same life maybe a little less than I did on the gingerbread roms. I easily make it through a day with heavy use with battery life to spare. It must be a rouge app.

Hey if you are making it through the day then what the heck are you complaining about and with heavy use.... Come on man! Get Better Battery Stats and figure it out...
I thought you had real issues...lol
I know about the battery issues, but I have never seen a drop like in the screenshot I posted. I don't know if you looked at it, but I have not read of a reason for this to occur. It drops somewhere around 30% immediately

Simple man the kernel sucks life out of your phone when custom kernels start flowing so will your battery life.

I solved the problem.
I have three batteries.
Sorry to bring up a dead topic but since these issues are still rampant and there is no "official" fix thread that I know of, I thought I'd post my findings and fixes that I have come acrossed (I take no credit for any of these methods) after taking these steps, my ics battery issues are gone.
Backup anything you don't want to lose.
Do a factory reset from the privacy settings.
Format internal SD AND external SD under storage settings.
Change wifi advanced setting "keep wifi on during sleep" to never.
Turn off display battery percentage under display settings.
That's it! One or more of these methods fixed my issues, I was having next to all of the problems people are having. Including the random massive battery drops mentioned in op.
Also your notification light and battery light could drain as well.

Which Rom Offers the Best Battery Life on Jellybean?

I know im going to get flamed on this for making 'another better rom for battery thread' but ive been away for two weeks and i see some new roms are out for jellybean, i am currently rocking AndroidMe Cm10 rom, but would like to try a different rom for better batterylife. (its not the best as is ..) i know you guys are going to say every device varies but chances are what most people are getting better battery life on so will mine... so what would you guys reccomend? i really dont want to revert to TeamGummy 4.0.4 (ICS) but if i cant find a better batterylife
well, a better battery life is mostly up 2 the kernel, screen brightness, wireless and network usage, other settings r just familiar of most roms.
though ice has a better battery life than jb, i think
the GUMMY doos have a good battery life 'cause it's using the imoseyon kernel:good:
Noooooo!!

Not trying to flame you but you answered your own question in the OP. Every device varies along with the way each person uses it. I don't have any technical expertise to fall back on when choosing a ROM so it's mostly a trial-and-error process. Flashing a different ROM or kernel is fairly simple, so just experiment and see which one gives you what you are looking for. I rarely, if ever, got the same performance that other users reported when I had my Evo. And lastly, read what other people are saying about a particular combination. XDA has no shortage of people willing to try out new things and let the rest of the community know how it worked. The last 3 pages of a thread are usually the best place to look and see what kind of success/failure rate is happening.

*sigh* just look at the kernel threads and youll see, its not like there's 70+ kernels

[Q] Battery life on CM10

I'm really curious to know what the battery life on CM10 is since I used to have FF18 and I have to say that it wasn't as great as I expected it. Right now I downgraded to EL29, mainly bc of battery consumption but I want to know other people's experience with CM10.
The cm 10 battery life will vary..for Me Jb battery life is fine..with a little effort it is very possible to get good battery life..was it as good as ICS.?.honestly no..but ICS has source for our device and source for in on our device hasn't came

I barely even use it AT ALL, and battery is at 32% after less than 10hrs. Also, playing Bad Piggies for 30mins, and it'll go from a full charge to 12%.
ICS wasn't any better for me either, but I think JB is a tad worse...
im running nightlies from phantomphreak and im getting 13-15 hrs average. thats with moderate usage. best thing you can do is set it to 800mhz max and conservative. everything still perfectly smooth for me
heres my battery life with the latest nightly from phantom freak. cpu set at 800mhz max with pegasusq governor
absolutely terrible lol i gotta charge it like 2-3 times a day

Since there is no info in your post, no one can help.

What ROM do you guys experience best battery with?

Just wondering, what ROMS have you guys tried and genuinely thought "Wow, the battery really is good".
I've been trying Renovate since version 8 and battery on my device has been pretty poor, on AR-HD it's quite regular, don't have any issues with it.
I'm sticking with Sense and haven't tried any other Sense ROMS and that's why I'm asking.
Also not planning to switching to AOSP ever.

Just downloaded it and going to flash it right now, thanks for posting.
I've read in the thread an update is coming though, any idea what the changes/fixes will be?
I think ARHD V9.7.2 have more stable and better battery performance to JB ARHD 16!
I have over heat issue with that!

I used ViperX for a long time. That has always given me the best battery life. I've even been able to get up to 6h of screen on time with heavy internet use.
If you're looking for a JB sense ROM, I had great battery life on both InsertCoin and OrDroid. Nowhere near ViperX, but still good.

Had a PM asking how I manage to get 6 hours of on screen use and thought my reply might help others, so I'm going to post it here too.
"Hey man,
That was with ViperX 2.7.1 running the AOSP theme.
Yeah I've had 6 hours, or near to it, quite a few times now. I actually use the stock kernel included in .zip.
I also desense the rom and mainly use the phone with about 30% brightness. Also, make sure feed sync is switched off in Facebook under the accounts and sync area in the settings because that's an absolute killer. I still have Plume and GMail set to sync almost all the time, but with Facebook on, it totally destroys the battery. If you want to sav even more battery whilst increasing battery life, switch everything to manual sync.
ViperX is an excellent choice. I've used loads of the new JB sense roms and none can compare to ViperX for battery life and the excellent mods included.
Hope this helps."
