I'm currently on DK28 and my battery life is horrible compared to what I used to get on DI18. On DI18 I would lose about 5-10% overnight but now I lose about 40%. Is there a rom out there that can increase my battery life significantly? If not what would you recommend me to do?
I recommend you read "how to train your dragon" from the dev section and the other battery threads already out there.
DK28 shouldn't lose that much juice overnight. I lose about 9-12% overnight on DK28.
There are no DK28 roms that improve battery life, but there are DI18 roms that undervolt. We can't do any of the overclocking or undervolting until we get source.
You can turn off 3g by pressing the power button. That's done miracles for me.
2.1 couldn't do that for me befoe. 2.2 did it perfectly.

The battery life doesn't seem to last too long compared to the stock froyo rom or even the 2.1 rom that came with the phone after the update that increased battery life.. is there anything I can do to increase battery life? Thanks
Sent from my PC36100 using XDA App
how long do you need it to last? 12-16hrs w/ moderate use is fine for me because it gets a charger every night. are you away from one that long?
I'm getting 20 + hours with cm6 with moderate use but I have to agree 12-15 hours should be plenty
Have you condition your battery? Are you undervoltin etc etc
from the fade
ha! must be doing something wrong, this ****s all over the stock roms battery life
went whole day playing with cm6 and didnt need a charge
Every kernel that I have download that is suppose to increase my battery life actually drains my battery very fast. Why is this and what kernel do you recommend?
A few things here. Give any kernel 3-5 days before you judge its battery life, more often then not my battery is awful after a kernel change for a few days then picks back up and works as its supposed to. Make sure your battery is fully charged (power off trick) and clear batt stats after fully charged.
For those that claim they lose only a percentage point or two of battery overnight can you tell us what exactly you are running or doing to get those results? I'm using the screen off profile in SetCPU and after 8.5 hours of sleep the battery goes down around 20 - 25%. Running Baked Snack 1.8 with Kings bfs #9. Should I be seeing better results than that?

The screen off max/min 245 should work. I use that and it works wonders. I also use some advanced settings to help out while my screen is on. My battery doesn't drain as fast anymore. setCPU is a monster.

baked snack and kings #9 should be a good combo for battery life. (kings #6 bfs was better for me).
you probably have an app not allowing your phone to sleep. check out the apps system panel or android system info to see what app is keeping your phone awake.
edit: also, are you on wifi or 3g overnight? wifi will significantly drain the battery LESS since it doesn't constantly search for a better signal. do you have a strong 3g signal?

I never use wifi at home but I keep 4G active since I get a great signal. Should I just turn that off overnight?
Hello everyone, I lately have been getting horrible battery life!! I keep brightness on lowest setting, use wifi when possible, turn down haptic feedback all the way etc. do my best to save battery!
So my epic is Rooted with CWM3, and the latest frozen syndicate rom installed. Is it because my phone is rooted and the syndicate rom drains it more? is that why i have bad battery life? Does having your phone rooted drain battery life?
I ordered a Seidio 3300mah battery and got it yesterday in mail. Put in phone, then charged rest of night about it. Im using it today and am still receiving poor battery life, my friend who has epic ordered a cheap hong kong battery and is getting better battery life? I read something about conditioning your battery and draining it to 0% then charge fully to 100%? How does this work please explain?
Can someone just please help me use my new battery to its potential and help me out here?
Draining your battery for battery calibration is unecessary... there are a few threads regarding it...

so what should i do to improve battery life?
Rooting and custom ROMs reduce battery usage. You need to supply more details. Are you overclocking...that burns up battery usage. Have you tried Spare Parts to see what is using your battery? Has 3G been out in your area and the phone is searching for a data signal?

im not overclocking. spare parts? 4g is off- not in my area. 3g is on. what should i do. should i use my phone reguarly till it drains 0, then fully charge? i read something about wiping battery stats, shud i do tht? and i also read tht ec05 is horrible on battery life. should i go back to eb13 possibly or wht? and recommended roms?
try this thread:
Calibrate Battery thread - This is how you do it!

I used "The Powered Off Charge way" method and it did seem to make a difference.
Hope that helps, good luck

I have noticed no difference in DK28, EB13 or EC05 in my battery life. Do the calibration suggested in the post above. As for ROMs it is about personal choice. I have been with Bonsai for awhile now. I hear the ACS ROMs are very stable. Syndicate Frozen is good, Midnight is good. Read the OPs, learn what they remove and improve and see if that is what you are looking for.
Running SRF 1.1, with a custom theme, brightness at lowest setting, haptic feedback all the way up, because I need to know if someone is calling, I regularly get 30+ hours per charge. The two Chinese knockoffs I have get about 26 or so hours per charge.
I have recently seen a drop in my battery, spare parts on a couple of occasions should my phone would not sleep. Sometimes a reboot would fix this, but reflashed just to be safe.
After the reflash I was still getting bad battery life but spare parts showed no issues, so I started doing the airplane toggle again and that seems to of fixed it.

whats spare parts?
Spare parts is a free program available in the market place. It shows you more detailed statistics on what is using your battery juice.
Undervolting maybe. But I got stablilty issues. ymmv anyway.
My advice is
1. Set max clock to 800mhz and min to 200mhz. The CPU is volted -75 over 1ghz and 200 is volted the same as 100mhz. I use the Conservative governer but Ondemand works well too.
2. Get a good custom rom/kernel. CM7 and Frankenstein got the best through all my testing.
3. Brightness at lowest, turn off "Notify me when Wifi networks are available", Turn off syncing for contacts, the two GPS options, etc.
4. Take out as many applications as possible(Personal preference. I think it makes a difference) But I mean stuff you don't use. I take out Bluetooth, GPS, DRM, SNS, and most stock applications. If you're using Handcent you don't need stock SMS and vice versa.
5. If you're on 2.2 and lower I recommend a program like JuiceDefender to turn off 3G when your screen is off. The latest update on the free version removed the option to filter applications using data while the screen is off.
6.Enable Airplane mode on boot up. Then turn it off and use normally. TWS
7. Definitly calibrate your battery.
8. *Insert unreasonable battery tip here*
Oh and spare parts can be installed directly from the market. It's a program that allows monitering and for changing animation speeds and such. I don't use it for anything. You should also be able to go into settings -> about phone -> battery usage and see most of what spare parts would.
is tht one thread the one guy posted to calibrate the battery? will it work?

Especially with a new 3300mAh battery! I recommend the top two as the third didn't work for me.
Juice defender on aggressive mode and setcpu on conservative mode increases my battery life when on standby quite a bit.
Don't drain your battery to zero it destroys our batteries. Don't use juice defender. If there is no reason that you need background data on like when you are sleeping turn it off but some say that's cheating but their idiots. That will dramatically improve your battery alone. Do the airplane shutdown every once in awhile some that's cosmetic but don't believe everything that is told to you. Only keep apps installed that you regularly use. Use spare parts to see if any app is causing significant drain. I'm a battery life guru.... ;-)

Last night I switched over to the EF02 Gingerbread leak and flashed the AA i3 rom.
I was loving it, but my battery went down about 15% in 20 minutes. Just while going through menus.
Browsed around a bit and found out about calibrating the battery, and how it can fix the issue.
So, my questions:
- Should I calibrate from a full charge?
- Is it a good idea to calibrate the battery every once in a while, just for the sake of it?
- What kind of battery life have some (any) of you seen out of the AA i3 rom with a properly calibrated battery?
Thanks in advance.

calibrating the battery is just a placebo effect in my opinion...i don't think it will help you at all
my personal experience with ef02 is it tanked my battery in 5 hours from 100% to dead
i'd recommend sticking with ec05 until we get a newer leak or official gb
go to market and look for battery calibrator and then i t will tell you directions from there
Could be ROM. My wifes epic is deodexed ef02 w ef02 modem and a few odds and ends and we are seeing 12hrs on a charge. When it was same ROM and ec05 modem...it made it 4.5 hrs w hardly any use and died.

That was kind of the suspicion I had...something sounds kind of off about "calibrating battery".
Even if the leak was making it 12 hours, I'd still have switched back to EC05 2.2 on SRF 1.2...which I already did. I'm very content with a reliable 20+ hrs.
Was fun to toy with though, definitely left an impression as far as things to look forward to. I'll keep waiting for a more stable/official...
Also, root explorer. Data/system/battery stats.bin. delete that file after full charge, meaning full charge, unplug, plug back in for 15ish mins. Reboot. Simple. You will be deleting the battery statistics manually and upon reboot it creates a new file. If you are paranoid about properly doing it that will do it.
Rodderik, nice to see that name more often again.

I had great battery life on EF02 Plus.

I just went back to SRF 1.2 to try it out might go back to EF02 Plus. No knock against SRF1.2 it is great ROM.
Make sure your phone is in deep sleep mode.

I am current running the Bonsai Rom 5.0.0.B12 and I am greating great battery life. Make sure there is nothing that is preventing your phone from going into deep sleep mode. Background data, also make sure that your cpu settings are on conservative. I use voltage control to change my cpu setting to conservative and noop and I use cpuspy to determine if my phone is going into deep sleep mode. If you do these thing you should get great battery life.
I previously had amazing battery life using AA i3. However, after installing CPU Master and setting it to ondemand I've been getting steady battery drain (much more than previously.) I've tried reflashing it along with other EF02 roms and still get the drain.
I'm not POSITIVE that they're related; the only other thing I did around the time I started having my battery drain was install Google+ but I doubt that it would cause drain to the extent that I'm experiencing now. How can I get back my amazing battery life?
PS. I've been using the EF10 modem the whole time; including when I had great battery life.
Never mind, it looks like I ended up with the EC05 modem somehow. Will I have to recalibrate my battery after flashing the EF02 modem and upgrading to EF10?

You only get 2 or 3 hours on a full charge? There is definitely something wrong with your phone. I run Pandora over 3G for 5 hours with bluetooth headphones and I still have over 50%. What is your setup like?
I found that if you restore the Froyo voicemail on EF02 leak it eats the hell out of your battery. Mine got real hot too even after reboot and stopping the service. Had to remove it.
