So i flashed the stock leak to 2 of my coworkers phones a few days ago and their battery life went up BIG TIME..now i flashed it to mine + installed EE.
last night when i got home from the bar and passed out i left go chat running all night and when i woke up my battery was at 75% - with go chat running for 8 hours. normally my phone would be dead. Im really, really impressed with the improvements in the DK28..
Anyone else seeing similar results?
Why not post in the EE thread?!
What's EE when I was on dk28 my 3g radio was trying to upload constantly and killed my battery in record time. So I'm not running it anymore only because of that. If this EE thing can bring my battery life back to normal I'll gladly give dk28 another try.

I'm surprised theres no sticker for a guideline on what to post on Development, though I guess common sense is supposed to be a factor.

What exactly are you developing? Is this a rom or did you really make a general post in the development area?

I have noticed the exact opposite w/ DK28... I was running DK05 before and had great battery life, now w/ DK28 its back to just a hair better than it was Stock.
Although this is in the wrong section I also noticed much better battery life with DK28.

I have had much better battery life as well. No where near the advertised specs but significantly better than DI18.
can a mod plz move this so i can stop spamming this forum?
LOL. I'm definitely not seeing these results.
My battery life lasts me pretty much most of the day off the charger with some heavy use here and there and I'm still on DK17 ViperROM 2.6 with auto brightness on and a few widgets/notifications every 3-4 hours.
Does your gps work going that way? And if its much better battery life ill have to try doing it. As for those saying it is spamming, it may be but instead of trying to act like you have power actually contribute to the thread.
There are so many threads like this. Can we get a mod up in here?

Epic Experience.....a rom.
With DK28 and EE I have had 26 hours of battery life, the first time I have had over 15 hours ever with my Epic. I am honestly comfortable walking a round without worrying about where I can plug my charger in at.
Threads like these (including their responses) are why post count doesn't matter.
Please post questions in General section.
Ok, first up I am not a developer, not would I know how to develop for the phone.
With that said, I've noticed a repeatable chain of events that I think have caused at least in my own situation poor battery life from certain modems.
I noticed that after flashing for instance KA7 on top of a previous installation of KA5, KA6 or even JK6 that battery life of the new KA7 modem was horrific. My base ROM was usually always Nero or Bionix
Then I completely changed to the new Bionix-V ROM which is based on KA7 and voila, my battery life is great.
Could it be that the process of flashing different modems causes some kind of internal confusion with the phone that relates to undesirable battery life?
Just an idea, but it's like I said something I have been able to repeat, and perhaps others have had the same experience.

Instead of responding with a useless post and armchair modding, you could just not post at all and let the moderators do their job. It's posts like yours that cause people to run out of here. Just blatantly rude.
I don't know, but I think it's possible. Sometimes, flashing over causes every kind of problems. Why not?
Isn't that the reason why we clear battery memory after a flash? So that there is no confusion. :-\

Never underestimate the power of placebo
Reset the battery stats via recovery and after a full cycle or two you probably won't notice poor battery.

I should have added that I ALWAYS wipe battery stats when making modem/ROM changes - following the usual guidelines.
However, my experience still exists.
Specifics:
Nero V3 Running Voodoo+JK6 = Approx 30 hours battery on light/medium use
Nero V3 Running Voodoo+Updated KA7 = Approx 12-16 hours with same usage
Bionix V running Voodoo+KA7 = Approx 30-36 hours with same usage
It's not placebo - it's a measurable, noticeable difference.
i get good battery ;life out of stock ka7 no bloat prolly around 30h and for instance i had bionix and my battery was sucked up llike no tomorrow thats why i am back on stock
I think the PLACEBO may more correct answer, Since JK2 and on battery has been not a real issue. Every time you flash a new modem etc, if you think you need to (I do not think it is all that important) go into recovery and go in advanced and do the clear battery stats and go from there......
The only Time i have ever had a real issue with the battery life with custom ROMS is when using over-clock roms.
Other than that, I would guess you are using the phone different every day, and do not think so imho. That is a more likely cause of battery performance or lack thereof.
with bionix my battery lasted half less
Is has a lot to do with how much battery you have left when you flash a rom. I always flash with a complete full charge and never really see a difference in battery life going from rom to rom. My battery always last about a day and a half with every rom I have tried. Also I have not once wiped battery stats. This is only needed if you do flash with a battery that is not fully charged.

I apologize but take away about 10 hours of just idling while your sleeping at night, that doesn't count... I could keep my phone asleep with no widgets, 0% brightness, etc. but what's the fun?
As long as your phone lasts you the day, or as long as you need it to, you shouldn't be worried about it going for a week on one charge...

exactly.
Your battery needs to last maximum of 15 hours, unless if you work 24/7.
your going to end up charging it at night so why the hell do you care?
I'm curious about the 20+ hour battery life cases if you have background sync enabled.
I just requested a new battery as my old one I believe is going bad. Running JFD --> JK6 --> JK7. Charged battery to 100% while off over 3 days. (Letting sit all day at 25% 75% and 100%). Resetting battery stats tonight and staying at 100%. I'll see how the new battery compares. (My old battery life was 8-10 hours max).

Na I would rather use my phone as it was intended a smart phone. One should get a day out of it Then plug it in at bed time.
Not sure if this is in the right place for this info or not. But...I flashed myns synergy rom a couple of weeks ago and have been getting decent battery life. Today my battery life is blowing me away. Going on 11 1/2 hours since being unppugged with my normal usage. Not heavy use by any means but moderate at least. I have never seen this kind of battery life on any other rom I have flashed. Any other synergy users seeing good battery life?

Yes, from what I have read, you have to use the kernel that comes with the rom.
I am getting HORRIBLE battery life with the synergy rom....almost to where I cant use it. I LOVE the rom, but the battery life is frustrating!
Hopefully Netarchy will develop one that will work with this type of rom and we will be saved.

You will be waiting, cuz no custom kernels can be made until the kernel source from HTC is released.

About 100 texts total, a handful of phone calls, lots of checking of XDA, FB, Twitter, Google+, etc. was on wifi entire time.

I'm using syngergy kindgom and have been consistently getting a full day on heavy usage to almost 2 days on moderate usage from the day I flashed it. You guys should try that and I feel like it's quicker than the original synergy.

I tried that for a bit over the weekend...but there was something I did not like about it...cant remember now. I will have a go with it again to verify.
At the end of the day...we can develop superb ROMS that have flashy flashes, but if the battery/components cant take it, then we are still at a stand still.
my battery life is good most of the time, but it seems there are periods where it drops quickly. i think it drops when the market alerts me about updates to my apps. both times i've had quick drops, the market has been the top app draining the battery and has a notification of updates. i don't see an option to turn of notifications is this updated version.

No but the netarchy kernel I use works just fine with my King's Alliance GB. It's all in the UNIVERSAL kernel, I should say
I usually get 24 hours up time and 3 hours awake before I've got to pop in a charged battery. Normally change out at 20% to keep it from going dead on me when I need it most.
Hi, my s2 is using villainrom 1.4 as an attempt to improve battery life. At the moment i am on 50% battery after 4 hours and a bit with screen on time at 2 hours. Even with moderate usage i hav never gotten over 12 hours...
Could someone give me tips how to get my battery to at least a day, desperate for help. I have auto sync off and use a mixture of wiki and 3g.
I will post the screenshots of battery later as i dont have enough posts yet.

Try to uninstall all apps you have installed and see if you get some improvements, then install one, test again.
I found that NetCounter kicked in on my SGII and the phone never went to sleep, just screen off but it was awake and drained the battery in 12h
//Mike
I will try and post the sreenshots soon. It seems that awake and screen on is largely related. I may have to factory reset and see how the battery fairs then.
I did a *#1234# and saw my csc is unknown? Do u think there is somethin wrong with my modem? It seem when wifi is on it always drains the battery alot faster.
Ia there any app to monitor how much drain apps cause? Thanks guys

since you say you had the screen on for 2 hours, your battery seems correct. other people on this forum are claiming they get 4 hours of screen on time from a full charge. so if you had 2 hours and 50%, that seems right in line with proper results.
I dunno man, just gingerbread itself appears to have fubared my phone. I wiped sd, wiped phone, factory reset, odined stock EC05 and took the forced EI22 update. Even still, android system chews through battery at >90%. A small thermonuclear power plant could not give my phone enough juice.
This coming after I tried multiple combinations of roms, kernels, uninstalling apps, and freezing data sucking apps that caused high wake locks....
I have tried stock gingerBreadEI22, ACS 3.5 - 5.5, ERA RC1 & 2, and Random Rom, with nubernel, different samurai kernels, and just whatever the chef cooked up. All the same, excessively high "system" battery usage.
Anyone is / was having the same issues and able to iron it out?
That reading for system is the norm. I get 24 hours with like 80%

I agree with Alkah0liK, but with my experience so far, if I don't use the phone all day it doesn't really use the battery, but as soon as I start talking, listen to music, or web surf it because a pig. I actually want to go back to 2.2 and use frozen rom again from ACS again. Can't figure out how yet though

Ok thanks, I was wondering what others were seeing.
I must be doing something it does not like. I can go a couple minutes with the screen on (at lowest setting mind you) and watch the battery drop 2-3% or more, almost dead battery within 10 - 12 hours even in /out of airplane mode...
Is there something really wonky with CWM? Funny thing is this started happening right about the time i switched over to v5. I am in the process of reverting back to wiping everything, odin to EC05, and going v3.1.01 again.
The battery life is better with gingerbread, but its not going to make your phone run 2-3 days on one battery life. Sorry my friend, those days are long gone. It would be very hard to find any cell phone that can run for longer than 24 hours these days.
No I get that, but I was able to use my phone for more than a couple hours a day before gingerbread. B4 the leaks I was running Viper Rom EXT4 with genocide at 1200 ondemand and still getting through the day. If I cut it back to 1000 and went easy I was only charging overnight to bump it back up to full.
I was even using RandomKing's and ERA's leak based roms with EH06 & EH17 without any issue. For me it really has been either the EI22 / CWM5 / latest roms.
Hey alky, I was also in your position. I tried every rom you tried, with minimal pleasing. My advice, if you can live without 4g, flash the current cyanogen and set the render effect on night mode. Enjoy a thorough battery life my friend. Nothing beats it thus far. Can't wait till we see cm9.

Thanks! That was actually going to be my next try. I only get 4G when I am downtown, not very much as of late anyway.
FYI- I have found what I suspect as two possible culprits on ACS 5.1 & 5.5, and ERA RC1 & 2. According to better battery stats CM_VnoteService and *Sync for GTalk will run and run and run unless you open the applications and go through initial setup. Those two process will stay stopped so long as I leave them open / connected, once I close them - the partial wakelocks restart and run until you open the apps again (or just uninstall).
Even with my obsessively high amount of .acore launcher time and better batter stats application usage, they are still well below the "system" usage under the process dropdown.
It definately sips battery when not in use. Although I feel I get more screen on time with ACS ICS. I regularly have over 3 hours of screen on time with GB, I don't remember getting 3 hours on even SRF 1.2.

Turn off your syncs. If there is no signal your syncs will keep trying and burn up your battery. Turning off data mode in low to no signal areas will conserve battery.

Make sure upgrading to GB did not change any syncs. Also make sure new apps aren't loading into memory and sucking battery like Talk or Google +. Grab Memory Booster lite and pull up the task killer to see everything loading on your phone. The stock task killer sucks.
I recommend paying the $50 for battery and portable charger/storage unit. I'm a stock user who just had 41 hours with my new battery with 2hrs of screen time. I really like having two batteries too. No more charging cords connected to the phone...ever
Edit: the batt. I bought was a stock 1500mah batt. and charger kit from a sprint store. No regrets

Still running 100% ERA Legendary v4.0.1 (with provided kernel) and I squeezed ~74 hours of pure standby time out of my stock battery.
Data Sync (FB every 6hrs, Weather every 2hrs, Google push)/GPS/Auto Brightness = on
TWS = 4%
Display Time = ~24mins (sent 3 texts and checked 1 voicemail)
100% on 3G
Had I turned off all synching, GPS and lowered brightness all the way, I would have probably gotten 4 days.
Battery life has heavily depended on the strength of signal for me as well. I moved recently and have been living in the basement while the renovations are going on upstairs. No airave (it is used at a different location) means little to no signal in a brick house due to Sprint's POS signal frequency. Although I've been flashing different kernels and maybe not allowing them to settle + undervoling a bit (very conservatively, will not OC over 1100). But it is true that since days I was on BB Tour, not one phone lasted a full day without an extended battery. I'm pretty much decided on VZW switch once Prime comes out - one of the factors is better expected power management of ICS and possibility of adding an extended battery without worrying about making the phone too bulky (given how thin it is).
Man that sucks, I've always had great battery with gingerbread. Right now I'm on RC2
