I really hate creating these threads because it makes me look likr a complete noob but I can' figire this out for the life of me. I bought the charge thinking I could use it for a day and change but I have yet to experience this awesome battery life. Even when I got my first day, the battery life was horrible and even after its first charge, it wasnt any better. Do I just have a bad battery or something?
Heres what I remember doing:
-Flash gummycharge day 2 of owning phone (1.8.5) novoodoo kernal
-An issue came up where I couldnt press my power button without the phone freezing
-so at this point I reverted back to a stock ee2 rom
-i then flashed gummycharged once again (same as above)
-after flashing, I charged my battey up, shutdown, wait for 100%, repeat 3x to wipe battery stats/calibrate my battery
So I unplugged my phone at 5:00pm and it is now 7:07pm. In two hours with about an hour of browsing, my phone is at 73%. I have nothing on any of my homescreens just to be sure it wasnt consuming the battery, cdma automatic instead of 4g lte since my area does not support it yet and manual brightness at 15%.

Download humble 1.25 and your battery woes will be no more my son....
Will take you suggestion and try it out tonight. I dont mean to derail my own thread but is it possible that when I flashed back to stock ee2, it caused my signal to decrease even though I put gummycharged over it later? Ever since I had to reflash because of the power button issue, I noticed a decrease in signal strength (from mid 80s to high 90s). Sorry for all the questions!

Hi,
I saw your Humble ROM and was considering installing it to try to improve battery life as we'll.
What about your ROM conserves battery over the stock rom?
Now that p3droid released 2.3.4 I will certainly have to try it, do you plan to make a version of Humble using this new base?
Thanks for your work, I really am loving this new phone!

If you are getting that bad of battery life, go to EE4 Debloated . Flash P&J OC Kernel. and Undervolt your phone.
Whay would be causing this kind of battery life though?

No telling, depends on how you use your phone and what apps are running.
Thats the thing. I haven't been doing anything other than browsing. I only went to class and browsed for maybe 2 hours max. Everything else is 2% ish other than the dolphin hd browser. If I look at the battery stats, the display is the only thing thats depleting the battery really. I'm starting to think its because I have weak coverage in my area.

I've had similar battery issues with two different Charge units running each ROM/Kernel (except GB). I also live in a weak coverage area where I average 1 to 2 bars, sometimes dropping to 0 and i'm convinced this has to be it. I had written this idea off initially because I previously had ATT and the same weak coverage with them, but nowhere near the same abnormal battery drain...so I guess there must be a difference between the way CDMA and GSM operate in this respect? I'm in a 3G only area and keep the phone locked to CDMA/Auto also.

I am running 1.25 and have had absolutely no improvement to my battery life (strong 4g area in SoCal).
I've just resigned to the fact that I'll get 6-7 hours (even on an extended battery, same results) and have to charge once or twice a day.
Coming from the fascinate I honestly think the battery life is better. Although I turned lte off since we don't have any coverage for it yet. My mind will probably change when we get it. Running stock ee4 rooted with voodoo kernel. My father is running the same thing and also came from the fascinate, he completely agrees.

I had really bad battery life on my phone running the stock rom and gummycharged. With the phone sleeping and only data on, I was losing at least 5% an hour.
I switched to Humble a week ago and my battery life is exceptional. I am ususally looking at 24 hrs with 4g on and longer with it off.
If you do a lot of browsing and keeping your screen on, your battery is going to burn quickly. No matter what ROM you are using. If it's draining a lot of battery in sleep, flash Humble.

Dude, this isn't the fix. I'll flash Humble 1.25 right now and prove to you that it doesn't fix battery issues. Yes, it's less of a battery hog than the other available ROMs, but flashing Humble 1.25 will not fix your battery gremlin.
I wish Danalo, imnuts and the other gurus would spend more time figuring out this battery gremlin. Charging your battery to 100% then wiping battery stats through CWR doesn't work either. I've tried it countless times.

Don't give up so soon. The battery life on the Charge can be amazing and I know from experience. My experience also shows that there are funky battery issues that pop up when flashing various crap. Flashing an Odin bundle has not worked for me, at all. Wiping battery stats has not worked.
I was running GummyCharged 1.5 with the PBJT kernel and voodoo enabled and got 17+ hours of medium-hard use EASILY. Since then, I flashed the original GB leak, Gummy, Humble, Stock... I cannot figure out what the heck is going on, my battery life is still crap.

It really sounds like signal issues to me. My Charge handles weak mobile signals better than my Thunderbolt, but any cell phone will really crank up the juice draw looking for a tower if it can't find one. In my north county office, my Thunderbolt will drain 25% per hour if I don't keep it near the window where it can get a better signal.
You need to post a lot more details.
Are you on wifi or mobile data? Are you 3G or 4G area? How strong is your 3G/4G signal?
Have you dug into the battery use screens to see what's up?
Grab Spare Parts from the Market if your ROM doesn't have it and look into it's battery statistics...things like wake-locks will really kill the phone.

I've done this countless times to no avail. I'm going to flash Humble 1.25 again in a bit, but it definitely didn't fix the battery issue earlier today when I flashed it. Yes I wiped battery stats. Yes the battery was at 100%.
I'm going to try the ridiculous procedure laid out in this thread - http://forum.xda-developers.com/showthread.php?t=1152088

About same. No huge difference. I have a spare so I don't worry too much about it.

but is there any kernal out that support OC and undervolting? i cant seem to get SETCPU to work.
Technically Gingerbread manages everything better than Froyo and is better for battery life but because of all the ROM's and kernels available to us it's really a toss-up. I personally run Gummycharged Gingerbread because it is ridiculously fast, supports everything, and is great on battery. On a previous Gummycharged GB I was able to pull 2 days on a single charge with light-normal usage; like doing everything except playing games.

excellent life for me on Gummy GB, i get a full day on average depending on what I do though let me clarify a 'day' for me is about 16+ hours from when I get up till I get home and/or go to sleep... either way I think even with OC/UV on froyo I do better on GB but I always end up back on froyo for the themes lol
I've had better battery life on GB than on Froyo. It's anecdotal, but it's what I've observed. On top of that, Juice Defender works on GB, so you can make the battery that much better. With JD Ultimate with some aggressive settings and careful use, I could pull a day and a half out of the battery.

Glad to hear you make the differentiation and say JD works on GB... I run a rooted Froyo and tried JD last week. The data radio would not come back on when I brought the phone out of sleep state. Had to re-boot to get data back.

You're right that it does not work on Froyo. There's a bug tracker on the Latedroid website about it. They said last week that it would never work with Charge on Froyo due to a "terrible bug" as they put it. I've tried different combos of ROM and radio on the phone and the problem has nothing to do with the radio and everything to do with the Charge Froyo Touchwiz implementation.

You couldn't have failed anymore in this statement. For a lot of reasons. First of all, users that experience major battery issues with Gingerbread fail at flashing or calibrating the battery. Second of all, you're comparing it to a completely different phone! That isn't even a Charge! How can you even put that on our forums? Troll elsewhere.

I have tried a few EE4 & a few GB ROMs & I don't see much difference in battery life myself.
GB is certainly not WORSE than FROYO & may be slightly better. The difference is really negligible however, all ROMs get basically the same battery life - it is the kernel that can make a difference & even then it isn't all that much.
~John
And honestly it depends on your usage, if i just check for text messages once or twice an hour for the day, from 7AM - 5PM, i can have 44% Battery life left.
If i use some web browsing, and am texting every 30 mins or so, i'll be down to 20% Battery by 5PM.
If im watching youtube vids and using 4G, i'll be barely getting by at like 5% battery by 5PM.
I've tried danalo's HumbleComb ROMs, both -Froyo and -Gingerbread based. I believe he used IMoseyON's kernels on both ROMs.
I've battery tested both (battery consumption while fully configured and sitting idle - email and other minor background bandwidth consumers), and the battery drain was basically identical between the ROMs.
I saw a static drain of 2%/hour on both ROMs, which would be almost 2 days of battery life if the phone sat idle with minor background consumption.
With moderate use, I can easily make a full day on either HumbleComb ROM.
danalo's ROMs are pretty darned fast, to boot - Quadrant scores of 2040 on my HC4 GB loaded phone (Note: The Quadrant scores were faster before all my stuff was loaded on the phone).
And, danalo's HC4 GB ROM is pretty darned fast to boot, too - slightly under a minute (The -Froyo based ROMs were closer to 2 minutes).
Cheers,

I have updated to the official ICS (AT&T) and now I'm no longer getting much battery life. I had some issues with the update, so I wiped my phone and I have little to no apps.
I used to get 10+ hours of battery life, and now I don't even get 8 idle hours (so now it doesn't even last the work day). I checked Battery Usage after it was down to 20% and cell standby took up 90% of battery life.
I used to run JuiceDefender, but I reinstalled it on ICS.
Why have I lost so much battery life; how can I fix this?

I have noticed the same thing on the stock ICS. Also noticed very slow charge times using USB (possibly true with A/C charging but I am normally asleep when I charge with A/C).
Is this just caused by the bloat that they put in? I want to flash a custom ROM just for battery life at this point.

Instigator's kernel is for AOSP (CM9/AOKP) so for ICS based official or roms you will need a different one such as mohan's kernel:

As for battery loss, there are some cases where if the flash wasnt done with 100% battery it could be reading the battery wrong and some people have had success with recalibrating their battery (look up battery calibration on play store). Now it was said that it really doesnt do anything for battery improvements and was just for stats use or whatever but for some people it helped their devices read the right battery stats.
Couple questions;
Does rooting your phone = more drain on the batte? Seems like I got better battery life when it was bone stock.
Does themeing help with draining the battery?
Sorry if these are stupid questions but it seems like I had better battery life out the box on my phone. I'm running SYnergy r60 and it's themed with Eye Candy. I have been checking the things running in the background and it's doesn't seen like anything more is running then in stock. I have WiFi turned on at and work and get pretty good service in the building. But again it still seemed better stock.

If you concerned about battery life then you should try "Clean Rom & Clean kernel". They based on stock rom and provide good performance and very good on battery life.
Different roms will have different effects on battery.
I am stock, stock recovery, bootloader still locked - but rooted.
As far as rooting alone, i'm seeing no difference in battery life.
Once you go flashing things, it's a whole new ballgame.
The problem with flashing roms/kernels is that you are continuously doing it. So every couple days you flash a new rom, or kernel, or new mod. So your phone never really has time to collaborate and settle in. Technically you're suppose to give a kernel and rom a couple days before judging battery. But we rarely do that. Plus files can get left behind from previous dirty flashes that can affect battery life. There's just a lot more ways that battery life can take a hit when flashing roms/kernels, but it can also get you significantly better battery life.

Rooting itself makes no difference. Certain services and programs that require root could drain more battery but that is obviously optional.

It could hurt or help it but only to a small degree. Black uses the least power to display and white uses the most. Overall, it isn't something to stress over too much.

Thanks for the info. I didn't think it would be a huge drain but wasn't sure.
Not sure if it's coincidence, but I reflashed r60 but didn't reflash Eye Candy and it seems the battery is doing much better.
Hi, so I recently got an Infuse from someone that is still on Froyo and I figure I might as well upgrade to a custom rom.
Since I care about battery life the most, I figure I would ask which version of Android provides the best battery life for the Samsung Infuse: Gingerbread or Ice Cream Sandwich.
I probably won't be running apps that fetch/push for data a whole lot, which obviously helps the battery life. But I thought I'd ask to get someone's opinion on this specific phone and a comparison between Gingerbread vs ICS before picking a rom.
And the winner is... Gingerbread!

Gingerbread is a better battery saver. Although i get decent battery on ics and jellybean. I know i perfer all that ics/jb has to offer in features over having battery life. But for what your asking id suggest AEON or the stock gb. Aeon is very stable and has some cool extras without much battery drain

I have never payed that much attention to battery life..

Sent from my sweet & buttery Infuse
the more recent ics and jelly bean kernels get great battery life due to fixed bt and wifi drivers (the wifi driver and binary were taken from another device from what i understand) and more stable cpu clock code than it had initially. not too much more than stock but i have to say it is better for me. but i guess it all depends on usage. one may have better standby vs awake battery life or something. the available kernels have been this way for atleast a month. when we start to see more kernels with undervolt it should get better yet.
I'm using CM10 8/23 and my battery life is good.
One of the best I even made a snapshot (can't upload right now): 51% left after 12 hours 46 minutes.
That's why I'm in a dilemma between jelly bean and gingerbread. I do appreciate JB a lot, way better functions. But still the battery life and compatibility are big issues. I can get 2 days under gb but only less than 12 hours in JB, that's a big issue.
I have been getting great battery life with the latest JB ROMs I have been using. Pretty much on par with the GB ROMs I used.

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

i do notice battery drain in some areas. but not others. some people seem to think certain modems are effecting the cell standby drain, not sure myself. but there are many compatible modem.bins to try from att and t-mobile(t959v)
Just an update: wifi didn't help much.

I've been playing around a bit with different gb kernels, odex and deodex.
I found the drain issue much less on stock uclb3 kernel and rfs file system.
Almost all drain were associated with being on wifi...wakelocks and something else kills the battery.
If I have wifi off, there is usually not any issue.
You may have to play around a bit to see. My experience on cm9 and cm10 has been limited. I have noted several users noticing drain on cm9 and cm10 as well.
To avoid drain:
1. Use it to the max and constantly.
2. Leave the phone on airplane mode when not in use.
3. Turn off data (wifi and mobile data) and background data when not in use. I use this last mode.
Thanks for the tips man :good:
Airplane mode of course makes batt life better (disabling data doesn't), but when I start having to make sacrifices I didn't have to on GB it becomes a problem for me. Why should I jump through hoops and gimp my convenience for battery life that still isn't even as good as GB?
Instead of that i'd rather try to find the root cause of the problem. Doing so then allows us to help others that may have the same problem.
It definitely is an issue with the radio (or rather CM code overlooking something concerning the radio). What exactly, i'm not too sure. I've tried different modems as well, UCLB3 on JB was awful for battery life, UCKL2 and UXKG3 are slightly better but still not that great.
I don't want to complain about these things, I always try to research first, but damn....i'm stumped.

Yeah, I agree with you there. The techniques I use is pretty simple. Pose the hypothesis. Start with a full deck and slowly eliminate or start minimal and add.
ex: flash jb without gapps; without microSd. try different modem; try a different kernel. different kernel from different build.
have to use it for a few days to find out.
do the same for cm9.
add gapps...
add microsd
etc..
at some point, you will find out contributing factors.
There are a few battery thread that may be helpful if you havent looked:

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...

This is true, and you can save battery life w/ customization and now Scott is up to JB being one of the best battery life roms I've run
or just turn down your screen brightness
