Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you

I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.

Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..

I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...

Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.

I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.

Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours

neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.

Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.

Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.

you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.

My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

Battery on Bamf 1.8 stripped

So, I just flashed this ROM yesterday.
Full charge over night took phone off charger around 7ish this morning. Did a quick 30 minute run/walk workout w/the Cardio Trainer recording (tracking w/GPS), all while listening to the FM radio. I have had two phone calls totaling about about 7.5 minutes. Maybe 35 text messages in and out. I'm in a strong 4G area, I do not have my phone set to automatically get email. I just turned off the facebook hourly update, just noticed I hadn't done that yet ..... my phone is already barking at me that I need to plug it in.
With the exception of my run and listening to the radio this morning I really haven't done much .... I downloaded a couple of apps and tweaked them, but seriously 3.5 hours of battery before it's telling me less than 10%.
Any suggestions?
I did not clear the battery stats, in my past experiences that really didn't do anything to help (but that was w/the Eris).
I'd love to have GREAT battery life that everybody talks about. Anybody using this ROM have stupendous battery time? Not sure what has sucked the life out of this.
Thanks

I'd say it's the GPS that killed you.

same thing for me on bamf gb 2.1. i was at 20% after 5 hours of use

IDK about that, I've gone out for the same 30 minute walk/run w/the battery on yellow (on stock rooted) and the radio going and it hasn't killed it. I think maybe it's part of it, but IDK it's all of it.
I've put the phone on strict 3G, going to totally KILL it tonite and turn it off while charging.

Have you tried recalibrating your battery since installing Bamf 1.8 stripped? Maybe it's not a problem with the ROM, but with the battery calibration.
Sometime at night shutdown your phone and then hold volume down and power to boot up HTC's nice bright white bootloader. Leave it alone until it dies (the phone cannot die properly while running Android, since Android will shutdown the phone when it thinks the battery is low, rather than when the battery IS ACTUALLY low). Plug in the power cord after it dies, but leave the phone turned off. It should take a few minutes for the orange light to turn on because it's so dead. Leave it alone until the green light is showing in the morning. Then start it up. This will get the proper 0% and 100% points for your battery stats. Also check what apps are killing your battery. I was having a problem with Google Maps for a while until I cleared data on it.

I have a similar problem. I will take it off the charger and after a few minutes it will be down around 97%. No big deal. I will set it down and walk away for at most 15-20 minutes and come back and it will be on like 80%.
After that though the battery life stabilizes and I get 12+ hours with moderate use

Running AOSP CM7. I have had my phone off charge since sometime around 6 am ET this morning and at 50% now at 11 pm. This has kept me kept me from getting an extended battery. You should try it.

How is the stability on this? Is it good enough for a daily ROM? (not that it's not "good", I know their work rocks) - I don't know if I want a "testing" phase ROM. Hope that makes sense?

3g to 4g handoff is the main complaint I hear, but I'm not in 4g area. Have driven through a 4g area and it seemed fine to me. Put it this way, this has been my daily driver for over a month now. And GPS gets near instant lock btw. I don't want to hijack the thread so I will just say that I NEED my phone to work and if too many bugs were present I wouldn't be running it.

Your display is only at 5% of total usage... You hardly used your phone. Of course its going to last for 16 hours when it just sits there

tell me your secrets
i just flashed 1.8 remix i get like 9-10hrs of battery with little to medium use

as ive said i must of lucked out with a solid battery as ive never had the horrid battery life most claim on the net. even with 4g on all the time i get well over 10-12hrs with medium/heavy usage.
a suggestion for a solid kernel is the 3.3.7 lean kernel, don't overclock too high either. i think that's why alot of people have the crap battery life and random reboots.
if you live in an area that doesn't get good 4g coverage id switch to 3g only mode if i were you.

appreciate the info, don't think you're hijacking at all
I've totally turned off my 4G (even though my home area is FULL 4G) and my battery life seems to have improved. I still have to do the recalibration thing, I keep forgetting.

How is the lean kernel with 1.8 stripped? Any compatibility issues?

ditto I would like to know this as well.
- is this different than what is included in the bamf toolkit?

im using bamf 1.6 and i get 20-24 hours batt life
brightness always on 25%, unless outside then i bump it up and then turn it down when im done. lower than 25% at night when the lights are out and im just watching tv
background data and auto sync both off
moblie data off
use wifi whenever possible
switch to 3g only when youre not in a 4g area and you need to use the internet

I get incredible good battery life with the Das BAMF 1.8.6 NTE so I would expect the same out of Stripped. I would consider another kernel, I am very happy with utkanos http://forum.xda-developers.com/showthread.php?t=1025199 Are you on MR2's radio or MR2.5? 2.5 seems to do much better with GPS.

What is using up your battery because if it is the Cell Standby or Phone idle I have a fix for you. I had always had great battery life until last week when it started draining as you describe in your post. I tried everything to get back to where I was but was not successful. I ended up pulling out the 4G card and reinserting it. I was instructed to do this by a Verizon tech. I though he was wasting my time but it fixed my battery issue and I am getting great battery life on BAMF 2.1 and also BAMF 1.86

That's interesting, I wonder what that would do and why it would work? These phones do like to keep us on our toes, eh?
I've made the switch to CM as of yesterday so I'll be playing around w/that for a while.

Battery life is better on sense than aosp.

Is it just me or do i get better battery life on sense froyo roms then i do on aosp gingerbread roms. On aosp i lose anywhere from 7-10% battery per hour, standard use, and on sense i lose 3-7% per hour, standard use. I am on Bamf Remix 1.8.6 with the desense script, and the aosp roms i tried were cm7 and omfgb. I really wish i got good battery life on aosp, it is so much smoother and quicker, but I need my battery to last as ling as possible. Am i alone here or what?

You're going to get better battery life on Froyo over Gingerbread.
What are your setting though, I go all day with pretty good usage (browser/text/facebook/youtube/Music) and I'm always good to go.
I'm running CM7 stock kernel. Display at 40%, 4g disabled when not needed, Wifi disabled when not home and I can't really say I have any complaints.

I thought always thought that aosp GB was supposed to have better battery life.....
I had imoseyon lean kernel on battsaver and ondemandX, wifi off because I'm almost never home, 4g on, all the same settings I run on BAMF. Display at 25% usually unless the sun is blaring.

just curious did you wipe batt stats do a full drain and recharge and see what you got after that?

No, I'm guilty of not doing that. I guess I should try that shouldn't I?

I found the best battery life on Liquid ROM, which is GB.

Can't hurt. I wipe batt stats every time I flash a rom.

Although that's an obvious solution. There's more he can try before he goes to spend the money for an extra battery. I honestly don't see a need for an extended battery and I play around on my phone all day. When I get in the car charge it. When Im at home on the pc charge it.

I definitely get better battery life on Froyo sense than aosp gb. I, personal, think I get the best battery life on a stock version. I'm currently running the rooted OTA and the OTA MR2 radio and am getting great battery life (4g off, don't have it in my area till the end of the month).
I wish CM7 got good battery life. I like it better than any ROM I've tried, but can't get over the battery drain. It's ok though, I like Sense a lot too.
But you know what they say: To each his own.

to each his own is right
But on the same platform (froyo vs gb) i just dont think you are going to get tremndous variations in battery life. There may be an outlier rom that uses it quickly by most of the roms are in the same ballpark. i think we are talking about squeaking out an extra 20-30 mins which is not nothing but 8+ hours of a battery charge i would be more inclined to go with whatever rom i like best. When GB is released for real, then we may see some improvements across the board.

I have to agree. CM7 has been way better than any other rom i've tried.

CM7 with Kang Bang does best on mine, but you can't compare sense froyo to aosp GB. That's too many different factors. That's a different framework, different kernel structure, different ROM. How do you know what the culprit is?

I'm running BAMF 1.8.6 as well on standard battery.
I just charge at night, take the phone to the car or motorcycle for commute and place on charger. When at work, I have another USB charger with micro USB cable. Charge when at desk. Reverse procedure for drive home.
Battery is great when only off the charger for ~4 hours per day. :-|

It seems that sense battery life is better. I've been on cm7 for a couple weeks now and my battery will be nearly dead by this time every day. So I'm getting 5 to 6 hourz max with cm7. I'm on gingertheory now with dream kernel and setcpu running a few profiles, battery life is at 70%. May have been using it a little less today but still that's a big difference.
Sent from my ADR6400L using Tapatalk

Getting the 2750mah extended was the best investment you can make into this phone, hands down. If your phone goes naked, then the difference in thickness is not that bad. In fact I love the new added thickness. It keeps my camera lens off the surface when I put it down flat. Not to mention it adds a certain heftyness that just exudes quality.
Sadly though I got an unlucky battery cover which creeks if you squeeze just a smidge on the sides
Other than that, man is it great. I can go about 48 hours without charging on CM7.1. At the end of the 48 hours, my screen would have been on for roughly 5-6 hours. That means nearly 3 hours of screen on time a day. If you sleep for 8 hours a day, that leaves 16 hours of awake time. 3/16 means nearly 20% of my time awake was spent looking at my phone. Hardly minimum usage, and if its not considered heavy then I fear for future generations. Screw these kids today 12 years old with a smartphone lol. I didn't get my first cellphone till I was a senior in highschool (2004) and even then, it was a crumby flipphone just for the sake of making calls and in case I was in trouble.

so is Gingerbread or Froyo better for battery life on the charge?

Which is better for the charge?

About same. No huge difference. I have a spare so I don't worry too much about it.
Sent from my Gummy Charged GBE 2.0

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.

someone had already asked about this and it was confirmed that battery is diff better on froyo they actual took a poll and everything and about 85% of users was having major battery issues on gingerbread.

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.

Nothing could be further from the truth. Battery life on GB is much better as well overall performance .

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,

so what is the differnce in FroYo and GB?

Battery Life on Infuse: Gingerbread vs Ice Cream Sandwich

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

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

Honestly, I don't even remember by now
I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need
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.

Yup, it's all been the same since ICS, I absolutely cannot get acceptable battery life, no matter what i do.

are you getting AOS drain while on wifi?
you may consider a factory reset and sdcard format
when you reinstall, decline all google locations and backup services.

I have done a factory reset, i formatted my sd card not too long ago (I also suspected this)
I also make sure google locations is disabled, never keep backup enabled (i did once by mistake and the auto restore nearly killed all my monthly data)
I am going to toggle wifi tonight and set a marker in BBS, i'll check the drain overnight (I did this a while ago and it did improve standby drain somewhat, but I am going to try it again)

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:

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
