I was wondering how I could extend that battery life on my DINC? Any suggestions and tips would be great.
Ah yes, the battery issue. One I am all too familiar with.
Easy:
For whatever reason our phones charge to 90% and stop there. To correct this, you can either charge while the phone is off or do what we call a bump charge. Bump charging involves charging the phone to "full" while its on (the light should be green) and then turning it off while still plugged in. The light will then change to orange again for 30+ minutes and then green again. You will then Really be fully charged.
Also make sure you have GPS and Bluetooth off when you aren't using them. This will help a ton.
There is an option in Settings - Wireless & networks - mobile networks - called "enable always on mobile data". Unchecking this will drastically help save while the phone is asleep on the 3g network. However, doing this will affect how often you receive updates to chats and sync items when the phone is sleeping. To me it isn't a big deal since if I'm not using the phone why should it be working, but everyone is different!
Finally, a rogue app might be nomming away at your battery. An app from the market called System Panel will monitor how much battery each app is eating. Its free initially but if you want it to monitor over time in the background it does cost. However it is definitely worth it since its a great app and useful for any android owner.
Intermediate (has cost):
Evo batteries fit in our phones! The fit is a little tight but it works just fine. Our stock batteries have 1300mah of capacity which is a bit on the low side. The evo battery has 1500, so it's an hour or so better. You can buy them cheap off ebay (OEM Evo Battery) for around $15.
Conversely, there is the official extended capacity battery for our incredibles with a massive 2150mah. The trade off is that it adds bulk to your phone and costs a lot (around $50). There is the third party seidio battery which adds even more capacity (3500) but adds even more bulk.
Advanced:
Are you rooted? There are kernels out there that are undervolted like Hydra kernel, adrynalyne's undervolted and kingklick's voltage scaling kernel. Everyone has differing experiences with them so there's not a solid "best" so to speak. You can flash these kernels using the clockworkmod recovery. This will all be nonsensical if you're not into the Modding scene.
Also if rooted, you can underclock the processor which, depending on the kernel, can help drastically save battery. You can set profiles to have the cpu work at a minimum speed while the screen is off. Kingklick doesn't advise using setcpu with his kernels and it straight up wont work with hydra's, but it can do wonders on any others.
--
Depending on your activity, you should expect 4-5 hours of 3g awake usage and around 5-6 if you're mostly on wifi using the stock battery. 3g can be a battery drain if you're in an are with inadequate service.
Hope this helps!

turning off gps doesn't matter all that much. GPS isn't called upon unless you have an app using it. I have mine on most of the day (for tasker profiles) and have no issue.
Use WiFi when available, its quicker than 3g and takes less battery.
download setCPU (from xda) and make a profile for screen off max/min = 400/245 or something like that.
i have 'always on data' checked, no issues for me
kernels help a ton, kk#5 is a beast.
I'm running uncommon sense, kk#5 and the above settings. I'm on 20 hours unplugged with 35% less, standard usage. -- not bump charged, charged while on to 100%
isn't the system panel app like a task killer? and from what i've read task killers are pretty pointless with froyo......however i have noticed that my phone is constantly running with about 140mb of ram free, i don't know if this is usual or if something is wrong?? i just got my Dinc so i'm new to all the tweeks and tricks, i do have mine rooted though. i'm not that up on changing roms and kernals though so i'm just trying to find out what all i can do to help my battery without having to buy a bigger one. any help would be greatly appreciated!!
If you are rooted and aren't comfortable with flashing ROMs and kernels, look at setcpu that was mentioned before, and search for instructions to remove the stock apps that always startup on their own in the background. Unless you actually use them, then you can't really do that obviously. I don't have any times on how long it lasted before and how long it last now but I do know its improved. I have mine at a processor clock speed of 500mhz and I don't see much lag time unless I'm really running a lot of things. I'm on WiFi listening to Pandora and I'm not experiencing keyboard lag while typing this.

no...the max it'll run is 1.19 ghz. worst that will happen is a bootloop which can be fixed through nandroid.
Just increment a little at a time. I usually run mine at 1.075 ghz w/ on demand.
screen off profile max/min - 450/245
I use JuiceDefender on my Incredible and believe it or not it really works. It's turns off your data while the phone is on sleep mode so no battery is being drained. I get at least 5 hours extra battery life. You also get other features that come along with it so just give it a try It's free!

Yes system panel CAN be a task killer but I do not suggest using it as such. Instead, it does a great job monitoring how much CPU each app uses so you can take educated action.

1. If you use location based services and have GPS on, it will use the GPS module quite a bit. This is certainly a battery drain.
2. If you dont have any issues with always on mobile data then you must be in an area with good coverage. For me if its left on it drains my battery quite a bit because I'm in a flaky coverage area.
Everyone's phone is different though. Finding what works and what doesn't is the first step to perfection. I just installed the new skyraider sense and my battery life has been ultra fantastic. It works great for me, but I know others dont have that success.

First off Happy Thanksgiving to those who celebrate it.
Ok so i am wondering a couple things. I have an HD2 with one of Mdeejay's blends on it. I use launcher pro so looks aren't really gonna change too much. currently I am having huge battery drain. I'll charge over night and cant seem to get past 80%
1. Which Rom is the best on battery power?
2. Are there any underlying things in WINMO that maybe I should turn off before starting android?
3. Are there any underlying things in my android build that I can turn off?
4. My task killer seems to always get full even when I don't start certain apps, is there anything I can do about this?
Thanks to all that help.

1. Some roms may cause problems, but all compatible ones shouldn't have influence on battery life. It's just hit & miss, try the one MDJ suggests. (probably mentioned in his thread)
2. There are some tweaks available yes, I personally doubt they work though. I get good standby battery life w/o even having looked at those tweaks. Just search for registry tweaks on this forum.
3. You can always turn off mobile data, sync, 3G (and obviously wifi, bluetooth, and low screen brightness). Install setCPU to underclock your processor (again, there's a lot of informative threads on this already)
4. Uninstall your task killer and never think about it again. They only do evil on Android. Having apps in your RAM memory is now actually a good thing, as opposed to windows. (yet again, a lot on this can be found through search.)
About the max of 80%: your battery isn't calibrated well. Either search for batterystats.bin on this forum and you'll find a guide on how to recalibrate, or reinstall your android build with a 100%, completely charged battery. Check the percentage in WinMo, and then leave it turned off for half an hour to make sure it's reaaally fully charged.
Completely agree with the above, with the exception of SetCPU. You're far better off with a recent kernel (I'm having great success with MDJ S6.1) setcpu is pretty much redundant now unless all you're interested in is melting your processor with ridiculous overclocks and pointless benchmark scores. ("Oh look I get three more points in quadrant than you but my phone reboots every 15 seconds")
After I performed my battery calibration I get two days moderate use out of my phone with no problems.
what if I were to charge to the full 80% then re-flash wouldn't that make it so the battery is 100%... also if i can only get 80% I would think that a flash at 80 would tell my phone it was 100 when in actuality it was 80. Maybe I'm confused about the whole battery conditioning issue.

You might want to read my post again, I suggested to install setCPU to underclock the CPU, to improve battery life. I don't quite see the point in overclocking either.
I'm looking for a ROM which can make my device hit at least 24 hours with light/moderate use. I know it's based on how the much the user interacts with the phone, signal strength, etc but there has to be a ROM which made your battery life amazing! I'm currently hitting about 12-14 hours with light to moderate use. I've seen people that use it the same amount and get nearly 2 days, how can I achieve this? I read somewhere that Pershoots kernel does well with extending battery life.
I'm currently on CM7 with the stock cm kernel.
Thanks for any helpful posts!
Okay so in my experience to get 'good" battery life with a g2 you need to turn off your push updates, stay off of data as much as possible, and only hook into wifi when you need it. Make sure your screen is on for no longer than 30 seconds, turn down your brightness, and set some profiles under setcpu to downclock you after you get to sub X battery life. Just make sure to increase the priority the lower your battery life goes.
The best and most consistent battery life figure I've gotten is 42-48 hr by generally not being a complete dickwad. If you flash a rom and have to download all your apps again it is going to suck you dry. I ran Cm6.1.1 with preshoots kernel for a goodly while and have pulled the same speed/battery life as I do on Virtuous with Advanced Kernel. It's taken a couple days for it to settle in but yeah, you're looking at 42ish with moderate net usage, full signal, and darn near constant texting.
Edit: Let me clarify. As your power goes down you should downclock in 5% increments. For every 5% less battery power you have, you need to increase the priority of that profile by 5%. Make a profile that is 100% priority but downclocks your cpu to 350ish max and 200ish min. Also something to keep in mind is that every piece of hardware is different. Some people can report fantastic life on the same kernel and OS. Just one of those weird machine god things.

I can get a day and a half with team villian sense ginger. The one before 3.0 best battery life i have seen yet. This is a 1.5days with constant OC no screen profiles or any kind of battery saving profiles. I would say im a slighty less then heavy user. Wifi always runs and i use gps for about an hour depending where im going. Now i normally charge her up every night but i have forgotten on ocasion and made it till i got home from work the next day.

+1 on villan rom, i set an off screen OC to 300MHZ and an on screen to 1.5Ghz, and i get 20+ hours out of it with mild data. wifi off unless im home and location always turned off unless i need it.
Might give that villian rom a try, is there a specific kernel I should use? Or should I just use the one that's already on the villian rom?
Sent from my HTC Vision using XDA App
just download from the current thread, the 1.5 version, it has an kernel that OC's to 1.5GHZ and works well.
i would download as is, and if you like, play with the kernel later on if you really want to.
Or if you like sense get sense ginger. Im not sure how you can get the older version but you could try the new one.

He is right, but lots of us has been through several ROMs and I can say that from the look of it all the ROMs use lots of battery life due to all the running processes. If you end up finding a ROM that supports your needs post it and let everyone know. Hope I helped
I've been researching extensively how to improve my battery life on my Android phones and I believe I've found an amazing setup for the Atrix. My phone has been disconnected for 3:15 and I'm at 91% right now with moderate use. It used to burn about 5% an hour before with NO use. Yesterday, it lasted 14 hours and I still had 20% left when I went to bed.
Aura 1.1.3 Debloat #7 ROM
This ROM seems to be the lightest one I've tested. It's only 150 MB and very fast.
SetCPU
I set up a profile to underclock the processor all the way to 216 MHz when the screen is off. The processor is running at 1.1 GHz max. I haven't tested underclocking it to 1 GHz or 900 MHz. I'm sure that would improve the battery life even further and not have a huge impact on performance.
Battery mode (Android settings)
Obviously, it's on maximum battery saver.
General settings
I set the screen timeout to 30 seconds. Maybe 15 seconds is too short for you as it is for me, but that would save some more juice.
Every other battery-killing feature is on, like wifi, GPS and sync. I don't use task killers anymore and found out that my battery life actually improved a lot after I ditched Advanced Task Killer.
I just wanted to share this with the community. I hope it helps you. Any suggestions to improve it even further are very welcome.
Yeah task killers are pretty much useless, watchdog is a wonderful alternative.

Interesting and thanks for sharing, but...
I can get almost the same results by using any other ROM without SetCPU and just using Max Battery Savings but I'm not interested on that setup because I need to have PUSH email all day.
Maximum Battery Savings makes push emails useless, and for a device that's supposed to be "connected" push mail is a must (at least for me).
Unfortunately, push mail is what kills batteries, specially on 3G/4G.

My phone was maximum battery savings one time for some reason. I didn't do it. But for some reason, it was seriously draininng my battery bad. I think i was on 2.2/froyo before i unlocked so i don't know if that had anything to do with it. I do know, i haven't had reason to try it intentionally since my battery is great overall. It does help since atnt turned up the juice on the 3g and called it 4g reception has been very satisfactory lately helping power consumption by not having to look for a signal as often.

Exactly! When the phone switches back and forth 2G and 3G/4G it drains a lot of power. So it too depends on the zone we are in at the moment and that's one of the reason we see a lot of different results among users. Of course, phone and app/game/internet usage style also counts.

I think a lot of people don't realize that terrible reception can account for terrible battery. Often we don't get that feedback when people are whining about battery. Also, lots of the people whining about battery play lots of games, and some of those games that put the gpu through it paces suck up juice faster, but the user is not realistic about that either and expects battery life of a phone that is used lightly.

Yay for undervolting
not "killing" aka "ending" or possibly more familiar "closing" your running apps.. that's like, like if you log into your windows box and you don't have the "X" buttons on the window caption bar.. you just leave everything that you run running until you shutdown..
before you even try to retort, obviously there are exceptions. in windows explorer.exe runs endlessly until you shutdown. on your android device that's the equivalent of your preferred launcher.
what else.. msn? the equivalent of your favorite sms app. facebook and notifications? similar to that browser you keep open with 5 or 6 tabs swiftly consuming your precious processor.
i'm not sure an argument even exists. "task killers" has "killers" in the name which naturally has negative connotations. call it a task manager. windows has a task manager.
other than that nice tips
I am stock everything.. even launcher
3hrs 14min screen on time
~12ish hours off the charger
still says 50% battery. which means 50%-59% on motoblur
pretty darn good eh?
Don't understand the point you were trying to make. Are you saying killers/manager is worthwhile or were you trying make a worthless point about the names?
Anyways task managers are worthless. A good comparison to make are mid/high end laptops and their ram. On a forum I frequent, users were comparing their battery runtime with similar setups. Some were getting extra ~hour or so than others who couldn't figure out why they were getting shafted on battery. Some people don't realize that 4 dimms of ram consume twice the power of 2 dimms of ram no matter the gb of x amount of ram. Thus its better to have 2 dimms of 4gb each than it is 4 dimms of 2gb. The ram consumes power whether you use it or not if it is connected. The 1gb of ram in the atrix consumes the same amount of juice whether its holding 300 mb of data or 800 mb of data. Whether the cpu is computing with something active or not in the ram is what's relevant. Task managers only help when you have a rogue app. Id rather uninstall it then deal with a poorly written app.

Although that may be true for windows computers it its not with Linux which Android is based on. I know that there are virtual machines and all that jazz for the apps but the core system is all Linux and it's even optimized for battery life so when you press the home button yeah that is still running in the background but if you ever need to use that ram it either clears that app from the ram or (based on the app) kills its altogether. And like someone else said ram uses the same amount of power weather it's being used or not.
Also if you're using well written apps then they shouldn't be using any CPU in the background.
If there is some app that's hogging CPU in the background then you need to just uninstall it. Task killers especially auto task killers are actually using a lot of your CPU constantly checking for apps that are using too much ram but Android already does that automatically.
tl;dr
Linux can manage its own ram without you and for the love of God, stop using task killers they're making everything worse.
i was defending their usefulness in general not so much their effectiveness in battery preservation. probably the wrong thread. if any its minimal.
i'm talking about active task management tho. when i'm done browsing the web and want to fire up pewpew for some old school polygonal destruction i kill the browser entirely. i guess its really based on the type of user you are whether or not benefit is to be had. some people are active while others are standby

Sure, it depends on how you use the phone and the strength of the signal you're getting in your area. Would you guys just turn data off in bad signal areas to save battery? How would you handle that?
This is what happened. My battery is doing amazing. I changed the battery mode to Performance during the day and I still have 65% after 12 hours. Not bad. It's about 2.9% an hour. The display was used for a total of 2 hours and 10 minutes.
Battery life posts are useless unless we have some kind of standards during testing.
Like setup your system and then a 15min phone call, 1 hour of video/ ect.. same call.. same video same ect .. ran on each battery setup will give a truer idea on what saves battery the best.
This whole .. it was off charger for 5.33 hours and I used it alot and its at xx% doesn't hardly mean anything.. how much use is alot? How much is little?
Need some kind of same standard test that can be run..
nice to know

Mostly its not about the ROMs you use, but the Kernel or Baseband (Radio) firmware.
At least for me it's been much better than with the original ROM.
Also you must take into consideration other factors like type of use, voice/data signal quality on your area, and many other factors.

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

1. CM9, although i think aokp does better.

-CM9 still seems cleaner, but AOKP seems better.
ÜBER™ said:
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.

3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.
Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.

Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
