My battery life is horrible, any suggestions?

I have been thinking about flashing a rom or something to make my phone get a better battery life but I want people's opinions on what apps to user and potentially what rom I should use. I've never flashed a rom before either but I am rooted using juice defender and set cpu.

Have you tried cpu tuner? It gives you more options for profiles and better cpu governor control.

Haven't tried that yet. I followed someones picture on how to get setcpu setup right.

My current setup is Myn's 2.2 RLS 4 with Kings #11, no CPU tweaks, autokillers, or memory tweaks, with Watchdog and JuiceDefender, and I seem to be getting amazing battery life. I had to try out pretty much every kernel in the book before I setteled with this one though.

how many batteries do you have?
you many have to recalibrate your battery stats.
if you have 2 batteries and an external charger:
charge the OEM battery in the external charger, those usually charge SLOWER than the AC adapter which is better for the battery
when the OEM is fully charged, turn off the phone and insert the OEM battery
boot into recovery and WIPE your battery stats
reboot the phone
depending on your ROM and kernel, you should easily get at least 2 days run time per charge.
After this, don't use a 2nd battery anymore, Android sucks at recalibrating the battery stats every time you swap batteries. Really a shame.

I agree with this.

Really cause I wiped my battery stats. But I'll follow that cause it sound like you know what you are talking about.

Party I did everything except I still have stock rom ana have never done a rom before. I'll see how long this lasts like this.

Turn off Mobile Data always on, go to Google Talk/settings, and uncheck automatically login, then log out.
Get rid of people/facebook/twitter widgets which constantly download pictures from your thousands of facebook friends/followees, or make those widget do updates at human intervals, like maybe once every 30min-1 hour.

I dontt have any facebook widgets out. I didn't even know my google talk was always signed in like that. mobile always on is off. After doing the battery stats wipe and using the OEM battery I am already at 93%. Maybe I should get a rom? I have juice defender running at 1.5x(maybe it's a problem?) And setcpu also.

I found that having set cpu and juice defender etc. didn't improve my battery life very significantly. Or I should say, significantly enough to justify slowing down the device on purpose to save battery life.
A good kernel (like netarchy's 4.2.1 cfs havs more) will help quite a bit with idle battery consumption, and somewhat with the active usage consumption. A rom would probably not change it much, but try something like Virusrom Airbourne (I had excellent battery life results with that one).
In the end however, you won't be able to get better results than approximately this:
1) ~1% battery drop in 1 hour of idle (screen off, 3g on) time.
2) ~0.5% battery drop in 1 minute of active usage time.
That's the hardware limit - a fully charged battery will afford about 100 hours of standby, or about 200 minutes of active usage time (less with cpu intensive games, which will heat and drain the battery more, of course).
There's one big battery drainer I haven't mentioned outside normal usage.
If your cellular signal is bad, the cellular radio tends to drain the battery in a BIG way.
In my office, I have pretty bad cellular reception. I actually have to force roaming and connect to a different provider if I want to save battery.
(In fact, I think I just dropped 8% in about an hour of basically standby, because the signal is 0-1 bar here).

You made a lot of nice points there. I'm in the basement so depending on the spot I'm in the 3g AND the 2g vary. By my bed is the worst but my wifi isn't cooperating with my phone. Always timing out yet keeping the connection. My battery was better with wifi when it worked cause it's in the same room. I'm thinking of uninstalling setcpu first cause juice defender increases it's percentage when battery sucking app is uninstalled and vice versa. I am thinking about flashing a rom but I hear so many problems with these roms so not sure.

I get about 2-3 days of run time after using this method. I used to have 2 batteries and swap but not anymore. If you want to use more than 1 battery, then make sure that both are the SAME BRAND and the SAME CAPACITY (mah).
Can we petition Android to automatically wipe battery stats every time the battery cover is removed? Or, even after reboot would be good.
Quite a few people in this thread getting 1, 2, 2+ days of run time:

That is your problem, you don't have signal so the phone is constantly searching for one. You will never have good batery life. You need better signal. Get an Airave

What's airave? And my signal only goes out by my bed.i don't sleep much.

LIES!! Battery stats don't get wiped, recalibrated, or other whimsical notions you have when swapping batteries.
I have three extended batteries, swap them out every 2 days and I don't get worse battery life with one battery over the other.
If your battery stats are being "recalibrated" when you swap your battery there is something wrong and it has nothing to do with android.

[Q] EXTREMELY horrible battery life

I've read on many reviews (Gizmodo, Engadget, CNet, etc) that the battery on the DInc is not that great, but mine is incredibly... bad. Examples:
I browse the web (mostly mobile websites with not many images, flash etc) for ~20 mins and battery life decreases by 20%
I leave the phone ON overnight without charging and it's at 2% in the morning. When I went to sleep it was at 60%
I turn the phone OFF overnight without charging and it dies (I couldn't turn it on, had to charge for 15 mins even to turn on). When I went to sleep it was at 30%
I've also heard both that ATK is useless and that it's a gift from God for battery life. I'm running the Pro version killing every 30min and it's not helping that much (maybe 30 mins)
Is my battery defective, or are other users also experiencing this bad of battery life? My DInc is SLCD, running UberZ RC1.2 with stock battery.

Im guessing you havent had your incredible for more than five months right? Considering htc didnt start making them until the late summer. Anyways I do know that desire z ports often use up quite a bit of battery in their displays. However considering you left it on overnight and it was nearly dead I dont think it was that. Something you can try is going in the advanced menu on clockwork mod and erasing battery stats. This seems more like a defective battery though. New batteries can be bought for fairly cheap and if you do decide to get a new one you can get them for pretty cheap. Touchpro 2 batteries supposedly work with the incredible as well

Make sure you turn off GPS, WiFi, Bluetooth, etc. when not in use.

Yeah, I've had it for about a month. I will reply after erasing battery stats and trying it out. I'm not sure that I would use a Touch Pro 2 battery - seems like too much of a risk. However, I have seen Evo Batteries on Amazon that supposedly work with the Dinc. Do they?
If it helps, I use widget locker, with: extended controls, fancy widget, nexus revamped (with a lot of spawns on slow) and 3 sliders.

I have, I barely use BT or GPS so they're almost always off. I only turn GPS on when I'm charging and I'm using location based apps. 3G is off at home and Wifi is off on the road / at school and when I'm not using the phone.

What you might want to try doing is uninstalling widget locker and charging your phone all the way up. If after uninstalling widget locker the drain is still significant it may be the battery. And from what I read, the evo battery works with the incredible, it just makes the back cover fit a bit more tight.

OK, I've wiped battery stats, though it's only been a few mins so I can't tell yet. I'll reply in a couple of days. Also, can I just disable WidgetLocker instead of uninstalling it?
I also have a silicone case that hooks on the front edges, will an Evo Innocell (with back cover) mess with that?

I dont think an evo back cover would work for the incredible as they are not the same dimensions.
And btw touchpro 2 battery will work with the incredible

Heres one for $5 if youre thinking about it.

I just moved to an Incredible from my Droid 1 and the battery life is horrible compared... I got it as a replacement for having so many issues with my Droid but the battery life is almost unusable I'm running CM 6.1 and I wiped my battery stats, drained the battery then let it charge overnight powered off and I still get really bad life... I think a lot of it may have to do with the stock 1300mAh battery compared to the Droid having 1500mAh but I'm not sure... I'm considering the 3500mAh sedio battery but $70 bucks is a bit steep atm

Thanks for the great find, though I was thinking about maybe one of those seidio 3500's. Though since it's so cheap, I'll probably buy it

I've seen one on amazon for ~$25. Not seidio though. Reviews were meh.
I don't think its the 1300 mah vs 1500 mah. That's less than 20% (so like 10 hrs vs 12 hrs).

Yes you probably can disable it just make sure it is definitely not running.

Don't run ATK. Android manages apps by itself. There's a whole lifehacker article on it.
Sounds like a run-away app.
Hmm, turn your screen off and let your phone sit for 5 mintues. Go into Settings > About Phone > Battery > Compare uptime vs awake. They should be AT LEAST 5 minutes apart.
If they're not, go to the market and install "Watchdog Task Manager" (<--this is NOT the same as ATK, again, lifehacker article on it) to monitor rouge apps.
Hope this helps!

My phone has been sitting and charging for ~2 hours, but up - awake = 5:12. Is it normal?
Great work, by the way.

There is no normal.
Up time is the elapsed time since you turned your phone on. (i.e. after the phone was completely off, not just screen off/sleep mode).
Awake time is suppose to only be the time your phone was actively being used (i.e. screen on).
So, Up time minus Awake time should equal the time your screen has been off, (i.e. asleep).
If Up time and Awake time are equal, and you've had the screen turned off (i.e. asleep) for part of that time, then you have some app that's staying active durning sleep mode.

1300 Mah battery is not acceptable for a phone of this caliber. There are alternative options for battery's. I use setcpu to underclock the proc and I've seen a dramatic increase in battery life.

I've been using Setcpu as well, with 998 mhz while charging, 245 when screen off, 245-520 when hot or <20%, and 245-850 otherwise.
Agreed about the battery, HTC and VW probably want to force you to spend more on extended batteries.
Too bad, otherwise it'd be a perfect phone.

HTC usually seems to skimp on the battery. It really hurts their reviews but I suppose they can save costs and assume people can always buy an aftermarket battery. I don't agree with it but it's their business.
Anyway, that does sound like abnormally bad battery life, but I have a question - are you in a poor service area? If so, the radio might be working extra hard to acquire a signal. Even when I had my dumb phone Samsung alias (which had decent dumbphone battery life) I would experience complete battery drain if I left it in my poor coverage basement overnight.
Also, when you're browsing the web and such do you use wifi or 3g? I notice that when I continuously surf with 3g the phone starts to get warm, especially in mid-poor coverage areas. When the phone gets hot the battery gets hot, and when the battery gets hot it drains much much quicker. Of course, high power usage generates more heat so I'm inclined to believe our 3g radio consumes way more battery than our wifi radio.
Over the months I've combatted poor battery life by doing the following:
1. Purchase aftermarket batteries. I've fallen into HTC's trap. I bought an evo battery which can last me of 6-7 hours of wifi awake time and 4-5 hours of 3g awake time. I also purchased the extended 2150 battery from Verizon which I can get up to 10 hours of wifi surfing and 5-6 hours of 3g surfing. Back when I was on stock 1300 I would get 3-4 hours wifi surfing and 2-3 hours 3g surfing.
2. Install an undervolted kernel, if you're into that sorta thing. One of the main reasons I'm able to obtain the numbers above is due to my kernel which undervolts the processor. I use adrynalyne's experimental undervolted kernel and it works without a hitch. I use it in conjunction with setcpu so I can have a screen off profile which underclocks the processor to 128-384MHz while I'm not using it. The only caveat to using this kernel is you can only use the conservative CPU governor. This means lower clocked speeds will be preferred as the CPU actively scales itself, and will take longer to ramp up to the higher speeds. But we're talking about maximizing battery life so that isn't necessarily a bad thing.
3. Try to keep screen brightness down, minimize usage of other radios (Bluetooth, GPS). Sounds like you already do this though. Rogue apps have also been discussed but if awake time != uptime then that's usually not the case.
As also prevoiously mentioned, it is possible you have a defective battery and should go about getting a new one from them though I'm not sure how that process goes... someone here is bound to know though.

I definitely stand behind adrynalyne's experimental undervolted. You can find a link in the kernel thread on the android development section of this board. He makes a sense and AOSP version. I've tried some of the newer ones like Chad's but I love the longevity and stability of adrynalyne's too much to live with the switch. As aforementioned, if you decide to use setcpu, make sure to only use the conservative governer. Ondemand will cause it to freeze! Otherwise it's rock solid.

Root/rom/battery question

Droid incredible. Rooted, virtually every rom through rom manager causes my phone to battery to drain very fast.
After a charge itll drop to 90% in about twenty minutes. Iv heard thats a droid thing.
From that point, it steadies but still is losing juice FAST. Phone has been awake for 8hrs today with light usage and is currently at 70%. Gps off, wifi off, etc. No vibrating feedback, auto brightness.....all settings geared for battery conservation.
Im using Incrom 1.6 with a stock kernal. Any ideas or thoughts are appreciated as i dont stop hearing that everyone in the world is rooted and enjoying their batterys new ability. Ohhh, btw extended battery, red htc one in case that matters.

Try flashing some new kernels..try a couple out. If that doesn't work did you over charge your phone? Or use a car charger?
sent from my Dinc

Its not the battery cause when i revert to stock the battery is normal for what im used to. The change is noticable wen i use any of the custom roms.
Right now wrkng on flash radio, hit a bump waiting for email back.
Ne other suggestions from u or nebody wud be apreciatd

Everybody's definition of "light usage" is different. Losing 20% in 8 hours doesn't seem that bad to me unless you litterally never turned your screen on. That said, here are some things you can try:
1. I've found that the auto brightness sucks and I'm better off just manually setting it to 25% or so. That's fine for indoor use and you can't see the screen in bright sunlight anyway regardless of the setting so why bother burning battery trying?
2. Try flashing a kernel that allows you to underclock and undervolt. Perhaps one of Ziggy's nonHAVs kernels (I have found that HAVS kernels to be unstable, but YMMV). Either use the smartass governor or setCPU to cap screen off at 384 MHz.
3. Carry a charger with you

I'd see what is using your battery in settings.
Also, you could try chad's sense (12/28 I think) incredikernel, which sets the max clock speed really low when the screen's off (defaults to smartass governer).
If you wanted to try CM7, gingerbread has a much better battery usage UI that'll give you a nice graph of battery usage vs. time for phone awake time, signal strength, wifi and some other stats.

[Q] My battery life is atrocious [CM 7.0.3]

Last straw was last night. Had 13% battery life left before softball last night and knowing I wouldn't use my phone during the games, but having been burned by my battery before, I shut my phone down before the games. Played softball for two hours then turned my phone on. Booted up long enough to see that I had 0% battery before it shut down again.
What am I doing that's causing this? I get maybe 10 hours out of a Seido 1750mAh battery. I have no apps that do background updates. I keep my display on "dim" most of the day. I go most days without even making or receiving a single phone call!
Ideas? Thanks for any help. This is really frustrating.
Cyanogen Mod 7.0.3
Kernel: 2.6.37.4-cyanogenmod+ [email protected] #27
Baseband: 2.05.00.06.11
Seido 1750 mAh battery

I'm not sure, but there have been claims that Seidio inflates their numbers and their 1750 mah battery isn't actually that much. Has this been something that has been happening gradually? Like your battery life is degrading over time and now it's at an unbearable point?

Try a different Kernel or Baseband. I'm using MIUI w/ incredikernel and get great battery life w/ stock battery. I'm also using 2.15.00.07.28 Baseband. I use SetCPU to set a screen off profile of 245min 245max, havn't noticed any lag while having that set. If you wish to update your radio easily you could download "Inc Bits" from the market. Great app has all of our phone radios, all you need to do is rename it and move to SDcard.

Agree with tcberg2010 here. Try incredikernal with Smartass governor. Check out vipermod. I was having intense battery issues which i posted about a week back. My suggestion would be to get spare parts app and check partial wakelock to see if anything is keeping your phone up. I use maps occasionally and it turns out that it was causing partial wakelock constantly. After disabling a locations and gps i am back to standard battery life. Looking forward to next cyanogenmod update, hope there is a fix...

If your phone died while it was turned off, then I would either have battery tested or get another one it could have an internal problem.

Yeah unless the phone some how got turned on in your pocket (I'm not sure how, but it has happened to me), There should be minute if not no drain on the bat at all. I'm not sure where you can get it tested, but I would certainly be wary about that bat. Do you still have the stock 1300? I'd check to see if it looses charge while the phone is off. Maybe there's a short in the phone.

Thanks for all the suggestions. I'm at about 10.5 hours right now and 7% left with the only thing I've changed being the battery. I went back to my stock battery. Going to try a new radio first, then vipermod.

try the "battery moniter widget" from the market. it keeps perfect tabs on your battery, can tell you the REAL mA of your battery, temp, usage stats, all kinds of stuff. it's really a good app to use to watch your battery...you could also use MIUI, and watch your battery life almost double. it's superior to CM7 in so many ways. and the people that have used both, i think pretty much agree...

[Q] Horrible EVO 4G Battery Life no matter WHAT I do!

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.

Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom

Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/

You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.

Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/

Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

I had an Evo, loved it,but the battery was trash,even when I bought my 3500 mah battery, the juice in it wouldn't last a whole day,sorry man,there's just no hope for that phone,without undervolting properly

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.
