Note to mods: I copy pasted this question from another forum to get different answers. I am the same person, please be lenient.
Hello, I would like to improve my Evo's battery, because a few texts, a minute in the browser, and just scrolling through my email brings me down to 60-ish percent battery.
I'm running the latest MIUI with Tiamat 4.0.1 or something like that. I am also running JuiceDefender Ultimate.
My screen brightness is also at a constant low, too. I should have done more research on this phone, as I'm stuck with it for another 1.5 years. It sucks. :/
My friend's iPhone lasts for so much longer, it doesn't have a larger screen, but still..
What can I do to improve my battery?

You can undervolt with vipermod

I've never used MIUI so I don't know what options you have for kernels, I imagine all AOSP Gingerbread kernels, but if I were you in would try out different kernels, even a different version of Tiamat could help. You can also try calibrating your battery.
If none of that helps, try switching roms.

Won't ViperMOD hurt my battery?
There's always the obvious. Turn off what you don't need - GPS, 3G, wifi, Bluetooth, etc. I assume that Juice Defender helps with that but I've never used it. If you can use wifi instead of 3g then you should, it saves a lot of battery. If you're in a low coverage area, that will kill your battery as well. Going through your installed apps and uninstalling the ones you don't use will help as well. Back them up with TB first if you want to save their data or easily reinstall them later. Check your sync settings, if you have social networking apps set to sync every few minutes then that's also going to chew through your battery. Using push notifications instead of regular syncing can help - try FriendCaster if you use Facebook.
I'm also running MIUI with Tiamat 4.1.0 SBC. If you're not using SBC then you may want to try it out, it can help with your battery life. I ultimately gave up on sacrificing functionality for battery life. Instead I bought 3 extra 1500 mah batteries which came with an external charger. All together it was $11 on Ebay with free shipping, took about two weeks to get here. If you decide to go that route, you can just run the battery down and put in a new one... your friend's iPhone can't do that
I still use an SBC kernel even though my battery isn't usually charged through my phone. If I forget to charge my batteries or something, I'll sometimes put the phone on the charger when it gets down to 80-90% and charge it back up. When I do that the battery lasts all day and I don't have to switch batteries.
You can also buy an extended battery, but I didn't want a fat phone. I get just as much juice - if not more - from my cheap 1500s.

I'd recommend looking up Car-O-Dope's tweaks, it's helped me be able to run the governor at 128mhz-652mhz and not sacrifice any performance. This has saved my battery life. This guide will have you download rom toolbox and system tuner, and in system tuner you can undervolt your battery as well without having to run the Vipermod scripts. In rom toolbox I changed the wifi scan interval to the max amount of time possible, and changed the wifi sleep policy to never. I leave wifi on at all times, keeping the 3g off. My battery has never been better.

I seem to be having battery issues as of late. Been running Cyanogenmod 7.1 for sometime now...maybe 6 months lol havne't been on here in a while. I leave the 3G radio off due to it sucking battery faster than anything else. Here is what my battery currently says..
11h 11m 24s on battery
Android System--32%
cell standby--32%
Phone idle--30%
Voice Calls--5%
Display--3%
Do these look right to anyone? I would think that if someone turned off all data like myself and only used the phone for texting shouldn't it last all day? I'm lucky to get 15 hours sometimes....I have turned off everything. Bluetooth, Wifi, 3G, all syncing is disabled. I do notice when I turn the 3G radio back on the battery will almost instantly drop 10-15 percent within a couple of minutes...

Please keep in mind the apps you downloaded and the widgets you have set-up on your screens. Some apps require to be run in the background eventhough they are NOT used by you at the time, such as Google Talk, Qik, Fring, pedometer, and anything that needs to be "ON"...thats one of the culprit on battery drain you might want to look into.
Having one widget per homescreen is ideal, in my opinion..and learned that by having multiple widgets in one screen, is another culprit in battery drain due to it requiring to work upfront, for example, Facebook widget needs to be on constantly and updated for as long as that widget is there, regardless if you touched/used it or not.
Now, for the MOST OBVIOUS part...turning off GPS, WiFi, 4G, and bs when you DON'T need them, by following hot sexy COMMON SENSE, you should get AT LEAST 3 hours more on your battery. Pure sexy common sense LOL ;-)

Greetings,
I couldn't agree more with all the things you noted in your reply.
I rooted mine, and deleted many apps I don't use, but insisted on starting up
even if I had already killed them in the manage applications section.
But I was amazed at how short the life was in spite of having done that. I quickly
discovered (as you noted) that keeping 4G on, drains the batt.
In fact, for me anyway, it really drains the batt!
Just thought I'd mention it, because it was really surprising to me just how bad
an affect on the battery 4G was - bummer.
--Chris
Mine usually gets between 36-55 hours on a charge (record is 58 so far) with about 3-5 hours of "use" on the stock battery. I don't use it to play games or watch movies, just phone, internet, email, etc - widgets all over the place. Gmail push is always on as well. In fact, I unplugged it last at 10:50pm on the 28th (34 hours ago) and I'm at 48% still.
The biggest thing I've found is download setCPU and adjust the CPU frequency to 245 MHz when the screen is off. That saves a lot. Other then that I keep it at 998 MHz (max speed) all other times. I am playing around with tasker and turning airplane mode on while I sleep, but that seems to have a minimal effect, saving around 2% over 8 hours. I use tasker to turn GPS off unless I'm using one of my GPS-enabled programs, although that doesn't seem to do much either.
I'm running just a basic sense rom with a stock kernel, nothing special. rooted with clockworkmod and that's all I've done rom/kernel-wise.
If you actually use your phone a lot I'm not sure there's much you can do besides get a bigger battery. If you just use it mostly as a phone and less as a PMP or gaming device you should be able to get some nice results.
EDIT: Oh yea, and don't use a task killer (I don't). From what I've read those can actually cause the phone to consume MORE power as services are being killed and opened constantly. Android is very good about leaving tasks open in the background without them consuming power. Opening and closing them constantly is another story.
I wish I could figure this out too. I've been switching between a ton of kernels and roms and can't seem to find anything with good battery life. My phones been unplugged for about 2 1/2 hours and I'm at 53% battery life. No widgets running and just average usage.
Running virusrom and kings #9 and a lot of other roms and battery life is a joke.

What I have found to help most of all is to NOT use the Mail app - it drains the battery like crazy, especially if you are popping several accounts. Instead, use the gmail client and set it up to pop your other accounts, and push them to you. This literally trippled my battery life. And it is way faster than the 15 minute intervals that the mail app gives you. Give it a shot, you will be pleasantly surprised.
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.

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.

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:

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.
Hello everyone, I lately have been getting horrible battery life!! I keep brightness on lowest setting, use wifi when possible, turn down haptic feedback all the way etc. do my best to save battery!
So my epic is Rooted with CWM3, and the latest frozen syndicate rom installed. Is it because my phone is rooted and the syndicate rom drains it more? is that why i have bad battery life? Does having your phone rooted drain battery life?
I ordered a Seidio 3300mah battery and got it yesterday in mail. Put in phone, then charged rest of night about it. Im using it today and am still receiving poor battery life, my friend who has epic ordered a cheap hong kong battery and is getting better battery life? I read something about conditioning your battery and draining it to 0% then charge fully to 100%? How does this work please explain?
Can someone just please help me use my new battery to its potential and help me out here?

I have noticed no difference in DK28, EB13 or EC05 in my battery life. Do the calibration suggested in the post above. As for ROMs it is about personal choice. I have been with Bonsai for awhile now. I hear the ACS ROMs are very stable. Syndicate Frozen is good, Midnight is good. Read the OPs, learn what they remove and improve and see if that is what you are looking for.
Running SRF 1.1, with a custom theme, brightness at lowest setting, haptic feedback all the way up, because I need to know if someone is calling, I regularly get 30+ hours per charge. The two Chinese knockoffs I have get about 26 or so hours per charge.
I have recently seen a drop in my battery, spare parts on a couple of occasions should my phone would not sleep. Sometimes a reboot would fix this, but reflashed just to be safe.
After the reflash I was still getting bad battery life but spare parts showed no issues, so I started doing the airplane toggle again and that seems to of fixed it.

whats spare parts?
Spare parts is a free program available in the market place. It shows you more detailed statistics on what is using your battery juice.
Undervolting maybe. But I got stablilty issues. ymmv anyway.
My advice is
1. Set max clock to 800mhz and min to 200mhz. The CPU is volted -75 over 1ghz and 200 is volted the same as 100mhz. I use the Conservative governer but Ondemand works well too.
2. Get a good custom rom/kernel. CM7 and Frankenstein got the best through all my testing.
3. Brightness at lowest, turn off "Notify me when Wifi networks are available", Turn off syncing for contacts, the two GPS options, etc.
4. Take out as many applications as possible(Personal preference. I think it makes a difference) But I mean stuff you don't use. I take out Bluetooth, GPS, DRM, SNS, and most stock applications. If you're using Handcent you don't need stock SMS and vice versa.
5. If you're on 2.2 and lower I recommend a program like JuiceDefender to turn off 3G when your screen is off. The latest update on the free version removed the option to filter applications using data while the screen is off.
6.Enable Airplane mode on boot up. Then turn it off and use normally. TWS
7. Definitly calibrate your battery.
8. *Insert unreasonable battery tip here*
Oh and spare parts can be installed directly from the market. It's a program that allows monitering and for changing animation speeds and such. I don't use it for anything. You should also be able to go into settings -> about phone -> battery usage and see most of what spare parts would.

Especially with a new 3300mAh battery! I recommend the top two as the third didn't work for me.
Juice defender on aggressive mode and setcpu on conservative mode increases my battery life when on standby quite a bit.
Don't drain your battery to zero it destroys our batteries. Don't use juice defender. If there is no reason that you need background data on like when you are sleeping turn it off but some say that's cheating but their idiots. That will dramatically improve your battery alone. Do the airplane shutdown every once in awhile some that's cosmetic but don't believe everything that is told to you. Only keep apps installed that you regularly use. Use spare parts to see if any app is causing significant drain. I'm a battery life guru.... ;-)

Running Evo Deck 1.2.1, display at 12%, couple widgets, data off (using wifi at home) , sync off, and all of that. Underclocked, undervolted too.
Browsing, xda app, etc results in 20% battery usage per hour. Battery consumption is zero at idle, but drops like a rock if i use the phone at all.

I'm using Seidio 3500mah and enjoying the 5 days no charging. I use my phone mainly for texting/facebooking.

I'm evo deck 1.2.1 with sz 2.2.1
Setcpu at 245/1152 sz governor
Chainfire 3d
Battery calibrated
VM heap at 48
SD card cache set to 8192 on my class six
Brightness on auto
I get 20+ hours of heavy use, xda, music, browsing I'm sixteen so my girlfriend is ALWAYS texting me some pandora, youtube tossed in there
Oh and I'm using a live wallpaper (pixel rain) I keep sync on, gmail hourly everything else daily, weather on the half hour, right now my phone is at 17 hours with 38 percent left.
Under lighter usage ( more pocket time, less texting, less sitting around bored on xda and Facebook )
30 hours is pretty common

Zac95....I hate you lol.
Maybe my batteries are shot - their health shows "good " though. I have two OEM 1500 batteries that I swap, but I did buy an HTC 2150mAh, just waiting on my battery cover to arrive before I use it.

Battery calibration is very important, don't know how I lived without it
Setting the VM heap to 48 allows the dalvik garbage collector to run less, improving battery
Chainfire 3d helps with anything graphical, makes home using lwps smoother, games run better etc, also saves battery by making all animations, graphics processing more efficient
If you use apps2sd bumping the cache makes it faster, and more efficient saving battery
Also updating to the latest radios etc, and making sure your prls and profile is up to date is essential, many aosp users, formerly including my self forget about that stuff
I've spent a huge amount of time expirementing with different setups, I think I've found my phones sweet spot
I have loads of friends with rooted evos, mine has the best battery and is typically fastest (chainfire 3d) makes everything snappier
Maybe with all of this info you can test these apps / settings and find your phones sweet spot. Good luck man

Since I'm stock for now, my battery sucks.
thinking of buying this since its apparently the same size as the original.

what do you guys think? Can't get a 3500 due to my otterbox case

I wonder how the mfg pulled that off? My HTC 2150mAh battery is twice as thick as the 1500. I'd bet that that eBay battery will not yield the stated 2100mAh.

I just bought 2 batteries and a wall charger from amazon, and I just switch out batteries, no more charging or being tied down to a seat

I'll agree with Zac here,
evo 3d with CM7 nightly, SavagedZen 2.2.1 CFS. removed all the crap i dont use or think they suck the battery down. live wallpaper etc.
InteractiveX governor, 245-1113mhz
No setCPU.
no juice defender
no taskkiller.
no 4g - no gps - no wifi
blutooth ON
3g always ON.
battery calibrated is a must
display set to manual around 33% brightness. but i change it on the fly (swipe the notif bar).
Now the results are pretty interesting here:
With the stock battery and all the above; if the reception is good, i can go for 2 days with moderate usage. yes i know i night i sleep, so it idles nicely.
If the signal is not so good, it will destroy the battery, and can't really get anything more than 13hours.
My typical use:
unplug at 10am.
use the phone normally.
plug it back in at midnight that night, and i would have between 35% or up to 67% battery left in the phone, depending on the factors mentioned.
Which to me, going all day is all i wanted before i started tweaking. Mission accomplished.
The quality of the reception is a killer, i'll tell you.
I bought a 3500mah battery from the same company, and it is trash.
are there any extended batteries that fit in an otterbox commuter case?
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.
