Any tips on how to improve battery performance in the evo?

Dark wallpaper, root, custom rom, set cpu, push notifications instead of update intervals.

Screebl
I've just started using a market app called screebl and so far I like it. It works by having you set the minimum screen time and screebl determines the angle of your device and keeps your screen alive accordingly. For instance, laying flat for a period of time will turn off your screen. It's free and customizable, worth checking. There might be a "super" power app released soon.
Good luck, there are some apps that help with screen and wifi usage to increase the time between charges.

I'm a truck driver and I'm a heavy user.
I did too before I made the changes below. These all work with the Stock Rom.
1. Installed No Lock (so that I don't have to swipe the screen to unlock, just push the power button)
2. Set screen to turn off in 30 seconds.
3. Installed Brightness Widget (allows changing the brightness from the home screen
4. Installed Screen Filter (lets me really darken my screen at night.
Try those and see how you do.
5. I then flashed the Infused Rom (I now get up to 10-14 hours)

Also, Turn off GPS and Wifi when you're not using them.
Battery
After much experimenting and monitoring of battery use I find that the biggest drain is the screen display, so go to settings-->display-->brightness and lower the screen brightness as low as you comfortably can. Also when you you are not using the phone make sure the screen is off, I have trained myself to automatically hit the power button every time I put down the phone. If you listen to music through your phone make sure the settings on your music players allow the phone to play when the screen is off and turn the screen off while it plays.
GPS also drains the battery, so I keep it turned off when I don't use the Nav. When I use the Nav I know the battery will drain at a rapid pace, nothing you can do there, even if I have the phone plugged in to car power while using Nav it still drains the battery! Drains slower than unplugged navigating but still drains.
If your watching videos then your S.O.L. there's really nothing you can do that will increase battery life enough to make a difference during video playback.
I get 10-12 hours with regular use and stock rom. Worst was 8 hours best was 24.
Thanks for all the advice this has really helped my battery

3. Installed Brightness Widget (allows changing the brightness from the home screen
There was a recent post that showed a shortcut for changing the screen brightness from the homescreen without any additional software. First, turn off auto brightness. Second, tap and hold the menu bar at the top. Third, slide left to reduce the screen brightness and right to increase screen brightness.

It seems that Samsung ****ed up and included phone CPU/screen/etc usage when measuring battery charge current.
This means that the 600 mA stock battery charge current limit isn't just going to the battery, it's split between battery/screen/CPU. If screen/CPU/etc go above 600 mA (Navigation at full brightness seems to be the most common way), battery starts draining.
It also means that unless there's something I'm missing (which I could be since the MAX8998 datasheet is super-ultra-secret), our phone isn't going to be able to do proper charge termination - if the screen is on/CPU is running, it will cause a falsely high battery charge current reading, which will cause charging to fail to terminate.
Juice defender
I found that juice defender helped my battery and i just use the free version it's a great app

look in about phone battery use to identify the biggest battery user, it should be the screen. anything else and there is a problem.
the cell standby may go high on froyo rom, turning on flight mode and turning it off will correct that, it's an android bug.
on gingerbread the android os or android system may hog battery occasionally. some think it is the wifi sleep policy but it pops up on me without setting the sleep policy. the fix for that is to pull the battery for a couple minutes and put it back in and restart the phone.
next manage the screen brightness
install a custom rom, there are issues with certain firmware keeping sensors active wen they shouldn't be.
turn off unneeded sync options (i find that auto fetching my email uses a lot especially with my gmail already set to sync),
use wifi when you use the internet if possible, turn it off when out and about.
monitor cpu useage of apps that are cached in the task manager
kill apps that use cpu
if needed turn the max cpu clock down to 800mhz
set "use wireless networks" for location when possible for general location (limited to city level at times)

Actually, high cell standby is OK if the phone is screen-off often.
Cell standby is always my top user - but my phone is sitting on my desk with the screen off frequently, in a location with weak signal. Weak signal makes cell standby usage go WAY up.
Syncwifi application is awesome for extending sync settings to gain more battery

I agree JuiceDefender works!! I had to charge in the middle of the day. Now with moderate use it will last all day Im on stock Rom.
I easily get 2 days out of my Infuse, no idea how some of you are managing to only get 8 hours. After rooting my phone and freezing the bloat i easily get twice the battery life of my prior iPhone 3GS.

Green Power vs JuiceDefender

Hello everyone!
I was just wondering between these two apps...
Which one works better for you and if will be great if you can share your configuration!!
Also, does anyone knows is any of these two disable whatsapp and gmail notifications?
Many thanks for sharing!
Cheers!
IMHO
I can answer about Green Power Premium:
It doesn't have such option like disable notifications. He does such thing like disables data connection for amount of time you chose (for me it is 15min) and then enables data connection for amount of time you choose (for me it is 2min)
Now my Galaxy Note works 2 times longer (from 10h to 20h)

WOW! double time!!
thanks for sharing!
I have been trying both, and while both of them seem to deliver a noticeable reduction in power draw (actually in my case a dramatic reduction), of the two I'd have to give my vote to GreenPower (I'm using the full version). The power reduction is at least as good as Juice Defender Ultimate, and the premium version is significantly cheaper.
Both work by turning various features (mainly Wi-fi/3g/BlueTooth) on and off automatically, but as result can cause delays in things like receiving push-mail and that kind of thing. With Juice-Defender I found this to be quite noticeable, but I'd have to say that with Green-Power I haven't really noticed it slowing down messaging or anything else.......
I've used them both - and deleted them both. I'd rather manage power myself.
i am using 2x Battery for me this is the best. simple and clean.
I usually use JuiceDefender but decided to try out Green Power. I really like it but I have a hard time getting my phone to sleep properly on GP.
i use widgetsoid and just enable my connection when i want it (wifi/3g)
i could never find the proper app that did exactly what i wanted- rather just have control.
going that was and using the phone an average amount my battery goes from 100 -> 75 from the time i wake up (7am) to the time i got to bed (12-1 am)
the 2500mah battery is pretty good!
With JuiceDefender I can get my phone to sleep 95%+ of the time but with GreenPower, my cpu is only sleep 40%+. Can anyone give me tips to get my cpu to sleep more to preserve battery?

Just out of interest, what happens when you browse the web and GreenPower has turned off the Data Connection?
Or you're watching a youtube video and it decides its time to turn off data?
Tried both versions and found green power premium to work better for me. (Price was a good point too.)
However the next day I found that if I left my phone for a while (Around 1 1/2 to 2 hours), the display would not turn on and If I called the phone it would not ring. Only way to fix this was to press the power button for 10 seconds to reset the phone.
Uninstalled green power to see if this was the cause and hasn't happened since.
Was wondering if something similar has happened to other people?
I had to go back to JuiceDefender since I couldn't get my phone to go into deep sleep with GreenPower.
Hi, i went for Green Power. I found it simpler to configure, more focused on the job. Juice Defender has to much possible settings and complexity, this makes it a great tool but might also lead to poor efficiency.
I have never used green power before but im on juice defender. I have experienced auto turn off by the note due to a set cpu settings that govern lower clock to cpu at a certain condition. Due to the big display on note i think lower cpu clock wont do it. Because of that the device turned off itself. Upon failure to operate. Hope this solves your problem
I have tried JuiceDefender but ultimately prefer to do everything manually. Some how I always feel the auto manage apps will have everything off precisely when you need it. I use the SwitchPro widget to quickly enable/disable the various radios from my home screen and it works great.
@ Aldragor
I have/had the same problem. In the beginning I thought that my launcher would be the cause for this problem, but after I disabled my Green Power Premium it hasn't happend since now.
Juice defender ultimate, the feature of switching 2g 3g on stock ROM alone was worth the price!
After figuring out how to config GreenPower properly, I went back to it.
I used JuiceDefender and thought it was great.... when it worked. However, I used it mostly as a scheduler with about 15% battery saving which I took as the icing on the cake.
I want all connections on during the day (peak) so I can take skype calls, etc.. When I'm home, I just want to periodically check for mails, etc (so have connection enable every 15min) and when I go to bed I don't want to be disturbed by emails, messages, etc but still want phone/sms on in case there is an emergency. And most of all, I didn't want to have to manually do that every day.
Problem was that it never really stuck to the schedules. This was the ultimate version but it was a crack as they never offered the ultimate on a trial. I wanted to evaluate the ultimate and buy if it did the job. So, it might have been a bad crack which caused the problem, but I guess I'll never know as I don't want to risk wasting the money if the schedule problem persists.
I am a lover of juice, it keeps he juice in and right

Well it looks like you were on the screen for a while...plus had some media playing in the background...music or videos?
I'd like to see the more detailed one...like how many hours screen was on, or clicking the battery graph at the top and seeing what it displays there for awake and screen time length on that...
Cause if the screen was on for most of that time...then what do you expect? If the screen wasn't on that much...then something sounds a little strange...

Set any sync you have to off or the maximum interval.
Adjust the automatic screen brightness levels, I posted a thread, "custom backlight settings". Turning down the brightness levels will help tremendously.
For the best battery benefit, turn automatic brightness off and set the brightness level as low as you can tolerate.
Set screen timeout to 15seconds.
Turn off any vibrate notifications or keyboard vibrations. You'd be surprised how much battery vibrate uses.
Download Justin inverted gapps. They are mostly a dark black theme.
Also set your wallpaper to a black or dark background. Anything but white! Making the screen mostly show darker colors reduces battery consumption.
Turn off auto update in play store.
Turn off WiFi, GPS, and Bluetooth whenever possible.
Advanced users only... you can under clock to 800mhz. This may produce some lag, but will help save battery.
You can also under volt, there are plenty of threads on here describing a safe way to go about doing this.
Hope this helps. And good luck

After seeing that Mediaserver usage I already turned off all the syncs. I can see some improvement and right now I'm reducing screen dim level.
The only thing that is bothering me now is sometimes my processor usage is 100% for a good 10 minute or so (no foreground process running) which makes my phone really hot. This is only thing now I need help from you guys, thank u all for relying. mg2195 i'm attaching screen shots.

1. Turn off Battery Saver under Settings/Battery. This is false hope and more of a placebo. It usually kicks on when you are already really low on battery and it usually just down clocks your CPU and can make your phone sluggish.
2. Turn off Automatic Brightness under Settings/Display/Brightness. When the sensor on your phone reads the light around you, it likes to shift the brightness on your phone from really high to really low. This effects your battery. Turn that option off and leave your phone on half to 1/4 max brightness. 1/2 is usually just fine. You will get used to this brightness.
3. Turn off Location Access. This is probably one the biggest battery wasters out there and you don't need it running all the time. It is located under Settings/Location Access. Turn off or uncheck everything here. If a program needs or wants it on, it will request it when you are using that app. Most of the time it is usually for Google Maps. As you can tell, this also turns off GPS.
4. Let your phone sleep, but not too soon/long! Under Settings/Display click on sleep and change it to 1 or 2 minutes(preferred). Nothing shorter, nothing longer. Nothing longer because if you forget to turn off your screen, you don't want it sitting there for 5
minutes wasting away. Nothing shorter because turning it back on after 15 seconds because you were thinking will only cause the screen to demand more power to get it restarted, thus draining battery.
5. Facebook = Battery Killer. I get it, you love Facebook. That is ok, but your battery doesn't. There is hope though! Open the Facebook app and slide your finger from the left side of the screen to the right side of the screen. Now go all the way down to "App
Settings" and make these changes. #1 Refresh Interval = Never: This will prevent it from waking up your phone/battery and refreshing automatically when the phone is off. When you launch the app, it does this for you, so why have it do it when you are
working/sleeping? Plus you can always manually do this by pulling down on your News Feed. #2 Turn off Messenger location services. You don't really need this on. it likes to activate your GPS(battery hog) and let people know which city you sent that post/message from. Unless you care that people know you are in Butt****, Ohio, you should have this off.
6. Streaming Music kills battery. Do you have 80gb of songs at home on your computer? Then why do you stream Pandora all day? You having unlimited data is not a good excuse. If you can, put all those songs on your SD card/phone and listen to them using Google Play Music app. Buy a bigger SD card if you have to, they are not that expensive. Or just ask Santa.
7. Turn off vibrate on touch/haptic feedback. Usually located under Settings/Sound. That little motor that tickles your finger tips when you touch the screen actually uses a good amount of power. If you are really looking to get the most out of your battery, turn this off. I leave it on because I could always go for a finger tip tickle.
You don't have to use all of those, you can pick and choose if you like. I do. I hope it helps you out. Let me know.
Fun Fact: The takes more power to show the color blue on your screen than any other color.

Yeah, well, you need location services for Google Maps. It's nothing something discrete for just one application. (Meaning, if you turn off location services globally, it turns it off for everything. If you turn it on, you can go into individual apps and see if you can turn off location.) However, you can go into Google Now, menu on the bottom right, settings, Privacy & accounts, Google location settings, and turn off location reporting and location history - unless you really want that in Google Now.
6. Streaming Music kills battery. Do you have 80gb of songs at home on your computer? Then why do you stream Pandora all day? You having unlimited data is not a good excuse.

1 - Agreed.
2 - This is mostly preference and will not that huge of effect on your battery. Having the display on the brightest setting will always drain more than the lowest setting, but the auto-brightness changing does not hurt the battery, it's when it sets the brightness high that it does. I have auto-brightness set and I'm doing pretty good.
3 - Location services are only accessed and turned on when requested. For example, when you open maps, or have geotagging enabled on the camera. Just leaving it enabled in general will not be that big a deal.
4 - Mostly preference, but setting it too long can have more detrimental effects than just battery usage. For example: forgetting to lock the phone and shoving it in your pocket while the display is still on can result in apps opening or calls being made.
5 - While you're at it, just quit facebook altogether But seriously, the more "social" apps you have running, the more you have apps waking up the phone and hitting data in the background. Instant messaging can cause battery drain as well. As for me and facebook, I do not have an account at all, so I don't use it, and can't really say if it really is a drain on its own.
6 - Agreed. Either put music on your phone or use the caching available in various services like Spotify. I'm a Spotify premium subscriber and it's totally worth it.
7 - This will have a negligible impact on your battery.
I'll add this: If you're into figuring out what's causing battery drain, install an app that monitors wakelocks. I use Wakelock Detector. Wakelocks are going to be your idle time battery killers and apps that abuse them will cause excessive drain. I'm sitting at 8% awake right now and my battery easily lasts the entire day with around half battery remaining on my Mini. You can find apps to blame for battery drain with an app like this easier than an app that just monitors battery usage.

6. Streaming Music kills battery. Do you have 80gb of songs at home on your computer? Then why do you stream Pandora all day? You having unlimited data is not a good excuse. If you can, put all those songs on your SD card/phone and listen to them using Google Play Music app. Buy a bigger SD card if you have to, they are not that expensive. Or just ask Santa.
7. Turn off vibrate on touch/haptic feedback. Usually located under Settings/Sound. That little motor that tickles your finger tips when you touch the screen actually uses a good amount of power. If you are really looking to get the most out of your battery, turn this off. I leave it on because I could always go for a finger tip tickle.
You don't have to use all of those, you can pick and choose if you like. I do. I hope it helps you out. Let me know.
Fun Fact: The takes more power to show the color blue on your screen than any other color.

Getting reasonable battery life

Hey guys, just wanted to throw out what I have found re: reasonable battery life.
As most of you know, you can tell when the phone is not getting what I consider reasonable battery life.
Here are the things that I found worth doing:
1: Greenify apps if you can. Unfortunately, Facebook is one of the worst violators of battery and if you greenify it, you will go a long way towards having decent battery life. Of course, then you don't get your Facebook notifications, but for me, this is a plus.
2: Battery Doctor. You can set it to kill apps when the screen is off. There is a whitelist as well so you can keep certain apps running instead being killed.
3: Adjust the auto brightness curve. This seems to work well. Keep the screen reasonably bright but no more than necessary. I think this might work better than just a fixed brightness level because if the area gets really bright, at least the screen will react and become brighter so you can still see the screen. To me, the screen is a battery killer.
4: If you have a super AMOLED display supposedly you can black out the screen with a dark UI. Not sure how much this helps.
5: Custom Kernel. I have only tried IceCode and insanity. Both were giving reasonable battery life. I tried the lower voltage tables in IceCode but didn't notice much difference.
For me, even though I tried several different ROMs, if I did the above, I got reasonable standby/sleep times. It was usually 1 to 1.5 percent per hour in sleep. When the screen was on, battery life was totally dependent on screen brightness. For me, reasonable is with decent use - check/reply to mail a few times an hour, browse web, text, talk abut an hour a day, etc... from 7a-3p and still have around 70% left. For me, the phone still needs charging every day though. Any other tips???
For Facebook, I use the Tinfoil For Facebook app, which is pretty much just a wrapper of the mobile browser version. Beside the battery drain the official app causes, the privacy concerns with the addition of them listening in on your mic makes this worth it.
Hi all. Can anyone please suggest which Rom & kernel combination gives best battery life for Ville c2 . Main use is web browsing on mobile data & some casual gaming.
I recently got this device and am new to this (c2) forum.

I use the "Snapdragon BatteryGuru" application.
A feature I love is that I can set what apps have to be updated ever, when I use them or basing on my use. For example I installed Facebook, Twitter, a mail client and Skype on my phone. I can choose that the mail client has to be updated ever, Facebook and Twitter basing on my use, and Skype when I use it.
BatteryGuru can enable some features like the Wi-Fi or the Mobile data basing on my use. For example, I surf the internet between 8:00 AM and 3:00 PM. The Snapdragon's application registers this activity and it will automatically enable internet connection between 8:00 AM and 3:00 PM.
Another feature I like is that I can enable a low power mode when the battery reaches a choosen level and disable, for example, the mobile data, Wi-Fi, Bluetooth, apps update, etc.
Awesome app!
I saw that app. Will need to check it out. Sounds like useful features.
Thanks! I'll try Greenify with Facebook.
I'm quite satisfied with the AOSPA 4+ ROM (stock kernel). I unplug the phone at 9am and around 10pm - 56% battery remaining (with Greenify + Auto brightness + Dark UI theme) with normal usage like browsing/checking emails/phone calls every now and then.
