Battery life is garbage.

I need help my battery life is terrible and I don't know how to fix. I have a battery information app and the battery chart drops.

We're going to need more information than that to help you out.
ROM?
Kernel?
Name of "Battery Monitoring" App?
Current Data use?
Signal strength in your area?
All of these will be very helpful in figuring out what your issue is.

Try to be patient, I'm a little new. But here's what I know.
Froyo 2.2
Kernel 2.6.32.9
Battery Monitor Widget App
Data usage isn't high.
I don't know how to find ROM
My display takes 93% but my brightness is all the way down and my signal is always pretty strong.

Im guessing your one the stock at&t froyo. Think about going into the captivate android development section and flash a custom rom. They seem to provide better battery life and are much better than what came with this phone.

You can also disable wifi, bluetooth, and GPS when not in use - that should help.

In my experience the fastest way to better battery life is flash a new kernel. speedmod-kernel-i897-k13e is very stable. Also turn off auto-rotate and auto brightness.

A big battery killer for me is background data and auto sync, I leave it all off, along with the stuff every one else said.

Also, try calibrating your battery.

The only thing I've done to my phone is root. And I've turned off all the auto stuff, I have no idea how to "flash the rom" or anything else.

If your display takes up 93% of battery that's usually a good sign, it means that there's probably nothing in the background sucking up all the juice. Have you tried "bump charging" or replacing the battery? They do tend to go bad or lose calibration if you've overheated them one too many times.

Whenever I charge my phone it seems to get extremely hot. The battery app said like 115° to 120°

In my experience, the jk4 modem has the best battery life.

Try Juice Defender in the Android Market, made a big different for me.

In my experience Froyo roms have all been garbage battery life *first leak, stock, Perception, Cognition, SuperNova, Phoenix Unleashed* I could never get more then 10 hours on the battery and less with wifi on. Now with GB *perception 2 beta 3*, I get 18 hours with Bluetooth on, Background Sync On, under H *3G*, and the original battery that came with the phone. I am putting up with some of the issues that 2.3.3 has but to me I cannot go back to froyo as my battery life has never been this good Including with jf6 2.1 that originally shipped with my phone.
HTH,
Charlie

I put it on the charger. Only went up to 35c (95f)

While that may be the case, it doesn't always provide for the best signal. You have to test each one and see what works best for your area/situation.

Your battery temp seems very high. You may want to swap the battery before trying other things. Is the phone new? If so, At&t store should agree to swap it out for you.

What's the best method to save some battery on this battery draining phone?

If you use the device a lot, and enjoy using it a lot, don't sweat it. The prior post has some good suggestions and I recommend reading through the battery life thread in the general section, good info there too.
one can find themselves obsessive with battery life performance to the point of not using the full potential of their device to their enjoyment - like me.
I'm waning myself off of caring too much, making progress...

+1 to this.
I am using Seanz sky icecream sandwich rom, I also run Juicedefender on aggressive I get a full day and halfs worth of battery with moderate to heavy usage.

Battery life

This is probably one of the worst phones on battery life that I have ever had... No matter what I do, what tweaks I use of what rom I'm on... I always only get 7 to 8 hours of battery with 1 hr screen on time.
I honestly have no idea what to do... I'm so sick of it. Anybody have any suggestions?

Seriously?
I have been on my phone all day with a full charge and I still have about half the juice. I am on stock 4.0.4 ICS. The one that droidstyles has in his guide. The Rom that came with my phone sucked on battery. This Rom works great for some reason.

What are your settings on? Post your settings (like screen, whether GPS is on, ect), a lot of times it has to do with your settings. I used to have so-so battery life but I tweaked some stuff in my settings and am very pleased with the phone.
Believe me, if you want bad, try the Droid Charge. Worst 4g phone I have ever had in terms of battery life.

This is on clean rom. Ignore the screen percentage, going down since this was a recently flashed rom.

I have nothing running... Only thing that I actually did was run v6 and I am running kt kernel
I'm on pure motives rls7
I'll add a screen shot of my battery status tomorrow cause I just plugged in

I get 30 hours with 5 and a half hours screen time.
Idk why your battery life is so bad.
I have power save on, no vibration, and sync set to manual. That's about it. Battery life for me is amazing.

Possible Idea
Don't know if this problem could occur with different ROM's, but I had issues with a runaway process that kept showing up. Maybe try Developer Options -> Show CPU Usage. I noticed that one called gsiff_daemon kept showing up at the top and was making my battery drain extremely fast. Everyone on this forum said it was a common issue and that it wasn't a crucial file, therefore I should just change the name so it wouldn't get accessed.

On RLS7 and kt kernel? This kernel has capabilities for overclocking/underclocking & overvolting/undervolting. By default your min Mhz is set to 384. Go into ktweaker and lower it to 96, test your phone out with a scaled stress test (play store app for stress testing). Then you can also go into the extra settings of ktweaker and set the Mhz for when your screen is off in addition to the governor (many options of which some are powersaving labelled).
If you want to save more battery read the kernel's thread to see starting undervolting values and lower from there while testing your phones limits. More undervolted you are, the less battery your phone uses for that particular frequency.

You obviously never had the thunderbolt, now that battery sucked. You have to let the rom settle in and your battery will improve. Usually for me the first day not so good after that everything is fine.

I had a Thunderbolt. Yep, now that was poor battery life.
My S3 gives me 12 hours if I use it heavily. Typically, at 16 hours, I still have 40% remaining. I leave WiFi, bluetooth, and GPS on 100% of the time.
As bad as your battery is, I would suspect that you have a poor radio signal.and the radios are cranking up the power to work. Try using WiFi or turning off mobile data for a while to get the LTE radio turned off.

man, i barely get 8 hours at times

This. For example, I have a 4g tower nearby at work, normally (4-5 bars). But sometimes it disappears, and I end up on a 1-2 bar 3g tower for the day. On those days, my battery life is around 8hrs max, barely using it. On good signal, even with crazy heavy usage (4hrs screen on and lots of 4g web browsing) I can get over 8 hours.
Signal strength has a LOT to do with battery life.

Check your Google account sync - could be something in there is not syncing correctly. Settings / Accounts / Google.
I had this - Internet Sync was not working but kept trying burning CPU, network, and battery. Disabled the failing sync and all was better.

Is it switching between 3 and 4g a lot? Constantly searching is rough on a battery.

I seriously doubt you guys are getting 7 plus hours of screen on time with the stock battery. If you are then you are charging it at some point.

I am using stock battery on stock jellybean leak and get 30+ hours with 5.5 to 7 hours screen on time you can see from the pics above that we are not charging. The bar would go UP at some point if we were.
I just have my phone set up the perfect way to get maximum battery life.
It's simple. I personally have nothing to gain from lying about something so silly as battery life.

[Q] My battery life sucks! How is yours?

I'm running HyperDrive RLS 5 with the stock kernel and like the features but I am on my phone a lot and my battery is suffering. I've seen people getting 20+hours of battery life on their S3 with 3 to 4 hours of screen time. Right now I'm at 7 and half hours with 2 and a half hours of screen time. Twitter, Facebook, Instagram, text, and phone calls. I'd like to keep with the phone but I have an upgrade and may jump ship. What Roms and kernel combos are you running that are yielding this stellar battery life I hear of? Please help before I do something brash and get a Motorola or even worse an iPhone, ugh!. Thanks guys!

I run Carbon ROM +Ktoonz. I regularly get 4 hours of screen time.
My best battery life was from Synergy +Ziggy or Lean or Ktoonz. I got 5 hours of screen time.
iPhones have crap battery life, with no option to expand battery, undervolt, or underclock. How would that help you? You also can't freeze apps, make screen off profiles, etc. That's like getting a Dodge because your Honda wasn't reliable enough for you.

Clean ROM and lean kernel does wonders for me
Device idle puts my at about 80% with very little use.
Battery will last all day with very very heavy use.

Thanks for the input, gonna give the ktoonsez kernel a spin. Hopefully this helps. PS I'd never go to an iPhone. I like technology not toys. #teamdroid

I have this set up but I feel as though I'm getting iffy battery life. I keep my screen pretty dim and am on consistent wifi 100% of the day with mobile data off, no games or any CPU intensive tasks, and I get maybe 15 or 16 hours of battery life with 2-3 hours of screen time. Perhaps that is good though? I keep seeing people write about 24 hour battery life and I just don't see how.

That's pretty good. Screen on is the most important stat. You could not touch it, put it in airplane mode and boast about how many hours. I would assume some of those people are forgetting to mention they have extended batteries or are charging at some point.

Battery is bad in s3

Please someone tell me how to increase battery life on samsung galaxy s3 GT-I9300 ????
I am running on android revolution hd 17.0 ( custom rom ) on my s3 . AND battery life is too bad just 5-6 hours is the timing of my battery !!
So anyone can resolve my issue ?? Plz help me
Sent from my GT-I9300 using xda app-developers app

Something wrong. S3 should easily last a day. Most likely your phone can't get to deep sleep, because of some app. You can try to find which app went bezerk with BetterBatteryStats app

Only idea i have is brightness and if some application is draining your battery
Sent from my GT-I9100G using xda app-developers app

Brightness and the autosyncing that's going on in the background.

Also download amd try fastdormancy from store
Sent from my GT-I9100G using xda app-developers app

It really depends on what you're actually doing with the phone in those 5-6 hours. It's reasonable to even hit 0% depending on what you're doing.
Look at your battery stats in the Settings Menu and get something like BetterBatteryStats. Find out why your battery is draining. If it's something you don't want - fix it.
