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°

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.

Use BetterBatteryStats to look for any unusually high wakelock times.

Do you know what your time since charged was? (I wish it would display total time since charged there...) The "since charged" definition seems weird and hasn't reset on my phone in ages... I've tended to use "since last unplugged".
Pandora appears to be your #1 wakelocker. eBay mobile seems to be pretty bad too.
NetworkLocation wakelocking can be eliminated by unchecking all of the location features in Settings except for when you want network location/GPS.

I assume you were listening to Pandora during that time, in which case, that wakelock is normal. Playing music from your device will also hold a wakelock when the screen is off. If you weren't listening to Pandora at all, then something is wrong.
Whoa. Why the heck is eBay holding that wakelock . Check your notification settings and if it's still holding it, clear its data and try again. Otherwise, I'd uninstall it. I always use the browser to access eBay anyway.

No. In the device settings, turn GPS off until you need it and leave network location checked/enabled. Go into Fancy Widget under weather settings and UNcheck/disable GPS location (GPS is unnecessary for weather updates), verify that network location is checked. Then, I would recommend changing your refresh settings (to update less frequently). I'd bet you have it set to update more frequently than an hour. I also use Fancy Widget and mine is set to 3 hours. This should take care of your network location wakelock (unless another app is also updating with network location).

BTW if Wifi is on but not connected, in Froyo it seems to scan way too often regardless of build.prop setting. Netloc should wakelock less if wifi is off.

Hey ent i noticed after trial and error that phone stays on 100mhz while charging ?but when disconnected it hits deep sleep and there has been no bad wakelocks.wonder if thats y we get slow charge

I installed BetterBatteryStats because I was curious as to why my phone always seemed to drain so quickly. I am rooted and running infused 1.5.3. I have very few widgets, one that actually accesses anything, and don't do much but surf the net or the forums in the morning. I would unplug it at 6:30 and go to work. By about 8 or so I would already be at 90% or less. That was me hardly using it. Well I hope I got my answer. Apparently Beautiful Widgets was KILLING me on the wakelocks! I wish I took a picture of it before I uninstalled it but jesus it was bad! Thanks for the good info I'm gonna keep an eye on it and see how it does.
Oh funny thing is, I was not even running Beautiful Widgets! I use Fancy Widget instead lol.

No, slow charge is a few other things. ALL android phones wakelock when charging.
The phone shouldn't count CPU/screen/etc usage against charge current at all but it does. It seems to do it less so on GB. Still does it, but the spikes seem lower even if I crank stability test. Gonna be a while before I can test a navigation run.
Seems like on GB, difference between screen off and running stability test with screen on is about 200 mA. Haven't tested in that much detail on froyo. Another way of putting that - putting the screen on and cranking CPU will reduce charge rate by at least 1/3 of the 600 mA charge limit.

Juice defender?

I use the widget to turn data off while not using phone to save battery but it never disables data when it says mobile data off. Anyone know how to because I want my battery life to last longer.

Quite possibly a bad battery. Your battery shouldn't drain when the phone is off.

Does it drain when the battery is removed from the phone?
Sent from my LG-P999 using XDA App

you should download a cm7 nightly my battery lasted from 10pm - 9am with 30% than i put it to charge

You can either do a factory reset or NVFlash CWM and flash a ROM to see if that fixes things. If not, then defective battery.

What these guys are saying is most likely, especially with that kind of drain. But also make sure you don't have any crummy apps, it apps that run when your phones off. Ex. Some weather apps run in the background and draindrain

You guys. He said that his phone was OFF while the battery lost its juice. It has NOTHING to do with what ROM, KERNEL etc etc he is using. Now for the op; simply just get a new battery and check if the problem persists.

Try the same test with the battery completely removed.
If it doesn't drain that fast - Then the phone is not shutting down properly, and most likely is the result of a nasty app.
If it does still drain that fast - Then the battery is probably faulty.

In your original post when you said you turn the phone off at night, you do mean actually turning it off right? Like shutting it down and not just turning the screen off, right? Just making sure we're all on the same page. If the phone is powered down then it can't be an app because apps can only run when you're booted into Android.

I would try to eliminate apps one by one. Freezing them with titanium backup or using better battery stats to see which apps have a lot of wakelocks. I had the same issue before.

Then its the battery. I had the problem with my g1. I would load the maps and use gps. It would say my battery is around 70% then after like 5mins the phone would get hot and then it would say i was at 30% or lower. Swap out for a new battery and it didnt do that anymore.
My g2x is kinda doing the same thing. But its a little slower. I turn the phone on in the morning 100% battery. Then use it for about an hr. (95-80%battery) put it in my pocket. Then about 2hrs later it at 40-35%. And the phone feels warm.
Also check your battery to see if it had a lump on it. If so then its a bad battery and needs to be replaced asap.
I ordered a replacement on ebay should be here by next weekend. Only $4

Sent from my Flashback HC-TAB using XDA Forum App

I had a problem like this and still do at times. Part of it was the stock kernel I was running and the other part was the fact that the phone was not fully going into the low power state it was supposed to. I now only loose about 5 to 7% in the worst cases. That is better than the 20 to 30% I was loosing before.

Does this actually help my phone?

Has anyone tried Fast Reboot pro? I have it automatically perform a fast reboot everytime I unlock the screen, but I'm not sure if it actually does any good for my phone. Anyone that's used it before, would you mind letting me know what you think of it, thanks?

It's prob just sucking your battery dry.
Set it to do a reboot each night or something, but not when you unlock the phone!!!
It's turning a simple act of turning the phones screen on, to restarting all startup apps on the phone, not gonna be helpful.

Yeah, just use it once in a while when you phone has been running for a long time.

I use it to... But its not a task killer it just restarts apps as if it was just booted.
Like above advice just use it once in a while and make sure you check important apps in white list ir manage list under settings to prevent it to restart the launcher etc.
