Something is draining my battery - Sprint HTC EVO 4G LTE

All of a sudden I'm losing battery like a champ. I unplugged my phone after fully charging it overnight, 25 minutes later with absolutely no use at all I'm at 88%. What's out there to help figure out what's draining my battery

Better Battery Stats... GSAM Battery... Etc etc... I use BBS... Just search xda and you should be able to find it, follow their instructions on how to report in their thread and I'm sure they should be able to help you, Good Luck!

Battery Readings.

I have a weird issue with my battery ..my phone will charge up to 100% but as soon as I unplug it...it takes less than 10 minutes for it to go down to 85%. Then it seems that the battery starts working normally after that...my phone is not rooted.
Any ideas or solutions?
Thanks in advance..

If you want help I suggest you provide more information. ie what rom you are running, how long you've had the phone, etc. If it is a brand new phone your battery may just need to be conditioned. Charge it to full, use it to empty, charge to full again and you should be good to go.

Its odd that a new stock phone doesn't run the battery well. in any case, the battery may not be calibrated yet. you can run this program. it will set the calibrate your battery for you. Let your phone drain down to under 15% before you recharge again. And let it fully recharge to 100%, then run it down thru the day to under 15%. After a few cycles like this, the battery will normalize. Then you will get a better idea of the battery life of your phone.

(q) very slow battery charge

Hey guys I'm getting some really slow battery charge over here. I've had my phone plugged in the OEM ac charger for over 3h now and it went from 5% to 50% and the phone is getting hot also. I haven't touched it at all for those 3h and data is off so no internet. I don't get it. It's usually fairly quick maybe 1 to 100 for about 2h.
Edit: I'm running capcomalpha with fraux kernel and stock battery.

The following suggestion may be of no help in your case, but I've experienced something like this as well, mainly with CWM that doesn't support off-charging. The phone will look like its charging but is actually drawing just enough energy to keep the phone alive. Also, the charging light will turn off after 15 mins or so. One way to ensure that your phone is getting charged adequately is to check the screen; if you see an ultra-dim screenshot of CWM then you'll have to periodically remove the charger and reinsert it "restart" the charge. Then try to boot into android to complete the charge.
The phone is on I rebooted it and it jumped from 55% to 68%

Try wiping battery stats through CWM.

buy a new battery and wall charger so you can charge the battery outside the phone.

You bumped a thread that was still on the first page after only 7 1/2 hours? Please don't do that again, not that I agree with bumping threads, but it is for when something needs brought back to the first page, not while it is on the first page.
do your have a case on? the trapped heat is cause the phone to slow down charging. it is a safety feature. off the case and flip over when charging. it should charge faster.

The phone has no case and was on the table so i guess there was nothing to make it overheat. Sorry for the bad bump i guess i was just desperate.

What version of Recovery are you on and as you said your using faux kernel. Try to revert to stock recovery or stock kernel and see if there is a change or behavior of your phone. And try aand see if fastboot is check on your power under settings..
you said it was hot. maybe you have some app in background using cpu. hence power drain and overheating.

Ok i swithed to stock kernel and its doing the same thing. I reflashed the rom and didnt install any apps to see if thats the case. I also noticed ita doing it only when the battery is low- 10% or less. Then the phone heats up and its barely charging. If its above 50% it charges fairly quckly and doesnt heat up. Ill see how stock kernel does tonight and report back.

Ok 2 days with stock kernel then a new battery then a new charger... 3h chRging and not even 10% of charge... Im cluless

[Q] Battery calibration messed up my battery

Hi.
I used Battery Calibration from google play exactly as instructed. Since then, my battery is charging REALLY slow, or not at all. When I use my fully charged galaxy after its charged overnight(connected to a charger) it shows 100%, and when I disconnect it, the battery drops... To lets say 92%. What can I do to fix this?
Thanks in advance.

Charge it till you're sure it's 100%, turn off your phone, take out the battery for a minute, put it back in and turn your phone back on.

It's not possible to 'calibrate' an SGS2 battery.
Do what Donnie suggested, and if that doesn't help, flash a kernel like Siyah which enables you to reset the fuel gauge from ExTweaks/similar app (you can do it from command line as well, if you search the Siyah discussion thread you'll probably find the exact commands).
If neither of those things work, your battery is on the way out. Buy a new one.
My battery (original) drains even wen the phone is off. First i tought that my battery was broken. I bought a new accu (original) but i got the same results. After about 8 hours ive got 15% less juice and the phone was off. What could this be?

75% it was on the whole time...even though screen was off....
This is the screenshot its a straight drop over the hours mentioned ... slope stays steady so its Constant power drain until I noticed ( you can see on the graph)
None of those apps were open, and I had done a restart right before. ( I fell asleep which is why I know I wasn't using it)

Skype and Words with Friends destroy battery life if you don't completely kill them. Show us the top of your usage stats, not the graph.

+1. Or show both. Apps that stay on data/wifi will murder battery, even on eco mode.

Right after I rooted mine I had terrible battery as well. I ended up reformatting (not wipe, actually formatting my system and caches) and then installed my rom again, fixed permissions and my battery life has been amazing. If I don't use the phone my battery maybe drains five percent all day long. If I use it a lot it will last most of the day as well.

The other thing you should check is you fast dormancy.
If you're flashing custom ROMs it's best to do it at a FULL 100% charge. In the past, before I started doing this, I had major battery life "problems." My phone would drop from 100 to 1 in a matter of hours and just hang on 1% for hours on end. If you haven't done this, download Battery Calibration, turn off your device and plug it in. Once it reaches 100%, turn the device on, run the app, and restart your device WHILE STILL PLUGGED IN. Once everything settles you should be good to go.
