Help my battery died overnight

[nguyen18]

Last night my battery was at 90% then I woke up in the morning to discover that it had dropped to below 10%. This is my second night with this htc thunderbolt and the only thing that I did different was that I turned off my network and WiFi. I assumed that it would save battery since it wouldn't run. Is that the possible cause of my drained battery?

Check for backgrounding apps! like battery widgets or your weather/mail/ what ever service automatically refreshes. If not hold the power button down and reset the phone. Tell me how this works!

Mine died the first night because I left my Wifi on and didn't plug in when I went to bed. Is your bluetooth turned off? The phone will eat up juice searching for a device to connect to. Make sure that your screen timeout is not set to "never"?

My Palm Pre would routinely shut down overnight if I didn't plug it in. I don't think this is unusual - especially for a phone on LTE and running widgets.

I have GPS, BlueTooth, and WiFi turned off. I also set my brightness down to the lowest option. Make sure you use something like advanced task killer to kill everything that is running before you go to sleep. Between those things and having screen timeout set up my battery life was 16 hours yesterday before I hit 10%

You have a rogue app check your battery awake time if its close to the same as your up time. There is a bad app keeping it awake. Tango and yahoo messanger are probably the culprit if you've got em

Make sure you close all apps completly- apps like Angry Birds do not close themselves if you just go out of them by hitting the home button. Best practice is to hit back button until you are sure it is closed.
Also some live wallpapers downloaded from the market may eat up your battery. Some do not let your phone go to sleep.

That happened to me on my OG Droid and I've been an overnight charger ever since. I can't have my alarm turning off on me.

sigh... few points

1)Say no to task killers, "running" apps that you aren't using are automatically suspended by the OS. You don't have to manually close anything.
2)wifi uses less power than mobile data, if you're at home in range of wifi. Personally I keep both off, if I need internet and I'm at home or work, I turn on wifi, if not I turn on 3g(mobile data)



That said 80% drain overnight idling means something's wrong. Unless you had 4g turned on the whole time, there is a bad app.

Download Spare Parts from the market. Install and run. Click battery history, and then change other usage to partial wake usage. If anything is taking up a large amount, that app isn't allowing your phone to idle, or sleep.
