It has taken a turn for the worse! Just this morning I went through 60% of the battery life from 6am, when I unplugged it from my home charger, till about 11am. That's not how she used to be. I had about 15 e-mails (On the Yahoo E-mail App), 20 text messages, Checked out FB a little on the Android App, and that was about it.
Is there an App that tracks whats using battery power?
i use system widget by jason calhoun, but all it does really is open up the battery manager so you can see whats been running. mine was acting up yesterday and i didnt get near the life i normally get. i've found that when this happens i let the battery run down until the phone shuts off. then i charge it back up and i'm back to normal. i wonder if it has something to do with the calibration getting jacked somehow.
Take a look at System Panel. It monitors what apps are running and for l how long. It will find any rogue programs that are eating your battery. Make sure to read the help file and visit the developers web site. I use it all the time, love it.
One major detractor of battery power is data flow. Like the above posters have mentioned, look at whats running. Constant updates from a dozen different feeds can cripple battery power (facebook, news, weather, sports, stocks, etc.) a large number of apps like this allow you to set the refresh rate. For example, updating a feed every minute compared to every 30 seconds should (in theory) save half the battery. Another potential is your overclock if you run one. Have you set a low idle for it? If your constantly juicing 1400 and not running at a bare minimum then it will also drop the charge on the battery. Check your settings to see what your overclock does when the screen is off. I hope that helps you.
Do you use the official Facebook app? Cause I had the same problem your describing because of the latest update for that app. It was just constantly pulling data for some reason and killing my battery. Once I uninstalled it everything went back to normal.
i have the official facebook app and haven't seen it show up in the battery usage at all.
I never saw it in the Battery Usage page either. I never knew why. Just try going without that for a while and see what happens. Its better than finding out your battery is faulty, or something of that nature.
One thing I thought of is that we've all used our Droids and charged the battery more in our Droids than any other phone, batteries only last for so long before they start losing the ability to a hold a charge for as long.
From my experience I've found that if I simply reboot the DX the battery life gets back to "normal". Seems when I let the device run for several days I begin to see battery life go crazy with major drainage. Last time I was running for 84 hours since last reboot and saw my battery life drain by 10% easily within an hour, all while sitting idle. The battery manager showed that my usage was due to "display", however the device was sitting idle with no display. After rebooting I then went the rest of the day (about 8 hours) with only 30% change in the battery.
I'm no expert and would love to understand more, but rebooting seems to solve the problem for me - just would like to know why... My guess is there is some app that's going rouge on me and not freeing up resources...
