No recent changes, other than the inevitable updates to existing apps, have been made to my Droid X. The battery used to last about 2 days. This has suddenly decreased to about 6 hours. The battery usage is not showing any app using much battery power. I tried a second battery, a thick 3500mAh battery and it also runs down WAY to fast. (I charged it up with an external charger before using it.) There was a similar post from Kmoenck ("Battery draining faster than it used to. ") but he has a different phone and the solution that worked for him is not applicable to my phone. Meter training was also suggested to him. 3 Questions: 1. Should I try meter training? 2. If so, is the procedure the same for my phone? 3. Anything else I should try? Thanks for your help!!
