So I have had my X since 7/20. I have the OTA update. I was reading the X owner's manual and came across recommendations from Motorola to perform a soft reset (i.e. power off and restart) once a day to clear the cache or something like that. I think it was listed under tips to keep phone performance speedy. I have been doing this when i remember, maybe 2 or 3 times a week. The last few days, I noticed my phone had considerably more battery life when I got home from work. I have "smart mode" battery profile. No task killer. Right now I am at 90% battery level, 5 h 40 min since unplugged. I had bluetooth on about an hour, wifi off whole time, about 5 min phone calls and about 10 texts. I have checked e-mail a few times. Pretty light use but I have been busy at work this morning. Anyone else notice improved battery life 2 weeks out?
