My Optimus V has never had really good battery life, but I'd say it was adequate. Lately, though, it's been having an almost-daily freakout wherein the phone would heat up and the battery would discharge rapidly. I'm not sure what caused that. Anyway, I'd been becoming more and more frustrated with the Facebook app--I'd say it only worked about 10% of the time. I'd fire up the app and it would sit and load and load and load and never really get anywhere. I mostly use my phone for email, Words With Friends, texting, and FB. Hardly any phone calls. I took the advice of someone on the board and just started using the browser for FB. Why I never thought of that in the first place, is proof of what a knucklehead I can be. Anyway, since I've stopped using the FB app, I suddenly have a ton of battery life. When I plugged it in last night at 10:00 (having been on and lightly used since 8:00AM), I still had 60% charge. Normally. it would have been in the 20% range. After a couple of days of increased battery life, I uninstalled the FB app. That didn't cause any significant change. Could this just be a coincidence? It's been going on for 4 or 5 days now. Still, coincidence or not, I'm happy with the extra juice I'm getting!
