By the time I had purchased my LG I had heard about the short battery life so I just got the double battery as my default batter. with the special cover to accommodate the battery's size, it's a little bulky, but worth it.
Note: my phone rebooted for no reason last night a couple of times, and I left it charging over night, and though plugged in, it does not appear to have charged, nor to be charging,. the percentages are appearing to stay close to the same (11%) but the flashing "battery charging' icon is doing it's thing.
Does this sound familiar to anyone?
EDIT:
Ok. it's recharging after all, just REALLY SLOWLY. from 11% to 12% took 20 minutes[/
Here is my take I have the Verizon extended battery yesterday I got 18 hours out of that battery with medium use no games just web browsing some phone calls and texts and that was under wifi and under 4g, I noticed today that I was at 30% left and I change launchers and rebooted and when it came back from reboot it was down to 21% which was weird don't know if anyone else has had this issue but I find it weird I also have Kanaida app, but have not try it I just don't know how some people in here have gotten like 15 hours with a regular battery I mean an extended battery is suppose to give me double and that is what I have notice.
