Battery Life

I want to know which Lg mobile have the largest battery life?Also want know that When I should recharge after charging fully.

While I am not personally familiar with LG phones, I know that a battery's talk time and standby time depend on its mAh number. Standard batteries generally have 900 mAh - this number should give you around 3 hours of talk time and 45 hours of standby time. Also, Li-ion batteries (after an initial charge of 8-12 hours) prefer frequent partial discharges (letting the bars get half-way down and then charging) versus letting the battery run all the way down and then charging fully back up.

I know its not a completely updated list, but i don't have all the info for the newest phones. Sorry.

I've been testing my enV for 5 days straight with no use and it still has all 4 bars.

Update: Its now been 12 days and im down to 3 bars.

i used the music player at work the other day for 10 hours straight plus phone calls and it went down to only having 1 bar,pretty good battery life

The LX 160 for sprint has horrible battery life, It can not stay on a day without me using it.
