if you're buying it new, battery life can be awesome.
just remember to avoid charging it too often or when it's still pretty up and using the power safing option in the settings. disabling GPS and wifi if your outside is also helpful.
i'm on my Optimus 7 half of the day and i got 60% left when i get home after a long day.
so be optimistic, this phone is pretty big and heavy, but the battery is pretty good, the screen is clear and the glass doesn't break too easily - if you don't throw it out the window.
i dropped it like 10 times on concrete, it just got some scratches on the bottom plastics.
good choice, though it is 1st generation.
