I have had an LG LX350 for about a year and lately the battery takes forever to charge and doesn't last as long as it used to. It's also been "crashing" when I use the web -- it used to reboot itself but now it just turns off and I have a hard time getting it to turn back on, regardless of how much life is left in the battery. I'm going to be upgrading pretty soon, but I was thinking about giving this phone to my son when I get my new one, so I'm wondering if it's just the battery or if the phone is on its last leg.

(I know I can take it to the store and have it checked out, but for stuff like that I usually have to leave it there all day, so I just thought I'd get some educated opinions on here first!)
