Many months ago, a neighbor gave me his old iPhone 3GS (32 gig) in exchange for a favor I did for him. He said he'd upgraded, it'd been sitting in a drawer for a while and he didn't need it anymore. It was dead when I brought it home, but I didn't really think anything of it as, for all I knew, they left it on when they parked it. I charged it, deleted all the personal info and set it back to "default". Well, it then sat on my desk for a few months and a month or so ago, I decided to list it on eBay. I tried to turn it on, but the battery was dead again. I thought it was a bit odd, but it had been a few months, so I charged it again and listed it. Well, the phone sold last night and as I was packaging it this morning, I noticed the battery is dead again! I really can't remember when I charged it last ... maybe a month ... maybe a bit longer ... I have no clue. My question is, should it drain in that amount of time even when turned off? Lynn and I have had iPhones since the iPhone 4, but we've never let one set that long (were always using them) so I have no clue if it's normal or not. I also have no idea how long it actually held a charge before it died as I didn't bother to check it regularly.
I'd hate to take this guys money and ship this thing if the battery is toast. I know it holds a charge (while turned off) for a few days at least, but I've never checked it after non-use for much longer than that. Any ideas? Shouldn't it hold a charge for quite a while if turned off? I need to ship this thing today. I figure if I mention any battery concerns to the buyer, it may throw up a flag and he'd find a "problem" (and possibly ask for a discount) even if there's nothing wrong with it. If I do NOT mention it, I feel like I'm being dishonest. I'll probably just charge it, ship it, and see if he has a future complaint, then handle it, but I simply don't like doing business that way. This sucks.
Any suggestions. Ya' think it's normal? I'd assume he'll keep it charged while using it, I just don't know how much talk time he'll have if it's bad (or going bad).
