Didn't want to create a new thread, and apologies if this has been already answered, but the search doesn't show useful stuff and this thread is pretty long.
I have a (very simple?) question. One of my friends is planning to upgrade his phone, and is very much interested in the iPhone. However, he has a concern - the battery. Thing is his work requires him to handle a lot of calls. Lot as in close to 5+ hours of TALK every day. He also gets a lot of SMS - useless forwards - but doesn't use them as much. He doesn't require any other thing on the phone. Right now he carries two extra batteries with him and has been doing reasonably well.
Now he has some questions on the battery
- what options does he have when the battery on the iPhone is dying?
- what is the longevity of the battery; how many years can he expect to use the battery that comes in the phone
- how easy / hard is it to change the battery when it finishes, how much would it cost
Guys with heavy usage can probably throw in some pointers here. Thanks!
