Hard to say here because there are so many variables. My daughter has the iPhone 5 and is a HEAVY texter. Not sure how long hers lasts but I can't imagine she would be happy with that if it were true. I'd be interested to know how your current phone is working out with the same level of use.
With the same level of use, my LG Optimus G has exceeded my iPhone by miles..........on most days. Some days it likes to unlock in my pocket and go into different crap which makes the battery drain. But it's been a good experience
Got a little story now. My boyfriend has a Galaxy Note II with HORRIBLE signal issues. Problem is he bought it off ebay so there's nothing AT&T can do about it (plus he doesn't have insurance). He wants my phone so I'm willing to give it to him.......if he buys me another phone lol. So we agreed that he takes my phone, and we sell his Note so I can buy
two phones: The Blu Life Play and the Nokia Lumia 822. Sounds like a win-win to me
