Average number of flights or total flight time vs Battery Life

Just like your favorite laptop... A battery may last a year, and another can still be happy after 4... it's often a bit of a lottery.
I'd expect a couple of hundred cycles if treated well.

The "battery life" is displayed in the batery info page and it's reported in %, i.e. how much of the original capacity it still has. It's not "black or white",it will just gradually decrease with age/cycles. When it's not enough for you anymore will be your own call.
 
Read your reply last week. Thanks for the info. A year sounds better than three or four months. Plan on buying extra batteries anyway for the short flight time.
 
I got mine new and it started at 98%.... That kinda sucks... Anyone else in the same boat?
