Battery life sucked. Drained extra fast.
Got hung up with the tab that connects the battery to the connecter. There was no instruction that for the back to fit, it needs to be folded down so it sits between battery and connecter.
Once If figured that out, it fit back to together nicely.
Battery life is like new now.
Get someone with small fingers to work on these! =)
