Great, let's hope it stays that way. The problem seems to be somewhat common from what I've read. I try to take care with charging it but it seems to be bend related, at least I was able to charge my phone only when it was bent a bit backwards when it was giving up.
My friend's one broke in less than a year and for some reason they were given their money back without anyone even trying to fix it.
Have you had the connector between the battery and the charging connector fail yet? If not, it might be a good idea to stock up one one. I've had to replace mine once and it might be failing again just six months later.
