I've had this battery installed for 4 weeks now in my nexus 6 and it was all working fine and a great improvement on my 4 year old nexus battery which only gave me 5-6 hours max for average usage

The battery has given the phone a new lease of life, this was a temporary measure until i could source a replacement device however it seems to be have sped up and stopped the freezing and random shut downs it started to suffer from
