Who uses a Galaxy Note 1 knows how annoying is that in some cases very low battery life with constant use of the device.
So I bought this battery as a secondary battery. It was used about 3 times a week.
He has much less power than an original battery (almost halved maturities) and after about 6 months now (bought May 2013) completely broken!
(No charging possible) battery charging station no longer detects battery .....
Very sad - DO NOT BUY
