As an alternative I bought these two and used to start optimally according to instructions. Unfortunately, the two could not be loaded for a time. For this reason I have turned me to anchor this and sent me in a very short time two new. This work now for over a year in my note properly and not cause any problems.
The duration of a battery is limited in normal operation in one day. Depending on the number of open apps or performance Eating (Games, background apps, and so on) the battery lasts depending on usage. So always nice to know what the phone makes in the background and how you use it. ;)
Thus, there are five stars for the battery and the anchor support :)
