But after 3 months you could see a drop in performance. The battery was empty after a week and if you Telephoned was once more out of battery on the same day. After 5 months, the battery lasted just one day. I have reported this to the dealer and also got compensation. However, this replacement held just 2 months and then scrap the battery was just like the others.
So stay away from the cheap crap. The original batteries by AVM are not expensive and also keep long. My battery AVM is now a year in phone and so far no problems.
There are only two stars because the battery has been replaced without problems at once the new battery was actually already there, because I have the old is not even sent. The battery view would not even get me a star.
