I bought this battery for geocaching with the iPhone almost a year ago and was initially very peace, the iPhone could invite up to 3 times in constant use. Now after a year and modest use (last year about 10 times entlehrt and reloaded übern winter not in use and this year VLT. Only 5 times), the capacity dropped significantly, MAX. 1x can still invite the iPhone. The housing rattles significantly after one year (without a fall or the like just stop in my backpack) and furthermore the charging indicator does not work (just always indicates which is already fully charged, so no more red light) For me, clearly not advise as to batteries is only 1/2 year warranty and the battery after one year is virtually useless for my purposes.
