Man has indeed aware of such giants as the score 2 decided (eg I to actually have only a mobile device) - there prevails the "thickening" the overall benefit to smooth! When I use a "shelf life" of 5-7 days seems realistic, - one must also remember that when in this battery 15% called for still a capacity of not really undersized original batteries of over 30% (ie an even thirds!) is available! The battery compartment cover (the even 4 small supporting feet has!) Fits perfectly accurate, all functions are still possible, even the pen - but the high-gloss synthetic material which always looks somehow smeared, only good that's the back! So I'm very pleased insgesam! Update 25/08/13: Because actually the original battery for my use is sufficient and thereby also the possibility to use the protective cover, I had now over 6 months this battery not used. So I thought that it would be beneficial to the life, this time to use again - and there were used 98% remaining battery capacity display - as you really can not complain then about the quality!
