Otherwise moin is the battery size and force to change the shell, the phone grown 1cm ... BUT! Strangely a better grip of the phone and if there are large pockets asser one notices anything. Parcontre battery is heavier than all, and no phone protective shell will go above may be anker that will one day be a special protective shell for the phone is not known
In conclusion if you want a battery that lets you use your phone a whole day without having to pay attention to the battery and if the thickness or the weight does not bother you then buy :)
