I first ordered this item a first time to compensate for the very weak autonomy of the Samsung GS2. Know that my smartphone from home around 8 am 100%, I use it a lot during the day (Internet, email, facebook, games, music ...) and around 17h it has 0%. This shell allows to load about 40%: when my smartphone is about 30%, I activate the load of the shell that dies out once my smartphone is 70%. So I go home at night with a phone was half loaded, impossible before, even without using the phone, with minimum brightness, energy saver mountable to ... However, I had to return to my first Amazon hull as it had a defect that is -I think- in fact present in all preque shells (manufacturer default): When the hull as the load, it heats But if ... allowed to charge the phone until Burning Out, the bottom-right part heats too much, and -which happened to me in the first whooping, plastic hull began burned down! That is why I had to order a 2nd ... It has the same default but attenuated. Indeed, the plastic melt may légererement inside, not outside of the hull.
In summary:
THE +: this shell has great utility, it allows to save about 40% of autonomy tel BUT NO MORE (indications marked on the box are totally false!). It also protects the such, possesses a latch that folds to maintain such a way horitontale to watch a movie, for example, texture is nice. Finally, although it gets very hot, it does not damage such. So it is very convenient.
LES -: This shell is thickens, it doubles the thickness of such ... It does not last very long and very hot in your pocket ... (+ 50% GRAND GRAND max!)
Rating: 8/10
Improved: the autonomy of the hull, and its temperature too hot on!
