Does the 4X continued its success

Its purpose battery outstanding! Precise information at runtime increase I can not do, but the 4X now holds loosely through a day with heavy use, what about the standard battery is by far not the case.

By deeper coverage will protect the device logically considerably thicker and also, due to the larger battery, harder - for me personally no problem at all.

Negative I noticed that the battery lid is unseated particularly strong. Enough so that he does not fall off during normal operation, but should the unit, even at low altitude, fall to the ground, he would jump with safety. He also creaks slightly because of less than perfect seat if you operate the phone with one hand.

The material of the battery lid is relatively cheap plastic acting, which is slightly roughened. The adhesive properties are extremely poor, so that the risk that a device out of his hand slipping is increased, which is mitigated by the greater thickness.
