the device fit very well on the smartphone. the buttons on volume and on block are a little heavy to activate. the weight is more heavy than normal. but the power supply is insuperabile.
easured capacity by 5W light bulb : 6058mAh 29310mWh. Well cover the phone Buttons work correctly Quite thick and heavy but acceptable for use. When charging First phone is loaded then case Holding the button down to choose what to charge DOES NOT WORK . When charging the case The telephone is maintained at 100% wich is bad for battery But this is best battery case I bought on Aliexpres The rest is worst I have 4 more :)
