My Samsung Note 1 runs since 1 1/2 years prima, the weak points but just the battery, not surprising given the screen size. Therefore, open daily ..... Had the result that the connector port on my Smartphone was shaky and has not loaded it. A known it then repaired (soldered) .... anyway, I decided at the same time the Laderei quasi relocate "to the outside". So I have a full battery of empties slowly phone while the battery is charging 2 in this external charging station. So I change then the morning always empty to full out. The only downside, of course, settle the white plastic cover short and replace the battery, but you get used to everything ..... yes
