Wireless Internet Hotspot for Tablet, navigation, games and normal use in one day, the whole day and I close the phone the evening with 40% again in the charging cable. If the battery pack you insert the first time, indicates the smartphone, it is 100% charged, the course is not true. Simply play empty and then again charge completely, then you have 100% charge. (Only vozubeugen misunderstandings) Conclusion: works just fine and long.
