Positives:
+ Should the cell phone battery is nearing the end of one, you can insert the additional battery and the phone is recharged during operation.
+ Through the gauge on the battery, you can always see how much energy is still available.
+ The spare battery is inserted in the iPhone down. with me (iPhone4) he raises very well so far - but should not be moved also great!
Negatives:
- The additional battery is not adapted to the iPhone4, but a bit thicker. Thus, the mobile phone is always in an inclined position when charging, which could lead to the upper connector of the battery is damaged or after a certain time could Ausleihern.
- If you protect the mobile phone by a protective cover, you can not use the battery. The phone must first be removed from the sleeve.
- Unfortunately could charge my phone in the first test (under realistic conditions) only about 3/4 back of the additional battery. I had on the phone 12% and the battery loaded the phone at about 93% - also adequate for my needs, in some but not why I want to mention it here.
Conclusion:
For those who have stayed several times in the situation that her cell phone battery did limp, the battery is a great investment. If you can live with and remove the protective cover that the mobile phone is not fully charged back to 100%, which I can really recommend this spare battery!
Recharging the battery through the iPhone charging cable works fine!
