Optics / haptics:
What has also brought me food for thought is that the cheap alternatives use only 2 of the 4 contacts.
So probably seems the functionality impaired at the cheap alternative.
The cover is on the back of brushed polycarbonate (like the original without coil).
Inside are copper contacts, a covert and invisible copper coil and two silver-plated copper plates, a large bottom and a little further up in the copper strips.
I, I find it convenient to have everything fixed directly in a back cover. The extra weight is in the hand noticeable, but in my opinion even pleasant, here, there are also other opinions.
The minimal thickness of expanded I feel the same twofold advantage.
On one hand, the device is non-slip and on the other hand is no longer out the camera lens. Since the lens protection not from scratch-resistant glass, but from ordinary Plexi-glass is, this can be quite advantageous, because fewer scratches occur.
The problem of thickness to pass close cases leads me to no devaluation, because I do not intend to use my S4 in an envelope, I find it just as it is perfect. A screen protector is sufficient and even I only plan, Weil is an anti-glare, but that does not matter here yes.
Function:
I use the Backvover with the new ZENS single charger (), which is given a rating soon from me.
Placing is very easy and the charging begins promptly at, there are no interruptions and it is also loaded to 100%.
The device heated a little more than the normal charging. The battery temperature during charging about 38, x ° C (22 ° C ambient temperature). Specifications according to CPU-Z.
The charging time is extended more accurate values in my review to the charging station, as this materially from it depends.
Conclusion:
For someone who is ready about 70 for a little 'frills' spending (and let's face it, that will still be a lot of why I buy otherwise such an expensive smartphone), extended here the functionality of its S4 noticeably.
I find it very pleasant to have to use a USB cable and the more mobile and be able to load on the writing or night on the bedside table and use this more frequently than previously expected.
A positive side effect the USB connector is used less and does not wear out.
I hope I could help them with my review and assist in their purchase decision.
