All the attention paid to Vivo is currently focused on its upcoming Xshot phone. That phone’s claim to fame is its camera, which Vivo claims will be among the best smartphone cameras available. However, there is another series of phones made by Vivo outside of the Xshot/Xplay line. The X line’s claim to fame was its HI-FI sound and ultra thin profile.
When the Vivo X3 launched in the second half of last year, it held the title for the world’s thinnest smartphone. Sitting at 5.75mm thin, it held the title for a little over six months before the ELIFE S5.5 came along and beat it by 0.25mm, (5.5mm) hardly noticeable, but enough to steal the crown for the world’s thinnest smartphone.
According to sources, Vivo’s Product Director, Huang Tao, has stated that the company plans to recapture the world’s thinnest smartphone crown.
The next phone in the X series (should we go ahead and call it the Vivo X4?) will use better materials he says, in order to reclaim the record. Of course, the biggest problem facing Vivo, and any smartphone manufacturer concerned with making their phone the thinnest, is battery life. A thinner phone means a smaller battery, which in turn means a shorter battery life.
Tao has a plan for this as well, it plans to utilize the latest in power-saving features. If this means something similar to the Galaxy S5’s black and white mode or simply less power hungry components remains to be seen.
How much consumers care about thinness at this point is a question that remains to be answered. Shaving a few inches off of a phone’s thickness was a big deal in the 00s, when phones were the size of small bricks, but will consumers really care about shaving off another quarter of a millimeter?Source]
