Above all, the market of small phone is not extinct. And small phone has more advantages than we may think. Now we don’t have many choices of small phone other than iPhone 5s, 6s, Xperia Compact and vkworld F1 mentioned before etc. But in 2016, if Apple releases the 4-inch iPhone, many companies would follow it and at that time we will have more choices. And the vkworld F1 might be the first one to rejoin the army of small-screen phone in 2016.
The vkworld F1 is rumored to feature a 4.5-inch 2.5D display, quad-core processor, 3.0D curved back, metal frame and a price of only $49.99.
Width under 7cm is the limit for most people to use a phone with one hand. And it is impossible to make a phone with 5.5-inch screen narrow down to 7cm. When you stand in a bus or have only one hand available, it would be hard to use your 5.5-inch phone with only one hand. But if you are using a smaller phone like iPhone 6s or vkworld F1, there will be no such problem.
Smaller phone can fit better in pocket while bigger phone often exceed the limit of most pockets. And smaller phone is easier to carry around and weighs lighter.
After Apple released its 4.7-inch and 5.5-inch iPhone, Chitika made a comparison between these two new devices in terms of traffic rate in U.S. And surprisingly, iPhone 6 accounts for 2.3% while iPhone 6 Plus only 0.3%. That means there are actually many people who prefer smaller phone. And the market need for smaller phone is still not neglectable.
Bigger screen will definitely cost more power than smaller screen. With same IPS display and same resolution and same battery capacity, a 4.5-inch screen saves more than 20% of battery power than a 5.5-inch one.
