First impressions

Take JIAYU S1 in my hand, it is compact, good-looking, well-built, and powerful, which gives it an in-hand feel that's impressive in any price range. The positive impressions continue with the bright, sharp screen, rugged stainless steel, the solid build quality and nice materials are more than good enough. Battery life is good for the class, too, but we still wish the battery was user replaceable, but non removable battery was very disappointed, because sensible styling meets adequate equipment, and there's a key selling feature to nudge fence-sitters, buy or not, need some understanding and comparison, let me give u detail reviews and suggestion.

Design

JIAYU S1 looks like an amplifying version of the JIAYU-G4. The appearance of the mobile phone has little change from G2S, G4, A design concept that didn't change too much, however, if its visual appeal wasn't enough for the premium segment, and itЎЇs very well suited in the mid-range sector. I think most of people like this design and this appearance. It made entirely out of plastic with stainless steel frame. While we love metal-clad phones, and most of phones used alloy material, like JIAYU-G4 used aluminum magnesium alloy, there's nothing we didn't like about the stainless steel build of the JIAYU S1, because bring more solid protection for phones, The back cover is finished in matte plastic, which makes it virtually immune to fingerprints and provides an extra grip in hand, the back cover is non removable.

The JIAYU S1 is made entirely inside and out of stainless steel frame that's very high quality, inside and out frame made by CNC machine

The plastic is of the glossy variety that virtually immune to fingerprints and provides an extra grip in hand.

JIAYU S1 use advanced LDS Technology for GPS, WIFI, Bluetooth, and WCDMA/GSM. Laser Direct Structuring (LDS) Technology offers flexibility and geometric 3D design freedom in making antenna products beyond the previously often used flex-antenna technologies, which only allow a maximum 2.5 D design of the antenna radiator. Using a 3D laser system, LDS technology allows the transfer of the antenna design from CAD data onto a molded antenna carrier or even directly onto the device structure. Cosmetic surfaces of the antenna can also be achieved by using a subsequent spray painting process. Integrated into the whole thickness of the back cover to reduce and improve the signal strength. Laser direct molding technology, itЎЇs in the molding of the plastic bracket on the use of laser technology laser directly on the stand of forming a metal-plated antenna pattern.

SYNAPNCS Clear Pad Series 3 products are purpose-built for todayЎЇs highest performance mobile devices with up to 5Ў± displays. Trusted by top OEMs around the world, Series 3 combines the high performance and advanced features to enable the industryЎЇs most exciting mobile devices. As far as I know, MEIZU MX2, NOKIA 920 and so on used it. We feel the touch screen experience of G4 is not very good, but JIAYU S1 uses a chip (SYNAPNCS Chip which used in LG, SamsungЎ­) with a new touch to solve this problem, even across the clothes can touch.

Controls

There are three capacitive keys below the screen - Menu and Home Back- and a speaker on either side of the display, the 13MP camera with LED flash is the star of the show at the back. The camera and LED flash take the down side covered by a protective glass. There is a large logo in middle, followed by a speaker and JIAYU at the bottom.

Next to the top speaker is the front-facing camera (2MP) along with the proximity and ambient light sensors.

The right side is the Power/Lock key, the left side is the volume rocker, SIM card slot in the middle of left side, the top is 3.5mm audio jack and a second microphone for active noise, the bottom of the phone holds the main microphone along with the micro USB port.

Handling

The 5.0" display of the JIAYU S1 guarantees its also can easy handling in man hand, while the matte plastic back and stainless steel used to build the phone make it very nice to the touch. The phone's back features a slight curve, so it fits nicely in the palm of your hand. Single handed operation is very comfortable and pocket ability isn't an issue whatsoever. Overall, the JIAYU S1 is a delightful phone to handle and carry. ThatЎЇs really nice, really nice.

Comfortable single handling the JIAYU S1 is a breeze.

Display

OGS 1080P PPI440 SHARP IPS screen, the high-end market is already home to some 1080p-resolution smart phones out there; display has great viewing angles and reasonably good colors too, even more than JIAYU-G4, people who have it already knew the screen display effect is very good. OGS technology matures, touch effect becomes very good, though the display with Gorilla Glass protection, which future owners of the device also should keep in mind, because it does not resist throwing and sand friction.

OGS (One glass solution) structure: in protecting glass directly formed ITO conductive film and sensor technology. A piece of glass at the same time rise to protect glass and touch sensor dual function. from the technical aspect, OGS technology compared with current main G/G touch technology has the following advantages: simple structure, light, thin, pervious to light quality good; Due to dispense with a piece of glass substrate, and laminating process, But the technology faces induction line process selection, and do the glass surface some strength to maintain and quality stability, control chip tracking, yield ascension difficult makes less production manufacturers.

Battery life

In fact, 2300mAh is not too small, but JIAYU offer big capacity battery before, like G3, G4 3000mAh. We always forget to compare with others mobile, like iphone 5 1440mAh, GALAXY S4 2600mAh, HTC ONE 2300mAh, XIAOMI 2S 2000mAhЎ­
