Sony launched the Xperia Z4 in Japan, but the rest of the markets received it as Xperia Z3+, so there is no difference between their specs. However, compared to the Z3, we can clearly say that this new model was improved in many ways. So, if you want to know what was changed, then read this comparison.
The Xperia Z3+ “lost weight”
The Z3 came with a thickness of 7.3mm and it weighted 152grams. The Z3+ lost 8grams, but because it became slimmer at 6.9mm. However, it retained the same dimensions for the height and width: 146mm and 72mm respectively. In terms of design, we’ve noticed that the new phone is identical, featuring the familiar rectangular body made of glass and metal (with nylon corners), but the previous model was available in color options of White, Black, Copper, Silver Green and Purple, while the Z3+ ditched the last two shades and brought an aqua green color. Both phones are water and dust protected.
The display is the same
The Z3+ was rumored to support Quad HD resolution, but it’s stuck with Full HD resolution of 1920 x 1080 pixels, which results in a pixel density of 424ppi, because the screen is sized at 5.2inches. The technology is IPS LCD, but Sony added X-Reality and Live Colour LED technologies. Plus, the display is Triluminos, so you can read content in direct sunlight.
The Xperia Z3+ has a better front camera
The Z3+ came with the same 20.7MP back camera with ISO 12,800 sensitivity, LED flash, autofocus, HDR and 1/2.3” sensor size, it shoots 4K videos and supports 8x digital zoom, but the front camera was increased from 2.2MP to 5.1MP. The software was improved and received a new feature: SteadyShot, with Intelligent Active mode and Superior Auto mode.
The processor is way more powerful
Last year, Qualcomm MSM8974AC Snapdragon 801 was one of the most used chipsets on flagships, so the Xperia Z3 was no exception. The phone was powered by a quad-core 2.5GHz Krait 400 processor that was coupled with Adreno 330 graphics and 3GB of RAM and it had two variants of internal memories of 16GB and 32Gb, which allowed expansion up to 128GB.
The Xperia Z3+ came with the same RAM capacity, but it removed the 16GB variant of internal memory and it took a huge step from a 32bit quad core processor to a 64bit octa core processor (MSM8994 Snapdragon 810) which is formed by two quad core processors clocked at 1.5GHz and 2GHz. Also, the new graphics are Adreno 430.
The battery is smaller
Sony had to make some compromises and reduced the battery capacity from 3100mAh to 2900mAh, because the Xperia Z3+ is slimmer. Even so, you’ll still get a two-day battery life.
Both phones run on Android Lollipop
The Xeria Z3+ was launched with Lollipop 5.0, but the predecessor is planned to get version 5.1.
