Sony has a line of phones called Xperia Ace that are only sold in Japan. The Ace III is the latest addition to this line. Now, Sumaho Digest is talking about the next model, which will probably come out sometime next year, and giving some details about it (the info originally comes from Weibo sources).
The Sony Xperia Ace IV will still have a small 5.5-inch screen, but it will have a better OLED panel with a resolution of 1,080 x 2,520px. The Mark 3 had an LCD with a resolution of HD+. The new generation will switch from the 19:9 ratio to the 21:9 ratio that is the Sony standard.
The Snapdragon 4 Gen 1 chipset will give the phone greater computational muscle; while it won't be a speed demon, it should be noticeably quicker than the Snapdragon 480 utilized in the Mark 3. This 6nm chip has similar performance to the Snapdragon 695, according to AnTuTu benchmarks (which powers the Xperia 10 IV).
According to rumors, the CPU will be accompanied with 6GB of RAM and 128GB of storage (an increase from the current 4GB of RAM and 64GB of storage). Convention dictates that a microSD card slot be included in mobile devices, thus this one should as well. Like any respectable Xperia, it ought to be resistant to moisture and equipped with a 3.5mm headphone port.
However, it appears that the battery capacity of 4,500mAh and the charging power of 18W will remain same. Considering how much smaller this phone is compared to other Androids on the market, that's still more than enough.
As we've already established, the first three iterations of the Xperia Ace have only been available in Japan. The Xperia Ace IV has not yet been released in all markets, however there have been recent rumblings that Sony is considering expanding the device's availability.
