The Mi Pad 4 Plus is a bigger version of the Mi Pad 4, as the name implies. It packs a large 10.1-inch screen with 1920 x 1200 pixel resolution, 16:10 aspect ratio and rounded corners. The design of the chassis mostly the same but weighs 485g, which is 143g more than the 8" version.
The tablet is powered by a Snapdragon 660 chipset, just like its little sibling, paired with 4GB of LPDDR4X RAM and either 64 or 128GB of internal storage. A huge 8,620 mAh battery should enable long use sessions between charges. Those won't be very fast though as the included 5V/2A charger only outputs 10W.
The Mi Pad 4 Plus borrows the camera setup from the original Mi Pad 4 - 13MP main camera on the back with f/2.0 and a 5MP one on the front with f/2.0 aperture.
The new tablet comes in only one variant - WiFi + 4G LTE while color options are Black and Gold, so the WiFi only option is reserved for the small Mi Pad 4. Anyway, the Mi Pad 4 Plus with 64GB starts at CNY 1,899 ($276) while the 128GB alteration goes for CNY 2,099 ($305). Pre-orders have already started with no word on when the actual shipments will happen.
