This unnamed phone (translated source) is likely a result of new strategies that are being developed to combat the limits of silicon batteries. While 7,500 mAh batteries are becoming more common, phone manufacturers want to see just how far they can push these new cells.
Recently, the Honor Power debuted with a large 8,000 mAh battery, and the company has already released a new phone with a battery capacity of 8,300 mAh. From a purely numerical perspective, Apple and Samsung have fallen extremely far behind. The idea of an iPhone or Galaxy flagship with a 10,000 mAh battery, let alone an 8,000 mAh battery, is a pipe dream.
However, there is a lot more to batteries than you might initially assume, especially when it comes to silicon batteries. A 10,000 mAh phone that’s slimmer than 8.5 mm sounds excellent, and it is, but it won’t last nearly as long as your iPhone 16, Google Pixel 9, or Samsung Galaxy S25.

Samsung just announced the Galaxy Z Fold 7, and it keeps the same battery that the Fold 6 had, with a capacity of 4,400 mAh. In my opinion, the Fold 7’s battery is pretty good. It’s not mind-blowing, but it will be working at much better capacity after a couple thousand charges than its silicon rivals.
If you change phones often, then silicon batteries are definitely a more enticing option. And a slim phone with a 10,000 mAh battery sounds like a dream come true. Especially if you’re against Apple and Samsung’s recent approach with the Galaxy S25 Edge and the iPhone 17 Air, which sacrifice battery life for aesthetics.
