The Chinese company divulged the key detail via social media, which it has previously used to troll Apple as well as promote the built-in artificial intelligence capabilities of its forthcoming flagship device. The tweet was accompanied by the phrase, "#ThatFeeling when your battery lasts all day on a single charge".
With Samsung, Apple, and Google all having played their cards in the 2017 smartphone wars, Huawei is hoping to make a big splash to round off the year with its Mate 10 and Mate 10 Pro, set to be officially announced on October 16.
All indications point to both Mate 10 devices sporting a 4,000mAh battery, which would make their cell capacities larger than those of nearly all flagship smartphones to date, including the iPhone 8 Plus (2,675mAh), Galaxy S8+ (3,500mAh), Galaxy Note 8 (3,300mAh), and the Pixel 2 XL (3,550mAh).
However, it's not clear just how much extra juice beyond a day that would get Mate 10 users, given that the handset is likely to boast an energy-sapping 6.1-inch 1440 x 2880 Quad-HD AMOLED display with virtually no bezels. Having said that, the new Kirin 970 processor in the Mate 10 is supposed to be far more energy efficient, which could balance out battery performance.
As previously reported, this will be the first phone in the company's line-up to feature the Kirin 970 mobile chipset, which is based on the same 10-nanometer technology as Apple's A11 Bionic processor found in the iPhone 8 and iPhone X. It also has a built-in neural processing unit that utilizes of machine learning, making it a lot faster than a traditional processor, according to the company.
The Mate 10 Pro is thought to cost upwards of $900, with the Mate 10 price starting at $849. Both devices will likely feature Leica rear dual-lens cameras, with 64GB of internal storage and 6GB of RAM as standard. The Mate 10 series to be revealed this month is actually expected to include three smartphones, with a lower-spec device bearing the moniker Huawei Mate 10 Lite.
