A new 12,000 mAh battery smartphone has reportedly entered trial production, potentially setting a fresh benchmark for handset endurance. According to leaked information from a Weibo tipster, Honor has begun trial production of a battery with a rated capacity of 11,790 mAh and a typical value of 12,000 mAh.
The specific device set to house this cell has not been confirmed, though hints in discussions surrounding the leak point towards a likely candidate. Alongside the forthcoming Honor Magic 9 flagship series, the only other new model expected from the Chinese manufacturer is the Honor Win 2 series.
Which phone will get the battery
Honor has historically been conservative with its Magic series, tending to prioritise style and design over outright battery capacity. That makes the Magic 9 an unlikely home for such a large cell. The more probable option is a device from the Honor Win 2 family, potentially the Honor Win Turbo 2.
The previous two models in the lineup, the Honor Win and Honor Win Turbo, both launched in China with sizeable 10,000 mAh batteries. Reports suggest Honor had considered pushing towards a 14,000 mAh battery in future models, although firm details remain limited.
The current capacity leader is the Honor X80 Pro Max, a midrange device fitted with an 11,000 mAh battery paired with otherwise modest specifications. Should the new cell reach the Win 2 series, availability may prove restrictive, as the range is expected to launch in China and is unlikely to reach other markets in the near term.
Battery technology and rivals
Honor is currently among the leaders in silicon-carbon battery technology, which allows greater capacity within a similar physical footprint. Both Samsung and Apple have yet to introduce this technology in their flagship phones. A 12,000 mAh battery phone could offer up to three full days of use on a single charge, even without full optimisation, reducing charging to roughly twice a week.
Elsewhere, Samsung is still working towards its first devices with solid-state batteries. Current expectations point to the second half of 2027, with wearables such as the Galaxy Ring and Galaxy Watch tipped to receive the new technology first.
