Honor is reportedly testing a smartphone battery so large that it could last up to seven days on a single charge. According to a new leak from well-known tipster Digital Chat Station, the company is working on a battery with a capacity between 14,000mAh and 15,000mAh, and the battery has now entered trial production.
If the leak is accurate, the phone would offer by far the longest battery life ever seen on a mainstream smartphone, where even the biggest batteries today usually last two to three days at most.
What the Leak Says
Digital Chat Station shared the details in a post on Weibo, saying that a 14,000mAh to 15,000mAh battery is currently being tested and that the prototype could last for an entire week on one charge. The battery has reportedly entered trial production, which suggests development has moved beyond early lab testing.
This is not the first time such a battery has been mentioned. Reports from June 2026 also said Honor was working on a 14,000mAh battery phone, and the latest leak suggests the project is still alive and moving forward.
Some reports suggest the phone could launch sometime in 2027, although that timeline comes from the leak coverage, not from Honor itself.
What Honor Has Not Confirmed
It is important to be clear about what is still unconfirmed. Honor has not officially confirmed the device, its battery size, a model name, a launch date, or a price. The tipster also did not name a specific model, and did not say which brand the battery is for — although replies to the post and some outlets point to Honor.
Some reports mention the Honor Power3 and the Honor Win RT3 as possible candidates for the new battery, but those names are speculation from the coverage, not something the tipster or Honor has stated.
The seven-day claim itself is also unverified. It is the target the leak describes, not the result of an independent battery test, and real battery life always depends on how the phone is used, including screen time, gaming, and network conditions.
How Honor Got Here: A Battery Arms Race
The leak is believable in one sense, because Honor has been pushing phone battery sizes higher for more than a year:
- The original Honor Win, launched in December 2025, carried a 10,000mAh battery.
- The Honor Win 2, launched in China on 21 October 2026, carries a roughly 10,100mAh battery.
- The Honor Win RT 2 and Win Turbo 2, launched alongside it, carry an even larger 12,070mAh battery — the biggest Honor has shipped so far.
- The Honor X9e Pro, with an 11,000mAh battery, is claimed to last up to three days of use.
A 14,000mAh to 15,000mAh battery would be the next step in that climb, and it would more than double the capacity of most flagship phones on sale today, which usually sit between 5,000mAh and 6,000mAh.
What a Seven-Day Battery Would Mean
If a phone really lasted a full week, it would change how people use their phones. Charging would become a once-a-week task instead of a nightly one, and heavy users, travellers, and people in areas with unreliable electricity would benefit the most.
There are still open questions, though. A battery that large could make the phone thicker and heavier, and charging time, pricing, and availability outside China are all unknown. There is also no information yet about a Pakistan launch or a Pakistan price, so buyers should not expect this phone in local markets any time soon.
For now, the sensible way to read this story is as an early-stage leak about what Honor’s labs are testing — not as a confirmed product plan.

Conclusion
A phone that lasts seven days on one charge sounds like a dream, and Honor’s recent battery history shows the company is serious about pushing capacity higher. But until Honor itself announces the phone, the 14,000mAh to 15,000mAh battery and the week-long claim remain a leak — an exciting one, and worth watching, but not something to plan a purchase around just yet.
