Honor is reportedly testing a phone with a 15,000mAh battery and week-long life

A smartphone that lasts a week on a single charge could be in development. TechRadar, citing a leak via Notebookcheck, reports that Honor is testing an unnamed phone with a battery of between 14,000 and 15,000mAh and a guaranteed week of use

The claim comes from well known leaker Digital Chat Station on Weibo. Most phones today have batteries under 6,000mAh, Honor's Win RT 2 gaming phone has 12,070mAh, and this would be about three times the capacity of the Galaxy S26 Ultra

There are no other specifications and no launch date, and the phone may be sold only in China. TechRadar said it would not count on being able to buy it even if it launches

Potential drawbacks include extra weight and the need for complex cooling, and week long battery life would depend heavily on software tuning in Honor's MagicOS. TechRadar advised taking the leak with a pinch of salt

Silicon carbon battery technology has let Chinese phone makers fit much bigger batteries into normal sized phones, so this is plausible. A week of battery life would be a return to the days of classic Nokia phones. Many people would happily trade a little thickness for that

Would you buy a phone that lasts a week but is a bit heavier? And is battery life more important to you than other features?

There is a trade-off here that people ignore. To fit a battery that large, they likely have to compromise on the camera module or use a lower refresh rate screen. I would rather have a crisp 120Hz display and decent cameras than carry a power bank in my pocket, which is basically what this phone is.
