What you need to know

  • Rumors from overseas claim Honor is working on a phone battery between 14,000 and 15,000mAh.
  • The tipster claims the Chinese OEM is already testing such a battery, and its main feature could be its "guaranteed" ability to last a full week on a single charge.
  • Honor stepped down a battery-focused route in 2025, stating it would increase its phone battery capacities with silicon-carbon tech.

Word is that Honor is working on a phone with a huge battery that's also incredibly efficient.

Earlier this week, Digital Chat Station (DCS) posted a few supposed details on Weibo about a future Honor phone's battery (via Android Headlines). According to the tipster, Honor is developing a phone battery between 14,000 and 15,000mAh. DCS states the Chinese OEM is currently "testing" a battery with such an increased capacity. However, it looks like Honor is also trying to ensure the battery remains efficient with low user demand.

Rumors add that this battery could be "guaranteed" to last a full week on a single charge. DCS states this could be the "main feature" of the phone's battery. The tipster replied to user comments, adding that the device (and likely the battery) won't be overly large. So, there's a chance Honor is working on upgrading its silicon-carbon battery technology even further than what we've experienced.

As if it needed to be said, these totals are massive. It feels like Honor wants to place a mini power bank inside a phone. Recently, the company debuted the Magic 9 Pro Max. It marked the start of Honor's shift toward a more cinematic approach with its ARRI partnership. Aside from that, the phone features an 8,800mAh silicon-carbon battery. Honor's been increasing its battery capacities over the years, and this phone is no exception.

The company states the Magic 9 Pro Max supports 100W wired SuperCharging and 80W wireless charging. These have been classics for it over the past few launches, and if this rumor is true, we might expect more of this.

Honor has huge battery plans

A year ago, Honor detailed a stronger focus on phone batteries. We've seen much of this thus far. At the time, the company said it was developing 7,020mAh-7,200mAh batteries for its flagships; however, we've seen that pushed to over 8,000mAh with the Magic 9 Pro Max. Even the company's mid-ranges were said to find a place between 8,200mAh-8,400mAh.

All of this comes off the back of its silicon-carbon tech. We reviewed these details, discovering that Honor's tech will have "higher density." In short, it keeps the hardware smaller (thinner) while increasing its total capacity. It's a great way to not make overly bulky phones, but still make good on what consumers want: bigger batteries. The folks at Android Headlines reminded us of another Honor device: the Win RT 2 gaming phone. That phone offers a 12,070mAh battery. Hearing this rumor that pushes things to 15,000mAh at the highest, maybe it's not too far-fetched.
