Honor Is Building a 12,000mAh Phone That Proves the Battery-vs-Thinness Tradeoff Was Always a Lie - Yanko Design

"The Energizer P18K Pop needed 18mm of thickness to reach 18,000mAh. Honor is apparently aiming for 12,000mAh in a phone you would actually want to carry. Three of the four existing 10,000mAh-class smartphones on the market already belong to Honor, with the only outsider being Vivo's Y600 Pro at 10,200mAh. The leak doesn't confirm product names, but rumors point toward the Honor X80, Honor Power 3, and a new WIN 2 series as likely homes for these big-battery ambitions."

Energizer’s P18K Pop at MWC 2019 demonstrated that lithium-ion energy density is fixed, so higher capacity requires larger size, resulting in an 18mm-thick phone with an 18,000mAh battery that was canceled before release. New silicon-carbon chemistry changes the scaling limits by enabling battery layers as thin as 0.15mm, with 32% silicon content, and delivering 6,660mAh in a slim foldable like Honor’s Magic V6. Honor is reportedly testing a 12,000mAh phone, aiming to expand its 10,000mAh-plus lineup to seven devices, with rumored models including Honor X80, Honor Power 3, and a WIN 2 series. Other brands are also working on large-capacity phones with more cautious, single-model plans.
