The mobile industry is in the midst of a major leap in battery innovation, with flagship smartphones set to feature 7,000mAh batteries as standard by the second half of 2025. According to recent rumors from China, top-tier devices powered by the MediaTek Dimensity 9500 and Snapdragon 8 Elite 2 chipsets will adopt these larger capacities—marking a significant upgrade from last year’s 6,000mAh average.
Silicon-Based Batteries Leading the Charge
A key driver behind this battery evolution is the increasing use of silicon-based batteries, particularly by Chinese smartphone brands. These batteries offer higher energy density, enabling larger capacities without adding bulk or compromising on slim designs.

Premium Devices to Push Battery Limits Even Further
Some ultra-premium smartphones are expected to go beyond the 7,000mAh threshold, reaching capacities of up to 7,500mAh. Meanwhile, mid-range devices are also joining the race, with rumors pointing to Honor’s upcoming launch of a phone packing an 8,000mAh battery—an unprecedented move for the segment.
Faster Charging to Support Bigger Batteries
To complement the massive batteries, charging speeds are also set to improve. Flagship smartphones launching in late 2025 are expected to feature:
- 100W wired charging
- 50W to 80W wireless charging
This will ensure rapid top-ups, even with significantly larger battery capacities. Although 100W fast charging is already available, it will likely become mainstream across more brands and models in 2025.
Global Divide: Chinese Brands Lead, Global Giants Lag
Despite the advancements, Chinese manufacturers are leading this battery innovation wave, while global giants like Samsung, Apple, and Google have yet to adopt silicon battery tech. As it stands, consumers may not see such battery upgrades in Galaxy, iPhone, or Pixel devices anytime soon—highlighting a growing technological divide in the smartphone industry.
