In the quest for ultra-slim smartphones, compromises are inevitable. Apple’s upcoming iPhone 17 Air and Samsung’s Galaxy S25 Slim are rumored to feature battery capacities ranging between 3,000 mAh and 4,000 mAh, according to Digital Chat Station on Weibo. While the sleek designs may impress, the battery life is likely to disappoint.
Slim Designs, Big Compromises
The iPhone 17 Air is expected to make sacrifices for its slim form factor, including a single rear camera and a modest battery. Similarly, the Galaxy S25 Slim, while packing more cameras, also won’t be a contender for extended battery life. Both brands lag behind Chinese competitors who are adopting Silicon-Carbon battery technology for higher density and longer-lasting power.

Chinese Mid-Range Dominance
Chinese mid-range smartphones are already pushing boundaries with 7,500 mAh batteries, making the rumored capacities of these flagship devices look underwhelming by comparison. This contrast highlights the growing gap in innovation between Chinese smartphone makers and industry giants like Apple and Samsung.

Heat Dissipation and Performance Challenges
These slim designs also raise concerns about heat dissipation. Recent Geekbench results for a prototype Galaxy S25 Slim suggest potential performance struggles under heavy use.
Chinese Brands Set to Raise the Bar
The silver lining? Several Chinese smartphone makers are reportedly developing ultra-slim models with at least 5,000 mAh batteries, proving that slim doesn’t have to mean underpowered.
