Huawei’s Mate 70 Air has drawn attention for its battery performance, reportedly outperforming Samsung’s Galaxy S25 Edge and Apple’s iPhone Air despite having a similarly slim design.
While many smartphone makers reduce battery size to achieve thinner devices, Huawei appears to have taken a different approach. The Mate 70 Air is slightly thicker than some rivals but offers a much larger battery, focusing on longer battery life rather than extreme slimness.
Battery Size Sets Huawei Apart
Battery life remains a key concern for smartphone users. Although Samsung and Apple continue to improve performance and features, battery capacity has been a long-standing limitation, especially in slim flagship models.
For comparison:
- iPhone Air-class devices typically use batteries under 5,000mAh
- Galaxy S25 Edge is also expected to stay around the same range
- Even flagship models like the iPhone Pro Max and Galaxy S Ultra offer batteries below 5,100mAh
Slim designs often limit internal space, forcing manufacturers to compromise on battery size or other components.
Huawei’s Silicon-Carbon Battery Technology
Huawei claims to have overcome this challenge with new battery technology. The Mate 70 Air uses a 6,500mAh ultra-thin silicon-carbon anode battery, which allows higher energy density without significantly increasing thickness.
This enables the phone to deliver longer battery life while maintaining a slim profile.
Fast Charging Support
In addition to its large battery, the Mate 70 Air supports:
- 66W wired fast charging
This allows the device to recharge quickly, reducing downtime during gaming, video streaming, or daily use.
A Different Design Philosophy
Huawei’s approach highlights a growing divide in smartphone design strategies. While some brands prioritise thinness above all else, Huawei appears to be focusing on balancing slim design with practical battery capacity.
The Mate 70 Air offers users a choice between extreme thinness and longer-lasting performance, positioning battery life as a key selling point.
What It Means for the Market
The Mate 70 Air suggests that larger batteries in slim smartphones are still possible with advances in battery technology. As competition intensifies, pressure may grow on other manufacturers to rethink battery compromises in future devices.
