Battery capacity is where the MatePad Pro 12.2 asserts a clear numerical lead, packing a 10,100 mAh cell against the iPad Air 11's 7,606 mAh — a difference of roughly 33%. All else being equal, a larger battery means more time between charges, which is a straightforward advantage for heavy users, travelers, or anyone away from an outlet for extended periods. That said, real-world battery life is also shaped by display technology, processor efficiency, and screen-on time, so the raw mAh gap does not map one-to-one to usage hours.
The more nuanced trade-off is in charging. The iPad Air supports fast charging, meaning when it does need a top-up, it gets back to usable levels significantly faster. The MatePad Pro notably lacks this feature, so despite its larger reservoir, refilling it takes longer — a meaningful inconvenience for users who rely on quick charges between uses. Neither tablet offers wireless charging, so both require a wired connection regardless.
On balance, the MatePad Pro 12.2 holds the battery edge for users who prioritize longevity and want to go as long as possible between charges. The iPad Air 11 counters with fast charging, which favors users who charge frequently and value speed of recovery over raw capacity. Which advantage matters more depends squarely on usage habits: the MatePad Pro suits endurance-first users, while the iPad Air rewards those who prefer shorter, faster top-ups.
