Samsung Galaxy Z TriFold vs Xiaomi 15

Samsung Galaxy Z TriFold

The 5,600mAh battery is the largest Samsung has ever put in a phone, and it needs to be — powering a 10-inch display is demanding. Most reviewers report adequate but not exceptional battery life.

• 5,600mAh battery manages a full day for most users, even with regular use of the unfolded display
• Using primarily the front screen extends battery life significantly — smart usage habits are rewarded
• Extended tablet-mode sessions can drain the battery rapidly — the 10-inch display is power-hungry
• 45W charging helps recover quickly, and you'll want it — heavy users will need a mid-day top-up

Xiaomi 15

A standout category for the Xiaomi 15. The 5,400mAh silicon-carbon battery is a huge upgrade from the Xiaomi 14's 4,610mAh, delivering 16+ hours of active use in GSMArena's tests and consistently 7-8 hours of screen-on time. 90W wired charging goes from 0-100% in about 50 minutes.

• GSMArena Active Use Score of 16:28 hours — excellent endurance for a compact flagship
