Samsung Galaxy S25 Ultra vs Samsung Galaxy Z TriFold

Samsung Galaxy S25 Ultra

The 5000mAh battery paired with Snapdragon 8 Elite efficiency delivers solid all-day battery life, though charging speeds remain conservative.

• Easily lasts a full day with heavy use, and two days with moderate use
• 45W wired charging is adequate but slow compared to OnePlus and Xiaomi offerings

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
