The Samsung Galaxy S25 Ultra comes with a 5000mAh battery that easily handles a full day of use for most people. Samsung rates it for up to 31 hours of video playback, the longest battery life of any Galaxy Ultra to date.

Daily Performance

For typical use including social media, email, web browsing, streaming, and photography, the S25 Ultra will comfortably last from morning until bedtime with charge to spare. The Snapdragon 8 Elite processor is more power-efficient than its predecessor, and the variable refresh rate display (1Hz-120Hz) adapts to save power when you don't need smooth animations.

What Drains Battery Faster

Heavy gaming is where you'll see the biggest battery impact. Graphics-intensive games like Genshin Impact, Call of Duty Mobile, or Fortnite can significantly reduce battery life. Extended video recording, especially at 8K resolution, also consumes more power.

Charging Options

• Wired charging: 45W (0-65% in about 30 minutes)
• Wireless charging: Up to 15W with Qi2 support
• Reverse wireless charging: Available for accessories

One thing worth noting: while 45W charging is respectable, some competitors now offer much faster charging speeds (80W+). Full charges take about an hour.

The Verdict

For everyday users, the S25 Ultra's battery performance is excellent. Power users and gamers may need a mid-day charge, but casual users will easily make it through a full day.
