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.

The Samsung Galaxy S25 Ultra features one of the most capable camera systems available in a smartphone. The quad-camera setup delivers excellent results across a wide range of shooting scenarios.

Camera System Overview

• 200MP main camera: Captures exceptional detail, bins to 12MP in low light
• 50MP ultra-wide: Great for landscapes and group shots
• 10MP telephoto: 3x optical zoom
• 50MP periscope: 5x optical zoom

Zoom Performance

The Quad Tele System provides four optical zoom levels (2x, 3x, 5x, and 10x), making it one of the most versatile zoom systems in any phone. Space Zoom extends to 100x digital, though quality is best at 30x or below.

Video Capabilities

Record in up to 8K at 30fps or 4K at 60fps. The Audio Eraser feature uses AI to remove unwanted background noise from videos. Improved Nightography helps capture clearer footage in low light.

Processing Style

Samsung's image processing produces bright, vibrant photos with boosted colors. This creates eye-catching results but may appear oversaturated to some users. The iPhone 16 Pro Max produces more natural-looking colors by comparison.

Key Strengths

• Superior zoom range compared to competitors
• Excellent low-light photography
• Versatile video recording options
• AI-enhanced features for portraits and video

Worth Knowing

The camera consistently ranks among the best in smartphone photography. For users who prioritize camera performance, the S25 Ultra delivers flagship-quality results across nearly every shooting situation.

The Samsung Galaxy S25 Ultra has an IP68 water and dust resistance rating.

What IP68 Means

• Dust: Completely sealed (rating 6)
• Water: Resistant up to 1.5 meters for 30 minutes (rating 8)

Protected Against

• Rain and splashes
• Accidental drops in sinks or toilets
• Brief freshwater submersion
• Wet hands during use

Not Protected Against

• Saltwater (corrosive)
• Chlorinated pool water (extended exposure)
• High-pressure water jets
• Hot water (hot tubs, steam)
• Depths beyond 1.5m or submersion over 30 minutes

Key Limitations

• Water damage is not covered by warranty
• Resistance decreases as seals age
• Physical damage can compromise seals
• Avoid charging while wet

If Water Exposure Occurs

1. Remove from water immediately
2. Wipe dry with soft cloth
3. Air dry completely (avoid hair dryers)
4. Wait for USB-C port to dry before charging

Summary

IP68 provides good protection against accidental water exposure. However, the phone is water-resistant rather than waterproof. Avoid intentional submersion or harsh water conditions.
