How to Extend Your iPhone Battery Life: Proven Tips for 2025

Nothing’s worse than your iPhone running out of power halfway through the day. Whether you’re on the latest iPhone 15 or using an older model, battery life can make or break your daily routine. Thankfully, Apple has built-in tools and settings that help you maximize iPhone battery life—and with a few smart habits, you can stretch each charge much further.

Here are the most effective strategies to keep your iPhone powered longer in 2025.

1. Turn On Low Power Mode

Low Power Mode is the simplest way to save energy. It reduces background activity, mail fetch, automatic downloads, and some visual effects. You can enable it quickly from Settings → Battery → Low Power Mode, or add it to Control Center for one-tap access.

2. Adjust Screen Brightness and Auto-Lock

The display is one of the biggest battery drainers. Lowering your brightness and enabling Auto-Brightness helps your iPhone adapt to lighting conditions automatically. Also, set your Auto-Lock to 30 seconds or 1 minute so your screen doesn’t stay on longer than needed.

3. Use Dark Mode

If your iPhone has an OLED display (iPhone X and later), Dark Mode saves energy by turning off pixels in darker areas of the screen. Not only does it look sleek, but it also improves battery performance over time.

4. Manage Background App Refresh

Go to Settings → General → Background App Refresh and turn it off for apps that don’t need constant updates. Social media apps are usually the biggest culprits here, and limiting them will instantly give you more standby time.

5. Update to the Latest iOS

Apple frequently optimizes battery performance through iOS updates. Make sure your iPhone is running the latest software under Settings → General → Software Update.

6. Limit Location Services

GPS can drain your battery quickly. Head to Settings → Privacy & Security → Location Services and change unnecessary apps to “While Using the App” or “Never.” This ensures only essential apps like Maps use your location in the background.

7. Avoid Extreme Temperatures

Apple recommends keeping your iPhone between 0°–35°C (32°–95°F). Cold or hot environments can cause your battery to drain faster or even degrade long-term performance.

8. Monitor Battery Health

In Settings → Battery → Battery Health & Charging, you can check your Maximum Capacity and enable Optimized Battery Charging. This feature reduces wear on your battery by learning your daily charging habits and slowing down charging past 80% until you need it.

9. Use Wi-Fi Over Cellular Data

Whenever possible, connect to Wi-Fi instead of cellular data. Cellular connections use more power, especially in areas with weak signals.

10. Close Power-Hungry Apps and Widgets

Widgets like weather updates and apps running AR or 3D features can drain extra energy. Keep your Home Screen clean and limit background activity for apps you rarely use.

Compact Yet Powerful – Galaxy S25 Overview

Samsung's Galaxy S25 stands out in 2025 as one of the few truly compact flagship phones—combining high-end performance, AI functionality, and premium design in a size that fits comfortably in one hand.

Hardware & Design

• Processor & Cooling
  The phone deploys the Snapdragon 8 Elite chip across all regions, a notable shift from past years. A newly-analyzed report highlights Galaxy S25 models also feature an upgraded vapor chamber—about 15% larger—to enhance thermal management during heavy usage.
• Display & Build
  Sporting a 6.2″ Dynamic LTPO AMOLED 2X display with HDR10+, 120 Hz refresh rate, and 2,600 nits peak brightness, the S25 feels bright and responsive. With flat sides, Gorilla Glass Victus 2 protection, and a slim frame (7.2 mm, 162 g), it’s classified as both refined and compact

Performance & AI Software

• Benchmarks & Speed
  Performance sees a big leap—Geekbench 6 scores for the S25 are substantially higher than earlier models, and even outperform the iPhone 16 Pro in multi-core tasks
• AI-Powered Features
  The real impact of the S25 comes from AI. Running One UI 7 atop Android 15, it includes Google’s Gemini assistant along with smart tools like Now Brief for contextual suggestions and task automations

Battery & Camera System

• Battery Life
  The S25 maintains a 4,000 mAh battery, similar to its predecessor. Still, users report about 37 hours of mixed use, with lighter, compact usage fitting every other day charging even if gaming drains it faster.
• Camera Performance
  Featuring the familiar triple-camera setup—50 MP main, 12 MP ultrawide, and 10 MP telephoto (3x)—hardware hasn’t changed much. However, better image processing now supports 10-bit HDR and cleaner low-light video.

User Feedback & Practical Experience

On Reddit, users highlight the S25’s comfortable form factor, bright display, solid camera quality, and upgraded software. However, they also note it’s more iterative than revolutionary, and its 25W charging and lack of in-box charger are drawbacks

T3’s review emphasizes that while improvements may feel modest, the compact design and strong performance make it a standout for users wanting a powerful yet pocket-friendly Android flagship.
