How to Extend iPhone Battery Life: Expert Advice

If there’s one thing all iPhone users can agree on, it’s the need for longer battery life. Whether you’re on the latest iPhone 15 Pro Max or an older iPhone XR, maximizing battery performance is crucial in today’s mobile-first world. This article delivers expert-backed, practical strategies for effective iPhone Battery Saving in 2025, helping your device last all day—and then some.

iPhone Battery Saving: Core Strategies That Work

The iPhone Battery Saving tricks listed here are based on iOS 18’s newest tools and long-term power management features. Start with these basics:

• App Hibernate: Go to Settings > Battery > App Usage and disable or hibernate rarely used apps.
• Low Power Mode Automation: In Shortcuts, create an automation that activates Low Power Mode at 30% battery or during travel.
• Disable Background App Refresh: Save 10–15% battery daily by disabling it under Settings > General.
• Screen Brightness: Set to manual. Keep it at 50–60% unless outdoors.
• Dark Mode Always On: OLED screens save battery by using less power for black pixels.

Implementing just 3 of these habits can extend daily battery by 2–4 hours on most models.

New iOS 18 Battery Features in 2025

Apple’s iOS 18 introduced key tools aimed at battery optimization:

• Battery Health Smart Tips: Recommends personalized suggestions based on your usage.
• Optimized Charging for Multiple Locations: Learns your work and home patterns for smarter charging.
• Battery Usage History Graphs: Now shows 7-day and 30-day trends for better insights.

These tools are found under Settings > Battery and help prevent long-term battery degradation.

Pro Settings and Lesser-Known Tweaks

• Turn Off System Haptics: Settings > Sounds & Haptics > System Haptics
• Use Wi-Fi over Mobile Data: Wi-Fi is always more energy-efficient
• Limit Location Services: Set non-essential apps to “While Using” or “Never” under Privacy

Reducing these background processes significantly lowers battery drain.

How to Charge Properly for Battery Longevity

Many users unknowingly shorten battery health by poor charging habits. Here’s how to do it right:

• Don’t charge to 100% daily: 80–85% is ideal
• Don’t let battery fall below 15% regularly
• Use original or MFi-certified chargers only
• Enable Optimized Battery Charging in Settings > Battery > Battery Health

These techniques reduce battery wear and maintain performance longer.
