From premium flagships loaded with advanced features to affordable smartphones built for endurance, 2026 offers plenty of solid options for users who value long-lasting battery life.
Running out of power while paying for items, navigating with maps, or pulling up travel tickets can be incredibly frustrating. To help consumers avoid that, mobile experts at iD Mobile, working in partnership with Currys, have put together a guide highlighting the smartphones that deliver the best battery performance currently available.
Covering multiple price ranges, operating systems, and use cases, this list is designed to help users find a phone that fits both their lifestyle and power needs.
Top smartphones with the best battery life
Apple’s most powerful iPhone also leads the pack for endurance. The iPhone 16 Pro Max offers up to 33 hours of video playback, thanks to its larger battery and the highly efficient A18 Pro chip. Apple’s adaptive battery technology learns user behaviour over time, intelligently managing power consumption to maximise battery lifespan and reliability throughout the day.
For users on a budget, the Moto G04 punches well above its price point. Its 5,000mAh battery can last up to 40 hours on a single charge. A power-efficient 6.56-inch display, a lightweight Android experience, water resistance, and automatic camera enhancements all help reduce energy drain while keeping everyday performance smooth.
Samsung’s Galaxy S25 Ultra builds on the strengths of the S24 series with smarter AI-driven power management. Although it retains a 5,000mAh battery, improved background-task optimisation and the Snapdragon 8 Elite processor deliver flagship performance without sacrificing battery life — even during heavy use.
The Nothing Phone (2a) combines solid battery endurance with a minimalist, eco-conscious design. Its 5,000mAh battery handles demanding daily usage, while the signature Glyph Interface reduces unnecessary power consumption. Running Android 14 and supporting 45W fast charging, it can reach 50% in just 23 minutes.
Best known for its camera performance, the Pixel 9 Pro XL also excels in battery efficiency. Its 5,000mAh battery benefits from Google’s AI-powered background management, which automatically limits energy-hungry processes. Wireless charging support adds extra convenience for daily use.
The iPhone 16 Plus strikes a strong balance between a large display and power efficiency. With iOS 18 reducing standby drain and a 6.7-inch Super Retina XDR display optimised for performance, the phone handles gaming, streaming, and photography without excessive battery consumption.
Honor’s Magic 7 Pro is built for users who want all-day power and ultra-fast charging. Its 5,450mAh battery pairs with 100W fast charging, making it easy to top up quickly. An energy-efficient OLED display and aggressive background optimisation further extend battery life.
Offering near-flagship performance at a lower price, the Galaxy S24 FE delivers dependable endurance. Its 4,700mAh battery supports heavy daily usage, while Samsung’s One UI learns user habits to optimise power consumption. Both wired and wireless fast charging are included.
A strong contender in the budget segment, the Honor X7B features a 5,330mAh battery that easily lasts through long commutes and busy days. With 35W fast charging, users can quickly top up when needed without long charging times.
The iPhone 16e is Apple’s more affordable option in the iPhone 16 lineup, yet it still delivers reliable all-day battery life. Powered by the A17 chip and optimised by iOS 18, the phone offers improved standby efficiency and reduced idle drain — ideal for travel and daily commuting.
How to choose a phone with the best battery life
When shopping for a battery-focused smartphone, battery capacity (measured in mAh) is important — but it’s not the only factor. Display refresh rate, charging speed, processor efficiency, and software optimisation all play major roles in how long a phone lasts on a single charge.
Choosing a device that balances these elements will ensure you get the best battery performance for your specific needs and usage habits.
