When it comes to battery life, not all iPhones are created equal. As iOS becomes more demanding and users rely on their devices for everything from entertainment to business, battery backup is now a top priority for iPhone buyers. In 2025, the best iPhone battery models are not necessarily the newest ones — some slightly older models outperform the latest ones in real-world use. In this guide, we rank the top 10 iPhones with the best battery backup available in Bangladesh, India, and globally.

Top iPhones with Best Battery Life in 2025

Based on extensive user feedback, real-world battery tests, and Apple’s official specs, here are the top iPhones for battery performance this year:

1. iPhone 15 Plus – Up to 28 hours video playback; large 4383 mAh battery
2. iPhone 13 Pro Max – Often still outlasts newer models due to A15 efficiency
3. iPhone 14 Pro Max – 4323 mAh; strong optimization with iOS 17 and 18
4. iPhone 12 Pro Max – Excellent performance even after 4 years of use
5. iPhone 11 Pro Max – Older but very reliable; strong resale and performance
6. iPhone 14 Plus – Affordable with massive battery and lightweight design
7. iPhone 15 Pro Max – New A17 chip improves thermal efficiency and drain
8. iPhone 13 – Compact yet surprisingly efficient with A15 chip
9. iPhone SE 2022 – Smaller size, optimized with A15 Bionic (for light users)

All these models provide excellent screen-on time, standby power, and efficiency thanks to Apple’s software-hardware synergy.

Why Battery Life Matters More in 2025

With the rise of AI-driven apps, multitasking, video content, and online education, smartphones need to last longer than ever. Users are demanding full-day use from just one charge. While newer chips like the A17 Pro bring efficiency, it’s the battery capacity and software tuning that truly matter. iPhones like the 13 Pro Max and 15 Plus hit the sweet spot between raw capacity and optimization.

User Reviews: Which iPhone Really Lasts the Longest?

Thousands of user reviews on forums like Reddit, YouTube, and Apple Community consistently mention the iPhone 13 Pro Max as the battery king. In Bangladesh, many resellers confirm the same. “Most of our buyers keep asking for the iPhone 13 Pro Max specifically because of battery life,” said a seller at Gadget & Gear, Dhaka.

Meanwhile, students and freelancers prefer the iPhone 14 Plus for its lightweight build and massive battery, calling it a budget-friendly endurance device.

Comparing Battery Backup: Old vs New iPhones

It’s a myth that newer iPhones always have better batteries. While the iPhone 15 Pro Max is newer and faster, many users find the 13 Pro Max and 14 Plus offer better endurance due to larger batteries and less demanding screens. iPhone SE models remain unbeatable for light users who need pocket-sized phones with good battery.
