In Nigeria—or any part of the world—nothing kills productivity faster than a phone that won’t go a full day on a charge (iPhone users can definitely relate). That’s why this roundup celebrates the longest-lasting battery phones of 2025—those that practically outlive their rival models. We’ve dug into lab tests, expert reviews, and real user feedback to bring you a definitive guide.
Whether you’re a heavy gamer, content creator, student, or remote worker, one of these handsets could keep you powered through marathon workdays or weeks of travel—with fewer energy worries.
1. Asus ROG phone 9 pro-champion of endurance.
The Asus Rog phone 9 Pro tops the charts, according to the tom guides battery tests, with a phenomenal 20 hours and 34 minutes of active use, which is far more than most phones can claim. Its legendary stamina is pushed by its 5,800 mAh battery, power-efficient Snapdragon 8 Elite chip and adaptive display refresh.
This is the best of the best, provided you are a gamer or heavy user and require continuous screen-on time. Also, 65W rapid charge gives you the ability to quickly recharge when required.
2. OnePlus 13: Flagship Longevity
The OnePlus 13 is directly behind Asus with approximately 19 hours and 45 minutes of battery life. With the powerful Snapdragon 8 Elite inside and a 6,000 mAh silicon-carbon battery, it was designed to perform and last.
Charging at 100W wired and 50W wireless, it is both powerful and fast–perfect when you need to get things done.
3. OnePlus 13R: Midrange Marvel
Midrange phones do not always have the best battery life, and OnePlus 13R is not an exception, scoring 18 hours and 49 minutes in the battery life tests of Toms Guide. It provides flagship-level battery life at a cheaper, more affordable price, despite having a slightly older Snapdragon 8 Gen 3.
It is a good choice when you want a combination of high endurance and low price.
4. Samsung Galaxy S25 Ultra Flagship Endurance Leader.
Samsung also has a high-end battery monster. Galaxy S25 Ultra is powered by a Snapdragon 8 Elite chip and offers about 17 hours and 14 minutes of battery life in official durations. Put in their high-quality screen, sophisticated AI capabilities and productivity features, and you have a phone that doesn’t only last long, but also delivers when you need it most.
It is the one that offers the best option when it comes to having a flagship that is not affected by staying power.
5. Apple iphone 16 pro max– best battery on an iphone.
As regards to iPhones, the iPhone 16 Pro Max is the battery life king. Their tests put it at the top of the list of the longest-lasting iPhones they have ever run a test on, and its performance exceeds many. Apple has achieved a small battery life and efficiency advantage even over phones with bigger spec sheets due to close hardware-software optimization.
When you like iOS and want a reliable companion that can be used all day, this is the iPhone to choose.
The reason battery life is more important than ever.
With power outages and commuting as a normal aspect of life in Nigeria, the ability to have one of the longest-lasting battery phones can be a game changer. It eliminates the use of portable chargers and provides you with real freedom. You can stream, navigate, work remotely, or record video content, and with these phones, you have fewer interruptions and more focus on what is important.
All these five render something different:
- ROG Phone 9 Pro – extreme durability gamer.
- OnePlus 13 / 13R-flagship or midrange battery.
- S25 Ultra – high-end experience and long battery.
- iPhone 16 Pro Max-iOS stability coupled with the leading quality of the long-term.
Final Takeaway
If battery life is your #1 priority, these are the longest-lasting battery phones of 2025 worth your attention. Choose according to your budget, platform preference (Android or iOS), and how you use your device daily:
- Need rugged uptime and quick charging? Go Asus.
- Want flagship performance without the flagship price? OnePlus 13R.
