Battery life is one of the most important factors when it comes to buying a phone. No one likes having to constantly charge their phones, especially when access to a charging brick, cable or power bank is limited. There’s also something satisfying about seeing your phone at 100%.
If battery life is a big deal to you, here is our countdown of some of the top phones with the best battery life in 2026 (updated). And yes, all these phones are available at CompAsia Malaysia.
5th place - Samsung Galaxy S23 Ultra
On paper
Non-removable 5,000 mAh Li-Ion battery
Our test
9 hours 41 minutes
Our thoughts
The S23 series has really outdone itself by extending its battery life when compared to the S22 series. The more energy efficient Snapdragon 8 Gen 2 for Samsung not only provides outstanding performance, it also assures long duration usage. The test we conducted kept the Galaxy S23 Ultra in regular performance settings, so you can expect even better battery life in energy efficient modes.
4th place - iPhone 14 Pro Max
On paper
Non-removable 4,323 mAh Li-Ion battery
Our test
9 hours 50 minutes
Our thoughts
Even with the smallest battery in this list, the iPhone 14 Pro Max outshines most flagship phones in terms of battery life. With a super powerful A16 Bionic chip that blazes through every possible task, battery life trickles impressively slowly. The only downside of the iPhone is its considerably average charging speed that stands out like a sore thumb.
3rd place - Samsung Galaxy S23+
On paper
Non-removable 4,700 mAh Li-Ion battery
Our test
10 hours 40 minutes
Our thoughts
Despite being the middle child in the S23 line-up, the Galaxy S23 offers one of the best batteries across ALL Android phones. With a 4,700 mAh battery instead of a 5,000 mAh found on the S23 Ultra, the S23+ lasts a full hour longer. This is at regular settings so you can expect perhaps over 11 hours of battery life in energy efficient modes.
4th place - Samsung Galaxy S25 Ultra
On paper
Non-removable ~5,000 mAh battery with next-gen efficiency
Our test
11 hours 10 minutes
Our thoughts
The Samsung Galaxy S25 Ultra leads the pack with exceptional battery life. Thanks to improved chipset efficiency and AI-driven power management, it comfortably lasts more than a full day on regular usage. Combined with fast charging and premium features, it’s easily one of the best battery performers in the market today.
1st place - iPhone 16 Pro Max
On paper
Enhanced battery with advanced power efficiency
Our test
10 hours 15 minutes
Our thoughts
The iPhone 16 Pro Max takes battery performance to the next level. Despite not having the biggest battery capacity on paper, Apple’s hardware-software optimisation allows it to outperform many competitors. It’s ideal for heavy users who want long-lasting performance without compromising speed.
Conclusion
Top phone manufacturers spend a lot of money on research and development to prolong battery life and speed up charging to outdo the competition. This is because phone users care about battery life despite solutions like power banks.
