Longest Lasting Phones 2026
Best Samsung battery balance
Samsung Galaxy S26+
The Galaxy S26+ pairs a 4,900mAh cell with a 6.7-inch display. The S26 Ultra has a slightly larger 5,000mAh cell, but its larger 6.9-inch screen means capacity alone does not decide real-world endurance.
The A35's 5,000mAh battery combined with its efficient display makes it one of the longest-lasting budget phones available. Easily gets through a full day.
The iPhone 17 Pro Max is Apple's best battery phone, consistently outperforming smaller iPhones thanks to its larger battery and efficient A19 Pro chip.
The Samsung Galaxy A35 and OnePlus 12R are among the longest-lasting phones. The A35 is especially impressive for its price.
How many mAh is good for a phone battery?
4,500mAh or more is good for all-day battery life. 5,000mAh is excellent. Actual usage also depends heavily on the phone's chipset efficiency.
Do iPhones have good battery life?
Modern iPhones have significantly improved battery life. The iPhone 17 Pro Max is particularly strong, though Android phones often offer larger batteries.
Is fast charging bad for battery health?
Modern fast charging is designed to be safe and minimises long-term degradation. Charging to 80% rather than 100% is the best habit for long-term battery health.
