The OnePlus 15 leads because it combines the highest battery score (95) with a flagship processor and fast charging, giving the longest real‑world endurance.

Picks weigh five capabilities against the price, not the battery rating alone. How we rank →

The Redmi K100 Pro follows closely with a battery score of 93, a massive 8,580 mAh battery and 100 W charging, giving you the longest endurance among in‑budget phones.

The Honor 600 Pro offers a solid 7,000 mAh battery with a score of 58 and a Snapdragon 8 Elite chip, giving good endurance and flagship performance.

With a 6,210 mAh cell and a battery score of 53, the Nubia Neo 5 GT gives decent endurance, though its camera lacks OIS and the brand’s service record is weak.

The S25 Ultra’s 5,000 mAh battery scores 38, lower than the previous picks, but the phone excels in camera (9. 5), software support and resale value.

The iPhone 17e gives a battery score of 29 with a 4,005 mAh cell, but iOS’s efficiency and the brand’s resale value make it a viable alternative if you prefer iOS.
