Smartphones with Upto 20 hour battery: Buying a phone with amazing battery life doesn’t equal compromising on poor features anymore. In 2025, a number of smartphones have amazing endurance to go alongside high-end features, powerful chipsets, bright displays, and even AI features. For gaming, browsing, or streaming, these phones are made to last for hours — some even more than 20 hours. Here’s a glance at the longest-lasting smartphones this year.

Asus ROG Phone 9 Pro

Asus raises the bar with the ROG Phone 9 Pro, which beats everyone else when it comes to battery life with a whopping 20 hours and 34 minutes. Backed by a 5,800 mAh battery and power-saving Snapdragon 8 Elite chipset, it is able to provide multi-day use. Despite keeping the screen capped at 165Hz, it still beats most competitors. Charging is quick too — 74% in just 30 minutes with a 65W charger — making it ideal for heavy users and gamers alike.

OnePlus 13

OnePlus 13 almost makes it to 20 hours, clocking in at 19 hours and 45 minutes. Its 6,000 mAh battery and Snapdragon 8 Elite processor have a lot to do with it. The phone also features super-fast charging — 80W in the U.S. — reaching 92% within 30 minutes. With 50W wireless charging support, OnePlus 13 is a solid all-rounder for users who appreciate pace and longevity.

OnePlus 13R

OnePlus 13R demonstrates that a flagship isn’t required to have enduring battery life. Borrowing the same 6,000 mAh battery as its brother and the aging but powerful Snapdragon 8 Gen 3 processor, the 13R runs for 18 hours and 49 minutes. Wireless charging is absent, but 80W wired charging is present, and 60% in half an hour is achieved. It’s a good choice for those looking for wallet-friendliness without skimping on battery longevity.

Asus ROG Phone 8 Pro

Asus ROG Phone 8 Pro follows the brand’s tradition of long-endurance battery life, with a score of 18 hours and 48 minutes. Although replaced by the ROG Phone 9 Pro, this phone remains solid with the same 65W fast charging and a smaller battery. It’s still an excellent choice for users who need constant performance without the need for constant recharging.

Moto G 2025

The Moto G 2025 shows that battery life can be long even without a premium phone. It has a 5,000 mAh battery and lasts 18 hours and 32 minutes on tests. Motorola’s optimized software and intelligent refresh rate management keep power consumption going longer. It’s one of the best budget phones of 2025 when it comes to battery life.
