Top phones of 2025: Battery life | Infinium-tech

The biggest battleground in the smartphone world this year was the battery. The widespread adoption of Si/C (silicon-carbon) batteries was particularly noticeable this year, with some manufacturers stuffing 7,000+ mAh capacities into regular smartphones.

In fact our all-time battery life ranking is now dominated by models released this year. All reviews except iPhone 16 Plus are scheduled for 2025.

Many handsets broke 20h active usage score Barrier, OnePlus 15 tops the chart with a score of 23:07 hours. Its close sibling, the Oppo Find

An interesting trend is that almost all the phones on this list are flagship phones, which wasn’t always the case. This can be easily explained by the fact that the price of Si/C batteries is still high, so they have not yet fallen down in the ranking.

Even though the Honor Magic 8 Lite and iPhone 17 Pro Max may not make our top 10 of all-time, they are at number 10 in 2025.

If you came here for some specific recommendations, here are some.

Those who care most about call time should consider the Realme GT 8 Pro or iQOO 15. The Xiaomi 17 Pro Max also performed well in our call tests.

For browsing, the Find X9 Pro, iQOO 15 and Realme GT 7 posted the highest runtimes.

For video playback, the iQOO 15 is the undisputed champion, but the GT8 Pro, Xiaomi 17 Pro Max and Find X9 Pro also put up impressive numbers.

The Nubia Z80 Ultra and Nubia RedMagic 11 Pro, along with the Poco F8 Ultra, deserve an honorable mention as they perform equally well in all categories, placing 7th, 8th and 9th with overall excellent active usage scores.

Expectations are that 2026 will see even larger battery capacities, and they will also be found in more budget-oriented and mid-range phones. Really good times!
