Powerful flip phone battery put to the test: How long does it last?

Motorola has equipped the Motorola Razr Ultra 2026 (Razr 70 Ultra) (approximately US$ 1,500 on amazon.com) with a larger battery capacity of 5,000 milliampere-hours. This makes the battery slightly more powerful than in previous generations.

Comparable battery capacities on the market

The Razr 60 Ultra offers 4,700 milliampere-hours, which is 300 less than the current model. The Xiaomi Mix Flip 2 comes in at 5,165 milliampere-hours and is slightly ahead. Samsung’s Galaxy Z Flip7, on the other hand, has only 4,300 milliampere-hours. Motorola thus positions itself solidly in the upper tier in terms of battery capacity.

Power consumption measured under load

In idle mode—that is, under light load—the device consumes up to 1.6 watts, which is quite high compared to others in its class. Nevertheless, it delivers respectable battery life of up to 16 hours and 14 minutes in our Wi-Fi Web browsing test.

Everyday scenario: Commuting and office work

For regular train commutes and office use, the battery typically lasts a full day. Navigation apps and video conferences, of course, drain the battery more than just reading.

Business professionals who don’t charge their devices daily should plan to carry a power bank as a backup.

Gaming performance vs. power consumption

The SoC is powerful, which can take a toll on battery life when gaming: While power consumption during gaming sessions is acceptable, heavy gamers should still keep an eye out for a nearby outlet.

Motorola’s battery strategy shows progress, even with its foldables. However, the Motorola Razr Ultra 2026 can’t quite keep up with the competition just yet.
