Foldable phones are entering a new stage. On April 29, 2026, Motorola introduced three new Razr flip phones, and one of the clearest messages was battery life. Motorola says the new Razr Ultra has a 5,000mAh silicon-carbon battery, the largest in any flip phone sold in North America, with 68W fast charging. Even the lower models now stress endurance: the new Razr has a 4,800mAh battery, while the Razr+ has 4,500mAh. (prnewswire.com)
This shift did not start in 2026. In April 2025, Motorola had already pushed the category forward with the Razr Ultra’s 4,700mAh battery and 68W charging, while the regular Razr offered 4,500mAh. Motorola also highlighted a titanium-reinforced hinge, support for more folds than the previous generation, and IP48 protection, showing that “lasting longer” meant durability as well as battery life.

Rivals have clearly moved in the same direction. Samsung unveiled the Galaxy Z Flip7 on July 9, 2025, with a 4,300mAh battery, the largest ever in the Galaxy Z Flip line, and Samsung says it supports up to 31 hours of video playback. Outside the flip-phone segment, OPPO’s Find N5, launched globally on February 20, 2025, raised the bar for book-style foldables with a 5,600mAh battery and a claim of “the best battery life of any folding phone.” (news.samsung.com)
The meaning of this competition is simple. Foldable phones are no longer trying to win only with a cool shape or a nostalgic name. Companies are now fighting to prove that a foldable can stay thin, survive daily use, and still last all day without making users worry about the battery. That is a big change, and it may be exactly what foldables need to move from eye-catching gadgets to truly practical everyday phones. This is an inference based on the direction of recent launches and official product claims. (prnewswire.com)
