I didn’t think it was going to be easy for any other foldable to beat the Razr Ultra 2025’s record-setting battery life performance, but it goes to show how silicon-carbon batteries are rewriting the way phones last on a single charge. After putting the latest Motorola Razr Ultra 2026 through the Tom’s Guide battery drain test, it proved to me that this new battery tech is a winning formula.
Just last week, I raved about the Razr Fold’s class-leading battery life performance among notebook-style foldables. But while it set a record, I pointed out how much better it would’ve been if it were using a carbon-silicon battery instead — something that the Razr Ultra 2026 clearly benefits from having.
