Apple has stopped telling people how long their laptops are going to last before they die.

Until this week, MacBooks have had a “time remaining” feature that estimated roughly how much charge was left in the battery, and how long that would be expected to last. But that has been removed, apparently because it was too often wrong.

Now Apple computers will only tell people how much of the battery is left as a percentage, rather than as an amount of time.

The change has come soon after the release of the new MacBook Pro, including the ones with a Touch Bar, which seem to have a more unpredictable battery life than previous MacBooks. That had drawn complaints that it was impossible to tell how long was left – and the move appears to be the result of those complaints.
