How many hours of earbud battery do you actually need?
Brands now advertise 40, 60, even 100 hours. Almost none of it is per charge. Here is how to work out the only number that affects your day.
Battery is the headline number on almost every earbud listing, and it is also the most misread. The figure on the box is not the figure that affects you.
Two different numbers
Per-charge playtime is how long the buds last in your ears before you have to put them back in the case. This is typically 4 to 8 hours.
Total playtime adds the charges stored in the case. This is the big number brands advertise: 30, 42, 60 hours.
Only the first number decides whether your earbuds die during a commute. The second decides how often you plug the case in.
What per-charge figure do you need?
- 4 hours covers a normal commute each way with a top-up in between. Tight if you also want them at your desk.
- 5 to 6 hours covers a full working day of intermittent use. This is the sweet spot for most people.
- 8 hours plus matters for long-haul flights and full-day wear.
Subtract 20 to 30 percent if you run ANC constantly, because the cancelling chip draws power continuously.
What total figure do you need?
Work out your weekly listening honestly. An hour a day each way is ten hours a week.
- 30 hours total means charging the case roughly every three weeks at that rate.
- 60 hours total means about once a month.
Beyond that the returns get thin. A case with 100 hours in it is heavier and more expensive, and you will still charge it out of habit long before it empties.
The number nobody advertises
Charging speed of the case. A case that takes three hours to fill from a wall is genuinely annoying; one that takes 90 minutes over Type-C is not. This is rarely on the listing, which tells you something.
A practical rule
Buy for per-charge hours, not total hours. Then treat total hours as a convenience feature rather than a headline. Flare's 30 hours total is ample for a commuter; Bliss Buds Pro's 60 is for people who genuinely dislike charging things.
