A number beats guessing from an icon shape
The shape of a battery icon alone makes it hard to know exactly how much charge is left. Turning on the percentage display gives you a precise, at-a-glance number instead of a rough guess.
Battery habits matter over the long run
How and when you charge day to day has a bigger effect on long-term battery health than most people expect, which is worth keeping in mind alongside simply watching the percentage.
Frequently Asked Questions
I turned on the percentage but I don't see it in the status bar.
On newer models with a narrower top display area, the number shows in small text inside the battery icon itself β look closely at the icon rather than beside it.
At what percentage should I start charging?
Charging around the 20% mark rather than letting it run down to empty is generally considered better for long-term battery health, though this is general guidance rather than a strict rule.
