Why the battery percentage on my lock screen doesn’t match the battery icon in the corner

When I’m charging my phone (iPhone 15) the percentage on my lock screen doesn’t match the percentage on the battery icon on the top left corner (for example while it’s charging on the lock screen it’s says 73% but the battery icon shows 76%)

is just a bug on the system or can I do anything to fix it?

pd: my battery health is still normal.

iPhone 15

The iPhone continuously estimates battery percentage, which may fluctuate slightly due to varying charging currents. The status bar usually displays the latest estimate, while the lock screen may delay slightly.
If your iPhone is charging heavily, like indexing photos, downloading, or updating apps, the percentage may fluctuate based on power consumption.
