What is the meaning of on AC power

Forum
iOS and iPadOS

Hello friends, I want to ask you something about charging my iPhone. When the voiceover on, and I charge my iPhone and it reach 100%, I did not unplug the charger for my iPhone for a while. Because VoiceOver said on the charging indicator that 100% battery powered charging . After 10 minutes or so, when I touch the indicator of the battery, it's said: 100% battery power on AC power. What is the difference between 100% charging and 100% on AC power? Thanks for your reply .

When it says "100% battery power, Charging", it means your phone has not charged completely to 100. Even though it might say that, it is still fully charging to 100.
However, when it says "100% battery power, on AC power", it means the battery is fully charged and that your charger may be removed.

when it says on AC power it means that the phone takes its power from the socket not from the battery and it's fully charged.

That's actually an easy one. That means the phone quit charging and is now on AC, that is alternating current, power.
