MacBook pro M1 13'' alway show lightning bold icon on battery
Hi guys, I'm new to MacBook and I've read some articles saying that the lightning bolt icon represents the battery being charged and the plugged-in icon means the battery is not charging and using power from the adapter (In my case Power Source is Power Adapter for both icons). But when I check it on my MacBook it's almost always showing the lightning bolt icon even when the battery is 100% and it says Fully charged and sometimes the plugged-in icon showing. I don't know if there is a problem but it seems that the Max Capacity of my device drops quite quickly (I often use the power from the adapter, rarely use the battery), my friend and I bought the device at the same time (about 5 months ago) but for now, my max capacity is 96% and my friend is 98%. Should I worry about it?
