Since yesterday, my mac is showing a cross in battery icon in menu bar.
I'm unable to boot it up after shutting down without plugging in the charger. On removing charger, battery in system preferences shows battery health as normal and current charge as 1% but I'm still able to use it for pretty long.
After multiple reboots yesterday, the problem was fixed for once and I was able to see correct battery percentage but the problem came up again today after booting it up from shutdown state. I don't understand the issue and don't seem to find similar issues with M1 chips online. There are some issues with Intel Chip, but they suggest to reset SMC. For M1, it was suggested to restart but it doesn't seem to work.
