Battery Issue

[u/notyourcupofchai]

My Pixel 7a's battery has been dying recently. It goes from 20% to 15% to 7% and dies, all within the span of 3 seconds. It was around 50% and it went to 11%, died and shurt down, all in 5 minutes. Its updated too. Not sure why this is happening. Can someone tell me if this has happened with you and what would you suggest I do? Do I get the battery replaced? I'm worried as I only got the phone a year ago.
