Docking charging issue

Hello,

I have a roborock q7 m5 plus that has worked well for the last 6 months. Lately it’s been having issues getting on the dock it aligns itself a few inches off and keeps retrying until it dies. Also the battery has been dying in 10 mins or less and the time keeps getting shorter. I have replaced the battery and same issue.

It had a similar issue a few months back where the charging ports were dirty and cleaning them fixed it. Not this time as I’ve cleaned everything and still no luck. Any other tips?

Thank you!
