Has my 2015 MBAir become so slow because of almost dead battery? Debating if to replace it or not, the computer does what I need when in mobility so I'd like to keep it but it has become so damn slow and my guess is the battery being almost gone (Same issue with a 2018 model whose owner left the battery die and when I switch it on with power adapter it is slower than my racing snail...).

Personal experience with regards to this?

Grazie

It has become painfully slow, if I start on battery then attach charger it remains super sluggish, if I startup with charger it's better, before I buy a new battery I wanna make sure that's the cause, apple diagnostic doesn't show any fault but it runs on the external charger
