Why is my Braun 9394cc Electric Shaver battery performance dropped significantly?
- VvargasstevenAug 20, 2025
A significant drop in battery performance of your Braun Electric Shaver can occur if the foil and cutter are worn, requiring more power for each shave. Renewing the Foil & Cutter cassette can resolve this issue. Also, regularly cleaning the shaver head with water but not lubricating it can cause this problem. If you clean the shaver with water, apply a drop of light machine oil on top of the foil once a week for lubrication.
