it takes me a long time to shave my head+then have to recharge is that yur experience?
Your razor sounds terrifying and or expensive.
Try a HeadBlade. Takes me about 20 minutes to shave in the shower, but I'm still new at this whole head shaving thing. No recharge time necessary.
I'm not sure of your shaving method, but I've used a Panasonic ES-LA63 for years and have never used more than 20% of the battery capacity for a shave.
How many days are you going between shave?
