Hi there, thank you for sharing your experience with us. When you charge your Philips Shaver for the first time or after a very long time the battery starts charging very slowly to prevent damage to the device. Charging takes approx. 8 hours and the fully charged shaver has a shaving time of up to: 40minutes. You can also use the shaver while it is plugged-in and charging, although we advise to leave it a charge for a bit before using it, especially if the battery was completely drained out. It is possible that the performance of your shaver has declined because it is dirty. There can be hair or dirt particles stuck inside it, causing the shaving heads to don’t function correctly. To fix this problem, properly clean your shaver. If possible, remove the shaving heads and clean your shaver from the inside as well. For detailed cleaning instructions, please refer to the user manual.
