Battery doesn't keep charge [SEP] I am very disappointed with my new Philips Norelco 7110x.  Its battery is too small and requires frequent charging.  According to Philips customer service, the battery can hold a maximum charge of 25 minutes.  If it takes 5 minutes to shave....a person would need to recharge every 5 days.  This is way too frequent and a hassle.  My older Philips shaver required recharging every 3-4 weeks!  NOT every 5 days.  I'm very very disappointed with this product.
