Hi, @oddjob1984, all rechargeable batteries deteriorate over time, and your Surge may be coming to the end of its life. You could try cleaning the contacts and then giving it a restart and a really good charge, but if that doesn't help, I am afraid that your best bet would be to get in touch with Fitbit Customer Support on contact.fitbit.com. Even if your Fitbit is out of warranty I know they are often able to offer loyal customers a discount on a new device. Maybe time for an upgrade? The Ionic has many of the best features of the Surge with some nice extras.
Sense, Charge 5, Inspire 2; iOS and Android
