Charge 5 battery is draining too quickly

[Mojoscunny]

My Charge 5 has got very temperamental recently. The battery drains from 30 percent to 10 percent in seconds and it turns itself off if I do any strenuous exercise meaning that half my steps aren't counted! I did the last update thinking that was the problem but it's still as bad if not worse. Is it the dreaded end of guarantee period disease??

As of yesterday my Fitbit stopped holding its charge. Tried contacting customer support and they were useless and clearly didn't know what they were talking about.
