My new Fit Charge 2 is losing charge much faster than the other two in our household

Both I and my wife have a Charge 2 and typically a charge easily lasts 5 days, normally more.

We bought our son a Charge 2 at Christmas and it is losing charge in as little as 2-3 days.

Also whereas mine counts down the % in blocks of charge (e.g. 70%, 60% etc.) his seems to be more particular and records drops like 67%, 59% etc)

We are all using the same features (including heart rate), we all have them on 24 hours a day, we all do around 5,000-12,000 steps a day and broadly similar exercise profile over a week.

We all have notifications on, reminders to move, always connected and we all have Motorola phones to which we tend to synch every 2-3 days.

I am seriously wondering if they downgraded the latest capacity of the Charge 2 because there seems to be no other explanation.

Or am I missing something, anybody, please?

I am off in the similar issue with my Fitbit that I've had for over a year now, is barely holding a  charge for about it and day or day and aa half now.
