Number of steps jumps dramatically

[Cacti]

I go for a walk and the Fitbit Zip syncs when I get home. So far, so good. Then I pick up the Zip and walk to the kitchen and back to the bedroom and the mileage and number of steps have jumped dramatically. What gives?

A warm welcome to our new friend @Cacti! That definitely sounds pretty weird and by what you are describing, it could be that the side spring may be bent as a result of improper battery insertion or pressure being applied to the back housing. Please verify that there is proper contact between the battery and the battery contacts inside your Zip tracker. 

You can do this by opening the battery door of your Zip, removing your battery, and ensuring that the silver battery tab located in the lower right half of your tracker is flush with the white box outline in the tracker housing. The process can be followed here. Good luck and keep me posted with the outcome!
