Do Belkin Docks damage internal components on the iPhone 6s Plus?

Used to have an iPhone 5s and recently upgraded to the iPhone 6s Plus. Love the screen size and especially loving the battery life however the battery life on all of my previous phones have been rubbish and wanted to know whether the belkin docks you can get online, damage the iPhone battery or charging components.

Don't want this phone to end up like the others especially as i'm a power user and the 6s Plus is handing really well at the moment.

Cheers.
