It seems simple, but itās not the norm
It may seem like a fairly obvious concession, but itās certainly not a given with rechargeable controllers and devices (DualShock 3s, Apple devices). Thankfully, Nintendo has revealed that youāll be able to use a regular olā screwdriver to remove the back of the GamePad and the Pro Controller, and replace them if you wish.
This may be a real concern at some point in your consoleās life-cycle, as Nintendo is reporting that after 500 charges, the battery level is reduced to approximately 70%. Once the Wii U launches, youāll be able to order them directly through Nintendo. There are no pricing details yet unfortunately.
The revelation also has an awesome by-product for those who play games for hours on end ā just order a spare battery and have it ready to hotswap for massive marathons!
