I can t explain why we made the decision to doesnt have battery swap on TC70
but there are no way to add this by settings because it is an hardware limitation (no backup battery and no super cap)
TC75 got the supercap during alpha testing because it was a customer requirement that drove a very big project on the TC75.
Original TC7x didn't had such a feature and I don't expect to see such a change on the TC70.
If you've this as a requirement for your customers, please send additional details to the Regional Product Managers Team.
Thanks for the answers. We'll try to survive as it is. until a huge opportunity may push us to do it.
