A post from a Microsoft rep on the company's support forums says that reports about some Surface Pro 3 tablets experiencing issues with fast battery draining could be fixed with a software patch.

Surface Pro 3

Earlier this month, many Surface Pro 3 owners began reporting online that their tablet's battery were experiencing a reduction in its charge. Microsoft support rep Greg posted a statement on the company's support forums that finally offers some hope this issue could be fixed without a hardware switch:

We are aware of some customers reporting a scenario with their Surface Pro 3 batteries in which the system is reporting lower battery capacity than expected. We've isolated this to a limited number of customers experiencing this issue. Based on our investigations we can confirm that it is not an issue with the battery cells, and we believe this is something that can be addressed via software. We're working through the details of how we deliver that.

Microsoft did release some new firmware drivers for the Surface Pro 3 last week, but they addressed some other smaller issues with battery life and not the one that is currently being reported.
