It's been over a week since Surface Pro 3 users began complaining about battery issues. Microsoft quickly confirmed the issue, saying that a fix is a "top priority for our team".
A few days later, the device received a bundle of firmware updates, which didn't fix the problem. The battery issue is only present in Surface Pro 3 models with SIMPLO batteries, so many feared that it was a hardware issue.
Luckily, Microsoft has confirmed that this is not the case. The firm believes that it's a software issue, and it's working on a fix. In a forum post, Greg from Microsoft's Surface support team said the following:
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.
Thank you all for the details you've shared here,
It's clear that not all Surface Pro 3s are having battery troubles, but if you are, you can rest easy knowing that there's a fix coming soon.
