Maybe That’s Why It Runs At 400MHz?
Microsoft’s Surface Pro tablet/laptop hybrid devices have been in the news lately; but not in a good way. Last week we heard tell of a firmware update that might have been the cause for numerous users to report their devices preferring to run at 400MHz and they are still awaiting a permanent solution to this return to hardware of days past. Today it is battery life, though one assumes you are unlikely to suffer from both at once.
The Inquirer has heard tell of numerous Surface Pro (5) and 6 devices which can hold a charge for hours … a whole two of them! From the age of the hybrids battery degradation does not seem the most likely cause but cannot be ruled out. Hopefully it is something in a recent software update which can be reversed.
While battery degradation would seem like the culprit here, there's a good chance that something on the software side in Windows 10, perhaps introduced with a recent minor update, is potentially behind the unexpected battery draining. Microsoft has yet to shed any light on the issue.
