I used to have up to 8-9 hours battery life with Microsoft 3. But since installing Windows 10 I am down to only 3 hours and 18 minutes. Why is this so and is there any tweaking I can do in the Surface Pro to extend battery life?
This appears to be a common problem for a lot of users and there are several battery threads for all x86 Surface models that have upgraded to Windows 10. Many have been resolved over time. Take a look around at the various existing threads.
I just recently seen my surface 3 battery time drop below 4 hour seven when plugged in
I have removed all start up applications
i'm running at 25% brightness and not getting four hours
ab out 12 hours to charge
