Hi guys. Recently bought the i7-16gb-256gb version Surface pro 4 and spent the last few days setting everything up and testing. What a beast! I think I may have an issue with the power supply though so I wanted to ask other i7 owners if they experience a similar problem to me. When playing a few games with the power supply plugged in, I'm noticing the battery is draining pretty fast (25% ish per hour while gaming, all while still plugged in) It even drains slowly when running something CPU intensive like handbrake when converting videos. But, when idling, it goes back to charging as normal. I installed batterybar to see if I could find any more info and it shows that whilst gaming, it's draining at a rate of about -9000mwh I realise this unit uses hybrid power but, surely not to this extent? Do you guys experience this or is my adapter faulty?
