My SP4 gets very hot and drains the battery very fast even though it is asleep. I found it very hot in its sleeve and down to 28% earlier today. Found it dead later in the afternoon. This is one of MANY issues this device has.
(My SP4 is not part of the insider program)
I had similar issues with my surface pro 4 I-5 unit, including battery drain while asleep and even battery drain while doing ordinary surfing and none power hungry functions. Also the fan was also running a bit "too much" for my tastes and the device was
getting hot under normal operations.
I conducted battery drain tests on it while watching a 1:47 minute DVD movie with 50 percent brightness and the device only had 11 per cent left after the movie. This was not acceptable so I contacted Microsoft support and this is what happened:
The tech listened to my complaints and had me hold the power button for 60 seconds without releasing it. After this he had me power the unit up again and check for any new windows updates, which there was not any. Then he had me make a note of the battery
percentage and instructed me to play a video for a few minutes (while he waited I must admit). I did not tell him but I turned the brightness up to 75 percent while watching the video. After watching the video for about 3 minutes he had me check the percentage
and amazingly the numbers had not changed!
I did not get too excited but told him that battery indicators often take jumps a few percentages during power drain so he had me watch the video again to check my theory. (I forgot to mention that during all of this time the fan never came on-not once
and the unit did not get warm) After watching the video again for about 2 minutes the power meter only dropped by about 1 per cent. My device has been operating fantastic since this phone encounter. No heat; and honestly I have not heard the fan one single
time in the last 4 days of use! I checked the battery percentage of the device a couple of times before it went to sleep and went back to it a couple hours later and the percentage was "still the same". Most important is my battery performance is much better
and lasts much longer. Its hard to put a number on how long it will last on a charge but I can tell you this, I now use the device without constantly watching the battery indicator and I now am enjoying it much more, for this is truly a very good model.
The tech explained to me that sometimes when the unit comes from the factory the drivers are not properly seated or (some other word he used) and that when I held the power button down it forced them to reset themselves. This really was the trick for me,
and I hope this works for others. This is also proof that the Surface Pro 4 units might just have minor bug issues that can easily be corrected by working with Microsoft. Hope this helps someone like it did for me.
