I just bought a barely used (22 battery cycles) SP 2017 LTE (i5/8/GB/256GB) , got it all updated and it works like a charm - But...terrible battery drain! I mean like, 10% in 20 mins of very, very light usage. I've Googled it up and down and the problem is reported (since June), widespread and no solutions offered by MS or anyone else. The MS comments are restricted to "working on it!" I need to put this into use immediately and it won't serve its purpose with this kind of battery drain (btw, not even using LTE, nor is is hooked up). Can anyone help or shed light? I'm in a bind. Seems to be a 1903 problem and doesn't just affect this model. Thanks!
