When I turned it back on this time, it was at 72% after being shut down and unplugged for a day and a half, and it took over an hour to charge to 100%. So the "72%" number was accurate. Therefore, the "fix" I performed earlier in this thread was not an actual fix for this issue.So it seems to me that this is a case of battery level sensing, not actual battery level.
How long does it take to charge back to report “100%”?
Which update did you install? The latest firmware I can see on the MS Site is still Sept 6th? Will be very happy if this is resolved!My SP6 is core i7/8/256. When battery full charged, I unplugged ac and shutdown after a while then restart the battery was drained 25%. But it was fixed after update new batch on 26 Sept.
Agree... a patch should be able to fix. The reason I am about 99% positive it is a software related issue is because I have tested where I will unplug at 100%, walk down to my basement with my laptop and open it back up and it is at those levels. This is happening in about 5-10 min max. I haven't seen a program yet that could chew through a battery at that level. Plus the only thing I have running is MS products (outlook and teams) in most all cases. Very odd indeed... but again the sleep setting is a for sure workaround that has helped. I just don't hibernate or shut down at all any more.It is strange that 75% or 73% are commonly quoted here. It is as if either there is true battery use down to that level (75%), then the software truly shuts down, or that there is an error in sensing after restart, and it takes the recharge logic and circuitry the normal time back to 75% through extra slow recharge.
Strange. What firmware or software has messed up, subsequent firmware or software should be able to remedy.
