Windows 10: Battery charge percentage shows 1% after reboot

Hoping some computer wiz can help me out here, Im at a loss...

My system: Dell Inspiron 7373 2in 1 with 64 bit Windows 10 pro, Intel i7

This laptop has done this since new. This thing is still under warranty but I really dont want to have to transfer all my stuff from it for a new unit.

The issue: If the laptop is powered down, only when a battery charge level of below about 35%, on reboot the battery will show a critical warning and only 1% charge. This reboot can be immediately after shutting down, or hours/days later.

If you ignore the low battery warning, the battery will continue to operate at 1% charge for a couple hours before dying. If you were to plug in the AC charger, for even 1 second, and then unplug it again, the charge will immediately go back to the last "true" reading of 35% or wherever it was last shut down.

The issue will NOT present itself if the laptop is shut down at a higher charge level (above 35% or so).

What has been tried:
-New battery from Dell under warranty.
-Uninstalled all Dell power savers / battery programs
-Deleted battery driver and reinstalled
-Conditioned the battery multiple times by fully discharging and then fully recharging
-Made sure BIOS is up to date
-Disabled windows fast boot
-Deleted all the intel Rapid storage software (From a post suggestion I read)
-Ran windows battery check without finding any issues, as well as a system config check
-Checked battery status in Bios, it matches whatever windows shows
-Ran windows battery report which shows the instant charge change with time stamps, but shows no other issues

Im sure there are a few other things I tried, but Im totally out of ideas and desperate for help. Thank you in advance!

Laptop charging but not increasing battery charged percentage

My HP Probook 4530s (Windows) can charge when it is shut down but cannot increase the battery charged percentage while charging when it is on (although it shows that the charger is plugged in and charging).

Why is this happening and how I can make it show the current battery charged percentage again?

 

battery not charging or 1 minute to full charge


Seems that this issue still happens with the Anniversary Update. Again, it's a trivial issue, particularly as you can click on the battery icon and see the proper percentage, but it's something that shouldn't happen. Actually, mine now says "03 minutes to full charge", and that's despite it only being 11% charged in reality.

Edit: What I've noticed is that if the real percentage of the charging battery reaches something like 70%, then all is displayed properly on the tooltip. I remember something similar happening in my previous post on this thread, in which the battery seemed to "fix" itself when the charge reached into the seventies percent.

 

Windows 10 battery percentage of design or full charge capacity?

Is the battery indicator in Windows 10 a percentage of the design capacity or the current full charge capacity of the battery ?

ie. if my battery capacity dropped from say, 60mWh to 30mWh from wear, would the indicator show 50% or 100% when the battery is fully charged at its current capacity of 30mWh ?

EDIT: to describe my case, I have an XPS 13 9350 whose battery has a design capacity of 56mWh. over the past few weeks, the battery percentage in windows stops at 55 with "plugged in not charging". running

shows that the current full charge capacity is about 41mWh, meaning at 55% I'm getting about 20mWh on a "full" charge. the surprising thing is Dell Command Power Manager shows my battery to be in excellent health.
