I have a Dell G3 3579 with intel i7 8750H and the same problem is occurring to me. Whenever I unplug the power plug, it instantly limits the cpu power to 15W. Very annoying problem, I hope it to be fixed soon.
I only have a few days in my return window and I'm packing this thing up tonight in anticipation of no resultion here. This is NOT a laptop it's a portable desktop that always needs to be plugged in. What a joke. Without resultion you can bet your bank I'll be spending my free time making sure nobody else in the gaming community makes the mistake we did here.
This CPU throttling on battery power is appearing in the last 6 months on Dell Latitude E55xx and E74xx business laptops also. Prior to 6 months ago, the issue didn't occur for the few dozen laptop machines here.
The 2.3 Ghz i5 CPU drops to 0.39 Ghz within a second of the dell supplied power cable being disconnected, and switching to run on battery power.
Same occurs under a new windows 10 install (1803, 1809) or under Ubuntu Linux, latest bios firmmware and dell support updates, and intel power management.
There is only the internal Intel graphics card, so it's not likely to be tied to overheating sensors.
This needs a fix or workaround or we'll have to drop Dell as a supplier of laptops. We didn't want to buy bad performance desktops with a UPS.
We require the machines to be usable while away from the mains plug..
Having the same problem... G7, the CPU is always around 800 Megahertz and 1.2 Gigahertz. making it useless when unplugged. Really hoping for a fix quickly, I use engineering software which needs a lot of resources... which is why i bought this laptop, but i find it super annoying having to pull out the giant charging brick every time i need to move an object on a 3D print file.. its either that, or waiting 20 minutes for it to slice... when its done on 10 seconds with the power brick.
Dell Support stated that they are still looking for a proper BIOS for the G5 and G7 laptops with this thermal throttling problem even after the 1/22/19 BIOS update version 1.8.0.

could you use a program like intel xtu/throttlestop to see the power usage on battery? I imagine still limited to 15 watts.

Its still limited to 15W, just not throttling down to .8 ghz anymore, mostly stays around 2 ghz or so.

Nevermind, it was throttling less because of the undervolting. The problem still persists.

After running support assist earlier, it really seems a lot better.
Thanks dell engineers!

I had the very same issue and just recently updated to BIOS version 1.8.0.
It has fixed the problem entirely.
