XPS 15 Catalina 10.15.2 issues.

XPS 15 Catalina 10.15.2 issues.

First & main Issue:

Mp XPS has "84 WHr 6-Cell" which should last at least 8 hours ! but for some reason Im having an issue where it lasts only 3.7 hours! when i had Mojave installed it did last 8+ hours but after i installed Catalina and updated all the kexts it drains so fast now.

Second Issue:

After waking from a sleep there is a screen flickering here and there. so i have to turn off the laptop every time i want to close the lid.(Now Im using InsomniaX to disable sleep on idle and sleep on closed lid).

Third Issue:

(This could be related to the network card) so whenever Im connected to the internet using Tp-link AC600 Archer T2U usb adapter, i cannot download anything from App Store. but when i connect the laptop to the Type C Dock-station and use the Ethernet it downloads just fine. ( Planning to buy a compatible network card because i have Intel card now).

4th & (Not quite important) issue:

Siri (Sorry could you say that again). iMessage, Facetime. etc (These worked previously on Mojave).

Thanks in advance for anyone who could help ! :)
