I have a 15” FHD dell xps 15 9560. I upgraded the ssd to samsung 970 512gb 8gb ram to 16gb & Repasted the pros & vga. After doing so my battery life seems to be down to about 2/3 or 1/2 of what i had. Battery condition is 100% Do you think i did pasting wrong? Any suggestions?
If you mean you cleaned the thermal grease off of the processor and gpu then if it was not done right it would lead to overheat conditions. You should run the Dell diagnostics, restart computer and press F12 to bring up the menu and select diagnostics. The SSD you installed may be the cause of the power change, diagnostics should help with that.
