Dell XPS Plus 9320 Battery Problem & Overheating & Not Sleeping

Processor: 12th Gen Intel(R) Core(TM) i7-1260P 2.10 GHz

RAM: 16.0 GB (15.6 GB usable)

SSD: 1TB

Screen: 3456x2160 OLED

I bought the XPS 13 Plus 9320 with very high hopes. Everything was going very well until I noticed the battery life.

Even when low brightness, power saving mode is on and just browsing the internet, it performs 3-5 hours.

Other than that, it gets extremely hot. It's almost impossible to use the keyboard without sweaty hands!

Other than that, I closed the XPS lid and left it in sleep mode overnight (or I thought it did!) and when I woke up in the morning it was fully operational with its fans, incredibly hot.

It's really sad to see such mistakes made by an over-known brand like Dell. I really want to use the XPS, but with this battery life and this much heat, it is definitely not suitable for daily use.

If I can't find a solution to these problems, unfortunately I will have to return it.
