Yup, totally agree. Changed my microwaving habits a few years back. 3 minutes at about 600 watts works like a charm for just about everything. Add a minute or so if you're heating soup or something else with a lot of mass/water.
I always did 2 minutes at maximum power previously and it was always like the surface of the sun on the outside and cold on the inside.
I think 4G was a lot of speed for mobile devices but I must say the speeds on 5G are quite impressive. I can get about 50-70mbit/s with 4G on my phone while 5G does 300+. Do I ever need that? No.
I think it would have been better to invest in better coverage with 4G.
