I always view such claims with a very big grain of salt.

CPU's aren't the big power hogs any more (Unless you are gaming) And what I find what typically happens is they increase the screen size/brightness/resolution, or decrease the battery size (mAh) to save cost. I haven't seen runtime budge much in recent years due to these factors.

My Asus EEE 900 had about 6-7 hours of battery life.

It had an 8.9" 1024x600 screen with a 900 Megahertz Celeron, a 16 gigabyte flash SSD and 2 gigabytes of ram.

Back in 2008 these were still terrible specs but that's the price you had to pay for a laptop/netbook that could fit in your pocket "assuming you had cargo pants" and had 6+ hours of battery life

The Celeron used was a 5 watt CPU which as you can imagine slowly sipped mAh from the battery.

I see no reason why AMD couldn't move the POWER---------EFFICIENCY slider all the way to efficiency and release a few extremely low power CPUs .

The Ryzen 7 4800U 8C/16T and the Ryzen 3 4300U 4C/4T share a 10 watt minimum configurable TDP.

I can only assume the reason their TDP is equivalent is due to the base clock on the Ryzen 3 4300U being 2.7 gigahertz and the Ryzen 7 4800U being 1.8 gigahertz.

I'm sure a 5 watt Ryzen 3 4300U Ultralow Voltage at 1.8 gigahertz has a market, especially if it allows marketing to say 24 hours of battery life.

If anything I just miss pocket sized netbooks that just so happen to have crazy good battery life.

States that only 1 will reach that 18hrs - depends on the specs. probably one with a dim screen and very large battery pack.

I have an Ice Lake i7-1065G7 Dell 13 2-in-1 (1920x1200, 16GB,1TB) and I get 12 -13 hours of use - the previous gen Dell 13 I had before would get me about 9 hours. This is not a DTR and for my use case, the 12 hours is more than enough - never that far away from an AC plug. The new Dell is much speedier than the old Dell - noticeably faster.

IF Dell releases a Ryzen 4000 based 13/15 and can compare against a Dell 13/15 with Cascade Lake and Ice Lake - then we can see how they stack up
