Is a discrete graphics card important to a mobile developer?

Question

Iron

I develop in C# and Xamarin.Forms, I run all the tests on the emulator, since there is no phone on the android. There was a need for a laptop, as lately I often travel long distances. Maximum budget 50000.
I can't choose between Honor MagicBook KPL-W00 and Lenovo IdeaPad 330S-15IKB (81F5016YRU)
Lenovo Pros:
Larger screen (15.6 vs 14)
Availability of a discrete graphics card and RAM expansion
for 10 thousand cheaper
Honor Pros: More
compact and autonomous
Much more more powerful processor (Ryzen 5 2500U vs i3-8130U)
Considering all this, I can’t decide which is better to buy: on the one hand, compactness, autonomy and reliability, and on the other, a more powerful and cheaper device.

Answer 1

If you don't like to play in between work, you don't need a discrete graphics card.
Ryzen has its own built-in quite a good video card.
On the other hand - other things being equal - Ryzen eats more power even when you're not gaming. Again, because of the video.
Discrete video is turned off as unnecessary and autonomy is higher.
But it is necessary to see specific models, because it can be vice versa.
I would add to the comparison on Intel, but without a discrete graphics card. Hypothetically, ceteris paribus, these models should be the most productive and the most economical, if you do not play and do not do 3D graphics.
PS:
If autonomy is critical, I would consider a laptop with a replaceable battery + a spare battery (if you really need it, then 2 spare batteries).

1. Autonomy will be much greater then.
   
2. Batteries can be bought a little later, when the money will be.
   

Answer 2

Energy efficiency IMHO just do not be considered as a selection criterion.
If there is not a single outlet around, then you should think not about programs, but about how to leave this damned place and return to the mainland.
Any issue with free sockets is solved by a threesome in a bag with beech, you can always climb somewhere with your threesome.
It is worth reading reviews and reviews, because. Intel, for example, is famous for the fact that it likes to troll for any reason.
It will be of little use if it works at 2.8 GHz most of the time.
