Which Laptop/Model?

Hello everyone,

I’m currently a college student studying electrical engineering, and am looking for a new laptop as my current one has trouble supporting software such as AutoCAD and is overall just old and janky.

I’m stuck between the Lenovo Slim 7i Aura Edition (14”) with an OLED display, or the Lenovo Yoga Slim 7i Aura Edition (15”).

Based off what I see, the only main difference between these two is the display (slim 7i has OLED, yoga slim 7i has LCD) and the size. The slim 7i is quite a bit cheaper for the same amount of storage, ram, and processor, so I’m leaning towards that, but I’ve heard mixed opinions about OLED screens.

I heavily prioritize battery life, portability, and longevity the most as I hate heavy laptops, and I hope that the battery could last all school day without having to recharge it. I also really like watching videos and movies on my laptop, so I'm not sure which display would be better for that.

If anyone has any experience with any of these two models, please let me know what you think of it! Or, if you have different recommendations around the same price point, that would be great as well.
