I bought my Dell XPS 13 9343 in January 2015. Now is May 2020 and it is still working so well others couldn't even tell this machine is over 5 years old! It has been with me through 4 years of university (I'm a business analytics and accounting major). At this rate, I don't think my laptop is going to die or even slow down anytime soon.
Granted I take extremely good care of it. I only dropped it once from a table to the floor. The side of the screen was mopped a little, but everything else was fine.
And battery life is a beast too! I have never replaced my battery and a full charge still lasts me 4-5 hours of light browsing and 3 hours of heavy work. The trick is to always charge the battery between 40-80% (I usually do 50-75% though), and you'd be guaranteed that your laptop won't run out of juice till you can get to the charger.
I bought it for $1200 USD 5 years ago, which was pretty expensive back then for 8gb ram, core i5 and 256gb. You get what you pay for and I am so glad I bought this laptop. Dell wins my trust forever!
