71-90K Non-gaming laptop for work

My friend bought this Lenovo laptop offline 3 days ago
I bought the 14" variant of the same laptop from Lenovo website for my cousin who is a designer, customized it with 32GB RAM & 3 year ADP, cost about 73k after card offers (or 68k is SBI cashback got double cashback, yet to check statement).
 
how's the battery life holding up during day to day tasks?
His usecase is only work stuff, documents and PowerPoint. He says battery holds up his entire work day and plugs in the battery the next day after arriving for work. It is vague information but I would say around 11 hrs of office use
 
Dell is overpriced & their build quality nowadays is also not as good not to mention they charge around 7k for 2 years extended warranty incl ADP which is a must have for any brand laptop nowadays unless you only want to rely on your luck after 1 year of purchasing the laptop. Also, you won't get rj45 port in most non-gaming/light weight laptops nowadays.
do you mean now days laptop hardware so weak that it didn't last after 12 months ?
