What laptop are you considering buying? You can get enterprise-grade laptops that have very high capacity batteries with high performance hardware, or ultra low power laptops that won't drain a battery very fast.I have i5 8400 and Chrome uses 20% of my cpu, sometimes total cpu usage spikes to 50%, I want to buy a long battery life laptop but scared of cpu making my multiple tabs chrome slow or freeze my laptop, like I had with cheap laptop before.
