Batgtery life, temperature, noise level
A while back we tested AMD Ryzen 7 4800H in Asus TUF A15, and it peaked at 97.5 oC in our tests, while Legion 5 goes up to 99 oC. However, the cooling system used by Lenovo is a bit quieter, with the meter recording 41.3 dB, compared to the 44.5 dB reached by the Asus model, so this difference could easily be turned in Lenovo’s favor with a more aggresive fan profile. However, it is possible that this is only a characteristic of the sample we used for testing, and retail versions actually do have a more aggressive fan profile.
In terms of battery life, Lenovo Legion 5 15ARH05 has good performance, providing over 9 hours of work, 4 hours of intensive work or 3 hours of gaming away from the socket. It is not an ultra-portable and we cannot expect the same numbers, but overall you can work for a quite a while away from the power outlet.
