PerfectRec’s screen quality scores take into account various important factors that are relevant for different use cases.
Battery
9.0 Hours
7.0 Hours
The ASUS TUF Dash 15 has 9 hours of battery life. The Lenovo Legion Slim 7 has 7 hours of battery life.
Battery life estimate is based on a mix of common use patterns. More portable and higher performing laptops tend to have less battery life.
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
