Andreas Osthoff | April 2023
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."

"The Lenovo IdeaPad 3 17" defies expectations. Indeed, it is just a minor upgrade over last year. However, this doesn’t make the laptop any less terrific. It’s got a great performance, courtesy of the Ryzen 5x25U processors. In addition, you get a pretty good battery life. Perhaps, the 2-hour decrease in video playback, compared to last year is not great, but still, 10 hours of Web browsing and 7 hours of video playback is okay for 17-inch notebooks."
