MagyarLenovo IdeaPad Flex 5 convertible review: Powerful entry of the small i3-1215U
The Lenovo IdeaPad Flex 5 14IAU7 is a relatively efficient convertible that wants to be a laptop for any occasion in the consumer realm. The performance and equipment are at an elevated level for an office laptop. When you hold it on your lap as a tablet, it stays relatively quiet and cool. At 14 inches, its size isn't absolutely mobile anymore but offers a comfortably large screen area for streaming, surfing, and working instead.
With the Lenovo IdeaPad Flex 5i 14IAU7, we already tested a more powerful version, and now the entry-level version with the smallest configuration and corresponding lowest price of almost 700 Euros (~$737) has to prove itself in this test. The small i3-1215U uses a slimmed down graphics unit with fewer computing units and is only supported by 8 GB of RAM.
A competitor is for example the significantly slimmer Samsung Galaxy Book Pro 360 13, and the Asus Vivobook Flip 14 and Acer Spin 3 SP314 also offer a similar construction and comparable computing performance.

Case and Equipment - A robust IdeaFlex without any gaps
The metal display lid immediately ensures a high-quality and fairly robust impression. The IdeaPad Flex also corroborates this with a relatively high weight of 1.6 kg (~3.5 lb), making it one of the heavier convertibles. The base unit is made of plastic and appears to be assembled accurately. Attempts of warping only lead to limited success, which is probably connected with the high weight.
The display hinges are well adjusted. You can open the lid with one hand up to a 60-degree angle. After that, it becomes harder to open further, in order to prevent some annoying wobbling when the display is touched.
Two USB-A and a Thunderbolt 4 port are surely sufficient for connecting peripherals. With HDMI, an SD card reader, and the audio port for a headset, some additional useful connections are also available. Even though you can charge the convertible via the Thunderbolt port, this is not your only charging option, and the port can usually remain available for other purposes. On the road, you can still charge the laptop with a standard charger or suitable power bank.
The WLAN speed is slightly below average, but at almost 1,000 Mbit/s, the speed is still within the range of a cable connection. The webcam with Full HD resolution delivers a convincing image quality even under bad light conditions. While the corresponding microphone could sound a bit better, it still records your voice clearly and understandably, and reliably even from a further distance.

Input Devices - Convertible with a good keyboard
The keyboard of the Lenovo IdeaPad Flex is close to standard size, which ensures that typing succeeds easily without having to get used to it or needing any adjustment. The stroke of almost 1 mm isn't really impressive, though. However, the resistance of the individual keys can be called well-adjusted. Even longer typing tasks turn out to be comfortable, even if the keyboard isn't able to compete with that of most business laptops. But at least there is a keyboard illumination.
At 12 x 7 cm (~4.7 x 2.8 in), the touchpad has a comfortable size. The smooth surface allows accurate sliding of the fingertips. Only the hidden keys in the bottom area could have turned out a bit crisper.
What remains is the most important input method: the large touchscreen in the 16:10 format allows you to control the IdeaPad effortlessly. The usual commands, even those with several fingers, succeed accurately. Particularly writing using the onscreen keyboard is fun, since the keys are close to the same size as the physical keyboard.
Display - No brilliant colors on Lenovo's touchscreen
Aside from the very fitting resolution slightly above Full HD, the display is not very impressive. The brightness is just barely able to fulfill the minimum requirements at an average of barely 290 cd/m². The contrast value is still okay, even though it tends to be in the lower range at about 1,100:1.
Even though it is rather weak overall, the resolution still makes the display work well for surfing, office tasks, and even video streaming.
We did not notice any flickering of the screen at a low brightness. There is also only minimal screen bleeding, which is not very surprising, considering the fairly weak background illumination.

* ... smaller is better
The colors are not reproduced optimally. At a DeltaE of higher than 6, the deviation in our measurements is clearly within a visible range. But at least there is no noticeable color tint. Photos tend to appear slightly pale and grayish, but if you don't look at them in direct comparison, this becomes less noticeable.
The color space coverage is also at a low level. The sRGB color space used by many midrange laptops is only displayed to 64%. This will become noticeable when looking at highly resolving digital photos. It also makes the display hardly suited for image processing. However, the values are still okay for entertainment purposes.

With the low maximum brightness and reflective surface, there won't be much left to see outdoors. In addition, the maximum brightness is even lower in battery operation. But at least in a shady place, you can still read texts acceptably easily.
Performance - Convertible with an efficient computing core
With the choice among three processors, the Intel Core i3-1215U, i5-1235U, or i7-1255U, the Lenovo IdeaPad Flex 5 14IAU7 offers efficient and frugal computing cores, and a large bandwidth is also covered. The fastest model currently costs 1000 Euros (~$1053).
Our test unit, which is the convertible with the smallest processor, a small SSD, and only a small amount of RAM costs around 700 Euros (~$737). Even with its humble equipment, this is still a good amount more than the absolute entry level segment. However, fast starting of programs, video reproduction that is always smooth, and multimedia should not pose any problems for the hardware. Multitasking, on the other hand, will fairly quickly show the limits of its performance.
Test Conditions
The preinstalled "Lenovo Vantage" software, which unfortunately includes numerous typos and unfortunate translations, offers three performance levels: Extreme Performance, Intelligent Cooling, and Battery Saving mode.
All our tests are run with the Extreme Performance mode, which is also the default mode. However, these settings have no influence on the power limits of the CPU.
Processor
The Intel Core i3-1215U with two Performance and six Efficiency cores in our IdeaPad test unit belongs to the smallest models of the Alder Lake series. However, this also means that it is still clearly ahead of entry-level CPUs such as the Intel Celeron 7300 or Pentium 8500 of the same processor generation.
Among other things, it supports 10 threads, which is reflected in our Cinebench R15 constant load test. For example, it still surpasses the i5-1135G7 of the previous generation by about 10% on average, although that is really a higher-class processor that can be found in many smaller business laptops.
For a mobile i3 processor, the results are impressive for sure. The computing performance should be completely sufficient for almost all nonwork-related tasks. This is also the case when you run two different programs simultaneously.

System Performance
With its limited hardware, the Lenovo IdeaFlex achieves an evaluation that is not very far from the average of all the convertibles we tested. It even manages to significantly surpass a very simple model like the Acer Spin 3 SP314.
The system responds quickly when opening new programs, surfing, or running programs in parallel. On the other hand, installation processes take a bit more time, for example. In addition, too many open programs or numerous browser tabs can fill up the limited amount of working memory completely, which limits the speed massively.

DPC Latencies
The measured latencies are at the same level as those of the competitors. The network drivers prevent better values, but this can be optimized by updates or changed settings.

Storage Solution
Without a larger collection of photos, the offered 256 GB, almost 200 GB of which are available, should be sufficient for all the programs and personal data. Even though the short SSD in the 2242 format is connected via PCIe 4.0, it only achieves the speed of PCIe 3.0. In the constant load test, the transfer rates drop due to the warming of the board, even though it is covered by a thick layer of heat paste.
However, this won't cause a limiting effect. The performance of the IdeaFlex is not sufficient to make full use of the solid access rates. And besides, the competitors are only rarely faster.
