The battery life of the Galaxy Tab S9 5G in this review seems to have been compromised by the 5G chip, in the Tab S8 5G, the test was done without any chip, here I notice a good difference in the battery life with the chip active and in airplane mode on the Tab S9.

PWM isn't really the same with OLED screens...  oled screens turn the screen on/off periodically to prevent burning and PWM is usually set at the frequency the screen is turned off/on.  You won't find an OLED without this.

The reviewer does not know it's called the Galaxy Tab and not the Galaxy Pad, lol! He writes Pad 24 times instead of Tab in the review.

what i mentioned in my email towards notebookcheck. NOBODY ever reacts to the comments ...and then they ask examples where thry did not responds? Really , just pick ANY comment!
How can you give this tablet a 91% score with this PWM that bad?
"""However, we detected screen flickering at a frequency of 240 Hz during our tests. From 30 per cent screen brightness, the frequency drops to 120 Hz, corresponding to the refresh rate."""

Its about time this is taken into account into the scores and also mentioned more in the 'CONS' section especially with these low frequency...

Excellent review, interesting to see this Wi-Fi problem on the Tab S9, here with a Redmi AX5400 Gaming, the Tab S9 perfectly connects to the network with a 2400 Mbps link at 5 GHz, unfortunately, in the 2.4 GHz band it is limited to 288 Mbps, as for the charger, here I use a 65W Baseus and another 100W and it charges at a maximum between 35W and 42W, depending on the battery level, battery life is not a strong point, just above average, but fast charging pays off.

And as usual ..... no reply on comment at all....
PWM at 240Hz or even 120Hz used and still a score of 91% ?

Lucky we have notebookcheck who does inform people about this and thus avoiding people spending a lot of money and ending up with headached etc...
Sadly other review sites or Youtube reviewer fail to even mention it....
