Question about Xiaomi Redmi 9A
Hello Unfortunately, I only noticed after I bought it that the instructions for use state that my device is damaged above 40°. But I'm not sure what exactly is meant by this. Does it mean that I can't use my phone in the summer if it's warmer than 40 degrees, can't enter a room where it's above 40 degrees and mustn't use it for too long because it will overheat and break? Or is this just a warning, meant for when you are exposed to such temperatures for a longer period of time? Thanks for help / answer

Well, of course it's not ideal when a phone gets hot, but the processor doesn't break, but it slows down, that's called thermal throttling. Batteries don't like it hot either. So it's best never to leave a smartphone in the sun. But you have to use it in summer, because you can't buy a phone that you have to hide somewhere all the time.
Another thing is that many Xiaomi phones also have built-in cooling systems, which are called liquid cooling and use copper tubes in which a liquid is converted into gas to cool the processors. Such a system can also help to keep the devices cooler in general.
However, there are much better processors today, because the Redmi 9a has a relatively old CPU with 12 nm layout, modern phones have 6 or even 5 nm technology, which generally do not get very hot and need little energy.
So if the purchase still allows a return, I would return it now, that costs 10% because used, but then I would recommend this phone, it has a CPU that does not get so hot. This would be the case with the new Redmi 10c, for example, because this CPU would have a 6nm structure for the CPU, the smaller this value is, the less heat the CPU generates, i.e. if this number is high, the power consumption of the CPU is also high.
