Why does the iPhone sometimes dim the screen brightness so much?
While playing on the iPhone, I periodically notice that the smartphone reduces the brightness of the display and stops adjusting it. The first time I was very scared. Over time, everything returns to normal. What’s the matter?
A drop in the brightness of the iPhone without the possibility of increasing it most often occurs due to its overheating. Normal screen operation will be restored as soon as the temperature of the gadget drops to a safe limit.
iPhone gets hot due to the following reasons
? initial setup of the smartphone or restoration from a backup;
? being in direct sunlight;
? smartphone charging;
? work with heavy games or labor-intensive processes;
? continuous work with GPS.
Current iPhone models rarely overheat for one of these reasons. Most often, a serious increase in the temperature of the gadget happens when several circumstances coincide.
For example, while launching games and connecting a smartphone to a charger, when charging an iPhone in a tight case with a powerful power supply, while the navigator is operating in direct sunlight.
The operating temperature range for the iPhone is limited from 0 to +35°C, if the internal temperature of the gadget goes beyond the maximum limit, the protective mechanism is activated.
In this case, there may be such problems with the iPhone:
? the brightness of the display is reduced without the possibility of adjustment;
? the performance of the smartphone drops and it can slow down;
? charging is slower, and wireless charging may turn off altogether;
? smartphone flash may not work;
