Adam Kos If you don't live in the mountains, this year's winter season is already starting to grow, but we haven't seen drastic minus temperatures yet. And it's definitely good for your iPhone, especially if you own one that's already a year old. Older iPhones, in particular, suffer from frost in such a way that they simply turn off. But why is that so?
iPhones use lithium-ion batteries, the advantage of which is mainly faster charging, but also longer endurance and higher energy density. In practice, this means nothing more than longer life in a lighter package. If you are asking if there is a downside, of course there is. And as you can guess, it concerns the temperatures. The battery is quite susceptible to their range.
The operating temperature of the iPhone is from 0 to 35 degrees Celsius. However, a plus point for the winter season is that low temperatures do not permanently damage the battery, while warm temperatures do. In any case, the frost has such an effect on the iPhone that it begins to develop internal resistance, due to which the battery capacity begins to decrease. But her meter also has its share in this, which begins to show deviations in accuracy. It simply means that even when your iPhone is charged at as low as 30%, it will turn off.
Low power mode will also help with endurance
Check the battery condition
There are two problematic factors here. One is the reduction of battery capacity due to frost, in direct proportion to the time it is exposed to it, and the other is inaccurate measurement of its charge. The above value of 30% is not accidental. The meter can show just such a deviation from reality in extreme temperatures. However, with new iPhones and their battery that still has around 90% health, this rarely happens. The biggest problems are older devices whose batteries are no longer fully powerful. In addition, if it is at 80%, you should consider replacing it. You can find this by going to Settings -> Battery -> Battery Health.

Simple fix
Even if your iPhone turns off, just try to warm it up and turn it back on. However, you should not do this with hot air, body heat will suffice. This is because you will make the meter come to its senses and it will then know the real capacity without the present deviation. Anyway, even if you don't like it, you should generally only use your electronic devices in the cold when absolutely necessary. Scrolling through Facebook while waiting for public transport in minus 10 degrees is definitely not ideal.
