Despite the fact that my iPhone 13 Pro Max has enough batteries for almost two days of battery life, this is the second summer in a row I make sure to include one healthy dose. It seems that nothing changes when working on a smartphone, but a miracle – it becomes even more “survivable”.
I explain: in hot weather, the iPhone can easily be discharged by lunchtime. may become heated case due to the development of background applications, and as a result, inefficient heat dissipation. It may be that you take your smartphone outside and the brightness is automatically turned up to the maximum, which also hits the battery life.
So every year I turn on a power saving mode that slows down power-hungry iPhone processes, making the battery drain much more economically.
Here’s how to turn on this mixture right now: go to the path Settings – Battery and activate the switch opposite the “Power saving mode” option.
Many people think that activating this mode is unlikely and simply disables some of the visual features of iOS. Even Apple does not talk about all the changes in the operation of the operating system with power saving turned on, limiting itself to a mean phrase about decrease in background activity.
But it is not. Indeed, there are quite a few changes going on that are not noticed that consume a lot of battery power. Below are all of them, take a look and be surprised:
Activate the power saving mode in the iPhone. What changed
The Reddit user got confused and described all the changes. You can see the original here. We offer you a list translated into Russian:
🔘 Automatic screen brightness adjustment works in a sparing mode and will never rise to the maximum, regardless of the surrounding weather.
🔘 Stops the background animation of opening and minimizing apps, and disables wallpaper perspective if it was enabled.
🔘 iPhone automatically goes into standby mode after 30 seconds of inactivity, this value cannot be changed.
🔘 Decreases the refresh rate of data in background applications.
🔘 External video is disabled in Safari browser.
🔘 Unable to access shared album from another iPhone user.
🔘 The screen refresh rate does not exceed 60 frames per second on iPhones like my iPhone 13 Pro Max.
🔘 Two cores are disabled and the clock frequency of the remaining four is reduced from 1.8 to 1.38 GHz.
🔘 Two GPU cores are disabled or the clock speed of all five cores is reduced.
🔘 The smartphone rarely connects to the cellular network and does not jump from LTE to 3G and back.
If you think that performance degradation is somehow slowing down the smartphone, then a quick reassurance: you will not notice the difference. Although synthetic tests reduce performance by almost half:
Power saving mode is disabled.
Power saving mode is on.
Tests were carried out with a battery charge of 75%, cellular modules, Wi-Fi and Bluetooth turned on.
Despite the test results, it is important to consider that these are just numbers. In practice, the smartphone can be used in normal mode, run, rewrite games, etc. without any lags and instabilities in operation.
Turn on power saving mode in summer. Take care of your iPhone
I asked the familiar owners of iPhones what, in their opinion, is turned off in searches when the energy-saving mode is activated. No one was able to list and accurately determine, limiting themselves to guesses about the processor clock speed and some abstract decorations.
So now you know exactly how the magic mode works, which can be easily activated with one toggle switch as a result.
I myself have been using this regime for the second season and I never rule it out. My iPhone 13 Pro Max is perfectly developed with all the apps and games I run including Call of Duty Mobile.
Therefore, I advise you – try it, be pleasantly surprised by the increased autonomy of your mobile device in the hot summer.
