IPhone Battery Common Questions and Answers


Without installing third-party applications, the battery life of the iPhone in normal use is designed for about a day. However, often, instead of checking e-mail and reading online newspapers, many of us spend time in applications such as Instagram, Vkontakte, Facebook and Yandex.Navigator, etc., which use screen backlighting, transmit data and require permanent GPS connection.

Installing iOS Updates Reducing iPhone Battery Life?

I don't receive iOS updates, what should I do?

It’s true! But temporarily.

Whether you’ve bought a new phone or are upgrading an existing one, setting it up takes a lot of power. This is because the receivers turn on and stay on while they reload all your programs, games, photos and videos, processor and storage systems as the device refreshes indexes and libraries.

If you’ve just restored or updated your device, connect your phone to a stable Wi-Fi connection and leave it on for a while. Background automatic system configuration after an upgrade can take from a few minutes to several hours.

Do I always need to force close (unload) all applications?

Multitasking on iPhone X

In truth, almost all the time, iOS is better at managing apps and resources than humans could. The OS will support what it can, shut down everything else and keep everything it can. We discussed in detail why applications do not need to be unloaded in this article.

However, from time to time, applications start to consume too many resources. Sometimes this is a direct increased consumption of resources, and sometimes it is a simple software error.

If you see unusual battery consumption, you can try to find out which applications caused this by going to the battery consumption monitoring screen, for this:

Open the Settings app and go to the section “Battery”. Click the tab “Last 10 days”for a more detailed overview of power consumption.

Active apps on iPhone

Sometimes it can be due to iCloud activity or downloading large files. If so, everything should return to normal when the download is complete. If any application consumes 40% in background activity, this may be a reason to intervene – to force the application to close. For this:

On iPhone with Face ID

Touch your finger to the gesture area at the bottom of the screen;

Swipe up and hold your finger in place until the multitasking interface appears;

To unload (close) the application, simply swipe up on the thumbnail.

On iPhone with Touch ID:

Press the Home button twice to open the multitasking menu;

Navigate to the application you want to force close;

Tap an app and swipe up from the screen.

Fast charging or wireless charging killing iPhone battery?

Partly true. Lithium-ion batteries do not handle high temperatures well. They can recover from exposure to cold, but heat kills them.

In hot weather, do not expose iPhone to direct sunlight. If it’s winter, try not to leave your iPhone on or in front of a heater, even in a car.

However, the faster you charge the device, the more heat is generated in the process. At the same time, iOS does a lot of work to manage charging, including managing fast charging. You can only face the consequences of such battery use in the long term, after a few years. In other words, if you change your iPhone every 2-3 years, don’t even bother yourself with this issue.

Should I always keep my iPhone turned on and never let it fully charge?

As in the previous point, you can make a small difference in battery longevity by carefully controlling how often and how much charge your phone uses. However, this significantly affects the usability of the device.

How to check the battery status

1. Launch the Settings app;

Can I leave my iPhone on charge overnight?

Continuous “overnight charging” will gradually shorten the battery life.

When you leave your smartphone connected to the charger overnight, the battery is discharged from 100% to 95-98% and then recharged again. This cycle will repeat itself several times during the night. As a result, a large number of charge cycles will be wasted without even actively using the phone (in detail).

However, with the release of iOS 13, Apple has implemented a new algorithm called Optimized charging battery that can keep the battery at about 80% overnight, sometimes shutting it off completely. And already about an hour before the user’s usual rise, iOS will restart charging, so that by the beginning of the day, a smartphone with a 100% full battery is in hand.
