Any iPhone we have, be it an iPhone 5S, a 6, 6S, or 7, Plus or even the newer iPhone, the battery life may be shorter or longer depending on how certain options are set.
Referring to the most recent version today, iOS 11, let’s see what those are options to configure to save battery on iPhone for increase the durability as much as possible, without obviously sacrificing the main functions of the smartphone.1) Check which apps download the battery
First of all, you can open the energy saving options in Settings -> Battery to check which apps used the most energy and downloaded the battery first.
Once the most used apps are discovered, we can remove them or make sure that their use is optimized as we will see in the next few points.
2) Check location services
The use made by the installed apps of iPhone location services is among the first responsible for battery life issues.
Except for a few exceptions, it is important to make sure that no app uses location services if it is not in use.
Then go in Settings> Privacy> Location to view exactly which applications are set to access the device location.
For each app, tap and set the option “if in use” or even Never.
The only app that can be configured to use localization “Always“, is that of the Weather.
3) Set the low brightness
Unless you have special requirements and if you are not always under the sun, the brightness of the iPhone must be configured as low as possible, to avoid unnecessary battery consumption.
The brightness on the iPhone can be changed quickly from the Control Center.
In this regard it is worth deactivating the automatic brightness by going into Settings> General> Accessibility> Screen Adjustments> Automatic brightness.
Going into Settings> Display and brightness, activate automatic night brightness (Night Shift), which in addition to saving energy is also less tiring for the eyes.
4) Deactivate features if we do not use them
If we do not use one of these iPhone features, we can disable them to save some battery power:
– handoff is Airdrop, two connection and resource sharing functions can be disabled in Settings> General.
– iMessage, Facetime, Game Center to be deactivated in Settings.
– Apple Music, to be deactivated in Settings> Music.
– Raise to activate, the function that turns on the screen when you pick up the iPhone, to turn off in iPhone 6 and iPhone 7 by going into Settings> Display and brightness.
– Physical activity monitoring, to be deactivated in Settings> Privacy> Movement and fitness.
– Hey Siri, to be deactivated in Settings> Siri
– ICloud keychain, to be deactivated in Settings> Accounts> iCloud
5) Energy-saving mode at your fingertips.
On iPhone, in Settings -> Battery, you can activate the energy saving mode, designed to limit unnecessary system services and save battery.
With this mode, for example, emails may not arrive in real time.
One of the best tricks of iOS 11 on the iPhone is to quickly activate battery saving from the Control Center appearing by swiping your finger on the screen from bottom to top.
Then go to Settings> Control Center> Customize Controls to add the button that turns power saving on and off.
6) Turn off apps in the background
The iPhone battery is directly influenced by all the apps that send notifications and remain constantly active and ready to receive data.
Then go in Settings> General> Update app in the background is disabled all applications present except that of Emails (if you use Gmail or others), except for Google Photos if you make automatic backups, except for message apps like Whatsapp and then Weather.
All the others, including Facebook or other social networks, should be kept off.
7) Do a Hard Reset
The hard reset is the procedure of rebooting the iPhone that solves every problem, to use every now and then if the apps seem slow and if the battery gets too fast even if nothing is done.
The procedure is not a real reset and does not delete apps and personal data, it is more a forced restart that resets some internal iOS system parameters.
To do a hard reset, press and hold the keys together Turn off the screen is Home.
8) Calibrate the battery
To calibrate the battery, wait until the charge runs out completely, then put the iPhone off in charge up to 100%, leave it a couple of hours longer, unplug it and then turn the iPhone back on in hard reset mode, holding it together Home button and power button showing the Apple logo on the screen.
I would say not to go further with the options changes, considering also that some problems lead to discharge the battery (or see a wrong percentage) of the iPhone they can be caused by system bugs that we cannot surely resolve on our own.
