A wireless connection uses less battery power than cellular data, Apple says. It is also an opportunity to make a gesture for the planet because Wi-Fi consumes 23 times less energy than 4G, according to a study published in 2012 by the University of Michigan (United States) and from the American mobile operator AT&T.
While it won’t save much power, turning off its Location Services may help, Apple suggests. Likewise for Bluetooth, WiFi or mobile data if they are not used. In general, switching to “airplane mode,” i.e. cutting off all connections, saves an additional 30 minutes to watch a downloaded video on an iPhone, according to tests conducted by Mac World magazine. These tools consume few resources but it’s always taken!
When the storage capacity of the phone exceeds 80%, the device is forced to work harder to perform its tasks. The solution ? Sort through your applications and eliminate those you don’t use. Doing a little tour in the photos and videos in order to transfer them to a cloud or a hard drive is not too much either! It is also recommended to limit the number of notifications received via these applications, keeping only those that you consider useful and disabling the others in the settings.
It is also possible, to save battery, to disable the refreshing of applications in the background, points out Apple. An app goes into the background when not in use or closed. On the other hand, it would be counterproductive to insist on closing all the applications once launched: a “dormant” application is ready to use, while the one that has been closed will have to completely reload and will draw power. energy.
Putting your phone on maximum brightness can be very energy-consuming. It is therefore better to reduce it if our environment allows it, in other words if there is not too much sun. Auto-brightness is an option that allows the phone to adjust the brightness level on its own depending on the lighting conditions.
It is also possible to switch your phone to “dark mode”, that is to say switch the background color of the system to black. This will allow the device to illuminate fewer pixels and therefore consume less power.
In the same way, replacing your beautiful wallpaper with a black screen or making sure that your screen stays on for as short a time as possible by reducing the time before going to sleep in the settings are other solutions.
It is advisable to apply the “40-80” rule, i.e. keep the battery charged between 40% and 80% at all times. You should therefore not wait for the phone to be completely flat to recharge it, nor charge it to 100%! Unlike old nickel batteries, lithium batteries better support short cycles, with several regular recharges.
Similarly, when you store your phone in the closet for a long time, it is better to store it with a 50% charged battery and then turn off the device, explains Apple.
“If you charge your laptop to 100% and keep it at 100%, leaving it to charge overnight, this will have a negative effect on its aging”, because of lithium-ion batteries, summarizes Dominik Schulte, general manager of the German battery technology consulting company BatterieIngenieure, quoted by the American media Business Insider. Modern chargers are supposed to automatically cut off the power as soon as the battery reaches 100%. Except that in reality, the phone discharges even when it is not used. The charger then continues to power the phone as soon as it detects the slightest discharge. This alternation between mini-charges and mini-cuts risks altering the autonomy of the battery in the long term.
