Lithium-ion batteries are the most commonly used battery type in today’s mobile devices, including laptops and tablets. These batteries charge quickly, discharge at a constant rate, and have a high energy density that allows for small cell sizes in batteries. By understanding Li-ion batteries a bit, you can optimize the battery life and overall battery…
How does an iPhone battery work?
First of all, I need to explain to you how a smartphone battery works. This way, you will better understand why it allows your phones to last longer. The explanations are a little scientific, but nothing very complicated in reality. The batteries of our smartphones work with so-called Lithium-ion. When the battery is charged, lithium…
Put the battery in power saving mode
This little trick will not be revolutionary but will save your battery a few minutes of life. The “energy saving” mode, which can be activated in the settings, makes it possible to restrict certain functionalities of the phone, such as the use of Bluetooth or GPS when the screen goes to sleep. It can also…
Preserve the battery from the cold
The battery of our phone does not appreciate the low temperatures of winter. It works by a chemical reaction that creates a flow of electrons. The colder it is, the slower this reaction. The cold also leads to an increase in resistance and therefore a decrease in tension. Result: the laptop thinks that the battery…
Prioritize Wi-Fi over mobile data
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.
Turn off location
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…
Sort out your apps
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…
Reduce brightness
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…
Keep the battery charged between 40% and 80%
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,…
Avoid leaving your laptop plugged in all night
“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…
