Batteries wear out faster above 80% capacity. It is therefore recommended to avoid charging them overnight: “They would spend too much time at 100% and this would damage them prematurely”, explains Olivier Simon. Especially since some brands are not very cautious: “While testing the charging of mobiles from different brands, we found that several models…
Avoid full discharges
There is no need to discharge a lithium-ion battery to 0% from time to time, contrary to the practice that prevailed with certain older generation batteries. It is even now not recommended: this type of battery degrades more quickly when it drops below 20% charge, a “danger zone” to be avoided as much as possible….
How to take care of your smartphone battery
Avoid high temperatures Modern smartphones are equipped with lithium-ion batteries, designed to be used between approximately 10°C and 30°C. When they are exposed to higher temperatures for a long time, they degrade more quickly. It is better to avoid placing a smartphone in direct sunlight, especially when it is charging. The worst overheating scenario combines…
Some tips to maintain your smartphone battery
As we have seen, iOS and Android optimize the use and recharging of the battery as well as possible. The fact remains that it is possible to increase its lifespan by respecting a few basic rules. Preferably recharge the battery when it indicates between 20 and 80%. Do not wait for it to drop below…
Which is more efficient, iOS or Android?
In this race for autonomy, who is the best? “On consumption in use, Apple and its iPhones are ahead with six devices in our Top 10”, points out Olivier Simon. Apple masters both the hardware design and the operating system, so it’s easier for this computer giant to optimize battery usage. “With a smaller battery,…
Optimization of operating systems
However, the iOS and Android operating systems manage search and battery usage better and better. A few years ago, Sony took into account the morning alarm to adapt the recharge to 100% a few minutes before. A strategy widely adopted by other manufacturers. Google has greatly improved its operating system, especially since version 9 Pie….
The 80-20 rule for charging
On how to recharge your batteries, the results are more in line with our expectations. Thus, you are 60% to recharge your mobile as soon as the battery is less than 20%, which is a good reflex to limit wear. Indeed, as Olivier Simon explains, batteries degrade more quickly when the voltage is very high…
Smartphone battery: good habits to adopt for more durability
Everything for autonomy! According to our survey, you are a huge majority — 92%! — to prefer good battery life to fast charging of your smartphone. A more than clear-cut opinion which, let’s face it, surprises us a little. Indeed, a few years ago, batteries had a ridiculous autonomy and fast charging was just wishful…
The good gestures
No matter what your charge indicator says, your device will never actually be 100% charged or completely discharged. It is the software integrated into the phone that manages these problems. The most useful advice to preserve your battery is therefore to charge your phone on long fixed beaches in order to avoid small deleterious recharges….
Charging, myths and reality
To understand how to optimize the life of your battery, you have to have in mind, very schematically, how a lithium-ion battery works. During charging, the anode (the + pole) will receive and accumulate electrons from the lithium placed at the cathode (the – pole). The current from the recharge somehow “rips” the energy present…
