However, some models are more efficient than others. In this selection concocted by Back Market, you will find the ten best smartphones with the most endurance in terms of autonomy in 2021. But before that, let’s take a closer look at some crucial points concerning the famous smartphone battery and how to optimize its use.

The battery and autonomy of a smartphone

following the use that we do, the autonomy of our smartphone, and in particular that of its battery, can be totally different. Today, it is this autonomy that should allow you to determine before purchasing whether the device will be able to hold up enough to allow you to make calls, regularly check your e-mails, go on the internet, play, use applications, listen. music, watching movies or videos, etc. If you are addicted to your phone, this criterion is essential if you do not want to have to recharge it several times during the day. In addition, the battery is today the main element for 41% of French people when it comes to choosing a new smartphone.

The capacity of a smartphone battery is expressed in mAh (from the English “milliampere hour”, which means milliampere-hour) and indicates the amount of energy that it can store. The higher this quantity, the better the autonomy of the smartphone.

Today, if the capacity of a battery is on average around 3000 mAh, we are starting to talk about a more powerful battery from 4000 mAh. However, we should not only rely on this single criterion since the quality of a battery can totally differ depending on the smartphone, its equipment, its software optimization and the use of the latter. If you use your device all day, even with the best battery life, you won’t be able to expect miracles.

How does a smartphone battery discharge?

Firstly, if you go for a smartphone with a big screen, it will inevitably consume more than a smaller one and if you use it regularly, its processor will also require more power.

Then, the autonomy of your device will necessarily depend on what you do with it. The battery will not discharge at the same rate depending on your activities. For example, a thirty-minute game on a 3D game will be much more energy consuming that the same duration on social networks which nevertheless already consume a lot of battery. Some streaming applications like Netflix or YouTube are also very energy intensive given the fact that they generally require viewing on the entire screen.

How to extend the autonomy of your smartphone?

If you want to save as much battery as possible, you can adopt simple actions like close all applications open that you are not using in the background, switch to the dark mode (available on most smartphones), disable certain features such as vibrator or the push notifications applications, reduce the screen resolution or, if this is possible according to your use, activate the energy saving mode.

Note that if you use applications aimed at monitoring and optimizing your battery, paradoxically, these may affect the autonomy of your smartphone since they run in the background to close other apps.

What is the lifespan of a smartphone battery?

We know only too well that certain technologies quickly become obsolete, we often speak of planned obsolescence. A smartphone battery is no exception to this observation. On average, a phone battery can withstand up to 1000 cycles, which corresponds to an average lifespan of 3 to 5 years. However, you will have noticed that replacing a broken battery on a smartphone is not as easy as before since the latter are less and less removable. It is also this factor (among others) that influences the lifespan of a mobile phone since it is currently estimated at only 2 ½ years on average.
