HOW TO PRESERVE THE BATTERY OF A SMARTPHONE?

Your smartphone represents a small revolution. A small miracle as a pocket computer able to obey almost all your requests. But none of his powers make the weight facing an empty battery. As removable batteries become more and more scarce, your mission is to take the utmost care. Fortunately, with the lithium-ion batteries, this mission is not insurmountable provided you follow a few simple rules.

First, an obvious rule that must be followed is that you do not use all the autonomy of your smartphone by playing Candy Crush or leaving your WiFi or GPS activated when you do not use them. Apart from these essential elements, there are other rules of use and load that can optimize the autonomy of his device.

The Golden Rules

You may remember vaguely a sort of urban legend about rechargeable batteries and their “memory”. You will probably know that if you do not “learn” your battery to reach its maximum capacity by moving it from maximum recharge to zero percent charge, it might forget some of its capabilities. Well, forget all about it. At present, this is not true.

The memory of a battery is a reality but it concerns only batteries based on nickel. But you definitely have a lithium-ion battery that needs to be treated differently. The objective? Recharge it as often as possible.

In order to get the most out of a lithium-ion battery, it is important to maintain a recharge level of around 50%. The yo-yo effect between the lowest level and the maximum load will not help its longevity and may even be damaging in the long term. It is a good idea to perform a complete discharging of your device once a month for the purpose of “updating” but this must be occasional so as not to shorten the life of your battery.

But there is still one but! Keeping a laptop in charge very often also makes the battery heater. Fortunately, the chargers are equipped with a basic form of intelligence and do not send energy to a smartphone whose battery is full. In any case, it is not a question of reaching the ultimate recharge level at each reload, but of stopping the charge just before reaching the 100% in order to avoid that it remains connected for nothing and risk despite All to degrade.

So, to be at the top of the optimization, the goal is to permanently keep a battery level at around 40 to 80% loading. Performing many recharges, even short, will always be less harmful than spending every day from 100 to 0% battery. But these rules are not the only ones to follow.

Keep it cool

If it is easy to adopt good recharging habits, as we did for our previous batteries, you must also be aware that an ultimate enemy can harm your lithium-ion battery: heat. The battery of your smartphone degrades much faster when it is hot, no matter whether it is used or not.

Confronted with an average temperature of 0 ° C, a lithium-ion battery loses on average 6% of its maximum charge in one year. At 25 ° C, over one year, the loss is estimated at 20%, then at 35% when we speak of 40 ° C. Obviously, this does not mean that you should keep your laptop in a fridge, but if you can avoid letting it pass a stay in a car parked in the sun, it is not bad.

Avoid wireless charging

The latest wireless charging systems are a very convenient way to use compatible phones, but this can be a disadvantage. The current wireless chargers have this bad habit of generating a little too much residual heat, capable of damaging your battery. So even if this is a little less practical, be aware that the good old wired recharging technique helps keep your battery in the best possible health at the moment, especially if you live in a warm place.

Never lower to zero level (for appliances left unattended)

The sad reality is that using your battery will degrade it. It will go out slowly, including if you leave a device in a closet without using it. A tip exists however to minimize this inexorable effect of aging concerning the devices little used: always leave a little energy.

Basically, if you do not use a device with a lithium-ion battery for a long time, discontinue it with a charge level of at least 40%. The battery will lose between 5 and 10% charge per month.

An important point to remember is that when lithium-ion batteries reach the absolute level of zero, they can become unstable and dangerous to recharge. So to guard against the risk of explosion, know that the manufacturers had the good idea to integrate a function of self-destruction to the circuit of lithium-ion batteries. So in case you forget a device with this type of battery, you can always try to recharge it, normally it will not work. But you will not risk finding yourself with an acid mask (due to a possible explosion) since your battery will definitely fuck.

Do not worry too much

It is easy to properly take care of its battery as it is easy to become lazy and not worry about the problem. But nothing serious, except in extreme cases, everything should go well between your lithium-ion battery and you. As a general rule, such a battery has a lifetime of three to five years and the reality is that you will definitely choose to switch device in this interval of time. Remain that leaving his smartphone to rest every night on a wireless charging base is more damaging than following the simple rules presented here. For more infor visit Uppward.com.
