A few years ago, we were used to having laptops with external batteries that can be removed and therefore changed quite easily and, above all, economically.

Today, however, the situation has changed. In fact, batteries are now integrated into computers and to change them, you either have to know how to dismantle this type of machine yourself, or go through a professional and there, the bill can quickly become steep.

So, his laptop, it is better to take care of it rather than something bad happens.

In this article, we are therefore going to tell you what you absolutely must avoid doing with it to make your battery last as long as possible. Let's not waste a moment and let's go!

Sudden changes in temperature

Often when we have a laptop, quite logically, we will take it almost everywhere with us. But although it seems logical, you need to take some precautions when transporting your computer.

Indeed, if too much heat or on the contrary too much cold will have effects for us, this is also the case for the battery of our computers which do not really appreciate going to extremes in terms of temperature.

Therefore, what we will advise you to do is to buy a carrying bag for your laptop. This will insulate it from the cold in winter and prevent it from being directly exposed to the heat of the sun in summer.

Likewise, when you carry a laptop, we advise you to turn it off first. So once you arrive at your destination, let it cool or warm up a bit before turning it on. It's very simple and it doesn't ask much of you, but you will be able to save your battery over time.

Letting it constantly charge

Often when we have a laptop and we are in a place with a power outlet, we tend to do one thing, leave it constantly plugged into the mains and this for several reasons.

We can, for example, speak of system performance which are generally better when you plug in your computer. We can also talk about the fact that it's less annoying to let it charge continuously, rather than plugging it in and unplugging it at regular intervals.

However, by doing this, you damage the battery from your laptop. Indeed, very often, by not taking the time to do a normal charging cycle, you will destroy your battery at high speed.

This may seem completely counterintuitive, but it is indeed the case and perhaps you have already had the experience of a laptop that has almost no battery life even though you have never used it. In 99% of cases this is why you have problems!

Not managing your battery

We just said, let plugging in your laptop for too long sessions while it is already loaded, this is one of the biggest mistakes you can make and many people make it.

But you should know that a laptop battery can be managed and that there are a few rules to follow if you have a power outlet nearby. Obviously, if you are in nomadic mode and without a way to charge your computer, these tips do not apply to you.

But if it is possible, you should know two things. The first is that you should never recharge a laptop that has more than 80% battery. Indeed, it is better to let it turn and descend in battery than to constantly want to enter too high.

Likewise, you should never let it drop below 40% battery if possible because it is from this limit that your battery will start to be damaged. In summary, if you have a power outlet available, here is the procedure to follow.

  • When your computer is charged, unplug it.
  • At 40% battery, plug it in.
  • At 80% battery unplug it again.
  • Repeat the previous steps.

Some laptops allow you to limit the charge percentage to around 80% to extend the life of your battery. This feature is supported by specific manufacturers using their own apps, such as MyASUS for ASUS users and the “Battery Limit Mode” setting for Microsoft Surface users.

Other users can download the free Battery Limiter app for Windows.

Discharge your battery from time to time

We have just told you, a laptop battery, if you want to preserve it over time, you will have to make it cycle as precisely as possible. From then on, you were told not to let it fall flat if possible.

Except that at times, it is still better to make him do a full charge and discharge cycle. This is therefore a little counter-intuitive to what we were telling you and that is why we are going to explain everything to you here.

In the vast majority of cases, you should not go so far as to discharge the battery and you will therefore have to follow what we gave you as a tip just above. However, from time to time, Doing a full discharge is important.

Indeed, if you do not do this, your battery may be a little lost and no longer charge properly. Thus, you might have problems if you never unload your computer.

As for the frequency with which you will have to do this manipulation, we advise you to do it about once a month. Like this you save your battery while saving you problems in the future.

Conclusion

That's it, you now know our tips and tricks to be able to conserve your battery over time. The main thing to do is therefore to manage the charging cycles to avoid typing too much into it.

The second thing to do is simply to avoid excessive temperature variations which can also quickly damage your batteries. However, we must see one thing that remains inevitable.

Indeed, even if you religiously apply all these tips, your battery will eventually wear out. As it is used, its autonomy will decrease, but by applying all these tips you should be able to guarantee yourself a few years of peace of mind.
