Hello,
I was advised to fully drain my laptop battery as it might solve a problem.
But if I plug in my laptop and let the battery deplete normally, at 7% it automatically goes into hibernation.
So how do I do it?
Thank you for your responses.

I had a problem with my battery charge indicators (light and battery icon on the desktop), basically: when 100% was reached, the light didn't change from orange to green and the icon said "100% - charging" instead of "charging complete (100%)".
We talked about a "calibrated gauge".
Then I was told to completely discharge my battery to 0%, then recharge it all at once.
Basically like in your article, except he told me 0%. -.-
"Calibration: this process involves 'reframing' the full charge of your battery. To do this, when the battery is completely discharged (not below 10%, but when the OS puts the laptop in sleep mode), it must be recharged fully without interruption. This actually allows your battery to undergo a full discharge followed by a full charge, which maintains it. It is recommended to do this process 1 to 2 times a month."

It actually allows your battery to undergo a complete discharge followed by a full charge, which maintains it. It is recommended to perform this operation 1 to 2 times a month.
"complete discharge"
I would have preferred it to say "a deep and controlled discharge."
"which maintains it"
It does not maintain anything at all.
On the contrary.
Deep discharges reduce the lifespan of accumulators.
"It is recommended to perform this operation 1 to 2 times a month."
Certainly not.
Only to be done when in doubt about the calibration of the system that manages the battery.

Hello "Coincoinwcbiensur".
And avoid making big mistakes.
We really read all sorts of things on this subject. Some people deserve a slap.
Charging and discharging
Charging usually occurs in two phases: a first phase with limited current of about C/2 to 1C (C being the capacity of the accumulator).
This phase allows for a fast charge up to about 80%, followed by a second phase at constant voltage and decreasing current to get closer to 100% charge in about 2 more hours.
Charging is completed when the charging current drops below a value called the end-of-charge current.
The end-of-charge voltage for Li-Ion accumulators can be 4.1V or 4.2V depending on the manufacturer's specifications.
The commonly accepted tolerance is +/-0.05 V per cell, they are very sensitive to overcharging and require protection when connected in series.
Chargers must be of good quality to respect this tolerance.
It is important to always follow the data sheet provided by the manufacturer, which states the charging conditions of the accumulator (tolerance, charging current, end-of-charge current, etc.).
However, some consumer-grade cells have built-in electronics that protect them from improper handling (overcharging, deep discharge).
Indeed, the discharge must be limited to a voltage of 3V per cell, a discharge voltage below 2.5V can lead to the destruction of the cell.

I recently learned about li-ion batteries that the best charging range is between 20% and 80%, which would be ideal to keep the battery healthy! ^^
Now you know about the 20%, but why 80%? Well, I don't know if you've ever noticed, but when you charge your phone, it charges quite quickly, the percentage goes up relatively fast… until you go beyond the 80% mark! From that point on, the battery seems to charge much more slowly. During this time and until it's fully charged, there may be a slight overheating, which can degrade its lifespan a bit.
Why do you think that when we buy a phone or a PC, for example, the battery is never completely charged or drained...
(Pssst! Once you've sorted out your little issues, don’t run away!

Hello everyone!
Back after six months, I finally found the link I stumbled upon by chance that talks about charging and discharging Li-ion batteries for laptops, but it's the same for smartphones and other devices with the same type of batteries.
So here it is:
Charging and discharging your battery
... The page of the link and the next two being the most interesting regarding this post.

Hello,
Who is the idiot that told you to do that?!! If your PC goes into hibernation, it's for a reason; a battery should never be fully drained, especially the newer ones, or you'll risk killing the battery, or at best, drastically shortening its lifespan! ...
But by the way, why would you need to drain your laptop's battery, how would that solve a problem? And what problem, while we're at it? ;)
