The battery is NOT being calibrated, just as there is technically no such thing as a router that is wireless.

But just like ' wireless router' it is technically inaccurate. Is it safe to use the laptop while it is plugged in Here, youll find the answer to this question with the pros and cons of using a laptop while charging. I accept that the expression ' battery calibration' is a term that is here to stay. It may be more a matter of semantics but that illustrates the bigger problem - marketing weenies using technically incorrect terminology in user manuals and product promotion materials - again.Ĭalibration suggests some type of precision. I also want to know exactly how long before I reach 100% charge - which, if I am idle should be fairly easy to accurately foretell. When I am using my notebook, I want to know exactly how much battery run time I have left - especially now that my notebook battery is 8 years old! Yes, I realize that will vary depending on the task(s) I am performing now, but I'm okay with that. It is just being reset and 'synchronized' to reflect some other uncalibrated value. The only danger is your notebook running out of battery too early.Ĭlick to expand.So what reference standard is that gauge being calibrated against? Some sensor that cost 2¢ to make? What reference standard was that sensor 'calibrated' against? The gauge is not being 'calibrated'. So if not properly 'calibrated/synchronized' there is no danger of overcharging (assuming the battery is not defective).

It is the battery that prevents overcharging, not the charger. It just takes longer with a trickle charger. Larger laptops with multiple GPUs even have more than a single power brick, requiring two. This is why a 'trickle' charger can fully charge a battery to 100% as can a high capacity charger. Some laptops actually require you to game while having it plugged in, especially gaming notebooks. Note that batteries pull from the charger what they need, as limited by the charger's capability (just like a computer pulls from the PSU what it needs, not what the PSU can deliver). That results in a reduced run time and/or the notebook shutting down when it still showed 20 - 30% (or more) charge left. The problem is if the notebook thinks the battery is fully charged, it can shut down charging too early. It does not affect the charge rate in any way - the battery's own internal circuits do that (as happens with all batteries). It just 'synchronizes' the battery's charge and time remaining to the notebook's monitoring and status display. I wish whoever decided to call it 'calibration' didn't.
