battarey life span discussion

[RyokSec]

Hello all i usually use my laptop (paviloin x360) almost all the day long and i am concerned about its battarey so i have a question what is the best way to make your battarey life span longer ?

what i do right now is that i unplug my laptop when it is 100% and use it untill its 20% then i usually plug it again and use it untill its 100% then i unplug it and repeat this cycle

is that good or bad and if its bad please guide me about the best way to keep my battarey in a good shape for a long time

@RyokSec 

There is a lot of discussion on the subject.

One viewpoint:

The number of times a battery is discharged / charged (cycles) can affect the overall lifespan of the device.

For example, if you leave your computer attached to AC power all the time, the battery suffers fewer discharge and charge cycles.  Fewer cycles might translate into longer battery lifespan.   

Is that true?  Fewer charge cycles = longer overall life?

I do not know.  I do have a four year old Zbook 17 G3 that runs on AC power most of the time - the battery (admittedly a robust monster) still charges to between 96-97%.  This comparison might not even be relevant - a Zbook workstation is not a Pavilion or a Spectre.  The Zbook charge system is in some ways different from that of a consumer grade system. 

What else?

Note that leaving the battery plugged in after it has reached the highest capacity to which it is capable does not cause the battery to last longer when the computer is run on the battery.  The amount of time the battery lasts while the computer is running on that battery varies by battery condition, battery specification, and how the battery is used.  For example, viewing email and watching streaming content or playing games are different activities and require different amounts of resource from the battery.

Below is the usual content that I include when someone has a problem with their battery / charge system.

I understand that you are not "in trouble" at this time.

The content does include some interesting bits, including an article on battery technology (how it works), and some tips on where (and what) to check when the battery is not performing as expected.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

Battery seems “stuck” in a particular charge setting         

The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:

i have two questions after seeing the links 

true or false 

1- the best way to use your computer ,is to charge it to 100 and use it untill it hits 20 or 25 and do that again ?

and if it is true then 

2- does using the computer while it is charging affects the battarey life span a lot or not ?

the activities lets say watching movies and programming 

thanks in advance

[Dragon-Fur · Accepted solution]

@RyokSec 

1. I am of the opinion that leaving the computer plugged in when possible is fine and this is what I do.
2. I do not believe using the computer while it is plugged in and charging has any impact on the life span of the battery.

I do not watch movies on my workstation, though I do use it for home / house design.  As a project progresses and becomes more complicated, the system does have to work a bit harder to provide the necessary resources.  I always work on design projects with AC power connected - the work is to too important to slow down while running on battery or to worry about resources.  

Movies and streaming also put a strain on resources - I would leave the computer plugged in during this type of activity when at all possible.

I am retired IT - my programming days are long past.  Smiling.

Caveat

My opinions about any system in terms of performance, including battery life, are biased.

Smaller, less expensive, consumer grade systems are not built to the same standards as fully loaded workstations and other top-shelf business class systems.  If consumer grade computers were built to the same standards, consumer grade computers would cost as much as fully loaded workstation.  

What does this mean?

Expect the battery to last as long as the warranty - perhaps maybe even as long as a couple of years.   In fact, if the battery lasts the one year standard warranty period, that is (in MY opinion) about what you can expect.

Expect to upgrade your hardware every so often.   For example, as much as I love my workstation, it is four years old this month.  Time to move on.  Thinking on the replacement.

The less you spend up front, the more often you may need / want to upgrade / maintain / change your hardware.

Again, I am biased.  I moved to Business class machines a few years ago and never looked back.

Different animals.

Most important of all - I know a little bit about battery technology.  Not much.  A little bit.  Not an area of expertise.

Stay Safe.
