    Can anyone tell me how to check Laptop battery health ?


    Hey,

    I want to know how to check Laptop battery usage time as I see there is usage history and battery life estimates. Moreover, I want to know if my Laptop battery health is in good condition ?

    Battery Health was 88% and after doing battery Guage reset its now 78.4%.

    I don't know if this Battery information will interest you. It contains a LOT of useful information [ taken from one of my Scripts ] that you might find useful.

    Copy & Paste the following into a CMD Prompt and press Enter . . .


    Battery Information::-
    Code:
    
    echo. & PowerShell Get-wmiObject Win32_Battery ^| Format-List ^
         @{L=' Name'                         ;E={;if([string]::IsNullOrWhiteSpace($_.Name))                        {'N/A'} else {$_.Name}}}, ^
         @{L=' Description'                  ;E={;if([string]::IsNullOrWhiteSpace($_.Description))                 {'N/A'} else {$_.Description}}}, ^

    Whilst there is no formal definition of battery health, the generally-accepted meaning is the ratio of
    Full charge capacity / Design capacity.

    In your case that is 78%.
    So you have only used up 22% of its potential lifespan.

    Hello,

    In addition, you could generate a battery usage report below to help learn more about the health of your battery.

    Can you check and tell me:

    Btw I dont understand this: Battery Health was 88% and after doing battery Guage reset its now 78.4%.

    The main thing is to look at your Battery capacity history from the report to see how much "full charge capacity" you currently have left compared to its original "design capacity".

    From your report below, you have lost some capacity which is normal over time, but it's nothing to worried about. It's needs to get much lower before you need to think about replacing the battery.

    As you can see on 27-June-2022 it was 46,220 mWh where Battery Health was 88% and after doing battery Guage reset its now 78.4%.


    On battery guage reset why charge capacity lost I dont understand this till now.

    It's normal for it to fluctuate some, but not sure why it dipped like that after doing the battery Guage reset. Hopefully, it will not dip anymore like that soon.

    The shop I purchase this laptop he said he can replace the battery with other x1 carbon battery. Which have battery health 82% but if I do battery guage reset that battery I am assuming it will go more lower than 75% and I am not sure about how many cycles it ran. So, I am thinking to keep my laptop with this battery. What do you suggest ?

    I've seen sudden drops in my own batteries of up to 8%.
    In addition, I have never seen any estimation of accuracy for any battery measurements. When I was investigating power use during S3 Sleep, I discovered that the %-charged icon in the Taskbar SysTray ["Notification area"] can have inaccuracies of 3% so it might be that all battery-related measurements are similarly inaccurate for all any of us know.

    I agree with you. There's no persuasive argument for changing it.
