Battery Full Capacity is 84% of Design Capacity after 3 months in use

[Steve3009]

 Hi guys,

I just bought an HP envy notebook three months ago in Seoul, Korea.

After trying the battery calibration as guided on the HP official website, I found that the battery full capacity is 84% (43 Whr) of the design Capacity (51 Whr).

Is there anything wrong with my battery. Do I need to go the warranty center in Seoul to check for it? To be honest, I cannot speak Korean and Korean people rarely communicate in English, so I hope I can fix the battery problem on my own rather than go to the Korean customer center.

Any help would be greatly appreciated.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help,

To get the answer to this question, the Design Capacity is how much power the HP notebook battery could hold when it was boxed and Full Charge Capacity is how much it can hold now. The average laptop battery is good for around 400 recharged cycles. After that, it starts to lose its capacity to hold a charge.  Refer to the article Testing and Calibrating the Battery (Windows)

Hi Echo_Lake,

I appreciate your explanation. However, there is one point you mentioned that I still don't understand.

What do you mean by 'The average laptop battery is good for around 400 recharged cycles'? If I am not mistaken, my battery cycle count is just 21 now, which haven't reached 400. So why does the battery lose its capacity? And the fact is the capacity loses that much  (16%) just after 21 cycle counts. 

Could you please clarify further about this? 

Regards,

Steve

Thank you for posting back. 

Let's test the battery using HP Support Assistant:

To use HP Support Assistant to check and calibrate the battery, follow these instructions:

1. In Windows, search for and open HP Support Assistant.

   If the app is not installed on your computer, go to HP Support Assistant to download the latest version.

2. Select the notebook tab, and then click Battery. The battery page is displayed.

   

3. Click Run battery check.

Hope this helps! Keep me posted for further assistance.

Dear Echo_Lake,

The first time I run 'battery check' and the second time for the calibration, I saw no difference as mentioned in my first email.

However, I did the third check (the attachments) as your suggestion and saw a difference. It shows 97% of Full Capacity. There may be some magic that makes the battery work as normal ^_^. 

Anyway, I am so thankful for your willing support!

Regards,

Steve
