Battery Capacity is 33% of orignal in just a year

[fez15]

Hi, when I started my laptop, I get this message about the battery, right before bios or right after it, that it is not useful anymore.

So I continued the startup and ran the HP battery check-up. It also said that the battery is weak. 

According to the details, it says - 

Warranty Type - 3

Cycle Count - 192/1000

Battery Age - 529 days

Temperature - 31 degree Celsius 

Design Capacity - 3615 mAh

Full Charge  Capacity- 1221 mAh (33%)

Now, I have bought this laptop on 22nd October 2018, which is almost a year ago. 

How in the world would this happen, and to right after my base warranty is over?

Note -

This laptop is up to date with all the drivers and system updates, even the latest bios as of today(16th November 2019) 

Bought it from HP authorized dealer.

@fez15 Welcome to HP Community!

As the battery is a consumable part the life of the battery decreases each time you charge your laptop.
 
Factors that contribute to the loss of battery capacity.
 
Li-Ion battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle. Such aging occurs more rapidly as temperature and discharges loads increase.
The self-discharge rate of a Li-Ion battery is higher if the battery is left in an unpowered notebook.
During prolonged storage or non-use, the battery charge will decrease below its recommended low-voltage level.
Leaving the battery in a depleted condition for an extended period will accelerate the decrease in FCC.
Leaving the battery at a high level of charge in a high-temperature environment for extended periods (for example, running a notebook computer in a docking station under a heavy load) will accelerate the loss of capacity.
Running high-end applications using the battery accelerates the loss of capacity. For example, playing 3D games will lower FCC faster than using word processing applications.
  

However, you can try the steps recommended below.
 
Open Power Options on Windows 10.
Click Change plan settings for any of the power plans. I would suggest you choose the power saver plan.
Now click Change advanced power settings.
Under the Advanced Settings tab, scroll down to find Processor power management.
Now, expand (click on +) Processor power management.
Expand the Maximum processor state.
Click the On-battery option and reduce the processor state to 20%. You can choose any other value.
Click Ok. The settings are saved, you can close the Power Options window.

Enable Adaptive Brightness
Go to Power Options select change advanced power settings
Go to the Change advanced power settings. Expand Display> expand Enable Adaptive Brightness. Now, turn on Adaptive Brightness for On-battery and Plugged in options (whichever you like. Click Ok to save the settings.

If the issue still persists try uninstalling the battery drivers device manager.

Search for and open Device Manager.
Click next to Batteries to expand the battery options.
With the options expanded, right-click each ACPI option and in the menu, click Uninstall.
Restart the computer.
The battery should now charge properly.

Please ensure you update the bios, chipset and graphics drivers from this link: http://hp.com/drivers  Please select the country and type the product# of the unit. Then follow the on-screen instructions.

Also, download and install the HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Hello, @praveen196 and @olärsonn

I have been testing my battery for 3 days (16th, 17th, 18th Nov 2019) the same way, i.e. through the HP support assistant and for some reason I have gotten better results, around 75% of the original. 

I have uploaded the screenshots, for the time and date please check the bottom left corner.

I also tested through HP PC Hardware Diagnostics and it passed.

As of today, the battery capacity is 73% says the test. 

PS: I have not updated anything for the past 4 to 5 days. The BIOS was already up to date.

So, should I assume that this was just a software fluke?

So, my laptop drained completely when it showed 62% while I was using it. It was hibernated and after charging it a bit I did some tests.

All this time the BatteryMon application was running.

Here are some screenshots.
