Although it is normal for battery capacity to decrease over time, I would run a 'manual' calibration. By that I mean let your battery drain right down until it is no longer capable of powering your laptop. Then plug in the power lead and let the battery fully charge to maximum (without using the computer). So, plug it in until it charges 100%.
Battery cells suffer gradual, irreversible capacity loss with each discharge-charge cycle. Temperature and discharge loads can impact battery performance and capacity. Battery capacity and charge can decrease even when the computer is unplugged from a power source and not in use or turned off. The amount of decrease can vary by computer model.

If your HP 15 laptop's BIOS has detected a reduced capacity of the internal battery, it means that the battery is no longer holding its full charge as it did when it was new.
If your HP 15 laptop's BIOS has detected a reduced capacity of the internal battery, it means that the battery is no longer holding its full charge as it did when it was new. This is a common occurrence with laptop batteries over time, as they have a limited number of charge-discharge cycles before their capacity starts to decrease.
It's not uncommon for laptop batteries to first degrade slowly, then suddenly much faster. It means the battery is near the end of it's life. If you're planning to keep the laptop, then it's time to get a replacement battery. Typical Dell laptop battery. It's probably a coincidence that it occurred at a similar time to the update.
Replace the Battery: If the battery capacity reduction is severe and it no longer holds enough charge to meet your needs, it might be time to replace the battery with a new one. Laptop batteries are replaceable, and you can usually find compatible replacements online or through authorized HP service centers.
