Replace the battery in your Dell XPS 15 9520.
The battery's life shortens gradually. Despite being marked as functioning well, you should check your BIOS settings. Certain laptops include a configuration that restricts how much a battery can charge, which could explain why it only reaches 50% even for older batteries.
You're asking if the current percentage still matters. The battery is currently at 50%, and while some guidelines suggest lower percentages are less critical, overall health and performance still depend on reaching a full charge. It's not just about hitting a specific number—it's about maintaining consistent usage and avoiding stress.
There seems to be no built-in feature to display the number of cycles used. If you've kept the laptop running continuously for a long time, it might be worth checking the manufacturer's documentation or contacting support for specific guidance.
