XPS 13 9370, battery degradation
Within one year my XPS 13 9370 battery is reporting a 63.9% capacity. Under normal usage with CPU frequency scaling at power save, screen dim just above minimal, fan usually off, this gives me just 2,5 hours without charger. This does not seem normal to me. I only use the Dell TB16 docking station and Dell charger for charging. Does anybody have similar experience?

This Dell support page will give you more information. Dell states that battery life will be reduced after 18 - 24 months. But if you are a power user it could be less.

Thank you for your reply. I already saw that page. It states:
"Normal characteristic of a rechargeable battery is that the charge capacity reduces gradually with each discharge-charge cycle. Typically, you will notice reduced battery life after 18–24 months."
It does not say what 'noticeable reduce battery life' means. Is that 10% degradation, 40%, or a 100% degradation? 100% I would notice for sure, 10% I would most probably not notice, 40% is noticeable for me.
I know that batteries degrade over time and especially with many charge cycles. Thing is, I usually do not discharge and charge, since the XPS13 is connected to the TB16. I only occasionally work at other places where I need to have a few hours of battery.
It is advertised as having 12+ hours of battery charge under normal conditions. Some browsing, some text editing, screen dim, no sound, WiFi/BT on, PowerSave on, seems to me as normal usage. 2.5 hours is nowhere near those 12+ hours advertised.
Almost 40% degradation is far more than noticeable reduced battery life, and 11 months is much shorter than 18-24 months.

Battery degradation is a common concern for laptop users, including those with Dell XPS 13 laptops. Over time, laptop batteries lose their capacity, which means they can hold less charge and need to be recharged more frequently. Here are some tips on understanding and managing battery degradation:
Understanding Battery Degradation:
Use Battery Saver Mode:
Optimize Power Settings:
Avoid Extreme Temperatures:
Partial Discharges are Okay:
Calibrate Your Battery (Occasionally):
Reduce Background Apps:
Limit Charging to 80%:
Replace the Battery:
Battery Health Monitoring:
It's important to note that battery degradation is a natural process, and while you can take steps to slow it down, it cannot be completely prevented. However, by following these tips, you can help extend the lifespan of your Dell XPS 13's battery and maintain its performance for longer.
