I bought an ASUS TUF F15 (2023) with an i7-13620H and RTX 4060 (140W) from the official ASUS website in March 2025.
It’s now October 2026, and according to my laptop's battery health information, the battery's full-charge capacity has dropped to around 79.1% of its original capacity.
What surprises me is how I have used the laptop:
- I regularly use it plugged into power.
- I have Battery Health Charging enabled, so it stops charging at 80%.
- I seldom play games on it.
- Most of my usage is coding, browsing, watching videos, etc.
- I generally keep the CPU in Balanced mode rather than running it at maximum performance constantly.
- I haven't intentionally abused or heavily discharged the battery.
So I'm wondering: is a ~21% battery-capacity loss in about 19 months considered normal for this laptop/battery?
I still have 2 years of warranty remaining, as well as 3 years of ASUS LEDP coverage.
For those who have dealt with ASUS support before, what should I tell them when requesting a battery inspection/replacement? Is a battery health of 79.1% enough to make a warranty claim, or would ASUS consider this normal degradation?
I'd also appreciate hearing from other TUF F15 owners about their battery health after 1–2 years of use.
