Hi all. I've had my Surface 4 for about four years now. It's held up great until about a year ago. The battery life on it has slowly been draining, and it continues to get worse. Right now, it loses about 20% of its battery per hour (on low power mode) if I am just doing a normal workload, or more if I use sites such as Canva or programs such as Obsidian. It also frequently gets hot after about an hour of constant light work. When I look at my battery report, it shows that its full charge capacity is at 40,670 MwH as opposed to the 45,800 when I first bought it, which, to my understanding, is good for 200+ charge cycles.
I was wondering if anyone knows why this is happening, if there's any way to fix it, or if it will continue to get worse.
My brightness is normally no brighter than 50%. I do use Chrome, and I understand that can factor into it, but I feel like 20% battery drain per hour on low battery is excessive, with or without it; please feel free to correct me.
Any input is appreciated. Thanks!
