My new Nintendo Switch Lite battery dies fast
I've got a Nintendo Switch Lite Dialga & Palkia edition, I've got it yesterday. I downloaded Fortnite and started playing it, everything was normal at first but then the battery started to die fast.
I don't know anything about Nintendo Switch Lite.
How do I slow the battery?
According to the article https://www.tomsguide.com/features/nintendo-switch-oled-battery-life-tested , the battery of the Nintendo Switch Lite should last for more than 3 hours when playing a demanding video game.
If your battery only lasts minutes, then it is defective. You need to replace the battery, or even replace the entire Nintendo Switch Lite.
Ask for support from the vendor, and demand replacement or reimbursement.
