Day 2 of 365 days battery eufy cam 2 pro

It’s 1am here and I’m awake because it gave me a notification that there’s someone in the backyard, freaked me out, but there’s none thankfully! Is it normal to be giving false alerts? Also it’s day 2 but it’s already down to 98% battery and it’s supposed to last 365 days?! How long did the same camera lasted for you before you had to recharge?
