Black screen

Since i installed iOS 18 beta, my iPhone (15pro) battery % was very very very fast going down and yesterday (23 June) my phone started being VERY lagged and being in black screen. It logged me from apps like TikTok, Facebook, Instagram and my own Apple Account. All the time i was on low power mode, so i turned it off and i think its better now, no lags no black screen happend yet
