I have an IPhone 12 on 85% battery health(I will upgrade this year). I’m going to get the Apple battery pack for $15(I got a seller). It’s brand new so no issues but will it affect my IPhone? I was told it’s kinda unsafe with the heat and lowering battery health. I don’t plan to use it everyday if I have a charger, just on the go. Also, I will appreciate if y’all give me ideas for a new and better Battery pack that I can upgrade to later
