I have an IPhone 8 on IOS 12 , which I have had for less than 3 months.
Lately, the battery has been going noticeably down quite a bit without me using it, and I'm not sure why.
I use Amazon music during the day but I download songs, I'm not sure if that factors as well.
I feel like I always need a portable charger with me, in order to make sure the battery life stays at a good level.
Is there something wrong with my phone, or do I need to do an update?
I heard lately there were bugs on IOS 13, but I'm not sure if that is solved now
