Hello,
I just installed graphene on my new P8 pro - was previously on Calyx on my old phone. After the first day, I noticed my battery was drained. Looking further, it seems that my browser app of choice, Fennec (from F-Droid) is the culprit, using 48% of my battery. I don't understand how this app can be using this much battery? I even disabled background data AND set the battery profile to "restricted." Even then, it someone is telling me that it's burning up my battery. I switched to the default browser today and I'm not seeing even close to the same battery drain, so it's definitely something with Fennec. Anyone have any thoughts? Never had this issue on Calyx so I know it's not the app. Thanks!
