Yeah man, I'm still struggling with the battery life of the 12Pro.... I just expected more. My X is still at 96% capacity and I almost feel like they're about the same in battery life.
PRO TIP: I find that if you keep your screen brightness at the LOWEST setting when you're not using the phone AND you try your hardest
NOT TO USE the phone
AT ALL that the BATTERY LIFE IS GREAT!!!

Side note: I'm going to stick to using the MagSafe charger as much as I can. I gave my phone the slightest hair thin speck of a scratch from "plugging" in the USB-C port in the dark.
