Well, right now this is only speculative. If a bug does exist in WebKit, then you are right. However, a bug could still exist in safari that does not directly tie into the WebKit api, then using a different browser may make a difference.

Battery issues on iOS 14.6? (iPhone 11 Pro)

This is purely speculation but my money is on something in WebKit causing the drain, since for a lot of people, myself included, battery drain started with 14.5.1 which was the emergency release for the active WebKit exploit. I’m guessing changes that were made to fix the vulnerability introduced this issue.
I ended up restoring my phone and not applying a backup since most things are on iCloud and I get it all back by logging in. I've only downloaded a few of the apps I had and haven't set up all my settings, but it's been almost 7 hours off charger with some minimal use (less than 1 hour) and I'm at 98%. Seems to be spectacular battery life so far. I'll see what happens after downloading more of the apps I had and changing settings.
The battery is really no longer the same after iOS 14.5 and 14.6. Before I arrived at the end of the day with 50 to 60%. After these updates I arrive at the end of the day with 30% more or less with 4h and 30min of screen on time.
Tried 14.7 PB3. So far subjectively seem to be back to normal, but it’s still too early to tell definitely.
So 24h later doing the same as usual (browsing / some game, etc.), I was on 20% battery still. That definitely seem better than before with 14.6. where I had to charge in the morning and evening.
After some weeks with iOS 14.6, I can tell that the battery is finally back in its good performance levels.
Seriously the iPhone 12 mini is the most amazing phone i got in my entire life i really love it
i do not use the phone a lot while working, it can last me two days !

XR here - nothing special use, certainly no different (or added 3rd Party apps) than earlier OSs, and I'm finding that I'm down to the 20% warning before the afternoon is over. And Settings > Battery suggests once it starts to go, its a precipitous drop. Pretty terrible. Taken to stuffing an external battery pack and cable into my bag if I'm out for any length of time.
Thank you for doing this. I've been considering the same on my iPhone X which still has dismal battery life (with a new battery) but have hesitated because of the work involved.
Just so I understand, did you do a factory reset of the phone and then log in to iCloud?
And what has your experience been when installing apps and applying settings? Have you perhaps identified one or several apps as the battery thief/-ves?
Thank you very much in advance,
Philip

Yes, factory reset so that you're starting on a fresh install. Don't restore from backup. Of course you'll want to be sure everything is in iCloud so when you log in, everything comes back.
I still don't have all my old apps installed since I didn't end up using them, so I can't speak to whether it was one bad actor. My battery life is definitely still better than post iOS 14.6 install.
For settings, don't think anything is different. I did decide to leave background app refresh on (used to be off) and it doesn't seem to be causing issues for me.
Thank you very much for explaining. I will try this later in the week. I have in the meantime updated to 14.7.1 but see no improvement at all. The phone hits red in the early afternoon having only been on wifi and barely been used.
I'll also try leaving background app refresh on after I've reset the phone. It was one of the first settings I turned off to save battery but perhaps it doesn't actually use that much.
