My cellular strength is very good in my area, and yes, I have Wi-fi Voice calling enabled.
I'm not sure if I do have any of these enabled. I did disable diagnostics during setup etc.
Plug your iPhone into iTunes. Click Restore. When it finishes, set it up as new and do not put a backup on. As you are downloading your apps and stuff again, don't judge battery life. That takes a lot.
Now that you have a clean phone, go into settings, go to privacy, location services. Turn off motion and fitness if you dont use it. Turn off what you don't use. Go to mail, go to mail, go to fetch new data, turn off push, turn fetch to whatever you see fit. Lower times gives better battery. Turn on airplane mode and then turn on wifi when you are home and on wifi. wifi calling will kick in so you get all calls and texts still but since airplane mode is on, cellular radio is off, preserving battery. Go to settings, go to icloud, turn off icloud drive if you dont need it. Turn off icloud photo library if you don't need it. Go to settings. Go to battery. Turn on low power mode. Lastly, turn your brightness down to 50%, maybe even 30%. If you are still complaining, exchange the phone.
This is like neutering your phone but that's the best you can do for battery life. Also don't play any games and don't use any social media
If you turn off cellular while at home and let Wi-Fi voice handle it that's one less radio operating while at home. Just a thought.
Read the articles I previously attached, there are a number of features you can turn off to reduce power usage. If it's a feature like motion that you don't actually use, why have it consume battery. Also, what do you keep your screen brightness at? Unless I am outside in sunlight I don't need or like the screen too bright.
He runs at 100% brightness. He ran at 100% as well on his regular 6S. He's getting not as good battery life with 100% brightness on the plus now, or at least not as good as he expected. I think he was expecting like 8hr use with 100% brightness but no matter the phone, that is not going to happen, sorry. Maybe if you have like 30% brightness.

Read through the remaining of the topic aside from the first few posts. I sent it back, received a new one, and set it up as new.
I know the second bolded statement, however, even when others post what battery usage they're getting and claiming they use 100% full brightness, my stats don't even come close.
Going to post a new 100% to 0% and post stats here.
Oh okay sorry I missed that part. I have a post up instructing you to set up as new/exchange, ignore it. I posted that right before you posted this.
