My iPhone 7 had horrible battery life, I needed to charge it before 6pm even barely using it. Did loads of testing, CoconutBattery said it would charge to 100% of its original capacity. I got my SO old 6S and started comparing it, without usage or networks the 6S would last up to 5 times more than the 7. **The main issue was that the phone would lose a lot of battery even when turned off. In 24 hours 40% of the battery was gone, even with the phone turned off.** [Here's proof.](

The nearest Apple Store is more than 1000km away. I sent it to Apple via mail, they received it at 5 PM and returned it on the next day, at 9 am with a letter saying everything was fine.
So I took it to a local AASP (Apple Authorized Service Provider), after 4 days of testing they too said the phone was normal. **The advantage was that I could talk directly to the technician at the AASP.** I called her Saturday and she explained that the phone was getting 8 hours and 38 minutes of usage (which is a lot less than the [12 hours of 3G Apple claims](
http://www.apple.com/iphone-7/specs/), but still). I asked her to do one more test: during the Saturday charge it to 100%, turn off and check the battery level on Monday, when she returned to work. She agreed and said it was expected to have at least something around 80% of battery.
I called today and she said yes, the phone's battery has an issue, but since Apple's test does not detect it she can't order a replacement right away. She contacted Apple directly, explained the situation and Apple said that they wouldn't replace the phone. This is the weird bit: she said they requested for a replacement anyways since they're aware that there's an issue in the iPhone even though Apple tests cannot diagnose it. I don't know what that will result to them, all I know is that in 7 days a new phone should arrive.
Well, that's a very good end for me. And a big thank you to the AASP Soma at Porto Alegre, south of Brazil. Amazing service, can't thank them enough. Next week when the phone arrives I'll have a thank you gift for them.
This happened on a 50 days old iPhone 7. I had tested two other iPhone 7 (SO and Brother-in-law), they didn't present this issue. Both are Silver 128gb, mine's Matte Black 256gb.

[doublepost=1481836399][/doublepost]Posted my experience at
reddit, I'm also posting it here because felt it could be relevant.
TL: DR: Apparently Apple's test does not identify incredibly short standby time in iPhones, only total battery capacity.
There's ton of posts about iPhones battery, but I couldn't find any issue exactly like this one in reddit. I thought sharing what happened to me could help some of you.

There's another user at reddit with the same issue, but in a iPhone 7+.
So, if you're getting horrible battery life test it like this:
1) Charge up to 100%, "close apps", turn on airplane mode and restart it.
2) Remove from charger, leave it alone for 8 to 12 hours (while you sleep) and check battery. It should hold the 100% mark or something close to it,
like my 6S.
If you get different results I would restore it as new, without logging in iCloud or using backups and repeat the test. If you still get significant battery drain (
like my old 7, more than 10% in 8 hours) I would go to Apple, try to explain it as much as possible and try to get a replacement.
