Returned my 7+ bc of this was gonna try again sometime next yr. with standby and everything off it drained 10%. Mind boggling. All the tricks people say wont work even DFU restore. Not sure why it does that. It does seem to be software tho.
Got a tip for us?

iPhone 7 battery life

These things are really strange.
The SE in our house drains 4 percent in a night (like from 84 to 80, from a 100 it stays on a 100). The 7 drains 7-9 percent overnight. Both are idle for 8 hours. What's more; the SE has 3 minutes of usage while the 7 gets around 30 minutes of usage overnight. While IDLE. Checked both batteries with coconut on a mac; the SE's is at 87 percent capacity while the 7 is at 104% capacity. So it's not a hardware problem.
Even with both phones on airplane mode nothing changes, so the SE is better at this stuff while the 7 is doing all kinds of crap. The 7 is connected to a Watch though (which seems to get 8MB of data for music pushed to it and deleted all the time, but that's a different problem)
Go full airplane mode(unconnected to AW)with DND on and see if it drains overnight. It still did for me. So weird
Iphone 7 plus
Havent used the phone for 20 hours. Here are my stats. During the typing of a few messages online de percentage dropped to 80 percent already. I really want to find the reason for so much phantom usage.

I'm Not sure if it's software related or faulty hardware now.
My own iPhone 7 drains around 2% per hour on standby with pretty much everything possible turned off. We have another iPhone 7 here set up the same with the same ios10.1 but that only drains around 1% every 2 or 3 hours on standby.
The phone that drains was set up from a iCloud backup of a 5s and the phone that doesn't was set up as new. So assuming it was down to this I thought I'd bite the bullet and do a full DFU restore yesterday and set up as new phone. Well this has made absolutely no difference at all it still drains 2% every hour on standby and I don't see how this can be software when it has a complete pure clean reinstall of all software/firmware via DFU mode set up as a new phone without most of my old apps installed on it yet. The phone that doesn't drain is running the same software/firmware, is the same hardware (intel version iPhone 7) and actually has more apps installed and more background stuff switched on.
My conclusion is that if a DFU restore and set up as new phone doesn't fix the standby drain problem it's a faulty phone and needs replacing. I wonder is Apple will accept this and swap it?
Edit: Just to add if anyone with an iPhone 7 with no standby battery drain issues could check cpu usage on the battery life app with all other apps closed via app switcher first .. here's mine on the iPhone 7 that suffers 2% battery drain per hour ..

Been AFK from this group ever since upgrading to the 7+ (Much better battery) but I've noticed something funny with my 7.
Wiped it over the weekend, put it on charge and once it hit 100% took it off and put it away. Turned it back on a day later, it's on 10%.
Hmm..
Luckily I've sold the phone, and if the buyer notices anything funny just get a free replacement, easy.

So how does that look on the non-drain phone?
It flutters between 5 and 20 percent here all the time.
Unfortunately I won't have access to the non drain one again untill Saturday now.
Mine that drains fluctuates mainly between 8% and 12% with occasional higher spikes, so your 5% minimum is a little better .., the lowest I've seen is 7% on mine.

you'll have to install the battery life app from the App Store

I honestly think that's normal. I will open that app on my GF's SE tomorrow; she has OUTSTANDING battery life (like 4 days outstanding with normal usage count).
Alright; just tried running the battery app while on power; on power (plugged in) it doesn't go under 10 percent, sometimes 7 as you said. When I take the charger out and wait for a bit it settles at 5-10. I guess this is normal behaviour; the phone is allowed to use more cpu-time when powered.
Also interesting; I put the phone in airplane mode and checked my usage times; they where at 4:40 at the start. After 10 minutes is was at 4:45. After another 10 minutes it was at 4:45, then after another 10 minutes; 4:45. Interestingly; the "drain" seems to be a process that needs to finish a task of some kind and doesn't repeat itself without a connection.
My battery is still rated at 2020MaH, which is more than the 1960 the battery is rated at, so NO hardware fault here. Maybe I'll try using xcode to take a look at things later, but the activity monitor seems to be taking up the most cpu time when I tried that before with other processes not being very interesting at all.

Here is what I get straight after an reboot and closed all apps.
This is sick stuff to watch at, no wonder my Battery time sucks...
Its never under 10% and spikey as hell.
[doublepost=1477916801][/doublepost]Since I started This testing now my phone has used between 15-20% of the battery....
I have a 5s here with 29% battery wear that only drains around 3% over night compared with the 12-15% my iPhone 7 drains, ..that is averaging 11- 15% CPU usage off charger here on the same iOS 10.1. It also uses more memory with all apps closed ..just over 500mb RAM compared with just 370 currently on the 7. Seems hard to find a cause of this standby drain problem. Let us know if you find a rouge process! Cheers
I don't believe in turning off any features of a smart phone.
So with everything on and all allowed over cellular I had perfect battery on my plus.
The first 3 days I was hitting 8hrs of usage and 20% warning after safari and Apple Music streaming
All of a sudden it's gone downhill
Now I barely hit 4.5hrs without 15hrs of standby.
The strange thing is my usage hours are precise and it's not similar to my standby time like some here
I remember I use to leave my house and surf the net and listen to Apple Music on the way to work and 30min later it would drop to 99 or 98%
Now I'm down to 90%
My fiancé on the other hand has the most amazing battery life I've seen
I set up her phone so every setting is the same apart from how she uses her phone of course
She returns from work and it shows 70%. Usage 5hrs 30min and standby 20hrs. Amazing

Check under memory now ..how much is being used with all apps closed? Might take a few mins to settle after a reboot as well
[doublepost=1477917425][/doublepost]
I have the same problem with nothing showing unusual under usage .. Usage doesnt increase with the standby drain on mine either so no clues there unfortunately
I have the same thing. Kinda funny. Girlfriend comes home with 88 percent consistently, 1,5 hours os usage (which adds up when you look at her Screen on Time). And then I get home with 30 percent left and 7 hours of usage on the counter without using the phone for even an hour. Eh. I'll try and get more info when I have the time on memory and such.
There is definitely something weird maybe the firmware. I bet apple says the battery is ok too
From my personal experience you can only solve the battery draining by deactivating all system services, deactivating background activity, activating low-power mode, activating airplane mode and also deactivating WiFi directly after you charged the phone to 100%. This works perfectly for me. This at least takes care of all hardware related activity that could happen.
Also, if your battery draining during daily use feels too much, download "Sysinfo Lite" from the iOS app store, do the above and look on whether your phone has constant CPU usage >20%. If it does, something is wrong with your backup / iOS installation and there's some background activity like services or something else that constantly sucks on your battery life in an endless loop.
If it does this, then you need to do a full restore to another iPhone, which was setup as new, backup that iPhone again and restore this new backup to the current iPhone. This way I resolved another iOS battery draining problem which also affected my 6s (since it's the same backup). Now, after doing this, the 7 is perfect.

Awesome. I just love it when people show battery stats where it clearly says that the phone has been plugged in, rendering them absolutely meaningless.
Oddly, my battery is pretty good except for something streaming related. I can watch videos on my iPhone 6 for about 8-9 on safari, but the iPhone 7 will heat up time to time and hold up somewhat less. Anyone else notice this?
