Yeah, but it takes a while for it to drop from 100% to 99% even while using it(30-45 minutes of usage) so it's not surprise that it doesn't drop below 100% overnight!

iPhone 7+ Overnight & Standby battery drain

Like the above poster said there IS battery drain, it is just that you battery gauge stays on 100% much longer than it should. There are some days when I might be hours into my work day and my battery still indicate 100%.
the iOS 10.0.2 software is really flawed and has a great amount of work that needs to be done to make it stable and reliable, from springboard refreshes to battery drain, its all just a mess on the iPhone 7 at the moment, hope apple releases and update soon
Changed it at the genius bar on Sunday. Night and day difference. Definitely a battery fault in the last one.
Was at 99% at bedtime last night, woke up the plus was at 87%, I think it's the lockscreen getting wake locks, I've updated to 10.03, hope 10.1 fixes this standby problem, never had this problem on the 6 or 6s, only lost 1 maybe 2%, the thing as well I'm getting pissed with is ios10 is supposed to be finished software, all these betas to developers and public is only doing apple's work for them, this was the best thing about Apple, software!
[doublepost=1476919525][/doublepost]Also as well has anyone that's updated to 10.1 beta noticed the standby time issue fixed?

Yes!
I suffered from excessive standby drain (2% per hour at least) since 10.0.2 and .3 was no better.
There was definitely something in the background causing this because the battery life was excellent while actually using my phone (screen on), but I couldn't find any app or back ground activity that was the cause.
I recommend the beta

Ya I'm happy with the battery life using the phone too, our complaint and praise are the same, Well that's good to know that there is an improvement in 10.1 and maybe even more in the final software, I'm not going to install betas, had bad experience of them a while back where i got glitches in the ui and they carried over to the final software and i couldn't get rid of them, was really annoying!
Hopefully you'll get the final release version soon and it will fix your standby drain too
Just pitching in because the battery drain on my iPhone 7 makes me pull my hair out. You guys complaining about losing 2% battery per hour with no use makes me smile, because hear this: I'm losing 1% per 6 minutes even with the phone turned off! Not just locked, actually off. I'll go to sleep with 80%, turn it off and wake up without being able to turn it back on again.
This started after I updated to 10.0.2 on the evening it was released.
I got in touch with @AppleSupport on Twitter, they ran the hardware test remotely, which apparently successfully completed, which made them say it's not a hardware issue. Obviously I checked the battery usage and there isn't any particular battery-hungry app: it's just proportional to whatever apps I use. Apple Support suggested I restore the phone to factory settings but I don't have a good enough connection to restore my 110gb of data and 380 apps.
I can't back it up on iTunes because I keep getting the "couldn't complete the backup because the iPhone was disconnected" error message, which is another story that I have yet to solve despite hours searching for solutions here and elsewhere.
I've been an early preacher and fervent promoter of Apple products for as long as I can remember, but I'm getting really sick and tired of Apple's increasingly disappointing software and hardware.

Ok well 1% every 6 minutes sucks for sure
.. I'm one of the unlucky ones (but luckier then yourself) who is getting the 2% standby drain every hour.Ok it doesn't sound so bad when your getting much more severe battery drain but it's still nowhere near how the phone should perform. I have an iPhone 5s here also running 10.1 which is set up exactly the same as my iPhone 7 with the same apps installed .. this iPhone 5s has 29% battery wear according to the battery life app but it only loses around 1% every 3 hours on standby! That's how ios 10.1 should be if it's all working correctly!
I have a problem with my iPhone 7 you have a serious problem with yours.
I intend to try a DFU restore when I get Some free time .. I recommend you do the same when you can get connected to a decent internet connection
Update: installed 10.1 yesterday evening and kept the phone charged all night. Left home this morning and by the time I got to work (1 hour) I'd lost 18%. And that's not even through intense use, merely sending a few text messages, turning the screen on a few
Times to check the time, and a combined 10 minutes on Safari.
The best is how they test your hardware and say that everything is fine on this front, but what if the test itself is flawed?
At any rate, I'm really losing patience.

Apple may replace it but they'll most likely want to try a DFU restore first.
Guys it's the compass calibration in system services that is constantly on when the phone is in standby, SWITCH Off , i have found that if you go to system services and switch on, show status bar icon, and have compass calibration switched on, then go to homescreen and put screen off, next wake phone without going to homescreen you will see that the GPS icon is already on, meaning it is on all the time in standby, try what i have said and the GPS icon will no longer be on in the status bar when you wake the phone, I have tried this over and over and it seems to be that with compass calibration switched on the GPS icon is constantly on in standby, it's not that the GPS icon comes on when you wake the phone it's already on so it's on all the time, so switch off and see for yourself!
Had already tried, but just tried again to be sure. Every single location service is off and I've already lost 10% in 25 minutes.
I wonder if there's a bad batch of A10 chips that don't switch to the low powered cores effectively how they should?
The iOS battery meter does not start moving until the battery itself is at 95%. After that it is a linear drop. 100% Readout = 96-100%. 99% Readout = 95%. 50% Readout = 47.5% and 1% Readout = 1% battery life remaining.
For whatever reason, all Apple products are like this. Macs, iPads, iPods and even Apple Watch. Now with that being said, when you are charging the device and it reaches 100%, its really only 95%. That is why I use Coconut battery on my mac quite often to see if my device is truly fully charged. It typically takes 35-40 minutes to trickle charge from 95% to truly 100%.
Well you've obviously got excessive battery drain, that's not normal, I'm talking about people that were getting 10-12% battery drain overnight in standby, with my findings of the GPS icon constantly on in standby with compass calibration and probably routing and traffic enabled, this surely has been contributing to battery drain, I mean every time in my testing that i woke the phone without going into homescreen the GPS icon was on already, i think this is why you see in a lot of people's battery usage screenshots that home and lockscreen using alot of battery, also of note the performance and battery life has improved hugely since the 10.1 update!

That is why I use a portable charger with a light meter. Whenever the battery indicators are lit I know the phone is still being charged. However, when the lights go out on the charger and the charger is switched off I then know the phone is charged
I know cellular signal strength affects the battery a little, but to what degree is uncertain.
Could your phone be in a very weak signal spot where you leave it sleep overnight?

Yes. I'm getting 12+ hours of screen on time and 20+ hours of standby.
Currently at 3hr usage/13hr standby and at 80% remaining.
