Settings > Calendar > Default alert times > time to leave
I've never had this option on, so I would be doubtful that turning it off will make much difference to the battery drain issue. Maybe I'm wrong.

Here is some info for you:Hello,
Thanks that you asked for it because I found network is never used so can be disabled. Yes these are my only turned on settings in system location services :
* find my iPhone
* compass calibration (it seems to help when you need proper gps signal by doing something ) so I turned it on again.
About "time to leave" someone mentioned that under calendar settings you find out Default alert times (or something like that ) and inside this submenu is a setting called "time to leave ". By default turned on... just a guess but why leave it on if you don't need it?
I am really looking for a description what does every setting in location services do.
What is WiFi networks and how it works and so on. Found only articles about saving battery by disabling some of them. Last places drain battery for sure.
Does every time compass calibration work like on 6s - it's "working" even when screen is turned off ? Each time I had location icon for system settings enabled this icon was in lock screen after I picked up phone.
Widgets I have are: what's next and stock weather widget which should not use gps anymore...
Finally got my 7 on Monday. Installed b3 yesterday on both the 6s and new 7, then restored my 6s setup to the 7 via iTunes.
On iOS 10GM, and any of the betas thus far, I've only been able to achieve maybe 3-4 hours of usage max. I don't even do much on my phone, and my settings are very well tuned to have any battery drain options turned off. Background refresh off, location services only when app is in use, system services only has find my iPhone on, auto brightness on, wifi/bt off, ringer on silent so no vibrations...etc etc.
Spent a full day with the 7 today. At 45% with 5 hours usage, and 12 hours standby. Night and day difference thus far. Amazing.
FWIW, these are the exact same usage stats I was seeing on iOS 9 with my 6s. Not to be that guy...but come on.
Technically some of this isn't actually correct and is redundant or out of order.Ok chaps, on the apple discussion board this method seems to fix the battery drain issue for some users..
* Be on 10.0.1 or below (downgrade if necessary)
* Reset All Settings AND Reset Network Settings (in Settings-General-Reset)
* Backup in iTunes (If prompted to Download and Update, select "Download" (only) so 10.0.2 ipsw update is available but not installed (do not proceed with update)
* After iOS download completes (mouse-over spinning circle in top-right of iTunes to see download status) re-Connect USB and in iTunes select "Restore iPhone" (As long as the ipsw downloaded, you will be Updated to 10.0.2 during the Restore)..
* Near the end of the Restore & Update process, hopefully you will be prompted to "Install Carrier Update" (This seems to help)
* Probably a good idea to use iPhone for 24-48hrs on 10.02 to observe battery life before changing settings significantly..
Might try this myself if the next OTA update doesn't fix the excessive standby drain on mine
Cheers
Can I ask .. did you install the b3 on your 6s OTA?
I see you've turned everything off almost on it but your battery still sucks. If you've tested the battery capacity with an app like battery life etc and it's still decent then there's a problem with the OS install.
I've compared 2 iPhone 7's here, both set up almost the same with similar stuff switched off in settings and back ground app refresh, location services etc setup the same. Both iPhones battery's drop at a similar rate whilst actually doing something on the phones but the one drops around 15% battery if left alone for 8 hours on standby and the other drops around just 4% in the same time!
Only difference is the one that suffers standby drain was updated from 10.0.1 to 10.0.2 OTA and the other was set up as fresh install on iTunes to 10.0.2.
It seems clear to me that in most cases where the phones are suffering abnormal standby drain on iOS 10 it's something corrupted or gone wrong with the install of the OS on the phones and not a setting that needs changing.
I've posted this before but I'll post it again, ..on the apple discussion boards this exact procedure seems to have fixed the standby battery drain problem for some users

* Reset All Settings AND Reset Network Settings (in Settings-General-Reset)

* After iOS download completes (mouse-over spinning circle in top-right of iTunes to see download status) re-Connect USB and in iTunes select "Restore iPhone" (As long as the ipsw downloaded, you will be Updated to 10.0.2 during the Restore)..
* Near the end of the Restore & Update process, hopefully you will be prompted to "Install Carrier Update" (This seems to help)

Even with a clean install of any iOS 10 build, including the GM - I was only ever able to get 3-4hours of actual usage. Rolling back to iOS 9, and I was able to achieve the same battery life I am now once again starting to see here on the new 7. I've never been one to buy into that whole 'planned obsolescence' banter...but idk now...it is very curious, to say the least.
EDIT: yes, to answer your question I have tried installing directly from iTunes rather than OTA...as well doing clean installs.
both my ipad 12.9 and iphone 6s are now experiencing pretty bad battery drain (not terrible but pretty noticeable now). Initially after installing 10.0.2 when it was available, things seemed fine. now in the last couple of days:
on the ipad -- i used to be able to browse with chrome/safari for a good hour so before i see a percentage drop in battery. now after 8-10 minutes of browsing, it drops a percent. that's a significant difference. no problems with overnight draining though; no drop in battery percentage after 5 hours of sleep. which leads me to the iphone...
on the iphone -- this 6S is about a year old. i usually don't have a problem with overnight battery drain (1-2% maybe?). but in the last couple of days i've lost 7-9% overnight (5 hours of sleep). then lost another 6% on the drive to work, which was about 30 minutes (bluetooth was on as it usually is but i made sure not to use it i.e. didn't switch to pandora.
my usage habits had not changed so something is up
just quoting myself above for comparison (the above was behavior i was seeing yesterday morning and the night before that).
i've continued digging through settings and think i may have got something that worked*. in settings --> calendar, there's a few more settings that may be doing stuff in the background that may not register in battery use or location services but could possibly be doing something in theory:
Settings --> Calendar
-Default Alert Times - disabled "Time to leave" (reading it's description says it may involve location so i killed it)
-Location Suggestions - disabled it
-Events found in Apps - disabled it
Battery percentage was at 75% before the settings change. I've had it like that for about 2.5/3 hours now. in that time i've used safari a little bit (including some testing with voiceover), instagram (viewing feed, including videos), appshopper, and took a few pics. battery percentage is still 75%!
*at least on my iphone 6S. i'll check my ipad tonight and report back. if you try it, please give feedback if it works for you.
Quoting myself again in case anyone is following my little journey...
I think i fixed my overnight battery drain on the iphone 6s. Turns out, when going through settings to try to kill some things one by one, i completely forgot to check on Siri. I'm a "Hey Siri" user (not often but i have it on) and just completely slipped my mind to kill that when trying to diagnose this overnight battery drain issue.
well, last night i finally remembered and disabled "Hey Siri" and happy to report, though cautiously optimistic, that i had zero overnight battery drain after 6 hours (48% at 11pm, 48% at 5am). in previous report above, i had 7-9% drain overnight; ~5 hours of sleep.
now i just have to remember to enable / disable "Hey Siri" accordingly.
Hope this helps others.
bug in 10.0.2? i dunno as it didn't seem to be a problem with 9.3.5. trying to narrow down / rule things out.How would having Hey Siri on cause a battery drain?.

i'm going to keep track of 'hey siri' on/off overnight tests for the rest of the week. i'll update with results accordingly
Don't laugh: iPhone 5. 10.0.2
After seeing an article about damaging our batteries by over-charging overnight, I've been trying not to. Several nights recently I've gone to bed with 100% battery, left unplugged. When I wake up, I've got 80%-85% battery remaining.
WTF? I have most of my non-essential background refresh apps off (because iPhone 5). Mail has been failing to push new messages through. Yes I know I can put it in airplane mode and this won't happen, but I would really like to know what my phone is doing to burn 20% of its battery while I sleep.
you don't think it might be a problem with the mail app? if it has problem pushing messages through, it might also be having problems sending them out. check your outbox; if there's mail stuck there, it could be constantly trying to get those out and possibly be the cause of the drain.Don't laugh: iPhone 5. 10.0.2

I installed 10.1 Beta 3 and so far so good. Battery life does indeed appear to be good again!Battery life in 10.1 Beta 3 is really good...I went the whole day at work and I am only at 70% on my 7Plus.
It is first discharging after downgrade SE to 9.3.5 so it's indexing, getting cache and so on... But in my opinion it's working better than 10.0.2 :
*no problems with battery drain (only 2% by night )
*back to old messages without childish view
*slide to unlock will help in winter and unlocking by fingerprint are faster than on newest one
*battery last longer and there are no dropping % I had last days (had full discharge and only 87 cycles )
*wifi speeds are better (120 vs 150 on 9.3.5 )
*mail app is working as it should - no translation glitches...
*in reduce motion it's faster
Overall 9.3.5 looks like old business iPhone not entertainment device we have on iOS 10.
Glad to downgrade and have fun being beta tester on GM ones
