I can see the logic in keeping the phone on the launch iOS version it came with but Still I'm quite happy with the way my 5s performs on the iOS 10.2 beta and it came with iOS 7 installed originally
Got a tip for us?
Let us know

Same problem with my launch iPhone 6. I'm pretty sure it started with iOS 10.1.1, phone shuts down around 15% battery.
Ouch, not normal at all, you certainly need to get in touch with Apple. What are your settings? (Background app refresh, signal strength at home etc.)
Yeah definitely not. Going to book one asap, background off, full bars and this has never happened until last night
Good luck, let us know what happened. Last thought, did you install any new apps recently? Especially ones using location, though even that shouldn't eat up so much battery.
That's horrendous standby drain fella.. I sent my 7 off to apple repair last Friday due to 15% standby drain over night (that nothing will fix).. it's on it's way back to me tomorro.. so hopefully they've either fixed the problem or replaced it.
The first thing I do when my battery life goes haywire is do a clean reset, set it up as a new iPhone, charge it up to full and use it like normal. Check SoT after 20% drain and estimate overall battery usage over the entire battery. If I've used 20% of my battery with anything less than an hour and a half of SoT, then I'd head up to an Apple store and get it checked out.
It could simply be an app keeping location services live all the time. Check those settings, see if it looks like something is keeping it pegged.

People who think iOS 10 is the sole factor of bad battery life do not understand how these devices work, and everything that factors into battery life. I've seen people complain about their battery life, and I'll ask them how long it has been since they have reset their device (done a factory reset), and they'll look at me like I'm stupid. I'll further explain what I mean, and they'll tell me they've never done that in the 3 years they've owned the device.
*flips over table* Really? Would you use your computer for 3 years without having any cleanups or maintenance done on it? Would you drive your car for 3 years without changing the oil? Why do people think they can use technology for years on end without doing any kind of maintenance to ensure these devices operate properly?
Well that's potentially the problem right there...
My friends used to make fun of me because I used to format my hard drive on my computer and reinstall Windows pretty regularly (every 3-5 months), and I do the same thing with my phone. It get a clean reset every 3 months or so. However, there is one thing I can say; my devices always perform just like they did out of the box.
These devices are like mini computers. There are some settings that get changed under the hood that cause things to go haywire where the only way to fix it is a nice clean reset and a fresh install. Why? It just happens. Devices will go rogue where they won't connect to Wi-Fi for example (we have an Apple TV doing that across the street). The Wi-Fi is fine, we all use it on a daily basis. The device simply needs to be wiped and set back up. This device probably hasn't been wiped since they got the thing, and there's no telling how long that has been.
So before you blame an "update" to your OS for your poor battery life, you should at least do a factory reset and set your device up as a new device (don't restore from a backup, that's going to bring in any settings back that may be contributing), and see how it performs then.
If it's still performing poorly then there is something going on deeper than just the OS. I've been running iOS for a while on varying generations of iDevices. iPhone 5S, iPhone 6 Plus (when I had it) and now an iPhone 7 Plus, and I have had nothing short of stellar battery life on all three devices.
And your IT department is right. You shouldn't be running on an old version of iOS (or any operating system for that matter). We require all company-issued devices to immediately be updated when an OS update is released, no exceptions, unless there are known issues with that revision that break things and cause issues.

Depends on the apps used.
Again; if I turn off Siri I get 2 percent drain during the night, with Siri turned on (and he siri off) it drains 6 to 12
But I've seen most people get 8-10 hours of usage, surely turning off siri wouldn't hinder the performance that much?
Paired my watch again after consistently making it through a day with 70 percent left. Within 3 hours I dropped 20 percent. God damnit what is up with IOS 10? It is NOT a hardware problem since I don't have drain in airplane mode, I Don't use my phone heavily because I work, but it still shows HOURS of usage I didn't engage in. Just because I have watch Paired.
I miss my iPhone 6, that thing would last LONGER with the watch paired.

Well, as others in the thread have pointed out, even older devices are seeing this, including my 6.
This happened last year as well when 9.2 came out: my phone's battery meter/usage would be all over the place. Seeing similar with 10: quick drops in available power, occasional drops from (say) 40% to single digits, then back to 40% as soon as phone plugged into charger. Once 9.2.1 was released, battery life was normal again.
Why the software behind battery usage/reporting keeps breaking between releases seems odd: you'd figure that that is a core component and not be changing frequently or at all.
Don't know if this was reported earlier (too many posts/pages to go through), but, had an interesting thing happen.
Ala my earlier post, had phone go from 43% to 1% instantly. Shut down and gave the "plug it in" icon. After a couple of minutes sitting (out of the house and no charger close), rebooted with no issue and back to 43%.
As I'm guessing from last year, serious software issue that keeps getting re-introduced on new releases. Why some releases amd others not... odd.
