how is your battery life on ios 9.3?

I can't tell if it's the Apple Watch with 9.3.1 or just 9.3.1 itself. Whatever it is it's terrible and actually starting to affect my ability to use this phone for a full day
well, I went thru every setting to find the drain. I then restarted and the battery seems to be normal (for me) again.
there was a few changes I made, even turned off night shade but I have no idea what was causing the drain.

Unfortunately, I have a feeling we are unlikely to see this patched until iOS 10 in the Fall, if at all. I haven't seen any reports of a 9.4 in development, and with a beta release in two months, it's likely Apple is now devoting all of their attention to iOS 10. Furthermore, I feel the only way Apple is likely to address the battery issue is if they receive negative press regarding it. Look how quick Apple fixed the URL bug with 9.3.1 after negative press hit. I haven't seen any press about a battery issue at all. In fact, I just read a headline referencing "the successful 9.3.1 update." If the press's headlines are glowing, and therefore consumer sentimate is that 9.3 is fantastic and no big issues exist, then Apple has very little incentive to fix this. For whatever reason, the issue doesn't seem to affect everyone, which makes this even less likely for Apple to fix it - either that, or most people just don't notice or care.
As for me, I'm very frustrated and angry. I just bought my 128gb 6s Plus in late February - specifically due to the battery life. I performed meticulous controlled testing on 9.2.1 and after 9.3 to determine battery drainage. I'm getting an average of 25% less standby life than before the update, and the battery drains twice as fast during use. To spend $1000 on a device, only to have it this badly "damaged" within a few weeks by Apple's own minor update is maddening. I'm also seeing my iPad Air drain about 50% faster during use than before the update. My iPhone 5 is also not lasting as long as on 9.2.1 either. So this is effecting a range of devices. I've never had an iOS update have such a negative effect on my devices as 9.3.

Still have battery woes but has been somewhat improved since disabling Siri. I checked my 6s's battery using Coconut Battery and it states the battery has 95.6% health with just 83 cycles since September. My retired iPhone 5 has 957 cycles with 94% health. So I'm a bit worried.
My ongoing comparison between 8.4.1 and 9.3/9.3.1 still shows no change. Battery life on my Mini 4 is also great.
So the battery is fine. What in the battery stats is consuming your battery and what percentage...?
Same here. From my battery stats on my 6S+, I lost 60% in 7 hours. It says my phone has been used 6 hours, but I've been using my iPhone 6 this afternoon so it hasn't been used at all (the page shows "Battery information will be available after using iPhone for a few minutes"). Incidentally I took my 6 off the charger at the same time and both have the same percentage even though I've been using the 6. Normally I'd be at 95% or so.
You guys are getting absolutely phenomenal battery life by my iPhone 6's standards.I mean the best my iPhone can muster is this lousy battery life
I tried using my AW without pairing with my iPhone but its a crippling expreince and when I do pair it my iPhone battery percentage once below 80% starts dropping by the minute.I havent dared to try playing a game on my iPhone while having it paired with my AW.I am sure my iPhone will be dead in 2 hours flat

Most: safari at 24%
Followed by iMessage at 22%
Social media apps (Instagram and Twitter at around 10% each)
Two iPhone 6 phones, identically configured - standby drain is easy, just compare the reported %s.
In-use battery life is obviously harder since in real life, as opposed to in a test setup, actual use varies, but the 9.3.1 iPhone 6 is performing consistently with its performance on 8.4.1, as far as general impressions go.
Since you posted this the percentage might have changed. What about the times? How long has it been running in the foreground and background?
I have background refresh off so none of these should have any background processes working.
you're right it's now changed.
now, in the last 24 hours, I spent 1.2 hours on safari on screen... corresponding to 20%
40 minutes on messages....corresponding to 10%
Instagram... 20 mins on screen, 3 minutes in the background (how??) - 10%.
Even with background app refresh off, the apps can still run processes in the background but only for a couple minutes after it's been sent to the background. I stress the word couple in the truest sense of the word. It could be a post that hadn't finished (even if it says it finished) or suspending the app after refreshing the feed. Those things take seconds to complete and over a period of 24 hrs can accumulate to 3 minutes. This seems to align with the fact that Instagram seems to be the third most battery-consuming app on your device.
What you want to pay attention to is the time you've spent on each app and the amount of battery consumed. For example, you said Safari consumed the most at 20% in the past 24hrs. You also said it was on the foreground for 1.2 hours~ 1 hour and 12 minutes.
Then factor in what the app was actually doing during that time. Safari can be used to constantly make various HTTP requests (jumping from link to link), load that data into the view whether it's text or images, play video and audio, and retain multiple tabs in memory. When you acknowledge that fact and you think about what you did in that hour and 12 mins, ask yourself if you were watching videos in safari, doing any image searches and loading pages with lots on content. Once you have that in mind, does that sound reasonable to have taken up 20% of your battery in that hour and 12 mins? If not, by what margin? If it's not by a whole lot than its safe to say that it's more likely reasonable than not. This is why battery life can be tricky to diagnose and be skewed by perception. If you want to find out the truth (and be certain about it!) then you'd have to constantly record and categorize by level of intensity what it is your doing in each app and for how long until the battery dies.
I'll tell you right now that the biggest drain on my battery is safari and I've spent an hour and 18 mins on it in the past 24 hours. It's consumed 36% of my battery and I'm seeing all day battery life on my device. I too have background app refresh off and have some apps with background activity recorded. A lot of my time in safari is spent watching videos and opening multiple tabs at once. So in my case, 36% makes sense. I hope this was useful.
Your screen shows the same problem mine does... that "Usage" nearly matches "Standby". Something is running and depleting the battery, even though the phone is not being used.

Hmm, that's a good point. I haven't turned on my watch since this started. Maybe I'll try that today and see if I can match you.
My usage is accurate in that screenshot. Now however it's 7 hrs instead of nearly 11.
I use my phone for work btw so 10-11 hours of constant usage (phone and music) is normal for me.

I agree. My 6S battery life was (prior to 9.3.1) phenomenal. Best of any iPhone I've ever owned.

I played around and finally got my "usage" time to stay down while I am sleeping:
Lol I'm glad. Like I mentioned my usage time although high is accurate. I conduct business from my iPhone and it streams music when I'm not on the phone.
Has anyone noticed any additional battery drainage recently regarding iCloud sync or iMessage? It seems like the battery drains excessively on my iDevices on standby when I'm doing something on another device involving iCloud, even though I have iCloud syncing (Notes, Cal, Safari, contacts, etc.) set to manual.
For example, my iPhone 6s Plus will drain approx. 2-3% overnight (8hrs) on LTE. Yet, I can go to my MacBook, edit a few notes, work with Safari (tabs & history sync with iCloud), and send a handful (3-4) of iMessages, and in a very short period of time (say 30min), the iPhone in standby will have dropped another 3-4% (more than over 8hrs). Furthermore, in that 30min, the "usage" meter goes up about 25min even though it's not being used! If I don't use iCloud or iMessages on my Mac, the iPhone won't drop at all (or just 1%) in that 30min period! Again, Notes and Safari shouldn't be syncing until I open the app. Everything is on manual. The only other variable is iMessage, and I have "Do Not Disturb" turned on so the screen isn't lighting up.
Sending and receiving only 3-4 iMessages from my Mac never used to cause such a considerable drain on the iPhone in standby sitting on a table. Sending iMessages from my Mac never used to make a considerable or noticeable battery difference to the iPhone in standby at all. This makes me wonder whether there is some bug regarding iCloud or iMessage. The interesting thing, I downgraded back to 9.2.1, and am experiencing the same drain I saw on 9.3, which makes me wonder if there may not be a recent server-side issue with iMessage/iCloud going on which affects both OS versions, causing excessive server pings/connections or time-outs causing the battery drain.
Trying to figure out if this might be a bigger issue. People who are noticing excessive phantom usage, are you perhaps using either iCloud or iMessage on another device (Mac, iPad), or are you getting many incoming iMessages, when you notice this phantom usage increasing? Anyone else notice anything like this?
