how is your battery life on ios 9.3?

[perfect_]

Same here. Looks like cpu doesnt go deep sleep mode or something. Mine battery draining every hour 1 percent. (Background refresh is off) This is not normal. It started with iOS 9.3.1

Yes and yes! I checked my battery logs. Definitely my cpu doesnt go deep sleep mode. Awake time is huge.

Can you please elaborate on the deep sleep mode and how you are monitoring it?

Simple. Some apps using cpu for whatever reason in deep sleep mode. We cant monitoring it. But we can check our battery logs and we have experience's from old iOS versions. We know the truth.

I really know what mean this semptoms. I used Android too much time. It so sad for me. I didn't never expect it on iOS. So here we are.

Im waiting full charge. I have to try dfu mode.

Are you seriously complaining about a drain of 1% per hour when not using the phone? Do you expect your phone to last for months when on standby?

If you are so obsessed with your battery life, you should turn off your phone when you know you are not using it for a long period.

Calm down Apple defender. We are not obsessed. We just can analyze somethings deeply. If you cant, you dont need to attack. Just remove ur black glasses.

Is that your "deep analysis"? Seriously, "we know the truth"? You are so funny.

Allright. Lets see your deep analysis. By the way its not just me. Look at the thread messages. I have a problem with battery draining and i can prove it. Stop talking nonsense.

You still didn't explain what "deep sleep mode" is. What exactly happens when the CPU enters "deep sleep mode"?

The only real way to debug battery drain is to use Instruments function in XCode on a Mac.

You can literally debug your phone in real time, seeing exactly what processes/services/daemons are going crazy in the background.

The worst offender I have seen is the mstreamd daemon related to the Photos app, and more specifically Photo Stream. There is times where this can just go crazy, even with all of the Photo Sharing/iCloud features disabled for Photos - the mstreamd service just endlessly starts, stops, and restarts forever.


This has been happening since iOS7, and has basically never been fixed (Apple should just put something in that basically kills mstreamd if you have Photo sharing disabled....)

So, first off, for iOS, 1% per hour while idle IS a lot of drain. Personally, I'm seeing more than that even after a full restore and setup as new phone. Phone was fine on and before 9.2.1. My problems started with 9.3 and continue on 9.3.1.

EDIT: To add, my "Usage" time is always about 50% of my "Standby" time now even if I do a fresh restart at 100% and then don't touch the phone for several hours.

 

[cableguy84]

On 9.2.1 i was getting about 3% drain overnight . On 9.3.1 im getting about 7% drain overnight, pretty big increase i would say

That looks like a problem to me. Even after some usage of my phone, the usage is less than 10% of Standby. You have a rogue app.

 

[Bladery]

Clearly according to CDM you are in the minority hence no such issue exists

What is CDM?
Is this post sarcasm? Not my native language

Then I have a rogue Apple app that doesn't report on the battery page because the problem persist even freshly after a restore as new phone. No apps added, nothing even setup other than what it makes you setup to get the phone running (iCloud). When I check the battery page after leaving the phone sit for several hours after a reboot, no apps are listed on the battery page.

This problem has existed on my 6s and my iPad Mini since the day I installed the OTA 9.3 and into 9.3.1 where I then started trying to fix the iPhone first by resetting all settings...then a restore with backup...and finally a fresh setup as a new phone with nothing added.

Problem remains.

It's obvious not everyone is having this problem...but something is triggering it and hell if I can figure out what it is.

No SIM installed? Is that right? I wonder what that would cause.

Hoping Apple addresses this

It makes no difference. I recently pulled the SIM because I didn't like having to take an external battery pack with me on long days out from the house. Put my SIM in an old phone until Apple fixes this.

I couldn't even go through half the thread because of how dumb these responses are.

Why do you immediately assume the battery is bad due to the update without waiting for the phone to do its thing for 1-2 days, restoring, or by checking your settings?

I've never encountered any significant issues with iOS in terms of battery life since 4.3.3, the first version of iOS I used. And, additionally, most can be resolved by checking/restoring your settings or by doing a restore. It is rarely iOS itself.

If you're encountering battery life issues, restore or check your settings. It's not the update, it's your settings and data.

So, you don't read much, do you? I have gone as far as testing for the last 2 days a fresh 9.3.1 install, setup as new phone, with no apps added and the only things configured are the things the initial setup makes you configure, like iCloud.

What I'm tired of? People who think because they don't experience something, that everyone else who does is obviously wrong and then treats those people like their idiots for having the problem.

Kind of like people who think that since they have a problem, everyone else does?

Point out to me where I've said that. lol

Is draining faster on my new 6s and now I am using it about 15 minutes and Batter Usage still shows: Battery information will be available after using iPhone for a few minutes.

What is "a few minutes" for Apple, please?? Are they playing with users??

Nothing new. I have been reporting that for a few releases now. Use the feedback site to report it: http://www.apple.com/feedback/iphone.html

Im having this same problem too. I've even restarted the phone after a full recharge and with no apps running and usage time will always be 20 minutes out of very hour standby. Therefore the usage statistic is not in the least accurate as to how long I've been using the phone. I have noticed this since ios8. I used to think it was the ⌚️ constantly communicating with the but I have discounted this (leaving the ⌚️ off and Bluetooth off too). I have background refresh off and all other settings disabled too. The only time usage doesn't seem to clock up is when I place the in ✈️mode. Perhaps it's the looking for a signal from a cell tower. Nothing else seems to make sense. Just my thoughts. Would love to have a solution to this.

My iPad mini battery is not lasting as long as it used to. Sitting on my nightstand, it used to last a month or more, and now it's barely a week!

I recorded an 168hrs standby time before its battery was dead. Just a week. Oh, on iPad mini 1st gen.
iOS 9.2.1.
