iOS 8 Users Seeing Issues With Battery Drain, Slow Wi-Fi

I think to do performance testing you simply have to stress the test into extreme conditions and you get it done. The difficult part is having optimized solutions to pass testing. If the test criteria are overlooking behind the scene background processes that :apple: and all the other "partners" are data mining the testing will always be a crippled one.

Stress testing is only a portion of performance. I'm pretty sure Apple performs numerous soak tests in high stress situations.

Performance testing should compare the new product versus the old for every day use. For example, I'm sure Apple has extensive benchmarks for boot time, charge time, etc from each of their devices to compare to. It's difficult, though. True performance testing is probably impossible to beta test on iPhone as there are countless variables in terms of wi-fi connection providers, network availability, and usage bases.
 
Seeing wifi connection issues with my Touch. Usually has been by next morning it doesn't connect well, so I've turning wifi off and then back on to get good connection again. Will try the suggestion on first page.
 
I am actually getting better battery performance with IOS 8.0. I always backup prior to the upgrade and then do a FRESH install + Restore from iCloud. I have seen some hesitations with the screen failing to rotate when it should (but I think I can live with that until 8.01).
 
I've seen rubbish WiFi on my iPad Mini Retina with iOS7, my Mums iPad 3 was WAY WAY WAY better, reading around I saw that this was down to Apple changing to MIMO for the Retina Mini and was another 'known issue', but with iOS8 it seems to have nearly resolved it.

It certainly makes me think Apple doesn't test a thing they make anymore, just shoves it out the door then fixes it later with an OS patch. Very sloppy and cheap manufacturing I think.
 
Been using my new iPhone 6 around the clock. Overall the battery life is better than my 2 year old 5, but comparable to when my iPhone 5 was new.

Wifi speeds seem the same for all pages. Haven't noticed anything being sluggish though we have a fast connection here as well.

Antenna gate was something everyone could replicate. This is something where people will always say something is slower than there last version or uses battery faster since of course they are using the new device 100x more than their previous old device even though of course they are going to say in their comments they are using it the exact same amount.
 
I find that disabling all the mail options in mail, calendar and contacts profiles and then re-enabling them eliminates the battery drain -- re-syncing your mail (especially those people using Exchange).
 
Just fixed wifi issues with Network reset, battery life has been really solid. Only drained 15% during the work day today with some light usage throughout the day.

I recommend looking up a ios 7 battery life guide and applying it to your new phone. Things like background updates and push email will certainly eat up battery. Makes sure to manually Fetch all boxes set through your settings>email page if your job doesn't demand you to have instant email notifications. This most definitely applies to all people who have email access at their office computers.

Turn Facebook push notifications off. You know who you are. You don't need to be involved in your personal social media while at work.
 
I see a lot of memory leakage. I am using battery doctor to keep cleaning things up. This seems to work if I run the memory clean every hour or so I have had all day battery since getting my phone on Friday. If I did not use this utility it would be ugly.

It's the apps, people. Whenever a new version of the OS comes out there are apps that are not optimized for it, and those apps cause things like excessive battery drain, hang ups, memory leaks, etc.

It will all settle down shortly.

But if something is wrong, it all has to be Apple's fault! :rolleyes:

Everytime people have issues, other people on this site dismiss them as if Apple products are not prone to legitimate bugs.

Every time someone doesn't experience widely reported issues, other people on this site dismiss them as either clueless, or even sometimes liars. It goes both ways, and the truth is in the middle.

What iOS update doesn't see battery drains on the older devises. And wifi issues for that matter. Happens every time for some folks. LOL

Yup....

1) Apple cannot test every WiFi router, so invariably some have issues. I never experience these because I have Apple WiFi routers (which they do test)

2) App updates come fast and furious just after an iOS upgrade and your iPhone will drain its battery all day long doing automatic updates to new versions of apps.

After a few days of app updates, my battery consumption has returned to normal. Nothing to see here.... move along.
 
APPs Freezing with Network Access

I have several apps that freeze when trying to connect to a server.

I can usually restart the APP and get it to work.

Im on a 5s with iOS8 as well and have seen my battery getting low faster than with iOS7.

Ive also had APPs not exiting properly.

All small issues that do not prevent me from using the device, just a little annoying until it's corrected.

In order to improve the battery life for my iPhone 5 I disable Background App refresh for all Apps, i used to have some apps working fine previously with iOS 7.
Also deleted Facebook App, what a piece of crap. Now accessing it via the web.

All location services disable too.

Still not as good as with iOS 7.

I used to work all day and when coming back home need to charge in the car.
Today I had to plug in after lunch...

And which apps are using up most of the battery charge?

Some users reportedly had luck fixing the problem by disabling Wi-Fi Networking under Privacy --> Location Services --> System Services.

What does this do? Disable A-GPS where Wi-Fi is used to assist GPS?
 
Beta testing

I've been testing iOS 8 in beta from the first release and have not had any issues with WiFi or battery. But that, is not to say they do not exsist.

The first public release we always hear these issues, some are legit, some are not. The first real world test is just that, when the world gets the update, the the stress test begins.....:cool:

Give it a little time and an update will be here soon enough.:apple:
 
iOS 8 is nothing but crap.
Just called a colleague and got vm. He sent auto text back saying busy.
The call would not disconnect and intead made me hard reboot the phone.

I have had this 6 since Friday and have hard rebooted 4 times do to PHONE issues like this.
Pathetic.
 
No issues so far either.

Battery life is definitely better, after the first work day with the 6 it's down to 61%, my 5 was usually at 40ish%.
 
...I'm good waiting a month or two while people beta test the new iPhone and iOS for me.

I'm sure sure production issues and bugs will be ironed out quickly enough.
 
There is undoubtedly a problem with Wi-Fi on iOS 8. These results are from my iPhone 6 on Verizon. Note the first three tests I did were on Wi-Fi, with the final test on LTE. After the very first test I disabled the WiFi Networking option the original post referenced l, but to not effect.

Side note: Has anyone else noticed the clock bar at the top having major formatting issues in most apps? From my understanding, this doesn't entirely have everything to do with the app itself. I did not notice this in the developer beta.

I've been running all day, and I'm at 86% on my iPhone 6.

Im at 52% after a few phone calls, surfing web, etc. not too bad. But then i don't leave wireless on, location services turned off. I even checked FB, which really sucks power.

I've said this before and I will say this every year with a new major update: I've never had any major problems or bugs with new releases. Why? I always, always RESTORE AND SET UP AS NEW. new OS? Let's make sure your data was created in that environment to work. Most specifically with battery drain issues.

Set up my iPhone 6 as new and synced all my stuff over iTunes/iCloud and downloaded my apps manually, I've been seeing about 2 day battery.

So, do you backup, then restore from backup? Or just reset to factory settings, then do everything manually? Sorry for the basic question - not very technical.
