ios 8.3 battery life

This special characteristic of Unix based system is that system will use as many resources it can access as possible. This is quite different from Windows.

But bigger memory brings the better performance, that is true, though.

In fact, this "merge" just help you to set your phone with a series of settings you are familiar from your previous device. You don't need to change any settings on your phone and you can change no setting on iCloud.

iCloud is just a service using Internet to operate. And I guess the antenna or Wifi component on your phone might works improperly. Consider asking for a replacement of your phone. In fact, since more and more phones become thinner, more compact, it greatly increase the difficulties of assembling them, or repair them with conventional tools. So I can expect there would be more phone with such issues.

My wife and I both have the iphone 4s. Since upgrading to iOS 8.3, we've experienced significant reductions in both battery life and speed. Apple, historically dedicated to excellence and customer delight, seems to be losing its way. Sad...

Much worse for both speed and battery life!

Same here. Till yesterday I have had a beautiful well going iPhone5s. Then I've made a horrible mistake and upgrade it to iOS8.3. Today I have overslept for work because my battery run out during the night. From 47% till 0% in standby mode during the night!?!? Now in 2 hours from 45% battery came to 23%! Without using a phone, all applications are switched off. Disaster!!!

WOW! From all these comments it sounds like iOS 8.3 is really the opposite of what Apple intended it to be, hopefully the 8.4 Beta will listen to consumers and fix the bugs before releasing it to the public

On an iPhone 5, disabling as many of the new iOS8 features as possible may alleviate some of the energy management/processing problems – but it’s is not a general solution and probably not the only cause of unacceptably high battery drainage.

It's becoming clear that the HW cannot cope with many of these new features in real time as well as deliver useful functionality on par with earlier iOS versions (which were available during the warranted life span of this product).

You can try to ask for help from Genius Bar. They at least, can submit your issue to Apple.

And, hope Apple can find a solution.

I think it's a good idea for everyone if they have time to make an appointment with the Genius Bar. The more Apple is made aware that there is a problem, the more willing they will be to try to fix it. If they don't know it's a problem, they can't fix it. I have an appointment on Saturday. I'm hoping they can help and if not, at least they know one more person is losing faith in their product.

The worst battery status came with the iOS 8.3

Woah, really shocked at how many problems came with this iOS update. What devices are you experiencing the issues on?

For me it's mine and my husbands iPhone 5S's. I have not updated my ipad mini yet (thank goodness), and I am afraid to. Do you know if 8.4 is scheduled to come soon? We can only hope that Apple knows about this and is working on a fix in the next update.

How is your iPad mini performing without the update? i have a feeling we could see the update appear to us end of May, early Juune but please do not quote me on this. However, I doubt the update will be beneficial.. I really am not looking forward to iOS 9

It's performing just as before. I really haven't noticed any changes. Thanks for the info. I guess I'm an optimist because I feel Apple has to do something. We pay a lot of money for these devices. If a software update renders it less functional than before they need to fix what they damaged. They may not feel an impact right away, but they eventually will when people start jumping ship to other brands. I hold out hope for my appointment on Saturday....

its easy way to let your battey good

1 : charge it when its 20 or less than 20

2 : dont use it the whole time

3 : dont charge Every time charge it for 100 and let it on 100 and let it charge for 10 mins more when retchs the 100

4 : use original Charger (only)!

5 : dont charge like when it 100 and you played and its 90 and you charge it again this is gonna kill the battery
