Have you noticed that nobody ever has problems any more – just “issues”?
If you have updated an iPhone or iPad to the latest version of the operating system (IOS 8), you may have noticed that it becomes alarmingly warm and that the battery life has shortened considerably.
This may not a problem at all. It may just be IOS cleaning up after itself following the update. It could also be caused by your apps automatically updating themselves following an operating system update. To check whether apps are automatically updating (and to change that setting if desired), go into Settings, iTunes and App Store, scroll down to Automatic Downloads, and check/change the Updates item. The other items in Automatic Downloads, by the way, enable/disable automatic downloads onto this device of any content that you have downloaded onto another of your IOS devices.
It could be that everything settles down after half an hour or so and that battery use returns to normal. If it remains very warm, it may help to re-boot the phone by depressing the power button (on top of the phone) and the Home button simultaneously until the screen goes blank and the Apple symbol re-appears.
If battery drain is still a problem after a re-boot, then have a look at whether apps are refreshing themselves un-necessarily when they are open but running in the background. To do this, go to Settings, then General, then Background App Refresh. I had a couple of dozen apps refreshing themselves in the background that didn’t need to. I’ve now reduced this to just podcast downloads, Google maps, and Bus Checker that are allowed to update their content while I’m not actually using them.
Another thing you can try (especially if you are concerned about privacy and having your location reported back to apps un-necessarily) is to turn off any location services that you don’t need. Go to Settings, Privacy, Location Services, and either turn off the app’s access to your location or turn it down so that it only accesses your location while you are actually using it. I was very miffed, by the way, to see that the London A-Z app insists on ALWAYS having access to your location when the app is loaded – even if it’s running in the background. Is my location being constantly tracked and reported on? I don’t know, but I try to remember to close the app when I’m not using it. This is a pity, because this app is one of my most important – travelling, as I do, to see computer support clients all over London.
You may have heard that the first release of IOS 8 caused some users problems in cutting the phone off from the telecomm provider. Quite a problem, and it serves to illustrate that no matter how carefully an operating system is tested before release, bugs are still probably present when the version is released for general use. So, if you do have any issues that crop up after a major update to the operating system, then keep checking for a few days that you are keeping up to date with the latest version as you may be experiencing a bug that has been fixed in the very latest version. To do this, just go to Settings, General, Software Update. You will then be advised whether you are up to date.
While on the subject of checking for the latest release of a new IOS version, there have been many reports that IOS 8 may run slowly on iPhone 4’s and on iPad 2’s. There are reports that this will be addressed in version 8.1.1. See the Ars Technica blog, for instance.
I’ve had my (nearly) new iPhone 5 for about ten days now and I must say that it’s nice to be using an iPhone again. My Sony Xperia (running Android) was a pretty good, mid-priced phone (except that T-mobile gave it to me for free AFTER I’d agreed to renew my contract – odd!), but it never really compared to the smoothness of an iPhone, and synching music to it via iTunes is just soooo much easier than manually copying files. I hope this doesn’t mean that I’m becoming an Apple Fanboy.
