iOS 8 Fixes – Battery Drain and WiFi
I recently updated my iPad 2 to the new ios 8 software. A whopping 899mb install no less. After installation completed I noticed right away there were performance issues, sluggish response, sticky scrolling, and a few others like missing icons. I assumed it was maybe due to the fresh install so I did a quick reboot. That helped a little, but still not great. I realize I am using an older device so I should expect some performance loss, but not this bad.
My biggest issue is the battery drain. I normally leave my iPad on standby all the time, I rarely power all the way down. With ios 7, It would take a week or two before it would need charged with little usage. With ios 8, I dropped by 60% in 2 days without hardly using it. hmm…
So I did my research on various sites including Apple and found these tweaks:
1. Turn off parallax
Parallax is fun, but it’s the definition of “extra.” And maybe it even makes you dizzy. Who needs it? Not you. You can turn it off in accessibility settings, by going to Settings>>General>>Accessibility and setting Reduce Motion to on.
2. Turn off AirDrop/Bluetooth if you’re not going to use it
AirDrop is great when you are AirDropping. The rest of the time it’s just fidgeting in its seat, looking for another device to play with. Turning it off is easy, just swipe up your Control Center, and hit the toggle.
3. Stop searching for Wi-Fi
There’s no need to have your phone searching for Wi-Fi when there’s no trusted network in sight. You’ll save yourself some trouble if you get in the habit of turning of Wi-Fi from the Control Center when you leave the house. Alternatively, you can go to Settings>>Wi-Fi and turn Ask to Join Networks to off. This way your phone will hop on Wi-Fi networks it knows, but won’t look around for more without direct orders.
4. Disable location services (for apps that don’t need it)
Google Maps needs to know where you are, yes. But Facebook? Hop over to Settings>>Privacy>>Location Services to get a full list of the apps that are asking about where you are. You can probably turn off about half, and cut down on a lot of GPS polling.
5. Turn off background app updates
Immediate app updates are rarely a huge deal, but having enough battery always is. Go to Settings>>iTunes & App Store and then scroll down. You’ll see Updates under Automatic Downloads. Turn it off. Just don’t forget to stop by the App Store and update manually now and then. While you are here you can also turn off automatic updates for music in order to prevent U2 albums from appearing on your phone now and in the future.
6. Turn off background app refreshing
The brutal downside of good multitasking is running things in the background (duh). But if you go to Settings>>General>>Background App Refresh, you can disable background-runnin’ for the apps that aren’t important. Or all of them if you want to go all the way.
7. Disable auto-brightness
Chances are, auto-brightness keeps you more well-lit than you need to be. You can shut it off and get your mood-lighting on by going to Settings>>Display & Brightness and flipping the toggle. While you’re there, crank that backlight alllll the way down, or as far down as you can handle. If you step outside, that’s what the Control Center is for.
8. Go on a push notification diet
Not every app needs to push its notifications; that stuff takes power. Go to Settings>>Notifications and scroll down to the Include section. Then go on a toggling spree.
9. Don’t push fetch
If your email isn’t that important, or you have a couple of accounts, go turn the low-priority ones to Fetch instead of Push, which means your phone will go retrieve mail at set intervals instead of having it pushed to you every single time Uncle Harry or a spambot blasts you. This one is pretty dependent on how often you get emails and how crucial they are, so you’ll have to feel it out, but you can set to fetch in Settings>>Mail, Contacts, Calendar>>Fetch New Data
10. Turn off 4G (if times are tough)
Disabling 4G is going to hurt a little but, but desperate times can call for desperate measures and LTE is a battery-burner. You can choke off the data-hose by going to Settings>>Cellular>>Enable LTE/Enable 4G
So that takes care of the battery, but there are also some complaints of Wi-Fi issues as well. I did some digging and here are some tips to fixing your Wi-Fi issue with ios 8.
1. Reset iOS 8 Networking Settings
Resetting network settings is often the be-all-end-all advice for resolving many network performance issues and wi-fi related problems that pop up with iOS. The reason is quite simple; it dumps all settings, caches, DHCP info, and any other settings or custom data that has been set on the iPhone or iPad.
To reset your iOS 8 Network Settings, visit the Settings app, head to “General”, then to “Reset” and choose “Reset Network Settings”.
This will force the device to reboot, and it also dumps any wi-fi passwords you have stored, so be ready to enter those again. This should always be this first thing you do any time you experience networking related issues with an iOS device – it works fairly reliably.
2. Disable a Wi-Fi System Service Setting
If resetting network settings did nothing for you, you may want to experiment with toggling off a wi-fi system setting. MacRumors reports that some users have had a positive impact by disabling this setting, though it’s not entirely clear what exactly this specific setting controls (it is possible it’s a wi-fi based geolocation service, hence why it’s in Location Services settings).
Head to the Settings app, go to “Privacy” and then to “Location Services”, where at the bottom you will find “System Services”, then flip the switch to disable Wi-Fi Networking. This does NOT turn off wireless networking in iOS.
Then try and join the network again, some users report this to be a success.
Hope this helps you solve your ios 8 battery and wi-fi issues. Feel free to comment below with any additional fixes or tips you may have.
