First things first: after you update your iPhone to iOS 11, don’t panic. Your phone is going to slow down and your battery life will take a hit for at least a day or two as your iPhone re-indexes. After that, you’ll see a marked improvement in speed and battery life probably.

Where speed is concerned, some older iPhone models will never run as fast on iOS 11 as they did with iOS 10 installed. Efficiency improvements in upcoming iOS 11 updates could help things down the road, but right now you’re stuck. That said, there are a few things you can do to speed your iPhone back up if the slowdown starts to get to you.

First, clear up space. Go to Settings > General > iPhone Storage. Under Storage, tap Manage Storage. You’ll see several ways in there to clear up space, including an easy way to delete large attachments in Messages, which is often a big culprit when it comes to wasted space. You’ll also be able to see which apps are taking up all your storage in this section, and you can enable a feature that automatically uninstalls apps you never use when you’re running low on space. App data will be retained, so you’ll still have everything if you ever decide to reinstall the app.

Freeing up space could have a big impact on your phone’s performance. Once you’ve done the legwork above, try to keep as much unutilized storage as possible.

One way to do that is to offload your photos and videos to a backup service like Google Photos as often as you can. And in between backups, you can save some space by enabling Apple’s new photo encoding. Go to Settings > Camera > Formats and switch to “High Efficiency.”

In some cases, you can also speed up your iPhone a bit by cutting back on the number of apps that can refresh in the background (Settings > General > Background App Refresh) and access location services (Settings > Privacy > Location Services), but neither will have a big impact unless you have apps that aren’t performing as they should.

One other thing that will help, however, is to cut back on the transition animations in iOS 11. Go to Settings > General > Accessibility > Reduce Motion and toggle it to ON.

Many of you may know about this, but there is an app for your phone that lets you track the Maui Bus. It is intended for riders who want to see where the bus is and when it will arrive at various stops. The app is called Transloc Rider, which can be downloaded from the App Store.

To use the new Dark Mode, go to Settings, General, Accessibility, Vision, Display Accommodations, Invert Colors, Smart Invert on. Get ready for an X-ray experience just for fun.

The new Firefox 56 arrives with screenshot feature, send tabs and drops flash support for Android.
