There are some mishaps that befall your phone that there’s really no cure for but to bring it in for repairs. Unless you want to spend your life squinting through cracks or cellophane tape to see your apps, for example, you’re going to need to get that iphone 6 screen replacement. But other glitches you may be able to handle yourself.
If your battery isn’t giving you as much usage time as it used to, try recalibrating it: let it go all the way down to 0%, charge it all the way up to 100% without using it, then repeat both steps. You may find that the battery indicator gets a better sense of how much juice is actually left and gives you more time. It’s also worth checking the charging cables you’re using; off-brand wires may be doing a poor job of charging your battery and put a dent in your usable power. And a little lint in your battery port can keep any cord from charging it correctly.
When you’re using an app and your screen freezes, you may be able to solve the problem by double-tapping the home button and swiping away the image of the troublesome app to close it. Open it again and see if the problem’s solved. If not, try a reboot: hold down the home and power button until the screen goes black, wait for it to come back on again, and then let go. Generally, this will make everything work just as it should once again.
How many apps and songs and movies and messages do you have on that thing anyway? Every device has its limits. Cure a sluggish phone by pruning away items you never or rarely use. Maybe you don’t really need 20 screens of apps after all.
There’s nothing like the satisfaction of fixing a techie problem yourself. Doesn’t hurt that it may save you time and money as well.
