FAQs About the iPhone 4 Repairs

Here are some of the most common questions we get asked around iPhone 4 Repairs - select your issue and see what we can do for you.

My phone's touchscreen isn't responding. Do I need an iPhone 4 screen replacement?

iSmash can fit a high quality iPhone 4 replacement screen while you wait in store, but there may be some things you can do to get your touchscreen working first. If your touchscreen is intermittently working on your iPhone 4, it may be a software issue.
Firstly, turn the device off and on again, and if you are able to get your touchscreen working briefly, force close any apps that are running and delete any you've recently downloaded. If there is still no response, you may be able to do a factory reset by connecting your iPhone 4 to a computer - warning - this can erase data.
It may be that your iPhone 4 screen has some damage to the circuitry that is not visible. In this case contact is at iSmash and we will run diagnostics to identify the issue and if necessary fit a replacement screen while you wait.

My phone battery isn't holding charge as well as it used to. Does my iPhone 4 need a replacement battery?

As batteries age, they lose capacity and the ability to hold charge, but if it's draining in a very short space of time this isn't normal. There are some things to look for before resorting to a new battery:
It might be an app that is running in the background draining the power of your iPhone 4 battery. Force close all apps and uninstall any new ones you've recently downloaded to see if this helps.
Try emptying your iPhone 4 battery of all power, them charging it fully to recondition the cell.
If that hasn't worked, try removing the fully charged battery from the iPhone and leaving it out of the device for 24 hours. This isolates the battery from any other influences. If, when you put the battery back in the iPhone 4 the next day it has lost more than 15% power, you know that the battery has lost its ability to hold charge and a new one may be necessary. Contact iSmash and we will diagnose and confirm the issue, and can fit a brand new battery while you wait in store.
