Quite a specific guide this week for those who are having battery woes on the iPhone 5, rejoice, there may be a solution. Plus we visit all the normal stops on the Keitai express including Winston, the scary press shot and of course the retro video of the week.

There was a little issue with the iPhone 5 that meant certain handsets had weaker batteries that died off quicker than other handsets.

Apple acted to make up for it and offered free replacement batteries and that's still going on right now. It's only for a limited time though, if you're eligible you've only got until January 2016 to switch it out.

Here are the steps to make sure your phone is eligible and how to replace it.

First up we need to make sure your phone is eligible. You need to have bought the phone between September 2012 and January 2013 - Apple will know this from what serial number your phone has. Your phone also has to be in working order and have battery issues - Apple is bound to check this out beforehand in the testing process.

To make sure you're eligible you can enter your serial number into the box on this site. To find your code you should press Settings > General > About and then look for the devices serial number which you can copy and paste.

The next step is to book up an appointment at the genius bar. Then you'll be ready for them to check your phone is eligible and get on with the process.

Now it's time to prepare the phone for your appointment. They're going to need it cleared so back up all your data to iCloud and then turn off Find my iPhone. From there you can delete everything on the phone - don't worry, you've backed it up - so press Settings > General > Reset and Erase all Content and Settings.

That gives the Apple store a fresh canvas to work with.

The last step is to remember although the service is usually free they may need your phone to be in tip top shape to continue. Therefore they may need to do some repairs if say, your screen is cracked. That means it could end up costing you a little to replace the battery - but Apple will tell you that before they go through with the repairs.
