Phone Health check list
A phone Health Check is where we give your phone a full diagnostic check.
What's covered in the Health Check
Our in-store experts will run a diagnostic test on your phone which will look for any issues and give advice. They’ll also offer hints and tips on how to get the most from your device.
How to book a Health Check
Find your nearest O2 store and give them a call to book your Health Check. They’ll advise you on the best time to bring your phone in.
Your check list
1. Buy a good case and screen protector
That way your phone can handle accidental drops and dusty pockets without fear.
2. Keep your phone dry
Beware steamy bathrooms and wet raincoat pockets. Moisture can get into your phone and erode its parts – you may not even know for months. And water damage isn’t covered by your warranty.
3. Install updates
Updates often fix bugs and help keep your phone secure. Keep an eye out for update notifications so you can stay on top of it.
4. Back up regularly
Contacts. Messages. Photos. Back it all up whenever you can, in case your phone ever goes missing or faulty. Got cloud storage? Make use of it. It can do back- ups automatically and free up memory.
5. Avoid the heat
Steer clear of hot things like radiators and hot places like car dashboards. Most batteries don’t like extremes either, hot or cold, so aim for room temperature.
6. Use quality chargers
That charger that came with your phone, use it. It’s the one you can trust to look after your device properly. If you ever need a replacement, make sure you get one from a reputable supplier.
7. Turn it off now and then
Restarting your phone once a week will refresh its settings and kill unnecessary background tasks that clog memory. Plus phones often run clean-up tasks on start-up.
8. Keep some storage free
This can make a difference to the overall performance of your phone. If storage is getting tight, delete apps, photos or files you don’t need.
9. Run built in maintenance
If you’ve got a device maintenance feature, give it a run from time to time. It’s a good way to clean out clutter that you won’t know is there.
10. Don’t use battery apps
They may sound like the answer to your power-shortage problems, but often they’re no help at all. Installing them can slow your phone down.
