Getting a new iPhone is exciting, especially when you've found a refurbished model that fits your budget. But before you start downloading apps, transferring photos and making it your everyday phone, there are a few things worth checking.
The first day is the best time to make sure everything is working as expected. From inspecting the device and checking its battery to testing the camera, speakers and connectivity, a little attention now can help you avoid problems later.
If you've recently purchased a refurbished iPhone or are planning to explore Grest's refurbished iPhone collection, here's a practical first-day checklist to follow.
Start with a Physical Inspection
Before setting up your iPhone, take a few minutes to inspect its overall condition. Refurbished devices may have minor cosmetic marks depending on their condition grade, but there should be no unexpected physical damage.
Check the following:
-
Display: Look for cracks, unusual spots, discolouration or visible screen defects.
-
Body and frame: Inspect the edges, back panel and corners for dents or damage.
-
Buttons: Test the volume buttons, side button and mute or Action button, depending on the model.
-
Charging port: Check for visible damage and make sure the charging cable connects properly.
-
Camera lenses: Look for cracks, scratches or visible obstructions.
Compare the device's condition with the description provided at the time of purchase. If you're unfamiliar with how refurbished devices are evaluated.
Check Battery Health and Charging
Battery performance can make a significant difference to your everyday iPhone experience. Before relying on the device throughout the day, check its battery information.
Go to Settings → Battery → Battery Health & Charging on supported iOS versions.
Review the maximum capacity and check whether any battery-related service messages appear. You should also:
-
Charge the iPhone and check whether it charges normally.
-
Observe whether the battery percentage drops unusually quickly.
-
Check for unexpected shutdowns or overheating.
-
Make sure the charging cable and adapter are working properly.
Remember that battery capacity naturally reduces with use. A battery-health reading should be considered alongside the device's overall performance.
Test the Camera, Speakers and Microphone
Your iPhone might look perfectly fine, but it's important to check the features you'll use regularly.
Open the Camera app and test the front and rear cameras. Take a few photographs, record a short video and check whether the images are clear and the camera switches between available lenses properly.
Next, test the audio:
-
Play a video or audio track to check the speakers.
-
Make a test call to check the earpiece and microphone.
-
Record a voice memo and play it back.
-
Connect your headphones or AirPods, if available.
These simple tests can help identify issues before you start using the device regularly.
Check Face ID, Touch ID and Connectivity
Security and connectivity are essential parts of everyday iPhone use.
Depending on your iPhone model, set up and test Face ID or Touch ID. Make sure the feature recognises you consistently.
You should also check:
-
Wi-Fi: Connect to a network and browse a few websites.
-
Mobile network: Insert your SIM or activate your supported eSIM and check calling and mobile data.
-
Bluetooth: Connect a wireless accessory.
-
GPS and location: Open Maps and check whether your location is detected correctly.
If any of these features behave unexpectedly, investigate the issue rather than assuming it is normal.
Check the IMEI and Device Information
Your iPhone has a unique IMEI number that helps identify the device. It's useful to know where to find it and keep a record for reference.
Go to Settings → General → About to check the IMEI, serial number, model name and storage capacity.
You can also dial *#06# to display the IMEI on supported devices.
Compare the device details with the information on your purchase invoice or documentation. If anything doesn't match, contact the seller for clarification.
Update iOS and Set Up Your Apple Account
Once you've completed the basic checks, you can move on to setting up your iPhone.
Start by connecting to a secure Wi-Fi network and checking for available software updates under Settings → General → Software Update.
Then:
-
Sign in with your Apple Account or create one if you don't already have it.
-
Enable Find My iPhone.
-
Set up a passcode and Face ID or Touch ID.
-
Configure iCloud backup.
-
Transfer your contacts, photos and other important data.
-
Download apps from the App Store.
It's also a good idea to enable automatic software updates so your device can receive supported security and feature updates.
Keep Your Invoice and Warranty Details Safe
Don't overlook the purchase documentation after setting up your phone. Keep your invoice, warranty information and replacement policy somewhere accessible.
Read the applicable Grest warranty policy carefully, including what is covered, the duration and the process for raising a claim.
If you notice a functional issue during your initial checks, report it to the seller promptly. You can also review the returns, refund and replacement policy to understand the applicable conditions and procedure.
Keeping these details handy will make it easier to get assistance if you need it later.
