Repair or replace?
A damaged smartphone does not always need to be replaced. Start by checking what is actually damaged, how important the device is in daily life, and how long you want to keep using it.
Repair may make sense when only the display, battery, charging port, or back is affected and the device still meets your needs. Replacement may be more suitable when several expensive faults are present or important parts are unavailable.
Check the battery, display, and charging port
For a used or damaged device, check at least these functions:
- Battery: runtime, unusual heat, and visible damage
- Display: brightness, touch response, dead pixels, and cracks
- Cameras, flash, speakers, and microphone
- Charging port and a stable connection with a suitable cable
- Mobile network, Wi-Fi, Bluetooth, and GPS
- Buttons, Face ID, or fingerprint sensor where available
- Body for bending, moisture marks, or loose parts
Used, open-box, or refurbished
These labels are not used consistently everywhere. Ask about the exact condition, included items, battery information, and the applicable warranty or statutory rights.
- Used: The device has been used before; wear and technical condition should be described and checked.
- Open-box: The packaging has been opened; the exact condition should be explained clearly.
- Refurbished: The device has been tested and may have been serviced; the scope and outcome of testing should be clear.
Check activation locks and accounts
Before buying a used iPhone or Android device, make sure it has been removed from the previous account and can be reset and set up again.
After a reset, an unknown Apple or Google account must not block setup. Proof of purchase or a traceable source is also useful.
Back up data before repair, trade-in, or handover
Before a repair: back up your data and follow the repair provider's instructions. For a trade-in, donation, or handover, also complete the account-removal and reset steps below:
- Back up photos, contacts, messages, and important files, then check the backup
- Account for authenticator apps, passkeys, and banking access
- For a trade-in, donation, or handover, remove the SIM and memory card
- Only for a trade-in, donation, or handover, turn off device tracking and remove the Apple or Google account
- For a trade-in, donation, or handover, sign out of payment and banking apps
- For a trade-in, donation, or handover, reset the device only after the backup has succeeded
Settings for longer use
A few simple settings can improve security and everyday use:
- Enable automatic updates where available
- Use a device lock and two-factor protection
- Set up regular backups
- Adjust text and display size to your needs
- Remove apps and permissions you no longer need
- Check chargers and cables for damage
