In this comprehensive guide, we reveal all the key steps to prepare your smartphone to get the best possible price.
Why prepare for your sale?

Furthermore, a smartphone in good condition, clean and functional, will be more attractive to potential buyers and will help you prepare for the trade-in of your old smartphone , allowing you to get a better price. Finally, being well-prepared simplifies the transaction and saves you time.
Backing up your data: a crucial step
Before handing over your smartphone, it is essential to back up all your important data (contacts, photos, videos, etc.). You can use various tools for this:
- The cloud: Online storage services like Google Drive, iCloud or Dropbox allow you to back up your data simply and securely.
- A computer: You can also transfer your data to your computer using a USB cable.
Resetting your smartphone: an essential
Once your data is backed up, perform a factory reset of your phone. This will erase all personal information and restore your device to its original state. To do this, go to your phone's settings and follow the instructions.
Assessing the true value of your phone
To find out the value of your smartphone, several options are available. You can use the online valuation tools offered by many specialized websites. Simply enter your phone's specifications (brand, model, condition, etc.) to get an estimate.
You can also compare the prices offered by different players in the buyback market to get an idea of the market.
Finally, specialist forums can be a valuable source of information for finding out the prices charged for similar models.
Choosing the right sales method: which solution should you choose?
The choice of sales method for your smartphone will depend on several factors: how quickly you want to sell, the price you want to get, and the level of involvement you are willing to have.
Mobile phone trade-in by an operator or retailer
This option offers a quick and easy way to sell your old smartphone. Indeed, most phone operators and specialist retailers offer trade-in services.
You can go directly to the store with your device and get an immediate estimate. The main advantage lies in the ease of the transaction: no need to create an ad, manage communication with potential buyers, or deal with shipping.
The principle is simple: you bring your phone to the store, the operator or retailer quickly examines it to assess its condition and offers you a price. If you accept, the transaction is completed on the spot, and you generally receive a voucher to use towards the purchase of a new phone or a bank transfer.
The advantages of a takeover by an operator:
- Speed: You get an estimate and can finalize the sale in minutes.
- Simplicity: No administrative procedures are required.
- Security: The transaction is secure and you don't have to worry about potential scams.
- Standard exchange: You can exchange your old phone for a new model and benefit from promotions or special offers.
Online sales
Online platforms like eBay or LeBonCoin offer greater freedom to set your price and reach a wider audience. However, this method requires a greater time investment
- Writing a detailed ad: It is important to accurately describe your smartphone and its features to attract potential buyers.
- Taking quality photos: Clear and well-framed photos are essential to showcase your device.
- Managing exchanges: You will need to answer buyers' questions, negotiate the price, and arrange shipping.
Websites specializing in refurbishment
These websites buy used smartphones and refurbish them. The main advantage is the simplicity of the transaction: you send your smartphone and receive payment. However, the prices offered may be lower than those found on platforms like eBay.
Private sales
Selling between individuals, for example via social media or dedicated groups, allows you to set your price and negotiate directly with the buyer. However, this method requires greater vigilance to avoid scams. It is recommended to prioritize face-to-face transactions and to ask the buyer for identification.
Preparing your smartphone for a successful restart: deep cleaning and essential checks
Before handing over your smartphone, it's crucial to prepare it properly. A clean, functional, and well-presented device will be much more valuable to the buyer.
Cleaning: an often neglected step
A dirty smartphone can leave a bad impression and lower its value:
- Turn off your device before starting the cleaning process.
- Use a microfiber cloth lightly dampened with soapy water to clean the screen and case. Avoid harsh cleaning products that could damage the coatings.
- Clean the ports and connectors with a soft-bristled toothbrush to remove dust and debris.
- Disinfect your device with a disinfectant wipe to eliminate bacteria.
Things to check before selling
To ensure your smartphone is in perfect working order, take the time to check the following:
- The screen: Check for scratches, dead pixels or smudges.
- Touchscreen: Make sure the screen responds well to the touches.
- Buttons: Check the operation of the volume, power, and other physical buttons.
- The camera: Take some photos and videos to check image quality and focus.
- Speaker and microphone: Make a call and record a voice note to check that the speakers and microphone are working properly.
- The battery: Make sure the battery holds a charge well and that there are no overheating problems.
- Applications: Uninstall all unnecessary applications and delete personal data.
Accessories, an added advantage
Don't forget the accessories! The more original accessories you have (charger, headphones, case, etc.), the more valuable your smartphone will be. Make sure they're in good condition and include them in the sale.
By following these tips, you'll maximize your chances of getting the best price for your smartphone. Don't hesitate to take photos of your device from different angles to show its overall condition.
