Follow the 80-30-3 Rule: How to Find a Good Used Cell Phone

You don’t necessarily have to buy a new smartphone. Used cell phones are not only more environmentally friendly, they also help you save money. Find out what you should look out for when buying used cell phones here. So you can make sure you made the best choice to also Play Casino Games Online when you are on the streets.

The production of cell phones poses numerous ecological and social problems. For example, smartphones are made from raw materials whose extraction is often associated with environmental pollution and catastrophic working conditions. Cell phone production is also very energy-intensive and has a correspondingly poor environmental footprint.

For numerous reasons, it would therefore actually be more responsible not to own a cell phone at all. However, this is hardly conceivable for the majority of people. Second-hand smartphones are a compromise: if you buy a used cell phone, you extend its life cycle and delay it, ending up as electronic waste. Producing fewer new devices helps to conserve resources and reduce CO2 emissions. That can help to decrease your emission footprint on our planet. So try it right now for your next phone!

Purchasing Used Cell Phones: A Purchase with Risk?

Buying a used cell phone can also involve risks for buyers. For example, you may not be able to see at first glance what scratches the phone has, how good the battery performance is or how well the touchscreen still works. This is a particular problem when you buy second-hand items online.

If you purchase the used device from an online retailer, the risks are manageable. In this case, you can make use of your right of withdrawal and return the cell phone within two weeks. You may only have to pay the return costs yourself.

However, if you buy a cell phone from a private seller, the right of withdrawal does not apply. Private individuals are generally not obliged to take back or exchange goods. In this case, it is therefore even more important that you clarify some basic aspects before you decide to make the purchase.

How the 80-30-3 Rule Works

Follow the 80-30-3 rule if you want to buy used cell phones. The 80-30-3 rule summarizes three important aspects that you should consider when buying a used cell phone:

80 percent battery power: A cell phone is of little use if the battery is constantly empty and you have to charge it several times a day. As a guideline, even a used cell phone should have a battery capacity of at least 80 percent. You can find out how high the battery capacity is for iPhones in the settings. For Android devices, you can use the CPU-Z app, for example. This estimates how well the battery of a cell phone still works.

30 percent savings: A used cell phone should be at least 30 percent cheaper than the new price.

 After all, you are accepting some defects for the lower price.

3 years old: Make sure that the used cell phone is no more than three years old. Otherwise, you run the risk that updates will no longer be available for the older model.

Also make sure that the seller has uploaded informative photos of the cell phone. This is particularly important for private individuals. After all, you can no longer return the phone. Always read the item description carefully. If information or photos are missing, you can usually easily contact dealers and private individuals and ask them questions directly or request photos of described defects, for example.
