Apple is set to unveil the iPhone 6S and iPhone 6S Plus at its September 9 event in San Francisco. The new devices are expected to go for sale on Sept.18. If you are planning to upgrade your older iPhone to the brand new iPhone 6S, you might have started exploring various trade-in and resale options for your current device.

iPhone 6S Upgrade: Where To Get The Best Value For Your Older iPhone

iPhone 6S trade-in programs

Getting the best value for your current phone can help fund the upgrade. But trade-in payouts fall significantly in the first few weeks of launch of a new iPhone. So, move fast to get a princely sum for your old iPhone, especially if it is in good condition. Here’s the list of services that offer great value for your older iPhone.

Gazelle

The Internet favorite is offering the Best Price Guarantee on the iPhone 5S, iPhone 6 and 6 Plus trade-ins until Wednesday, Sept.9. It guarantees to beat the trade-in prices offered by AT&T, T-Mobile, Verizon, Sprint, and even Apple. The company currently offers between $325-$480 cash for a used iPhone 6 or 6 Plus. The iPhone 5S fetches much lower, in the range of $150-$200 depending on the phone’s capacity.

Glyde

Glyde claims to offer prices that are 10%-20% higher than trade-in offers from Apple or Gazelle. It pays you at least $100 for the iPhone 5 and about $335 for the 5.5-inch iPhone 6 Plus. The payout could go higher depending on the configuration and condition of your iPhone. The company sends you a shipping kit to help you quickly sell your older device.

NextWorth

NextWorth’s trade-in program is quite similar to that of Gazelle. You can sell phones as old as the iPhone 4. Its quotes are valid for 30 days. So you can lock in a trade-in price and ship your old phone after receiving the new iPhone 6S or iPhone 6S Plus. You can get about $320 for a 16GB AT&T iPhone 6, and up to $480 for a 128GB iPhone 6 Plus, though it largely depends on the condition and model of your phone.

Amazon

If you don’t mind taking payment in gift card credit, Amazon’s trade-in program could be a good option for you. You have to answer a few questions about the condition of your device and enter your shipping address. You can print out a shipping label to ship your device for free. Amazon pays up to $390 for a 16GB iPhone 6 Plus.

Apple

Apple has partnered with Brightstar to offer a Reuse and Recycling program. You can trade in your old iPhone online or at an Apple Store. Apple isn’t accepting the iPhone 6 and 6 Plus online, though. Brightstar currently offers $165 Apple Store Gift Card for a 64GB iPhone 5S.

Avoid trade-in programs offered by telecom carriers. They have confusing terms and conditions, and often offer lower prices than other services.
