The iPhone 6s and iPhone 6 Plus have officially entered “obsolete” territory in 2026 . Apple no longer offers repairs or software security updates for these iconic models . Yet, demand persists—driven by nostalgia, collectors seeking vintage devices, and budget-conscious buyers who simply want a basic iPhone for calls and light use.
If you’re determined to buy an iPhone 6s or 6 Plus in 2026, you won’t find them new in stores. Your only options are refurbished marketplaces, second-hand platforms, and specialized vintage electronics retailers. This guide covers the best places to look, what to check before buying, and the risks you need to understand.
Quick Reality Check: iPhone 6s and 6 Plus in 2026
Key takeaway: These phones are for collectors, retro enthusiasts, or extremely basic use—not for anyone needing modern app support, security, or daily driver reliability.
Top Platforms to Buy iPhone 6s and 6 Plus Online
1. Specialized Refurbished Marketplaces
These platforms offer the most buyer protection, warranties, and quality grading.
Back Market
Best for: Buyers wanting warranty coverage and vetted sellers

2. Specialized Second-Hand Electronics Retailers
These dedicated used electronics stores provide detailed condition reports and transparent grading.
Janpara (Japan)
Best for: Buyers comfortable with international shipping and detailed condition transparency
Janpara is a major Japanese second-hand electronics chain with 57 stores nationwide and online sales . They provide exceptionally detailed listings for vintage iPhones.
Why it’s notable:
- Extremely detailed condition descriptions (screen color unevenness, frame scratches, battery health percentage with month recorded)
- Clear OS version listed (e.g., iOS 13.4.1, iOS 15.1)
- Network usage restrictions clearly marked
- “As-is” sales with limited returns—buyer beware
Sample listings:
- iPhone 6s 64GB with 92% battery health, screen unevenness and scratches
- iPhone 6s 32GB (SIM unlocked) with 89% battery health, includes original accessories
- iPhone 6 Plus 16GB with 96% battery health, screen color unevenness
Considerations: Listings are in Japanese, international shipping policies vary, and returns are limited on some items.
3. Peer-to-Peer Marketplaces
These platforms connect individual sellers with buyers but offer less protection.
Price.com.hk (Hong Kong)
Best for: Buyers in Asia comfortable with local meetups and cash transactions
Price.com.hk is a Hong Kong price comparison and classifieds platform where individuals list used electronics .
Recent listings:
- iPhone 6 Plus 64GB Gold, “95% new, battery replaced at Apple Store,” minor scratches, HK$1,800
- iPhone 6 Plus 128GB, “near mint” condition, HK$3,200 (sold)
Considerations: No buyer protection, cash transactions typical, language barriers possible.
eBay
While not specifically mentioned in search results, eBay remains a major global marketplace for vintage electronics. Look for sellers with:
- 99%+ positive feedback
- Detailed photos of actual device (not stock images)
- Clear return policies
- 12+ month warranties from professional refurbishers
What to Check Before Buying iPhone 6s or 6 Plus in 2026
1. Battery Health
Batteries degrade over time. For a 10+ year old iPhone 6s or 11+ year old iPhone 6 Plus, original batteries are likely below 80% capacity.
Ask sellers for: Screenshot of Settings > Battery > Battery Health showing maximum capacity. Janpara listings often include this with month recorded .
2. Physical Condition
Vintage iPhones show wear. Understand grading terminology:
- Screen issues: Color unevenness, dead pixels, deep scratches
- Frame damage: Scratches, dents, worn edges
- Camera condition: Scratches affecting photo quality
3. OS Version and App Compatibility
iPhone 6s runs iOS 15 maximum ; iPhone 6 Plus tops out at iOS 12 . Many modern apps require newer iOS versions and won’t run. You’ll be limited to older app versions—if they’re still available in the App Store.
4. Network Compatibility
Check SIM lock status. Some listings specify “SIM lock removed” or “network usage restriction: ○” indicating unlocked status . For international purchases, verify carrier compatibility in your country.
5. Return Policy and Warranty
- Back Market: 1-year warranty, 30-day returns
- Janpara: Some items “no returns due to no warranty”
- Peer-to-peer: Typically “as-is” with no returns
6. Activation Lock
Always verify the phone is not iCloud-locked. Ask sellers to show the setup screen with no activation lock before purchase.
Security Warning: Why These Phones Are Risky
Both the iPhone 6s and 6 Plus no longer receive security updates . This creates genuine risks:
- No new security patches: Vulnerabilities discovered after 2025 remain unpatched
- Higher hacking risk: Attackers can exploit known vulnerabilities
- Financial data vulnerable: Avoid entering banking details or making purchases
- Limited safe use: Experts recommend turning off Wi-Fi and removing SIM cards for offline-only use
For practical daily use, cybersecurity experts strongly recommend choosing iPhone 11 or newer models that still receive iOS updates .
