Apple iPhone 15 Plus (Refurbished) – SIM-Free, Grade A & 18-Month Warranty
If you've ever wanted a proper big-screen iPhone without paying Pro Max prices, the iPhone 15 Plus is the one that makes that happen. Apple launched it in September 2023 alongside the standard iPhone 15, and the Plus does exactly what the name suggests—it builds on everything that makes the iPhone 15 popular and gives you more of what people actually want. More screen, more battery, and the same capable hardware, just in a format that suits people who'd rather not squint.
The camera is where the 15 Plus made the biggest leap from the generation before it. The jump to a 48MP main sensor, up from 12MP on the iPhone 14 Plus, is one of those upgrades that genuinely shows up in everyday photos rather than just on a spec sheet. More detail, better low-light performance, and Apple's Photonic Engine processing doing the hard work behind the scenes to make sure shots look natural rather than over-processed. The 12MP ultrawide completes the dual-camera system, while the 12MP front camera handles Face ID and selfies with ease. The iPhone 15 Plus records standard video at up to 4K 60fps, while Cinematic mode supports up to 4K at 30fps for smooth, professional-looking depth effects.
Then there's the battery, and this is really where the 15 Plus earns its keep. Apple rates it at up to 26 hours of video playback, and Consumer Reports independently tested it at 53 hours of total use—the longest of any smartphone they tested that year, including newer models. Those aren't just marketing numbers — that's a phone that genuinely lasts all day and then some for most people. Add USB-C charging (finally replacing Lightning), up to 20W wired and 15W MagSafe wireless, and a 6.7-inch Super Retina XDR OLED display with Dynamic Island, and you've got a phone that offers an outstanding balance of features, battery life, and value at a sensible price.

Frequently Asked Questions
The core hardware is the same — same A16 Bionic chip, same 48MP camera system, same features. The difference is size and battery. The Plus has a 6.7-inch display versus the standard 15's 6.1-inch and a bigger battery that Apple rates at 26 hours of video playback compared to 20 hours on the smaller model. If screen size and battery endurance matter to you, the Plus is worth the extra.
It means the phone has been professionally inspected, tested across every function, repaired where needed, and restored to full working condition before it's listed for sale. It's not a wiped and reboxed device—it's one that's been properly checked, fitted with a new battery, and only listed once it passes every test. You also get a genuine 18-month warranty, rather than relying on the uncertainty that often comes with buying privately.
Yes. Every refurbished iPhone 15 Plus from Fone4U comes with a brand-new battery, so you start with the full capacity the phone was designed to deliver. Battery degradation is the main reason secondhand phones feel tired—a new battery takes that off the table entirely.
Longer than most phones in its class. Apple's own figure is 26 hours of video playback, but Consumer Reports independently tested it at 53 hours of total use across their standard robotic testing protocol—the longest of any smartphone they tested, including phones released after it. Real-world use varies, but most people comfortably get a full day and then some, even with heavy use.
Yes. The iPhone 15 Plus features a 48MP main camera with Optical Image Stabilisation (OIS) and Apple's Photonic Engine, delivering sharp, natural-looking photos across a wide range of lighting conditions. The 12MP ultra-wide camera is ideal for capturing wider scenes. For video, it supports standard recording in up to 4K at 60fps, while Cinematic mode records in up to 4K at 30fps with beautiful depth-of-field effects for more professional-looking videos.
No. Buying refurbished doesn't affect how Apple delivers updates — a refurbished iPhone 15 Plus receives the same iOS updates as a new one. The phone itself is still well within Apple's support window, so you won't be left behind on software anytime soon.
Yes, and it's one of the key upgrades over previous non-Pro iPhones. The 15 Plus replaces Lightning with a USB-C port, meaning the same cable you use for your MacBook, iPad, or most modern Android phones works here too. Wired charging supports up to 20W, MagSafe wireless up to 15W, and standard Qi wireless up to 7.5W.
Yes. Every refurbished iPhone 15 Plus from Fone4U is fully unlocked and works with all major Irish networks, including Three, Vodafone, Eir, Tesco Mobile, and others.
An 18-month warranty is included with every refurbished iPhone 15 Plus from Fone4U. That's six months more than the standard 12-month cover most sellers offer, backed by an Irish-based support team. If something comes up after purchase, you're dealing with someone local.
The iPhone 15 Plus has an IP68 water-resistance rating, meaning it is designed to resist splashes, rain, and accidental immersion in water under controlled laboratory conditions. However, water damage is not covered under Apple's warranty.
No. Apple Intelligence is available only on the iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 series, and newer models. The standard iPhone 15 Plus does not support Apple Intelligence. However, it still offers excellent photography, strong performance, outstanding battery life, and full access to the latest compatible version of iOS.
