At a glance
If you want the biggest, best iPhone Apple made in 2020, the refurbished iPhone 12 Pro Max is it. It has the largest screen in the 12 range, the longest battery life, and a camera system that went further than any other iPhone that year.
The iPhone 12 Pro Max has a 6.7-inch Super Retina XDR OLED display, a triple 12MP camera with 2.5x optical zoom, and the A14 Bionic chip. It still supports iOS 26, making it a serious phone at a very reasonable refurbished price in 2026.
If you are comparing iPhone 12 Pro Max deals in the UK, the main difference is testing and aftercare. A professionally refurbished iPhone from The Big Phone Store gives you clear grading, battery checks, warranty cover and support after purchase.

Features and Improvements
The iPhone 12 Pro Max is the best-value large iPhone from the 2020 generation. You get a massive screen, strong battery life, and advanced camera stabilisation, all for a lower price than newer Pro Max models.
Feature | What This Model Offers | What You Notice |
|---|---|---|
Screen | 6.7-inch Super Retina XDR OLED, 2778 x 1284 resolution | A large, sharp screen with excellent colour accuracy. Good for video, gaming, reading and photo editing. It has better contrast, more accurate colours and improved outdoor visibility compared to the iPhone 11 Pro max. |
Camera | Triple 12MP Wide, Ultra Wide and Telephoto cameras, 2.5x optical zoom | The most capable camera system Apple offered in 2020. Sensor-shift stabilisation produces noticeably sharper shots. |
Battery life | Up to 20 hours video playback | The strongest battery life in the iPhone 12 range, good for a full day of heavy use. |
iOS / Software | Supports iOS 26, still receiving updates | Fully supported in 2026 with all current iOS security and feature updates, keeping your data secure and your phone up to date. |
Dimensions | 160.8 x 78.1 x 7.4mm, 228g | Large and premium, but heavy compared with many newer iPhones. The large screen makes reading and watching video more comfortable. |
Size Note: The iPhone 12 Pro Max is quite big and heavy at 228g. It's one of the larger phones in the refurbished Apple range, so it's not the right choice if you want something compact or comfortable in a small pocket. The iPhone 12 Pro gives you most of the same features in a smaller body.
The Big Phone Store Team Summary: The main reasons to choose the 12 Pro Max over the 11 Pro Max are display quality, camera stabilisation and connectivity. The screen is noticeably more vivid, and 5G gives you faster mobile data.
If I were to buy any phone from the 12 range, it would be the 12 Pro Max.
At refurbished prices, the difference in price is nowhere near as big as it was at launch, but the upgraded features are still there.
One of the main things that suffer with older phones is the camera quality, but not here. The 12 Pro Max has a solid camera, even by today’s standards. It still supports the latest iOS updates, so you’re not missing out on anything yet.

Great company, I bought an iPhone 12 Pro Max through them, Royal Mail managed to confuse the delivery but this was sorted easily and the BPS customer service was great. Highly recommend
Ordered a pristine iPhone 12 Pro Max and the quality was better than expected. Ordered it at 12:53 and surprised by speed of delivery. Got it next day via Royal Mail before 1pm at no cost. I could have had it at 8am if I picked up from local sorting office.
