Why comparación de iPhone 11 y 12 still matters
Neither is Apple's latest line, yet both dominate second-hand listings on Wallapop, Back Market and carrier refurb channels in Spain. Buyers want iOS support without flagship pricing. A structured comparación de iPhone 11 y 12 avoids paying iPhone 12 money for cosmetic upgrades you will not notice, or saving euros only to miss 5G where you commute daily.
Display and body design
iPhone 11 uses a six-point-one-inch LCD Liquid Retina display—bright and reliable but without OLED deep blacks. iPhone 12 switches to Super Retina OLED on the same size class, improving HDR video and dark-mode reading. Externally, iPhone 12 adopts flat stainless-style edges and smaller bezels; cases do not interchange. Drop both without a case in store to see which grip feels secure.
Performance: A13 versus A14
iPhone 11 runs Apple A13 Bionic; iPhone 12 steps to A14 with modest CPU gains and better efficiency for the same tasks. Everyday messaging, Safari and banking apps feel similar; heavy video editing or future iOS versions tilt toward iPhone 12. Check Apple's iOS compatibility chart—both may share support windows today but diverge on later major releases.
5G and connectivity in Spain
iPhone 11 tops out at 4G LTE, still adequate on many Spanish MVNO plans. iPhone 12 adds 5G including band n78 common on Movistar, Orange and Vodafone. If you keep phones three years or more, 5G future-proofs outdoor speeds; if you mostly use Wi-Fi at home and office, LTE on iPhone 11 may suffice and save purchase cost.
Camera and video for everyday use
Both offer dual twelve-megapixel rear cameras on standard models—wide and ultrawide. iPhone 12 improves Night mode and HDR video processing thanks to chip and sensor tweaks. For social photos and document scanning the gap is modest; content creators shooting handheld 4K Dolby Vision notice iPhone 12 advantages more.
Buying refurbished in Spain
Inspect battery maximum capacity in Settings, test Face ID, speakers and True Tone. Confirm the seller provides VAT invoice and at least twelve-month warranty for refurb. MagSafe chargers and wallets are optional extras—budget them only if you choose iPhone 12. Screen replacements cost more on OLED—factor Apple or authorised service quotes before buying a cracked unit cheaply.
