iPhone OLED burn in: causes, how to check, and what it means for grading (2026)

iPhone OLED burn in is permanent, uneven pixel wear. On an OLED each pixel lights itself, so pixels that ran a static bright element for thousands of hours dim faster than their neighbours, and that gap shows on a plain field. Check it in seconds with a solid grey image. Because the wear is inside the panel it cannot be relaminated away, and it lowers what a broken original iPhone screen is worth on buyback.

What causes iPhone OLED burn in in 2026?

iPhone OLED burn in is caused by uneven pixel aging. Each OLED pixel makes its own light, and light output drops as the pixel runs. A status bar, a keyboard, or the home indicator sits in the same place for thousands of hours, so those pixels age faster than the rest. The result is a faint ghost of that static element that shows on any solid colour. LCD does not do this, because an LCD is lit by one shared backlight behind the whole panel.

How do you check an iPhone screen for burn in?

Check an iPhone screen for burn in with a full screen solid grey image at steady brightness. Grey shows uneven wear that white and black hide. Look for a darker ghost of the status bar, the keyboard block, or the navigation bar. Turn off True Tone and auto brightness first so the field stays even. Fixera keeps a grey field pass on record for each panel, so every unit's image and shadow result is logged individually.

Run through it in this order:

1. Set brightness to a fixed mid level and disable True Tone.
2. Display a plain mid grey full screen image.
3. Tilt the panel under light and look for a stationary ghost.
4. Repeat with a plain red and a plain blue field, since colour shift can hide in one channel.
5. Separate real burn in, which stays put, from image retention, which fades within a minute or two.

What burn in patterns show up most on iPhone OLED panels?

The most common iPhone OLED burn in patterns are the status bar strip at the top, a rectangular keyboard ghost in the lower third, and a faint home indicator or navigation bar near the bottom edge. All three come from static UI that almost never moves. A separate fault, corner or edge shadow, looks similar on grey but comes from panel or flex damage rather than pixel wear. Both drag a buyback grade down the A to E ladder.

How does burn in affect an iPhone screen buyback grade?

Burn in lowers an iPhone screen buyback grade rather than rejecting the panel outright. Fixera grades broken original iPhone panels on an A to E ladder, and every grade from A to E still shows a full image and takes touch across the whole surface. Faint burn in pushes a panel down toward E, the floor grade. Heavy burn in or deep shadow pushes it near scrap value. A panel is only rejected, not graded, when the image is dead, touch is dead, or the panel is aftermarket or already reglassed. Fixera grades every buyback panel on the same published rubric it pays on, fault by fault, so you can sort before you pack. The full rubric is on the grading rules page, and the grade ladder is broken down in iPhone screen grades explained for sellers.

Can a refurbished iPhone panel with the glass changed still have burn in?

A refurbished iPhone panel with the glass changed can carry burn in in theory, because the original OLED panel is reused and only the front glass and OCA are replaced. That is exactly why Fixera tests every refurbished unit for image retention and shadow one by one before it ships, not by batch sample. A panel with visible burn in does not go out as sellable stock. Every refurbished original display Fixera sells carries a 90 day warranty, and the shop labels each unit by build only, glass changed, touch replaced, or flex replaced, with no grade on shop stock.

Does iPhone LCD burn in the same way as OLED in 2026?

iPhone LCD does not burn in the same way as OLED. An LCD is lit by one backlight behind the whole panel, so there are no self lit pixels to age unevenly, and static UI does not etch a permanent ghost. LCD panels have their own faults instead, such as backlight bleed, pressure marks, and stuck pixels. The last iPhones with LCD are the iPhone 11 and the iPhone SE line, so most current stock is OLED. The full split is in OLED vs LCD iPhone screens explained.

FAQ

Is iPhone burn in the same as image retention?

No. Burn in is permanent uneven pixel wear that stays on a grey field. Image retention is a temporary ghost that fades within 1 to 2 minutes. Only burn in permanently affects a buyback grade.

Does burn in make a broken iPhone screen worthless?

Not automatically. Faint burn in drops a panel toward the E floor grade, and all grades from A to E still show a full image and take touch. Only a dead image, dead touch, aftermarket, or already reglassed panel is rejected outright.

Can burn in be fixed or removed from an OLED panel?

No. Burn in is physical wear inside the OLED, so it cannot be relaminated or reglassed away. That is why Fixera checks every refurbished unit for retention and shadow before any panel ships with its 90 day warranty.

What is the fastest way to check for burn in before I sell a batch?

Display a full screen mid grey image at a fixed brightness with True Tone off, and sort any panel with a stationary ghost into a lower grade before you pack.

Where does Fixera fit?

Fixera is the trade name of Fonora OU, a Tartu, Estonia supplier of refurbished original iPhone displays and an EU buyback for broken original iPhone and Samsung screens.
