What is the LDI Indicator on the iPhone 11 Pro Max?
The LDI indicator stands for “Liquid Damage Indicator”. It is a small sensor located at the top of the iPhone 11 Pro Max near the earpiece that is designed to indicate if water or other liquids have entered the device (1). The LDI has a white or silver appearance initially, but it will turn red if it is triggered by the presence of liquid, signifying potential water damage to the phone.
Specifically on the iPhone 11 Pro Max, the LDI indicator is located on the top near the earpiece grille. It is a small circular sensor that will change colors if it comes into contact with moisture (2).
The possible colors and what they indicate are:
- White/Silver – No water contact detected
- Amber/Orange – Water contact detected but extent unclear
- Red – Water damage detected
So in summary, the LDI is a liquid contact indicator designed to help determine if an iPhone has been exposed to moisture. Its color provides visual cues as to whether water or liquid damage may have occurred (3).
The LDI Sensor
LDI stands for ‘Liquid Damage Indicator’. It is a sensor that detects exposure to water and other liquids. The LDI sensor is located internally within the iPhone, often near points where moisture could enter such as around battery connectors, SIM card slots, etc. According to Apple, the LDI sensor’s color is normally white or silver, but turns red when it comes into contact with water or a liquid containing water. This sensor allows both Apple and iPhone users to quickly identify if internal water damage has occurred.
Reason for the LDI Indicator
Apple first introduced the Liquid Damage Indicator (LDI) sensor in the iPhone 6 in 2014. The main reason Apple included this sensor is to detect any unauthorized repairs or tampering that could compromise the water resistance of the phone (1).
The LDI is a small sticker located inside the iPhone that will change color if it comes into contact with any moisture. It is designed to turn red or amber if the iPhone casing is opened incorrectly or by an unauthorized third party repair shop. This allows Apple technicians to quickly identify if the water resistance seals have been compromised (2).
By including the LDI, Apple aims to discourage DIY repairs and ensure only Apple authorized technicians open and service the iPhone. This allows Apple to have full control over maintaining the water resistance rating and warranty coverage of their devices.
Green LDI Indicator
A green LDI indicator means the iPhone has not been exposed to liquid or high humidity levels. According to Apple’s support page, “An LCI will activate when it contacts water or a liquid containing water. The indicator’s color is normally white or silver, but when it is triggered it turns red.” [1] So a green LDI indicator signifies that the iPhone is in normal working condition and has not had any exposure to liquids that could cause water damage.
The LDI sensors are very sensitive and designed to detect even small amounts of moisture. A green LDI means there has been no laser exposure or liquid contact that would trigger the sensor. Essentially, green means go – the phone is safe from prior water damage or leakage issues. Users can rest assured that a green LDI reading means the phone is in its factory condition without any liquid exposure history.
Amber/Red LDI Indicator
An amber or red LDI indicates that the phone has been exposed to liquid and likely has water damage. An amber or red color change is triggered when the indicator contacts any liquid containing water. According to Apple’s support page, Water and other liquid damage to iPhone or iPod isn’t covered by warranty, the LDI color changes to reddish-orange or red in the presence of liquid.
An amber or red LDI can also indicate unauthorized repair attempts. Apple states that the LDI senses exposure to moisture during opened-device handling. This means that if a phone is disassembled by anyone other than Apple or an Apple Authorized Service Provider, any exposure to moisture during repair could trigger an amber or red LDI.
Consequences of Tampering
Apple takes a strict stance against unauthorized repairs on iPhones. If the LDI sensor detects that the phone has been opened or tampered with by a non-Apple technician, Apple may refuse to service the device under warranty. According to Apple’s Terms and Conditions, “unauthorized modification of iOS is a violation of the iOS end-user software license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software.”
There have been reports of Apple Geniuses denying service to iPhone users who admitted to getting third-party repairs, even for issues unrelated to the repair. In some cases, Apple has even “bricked” iPhones through software updates when third-party components were detected, rendering the device unusable.
Apple wants customers to only use Apple authorized service providers for repairs in order to maintain their strict quality control standards. However, many consider their policies to be anti-consumer and anti-competitive. The threat of warranty voiding and being denied service has discouraged some iPhone owners from seeking more affordable third-party repair options.
Authorized Service Options
If the LDI indicator on your iPhone 11 Pro Max shows signs of damage, Apple recommends taking it to an Apple Store or Apple authorized service provider for inspection and potential repair. These locations are certified and equipped to service Apple products without tripping the LDI sensor and voiding your warranty.
Over 5000 Apple authorized service providers exist worldwide, providing warranty repairs, out-of-warranty service, and more for iPhones and other Apple devices. You can find a list of Apple authorized service locations on Apple’s website to schedule a repair appointment.
Opting for an Apple authorized service provider rather than a third-party repair shop ensures your iPhone’s LDI sensor will remain intact. Authorized technicians are trained to follow Apple repair procedures and avoid modifications that could tamper with the LDI indicator.
DIY Repair Program
In 2021, Apple announced a new Self Service Repair program that allows customers to complete their own repairs on certain iPhone 12 and 13 models using genuine Apple parts and tools (1). The program launched in the US in early 2022 and expanded to Europe later in the year (2).
The DIY repair program allows replacing components like the display, battery, and camera while still retaining the device’s warranty. Customers can purchase genuine Apple parts and specialized tools through the Apple Self Service Repair online store (3).
This represents a major shift for Apple, who previously restricted repairs to authorized service providers. The goal is to give customers more options when service is needed. However, Apple cautions that self repairs are intended for individuals with technical expertise.

Criticism of LDI Sensors
The use of Liquid Damage Indicator sensors in iPhones and other Apple products has received criticism from consumer advocacy groups and proponents of the “right to repair” movement. Critics argue that the LDI sensors give Apple too much control over repairs and are anti-consumer.
Specifically, if the LDI sensor is triggered, Apple will often refuse to service the phone even for unrelated issues. This forces consumers to go through Apple or Apple-authorized service providers which are typically more expensive. The sensors make it extremely difficult for third party or DIY repairs (Reddit, 2019).
Groups like iFixit and Repair.org advocate for right to repair legislation and note that restricting repairs only benefits Apple’s profits, not consumers. The use of LDI sensors makes phones less repairable and replaceable. Critics argue Apple should not prevent consumers from fixing their own purchased property (Alfano et al., 2020).
The Bottom Line
The Liquid Damage Indicator is an important sensor inside iPhones that detects potential water damage. Its purpose is to protect consumers by discouraging unauthorized repairs that could compromise the phone’s water resistance. An amber or red LDI indicator means Apple may deny service for that iPhone, since water damage cannot be safely repaired by uncertified technicians.
Consumers should think twice before tampering with the LDI or pursuing DIY repairs, which risk permanently damaging your iPhone or voiding the warranty. Instead, go through Apple’s Repair site and Authorized Service Providers to ensure qualified technicians handle any repairs. Water damage is complex and requires Apple’s proprietary tools and methods to fix correctly.
