Apple iPhone SE troubleshooting

Published specification

What is true of this model and changes how you fix it

• Display
  4.7-inch widescreen LCD with IPS technology, 1334-by-750 at 326 ppi.
• Chip
  A15 Bionic.
• Connector
  Lightning.
• Biometric
  Touch ID — a fingerprint reader, not face recognition. Advice about lighting, angles and face coverings does not apply here. What affects this model is moisture and the skin itself changing, and enrolling the same finger twice improves reliability more than repeated attempts against a single reference.
• Camera
  12MP Main camera.
• Storage options
  Sold in 64GB/128GB/256GB.
• Wi-Fi
  Wi-Fi 6 (802.11ax) with 2x2 MIMO.
• Bluetooth
  Bluetooth 5.0.
• Screen brightness
  625 nits maximum brightness (typical).
• Wireless charging
  No MagSafe magnet array on this model.
• Weight
  5.09 ounces (144 grams).
• Panel type
  An LCD panel rather than OLED.
• What owners run into
  Battery drain on a small battery that has aged, touch problems after drops or with protectors, and storage that fills on a base model with no card slot. The home button's Touch ID is also affected by wet or dirty fingers.
• How to approach a fault
  Check Battery Health first, then restart, update iOS and test with the case and protector removed. Back up to iCloud or a computer before any repair.
• Care
  A small phone slips easily, so a case with a lip protects the glass. Keep the Lightning port clean, since lint prevents charging.
• Support
  Apple Support and authorized providers handle battery and screen repairs with the serial number from Settings, General, About.
