How Water Damage Really Works — What Can Be Saved & What Can’t (IMEND 2026 Guide)

Water damage is one of the most unpredictable and misunderstood types of smartphone failure.

A device can appear functional on the outside while suffering severe internal corrosion that

spreads silently. At IMEND, we have repaired thousands of water-damaged devices, giving us the

expert knowledge needed to explain exactly how water damage works — and what can be saved.

This is the definitive IMEND 2026 water‑damage guide.

————————————————————

1. WATER RESISTANCE IS NOT WATERPROOFING

————————————————————

Modern phones often come with IP67 or IP68 ratings. These ratings protect against:

• Controlled fresh water tests

• Still water

• Short exposure

They do NOT protect against:

• Sea water

• Steam or shower humidity

• Hot water

• Toilet water

• Drinks (tea, coffee, cola, juice)

• Chemical cleaners

• Sweat

• Pressure from drops and frame damage

Water resistance weakens naturally with age, heat exposure, drops, and wear.

————————————————————

2. CORROSION BEGINS WITHIN MINUTES

————————————————————

When liquid enters the device, immediate internal reactions occur:

• Copper tracks oxidise

• Connectors corrode

• Charging system weakens

• Display backlight becomes unstable

• Battery contacts deteriorate

• Micro-components begin to short

A phone may turn on and appear normal, but internal corrosion may already be spreading.

————————————————————

3. TYPES OF LIQUIDS RANKED BY DAMAGE LEVEL

————————————————————

1. Sea Water

   Salt causes instant, aggressive corrosion.

2. Toilet Water

   High mineral and bacteria levels accelerate damage.

3. Sugary Drinks

   Sugar crystallises and burns onto the motherboard.

4. Sweat

   Highly corrosive salts cause long-term damage.

5. Rain & Shower Steam

   Slow but steady internal corrosion.

6. Fresh Water

   Least harmful but still dangerous.

————————————————————

4. WHAT NOT TO DO AFTER WATER DAMAGE

————————————————————

Never do the following:

• Do NOT turn the phone on

• Do NOT charge it

• Do NOT shake the device

• Do NOT put it in rice (rice does nothing)

• Do NOT use a hairdryer (heat damages components)

These actions dramatically increase the chance of permanent failure.

————————————————————

5. WHAT YOU MUST DO IMMEDIATELY

————————————————————

• Turn the phone off

• Do not charge it

• Keep it upright

• Bring it to IMEND as soon as possible

IMEND performs:

• Ultrasonic board cleaning

• Corrosion removal

• Liquid extraction

• Battery replacement if needed

• Board‑level diagnostics

• Component repair or replacement

Early treatment massively increases success rates.

————————————————————

6. WHAT CAN OFTEN BE SAVED

————————————————————

With early intervention, many parts can be repaired or replaced:

• Logic board (in many cases)

• Cameras

• Speakers

• Charging port

• Buttons

• Vibration motor

• Screen (depending on the damage)

————————————————————

7. WHAT USUALLY CANNOT BE SAVED

————————————————————

Certain components are extremely sensitive:

• FaceID sensor modules

• TouchID home button chips

• Backlight IC (if severely corroded)

• Damaged power management IC

• Swollen or overheated batteries

These often require replacement for safety.

FINAL IMEND RECOMMENDATION

————————————————————

Water damage is repairable — but only with the correct procedure and quick action.

If your device has come into contact with liquid, switch it off immediately and bring it to IMEND.

Early treatment can save your phone, your data, and your investment.
