Samsung Note 5 Water Damage: What to Do

Card No. 06·30084 · Updated · Standard formula, shown below

If your Samsung Galaxy Note 5 fell in water, the immediate answer is: turn it off, dry the outside, and do not charge it or press buttons; then leave it in a dry, airy place for at least 48 hours before attempting to power it on. The Note 5 has no official water resistance rating, so any liquid contact can cause corrosion and short circuits, but quick action can often save the phone.

Background: The Note 5 and Water Resistance

The Samsung Galaxy Note 5, released in August 2015, was a flagship phablet with a 5.7-inch Quad HD Super AMOLED display, an Exynos 7420 processor, and 4GB of RAM. Unlike later Samsung flagships (starting with the Galaxy S7 in 2016), the Note 5 did not come with an IP (Ingress Protection) rating. That means Samsung never tested or certified it against dust or water ingress. In practical terms, the phone has no built-in protection against splashes, rain, or submersion.

The device has a glass back and a metal frame, but the seams around the buttons, SIM tray, speaker grilles, and the charging port are not sealed with the same gaskets used in water-resistant phones. Even a brief drop into a sink or toilet can allow water to reach the internal circuit board.

What Happens Inside When Water Gets In

Water, especially if it contains minerals or impurities, is conductive. When it bridges electrical contacts on the motherboard, it can cause short circuits that may instantly kill the phone or lead to gradual corrosion over days or weeks. The most vulnerable parts are the charging port, the battery connector, the display flex cables, and the logic board itself.

Even if the phone appears to work after drying, residual moisture can cause corrosion on the solder joints and connectors, leading to intermittent failures later. That is why the drying period is critical, not just for the immediate boot but for long-term reliability.

Immediate Steps to Take (Do These Right Away)

  1. Remove the phone from water as quickly as possible. The longer it stays submerged, the more water can seep in.
  2. Turn it off immediately if it is still on. Hold the power button and select “Power off� or force-restart if the screen is unresponsive. Do not try to unlock or check if it works.
  3. Do not press any buttons (volume, home, etc.) because pressing can push water deeper into the internals.
  4. Do not charge it. Charging a wet phone can cause electrolysis and damage the charging IC or battery.
  5. Remove the SIM card tray and any accessories like a case or screen protector. This gives water a path to evaporate.
  6. Wipe the outside with a soft, lint-free cloth. Do not use heat (hair dryer, oven) because it can warp plastic parts and damage the display adhesive.
  7. Dry it in a well-ventilated area. You can place it in front of a fan (not directly blowing into ports) or in a dry room with low humidity.

Common Myths: Rice vs. Silica Gel

You have probably heard that putting your phone in a bag of rice helps. The idea is that rice absorbs moisture. However, rice is not a desiccant; it does absorb some humidity but very slowly and inefficiently. More importantly, rice dust can get into the headphone jack or charging port and cause further issues. Silica gel packets (the kind that come with shoe boxes or electronics) are far more effective because they are made to absorb moisture. If you have a few silica packets, place the phone in a sealed container with them for 48 hours.

Another myth is that using a vacuum cleaner can suck water out. That is risky because the suction can pull water deeper into the phone and static electricity can damage components. Stick to passive drying.

What NOT to Do

  • Do not use a hair dryer or heat gun – heat can melt adhesives and damage the battery.
  • Do not put the phone in the microwave or oven – obvious fire hazard.
  • Do not shake the phone vigorously – you might spread water to areas that were still dry.
  • Do not plug in the charger even if the phone looks dry – wait at least 48 hours.
  • Do not use isopropyl alcohol unless you are opening the phone and know what you are doing – it can damage the oleophobic coating on the screen.

After Drying: How to Test and When to Seek Help

After 48 hours, you can try to power on the phone. If it turns on and functions normally, great, but keep an eye on it for a few days. Watch for signs of corrosion: the charging port may not work, the battery may drain fast, the speaker may sound muffled, or the screen may flicker. If any of these happen, the phone likely needs professional repair.

If the phone does not turn on, do not keep trying to charge it. That can cause more damage. At this point, your best option is a professional repair service. They can open the phone, clean the motherboard with an ultrasonic cleaner, and replace damaged parts. This is often cheaper than buying a new phone, but it depends on the extent of the damage.

Can You Prevent Water Damage?

You cannot make the Note 5 water-resistant, but you can reduce the risk:

  • Use a waterproof case (a sealed pouch or a case with an IP rating) when near water.
  • Avoid using the phone in the bathroom where steam can enter the ports.
  • Keep the phone away from open drinks and sinks.
  • If you drop it in water, act quickly – every second counts.

Frequently Asked Questions

Is the Note 5 water-resistant?

No, the Galaxy Note 5 has no IP rating and is not water-resistant. Samsung only introduced water resistance with the Galaxy S7 and Note 7 (the latter was recalled for battery issues). So any water contact is a risk.

Can I use a wireless charger after the phone dries?

Yes, but only after you are sure the phone is completely dry (at least 48 hours). Wireless charging uses an electromagnetic coil, so it does not rely on the USB port, but if moisture is still inside, it can still cause a short circuit. Wait the full drying period.

How long should I leave the phone in rice?

If you use rice, leave it for at least 48 hours. But silica gel packets are better. Do not check on it every few hours – each time you open the bag, you let moisture back in. Patience is key.

Will the water damage indicator tell me if it’s damaged?

Most Samsung phones have a small white sticker (or dot) inside the SIM slot that turns red when it contacts liquid. You can check it by removing the SIM tray and looking inside. If it’s red, the phone has been exposed to moisture, which may void the warranty (if it were still under warranty, which it is not for a 2015 phone).

Is it worth repairing a water-damaged Note 5?

It depends on the cost of repair versus the value of the phone. A professional cleaning might cost $50–$100, but if the motherboard is fried, the repair could exceed the phone’s used value (which is around $100–$150 as of 2024). Get a quote before committing.

Can I back up data from a water-damaged Note 5?

If the phone still turns on, you can try to back up via Smart Switch or cloud services. If it does not turn on, you may need a professional to recover data from the memory chip, which is expensive and not always successful. That is why regular backups are important.
