  • How to Check Shorting in Mobile Phones (Guide)

    How to Check Shorting in Mobile Phones (Guide)

    Short circuits are among the most common reasons for mobile phones to turn dead, overheat, restart, drain battery fast, or stop functioning suddenly. Every technician, whether beginner or experienced, must know how to diagnose shorting accurately before attempting any repair.

    A shorted motherboard requires careful handling and systematic testing. If diagnosed incorrectly, it may lead to further component damage. Fortunately, with the right tools and the right approach, finding a short circuit becomes simple and methodical.

    “A technician’s real skill lies not in replacing parts, but in identifying the root cause with precision.”

    This guide explains how to check shorting in mobile phones using two reliable methods:

    1. Continuity testing with a multimeter
    2. Current draw testing with a DC Power Supply (Battery Eliminator / Jhatka Machine)

    It also covers why shorting happens, how tracks work, and early symptoms of a short circuit.

    What Is Shorting in Mobile Phones?

    In simple terms, shorting happens when two electrically separate paths unintentionally touch each other, causing current to flow where it should not.

    ✔ Open Circuit

    • When a track breaks and current cannot flow
    • Example: cracked PCB or broken connection

    ✔ Short Circuit

    • When two separate tracks or components touch
    • Causes excessive current flow
    • Leads to heat, failure, or complete shutdown

    Shorting is one of the most damaging faults on a motherboard.

    Common Reasons for Shorting in Mobile Phones

    Short circuits do not happen randomly. They usually have specific causes:

    1. Water Damage

    The number one cause.
    Moisture creates conductive paths between tracks.

    2. Overheating

    Excessive heat melts solder joints and causes bridging.

    3. Using Faulty or Non-Compatible Chargers

    Cheap or fake chargers cause voltage spikes and component burns.

    4. Electrical Shock or Sparks Inside the Motherboard

    Can occur due to damaged components or loose connections.

    5. Physical Damage

    Drops or bends deform internal layers of the PCB.

    6. Manufacturing Defects

    Though rare, improper soldering from factory can cause short circuits later.

    Symptoms of a Shorted Motherboard

    Before testing the phone, technicians should look for signs:

    ✔ Phone completely dead

    ✔ No charging indication

    ✔ Phone heats up without powering on

    ✔ Auto-restart or shutdown

    ✔ Battery draining unusually fast

    ✔ DC Power Supply showing high current draw

    ✔ Burning smell or spark from inside

    ✔ Fast heating of a particular component

    These symptoms help narrow down the diagnosis.

    Understanding Tracks on a Mobile Motherboard

    Phones do not use wires internally. Instead, they use microscopic tracks on the PCB.

    Tracks carry different types of signals:

    • VBAT Tracks → Battery voltage
    • GND Tracks → Ground
    • RX/TX Tracks → Communication
    • I2C/SPI Tracks → Control signals
    • LDO Lines → Regulated power lines

    A short circuit happens when VBAT touches GND or any other unintended line.

    ⚠️ Very Important Safety Warning Before Testing

    Since this article is technician-level:

    • Do NOT use DC Power Supply without training
    • Do NOT touch exposed components during power tests
    • Always remove the battery before board testing
    • Avoid testing on a wet or unclean board
    • Wear anti-static protection when possible

    “A moment of care saves hours of repair.”

    METHOD 1: How to Check Shorting With a Multimeter (Continuity / Diode Mode)

    This is the fastest and safest method.

    Step 1: Set Multimeter Correctly

    • On digital multimeter → Continuity Mode / Diode Mode
    • On analog multimeter → Ohms (×10) Mode

    In diode mode:

    • A beep sound = electrical connection
    • No beep = open circuit

    Step 2: Identify Battery Connector Pins

    Most phone batteries have these pins:

    • VBAT (+) → Battery positive
    • GND (–) → Battery negative
    • BSI / ID → Battery status communication pin
    • BTEMP → Temperature sensor pin (varies by model)

    For shorting test, we focus on:

    • VBAT
    • GND

    Step 3: Position the Probes Correctly

    For multimeter short testing:

    ✔ Touch RED probe (+) to GND

    ✔ Touch BLACK probe (–) to VBAT

    Why this reverse connection?
    It creates a safe current path for testing without damaging components.

    Step 4: Read the Multimeter Response

    Case 1: Continuous Beep / Reading Shows Values

    This confirms:

    ➡ The motherboard is short.

    Case 2: No Beep / No Reading

    This confirms:

    ➡ The board is NOT short.

    Understanding Readings in Diode Mode

    If you test both ways:

    • If readings appear both times → Short circuit confirmed
    • If reading appears only once → Normal behavior

    Some motherboards may show numeric values (e.g., 254, 302, 1000).
    If values appear in both directions = shorting.

    Extra Checks With Multimeter

    ✔ Check heat

    Touch the board lightly to see if any component heats up during tests.
    (This should be done quickly and carefully.)

    ✔ Check for ground short near connectors

    Test charging IC, backlight section, power IC, audio IC, etc.

    METHOD 2: How to Check Shorting Using DC Power Supply (Jhatka Machine)

    This method is more advanced and must be done only by trained technicians.

    DC Power Supply is also called:

    • Battery Eliminator
    • Jhatka Machine
    • DC Regulator

    It supplies stable DC voltage for motherboard testing. Use a high quality, high precision DC Power Supply of 5 Amperes

    Step 1: Set Correct Voltage

    • Most mobile batteries operate at 3.7V – 4.4V
    • Set DC Supply to 4.0V for safe testing

    Never test above safe voltage levels.

    Step 2: Connect the Probes

    • Red Clip → VBAT Pin
    • Black Clip → GND Pin

    Do NOT touch other components during testing.

    Step 3: Read the Current Draw

    The current reading tells you a lot.

    Scenario 1: Current jumps instantly (0.5A – 2A)

    ➡ Short circuit confirmed.

    This means the power line is connected to ground.

    Scenario 2: Current remains at 0.00A

    ➡ No shorting.

    Scenario 3: Current slowly rises even without pressing power key

    ➡ Half short or leakage.
    This requires component-level diagnosis.

    Step 4: Identify Heating Component

    The fastest way to find a shorted component is:

    • Drop a little coolant spray
    • Apply DC Power again
    • See which area melts first (that’s the faulty part)

    Or use:

    • Thermal camera
    • Alcohol method (evaporates quickly at heating spot)

    Common Components That May Short

    • Power IC (PMIC)
    • Charging IC
    • Backlight IC
    • Audio IC
    • CPU caps
    • RAM/CPU solder joints
    • WIFI/Network IC
    • Filter capacitors (most common)
    • Diodes and coils

    90% of short circuits happen because of a single capacitor failure.

    Fixing Shorting in Mobile Phones

    After identifying the short, the repair steps include:

    ✔ Removing shorted capacitors

    ✔ Replacing faulty ICs

    ✔ Cleaning corrosion from water damage

    ✔ Reworking solder joints

    ✔ Checking line voltage again after removal

    Technicians must ensure the short is completely cleared before applying battery.

    Preventing Short Circuits in Mobile Phones

    Your customers can prevent shorting by:

    • Avoiding cheap chargers
    • Keeping phones away from water
    • Not using the phone while charging
    • Avoiding extreme heat
    • Using protective back covers
    • Getting phones serviced after water exposure

    “Prevention costs nothing—repairs cost time, money, and sometimes trust.”

    Conclusion

    Short circuits are one of the most serious faults in mobile phones. But with the right tools, techniques, and a systematic approach, diagnosing shorting becomes straightforward and safe.

    Technicians must always begin any dead phone repair by checking for shorting, because a shorted board cannot boot, charge, or function normally until the short is removed.

    Learning to test shorting using a multimeter and DC power supply gives you a strong foundation in mobile hardware repair, helping you diagnose faults confidently and accurately.

  • How to Fix a Wet Cell Phone Step by Step (Water Damage Repair)

    How to Fix a Wet Cell Phone Step by Step (Water Damage Repair)

    Dropping a cell phone in water is one of the most stressful moments for any user. Whether it slips into a sink, falls into a bucket, gets soaked in rain, or lands in a toilet, the panic is real. Smartphones are expensive, personal, and deeply connected to daily life.

    The good news is this: a wet cell phone does not always mean a dead phone. Many water-damaged devices can be saved if the right steps are taken quickly and correctly.

    This guide explains how to fix a wet cell phone step by step, using practical, technician-approved methods. It covers what to do immediately, what to avoid, and when professional repair is the best option.

    “In water damage cases, speed and the right actions matter more than luck.”

    Understanding What Water Does to a Smartphone

    Before jumping into repair steps, it helps to understand what actually happens when a phone gets wet.

    Water itself is not the biggest enemy. The real damage comes from:

    • Electrical short circuits
    • Corrosion on internal components
    • Mineral deposits left behind after drying

    When a powered device meets moisture, current flows where it should not. This can damage chips, connectors, and the motherboard.

    That is why the first few minutes after water exposure are critical.

    Step 1: Remove the Phone From Water Immediately

    This step sounds obvious, but hesitation can be costly.

    • Take the mobile phone out of water as fast as possible
    • Do not press any buttons while removing it
    • Do not check if it is still working

    Every second the device stays powered and wet increases the risk of permanent damage.

    Step 2: Power Off the Device Right Away

    If the phone is still on, turn it off immediately.

    • Hold the power button and switch it off
    • Do not restart or unlock it
    • Do not check notifications

    Keeping a wet phone powered on is the biggest mistake users make.

    If the phone turns off by itself, do not try to turn it back on.

    Step 3: Remove All External Parts

    Next, strip the device down as much as possible without tools.

    Remove:

    • SIM card
    • Memory card
    • Phone case
    • Accessories like earphones or charging cables

    These parts can trap moisture and slow down drying.

    Place the SIM card and memory card separately on a dry cloth.

    Step 4: Gently Dry the Outside

    Use a soft, lint-free cloth to gently wipe the phone.

    • Pat dry the screen, back, and sides
    • Shake gently to remove water from ports
    • Keep charging port and speaker openings facing downward

    Do not use force. Do not insert anything into ports.

    This step only removes surface water. Internal moisture still remains.

    Step 5: Do NOT Do These Common Mistakes

    Many well-known “home remedies” actually make water damage worse.

    Avoid the following:

    • ❌ Using a hair dryer or heat gun
    • ❌ Placing the phone on a heater
    • ❌ Microwaving the phone (extremely dangerous)
    • ❌ Charging the phone to “check if it works”

    Heat can:

    • Warp internal components
    • Push moisture deeper inside
    • Damage battery cells

    “Heat dries water fast—but it destroys electronics even faster.”

    Step 6: Use Controlled Air Drying

    The safest drying method is time and airflow, not heat.

    What you can do:

    • Place the phone on a dry towel
    • Keep it in a well-ventilated room
    • Use a fan at a distance to improve air circulation

    Position the device so that:

    • Charging port faces downward
    • Speaker grills are not blocked

    Leave it undisturbed.

    Step 7: Silica Gel vs Rice – What Actually Works?

    The Truth About Rice

    Some people keep their phone submerged in unccoked rice for a few hours. Rice absorbs moisture slowly and unevenly. It can also leave dust and starch particles inside ports.

    Rice is better than nothing, but not ideal.

    Silica Gel (Much Better Option)

    Silica gel packets:

    • Absorb moisture efficiently
    • Do not leave residue
    • Are used in professional drying environments

    If available:

    • Place the phone in a sealed container
    • Add silica gel packets around it
    • Leave for at least 24–48 hours
    rice method for fixing wet cell phone

    Silica gel is safer and more effective than rice. However this will work only if the wetness is little and at the start of the holes/gaps.

    Step 8: Wait Long Enough Before Powering On

    Patience is critical.

    Recommended waiting time:

    • Minimum: 24 hours
    • Safer range: 48 hours or more

    Do not rush this step. Moisture trapped under chips and connectors takes time to evaporate.

    Turning on the phone too early can permanently short the motherboard.

    Step 9: Power On and Observe Carefully

    After sufficient drying time:

    • Power on the device
    • Do not plug in the charger yet
    • Check basic functions

    Test:

    • Screen display
    • Touch response
    • Speaker sound
    • Microphone
    • Camera

    If the phone does not turn on, do not panic. This does not always mean it is dead.

    Step 10: If the Phone Turns On but Shows Problems

    Common post-water-damage issues include:

    • No sound
    • Charging problems
    • Foggy camera lens
    • Random shutdowns

    These issues often indicate:

    • Residual moisture
    • Corrosion starting on connectors

    At this stage, professional cleaning is recommended.

    When to Take the Phone to a Repair Technician

    You should visit a repair professional if:

    • The phone does not power on after drying
    • The phone heats up abnormally
    • Charging is unstable
    • Display flickers or touch fails

    Technicians use:

    • Isopropyl alcohol cleaning
    • Ultrasonic cleaners
    • Board-level inspection

    Early professional intervention can prevent long-term corrosion.

    Water-Resistant vs Waterproof Phones: Know the Difference

    Many smartphones are advertised as water-resistant.

    Important points:

    • Water resistance is not permanent
    • Seals degrade over time
    • Drops, repairs, or wear reduce protection

    Water-resistant does not mean water-proof.
    Damage can still occur, especially in saltwater or dirty water.

    Saltwater and Dirty Water: Extra Risk

    If the phone fell into:

    • Sea water
    • Pool water
    • Muddy or dirty water

    The risk is higher due to:

    • Salt corrosion
    • Chemical residue
    • Mineral deposits

    In such cases, professional cleaning is strongly advised, even if the phone seems fine.

    Battery Safety After Water Damage

    Lithium-ion batteries are sensitive to moisture.

    Warning signs:

    • Phone gets hot
    • Battery drains fast
    • Swelling or bulging

    If any of these occur:

    • Stop using the phone
    • Do not charge it
    • Seek professional help

    Battery failure can be dangerous if ignored.

    Data Recovery From a Water-Damaged Phone

    Even if the phone does not fully recover:

    • Data may still be retrievable
    • Storage chips often survive

    Technicians can:

    • Access internal memory
    • Recover photos, videos, and documents

    This is another reason not to attempt risky DIY fixes.

    Can You Fix Water Damage at Home Completely?

    Minor water exposure can sometimes be handled at home if:

    • The phone was powered off quickly
    • Drying was done correctly
    • No corrosion started

    However, deep water damage often requires professional tools.

    Home methods reduce risk—but they do not replace proper cleaning.

    Preventing Water Damage in the Future

    Simple habits reduce risk:

    • Use waterproof cases near water
    • Avoid using phones in bathrooms
    • Keep devices away from kitchen sinks
    • Do not charge phones near liquids

    Prevention is always cheaper than repair.

    Technician-Level Insight: Why Some Phones Die Later

    Some phones work fine after drying, then fail weeks later.

    Reason:

    • Hidden corrosion slowly eats circuit paths

    This is why technicians recommend internal cleaning, not just drying.

    “Water damage is not always immediate. Sometimes it waits.”

    Repair or Replace: Making the Right Decision

    Consider replacing the phone if:

    • Motherboard damage is severe
    • Repair cost is too high
    • The phone is very old

    Repair makes sense if:

    • Damage is caught early
    • Device value is high
    • Data is important

    A technician can help evaluate honestly.

    Frequently Asked Questions (FAQs)

    1. Can a wet cell phone be repaired completely?

    Yes. Many wet cell phones can be repaired if they are powered off quickly and dried properly. Early professional cleaning greatly improves success.

    2. How long should I wait before turning on a water-damaged phone?

    If you are not giving the handset for repairs. you should wait at least 24–48 hours after proper drying. Turning it on too early can cause permanent internal damage.

    3. Does putting a wet phone in rice really work?

    No. Rice can absorb very little moisture, but it is not very effective. Silica gel packets work better but only if the water is minimum and at the border only.

    4. Can water damage affect a phone later even if it works now?

    Yes. Corrosion can develop slowly and cause problems days or weeks later if the phone is not cleaned internally.

    5. Should I repair or replace a water-damaged smartphone?

    Repair is worth it if the phone is newer or data is important. Replacement may be better if repair costs are high or damage is severe.

    A wet cell phone is not automatically a lost cause. Quick action, correct steps, and patience can save many water-damaged smartphones.

    The most important rules to remember:

    • Power off immediately
    • Avoid heat and charging
    • Allow proper drying time
    • Seek professional help when needed

    Smart handling can mean the difference between recovery and permanent failure.
