Phone Care & Repair Tips

First: Assess the Damage

Not all cracked screens are equal. There is a big difference between a small corner chip that does not affect touch or display quality, and a screen that is shattered with the display flickering or showing dead zones. Understanding your damage level helps you decide urgency and approach.

• Minor crack or chip: If touch still works and the display is clear, you can wait — but apply a screen protector immediately to prevent the crack from spreading and to protect your fingers from glass shards.
• Cracks affecting display quality: Colour bleed, black spots, or lines through the screen mean the LCD or AMOLED panel itself is damaged — not just the glass. This needs urgent repair.
• Shattered glass with sharp edges: This becomes a safety issue. Tiny glass shards can cut your fingers. Get it fixed quickly.
• Touch no longer responding: If you cannot interact with the phone, it is effectively unusable. Immediate repair is the only option short of replacement.

The Repair Cost vs Phone Value Calculation

The golden rule is simple: if the repair cost is less than 30 to 40 percent of what it would cost to replace your phone with a similar model, repair is almost always the better financial decision. In South Africa, screen replacements typically range from R350 for budget Android models up to R3,500 for high-end iPhones and Samsung flagships.

When Replacing Makes More Sense

There are situations where buying a new phone is actually the smarter call. If your phone is more than 4 to 5 years old and running slowly on outdated software, a screen repair just prolongs the inevitable. If the phone has multiple problems — a bad battery, a damaged charging port, and now a cracked screen — the combined repair cost might exceed the phone's worth.

Why Professional Repair Is Worth It

You will find cheap screen replacement kits on Takealot and YouTube tutorials for DIY fixes. Screen replacement on modern smartphones is genuinely difficult though. The screens on Samsung Galaxy and iPhones are glued with industrial adhesive and require specialised heat tools to remove safely. Getting it wrong risks damaging the fingerprint sensor, the proximity sensor, or water-resistance sealing. A botched DIY repair can turn an R800 repair into an R3,000 problem.

How to Prevent Screen Cracks

Always use a tempered glass screen protector — these absorb impact energy before it reaches the actual display. A good quality phone case that raises slightly above the screen face so the screen does not make direct contact with a surface when dropped face-down is your second line of defence. Together, these two things prevent the vast majority of screen damage we see in our store every week.

Step 1 — Remove It From the Water Immediately

Every second counts. The longer the phone is submerged, the deeper water penetrates through every seal, port, and gap. Even IP68-rated waterproof phones can be damaged by salt water, pool chlorine water, or pressure from depths beyond their rating.

Step 2 — Power It Off Right Away

If your phone is still on, turn it off immediately. Do not try to use it, take photos, or check if it still works. Water and electricity together cause short circuits, and running current through wet components dramatically increases the damage. If you can safely remove the battery on older phones, do so.

Step 3 — Remove Everything You Can

Take out the SIM card, SIM tray, and if applicable, the memory card. Shake the phone gently to remove visible water droplets from the ports. Pat the outside dry with a clean cloth or paper towel. Do not push fabric into the ports as this can push water further inside.

Step 4 — What NOT to Do

• Do not use a hair dryer — direct heat pushes steam further into the phone and can melt internal components and warp screen adhesive.
• Do not put it in rice — the rice trick is a myth that has been thoroughly debunked. Rice is too slow and does not effectively dry internal components.
• Do not charge it — plugging in a wet phone can cause an immediate short circuit, permanently frying the charging circuit or main board.
• Do not try to turn it on to test if it still works — this is how most water-damaged phones become permanently dead phones.

Step 5 — What Actually Works

Leave the phone in a warm, dry environment with good air circulation — not in direct sunlight. Position it with ports facing down to allow water to drain by gravity. If you have silica gel packets (the little sachets that come in shoe boxes), place the phone in a sealed container with several of them. Silica gel actually does absorb moisture effectively. Leave it for at least 24 to 48 hours before attempting to power on.

Step 6 — Bring It to Us for Ultrasonic Cleaning

Even if your phone seems to recover on its own, invisible corrosion may be forming on the motherboard. This corrosion builds over weeks and can cause failures long after the incident — making it look like an unrelated fault. Our professional ultrasonic cleaning process removes water residue and corrosion from internal components safely and thoroughly. We also assess which components, if any, were damaged and need replacement.

A Note on IP Ratings

Many modern smartphones advertise IP67 or IP68 water resistance. The IP rating is tested under laboratory conditions with fresh water. Sea water, pool water, and soapy water are all more corrosive and can defeat the seals. IP ratings also degrade over time as seals age — a two-year-old phone's water resistance may be a fraction of what it was when new. Do not rely on an IP rating as an excuse to be careless near water.

Warning Signs of a Failing Charging Port

• The cable has to be held at a specific angle to charge — this is the number one sign of a worn or bent charging port. If you have found the sweet spot where your cable only charges when angled just right, your port is damaged.
• Intermittent charging — the charging indicator appears and disappears, or your phone charges for a few minutes and then stops. This suggests poor electrical contact between the cable and the port.
• Charging is much slower than it used to be — if your phone used to fast-charge in 1 hour and now takes 3 to 4 hours with the same cable and charger, the port may have dirty or corroded contacts reducing power transfer.
• The cable feels loose in the port — charging ports have small metal tabs inside that grip the cable. These wear down with repeated use over time.
• The phone does not charge at all — this could be the port, the battery, or in rare cases the charging IC chip on the motherboard. A technician needs to diagnose which one.

First: Eliminate the Simple Causes

Before assuming the port is faulty, rule out the easy stuff. Try a different charging cable — cables fail far more often than ports do, and the symptoms are identical. Try a different charger as well. Clean the port gently with a dry toothpick or soft brush (never metal) to remove lint, which commonly builds up and prevents the cable from seating fully. Cape Town dust and pocket lint are real factors here.

When It Is Definitely the Port

If you have tried multiple cables and chargers, cleaned the port, and the problem persists — the port itself needs attention. In most Android phones, the charging port is a separate component (a small circuit board) that can be replaced cleanly without touching the main motherboard. This is a relatively straightforward repair that takes 1 to 2 hours and is typically affordable. iPhone charging ports are more complex, as the port is directly connected to the bottom flex cable which also includes the microphone and speaker wiring. It is still very much repairable — it just requires more precision and time.

How to Extend the Life of Your Charging Port

• Insert and remove the cable gently, without forcing or wiggling it.
• Use a port dust cover or phone case with port protection when not charging.
• Avoid charging while using the phone heavily — placing the phone flat on a surface while it charges removes leverage on the port connector.
• Consider switching to wireless charging to reduce how often you use the port physically.

The Battery Health Concept

Every lithium-ion battery has a finite number of charge cycles before its capacity degrades. A cycle is defined as using and recharging 100% of capacity — so two 50% charges equal one cycle. Most smartphone batteries are rated for 300 to 500 full cycles before noticeable degradation, and 500 to 800 before significant capacity loss. The average user goes through about 300 cycles per year, meaning after 2 to 3 years of use, most batteries have lost meaningful capacity.

Signs Your Battery Is Failing

• Rapid drain — the phone goes from 100% to dead much faster than it used to, even with similar usage patterns.
• Unexpected shutdowns — the phone powers off when the battery indicator still shows 15 to 30%. This is a classic symptom of a battery that can no longer accurately hold charge.
• Swelling — if your phone's back panel is bulging, or the screen appears to be lifting away from the body, the battery has swollen due to internal gas buildup. This is a safety concern. A swollen battery should not be used — bring it in immediately.
• The phone gets very hot while charging or in use — more heat than usual is often a sign of battery degradation.
• Percentage jumps — the battery percentage drops 10% instantly, then later seems to recover. This indicates the battery can no longer accurately measure its own charge state.

How to Check Battery Health Yourself

On iPhone, go to Settings, Battery, Battery Health and Charging. Apple shows you a percentage — anything below 80% is considered degraded and eligible for a battery service. On Samsung devices running Android 12 or later, go to Settings, Battery and Device Care, Battery, Battery Information for health status. Third-party apps like AccuBattery can also track your battery health over time on Android devices.

Battery Replacement vs New Phone — The Maths

A battery replacement at our store costs between R350 and R900 depending on your phone model. A new mid-range Android phone in South Africa currently costs R3,000 to R5,000. If your phone is otherwise working well, a battery replacement extends its useful life by 2 to 3 years at a fraction of the cost of a new device. You also keep your existing apps, data, and settings without needing to set everything up from scratch.
