Apple Watch Series 5 Repair40mm / 44mm · 2019 · First always-on display
🌗 First always-on display Series · 6+ years old · Swollen battery cases very commonSeries 5 was Apple's first Watch with always-on display — a feature that meaningfully accelerated battery wear vs Series 4. At 6+ years old, swollen battery is the dominant service item we see on this model. Most Series 5 batteries we open have visibly expanded cells. ECG sensor degradation is becoming common too. Otherwise these are solid Watches that respond well to component-level repair.

Apple Watch Series 5 — at 6+ years, what we see
Series 5 batteries took a real beating from being the first to power an always-on display continuously. Most are now well below 70% capacity — and a meaningful percentage have swollen physically. Swollen battery cases are by far our #1 Series 5 service item. ECG sensor degradation is the second most common issue. Charging coil corrosion and cracked screens round out the typical Series 5 service list.
⚠️ Swollen battery — fire safety priority
Series 5 swollen battery cases are very common at 6+ years. If your screen is starting to lift off the case, the battery has swollen and is a fire and chemical hazard. Stop wearing the watch and bring it to us within 24 hours for safe removal of the swollen cell. Pricing is R1,200 for battery + safe disposal of swollen cell + new gasket and reseal.
Swollen battery (very common)
By far the #1 Series 5 fault. Always-on display accelerated battery wear. Swollen cells push the screen up — fire safety priority. Stop wearing immediately.
Battery completely worn
6+ years of always-on display. Most batteries below 70% capacity. Won't last past mid-morning. Replacement essential.
ECG sensor failure
Series 5's ECG electrode degrades over time with skin oils and sweat. ECG app fails or returns errors. Back glass replacement with sensor recalibration.
Cracked screen
6 years of accumulated impact damage. Glass-only repair if LCD intact at R1,800, full screen at R2,800.
Charging coil corroded
6 years of sweat exposure = significant charging coil corrosion. Charges slowly, intermittently, or fails. Component-level repair routine at this age.
Crown sweat damage
Years of sweat ingress causes Crown stickiness, ghost scrolling, or unresponsive presses. Deep clean often resolves at lower cost than full replacement.

Apple Watch Series 5 — frequently asked questions
Why are Series 5 swollen battery cases so common?
Series 5 was the first Apple Watch with always-on display — meaning the OLED is drawing current 24 hours a day. This accelerates battery wear significantly compared to Series 4. Combined with 6+ years of age, the cells have undergone many more deep-discharge cycles than they were designed for, and a meaningful percentage swell physically. We see Series 5 swollen batteries multiple times per week.
My Series 5 screen is lifting off — what to do?
Stop wearing it immediately. The battery has swollen and is a fire and chemical hazard. Don't try to push the screen back down. Bring it to us within 24 hours for safe removal of the swollen cell, replacement battery, new gasket, and case reseal. Pricing is R1,200 — no extra charge for swollen battery handling vs standard battery.
My Series 5 ECG stopped working — fixable?
Yes, in most cases. Series 5's ECG electrode degrades over years of skin oil and sweat exposure. If the ECG app shows errors or won't record, back glass replacement with sensor recalibration at R800 typically restores function. Some cases need full replacement — we confirm during diagnostic.
Is Series 5 worth fixing at 6+ years?
Single battery replacement at R1,200 is almost always worth it — especially for swollen battery cases where safety matters even if you don't plan to use the watch heavily. Battery + charging coil at R2,150 is still good value vs R5,000+ replacement. Multiple major faults reaching R2,500+ becomes borderline — we honestly assess economic viability.
Does Series 5 still get watchOS updates?
No — Apple has ended watchOS updates for Series 5. Your watch continues working with the last supported watchOS but won't get new features or security updates going forward. Most apps still work but newer apps may drop Series 5 support over time.
Are Series 5 parts still available?
Yes — we maintain stock of OEM-grade Series 5 parts including batteries, screens, Crown assemblies, and ECG sensor packs. Some specialty parts (premium materials like ceramic) have longer lead times. We confirm parts availability when sending your quote.
Will my Series 5 still be water resistant after repair?
Honest answer: Series 5 seals are 6 years old and any opened Apple Watch has reduced water resistance vs factory new. We use professional cold-press resealing to restore as much as practically possible. Splashes and rain remain fine. We strongly recommend avoiding all swimming, surfing, hot tubs, and steam rooms post-repair.
How long does Series 5 repair take?
Most Series 5 repairs are 24-48 hours. Swollen battery cases need 24-48 hours due to additional safety procedures. Battery and charging coil same-day in Gauteng walk-ins. ECG sensor work 24-48 hours. Nationwide via The Courier Guy with overnight: 3-5 days door-to-door.

Apple Watch Repairs — Frequently Asked Questions
Will my Apple Watch still be water-resistant after repair?
We reseal every Apple Watch using professional cold-press adhesive and allow full cure time — giving you the best possible water resistance a repaired device can achieve. While factory IP ratings cannot be officially recertified post-repair, our resealing process is as close as it gets
Do you use genuine Apple parts?
We use OEM-grade parts that are manufactured to the same specifications as Apple's original components — meaning the same brightness, touch sensitivity, and build quality you expect from your Apple Watch. Where genuine Apple parts are available for your specific model, we will always present that as an option. Either way, you are told exactly what part is being used, the cost, and the warranty before we touch your device. No surprises
Do you repair Apple Watch batteries?
Absolutely — battery replacement is one of the most common Apple Watch repairs we do. If your watch is shutting down before the end of the day, showing a Service Battery warning, or simply not holding a charge like it used to, a new battery will restore it to full performance. We use OEM-grade cells built to Apple's original capacity specs, and most battery replacements are completed the same day. Priced from R900 with a 6-month warranty included.
Can Apple Watch screens be repaired?
Yes — Apple Watch screens can be repaired, and in most cases you do not need a full device replacement. At iAssist we replace the OLED display assembly or front glass depending on your specific model, from the original Series 1 right through to the Series 11 and Ultra 2. All screen repairs use OEM-grade parts, are completed within 24–48 hours, and carry a 6-month warranty
How long does an Apple Watch repair take?
Most Apple Watch screen and battery replacements are completed the same day — often within a few hours of drop-off. For more complex repairs such as water damage treatment or Digital Crown replacement, turnaround is typically 24–48 hours. We will always give you a realistic time estimate upfront before any work begins. If you are not local, we offer a collection and delivery service across Gauteng for R300 — your watch is collected, repaired, and returned to your door
How much does Apple Watch screen repair cost in South Africa?
Apple Watch screen repair in South Africa costs between R1,500 and R3,500 at iAssist, depending on your model. A Series 7, 8, or 9 screen replacement sits toward the higher end due to the larger OLED panel, while earlier models like the SE or Series 4 are more affordable. All pricing is confirmed after a free diagnostic assessment — you receive a written quote before we begin, with no hidden fees. For the most accurate price for your specific model, WhatsApp us with your Apple Watch model and we will come back to you within minutes
Do you repair all Apple Watch models including the Ultra?
Yes — we repair every Apple Watch model ever released, including the Ultra and Ultra 2. From the original Series 1 through to the Series 11, SE 1st and 2nd gen, and both Ultra models, we carry parts and have hands-on experience with each generation. Apple Watch Ultra repairs are frequently declined by other repair centres due to the complexity of the 49mm titanium case — we do not decline them. If you are unsure of your model, WhatsApp us a photo and we will identify it for you instantly
Do you offer collection and delivery for Apple Watch repairs?
Yes — we offer a door-to-door collection and delivery service across the entire Gauteng province for R250. You do not need to travel to our Silvamonte repair centre. We collect your Apple Watch, carry out the repair at our workshop, and return it directly to your door. Collection and delivery is available across Johannesburg, Pretoria, and all surrounding Gauteng areas. Simply WhatsApp us to arrange a collection time that suits you
Is my data safe during an Apple Watch repair?
Completely. Your Apple Watch data, health records, activity history, and paired iPhone connection all remain intact throughout the repair process. We do not factory reset your device unless it is absolutely required for a software repair — and if that is ever the case, we will tell you before we begin, not after. Your watch leaves our workshop exactly as it came in, just fixed
