Time For A New Battery?

Your iPhone is telling you.

iPhone batteries lose capacity after about 500 charge cycles — usually 18–24 months. Here’s how to tell yours is done.

📉

Dies before lunch

Phone was unplugged at 7am, dead by noon. A healthy iPhone gets 12+ hours of normal use. Anything less means battery degradation.

⚠️

“Service” warning in Settings

Settings → Battery → Battery Health shows “Service” instead of “Maximum Capacity %”. iOS is officially flagging your battery as worn.

🔻

Capacity below 80%

Battery Health screen shows below 80%. Apple themselves recommend replacement at this threshold. Performance throttling kicks in.

🥵

Hot to the touch

Phone heats up during normal use, charging, or even sitting idle? That’s a degraded battery working harder than it should.

⏏️

Random shutdowns

Phone shuts off at 30%, 40%, even 50% — then turns back on once plugged in. The battery can’t hold voltage under load anymore.

📱

Bulging or swollen back

Back glass lifting, screen popping out, phone wobbling on the table? Swollen battery — stop using it and bring it in immediately.

$79 Flat · Every Model

Same price. Same warranty. Same battery quality.

We keep the math simple. iPhone 11? $79. iPhone 17 Pro Max? Also $79. Why? Because the battery itself isn’t dramatically more expensive across models — Apple just charges more because they can.

Common Questions

iPhone battery replacement, answered.

Is it really $79 flat for every iPhone model?
Yes — every iPhone model from iPhone 11 through iPhone 17 Pro Max is $79 flat. The actual lithium-ion cell costs roughly the same to source across models. Apple charges $99-$129 with model-based pricing because they can. We don’t.
How long does iPhone battery replacement take?
Most iPhone battery replacements take 30 minutes from walk-in to walk-out. Newer Pro Max models may take 45 minutes due to additional internal sealing. We test the new battery before you leave to confirm 100% Battery Health reading in iOS.
Will my iPhone show 100% Battery Health after the replacement?
Yes — when we install a fresh OEM-grade battery, your Battery Health screen (Settings → Battery → Battery Health) resets to 100% Maximum Capacity and “Peak Performance Capability” goes back to normal. Cycle count starts over at 0.
Will I lose my data when you replace the battery?
No. Battery replacement is a hardware swap — your iPhone’s storage chip is untouched. Photos, apps, messages, settings all stay exactly as they were. We always recommend backing up to iCloud before any repair, but data loss from a battery swap would be extremely unusual.
My iPhone has a swollen battery — is that dangerous?
Yes, swollen iPhone batteries are a real fire risk. Lithium-ion batteries swell when they fail internally, which puts pressure on the screen and chassis. Stop charging it immediately, don’t puncture the battery, and bring it in. We handle swollen batteries safely every week — it’s still $79 flat.
Do you use genuine Apple batteries?
We use OEM-grade aftermarket batteries that match Apple’s specs (capacity, voltage, lithium-ion chemistry). They’re not technically “Apple-branded” since Apple doesn’t sell parts to independent shops — but they’re manufactured to the same standards by the same supplier networks. iOS Battery Health reports them at 100% on day one.
My iPhone shutdowns randomly — is the battery the cause?
Most likely yes. Random shutdowns at 30-50% battery are a textbook sign of a degraded battery that can’t hold voltage under load anymore. Battery replacement fixes this in 95%+ of cases. If it doesn’t, we offer a free post-repair diagnostic to identify other causes (board-level issues, charging IC failure).
Combien coûte le remplacement de batterie iPhone?
$79 pour tous les modèles iPhone, du 11 au 17 Pro Max. Aucun frais caché. Service le jour même aux trois emplacements (Laval, Montréal, Vaudreuil-Dorion). Garantie de 30 jours incluse. Prenez rendez-vous ou venez sans rendez-vous — la plupart des réparations sont complétées en 30 minutes.
