What the free diagnostic includes
-
📊 Battery Health Report
We measure your battery's true capacity with professional equipment — not just the estimate in Settings, which can drift from reality by a surprising margin. You'll see exactly how much real battery you have left.
-
🔁 Cycle Count Evaluation
Every battery has a lifespan measured in charge cycles. We pull your actual count and tell you where your battery sits on its aging curve — plenty of life left, or on borrowed time.
-
📅 Manufacture Date Confirmation
We verify when your battery was actually made. This catches old stock, phones that sat in warehouses, and — if you bought the phone used — batteries that were swapped with aged or low-quality parts.
-
🔍 Physical Inspection
We check for swelling, seal integrity, and connector condition. A battery that's starting to expand can push against the screen and back glass — something no software readout will ever tell you.
-
⚡ Charging Behavior Test
We watch how the battery takes and holds a charge under load — catching the batteries that read "fine" but die at 30% in the real world.
-
🤝 An Honest Verdict
If your battery is healthy, we'll tell you and you walk out free of charge. If it's not, you'll get the exact replacement price for your model — your call, zero pressure.
What wears an iPhone battery out (and what makes it swell)
- 🔥 Heat — the #1 battery killer. Dashboards, sunny windowsills, and charging under a pillow age a battery years ahead of schedule.
- 🥶 Cold exposure — deep cold temporarily cripples capacity and repeated freeze-warm cycles stress the cells.
- ⛰️ Elevation & pressure changes — frequent flying, mountain trips, and big altitude swings put mechanical stress on the sealed cell and can encourage expansion in an already-weak battery.
- ⚡ Cheap or excessive fast charging — bargain-bin fast chargers with sloppy voltage regulation cook batteries. Fast charging is fine; low-quality bricks and cables are not.
- 🌙 Charging habits — living at 100% overnight every night, or regularly draining to zero, both accelerate wear.
- ⏳ Plain old age — lithium cells degrade chemically even with perfect care. After a few hundred cycles, capacity loss is normal physics, not neglect.

How it works

Free battery diagnostic FAQs
Is it really free? What's the catch?
Really free, no catch, no purchase required. It costs us a few minutes and it earns us trust — most people whose battery fails the test choose to replace it with us, and the ones whose battery passes come back when something actually breaks.
Isn't the Battery Health number in Settings enough?
It's a decent starting point, but it's an estimate — it drifts from true measured capacity, it says nothing about swelling, and it can read "normal" on a battery that shuts the phone down at 30%. We measure the real numbers.
What's a battery cycle count and why does it matter?
One cycle = one full charge worth of use. iPhone batteries are designed to hold about 80% capacity through roughly 500 cycles. Your count tells you where you are on that curve — it's the battery's odometer.
Why does the manufacture date matter?
Lithium batteries age chemically from the day they're made, even sitting unused. A "new" battery that's three years old isn't new. The date check also reveals if a used phone you bought has had its battery swapped with old or non-genuine stock.
How do I know if my iPhone battery is swollen?
Screen lifting at the edges, a bulging back, gaps in the frame seam, or a phone that rocks when laid flat. If you see any of these: stop charging it and come in the same day — swelling only goes one direction.
Is fast charging bad for my iPhone battery?
Quality fast chargers are fine — iPhones manage the charge curve carefully. The damage comes from cheap no-name bricks and cables with poor voltage regulation, and from constant heat during charging. If in doubt, bring your charger to the diagnostic and we'll take a look at that too.
At what point should I actually replace the battery?
Below 80% health, past ~500 cycles, any swelling, or real-world symptoms like random shutdowns and midday deaths. The diagnostic weighs all four and gives you a straight recommendation.
