If your phone shuts down before it hits zero or your laptop barely lasts an hour, the battery has degraded. ZoomFones fits genuine replacement cells for phones, tablets and laptops across Sydney, with most phone batteries done in about 30 minutes. Prices start from $50, with a 6-month warranty on Apple and 12-month warranty on Samsung.

Battery health in settings is a guide, not a verdict. We check the cycle count and actual capacity, because a battery can read 80% healthy and still sag in voltage under load, which is why a phone dies at 40%. We replace when capacity is well below original or the cell is unstable.
Lithium-ion cells degrade unevenly. A worn cell can show a healthy percentage but sag in voltage the moment the phone draws current, such as when you open the camera or use 5G in the cold. The phone's fuel gauge misreads the drop and shuts down to protect itself. A new cell fixes the voltage sag.
We cycle and calibrate the new battery so the percentage readout tracks the real charge. For MacBooks we reset the system management controller so the laptop recognises the new cell and charges it correctly.
"Went in to get a screen protector and ended up getting my cracked screen fixed too. Great service at a fair price, super fast."
"Cracked my screen and another place quoted me way more. Got it replaced under 20 minutes at a third of the price. Looks new now."
"Did an awesome job fixing my phone. Polite, high-quality work, and a great price. Quick and reliable, highly recommended."
"Fast and reliable service, the tech was precise diagnosing the issue and gave an accurate time frame. Would recommend."
"Walked in without an appointment and still got seen the same afternoon. Honest about what actually needed replacing."
"Price matched a quote I got elsewhere without any fuss. The repair itself has held up perfectly months later."
Below 80% capacity is the usual threshold, but if your phone shuts down randomly, gets hot, or the battery is swollen, replace it regardless of the percentage. A swollen battery is a safety issue, so stop using the device and bring it in.
No. Battery replacement does not touch your storage. We do recommend a backup before any repair, but a battery swap alone will not affect your photos, apps or settings.
We use genuine cells where available and OEM-grade cells from certified suppliers otherwise, each with the same warranty. We will tell you which is going into your device before the repair.
macOS flags a battery when its capacity has dropped or it can no longer deliver peak power. We replace the cell and reset the system management controller so the laptop reads the new battery correctly. MacBook battery replacements take 1 to 2 days.
