Battery degradation is the silent performance killer. Most people don't realise that an iPhone or Samsung with a battery health below 80% isn't just dying faster — iOS and Android actively reduce CPU performance to prevent unexpected shutdowns, making the entire phone feel slower. A fresh battery doesn't just extend your battery life; it restores the performance you had on day one. At Cybrix Electronics, battery replacement is one of our highest-volume services, and we've perfected the process for virtually every phone, tablet, and laptop on the market.
We use genuine-capacity battery cells that meet the original manufacturer's mAh specifications. Cheap aftermarket batteries with inflated capacity claims are a false economy — they degrade faster, can swell, and in worst cases pose safety risks. Our batteries come with proper safety certifications and are calibrated post-installation so your device reports battery health accurately in its settings. For iPhones, we ensure the Battery Health screen in Settings shows correctly. For Samsung devices, we verify adaptive charging behaviour functions as expected.
Book a battery replacement and we'll have your device ready in 30–60 minutes for most phone models. Laptop batteries take slightly longer but are still commonly done in a single visit. Bring your device in, grab a coffee nearby, and come back to a device that holds a full charge again.
From everyday wear to complex hardware faults — here are the issues we deal with most often.
Your device used to last all day but now barely makes it to lunchtime. This is the most common sign of battery degradation — replacement restores full battery life.
Phone dying at 20%, 30%, or even 50% charge and then starting again when plugged in. A failing battery can't deliver the current spikes needed for demanding tasks.
Apple throttles CPU performance to prevent shutdowns on degraded batteries. Replacing the battery removes the throttling and restores original speed.
A battery that gets very hot during charging is chemically compromised and should be replaced. Continued use risks further degradation or, in severe cases, swelling.
A visibly puffed-up battery (screen lifting, back cover bulging) is a safety issue that needs immediate attention. Swollen batteries can rupture and should not be used.
If your device takes 4+ hours to charge to 100% and the charger and cable check out fine, the battery's internal resistance has increased and it needs replacement.
iPhone reports battery health under 80% in Settings > Battery. This is the threshold at which Apple recommends replacement and enables performance throttling.
Sudden screen dimming under load is often the battery struggling to supply consistent voltage — a sign of significant degradation or a faulty cell.
We carry parts and have experience with the following models — and many more not listed here.
From booking to pickup — a straightforward, transparent process every time.
Select battery replacement and enter your device model. We'll confirm whether we have your battery in stock for a same-visit repair.
On arrival we measure your current battery capacity accurately — not just the phone's reported health percentage, but the actual remaining charge cycle capacity.
We confirm the replacement battery specs, quote the price, and start only when you approve. For phone batteries, the whole process takes 30–45 minutes.
Your old battery is carefully removed and the replacement cell installed. For phone batteries bonded with adhesive, we use proper tools to avoid display damage.
After installation we calibrate the battery — running it through a charge cycle and confirming health reporting in your device's settings before you collect.
