⚠️ Important when installing genuine Apple parts

Genuine Apple screens and batteries go through Apple configuration (pairing the part with the device). If a non-genuine part that did not pass configuration was previously installed on your phone, the new genuine part also will not be able to complete the configuration process.

Before installation, with your approval, we check the parts history on the device — because there is no other way to verify it without access to the phone.

iPhone 12 and iPhone 12 Pro Battery Replacement - Professional Service in New Belgrade

Is your iPhone 12 or iPhone 12 Pro draining faster than it used to? Does the phone shut down unexpectedly or show inaccurate battery level readings? These are clear signs that it's time for a battery replacement. At the Viper Mobile service center at Bulevar Arsenija Čarnojevića 91/3, we have specialized in solving exactly these kinds of problems for a full 20 years.

Why the iPhone 12/12 Pro battery fails

The iPhone 12 and iPhone 12 Pro use lithium-ion batteries that naturally lose capacity over time. Apple implemented advanced battery technology in these models, but even that has its own life cycle. An average battery lasts between 500-800 full charge cycles before its capacity drops below 80% of the original. Once that happens, the phone becomes unreliable for everyday use.

Common causes of battery degradation include exposure to extreme temperatures, frequently charging to 100%, using the phone while it charges, and the natural aging of the chemical components inside the battery. With the iPhone 12 series, it's especially important to keep in mind whether the phone uses MagSafe charging, since wireless charging generates more heat, which can speed up the degradation process.

Our battery replacement service

When you bring your iPhone 12 or iPhone 12 Pro to our shop, we first run a detailed diagnostic of the Battery Health function and check the overall condition of the phone. We use exclusively premium replacement batteries from verified suppliers, with a capacity equal to or greater than the original Apple battery. This means that after the replacement you'll have a Battery Health of 100%.

The entire procedure takes about an hour. Our technicians carefully open the phone using specialized tools, taking care not to damage the housing or the internal components. The old battery is safely removed, and the new one is precisely fitted and connected. Before closing the phone, we test all functions, including charging, battery calibration, and a check that all sensors are working properly.

Price and warranty

For the iPhone 12 and iPhone 12 Pro, we offer a premium battery replacement at a price of 6,500 RSD. This price includes a top-quality battery, expert installation, and all the necessary diagnostics. We provide a 90-day warranty on the completed service.

It's worth noting that a quality battery isn't just a short-term fix - it will extend your phone's life for another 2-3 years of normal use. An investment of 6,500 RSD is significantly more affordable than buying a new phone, and the performance will be like that of a new device.

Contact and location

Frequently Asked Questions About Battery Replacement

How do I know if I need a new iPhone battery?

Check Battery Health in Settings → Battery → Battery Health. If it's below 80%, replacement is recommended. Other signs include: phone shutting down at 20-30%, rapid draining, and slow charging.

How long does iPhone battery replacement take?

iPhone battery replacement takes 1 to 3 hours depending on the model.

Will I lose my data during iPhone battery replacement?

No. Battery replacement does not affect your data, photos, apps, or settings on your iPhone. We never erase anything and never ask for your unlock code.

Is the iPhone battery original?

Yes. For iPhone 12 and newer, we use original batteries from the authorized Apple distributor that display 'Genuine Apple' status and Battery Health percentage in settings. For older models, we offer premium high-capacity batteries.

How long does a new iPhone battery last?

An original Apple battery typically retains over 80% capacity during the first 2 years of normal use (approximately 500 charge cycles). Exact lifespan depends on usage patterns.

What is the warranty on an iPhone battery replacement?

Genuine Apple (original) batteries: 6-month warranty. Premium replacement and JCID Enhanced batteries: 90 days (3 months). One exception: if the phone's back cover is cracked at the time of installation, the battery warranty does not apply — a shard of glass can fall inside and puncture the new battery. That is why we suggest replacing the cover during the same visit; the battery then keeps its full warranty. The exception applies to the battery only — all other installed parts keep their regular warranty periods.
