iPhone 11 Battery Replacement - New Belgrade

The iPhone 11 is one of the most popular models still used by millions of people around the world. However, after several years of intensive use, the battery on this device starts showing signs of degradation. If you notice that your iPhone 11 is draining faster, charging more slowly, or shutting down unexpectedly, it's time for a battery replacement.

At Viper Mobile, located at Bulevar Arsenija Čarnojevića 91/3 in New Belgrade, we've been specializing in professional iPhone battery replacements since 2004. Our years of experience ensure that your iPhone 11 will work like new again.

Why the iPhone 11 Battery Degrades

The lithium-ion batteries used in the iPhone 11 have a limited number of charge cycles. After 500–800 cycles, battery capacity begins to drop significantly. This manifests as shorter battery life, more frequent charging, and decreased system performance. iOS automatically throttles the processor when it detects an aging battery, resulting in slower app performance.

Our Replacement Service

We exclusively use premium replacement batteries from verified suppliers, with capacity equal to or greater than the original Apple battery. After the replacement, your iPhone 11 will show a Battery Health of 100%, meaning full restoration of its original performance.

The price for a premium battery replacement for the iPhone 11 is 5500 RSD, which is an exceptionally affordable investment in extending the life of your device. With every replacement, we issue a fiscal receipt and provide a 90-day warranty on the work performed.

Replacement Process

The entire procedure takes approximately one hour. Our certified technicians use professional tools and procedures that guarantee the safety of your device. Before starting, we test the current battery condition and explain all the necessary steps to you.

After installing the new battery, we perform thorough testing of all device functions to make sure everything works flawlessly. Your iPhone 11 will once again have a full day of use on a single charge, faster app launches, and a stable connection.

Call us at 065/362-61-31 or visit our shop directly. We work professionally, quickly, and with full understanding of our customers' needs.

Frequently Asked Questions About Battery Replacement

How do I know if I need a new battery?

On iPhone, 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. For Samsung, use the Samsung Members app for battery diagnostics.

How long does battery replacement take?

Battery replacement takes 30 minutes to 1 hour depending on the phone model. Most replacements are completed in about 45 minutes.

Will I lose my data during battery replacement?

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

Is the battery original?

Yes. For iPhone 12 and newer, we use original batteries from the authorized distributor that display 'Genuine Apple' status and Battery Health percentage. For Samsung, we use exclusively original batteries — no copies or generic replacements.

How long does a new battery last?

An original battery typically retains over 80% capacity during the first 2 years of normal use (approximately 500 charge cycles). The exact lifespan depends on usage patterns — charging frequency, ambient temperature, and usage intensity.
