The iPhone 11 Pro represents a perfect balance between compactness and advanced functionality. This model was designed for users seeking a premium experience, but like any electronic device, its battery degrades over time. When you notice your iPhone 11 Pro no longer holds a charge like it used to, don't wait — a quality battery replacement can restore its original power. Viper Mobile has been operating at Bulevar Arsenija Čarnojevića 91/3 in New Belgrade for two decades, specializing in iPhone repairs. Our team of experienced technicians works with iPhone 11 Pro models on a daily basis and understands all the specifics of this sophisticated device. The iPhone 11 Pro uses an advanced battery that supports demanding features like ProRAW photography, Dolby Vision video recording, and intensive use of the OLED display. As the battery ages, these processes become more power-hungry than what a weakened battery can deliver. Typical symptoms include sudden shutdowns in cold temperatures, slower app loading, reduced screen brightness, and even camera issues where it can't focus due to insufficient power supply. For the iPhone 11 Pro, we use premium replacement batteries that are not only compatible but often exceed the specifications of the original Apple battery. The price for a premium battery replacement is 6500 RSD, which is a minimal investment for restoring full performance to this expensive device. Our batteries undergo rigorous quality testing and come with safety certifications. After installation, the Battery Health app will show 100%, confirming that the new battery is fully functional. The iPhone 11 Pro requires special attention during servicing due to its complex internal architecture. We use original Apple tools and manufacturer-prescribed procedures. Every step is precisely planned — from carefully opening the housing to calibrating the system after installation. The process takes about one hour, during which you can wait at our service center or come back to pick up your device. We provide a 90-day warranty on all work performed. Contact us at 065/362-61-31 to schedule an appointment or visit our service center directly.
Battery Replacement iPhone 11 Pro
Price List
A quality aftermarket battery at full capacity. On iPhone 12 and newer, Battery Health works normally and the phone reads it as “Used” in Parts & Service History — a pre-owned original, which it is not. No pop-up warnings. 90-day warranty.
Note: if the back cover is cracked, the battery warranty does not apply — a shard of glass can fall inside and puncture the new battery. If we replace the cover during the same visit, the battery keeps its full warranty.
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.
