⚠️ 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 Pro Max Battery Replacement - Professional Service at Viper Mobile

The iPhone 12 Pro Max, as the most advanced model in the iPhone 12 series, features the largest battery in that generation of phones. Despite being designed for long-lasting performance, its battery also loses capacity over time. If you notice your phone draining faster or needing more frequent charging, it's time for a professional battery replacement at our shop.

iPhone 12 Pro Max Battery Specifics

The iPhone 12 Pro Max comes with a battery of approximately 3687 mAh, which is significantly more than the standard models in the same series. This larger battery provides up to 20 hours of video playback, making it ideal for heavy phone users. However, precisely because of its size and complexity, replacing this battery requires special care and experience.

With Pro Max models, we frequently encounter specific issues such as unexpected shutdowns at low temperatures, slower charging, or even overheating during use. These symptoms usually indicate that the battery has reached the end of its lifespan and needs to be replaced.

Apple implemented an advanced battery management system in the iPhone 12 Pro Max that optimizes performance based on user habits. When the battery degrades, this system may begin throttling processor performance to prevent unexpected phone shutdowns.

The Replacement Process at Viper Mobile

Our team of technicians with twenty years of experience approaches iPhone 12 Pro Max battery replacement methodically and carefully. The process begins with a thorough diagnostic where we check the current Battery Health, battery capacity, and the overall condition of the phone. This analysis allows us to determine whether the problem is actually the battery or possibly another component.

To open the iPhone 12 Pro Max, we use specialized tools and techniques that leave no marks on the phone's housing. We pay special attention to the cameras and sensors, as this model relies on precise calibration of its Pro features. The old battery is carefully removed, and a new premium battery is installed with full system calibration.

We use exclusively batteries from verified suppliers whose capacity is equal to or greater than the original Apple battery. After installation, Battery Health will show 100%, and the phone will perform like new. The entire procedure takes about one hour, during which you can wait at our shop or come back when it's done.

An Investment That Pays Off

The price of a battery replacement for the iPhone 12 Pro Max is 8000 dinara and includes the premium battery, professional installation, diagnostics, and testing of all phone functions. Considering that the iPhone 12 Pro Max remains a top-tier phone with excellent cameras and performance, this investment will allow you to keep using it for several more years without issues.

We provide a 90-day warranty on the service performed and issue a fiscal receipt. Our warranty covers both the battery quality and the quality of installation, giving you complete confidence in our service.

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.
