Here’s a comprehensive review of this product: Pros: Increased Battery Capacity: With a 3800mAh capacity, this battery offers a significant upgrade over the original battery, providing longer usage times and reducing the need for frequent recharging. Enhanced Performance: Users can expect improved performance with extended battery life, allowing for uninterrupted use of apps, games, and other phone functions throughout the day.

Improved Charging Efficiency: The battery charges quickly and holds the charge well, providing a more efficient power management solution compared to worn-out original batteries. Cons: Installation Complexity: Despite the inclusion of a professional repair tool kit, some users might still find the installation process challenging, particularly if they are not accustomed to DIY phone repairs. Potential for Damage: Improper installation could potentially damage the phone’s internal components. It’s important to follow the instructions carefully or seek professional help if unsure. Warranty Concerns: Replacing the battery yourself may void any remaining warranty on the phone. It’s advisable to check the warranty status and consider the implications before proceeding with a DIY replacement. Initial Calibration: New batteries sometimes require a calibration period, which means the phone may need a few charging cycles to accurately display battery life and performance. Long-Term Reliability: While the initial performance is promising, the long-term reliability of third-party batteries can sometimes be less predictable compared to OEM (original equipment manufacturer) batteries. Heat Management: Upgrading to a higher-capacity battery may result in increased heat generation, especially during intensive tasks or charging. It’s crucial to monitor the phone’s temperature to prevent overheating. Overall, the JUBOTY 3800mAh Battery for iPhone 12/12 Pro offers an excellent solution for extending the battery life and performance of your device. However, careful consideration should be given to the installation process and potential impacts on warranty and long-term reliability.

I purchased this battery for my iPhone 12 Pro, hoping for an upgrade in performance, but it turned out to be a huge disappointment and a potential safety risk. The battery gets very hot during normal use and charging, even when the phone is idle. It also loses charge extremely fast — I tested it with the phone completely powered off, and it still lost over 90% of its charge within just 6 hours. That’s completely unacceptable. Despite following all installation instructions carefully, the battery is clearly defective or unsafe. I’ve removed it from the phone because I don’t feel safe using it. I cannot recommend this product to anyone. Stay away from this battery – it’s not worth the risk to your device or your safety.

Instructions and tools for the replacement are great. Took AGES to get the screen off with the suction cup but got there eventually. Be really careful removing the screen at the top (by the camera lenses) as I cracked mine and this basically ended up costing more to fix than the battery. 😢 Battery works fine and is an big improvement on my 80% battery previously.

Embarking on the DIY journey of battery replacement can be intimidating, but the JUBOTY 3800mAh Battery for iPhone 12 provides a generous boost of confidence. With a promise of 35% more power than the original standard battery, one can't help but be tempted by the prospect of longer phone usage and fewer tethering sessions to the nearest power outlet. This upgrade certainly appeals to those looking to invigorate their iPhone 12's stamina without frequent pit stops for charging. The kit comes with the necessary tools and instructions to facilitate the process, although the tools are admittedly not of the highest calibre. They get the job done, which is ultimately what matters, though a small investment in higher-quality equipment could have sweetened the deal. Upon successful installation, which I recommend pairing with a detailed iFixit guide for additional clarity and tips, the battery's performance was noticeably superior. My iPhone 12 was rejuvenated, holding a charge for an impressively extended duration compared to the original battery. It's worth noting the importance of conditioning the new battery with a full charge cycle to ensure optimal longevity. Be prepared for iOS to throw a temporary fuss, signalling its discontent with the non-Apple battery replacement, but rest assured, this warning is fleeting and will vanish after some use. For those who are not deterred by a short-lived error message and are willing to take on the mantle of battery replacement, the JUBOTY 3800mAh Battery emerges as a cost-effective solution that punches above its weight, providing a noticeable upgrade to your iPhone experience.
