Restore the full power and extended endurance of your Infinix Note 30 5G with this premium BL-49TX 5000mAh replacement battery. The Infinix Note 30 5G, launched in June 2023, features a 6.78-inch FHD+ 120Hz display, MediaTek Dimensity 6080 5G processor, and one of the most advanced charging systems in its class — supporting 45W All-Round FastCharge with Bypass Charging technology. This Li-ion Polymer battery is engineered to meet or exceed the original specifications, providing reliable, long-lasting power for your daily activities.
Designed for the 45W Fast Charging System with Bypass Technology: The Infinix Note 30 5G features a 45W All-Round FastCharge system that can charge the 5000mAh (typ) battery to 75% in just 30 minutes[reference:6]. More importantly, the phone is equipped with Bypass Charging mode, a feature typically found on gaming phones. When enabled at approximately 30% battery, the charging current bypasses the battery and goes directly to the motherboard, reducing temperature increase by up to 7°C during simultaneous charging and gaming[reference:7]. This significantly extends overall battery lifespan by minimizing heat stress — heat is the single biggest enemy of Li-ion batteries. Our BL-49TX replacement battery is fully compatible with both standard 45W charging and the Bypass Charging mode, ensuring you can continue to enjoy the phone’s full set of intelligent charging features after replacement.
Built for 1000 Charge Cycles — 25% Longer Than Industry Standard: One of the standout features of the original Infinix Note 30 5G’s battery system is its durability — the battery is rated for up to 1000 charge cycles, which is 25% higher than the traditional industry standard[reference:8]. This means under normal use, your battery should maintain good performance for over two years before noticeable degradation. Our BL-49TX replacement battery is built with Grade A cells and high-density Li-ion Polymer technology to match this extended cycle life. Whether you’re streaming video, browsing social media, or playing graphics-intensive games, you can expect consistent, reliable power delivery for the long haul.
Reverse Charging Capability — Turn Your Phone Into a Power Bank: The Infinix Note 30 5G supports wired reverse charging, allowing you to share power with other devices such as earbuds, smartwatches, or even a friend’s phone in an emergency[reference:9]. Our BL-49TX replacement battery retains this full functionality, meaning your newly restored phone can still serve as an emergency power source for your other gadgets. This is particularly useful for travelers or anyone who carries multiple portable devices.
User-Guided Installation Tips for Infinix Note 30 5G: Installing a new battery in the Infinix Note 30 5G requires more care than older phones with removable backs, but it is a manageable DIY task for those with basic repair experience. Key steps to remember: 1) Use a heat gun or hair dryer on low setting (approximately 70°C) to soften the adhesive holding the back cover — do not overheat or concentrate heat in one area for too long. 2) Use a plastic pry tool, never metal, to avoid scratching internal components or puncturing the old battery. 3) After removing the old battery, clean any residual adhesive from the phone frame before installing the new battery. 4) Test the new battery by connecting it and powering on the phone before applying new adhesive and sealing the back cover. 5) Use the included replacement adhesive strips to reseal the phone — a proper seal is important for maintaining the device’s IP53 dust and splash resistance rating. If you are not confident performing the replacement yourself, most phone repair shops charge $20-35 USD for labor, and we recommend professional installation for users without prior repair experience.
Quality Certifications and Compatibility Assurance: Each BL-49TX battery is brand new, factory-tested, and built with multi-layer safety protection against overcharge, over-discharge, short circuits, and overheating. Certified with CE, RoHS, and UN38.3 safety standards, our battery is safe for international shipping and daily use. It is 100% compatible with Infinix Note 30 5G (X6711), as well as Infinix Note 30 (X6833, X6716) and Infinix Note 30i models that use the same BL-49TX battery part number. If you are unsure whether your device uses the BL-49TX battery, please check the label on your original battery before ordering.
Battery Care Tips for Longest Lifespan: To maximize the life of your new BL-49TX battery, we recommend the following best practices based on official Infinix maintenance guides: Avoid letting the battery drop below 20% on a regular basis — deep discharges accelerate wear. For daily use, try to keep the charge level between 20% and 80% for optimal longevity. When storing the phone for extended periods (weeks or months), keep the battery at approximately 50% charge and store it in a cool, dry place. Always use a certified 45W charger and original USB cable to ensure proper voltage regulation. Enable the phone’s built-in power-saving features when you need to extend battery life. If you plan to game while charging, turn on Bypass Charging mode in the phone’s settings to preserve battery health and reduce heat[reference:10]. If you notice any swelling, overheating, or physical damage to the battery, discontinue use immediately and recycle the battery at a certified e-waste facility — do not dispose of lithium batteries in regular household trash.
