Restore the flagship performance of your Honor 300 Pro or 300 Ultra with this HB516586EIW 5300mAh replacement battery. Officially unveiled in December 2024, the Honor 300 series has quickly established itself as a powerhouse in the mid-to-high-end smartphone market, combining cutting-edge processing power with exceptional battery endurance. The 300 Pro and 300 Ultra share the same advanced battery architecture — a 5300mAh high-density cell that represented a significant leap in energy density over previous generations. According to official metrics, the original battery enables over 20 hours of continuous video playback, approximately 15 hours of web browsing, or 8-9 hours of intensive gaming on a single charge. During the GSMArena battery endurance test, the Honor 300 Pro achieved an overall rating of 126 hours, placing it among the top performers in its segment. This Li-ion Polymer cell is engineered to restore that industry-leading battery life, keeping your device running through the longest days without compromise.
100W Wired + 80W Wireless Fast Charging Ecosystem: The HB516586EIW battery is designed to work flawlessly with the device’s comprehensive charging system, one of the fastest available on any smartphone today. For wired charging, it fully supports 100W SUPERVOOC fast charging — according to charging specialist testing conducted by ChargerLAB, when using the official 100W charger, the battery can reach 50% capacity in just 15 minutes, 80% in 28 minutes, and achieve a full charge in approximately 55 minutes. This translates to roughly 2,650mAh of power replenished in just a quarter of an hour — enough to get through the remainder of a full day. For wireless charging enthusiasts, the battery supports 80W wireless fast charging, one of the highest wireless charging speeds available on any Android flagship. Additionally, the battery enables 5W reverse wireless charging, allowing you to top up your earbuds, smartwatch, or other Qi-compatible accessories directly from your phone — a lifesaver when traveling or away from power outlets for extended periods. The charging system also supports 100W PPS (Programmable Power Supply) protocol, which means the battery is compatible with a wide range of third-party USB-C chargers that support PPS, not just the official charger. ChargerLAB’s testing revealed that the AOHi 100W charger achieves 94.2W output on this device, very close to the original’s 95W peak, demonstrating the battery’s excellent protocol compatibility.
Advanced Battery Technology & Long-term Reliability: This battery utilizes third-generation high-density negative electrode material technology, which significantly enhances energy density and low-temperature performance compared to conventional Li-ion cells. Independent industry testing indicates that devices equipped with this technology maintain over 85% of their original capacity even after 800 complete charge cycles under normal usage conditions, providing reliable long-term performance. The high-density cell design achieves a remarkable energy density of approximately 780Wh/L, packing the 5300mAh capacity into an ultra-slim profile that maintains the phone’s premium thickness of just 8.2-8.3mm. Built with Grade A cells and multi-layer safety protection against overcharge, over-discharge, short circuits, and temperature extremes, this battery is certified for safety with CE, RoHS, and UN38.3 standards, ensuring secure daily operation even under demanding conditions.
Compatibility & Installation Guidance: Fits both Honor 300 Pro (model AMP-AN00) and Honor 300 Ultra (model AMP-AN10) — these two models use the identical HB516586EIW battery. Both devices feature the Snapdragon 8 Gen 3 chipset, a 6.78-inch 120Hz AMOLED display with peak brightness reaching 4000 nits, 50MP triple camera systems, and IP65 dust and water resistance certification. Please confirm your battery model before ordering — HB516586EIW is printed on your original battery. If your 300 Pro or 300 Ultra exhibits any of the following symptoms — rapid battery drain, failure to hold a charge, unexpected shutdowns when battery level still shows 15-30%, or visible swelling of the back cover — this replacement battery is the correct solution. Professional installation is strongly recommended as both devices feature a sealed glass back design with strong waterproof adhesives used to maintain the IP65 rating. Removing the back cover without proper heating tools and experience risks cracking the glass or damaging the display. Third-party repair shops typically charge $20-40 for labor on flagship devices, while Honor official service centers offer battery replacement at a fixed price of ¥229 (approx. $31.50) plus a ¥30 labor fee (approx. $4), for a total of approximately $35.50 during their regular service pricing.
Optimized Battery Care for Extended Service Life: To maximize the lifespan of your new 5300mAh Li-ion Polymer battery, we recommend following these best practices based on lithium battery chemistry principles. Avoid full 0% discharges whenever possible — lithium batteries experience the least electrochemical stress when kept between 20% and 80% state of charge. For daily use, partial charges are actually preferable to full cycles; topping up from 30% to 80% multiple times is less taxing than one full 0-100% cycle. The battery prefers a partial rather than a full discharge, and frequent full discharges should be avoided when possible. Do not expose the device to high temperatures — leaving a phone in a hot car during summer or in direct sunlight for extended periods can accelerate capacity degradation by up to 300% compared to storage at room temperature. New batteries typically require 3-5 full charge-discharge cycles to reach optimal performance calibration and capacity reporting accuracy. For best results and fastest charging speeds, use the original 100W charger and cable that came with your device, or any third-party charger that supports 100W PPS. Honor recommends using original accessories to ensure the fastest charging speeds and safest operation. If you notice swelling, overheating during normal use, a sudden drop in runtime (e.g., going from 6 hours to 2 hours of screen time), or the device shutting down unpredictably, stop using the battery immediately and consult a professional technician. When storing the device for extended periods (over 30 days), maintain approximately 40-60% charge in a cool, dry environment between 15°C and 25°C. Storing at full charge or empty charge accelerates degradation significantly. Proper care can substantially extend the usable life of your replacement battery well beyond the standard 90-day warranty period, potentially reaching 2-3 years of satisfactory performance.
