The Find X9 model with the largest battery is the Oppo Find X9 Pro. It features a battery capacity of over 7,410mAh, a significant increase from the previous Find X8 Pro's 5,910mAh battery. This represents nearly a 25% boost in battery capacity while maintaining the same slim thickness of 8.25mm, a notable engineering achievement given that larger batteries traditionally lead to bulkier devices. This battery upgrade is designed to provide much longer endurance, which is particularly valuable for users who engage in heavy smartphone activities such as gaming, streaming, social media, photography, and productivity throughout the day.
In comparison, the standard Oppo Find X9 model comes with a battery that exceeds 6,630mAh, also representing a significant increase of more than 1,000mAh over its predecessor, the Find X8, which had a 5,630mAh battery. Despite this boost in battery capacity, the Find X9 maintains a slim profile with a thickness of just 7.99 to 7.9mm, continuing Oppo's trend of delivering powerful batteries without compromising on device slimness or style.
The advancements in battery capacity for both Find X9 models likely stem from improvements in battery chemistry, internal battery stacking designs, and better cooling systems, allowing Oppo to pack more battery life into a slim and safe-to-use form factor. This kind of innovation responds to common user concerns about battery anxiety, ensuring that the device can last a full day or more under typical or even heavy use situations without requiring a power bank.
Regarding charging, the Oppo Find X9 Pro supports 80W wired fast charging and 50W wireless charging, making it one of the leaders in fast charging technology. This complements its large battery, allowing users to recharge quickly even after heavy usage.
The Find X9 series also boasts other top-tier features such as MediaTek's Dimensity 9500 chipset, advanced AMOLED displays with 1.5K resolution and 120Hz refresh rates, and sophisticated camera arrays featuring multiple 50MP sensors including Sony and Samsung lenses. The Pro model, in particular, includes a 200MP periscope lens and additional specialized sensors, underscoring its position as Oppo's premium flagship.
In summary, the Oppo Find X9 Pro holds the title for the Find X9 model with the largest battery, offering a groundbreaking 7,410mAh capacity packed into an ultra-slim frame, delivering enhanced endurance and user convenience along with fast charging and flagship performance capabilities. The standard Find X9 also offers a substantial battery upgrade over its predecessor, making the entire series stand out in terms of battery life advancements for 2025 flagship smartphones.
