The HONOR X9d overcame countless obstacles with a 48-hour durability test at Dinh Mountain.

Mount Dinh, a popular trekking route near Ho Chi Minh City, has long been a favorite among young people due to its diverse terrain, dense old-growth forests, numerous deep streams, and rapidly changing weather at different altitudes.

This diverse natural setting has become the location for Vietnamese Gen Z to undertake a 48-hour challenge with the HONOR X9d – a durable newcomer recently launched on the pedestrian street and quickly becoming the most talked-about phone lately, boasting an 8,300 mAh battery, SGS 5-star durability rating, and IP69K water and dust resistance.

Can an 8,300mAh battery survive a 48-hour test?

The HONOR X9d features a third-generation 8,300 mAh silicon-carbon battery, a class-leading capacity with a lifespan of up to 6 years. During the test at Dinh Mountain, the X9d was subjected to harsh conditions of heat, humidity, continuous uphill climbing, constant light changes, and intensive use to test the battery's performance.

Right from the foot of the mountain, the 48-hour countdown timer was activated, and the HONOR X9d began its journey with 100% battery. Throughout the trekking trip, the device became a "multipurpose assistant" for the whole group: turning the screen brightness to maximum to view the map, recording video , taking photos, and constantly checking the route.

After more than two and a half hours of uphill climbing, the battery level remained at 100%. Approaching the three and a half hour mark and conquering one-third of Mount Dinh, the battery was still at 99%. After more than five hours of trekking to the summit of La Ban, the HONOR X9d still maintained 93% battery. At 4:30 PM, after nearly six and a half hours of continuous travel, the battery remained stable at 92%. Even after watching movies, listening to music, and playing games non-stop in the evening, the battery was still at 64% at 11:26 PM.

On the second day at Suoi Da Nam Ho, when the action cam's battery was down to 28%, the HONOR X9d continued to "carry the team" with its 7.5W reverse charging capability, acting as both a power bank and a smooth shooting and recording device. Even when the battery level dropped to single digits, the ultra-power saving mode was activated, and with only 2%, the device still maintained many tasks as advertised. At the end of the challenge, the HONOR X9d still persevered with 1% battery and did not shut down, completing the full 48-hour endurance test. This proves the HONOR X9d's long-lasting energy with the ability to be used for more than 48 hours.

Endurance test: dropping, bumping, and… chopping watermelon.

Mount Dinh, with its steep, rocky, and slippery surface, presented an extremely challenging test for a smartphone without a screen protector. Even during the initial climb, when a member was running and filming, the HONOR X9d fell heavily onto the road, scratching the screen protector. However, upon removal, the glass underneath remained intact, the touch function was smooth, and the frame showed no signs of deformation. Huy Hoang (from the Vietnamese GenZ group) exclaimed, "The HONOR X9d is truly incredibly durable, deserving of the Swiss SGS 5-star durability certification!"

At dinner, an unexpected incident occurred when boiling hotpot broth spilled directly onto the X9d. Immediately afterward, the team pushed the limits further by using the edge of the phone to cut a watermelon in half. Despite overcoming all the challenges, from drop tests to watermelon slicing, the HONOR X9d only suffered minor scratches to the frame, while the glass, back panel, touchscreen, and all features remained fully functional until the end of the test.

X9d Overcoming countless obstacles: IP69K water and dust resistance rating.

Upon entering the stream area, the HONOR X9d unexpectedly slipped from the hand right at the water's edge and was splashed directly onto its body. Thanks to its wet-finger touch sensor and ability to be used even with gloves on, the HONOR X9d still responded quickly. Members of Gen Z Vietnam praised this as a significant advantage of the IP69K water and dust resistance rating, which is rare in this price range.

At Nam Ho rocky stream, the group further increased the challenge by placing the device directly under the fast-flowing water, allowing the water to pour directly onto the device. The HONOR X9d still kept its screen on and the touchscreen working normally. One member even sat in the stream, soaking in the water while playing PUBG smoothly without any interruptions.

HONOR X9d - A remarkably durable smartphone with practical camera and AI features.

Despite the focus on durability and battery life, the HONOR X9d in the video still demonstrates stable photo and video capabilities in real-world conditions. On the summit of La Ban, where the light constantly changes due to rapidly moving clouds, the 108MP camera still retains detail in the sky, the dark areas on the mountain don't appear "completely black," and the skin tones of the subjects appear natural, as noted by the reviewer regarding HDR and skin tone capabilities.

The X9d's AI features are also fully equipped for quick and efficient content creation, such as removing cropped tree branches at the beginning of shots while naturally recreating the sky behind them. The AI ​​Image Expansion feature is also used to "expand" slightly cramped frames taken hastily during travel. In addition, the X9d boasts other outstanding AI features such as AI translation, Gemini, circle search, etc.

The HONOR X9d comes with configuration options of 8+256GB, 12+256GB, and 12+512GB, priced at VND 9,990,000, VND 10,990,000, and VND 11,990,000 respectively.
