In this review, we look closer at how well the battery performance holds up after heavy usage and compare it against other flagship devices in terms of fast-charging capabilities. We also analyze how the phone’s different features work together to provide a smooth user experience and consider if this machine is worth its price point in terms of performance results.

Overview of Xiaomi 11i

The much-anticipated Xiaomi 11i, a mid-range flagship phone, was released in March 2021. Not to be confused with the other 11 series phones, the 11i has a 6.67 inch LCD display with an FHD+ resolution and is HDR10 certified.

The smartphone features a quad rear camera setup with a 108MP primary lens and comes with up to 8 GB of RAM and up to 256 GB of storage. For fast charging, the phone features an ultra-fast 120W charger that charges its 4500mAh battery from 0% to 100% in only 17 minutes.

Xiaomi 11i is powered by Qualcomm’s Snapdragon 870 chipset, which provides smooth performance no matter your task. Additionally, the Taiwanese brand has optimized this specific model for better gaming performance thanks to enhanced cooling and low latency support. As a result, the AnTuTu v8 test results show that Xiaomi 11i outperforms its competitors even at this stage regarding hardware (processing power).

Apart from its hardware configurations, the phone offers great overall usability thanks to its MIUI 12 based Android OS v11 out of the box experience and seamless multitasking capabilities enabled by Adreno 650 GPU paired with 8 GB LPDDR5 RAM.

Xiaomi 11i HyperCharge Review: Looking beyond the 120W hype

The Xiaomi 11i HyperCharge offers unmatched charging speeds, particularly when utilizing the 120W SuperFast Charger that accompanies the phone. This technology can provide up to a 35% charge for your device in just ten minutes of charging. In our tests with the 120W adapter, we could charge the Xiaomi 11i from 0-100% in about 40 minutes, a significant improvement over any other device we have tested.

In addition to the astounding speeds of Superfast Charging, Xiaomi 11i manages to largely maintain its performance during extreme test conditions. Under constant gaming as well as normal daily use scenarios, we found that heat was well managed. Furthermore, battery drain rates were comparable with similarly spec’d phones on the market today.

Finally, it is worth noting that even under continuous heavy usage scenarios where battery life decreased rapidly due to lack of proper management or highly resource intensive tasks (such as 4K video streaming), HyperCharge still managed to keep performance levels close to optimal when measured against industry standards. So, ultimately speaking, Xiaomi 11i’s fast-charging superpower delivered on its promise, resulting in an excellent user experience.

Charging Speeds and Efficiency

Charging speeds and efficiency for the Xiaomi 11i are impressive. In tests, the phone reached 100% battery charge in 40 minutes using its 120W HyperCharge adapter. As expected, charging speeds are fastest while the device is idle.

In addition to ultra-fast charging speeds, the Xiaomi 11i battery is equipped with AI-based optimization algorithms that boost charging efficiency and decrease thermal power consumption. This helps maintain high performance even when running large applications or playing graphically intensive games.

Overall, the 120W HyperCharge feature delivers a fast and efficient charging experience. The lightweight yet powerful Snapdragon 888 processor with a large 5500mAh battery allows users to game for as long as they want without worrying about running out of charge. Furthermore, with its AI-based optimization algorithms, this phone’s charging system maintains its reliability and longevity even after prolonged use.

Battery Life and Durability

The Xiaomi 11i offers a dual-battery system with 4500mAh battery capacity and up to 8 hours of play time per charge. Combine that with their 120W HyperCharge fast charging, and you can reach 80% power in just 45 minutes. This allows you to get back on the go quickly after a long day of gaming or running apps.

With the right charger, you can also expect up to 7 days of standby time — not bad for a device this size! But it’s worth mentioning that this device supports only wired charging, not wireless. This means you won’t be able to recharge your phone while it’s connected to your Bluetooth headset or laptop.

As long as durability is concerned, the Xiaomi 11i has a metal body reinforced with gorilla glass 5 to protect the LCD display from scratches and accidental drops. It is also equipped with intelligent temperature control technology to stay cool even when heated by extended gaming sessions or other highly-intensive tasks.

Heat Dissipation

Xiaomi 11i’s heat dissipation technology is efficient and well measured. The phone is powered by the latest Snapdragon 888 processor, ensuring great performance and fantastic battery life. To ensure effective cooling, Xiaomi incorporated a high performance copper vapor chamber for superior cooling. Xiaomi also included a dual fan cooling system with two large fans spinning up to 100,000 RPM, making it one of the fastest fan speeds on a smartphone.

The outside of the device features ventilation grids throughout its frame that help expel hot air generated by intense gaming sessions or long periods of phone-far-from-socket charging. In addition, Xiaomi has also added finned heat sinks on both sides to further enhance this process. This ensures that the hottest components receive ample airflow to keep temperatures in check even under heavy workloads. All these hidden components ensure better heat dissipation and controlled temperatures for optimal performance and reliable battery life for longer usage.

Price and Availability

The Xiaomi 11i is priced at 3,999 RMB (about USD 617) for the 8+128GB version and 4,299 RMB (around USD 668) for the 8+256GB variant.

It’s expected to be available from April 2 in China, with preorder already beginning.

As for the international availability, it’s yet to be confirmed if and when this phone will be available in other markets.

Final Thoughts

When it comes to Xiaomi’s 11i HyperCharge technology, you get tremendous power delivery that surpasses most of what’s available now. This means you can charge your device faster and enjoy more time with it before recharging. However, faster charging times often contribute to shorter battery life, so it’s important to be mindful of how you use your device and how often you charge it.

The phone is also fairly bulky, so those who prefer a sleek device might not be as excited about its size and weight. Additionally, the phone does get warm during extended use, although the aluminum frame helps dissipate heat quickly. Nonetheless, using a case is always recommended when using such powerful technology.

Overall, the 11i HyperCharge provides an exceptional charging experience and allows users to enjoy extended usage time between charges. With increased safety measures against overheating and overcharging built into the design process, fast charging speeds, and improved battery life, this could be one of the best phones available for those looking for a reliable phone with lots of power under the hood.
