  • Very good autonomy (60 hours of moderate use)
  • Very fast charging (25 minutes to reach 80%)
  • Impressive efficiency, very well-optimized device


  • Low autonomy when calling on the go
  • High residual power drain when device is plugged in

The Realme GT Neo 2 5G is a well-balanced device with good performances in all our Battery protocol test categories.

We compared the Realme GT Neo 2 5G’s performance in several key categories with two other high-end devices, the Xiaomi 11T and the Oppo Reno6 5G; battery capacity, tested charger, display type, and resolution, and processor specifications for all three devices are shown in the table below.

Autonomy (74)

How long a battery charge lasts depends not only on battery capacity but also on other aspects of the phone’s hardware and software. The DXOMARK Battery autonomy score is composed of three performance sub-scores: (1) Stationary, (2) On the go, and (3) Calibrated use cases. Each sub-score comprises the results of a comprehensive range of tests for measuring autonomy in all kinds of real-life scenarios.

All three devices go toe-to-toe in our Autonomy tests, with the Realme GT Neo 2 5G just edging both the Xiaomi and the Oppo for overall results.

Linearity is also a strong point for the Realme GT Neo 2. Its battery gauge has excellent accuracy: when the UI shows 20% remaining charge, the actual remaining charge is 20.4%.

A robot housed in a Faraday cage performs a set of touch-based user actions during what we call our “typical usage scenario” (TUS) — making calls, video streaming, etc. — 4 hours of active use over the course of a 16-hour period, plus 8 hours of “sleep.” The robot repeats this set of actions every day until the device runs out of power. 

The Realme device lasted about 64 hours in our TUS tests, about 3 hours less than both the Xiaomi 11T and the Oppo Reno6 5G. However, the Realme GT Neo 2 5G was particularly stable at night, losing on average only 0.33% of its battery charge, which is the lowest value in all our database.

Using a smartphone on the go takes a toll on autonomy because of extra “hidden” demands, such as the continuous signaling associated with cellphone network selection, for example. DXOMARK Battery experts take the phone outside and perform a precisely defined set of activities while following the same three-hour travel itinerary for each device.

The Realme’s on the go results place it slightly below the Oppo device and just ahead of the Xiaomi. The Realme GT Neo 2 showed a particularly stronger   performance agains the other devices in GPS navigation.

For this series of tests, the smartphone returns to the Faraday cage and our robots repeatedly perform actions linked to one specific use case (such as gaming, video streaming, etc.) at a time. Starting from an 80% charge, all devices are tested until they have expended at least 5% of their battery power.

The Realme GT Neo 2 5G comes in quite a ways ahead of its two rivals in this category, with a great performance for multimedia usages in general, particularly for music and video streaming.

Charging (101)

The DXOMARK Battery charging score is composed of two sub-scores, Full charge and Quick boost. Full charge tests assess the reliability of the battery power gauge; measure how long it takes to charge a battery from zero to 80% capacity and from 80 to 100%; and measure how long and how much power the battery takes to go from an indicated 100% to an actual full charge. With the phone at different charge levels (20%, 40%, 60%, 80%), Quick boost tests measure the amount of charge the battery receives after being plugged in for 5 minutes.

Power consumption and battery level during full charge

It takes 40 minutes 41 seconds for the Realme GT Neo 2 to fully charge its 5000 mAh battery, which is currently the third-best performance in the high-end segment. It is slightly better than Xiaomi 11T (46 minutes 40 seconds) even though they have the same battery capacity and the Xiaomi charger is 67W. With its smaller-capacity battery, it comes as no surprise that the Reno6 5G achieves a full charge faster (34 minutes 53 seconds).

By plugging in the Realme smartphone for 5 minutes with less than 50% of battery level remaining, users will gain more than 8 hours of autonomy. These are better results than the Xiaomi 11T but behind the Oppo Reno6 5G.

Efficiency (99)

The DXOMARK power efficiency score consists of two sub-scores, Charge up and Discharge rate, both of which combine data obtained during robot-based typical usage scenario testing, outdoor mobility testing, charging evaluation, and power measurements, and then take into consideration the device’s battery capacity.
