23rd
8th
Pros
- Decent autonomy when gaming
- Very good charging time at 57 minutes to a full charge
- Good autonomy recovered after a 5-minute charging boost, with a gain of 6 hours and 29 minutes on average
- Low battery consumption during idle phase, with only 1% drop per night on average
- Great charge efficiency
Cons
- High discharge currents when calling and using the camera on the go
The Xiaomi Redmi Note 12 Pro 5G’s global score was among the best of our database. It had a very similar performance to its predecessor the Xiaomi Redmi Note 11 Pro 5G, showing a slight improvement in the charging experience but a little decline in autonomy when testing individual use cases and on the go.
The Xiaomi Redmi Note 12 Pro 5G’s charge lasted a good 2.5 days when the device was used moderately, with only 1% drop per night on average. When testing individual use cases, the autonomy was slightly above average with good performances when gaming but a poor experience when calling. The autonomy on the go was a bit balanced with decent results when using social apps, but low when using the camera or calling.
The 67W charger filled up the battery in only 57 minutes, faster than the average of our database. The device also recovered a very good 6 hours and 29 minutes of autonomy after a quick 5-minute charge.
Charge efficiency was very good thanks to the adapter’s excellent efficiency and a very low residual power drain whether the fully charged device was plugged in or not. For a large 5000 mAh battery, the device’s discharge currents were average in almost all use cases, except when using the camera or calling, where consumption was high. But discharge currents during idle phases were really good, meaning that the device is quite well but not perfectly optimized.
When compared with other devices from the Advanced price range ($200 – $399), the Xiaomi Redmi Note 12 Pro 5G ranked in the upper part of our database thanks to an excellent charging experience and a decent efficiency. However its autonomy score was slightly below average for this segment.

Autonomy

Autonomy score is composed of three performance sub-scores: Home / Office, On the go, and 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.

Home/Office

221
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.
On the go

195
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 outdoors and perform a precisely defined set of activities while following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device
Calibrated

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.
Charging

Charging is fully part of the overall battery experience. In some situations where autonomy is at a minimum, knowing how fast you can charge becomes a concern. The DXOMARK Battery charging score is composed of two sub-scores, (1) Full charge and (2) Quick boost.
Full charge

224
Full charge tests assess the reliability of the battery power gauge; measure how long and how much power the battery takes to charge from zero to 80% capacity, from 80 to 100% as shown by the UI, and until an actual full charge.

Quick boost

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. The chart here compares the average autonomy gain from a quick 5-minute charge.
Efficiency

154
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, calibrated tests and charging evaluation, taking into consideration the device’s battery capacity. DXOMARK calculate the annual power consumption of the product, shown on below graph, which is representative of the overall efficiency during a charge and when in use.
Charge up
Xiaomi Redmi Note 12 Pro 5G
205
The charge up sub-score is a combination of four factors: the overall efficiency of a full charge, related to how much energy you need to fill up the battery compared to the energy that the battery can provide; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the residual consumption when your phone is fully charged and still plugged into the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The chart here below shows the overall efficiency of a full charge in %.
Discharge

194
The discharge subscore rates the speed of a battery’s discharge during a test, which is independent of the battery’s capacity. It is the ratio of a battery’s capacity divided by its autonomy. A small-capacity battery could have the same autonomy as a large-capacity battery, indicating that the device is well-optimized, with a low discharge rate.
