Key performances
These key points are derived from the lab measurements during testing and do not figure into the overall score. The lab measurements, however, are used for the overall score.
94th
7th
Pros
- Great autonomy, especially in video streaming and calling
- Accurate battery gauge; 100% displayed on screen during charging measured 97.7% of real charged capacity
- Very high adapter efficiency, with low residual power drain from the power grid
Cons
- Weak autonomy in outdoor while browsing social apps
- Limited autonomy regained from 5-minute charging boost
- Relatively high discharging currents during gaming and idling with screen off
The Xiaomi Redmi Note 13 battery had an overall average performance, but this version showed a much stronger performance in autonomy and efficiency than its 5G counterpart, the Redmi Note 13 5G.
Under moderate usage, the Xiaomi Redmi Note 13 lasted more than 56 hours, compared with the 50 1/2 hours of the 5G version. The device showed great autonomy in most outdoor use cases, except when browsing social apps. In most of the calibrated use cases, the Redmi Note 13’s autonomy was around average, while the autonomy of video streaming and calling was considerably above average.
The Redmi Note 13’s 33W charger, which comes with the device, was able to fully charge the phone in 1 hour and 12 minutes, placing it in the top half of our database. However, the charging boost performance was limited by the charger’s power; a 5-minute charge yielded only 3 hours and 44 minutes of additional autonomy.
The Xiaomi Redmi Note 13 showed a slightly below-average performance in efficiency tests. The reason was linked to the relatively poor full-charge efficiency at 75.7%. However, the adapter of the Xiaomi Redmi Note 13 was relatively great, with an adapter efficiency at 92% and below-average residual power drain, whether the device was still connected or not. The discharging currents of Xiaomi Redmi Note 13 were around average, except for streaming videos, which was much lower. But discharging currents of gaming and idling were relatively higher than average.
Compared to other devices in the Essential segment (<$199), the Xiaomi Redmi Note 13 ranked in the top half, thanks to its strong autonomy results.

Autonomy
Xiaomi Redmi Note 13
195
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
Xiaomi Redmi Note 13
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
Xiaomi Redmi Note 13
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

218
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
Xiaomi Redmi Note 13
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

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.
