Google Pixel Fold akkumulátor teszt

The Battery Life Score is made up of three performance subscores: Home/Office, On the Go, and Calibrated Use Cases. Each subscore includes the results of a full range of tests to measure range in all kinds of real-life scenarios.

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

The use of the smartphone on the go puts a strain on autonomy due to additional “hidden” needs, such as the continuous signaling associated with the selection of the cellular network. SBMARK Battery experts take the phone outdoors and perform a series of well-defined activities following the same three-hour travel itinerary (walking, taking the bus, the subway…) for each device

Ehhez a tesztsorozathoz az okostelefon visszatér a Faraday-ketrecbe és a miénkbe a robotok ismételten hajtanak végre egy adott használati esethez kapcsolódó műveleteket (például játék, videó streamelés stb.). 80%-os töltöttségtől kezdve minden eszközt tesztelnek, amíg legalább 5%-os akkumulátort nem használnak fel.

Charging is a full part of the overall battery experience. In some situations where range is at its lowest, knowing how fast you can charge becomes a concern. The SBMARK Battery Recharge Score is made up of two subscores, (1) Full Charge and (2) Quick Boost.

The full charge tests evaluate the reliability of the battery charge indicator; measure how much time and how much energy it takes for the battery to charge from zero to 80% capacity, from 80 to 100% as shown by the user interface, and until fully charged.

With the phone at different charge levels (20%, 40%, 60%, 80%), the quick boost tests measure how much charge the battery receives after being plugged in for 5 minutes. The graph here compares the average range gain with a 5-minute quick charge.

The SBMARK Energy Efficiency Score is composed of two sub-scores, Charge Rate and Discharge Rate, both of which combine data obtained during a typical robot-based usage scenario, calibrated testing and charge rating, taking into consideration battery capacity of the device. SBMARK calculates the product’s annual energy consumption, shown in the graph below, which is representative of overall efficiency during a charge and when in use.

The secondary charge score is a combination of four factors: the overall efficiency of a full charge, related to the amount of energy required to fill the battery compared to the energy the battery can supply; the efficiency of the travel adapter when it comes to transferring power from an outlet to your phone; the remaining consumption when the phone is fully charged and still connected to the charger; and the residual consumption of the charger itself, when the smartphone is disconnected from it. The graph below shows the overall efficiency of a full charge in %.

The sub-discharge score evaluates how quickly a battery discharges during a test, which is independent of battery capacity. It is the ratio of the capacity of a battery divided by its autonomy. A small capacity battery may have the same run time as a large capacity battery, indicating that the device is well optimized, with a low discharge rate.
