Introduction
Earlier this year, the budget phone Samsung Galaxy A56 was released, It measures 7.4mm thick, weighs 198g, and comes with a built-in 5000mAh battery. And it featuring 45W fast charging—the same as the high-end S25 Ultra. We found this puzzling and conducted a charging compatibility test, and the results were unexpected. Let’s take a look!
Charging Protocols Supported by the Phone
First, let’s take a look at whether the Samsung Galaxy A56 supports more universal fast-charging protocols such as PD and PPS.
Using Apple’s 140W charger, the ChargerLAB POWER-Z KM003C detected the triggered protocol as PD.
Switching to the MOVESPEED 65W charger, the protocol this time was PPS.
Charging Compatibility Test
Original Chargers
When charging the Galaxy A56 with the Samsung GaN 65W 2C1A charger, the output was 8.47V 3.08A 26.04W.
We tested a range of Samsung’s original chargers with different power ratings, all paired with the original dual USB-C cable. The maximum charging power we measured was around 26W—below the official claim.
Visualized in a bar chart, the Samsung GaN 45W charger achieved the highest power at 26.52W. Overall, the differences between Samsung’s own chargers were minimal, with results falling in the 22–27W range.
Third-party Chargers
After the official chargers, we moved on to third-party options—testing over a hundred models in total.
Starting with the MOVESPEED 200W charger, we got an unexpected result: 9.17V 3.78A 34.43W.
The performance was very stable, mostly triggering the 9V voltage level. A few chargers fell back to 5V, with currents ranging from 1A to 4A. Compatibility was broad, and power delivery remained steady.
In fact, the only two chargers that consistently reached around 34W were the MOVESPEED 65W and 200W, delivering 34.77W and 34.51W respectively. Overall, the Galaxy A56’s charging power clustered around three levels: 14W, 26W, and 34W, with PPS and PD protocols supported.
Power Banks
Finally, we tested power banks. With the CUKTECH NO.15 Ultra, charging power reached 8.84V 2.97A 26.24W.
Summarizing the data in a table, we found the compatibility with power banks was quite similar to that of third-party chargers: typically triggering the 9V voltage level with currents between 1A and 4A.
In graph form, the results again resembled third-party chargers. For instance, the llano 65W 20000mAh power bank delivered about 29W. Its triggered protocols matched those of third-party chargers, supporting PD, PPS, and QC.
Summary of ChargerLAB
Overall, the Samsung Galaxy A56’s charging power is clearly limited by the device itself. With original Samsung chargers, charging power stayed between 22W and 27W. Among third-party chargers, MOVESPEED’s two models managed to reach around 34W, while most others remained steady in the 14W–29W range, typically at the 9V voltage level and 1A–4A current. Power bank performance was very similar, mostly delivering 26W–29W under the same 9V profile, with support for PD, PPS, and QC protocols.
Although the Galaxy A56 is marketed as supporting 45W fast charging, the actual maximum power never reached that level, leaving it behind Samsung’s high-end models. That said, it demonstrated strong cross-device compatibility—whether using original chargers, third-party adapters, or power banks, the phone was able to charge stably, more than sufficient for everyday needs.
The Samsung Galaxy A56 successfully passed the ChargerLAB Compatibility 100 Test. Below is the compatibility 100 test report issued by us.
