If you've ever wondered why some chargers charge your Nothing Phone faster than others, the answer lies in the loading protocols. USB PD (Power Delivery) and PPS (Programmable Power Supply) are two key technologies in fast charging, but they often cause confusion.
In this article (based on the Excellent explanation by RohitPakalapati), we explain what they are, how they work and why choosing the right charger can make all the difference in the speed and loading safety of your device.
What is USB PD?
USB Power Delivery (PD) It is a fast charging standard that allows devices and chargers communicate to select the optimal power level.
In the past, traditional USB charging only offered 5V, This was sufficient for older devices, but insufficient for modern smartphones with high-capacity batteries. USB PD, This limitation was overcome by introducing higher voltage levels, such as 5V, 9V, 15V and 20V.

This means your Nothing Phone and the charger negotiate a suitable voltage level for maximize loading speed without compromising safety. For example, if your device supports fast charging of 18W, The charger can be adjusted to 9V to optimize the process.
However, USB PD has a limitationIt only works with fixed voltage levels. This may not be the most efficient way to supply power in all situations.
What is PPS and why is it an improvement on USB PD?
PPS (Programmable Power Supply) It is an advanced feature within the standard. USB PD 3.0. Unlike conventional USB PD, which works with predefined voltages, PPS allows for dynamic adjustments in small increments in real time.
Imagine a smart faucet:
- If you need to fill a glass, it provides a steady and moderate flow.
- If you fill a bucket, increases flow to speed up the process.
- When the bucket is almost full, reduces flow to avoid spills.
PPS works similarly, adjusting the voltage throughout the entire charging cycle for minimize energy loss in the form of heat. This translates into a More efficient and safer charging, This is key for the Nothing Phone, which seeks to balance battery performance and durability.
Why is PPS important?
When the load is carried out on a incorrect or too fast voltage, is generated heat, which is detrimental to both loading speed and battery life.
That's why modern devices implement protection mechanisms that slow down the charging process when too much heat is detected.
PPS solves this problem by intelligently adjusting the power.. As a result:
- Heat generation is reduced.
- The loading speed is maintained without risk.
- The long-term health of the battery is improved.
Without PPS, Your Nothing Phone will continue to charge quickly, but not in the most efficient way possible.

Fast charging on the Phone (3a) Series
He Nothing Phone (3a) It is compatible with fast charging via USB PD and PPS. This is one of the reasons why Nothing has opted for an optimized charging ecosystem, offering their own chargers such as the Nothing 45W.
If you use a charger PPS compatible (like Nothing or any other with USB-C PD 3.0 and PPS), you will get:
- Unlimited charging speed.
- Less heat generation.
- Better long-term battery preservation.
If you use a charger without PPS, The phone will continue to charge quickly, but it will not reach its maximum efficiency potential.
Recommended chargers:
Here is a small selection of recommended chargers with 45W PPS technology:
If you want the better charging experience for your Nothing Phone, Ideally, you should choose a charger that supports this technology. This will ensure you get a fast, efficient and safe charging, extending your battery life and ensuring the improved performance for your device.
