Introduction
Apple has always played a key role in shaping charging standards for consumer electronics. From its early proprietary 2.4A fast-charge technology to its eventual adoption of USB Power Delivery (PD), Apple’s decisions often influence the entire industry. With the release of the iPhone 17 series, Apple has taken another bold step by introducing the AVS (Adjustable Voltage Supply) protocol under USB PD 3.2.
This shift doesn’t just improve how fast your iPhone charges—it changes the way chargers, cables, and accessories are designed. In fact, AVS could become the blueprint for the next decade of charging solutions.
What Is AVS Charging Protocol?
AVS (Adjustable Voltage Supply) is a newly standardized charging method created by the USB Implementers Forum (USB-IF), the global body responsible for USB standards.
Originally, USB PD 3.1 EPR (Extended Power Range) was designed for laptops and high-power devices up to 240W. AVS inherits this flexibility but scales it down for the Standard Power Range (SPR)—devices like smartphones, tablets, and accessories requiring up to 100W.
For a deeper understanding of how AVS integrates with other consumer products, see our page on wall charger manufacturer.
Key features of AVS include:
– Dynamic Voltage Control: Instead of rigid fixed voltage steps, AVS allows continuous adjustment to deliver exactly what the device needs.
– Optimized for Efficiency: Voltage is finely tuned to reduce conversion losses, meaning less wasted energy and less heat.
– Part of USB PD 3.2: Unlike proprietary solutions, AVS is part of an international standard, promoting universal compatibility across devices.
In short, AVS is not just an “incremental update.” It’s a more intelligent and adaptive way to charge devices, focusing on precision and long-term battery health.
Why Apple Chose AVS Over PPS
Until now, most Android manufacturers used PPS (Programmable Power Supply) under USB PD 3.0. PPS allowed variable voltages in 20mV increments, but Apple found it limited in practice.
Reasons Apple prefers AVS over PPS:
1. Voltage Accuracy – While PPS theoretically adjusts in small steps, real-world inefficiencies reduce effectiveness. AVS delivers more precise regulation.
2. Higher Real Power Output – PPS locks maximum power to simultaneous current and voltage conditions, which often lowers actual output. AVS decouples them, enabling the iPhone 17 to achieve real-world 40W sustained and up to 60W bursts.
3. Thermal Management – By shifting more power conversion to the charger side instead of inside the phone, AVS keeps the iPhone cooler during charging.
4. Future Flexibility – AVS integrates smoothly with USB PD’s evolving ecosystem, making it easier to adapt for future iPhones, iPads, and MacBooks.
Key Advantages of AVS for iPhone 17 Users
1. Faster & Cooler Charging – The iPhone 17 can charge to 50% in ~20 minutes, outperforming previous models. Reduced heat allows sustained high-power charging.
2. Better Battery Longevity – AVS lowers charging stress, keeping batteries healthier for longer.
3. Seamless Compatibility – Being part of USB PD 3.2, AVS is not locked to Apple chargers only. Third-party chargers can also support it via firmware updates.
4. Higher Energy Efficiency – Less heat, safer charging, and improved power delivery, especially useful during gaming while charging.
Real-World Charging Performance of iPhone 17
Apple claims:
– iPhone 17: 50% charge in ~20 minutes
– iPhone 17 Air: 50% charge in ~30 minutes
– Peak Power: Negotiation up to 60W, sustained around 35–40W
Independent testers confirm that iPhones charge cooler (2–3°C lower) and more consistently under AVS compared to PD.

Comparison With Apple’s Earlier Charging Protocols
| Protocol | Year Introduced | Applied Models | Max Power | Key Features |
|---|---|---|---|---|
| Apple 2.4A Fast Charge | 2014 | iPhone 6 – 7 | 12W | Proprietary, USB-A to Lightning |
| USB PD (PD 3.0) | 2017 | iPhone 8 – 14 | ~29W (peak ~19W sustained) | PPS support, limited in real results |
| AVS (PD 3.2) | 2024 | iPhone 17 onward | 40W sustained, 60W bursts | Dynamic voltage, cooler charging, longer battery life |
What This Means for B2B Buyers
For distributors, wholesalers, and brand owners, AVS is both a challenge and an opportunity.
Challenges:
– Older PD-only chargers may not unlock full iPhone 17 speeds.
Opportunities:
– Offering AVS-ready chargers differentiates your catalog.
– OEM/ODM services allow private label brands to launch quickly.
– Our services include logo printing, custom packaging, design support, 3-year warranty, and after-sales service.
Conclusion
The iPhone 17 AVS charging protocol is more than a higher wattage upgrade—it’s a smarter, safer, and more efficient way of charging. For consumers, it means faster charging, less heat, and longer-lasting batteries. For businesses, it signals a shift toward adaptive charging standards.
As a factory specializing in AVS-ready chargers, we support partners worldwide with low MOQ, customization, and certified quality. The future of charging is AVS—and it’s already here.
