It's a fact that almost every manufacturer has its own fast-charging technology. We know Qualcomm Quick Chargebut it is also OnePlus Dash/Warp Charge...or the proprietary systems of Meizu, Samsung, and other companies. Well, Google could end thatand force manufacturers to standardize fast charging on Android phones around USB Power Delivery to ensure interoperability and security.
Google will standardize fast charging
Micro USB standardized cables and charging systems. Basically, it was possible to charge any Android phone with any charger, and in principle, there were no incompatibilities. However, This has changed with USB Type-CNot all chargers are compatible due to the proprietary fast charging technologies they include, and some may even generate security risks if they alter the voltage outside of the defined levels.
Therefore, this poses a problem for many users, who can no longer be sure that all chargers are compatible. But that will change with Android 7.0 NougatBecause Google is going to force the standardization of the USB Type-C connection that Android devices have, according to the Android Compatibility Definition Document.
According to that document, devices with USB Type-C They should avoid proprietary methods that modify the Vbus voltage beyond the predetermined levels. The guide indicates that, if this recommendation is not followed, Problems may arise when combining chargers, different cables or devices: from slower charging to the phone not charging at all, malfunctioning, or overheatedFurthermore, Google makes it clear that this recommendation could become a requirement for manufacturers who want to certify their equipment with the Google ecosystem of apps and services.
Meanwhile, all manufacturers They will have to ensure compatibility with USB Power Delivery (USB-PD)The standard chosen by Google for charging via USB-C allows for dynamic negotiation of voltage and current based on the capabilities of the charger, cable, and phone. This interoperability reduces incompatibilities and improves performance. security, versus proprietary solutions that force out-of-specification voltages.
- What is USB-PD: USB-IF flexible standard that negotiates power profiles, supports multiple voltage levels and, with PPS, granularly regulates current.
- Key benefits: Cross compatibility, finer thermal control, and reduced risk when mixing chargers and cables from different brands.
Could Quick Charge disappear?
This means that technologies such as Quick Charge, or Dash Charge, could be destined to disappear. Or at least, they would have to meet standards that would ultimately make Qualcomm or OnePlus technology offer nothing different from the others. Yes, perhaps some improvement over the others, but all would have to meet mandatory minimums that would make manufacturers lose interest in having proprietary technologies that stand out especially, which in turn would mean having to make significant investments in Investigation and development.
In practice, Google doesn't force you to abandon trademarks, but it does require you to align interoperability with USB-PD. Many "smart" chargers use algorithms to speed up charging by adjusting voltage and amperage, but if this is done outside of USB-C rules, The problems are multiplying When mixing accessories: the phone may charge more slowly, fail to start charging, display errors, or trigger thermal limits. This guideline affects Qualcomm, OnePlus, OPPOHuawei and MotorolaAmong other things, they must guarantee full compatibility with USB-PD and avoid modifying Vbus outside of specification.
How it affects you and good charging practices
Standardization aims to any USB-C charger and ensure that any certified cable works flawlessly, prioritizing safety and user experience. While this standard is being rolled out across the entire ecosystem, it's advisable to follow these guidelines:
- Prefers USB-PD: Use certified chargers and cables; avoid mixing proprietary systems if you don't know their actual compatibility with USB-C.
- Watch the temperature: If the phone gets hot, the internal management system will reduce power to protect the battery; charge it in a cool environment with the screen off.
- Minimize risks: If you encounter problems, try another USB-PD cable/charger; if the problem persists, the phone may be limiting charging for safety reasons.
- Take care of the battery: alternate fast charging with slower loads (for example, a lower-power PD charger, the computer's USB port, or Qi wireless charging, which is usually slower).
- System functions: activates the optimized load when available; it reduces stress on long stretches and helps with battery longevity.
This would allow us to re-establish a standard where any charger, with any cable, can charge our Android phone or tablet. Something we had before, lost, and are destined to regain. Google's direction with USB-PD points to a more integrated ecosystem. simple, secure and interoperablewhere speed coexists with battery protection and universal compatibility.
