Inside the CNET Lab Phone Charging Speed Test
CNET Lab put 33 phones from Apple, Samsung, Google, Motorola and several China-designed brands through a rigorous phone charging speed test. Each device was drained to 10% or less, then plugged into a charger that matched or exceeded its rated maximum. After 30 minutes of wired charging, testers recorded how much battery percentage each phone gained. The process was repeated on wireless pads using Qi, Qi2 or Qi2.2 chargers, again matching the phone’s supported peak speed. Results from wired and wireless tests were averaged into a single fast charging comparison score for every device. This approach highlights real-world performance instead of marketing numbers, factoring in differences like battery capacity, split-battery designs and newer silicon-carbon cells. The outcome: a clear ranking of the fastest charging phones and a realistic picture of how quickly you can actually get usable power back into your device.
Two Standout Winners: Overall Fastest and Wired Speed Champion
Among all 33 phones, two models set the current charging standard in their categories. The iPhone 17 Pro emerged as the fastest charging phone overall when wired and wireless results were combined. Its advantage is not just peak wattage; a relatively modest 4,252mAh battery means less capacity to refill, so it tops up more quickly despite facing rivals with larger 5,000mAh-class packs. On the wired side alone, Samsung’s Galaxy S26 Ultra led the pack thanks to a new 60-watt charging ceiling, pushing it ahead in pure cable-based speed. Together, these results show that headline wattage is only part of the story. Battery size, chemistry and software efficiency all play crucial roles, and a well-optimized system can outperform competitors that simply advertise bigger charging numbers on the box.
Why Chinese Brands Push Faster Charging Than Apple, Google and Samsung
When you look beyond mainstream brands, many Chinese phones offer dramatically higher charging figures, often 100 watts or more. Devices like the OnePlus 15 can accept up to 100W wired and 50W wireless in their scaled-back versions, with even higher limits on some regional models. Combined with large batteries and features like split cells and silicon-carbon technology, this allows them to jump from 0 to 50% in minutes and reach full capacity in under an hour. By contrast, Apple’s iPhone 17 Pro caps wired charging at 40W and MagSafe wireless at 25W, while Samsung, Google and Motorola still trail those ultra-fast figures. Part of the gap comes from different market expectations and corporate priorities: established brands prioritize long-term battery health, ecosystem stability and universal charger compatibility, whereas aggressive fast-charging designs lean heavily on proprietary standards and specialized accessories.
Do Higher Wattages and New Battery Tech Really Help Users?
Fast charging comparison charts often focus on wattage, but CNET’s tests show user experience is more nuanced. A phone with a slightly slower charger but smaller battery, like the iPhone 17 Pro, can still feel quicker to refuel than a rival with a huge battery and extreme wattage. Silicon-carbon batteries and split-pack designs clearly speed up top-offs, yet they are still limited to a subset of phones and often tied to proprietary chargers. For many people, the difference between a strong 40–60W system and a 100W-plus one only matters if they frequently arrive at 10% battery and need a rapid boost. If your daily routine includes regular overnight charging and moderate daytime top-ups, ultra-fast figures are less critical than overall battery life, software efficiency and reliable, safe performance over years of use.
