Fast Charging Compared: Wattage, Standards, and Real Charge Times Across Our 11 Phones
From 20W to 90W, the gap between the fastest and slowest phone we’ve reviewed is 4.5x — and it has nothing to do with battery capacity. Here’s what actually determines how fast your phone charges.
Battery capacity gets most of the attention in phone reviews, but the number that actually shapes daily life is different: how long you're standing next to an outlet waiting for the thing to be usable again. Wired charging power on our 11 reviewed phones spans a genuinely enormous range, from 20W to 90W — a 4.5x difference that has nothing to do with which phone lasts longer on a single charge, which is the question our battery life ranking already answers. This is a different question entirely: when you do need to top up, how long does it actually take, and why does the gap between phones stay this wide four years into the industry's fast-charging arms race?
The Wattage Spread: 20W to 90W Across 11 Phones
Sorted from fastest to slowest peak wired charging speed, the lineup breaks into four rough tiers. At the top, the Xiaomi 14's 90W HyperCharge stands alone — Xiaomi's own testing and third-party lab measurements both put a full 0-to-100% charge at around 35 minutes, faster than most laptops take to update their firmware. Just behind it, the HONOR Magic6 Pro's 80W SuperCharge reaches 80% in about 29 minutes and a full charge in roughly 71 minutes, helped by a silicon-carbon battery cell that HONOR says tolerates the thermal stress of high-wattage charging better than a conventional lithium-ion cell of the same size — a detail we go into further in our full Magic6 Pro verdict. The Nothing Phone (2) sits in a clear middle tier at 45W wired, roughly half Xiaomi's speed but still meaningfully quicker than anything from Apple, Samsung, or Google in this comparison.
The third tier — Pixel 8 Pro and Xperia 1 V, both at 30W wired — represents what used to count as fast charging just a few years ago and now reads as merely adequate next to the leaders. And the bottom tier is the most crowded: Galaxy S24, Galaxy A54, and Galaxy Z Flip5 all cap out at 25W, while the entire Apple lineup in this comparison — iPhone 15, iPhone 14, and iPhone SE — tops out at 20W wired, a number Apple has barely moved in years despite obvious room to go faster.
Why Apple and Samsung Are Charging Slower Than They Could
Neither Apple nor Samsung lacks the engineering to build 80W-class charging — both companies build phones with excellent thermal management and, in Samsung's case, has previously shipped 45W charging on other Galaxy models. The more likely explanation is a deliberate trade-off around long-term battery cell longevity: charging at very high wattage generates more heat and more chemical stress on a lithium-ion cell, and both companies have leaned publicly on multi-year battery health guarantees (Apple targets 80% capacity retention after 1,000 charge cycles) that get harder to hit at higher sustained charging speeds. Xiaomi and HONOR are making the opposite bet — prioritizing charging speed and accepting whatever additional battery wear that entails, wagering that most owners upgrade before degradation becomes the deciding factor. It's the same tension that shows up in age-related battery health, which quietly caps how much any used phone is worth regardless of its original spec sheet.
Wireless Charging Tells a Similar Story, With One Surprise
Wireless charging wattage roughly mirrors the wired hierarchy: Xiaomi 14 leads at 50W wireless, HONOR Magic6 Pro follows at 66W wireless (unusually, HONOR's wireless speed exceeds its own marketing focus on wired charging), and everyone else lands in a tight band between 15W and 23W — the Pixel 8 Pro's 23W wireless is the best of that group, with Galaxy S24, Galaxy A54's absence of wireless charging entirely, Galaxy Z Flip5, and both current iPhones settling for 15W MagSafe or Qi. The Xperia 1 V is the outlier worth flagging: Sony does support Qi wireless charging on the device, but caps it at just 11W and doesn't advertise the figure prominently in its own marketing materials the way every other manufacturer here does — a strange omission for a $1,399 flagship, and one more example of Sony treating charging as an afterthought relative to the camera hardware that's the actual focus of our Xperia 1 V review.
The Charger-in-the-Box Divide
A wattage number only matters if you own a charger capable of delivering it, and this is where the 11 phones split sharply by manufacturer philosophy. Apple, Samsung, and Google have all removed the charging brick from the retail box entirely — Apple starting with the iPhone 12 in 2020, Samsung following with the Galaxy S21 in 2021 — meaning the iPhone 15, iPhone 14, iPhone SE, Galaxy S24, Galaxy A54, Galaxy Z Flip5, and Pixel 8 Pro all ship with a USB-C cable and nothing to plug it into. Nothing Phone (2) follows the same box-minimalist approach. Xiaomi and HONOR, by contrast, remain among the last major flagship makers still bundling their proprietary fast chargers in the box in most markets — which matters more than it sounds, because a generic 20W USB-C charger will not unlock the Xiaomi 14's 90W ceiling or the Magic6 Pro's 80W ceiling; both phones need their maker's own charger (or a small list of certified third-party alternatives) to hit their advertised numbers at all.
Standards Matter as Much as Watts
Not every high number is created equal, because the charging protocol behind it determines real-world compatibility. Samsung, Google, and Apple all rely on the open USB Power Delivery standard (with Samsung and Google adding PPS, Programmable Power Supply, for finer voltage control), meaning a third-party USB-PD charger from any brand will charge those phones at their full rated speed. Xiaomi's HyperCharge and HONOR's SuperCharge are proprietary protocols layered on top of USB-C — they'll still charge on a generic charger, just far slower than advertised, capping out closer to 20-27W until the phone detects its own branded charger and unlocks the higher-wattage handshake. That's a real, easy-to-miss cost of buying into the fastest-charging phones in this lineup: losing or breaking the included charger means losing the headline charging speed too, at least until you track down a replacement from the same manufacturer.
What This Means When You're Actually Shopping
If charging speed genuinely matters to your day-to-day routine — frequent short top-ups between meetings, travel days where a spare 20 minutes at an airport outlet needs to count for something — the Xiaomi 14 and HONOR Magic6 Pro are in a different class from the rest of this lineup, full stop. If it doesn't (overnight charging erases the wattage gap for most owners entirely), the number becomes close to irrelevant, and the phones that top out at 20-25W are giving up essentially nothing in daily practice. Where the gap does matter regardless of habits is emergency top-ups: a dead Xperia 1 V or iPhone needs a genuinely long wait on any charger to reach a useful battery level, while five minutes on a Xiaomi 14 or Magic6 Pro plugged into its own charger recovers a meaningful chunk of a day's use.
Verdict
Charging speed is one of the few specs on this list where the gap between the fastest and slowest phone in our lineup — the Xiaomi 14's 90W against the shared 20W ceiling across the entire iPhone range — isn't a marketing rounding error, it's a genuine 4.5x difference you'll notice every single time you plug in. Whether that difference is worth prioritizing over camera quality, software support, or resale value depends entirely on how often you're charging in a hurry rather than overnight, but it deserves more weight in the buying decision than most spec sheets give it credit for.
