ZDNET’s key takeaways
- I examined three fast-charging smartphones.
- I used OEM and third-party chargers.
- Two telephones beat their rated speeds; one fell brief.
Charging pace is a type of numbers that advertising and marketing individuals like to toss round. That is very true in the case of OnePlus. It may be a throwaway line, however when new telephones launch, you will usually hear about marketed charging speeds. From 25 watts all the best way as much as 120 watts, how briskly your telephone can cost may matter to you.
It additionally issues how briskly the plug you purchase is, too, as a result of two of our three rivals do not include a wall plug.
Additionally: I cracked open a ‘1,000W’ portable charger after it failed me in minutes – and wished I hadn’t
It is a little-known undeniable fact that, simply because a telephone can cost at 60W, that will not be the charging pace for many of its cost time. It isn’t even shut. However you could be questioning how shut it will get. To search out out, I charged up a Samsung Galaxy S26 Ultraan iPhone 17 Pro Maxand a OnePlus 15 and recorded the outcomes. I realized a couple of issues and uncovered a couple of surprises alongside the best way.
The candidates
The iPhone 17 Professional Max and the Samsung Galaxy S26 Extremely each characterize the flagships of the 2 main telephone makers within the US. Likelihood is, should you’re studying this, you personal a telephone with the phrase Samsung or a bitten apple on the again of it. The OnePlus 15 stands tall as what ought to be potential within the US, however simply is not. At the very least it ought to characterize that, however we’ll focus on that in a bit.
Additionally: I’ve used adaptive chargers with my iPhone and Android for a year – but should you?
The iPhone 17 Professional Max ships with a 5,088 mAh lithium-ion battery able to 40W of wired charging. The Samsung Galaxy S26 Extremely ships with a 5,000 mAh lithium-ion battery that expenses at 60W. Lastly, the OnePlus 15 ships with a 7,300 mAh silicon carbon battery with an marketed charging pace of 120W. I phrased that final one very rigorously, as you will quickly be taught.
Charging plugs from OnePlus, Anker, Apple, and Samsung

The OnePlus 15 ships with an influence plug and cable, whereas the opposite two ship solely with a cable. Apple sells a 40 W Dynamic Power adapter for $39. Samsung sells a 45W travel adapter with a magnetic wireless charging puck included for $71.25. But when you are going to purchase a charger anyway, why not strive a third-party possibility? I went with Anker on this case because the model is synonymous with charging. I grabbed an Anker Prime GaN charger and Anker bio cable for $59.99 and $21.83, respectively, on Amazon.
Additionally: I spent 2 years charging my phone exactly how Apple suggests – here’s where it’s at now
To check charging speeds, I picked up a Mecheer power meter that shows how a lot energy is flowing by the outlet in actual time. For every telephone, I ran the take a look at twice — as soon as with the OEM cable and plug and the second time with my Anker setup. Here is what occurred.
The outcomes
Of the information I collected, a few issues stand out. First, OnePlus’ charger is not even near its marketed 120W pace. Actually, it spent its complete cost time within the 20% to 40% vary, maxing out at simply 46W on its homegrown charger. The Anker pairing charged the OnePlus and Samsung telephones quicker than their very own chargers, which I discover to be merely humorous.
Additionally: I cracked open cheap charging gadgets from Temu – and it was worse than I expected
In one other attention-grabbing bit, the S26 Extremely, which is rated at 60W, truly peaked at 61W. Equally, the iPhone, which is rated at a most of 40W, spent its first 5 minutes exceeding that mark.

Complete cost instances ended up like this:
Charging instances for the telephones

Samsung was surprisingly agile, going from useless to totally loaded in beneath an hour. OnePlus stayed in the course of the pack with simply over an hour, and the iPhone introduced up the rear with over 90 minutes for a full top-off. That is why I often cost my iPhone in a single day. However amongst these outcomes, I discovered Samsung probably the most nice shock and the OnePlus 15 the largest disappointment.
Additionally: A common charging habit was quietly killing my iPhone’s battery – here’s the fix
OnePlus’ days of charging dominance appear to be over, and that is frankly a disgrace.

Listed below are some enjoyable info for you. If it’s important to purchase a charger, go forward and get a third-party possibility. A Samsung telephone expenses at about 3% per minute for the primary 60% and solely slows down after that. The opposite two telephones go at about 2% per minute for the primary 50%.

The decision
So, on the finish of the day, charging speeds are largely overrated. Apart from OnePlus, which sat beneath 40% of its marketed charging threshold all the time, the opposite two telephones spent most of their time hovering between 20% and 60% of capability. I discover this neither shocking nor, to say the least, extremely disingenuous.
Additionally: I used the ‘Plus Five’ rule to fix my iPhone’s slow wireless charging – here’s how it works
It is virtually to the purpose the place I would slightly simply not know what the charging capabilities are — I would slightly not know than know one thing incorrect. However that is me.
