Samsung insider teases blazing-fast charging speeds for the Galaxy Note 10+

Samsung insider teases blazing-fast charging speeds for the Galaxy Note 10+ Aside from the screen and battery size differences, the Galaxy Note 10 and Note 10+ will have identical specs, but the more expensive model might also get something no other Samsung phone has: Faster wired and wireless charging. 

Samsung's Galaxy Note 10 and 10+ will arrive on August 23, but the tech giant has already unveiled several new accessories. One of them is a 45-watt USB-C fast charger, which allows you to charge the Note 10 up to 25 watts and the Note 10+ up to 45 watts.

It's available from Samsung directly for $49.99 in either black or white. There is a Samsung-made USB-C cable in the box as well. Technically, it meets Samsung's Super Fast Charging standard and uses a Power Delivery or PD standard. Here's where you can get it, although be warned, shipping times do vary:

  • Samsung 45-Watt USB-C Fast Charger ($49.99; samsung.com)
  • Samsung 45-Watt USB-C Fast Charger ($49.99; amazon.com)
  • Samsung 45-Watt USB-C Fast Charger ($49.99; bestbuy.com)

So what's the tech at play here?

Unlike Anker's PowerPort wall plugs, which use gallium nitride rather than silicon for the chip inside, Samsung is using a PD system in this fast charger. This allows the wall plug to control the charge it delivers to a PD-rated smartphone, which is a safety feature that makes sure it doesn't deliver too much power to the smartphone.

Courant Catch 2 Wireless Charger: Features, pricing and where to buy

Courant Catch 2 Wireless Charger: Features, pricing and where to buy Tired of waking up to a dead phone on a charging pad? Take a look at the Courant Catch 2, out Monday for $175, which aims to solve the dead-zone problem. © Provided by Cable News Network, Inc. Ending the dead zone require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); This is the first pad to feature five wireless charging coils inside, which are slightly overlaid. The result is that you can lay a phone anywhere on the pad and get a charge. In fact, you can charge two Qi-enabled devices on this pad.

For instance, a Galaxy Note 10 will only get up to 25 watts of power, while the Note 10+ gets up to 45 watts. With other devices, the amount of wattage will vary as needed.

Most importantly, this power delivery method is designed for safety. Samsung certainly doesn't want a scenario similar to the Galaxy Note 7 fiasco, when millions of phones were recalled after reports of exploding batteries.

How fast can this charge the Note 10 or 10+?

The Note and Note 10+ have 3500mAh and 4300mAh batteries, respectively. Those are big batteries that can last all day in most cases, thanks to the battery size, along with optimization of the devices by Samsung.

I've been testing the Note 10+ with the 45-watt USB-C charger, and the results have been impressive. With the device entirely dead, at 0%, and plugged into the charger with the included cable, it quickly reached 2% in just over a minute, then 25% in less than nine minutes, and a remarkable 50% in about 20 minutes. It's a high-speed charger that doesn't cause the plug itself to get very hot or even warm to the touch. The phone did get a bit warm -- nothing that would burn your hand, though.

Actually using 45W fast charging on the Galaxy Note 10+ might be a real pain

Actually using 45W fast charging on the Galaxy Note 10+ might be a real pain The Galaxy Note 10 phones come with faster charging speeds than almost all Samsung phones to date. That’s 25W wired charging that proved to be even quicker in real-life tests than 30W charging speeds of the OnePlus 7 Pro. The Note 10+ needed just 65 minutes to reach a full charge using the 25W charger that ships in the box. The Note 10+, however, can also support 45W charging speeds, which means it can recharge even faster than that. To take advantage of the new technology, you’ll have to spend $50 extra on Samsung’s 45W charger. Other USB-C chargers might not work, even if you already own one.

At 32 minutes, the Note 10+ hit 75%, and three minutes later it hit 80%. It seems that the power delivery slowed down as we started to approach 100%. This was most notable at about 75% and resulted in only a few percentage increases over a few minutes. It hit 95% at 50 minutes and a full 100% charge at just over an hour. It hit 99%, nearly a full charge, at just under 60 minutes, and took about three minutes to hit 100%. That's fast, really fast indeed.

It's a seriously impressive charge.

While my full review on the Note 10+ will be arriving soon, for now it's safe to say that Samsung's 45-watt USB-C fast charger is quite impressive. For $49.99, you get a relatively compact charger and a USB-C to USB-C cable. Most importantly, both of these meet the power delivery or PD standard. You get a lot for the money.

It's a bit of a premium price for a charger, but I don't think you'll be disappointed. You'll quickly learn the Note 10+ has a long-lasting battery. This charger is an easy way to get a fast recharge whenever you need it, and it can easily be thrown in a purse or backpack.

Samsung's Galaxy A90 5G delivers specs and super-fast connectivity

Samsung's Galaxy A90 5G delivers specs and super-fast connectivity Being expensive, finicky and hard to find, 5G is still the ultimate early adopter tech. Now, Samsung has brought that incredible speed potential within reach by launching the Galaxy A90 5G. Unlike models including the Galaxy Note 10 Plus 5G or OnePlus 7 Pro 5G, it's one of the few non-flagship 5G phones available, so it might be actually hit a reasonable price point. It would be a stretch, however, to call the A90 5G a mid-tier phone. It's equipped with a Snapdragon 855 processor, up to 8GB of RAM, 128GB of storage and a 6.7-inch, 1080p OLED display, just like we saw from an earlier leak.

Note: The price above reflects the retailers' listed price at the time of publication.

Samsung Galaxy Note 11 could have an in-screen camera .
Samsung may release a phone with an in-screen camera in 2020, but it might not be one of the obvious candidates.That’s according to “industry sources” speaking to The Elec (a South Korean tech news site). The site goes on to speculate that the Samsung Galaxy S11 or Samsung Galaxy Fold 2 might be the first Samsung phone with this feature, but elsewhere we’ve heard that might not be the case.
