This Android phone charges from 0 to 100% in under 10 minutes — and you can’t have it

The charging benchmarks set by Android phones are quite astounding — with some phones being able to charge at 200 watts. If that wasn’t enough, a new Android phone takes it up a notch.

Xiaomi’s newly launched smartphone, the Redmi Note 12 Explorer, brings 210W charging, which is the fastest on any smartphone we’ve seen to date. The proprietary charging tech charges the phone to 66 percent in five minutes and up to 100 percent in about nine minutes. This is extremely impressive considering that the flagship offerings from the likes of Apple and Google take close to two hours for a complete charge.

Power Delivery (PD), which is a common charging standard across USB devices, supports up to 240W of power to charge various gadgets. The standard prescribes 50V at 5A. However, Xiaomi’s charging tech keeps the voltage low at 20W and divides the electricity into three channels of 70W each (20V at 3.5A each). For safety measures, the channels are built to sustain up to 100W of power.

If you’re guessing that Xiaomi uses a massive charger for the same, that’s actually wrong. Thanks to GaN technology, the charger is fairly small in size; it measures 67.3 x 64.3 x 30mm. For those unaware, Gallium Nitride (or GaN) is a material that produces less heat while charging — thus allowing chargers to be more compact, lightweight, and energy-efficient than regular silicon-based chargers.

The supplied USB cable has an E-mark chip, without which the charger cannot attain its full potential. In the case of the Redmi Note 12 Explorer, the charger can spit out 210W power, however, with other devices, it can only do 65W via USB-PD.

While this charging tech is undeniably impressive, it’s unlikely that we will see it in the U.S. anytime soon. We say that because Chinese smartphone brands like Xiaomi do not operate in the U.S. The best we’ve seen for U.S. handsets is the OnePlus 10T, which tops out at 125W charging. That’s still impressive, but it’s a far cry from Xiaomi’s 210W.

The state of other flagship phones — such as the Galaxy S22 Ultra, Pixel 7 Pro, and iPhone 14 Pro Max — is even worse. There isn’t a lot of expectation from U.S. smartphone giants for charging speed, even as brands outside of the U.S. keep pushing the envelope further.

I don’t charge my phone at night because OnePlus broke me (and it’s awesome)
OnePlus 10 Pro charging port.

Here's a fun fact for you. I have absolutely zero idea as to what charge level my phone is at right now. It's on; I can tell you that. But what battery percentage is it at? I couldn't tell you. I couldn't care less and that's because I don't have to. At first, it was scary, but now it's just beautiful.

Here in the U.S., we don't really have to worry about charging phones; we charge them overnight. Maybe we set our phone down on one of the best wireless phone chargers, or we snap on a MagSafe charger (even on Android), or we simply plug the phone in. I used to be one of those people.

Fast charging the OnePlus 10 Pro: SuperVOOC vs. USB-C PD
OnePlus 10 Pro being taken out of a pocket.

Chinese companies have championed the art of charging smartphones at superfast speeds, and that especially holds true for brands under the BBK Electronics umbrella — OnePlus, Oppo, Realme, Vivo, and iQOO. Of these brands, Oppo leads R&D endeavors for itself alongside OnePlus and Realme, which use its proprietary technologies by rebranding them. Among the features that make Oppo one of the best smartphone brands for enthusiasts is fast charging.

At Mobile World Congress 2022, Oppo exhibited its 240-watt charging technology that can charge a smartphone fully in just 10 minutes. While this inexhaustibly fast-charging technology is yet to arrive on a commercial smartphone, Oppo and the companies under it, including OnePlus and Realme, are already launching phones with charging rates up to 150W. OnePlus' recently launched flagship device — the OnePlus 10 Pro — supports up to 80W charging, which the company has claimed can replenish the phone's 5,000mAh battery in just about 30 minutes.

Android 12L is available, but you can’t use it on any tablets
Android 12L changes in action.

Google is finally getting serious about Android tablets with the public release of Android 12L, but the company is still lagging on the effort it seems. Tailored for tablets and foldables to make the most out of their larger screen real estate, the Android 12L update is currently only available for Google’s Pixel phones. No tablet out there, even Samsung’s beastly Snapdragon 8 Gen 1-powered Galaxy Tab S8, is getting it anytime soon.

As per Google’s blog post, the update will arrive for foldables and tablets from Samsung, Lenovo, and Microsoft “starting later this year.” There isn’t a month specified, and the Android 12L rollout will no be uniform, as each company will take time to customize and implement Android 12L in line with their own in-house skin. Google says it will create more new features and experiences for tablets with Android 13, which will arrive later this year.
