How to charge Samsung Galaxy Note 9’s S pen


Samsung Galaxy Note 9, like every Galaxy Note device before it, has the particular S Pen stylus, which separates it from most other smartphones. What’s more, the newest S Pen has been upgraded in a big way. It’s no longer a mere notetaking accessory, but a full-fledged remote control for your Note 9.


A ton of new tricks has been added to the S Pen. You can use it as a remote camera shutter, a presentation remote with Samsung’s Dex, and for music controls and more. It means that the S Pen should be connected to your Note 9 and will drain more power. Samsung put forward a clever solution to that: using supercapacitors. Sticking the S Pen into the phone for 40 seconds will give it enough juice for 30 minutes of use, so battery life should no longer be a worry. But how exactly does the technology work?

What is Supercapacitors?

Supercapacitors (or ultracapacitors) store energy and, in part, are the opposite of batteries. Batteries can hold a decent amount of energy but take a long time to charge. Supercapacitors charge so fast it seems instantaneous, taking just seconds or minutes rather than hours. But they hold only a tiny amount of energy. Imagine getting shocked by static electricity — it happens very fast, but there’s only a little bit of shock.

Supercapacitors work like normal capacitors, by accumulating electrical charge on their surface, but at a bigger scale. They consist of two metal plates, one with a positive charge and one with a negative charge. These metal plates are surrounded by a solution of positive and negative ions, which build upon the plates during charging to deliver electricity. That means that the amount of energy supercapacitors hold is very dependent on how big the plates are — which isn’t very convenient when we want our electronics to be small.  But they do have one other big advantage: You can charge for thousands and thousands of cycles without degrading the way lithium-ion batteries do.

The Supercapacitors is perfect for S Pen. The S Pen comes with a Note phone, so the rapid-charge feature makes sense. And it won’t degrade after numerous charging. If we just take consideration of the battery life, S Pen can even live longer than your Note 9. And it’ll still work as a regular stylus even when the pen dies. Users will no need to think about managing battery life on the pen, which is smart.
