Galaxy S10 wireless charging guide

Everything you need to know about wireless charging for Galaxy S10, S10e, S10+, and S10 5G

Galaxy S10 wireless charging allows you to charge Galaxy S10 battery without using a cable on the phone.

But some Galaxy S10 owners still have some questions or concerns on using wireless charging on Galaxy S10 and therefore may haven’t tried this nice feature yet.

This Galaxy S10 how-to guide first explains the confusing terms of wireless charging, fast wireless charging, and fast wireless charging 2.0, and why they are relevant when you charge Galaxy S10 wirelessly. Then I show you how to disable fast wireless charging and answer some questions related to wireless charging on Galaxy S10.

What is wireless charging? What is fast wireless charging? and what is fast charging 2.0?

All smartphones support cable charging. Normally, you can connect the phone to the charger (adapter) through a USB cable (or a proprietary cable) to charge the phone.

The other way to charge a phone battery is wireless charging without using any cables on the phone.

Wireless charging used in the smartphone industry now is all inductive charging, which transfers energy from the charging station to the phone through induction coils.

On the charging station (charging stand, charging base), the induction coil inside the station uses the current from the adapter to create an electromagnetic field. The induction coil in the phone, once paired with the coil in the station, takes power from the electromagnetic field and convert it into charging current for the phone battery.

Wireless charging usually is less efficient than cable charging because energy has to be converted twice: current –> electromagnetic field in the charging station, and electromagnetic field –> current on the phone. So, traditionally, the wireless charging speed is slow. The normal wireless charging can only output charging power up to 5W. Galaxy S6 is the first Samsung phone with wireless charging.

To improve the charging speed, Samsung announced fast wireless charging with Galaxy S7. The maximum charging power output is about 7.5W.

With Galaxy S10, Samsung announced fast wireless charging 2.0, which supports up to a 12W output.

As explained in this guide:

Fast wireless charging 2.0 is based on Qi wireless charging standard set by Wireless Power Consortium. The 2.0 was coined by Samsung to differentiate its implementation from previous fast wireless charging.

So, fast wireless charging 2.0, one of the top 10 new features of Galaxy S10, is not a new industry standard.

The major difference among wireless charging, fast wireless charging, and fast wireless charging 2.0 is the charging power (5W vs 7.5W vs 12W). And therefore, they are backward compatible.

What do you need to use wireless charging for Galaxy S10 battery?

You need 3 components to use wireless charging:

A phone supports wireless charging.
A wireless charging station.
An adapter supplying power to the charging station.

Whether you are using normal wireless charging, fast wireless charging, or fast wireless charging 2.0, is determined by the lowerest one among the 3 components.

For example, since Galaxy S10 (S10, S10+, … Read the rest

Unbox Galaxy S10: understand Galaxy S10 box contents

What is in the Galaxy S10, S10+, or S10e box? How to use them?

simon · 2 Comments

After unboxing Galaxy S10 (S10, S10+, or S10e), you need to understand the Galaxy S10 box contents: what are they? How to use them?

Understanding the items included in the Galaxy S10 box will surely help you use the phone (Galaxy S10, S10+, or S10e) properly and effectively.

This Galaxy S10 how-to guide shows you the package contents of the Galaxy S10 box and explains the usage of the 10 items of Galaxy S10 box contents.

The Galaxy S1o box contents are identical for Galaxy S10, S10+, and S10e, except the phone (and the dimensions of the box). In this page, we will use Galaxy S10 to refer to all these 3 Galaxy S10 phones. You may refer to Galaxy S10 specifications to find the differences among these 3 Galaxy S10 phones.

What are the items of Galaxy S10 box contents?

In different regions, Galaxy S10 distributors may insert some additional promotional items. But the “standard” box contents are standardized by Samsung.

In almost all regions, you can find these 10 common Galaxy S10 box contents as illustrated in the picture below.

The Galaxy S10 box
The phone (Galaxy S10, S10+, or S1oe)
A transparent back cover
A USB cable (USB-A to USB-C)
AKG headset (with 3.5mm connector)
Wall charger (travel adapter)
USB connector
SIM card tray ejection pin
Quick start guide
A leaflet of “How to transfer contents to Galaxy S10”

If you miss any items in the Galaxy S10 box, you may check with the seller.

How to use items of Galaxy S10 box contents?

Of course, each item in the Galaxy S10 box is for you to use and enjoy the phone.

#1. The Galaxy S10 box

The box should be sealed by Samsung or a local distributor.

The seal is to indicate this is an unopened package. If it is a pre-owned S10, it should be stated clearly in the box.

#2. The Phone (Galaxy S10, S10+, or S10e)

The phone is the main and the most expensive item in the Galaxy S10 box.

In most regions, for Galaxy S10, and S10+, a plastic screen protector has been pasted on the screen already. It is not the normal protective film.

If you plan to use a screen protector on Galaxy S10, or S10+, you need to know that many tempered glass screen protectors do NOT work with the in-display fingerprint sensor (see this page), therefore Samsung applied this plastic screen protector for you before you can find a compatible screen protector. You may check this guide on how to use Galaxy S10 in-display fingerprint scanner to unlock Galaxy S10.

For Galaxy S10e, the fingerprint is mounted on the power button, and therefore all screen protector should work with the phone. This is the reason why Samsung does not give a screen protector for Galaxy S10e.

All new Galaxy S10 phones should have about 50-60% battery. You can charge the battery after finishing the setup, or charge the battery before using the phone.

Battery Guide for Galaxy S10, S10+, and S10e

simon · 28 Comments

You need to charge Galaxy S10 battery properly to maximize the battery life without sacrificing your usage.

There are many so-called expert recommendations and rules on how to charge Galaxy S10 battery. Some of them are outdated (e.g., you need to drain Galaxy S10 battery completely every a few weeks). Some are ridiculously wrong (e.g., you should not charge Galaxy S10 battery to full).

This Galaxy S10 how-to guide explains the proper way to charge Galaxy S10 battery with a wall charger (USB charging) or a wireless charger (wireless charging). Quick charge 2.0 and fast wireless charging 2.0 are also discussed.

How long should I charge Galaxy S10 battery the first time?

The old textbook may tell you that you should charge the new battery for at least 6-8 hours for the first time.

This is outdated. It does not apply to the Galaxy S10 battery.

When you charge Galaxy S10 battery the first time, you just need to charge it to “charged.” Then you can disconnect it from the charger (wall charger or wireless charger) and start to use it.

In fact, when Galaxy S10 leaves the factory, the battery was charged to about 60%. You can immediately use the phone when you get it. It is unnecessary to charge a new Galaxy S10 for 6 hours.

In some regions, Samsung does not offer a 1-to-1 exchange for hardware defects. You have to check the phone in the store.

Anyway, there are no special requirements when you charge the Galaxy S10 battery the first time.

Please note, there is no notification LED in Galaxy S10 (including S10, S10+, S10e, and S10 5G) as discussed in this page, you have to wake up the screen to check whether the battery is fully charged or not.
