#2. Improved design

In Galaxy S20, the new S View window is not on the edge of the front piece. Instead, it is embedded inside … Read the rest

How to set battery limit for Wireless PowerShare on Galaxy S20, Note 10, and S10?

By simon Leave a Comment Last Modified: December 3, 2020 · Published on: March 16, 2020

Wireless PowerShare is a convenient feature allowing you to charge accessories with Galaxy S20 battery.

When the feature was first introduced in Galaxy S10, the battery limit for wireless Powershare is fixed at 30% (of the phone battery). In Android 10 update for Galaxy S10 and Note 10, Samsung allows owners to raise the battery limit for Wireless PowerShare.

Galaxy S20 also allows you to adjust the battery limit for Wireless PowerShare. And it works identically to Galaxy S10 and Note 10.

This Galaxy S20 guide shows you how to adjust the battery limit for Wireless PowerShare on Galaxy S20, S10, and Note 10. Some questions on setting the battery limit for Wireless PowerShare are also answered.

What is Wireless PowerShare on Galaxy S20?

Wireless PowerShare turns your Galaxy S20 into a Qi-wireless charger. So, you can use your Galaxy S20 to charge accessories and even other phones that support wireless charging.

The typical usage of Wireless PowerShare is to charge your smartwatch, earbuds (e.g., Samsung Galaxy Buds, Galaxy Buds+) with your Galaxy S20’s battery. You can use it to charge other phones. But the speed is not so fast (it is the standard wireless charging. No fast wireless charging.)

Samsung first introduced this feature with Galaxy S10. It is one of a few well-received new features in Galaxy S10. Galaxy Note 10 and Galaxy S20 implemented the wireless Powershare similarly.

A detailed guide on how to use Wireless PowerShare can be found here. It applies to all Samsung devices supporting Wireless PowerShare.

The original implementation of the Wireless PowerShare in Galaxy S10 and Note 10 hardcoded a battery limit of 30%. Wireless Powershare will stop automatically if the phone battery is lower than 30% of its full capacity.

Because the phone battery drains faster (most of us can “feel” it) when the battery level is low, some owners want to reserve more battery, especially when charging other phones. The 30% limit may be too low for them.

So, in Android 10 update, Samsung added the option for you to set battery limit for Wireless PowerShare on Galaxy S10 and Galaxy Note 10. Galaxy S20 has this feature from day 1.

Please note some official Samsung Galaxy S20 cases, like Galaxy S20 LED View Cover, Galaxy S20 Clear View /S View Cover, and Galaxy S20 LED back cover, may affect wireless … Read the rest

The guide also answers questions you may have on charging Galaxy S20 battery.

Charging Galaxy S20 battery is identical on Galaxy S20, S20+, and S20 Ultra. The only difference is that Galaxy S20 Ultra supports 45W super fast-charging; while Galaxy S20 and S20+ only support up to 25W.

Do you need to charge Galaxy S20 battery for 8 hours for the first time?

No, it is unnecessary to charge Galaxy S20 battery for 8 hours for the first time.

You can disconnect the charger once the battery is fully charged.

The old textbook may teach you to charge the new battery for 8 hours. It is outdated.

When you open the Galaxy S20 box, the battery level on your Galaxy S20 should be normally around 50-60%. You can use the phone immediately.

In some regions, Samsung does not offer a 1-to-1 exchange. You have to power on the phone on the spot to check the phone before you leave the counter.

Two ways to charge Galaxy S20 battery

You can charge Galaxy S20 battery in two ways:

USB charging. You can charge Galaxy S20 with a USB cable, which connects to a USB power source (normally, a wall charger).
Wireless charging. You can put Galaxy S20 on a wireless charging pad to charge the battery. You can use the USB port to connect other devices, e.g., a USB thumb drive.

In Galaxy S20 box, a 25W charger and a USB-C cable are included. You can use them to charge Galaxy S20 battery.

Of course, you can use other wall chargers, power banks, or USB hub to charge Galaxy S20. But the charging speed may be affected. For example, if you use a USB port on your PC or laptop to charge Galaxy S20, you may find it is too slow.

What is fast charging, super-fast charging, fast wireless charging and fast wireless charging 2.0?

By simon 2 Comments Last Modified: December 3, 2020 · Published on: March 1, 2020

Samsung bragged a lot about fast charging and super-fast charging for Galaxy S20, S20+, and S20 Ultra.

But these are not industrial standards, although there are some industrial standards behind.

So, as an owner of Galaxy S20, you may be confused with the Qualcomm quick charge (QC) or USB power delivery.

This Galaxy S20 guide explains the meaning of fast charging, adaptive fast charge, super-fast charging, fast wireless charging, and fast wireless charging 2.0, and the link to industrial standards.

What are fast charging, adaptive fast charging, and super-fast charging on Galaxy S20?

Before you charge Galaxy S20 battery, you may need to understand some jargons used on “fast” charging.

The old USB charger usually charges up to 5W (5V, 1A). The fast USB charging usually refers to charging up to 10W (5V, 2A).

But Samsung coined “adaptive fast charging” for charging up to 15W (9V, 1.67A) since Galaxy S6. Up to Galaxy S10, the 15W adaptive fast charger had been bundled with Galaxy S and Note devices.

Adaptive fast charging supports both 10W USB fast charging, and 15W proprietary fast charging. The 15W fast charging can be activated only when the battery level is lower than about 60%.

Samsung minted “super-fast charging” when Galaxy Note and Note 10+ were announced last year. It refers to up to 25W charging for Galaxy Note 10, and up to 45W for Galaxy Note 10+.

Galaxy S20 and Galaxy S20+ support super-fast charging up to 25W, and Galaxy S20 Ultra up to 45W, as explained in the differences among Galaxy S20 models.

Adaptive fast charging and super-fast charging were not industrial standards. Samsung minted them.

The industrial standards related to USB charging for phones have two different sets:

Qualcomm Quick Charge (QC). All Samsung devices, including Galaxy S20, only support QC 2.0. FYI, the latest version is QC4+. Probably due to licensing cost for Samsung’s Exynos chips used in some regions, Samsung chose not to support QC 3.0 or QC4 on all their phones including those with Snapdragon chips.
USB Power Delivery (PD). USB PD became popular with the wide adoption of USB-C, although USB PD does not rely on USB-C. Also, there are no licencing fees involved. Samsung does not explicitly state the support of USB PD. But Galaxy S20 did get the fast USB charger certificate from

So, this guide applies to the layout of Galaxy S10, S20+, and S20 Ultra. In the text, we use the Galaxy S20 layout refers to all of these 3 models.

Why do you need to know about Galaxy S20 layout?

After unboxing Galaxy S20, the first thing you want to do is powering on the phone.

But where is the power button? If you are an owner of Galaxy Note 10 (or Note 10+), then you may find the power button (side key) is not relocated back to the right.

If you want to record an audio clip (especially in the interview mode), you probably need to know the location of the two microphones.

If you want to use NFC, use wireless charging, or use wireless PowerShare, you need to know the location of antennas and coils.

If you are new to the in-display fingerprint sensor, you need to know where to put your fingers on.

Anyway, all Galaxy S20 owners need to know the layout of Galaxy S20, S20+, and S20 Ultra so that you can use the phone effectively.

Galaxy S20 layout

In the picture below, 15 items of the Galaxy S20 layout are illustrated.

Unbox Galaxy S20: Understand Items in Galaxy S20 Box

By simon Leave a Comment Last Modified: September 8, 2020 · Published on: February 26, 2020

Once you unbox Galaxy S20, you need to understand the items in the Galaxy S20 box and know how to use them.

This Galaxy S20 guide illustrates the contents in Galaxy S20 box and explains to you how to use them (including the phone, wall charger, clear back cover, USB cable, USB-C headset with additional ear tips, and SIM card tray ejection pin).

The contents (items) in Galaxy S20, S20+, and S20 Ultra are almost identical except the phone, although there are significant differences among these 3 models.

So, in this guide, Galaxy S20 refers to all of these 3 models: Galaxy S20, S20+, and S20 Ultra.

What is included in the Galaxy S20 box?

As shown in the picture below, after unboxing Galaxy S20, there are at least following 7 items in the Galaxy S20 box:

The phone.
Clear cover.
USB-C cable.
Wall charger.
USB-C (AKG) headset.
Additional ear tips (small and large).
SIM card tray ejection pin.

Of course, you can also find some leaflets and inserts depending on the region/distributor.

Among the leaflets, you can find the quick start guide and safety information sheet.

In a few regions, a USB adapter may be included in the box.

Understand the contents in Galaxy S20 box

Now, let’s go through the items in the Galaxy S20 box one by one.

#1. The phone: Galaxy S20, S20+, or Galaxy S20 Ultra

Of course, this is the main and the most expensive item in the box. Others are just “accessories”.

In many regions, Samsung does not offer a one-for-one exchange. If you find any problems after leaving the counter, you need to claim the warranty.

So, you should check the phone on the spot. If there are any issues, you can choose not to accept the item.

Because of the ultrasonic in-display fingerprint reader which is one of the worst “innovations”, some tempered glass screen protectors will not work with the fingerprint sensor.

In most regions, Samsung pasted (pre-installed) a plastic screen protector on the screen already. The quality of the screen protector is actually quite good. And most importantly, it works nicely with the in-display fingerprint reader.

If you need a screen protector, you should not remove it before you get a new one. If you try to re-apply the screen protector, very likely, you will get many bubbles.
