Galaxy S10 wireless chargingGalaxy 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 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:

  1. A phone supports wireless charging.
  2. A wireless charging station.
  3. 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+, S10e, and S10 5G) supports fast wireless charging 2.0,

How to use Galaxy S10 clear view cover (S-View flip cover)?

The definite guide for Galaxy S10 clear view cover (S-View flip cover)

· Leave a Comment

Galaxy S10 clear view cover ( aka Galaxy S10 S-View flip cover) is one of the flagship accessories from Samsung for S10, S10e,  S10+, and S10 5G.

The unique S-View features make the cover stand out, although some original S View features were removed or redesigned.

This Galaxy S10 accessories guide explains the changes, special features, pros and cons of the Galaxy S10 clear view cover. It also shows you how to customize and use the cover, and how to use the always-on display on the clear view cover.

The clear view cover (S View cover) is available for all Galaxy S10 models (S10, S10+, S10e, and S10 5G). The only difference is the cutout and size of the case. In this guide, S10 refers to all of the four S1o models.

What’s new in the Galaxy S10 clear view cover (S-View flip cover)?

Samsung always releases some “official” accessories for their Galaxy phones.

Galaxy S10 clear view cover, aka Galaxy S10 S-View flip cover in some regions, is an evolution of the “S View” cover.

But compared to the Galaxy S9 clear view cover and Galaxy S8 clear view cover, there are some changes:

  • No kickstand. The kickstand in S-View serials covers for S8, S9, Note 8 and Note 9 was removed in S10.
  • Glossy back. The glossy plastic replaces the texture-rich back. It is a fingerprint magnet.
  • Some textures “inside” the front panel. The translucent front panel looks similar to that in S9. But if you stare at it at 90 degrees, you may notice there are some textures. Of course, the texture is inside, not outside of the panel.
  • Lighter and thinner. Because the kickstand was removed, the cover is lighter and thinner compared to that for S9.

On the software side, there are almost no changes.

What are the special features of Galaxy S10 clear view cover (S-View flip cover)?

Galaxy S10 clear view cover shares the similar S-View features as in S9 and S8:

  • Respond to calls, alarms, and events without flipping the cover.
  • Control music on the cover.
  • Read important information including time, date, and battery level on the cover.
  • Auto lock and unlock.
  • Use faceWidgets on the cover.

Please note, there is no separate S-View window as in Galaxy S7 S-View cover.  Since S8, the full front panel is translucent.  The actual display is always on the phone screen.

How to apply and remove the Galaxy S10 clear view cover?

When you apply the Galaxy S10 clear view cover to Galaxy S10, S10e, S10+, and S10 5G, you should fix the top part first. Then finish the bottom part.

When you want to remove the cover (to take out the phone), you should start from the bottom. Once the bottom part of Galaxy S10 is taken out of the cover, you can easily take the phone out.

Do NOT try to start from the top if you want to remove the … Read the rest

How to use Galaxy S10 wireless PowerShare to charge other devices?

· Leave a Comment

You can use Galaxy S10 wireless PowerShare to charge other devices wirelessly.

Galaxy S10 (including Galaxy S10, S10+, S10e, and S10 5G) can be used as a wireless charger to share Galaxy S10 battery with other devices.

This  Galaxy S10 new feature guide explains the details of Galaxy S10 wireless PowerShare feature, how to use it to charge other devices, and answers some questions you may have when using the wireless PowerShare.

What is Galaxy S10 wireless PowerShare?

Wireless charging is not new. Samsung added it as a standard feature since Galaxy S6.

But using the phone as a wireless charger to share the phone battery with other devices is still new.

Huawei named this feature as wireless reverse charging and introduced it in Mate 20 Pro (in 2018) and P30 Pro. Samsung introduced this feature in Galaxy S10 (all 4 models) and named it as wireless PowerShare.

Galaxy S10 wireless PowerShare lets you share the battery juice of Galaxy S1o with other devices that support Qi wireless charging.

Technically, you can still use Galaxy S10 as usual when you share the battery with other devices.

You can even use wireless PowerShare when you are charging Galaxy S10 battery through a USB cable.  For example, you may have only one charger, but you need to charge both the phone and a Galaxy Watch.  In this case, you can connect the wall charger to charge Galaxy S10 and use wireless PowerShare to charge the watch.

In a nutshell, Galaxy S10 wireless PowerShare adds a Qi wireless charger on the back of Galaxy S10. And the charger can use Galaxy S10 battery to charge other devices wirelessly.

Limitations of Galaxy S10 wireless PowerShare

Wireless PowerShare is very convenient, and it works with any devices that support Qi wireless charging.

FYI, most recent mobile devices including iPhone support Qi wireless charging. All Samsung gadgets with wireless charging support Qi wireless.

But wireless PowerShare on Galaxy S10 has some limitations including:

  • Charging speed is slow. There is no fast charging. The maximum charging capacity is 5W. The actual charging speed is substantially lower than this. So, Galaxy S10 wireless PowerShare is mainly designed for accessories like Galaxy Buds, Galaxy Watch. It may be a temporal solution of sharing the battery with other phones. If the other phone also has a USB C port,  you can charge it faster by directly connecting Galaxy S10 to that phone with a USB-C to USB-C cable.
  • You may have to remove the covers or cases for Galaxy S10.  When you charge Galaxy S10 with a wireless charging pad, normally it is not necessary to remove the cover unless the cover is exceptionally thick (or is made of metal). At least, for all Samsung Galaxy S10 official cases (for example, Galaxy S10 LED back cover, Galaxy S10 LED view cover, and Galaxy S10 clear view cover). But when you use wireless PowerShare, you very

How to use Galaxy S10 LED cover (Galaxy S10 LED back cover)?

· 2 Comments

Samsung introduced a new back cover for Galaxy S10, S10+ and S10e: Galaxy S10 LED cover (LED back cover).

The Galaxy S10 LED cover is a back cover with some unique LED features including mood lighting, LED emoticons, Picture cue, and camera timer. The old LED wallet cover is now renamed as Galaxy S10 LED View cover in most regions.

This Galaxy S10 accessories guide explains how to set up and use Galaxy S10 LED cover (Galaxy S10 LED back cover) on Galaxy S10, S10+, and S10e.

Unique features of Galaxy S10 LED cover (Galaxy S10 LED back cover)?

Galaxy S10 LED cover is a new type of official accessories. It is a back cover with some unique LED features.

Compared to other back covers, Galaxy S10 LED back cover has the following special features:

  • Mood lighting.  When Galaxy S10 is facing downwards, a light show is presented with the LEDs.  You can only enable or disable the show, not customize the show.
  • LED notification icons. You will get notification icons on the back when a notification comes. But the LED notification icon only works with some Samsung apps, and you cannot customize the LED icons (as in Galaxy S10 LED View cover).
  • Camera timer. If the timer for the rear camera is turned on, the countdown will be shown on both the screen and the cover.
  • Emoticons for the rear cameras. When you open the camera app, and the rear cameras are active, a LED icon you chose will be shown on the back cover.

Unlike the fabric-like material used in Galaxy S10 LED view cover, the exterior of the Galaxy S10 LED back cover is glossy plastic. Therefore it is a fingerprint magnet.

The Galaxy S10 LED cover provides moderate protection for the glass back of Galaxy S10. The raised edges on the top and bottom (over the screen) offers marginal protection for the screen,  The two side edges of the Galaxy S10 LED back cover for Galaxy S10, and S10+ are lower than the screen due to the curved screen in these two models.

How to set up and customize the Galaxy S10 LED cover (Galaxy S10 LED back cover)?

· 2 Comments

After unboxing Galaxy S10 (S10, S10+, or S10e), you need to understand the Galaxy S10 box contents: what is in the Galaxy S10 box? 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 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.

  1. The Galaxy S10 box
  2. The phone (Galaxy S10, S10+, or S1oe)
  3. A transparent back cover
  4. A USB cable (USB-A to USB-C)
  5. AKG headset (with 3.5mm connector)

  7. USB connector
  8. SIM card tray ejection pin
  9. Quick start guide

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 … Read the rest

Battery Guide for Galaxy S10, S10+, and S10e

· 12 Comments

charge Galaxy S10 battery

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 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.

What are the two ways to charge Galaxy S10 battery?

Galaxy S10 supports charging through the USB-C Port and the wireless charging coil. You may refer to Galaxy S10 layout to check the location of the USB-C port and wireless charging coils.

So, you can charge Galaxy S10 battery in two ways:

  • Through a USB cable (USB charging). Normally, you will use a wall charger. But you can also charge Galaxy S10 battery with a power bank, PC, or another mobile device with USB-C port.
  • Wireless charging.

In Galaxy S10 box, a wall charger is included.

The wireless charging pad is not included in Galaxy S10 box. You may have to buy one.

What are fast charging and fast wireless charging for Galaxy S10, S10+, and s10e?

Galaxy S10, S10+, and 10e support quick charge 2.0 when charging through the USB-C port (USB charging). Of course, this requires a wall charger with quick charge support.

In the Galaxy S10 box, you can find the included 15W wall charger, which is a quick charge 2.0 compliant charger.

Samsung named the fast charge technology as adaptive fast charging. As mentioned in the top 10 disappointing and missing features of Galaxy S10, … Read the rest
