Two ways to charge Galaxy S23 battery
Like other flagship phones, you can charge Galaxy S23 battery with two methods:
- Cable (USB) charging.
- Wireless charging.
Unfortunately, like other flagship phones, Galaxy S23 does not have an “official” charger. Samsung only includes a USB cable in the box. You need to find your own charger.
Each charging method has its own advantages and disadvantages when used to charge Galaxy S23 battery, as summarized in the following table.
|USB cable charging||1. Easy to find a USB charger (adapter).|
2. Usually cheap.
3. May charge Galaxy S23 battery faster.
|1. Occupy the USB-C port.|
2. Old chargers do not stop.
3. Too many low-quality chargers.
|Wireless charging||1. USB-C port available while charging.|
3. Stop charging automatically.
|1. Not cheap.|
2. Relatively slower in charging.
3. Galaxy S23 will be a bit warmer.
Regardless of the charging method, to charge Galaxy S23 battery properly, you need to make sure:
- Use a quality (not necessarily expensive) charger and peripherals (e.g., USB cable).
- Charge only when needed. You can easily check the battery level from the status icons or the battery widget.
- Disconnect the charger only when it is convenient for you.
Charge Galaxy S23 battery with a USB cable
What do you need?
To charge Galaxy S23 battery with a wall charger (USB cable), you need to get two items:
- A USB cable.
- A wall charger or other power source with a USB output.
If the wall charger uses the USB-C output, you can use the USB-C cable in the Galaxy S23 box. If the power source only has USB-A output, you need to get a USB A to USB C cable because Galaxy S23 only has a USB-C port (multipurpose port).
You can also use your PC/laptop or power bank to charge Galaxy S23 battery, although the charging speed is usually slow. Some PCs/laptops even offer a special port for charging your devices through a USB cable. For example, many recent Dell PCs/laptops often have a Powershare USB port, which can be identified by the small battery icon (or a lighting icon) next to the normal USB icon.
Steps of using a USB cable (wall charger) to charge Galaxy S23 battery
To charge Galaxy S23 battery with USB cable charging, you may follow these steps:
- Connect the charger to an electric socket ( and power on the wall charger)
- Connect the USB cable to the wall charger.
- Connect the USB cable to Galaxy S23 USB-C port.
- Wait till Galaxy S23 is fully charged (or to 85% if you set the limit, read on). It is safe to use the phone when it is being charged. But you should avoid heavy games during the charging period. You can press the Side key to check the charging status. If you are using the Galaxy S23 Smart Clear View (S View) Cover, you can also check the charging status in the S View window without opening the case.
- Disconnect the USB cable from Galaxy S23 if it is convenient to do so. It is safe to leave Galaxy S23 on the charger overnight.
- Power off the wall charger if it is convenient to do so.
The charging time depends on the charger, phone load, and ambient temperature. With the Samsung 25W charger, it should take about one hour to fully charge Galaxy S23 battery.
Recommended wall chargers for Galaxy S23
Galaxy S23 supports up to 25W super fast charging. Galaxy S23+ and S23 Ultra support up to 45W super fast charging, as explained in the differences of Galaxy S23, S23+, and S23 Ultra.
However, for Galaxy S23 Ultra, the 45W charger mainly reduces the charging time up to 40-50% of the battery capacity. So, it does not significantly reduce the overall charging time.
Therefore, the Samsung branded 25W charger (including a charging cable) is recommended for Galaxy S23, S23+, and S23 Ultra. It is not necessary to get the 45W charger for Galaxy S23 Ultra unless you often need to charge the battery to less than 60%.
- Rapid Charging. Plug into any standard wall outlet via the include AC adapter. The Super Fast charger delivers up to 3 Amp to give your phone power at a much faster rate than your standard 1A or 700mA charger..Compatible devices:Smart Phones;Headphones; smartwatches.Special Feature:Rapid Charging;Wide Compatibility
- Compatible with various devices. Wall Charger does the job for Android devices as well as devices that run different operating systems. For this Wall Charger, the size of your devices isn’t a problem; from earbuds to laptops, take advantage of an ideal charging time for your devices at speeds they can manage to handle.
- Enjoy the flexibility of the USB Type-C. Enjoy the flexibility enabled by USB-C compatible cables. You can alternate the types of cables to charge a variety of mobile devices that you own. Just plug in a cable – there’s no need to change the adapter plugged into your wall outlet.
- Input Voltage 100-240
If you need a USB C cable, you should try to get one from a trusted brand. Because all Galaxy S23 models support USB C 3.2 for data transfer, you should get a USB C cable that supports USB 3.2 or 3.1 at least. FYI, most USB C cables, especially those marked as charging cable (including 100W or 140W) in the market only supports USB 2.0 for data transfer.
So, if you also plan to use the spare cable for data transfer, you should get one with USB 3.1/3.2 support, for example, this one.
Charge Galaxy S23 battery with a wireless charger
What do you need?
To charge Galaxy S23 battery with a wireless charger, you need to get the following:
- A wireless charging pad.
- The power adapter for the wireless charging pad.
Although most wireless charging pad is powered by normal USB wall charger, you should try to use the “bundled” power adapter for the wireless charging pad.
Steps of using a wireless charger to charge Galaxy S23 battery
You can charge Galaxy S23 battery through a wireless charger by following these steps:
- Connect the power adapter (or USB wall charger) to the wireless charging pad. Most wireless chargers come with a wireless charging pad and a detachable power adapter.
- Power on the wireless charging pad. You can connect the power adapter or wall charger to an electric socket to power on the wireless charging pad. Most wireless chargers have some LED lights to light up when powered on.
- Place Galaxy S23 in the wireless charging pad. You should try to place the wireless charging coil region (see Galaxy S23 layout) near the centre of the charging pad, as illustrated in the picture below.
- Wait till Galaxy S23 is fully charged (or to 85% if you set the limit). Normally, the wireless charging pad has an LED indicator for the charging status (charging or charged). The wireless charger will stop charging the phone once it is fully charged.
- Remove Galaxy S23 from the charging pad if it is convenient to do so.
Please note that some bulky cases/covers may affect wireless charging. But most of the official Samsung-branded covers (e.g., Galaxy S23 Smart Clear View Cover/S View Cover) do not suffer from this issue.
Recommended wireless charger for Galaxy S23
The quality of wireless chargers is extremely important. Never use wireless chargers from unknown brands.
All three Galaxy S23 models support up to 15W fast wireless charging. So, you should get a wireless charger that supports 15W (or 9W at least) wireless charging.
Normally, we recommend Samsug’s 15W fast wireless charger like this one:
- SUPER FAST WIRELESS CHARGING: Get the charge you need quickly, thanks to up to 15W of Fast Charging support; This boost of battery is compatible with USB PD and Adaptive Fast Charging travel adapters for an easy pick-me-up*
- EASE OF USE & MULTI DEVICE CHARGING: Simultaneously power up your favorite pair of devices to enjoy together — whether that’s your phone and Galaxy Watch or your Galaxy Watch and earbuds

- LED INDICATOR: LED light tells you the charging status of your device with different colors: red for charging, flashing red for charging error, and green for fully charged; When it’s time for lights out, you can dim it to not disturb your sleep*****
This guide gives details on how to choose a compatible wireless charger for Galaxy S23.
How to disable fast charging and fast wireless charging to extend Galaxy S23 battery life?
Fast charging is a nice feature if you need to charge Galaxy S23 battery quickly. But it may cause slightly more wear and tear on the battery.
So, some Galaxy S23 owners may want to disable fast charging (and fast wireless charging) to extend the battery life span.
When do you need to disable fast charging (or fast wireless charging) for Galaxy S23?
If you are a light user and only need to charge Galaxy S23 battery every night, you may consider disabling fast charging and fast wireless charging. This potentially reduces the stress on the battery and, therefore, may extend the battery life noticeably.
Normally, you may also consider setting the battery charging limit to 85% (Protect Battery), which can further extend the battery life considerably.
How to enable and disable fast charging (or fast wireless charging) on Galaxy S23?
You can enable or disable fast charging and fast wireless charging from Galaxy S23 Settings.
As shown in the screenshot below, tap Battery and device care.
On the Device care page, as shown in the screenshot above, tap Battery to manage and customize battery settings.
Please note you can also manage and tweak storage and memory usage and settings in Device care.
On the Battery page, as shown in the screenshot below, you can:
- Check battery usage of charging status.
- Enable power saving mode.
- Set up and tweak background battery usage limits.
- Battery usage details.
- Enable/disable wireless power sharing.
- Adjust advanced battery settings (more battery settings).
Fast charging and fast wireless charging are under more battery settings. So tap More battery settings, as shown in the screen below.
On the More battery settings page, as shown in the screenshot above, you can find the switch to enable/disable fast wireless charging, fast wireless charging and Protect battery.
You can use the switch to enable or disable these features accordingly.
How to enable Protect Battery to extend Galaxy S23 battery life?
Protect Battery was first introduced in Galaxy S22. It set the charging limit to 85% of the battery capacity.
In other words, regardless of the charging method, once the battery level reaches 85%, Galaxy S23 will stop charging Galaxy S23 battery until you reconnect the charger.
When you charge Galaxy S23 battery, the “resistance” gradually becomes larger after the battery level reaches about 80%. So, the charging speed always gradually slows down. At the same time, the wear of the battery increases.
Therefore, limiting the battery charging limit to 85% of the battery capacity may significantly reduce the wear on Galaxy S23 battery and thus extend the battery life span considerably.
If the 85% battery is enough for you or if you can access the charge easily, then you may consider enabling Protect battery on Galaxy S23 to improve the health of the Galaxy S23 battery.
You can enable Protect battery on Galaxy S23 from two different locations:
- From Settings — Battery and device care — Battery — More battery settings — Protect battery, as shown earlier.
- From the Quick Settings panel and use the quick setting button.
As shown in the screenshot below, you can tap the Protect Battery icon to enable or disable Protect battery instantly.
