How to check, repair or replace a Samsung Galaxy device battery
If your Galaxy device shows signs of battery damage or reduced performance, it may be time for inspection or replacement at a Samsung Service Centre. Find out what symptoms suggest a battery replacement, how to run a quick check, when to replace it, and why it’s best to visit a Samsung Service Centre for repair.
When to check your Galaxy battery
If your Galaxy device frequently shuts down unexpectedly, drains quickly, or fails to charge properly, the battery may have reached its replacement point.
However, these symptoms can also result from background apps or system overload. For an accurate diagnosis, we recommend visiting a Samsung Service Centre for professional inspection. Use Phone diagnostics tool in Samsung Members app to check for battery status.
Causes of fast battery drain
Battery consumption may vary depending on your usage habits, network environment, and active features. Check the following before considering replacement.
- After buying a new device
During the initial setup, account syncing, or data restoration, temporary battery usage may increase. The system will stabilise after a short time.
- Unstable network conditions
In areas with weak or unstable signal (for example, in subways or buildings), the device may continuously search for a connection, increasing battery usage.
- Multiple apps or features running simultaneously
Keeping unused apps running in the background or leaving Wi-Fi, Bluetooth, GPS, or auto-sync on at all times can drain the battery faster.
- High brightness or intensive use
Maintaining a high screen brightness or using demanding apps (such as gaming or video streaming) consumes more power.
To reduce consumption, close unused apps, enable Power saving mode, adjust the screen brightness, and turn off unused features (Wi-Fi, Bluetooth, GPS, auto-sync).
You can also use Battery and device care to automatically optimise performance.

Causes of battery overheating when the device is not in use
Even when your device is not in use, it may feel hot due to various factors. In most cases, the heat comes from hardware components such as the chipset rather than the battery itself.
This can happen when certain apps continue running in the background or when automatic syncing consumes significant system resources. During wireless charging, heat may also occur if metallic objects such as coins, keys, or metal cases are caught between the device and the charger coil.
If your Galaxy device feels hot, try optimising it using the Battery and device care feature and set rarely used apps to power saving mode. When charging wirelessly, make sure to remove any metallic attachments or foreign objects before charging.
If you suspect an issue with the battery itself, refer to the next section for instructions on checking your battery status. If the issue continues, visit a Samsung Service Centre for a professional inspection.

How to check battery status
You can easily diagnose your Galaxy device’s battery status using the Samsung Members app.
From the Support tab, run the Phone diagnostics feature to check your battery’s life span and overall health, allowing you to determine whether replacement or maintenance is needed.
Since you can check the basic performance status without any special equipment or visiting a Samsung Service Centre, it is useful for regular self-inspection.

When to consider replacing the battery
In general, the lithium-ion batteries may gradually lose performance over time. The following changes are some examples of signs that the battery may be nearing the end of its life span. If these symptoms occur, it is recommended to check the battery condition and consider a replacement.
- The battery drains quickly after charging
- The device turns off unexpectedly in cold environments or during winter

Expected time and preparation for Galaxy battery replacement
Estimated service time
On average, replacing a Galaxy device battery may take about one hour. The actual time may vary depending on the model, inspection items, and parts availability.
Preparation before battery replacement
Before proceeding with the replacement, it is important to make a few preparations in advance. First, back up all data on your Galaxy device to prevent unexpected data loss during repair. You can easily save personal data such as photos, contacts, and app information using Samsung Cloud, or the Smart Switch PC program or mobile app.
In addition, since the device needs to be unlocked for Samsung Service Centres to perform inspection and testing, it is recommended to disable any fingerprint, PIN, or pattern lock prior to the repair.
Making these preparations in advance will help ensure that the battery repair and replacement process proceeds more smoothly and efficiently.
