Battery Health Samsung
To check the battery health on a Samsung phone, you can use the Samsung Members app or via third-party apps. Samsung Members is pre-installed on most Samsung phones, or you can download it from the Galaxy Store or Google Play.
1. Via the Samsung Members app (recommended way)
- Open Samsung Members.
- Tap Support at the bottom of the app.
- Select Phone Diagnostics.
- Tap Test All.
- Here you will see information about your Samsung's battery health, which may be displayed as "Good", "Moderate", or "Poor".
2. Through third-party apps
If you want more detailed information, you can download apps like AccuBattery, DevCheck, or CPU-Z from Google Play. These apps can provide an estimate of the remaining battery capacity in percent.
If the battery health is poor, it may be time to replace the battery.
>80% battery health on used Samsung
When you buy one used Samsung From reNewed you can be sure that the battery is tested and working properly. All our devices undergo thorough checks where we test the battery's capacity and performance.
If necessary, we will replace the battery so that you get a reliable device with a long lifespan. You always buy a phone with at least 80% battery health.
Optimize battery via settings
- Go to Settings.
- Select Battery and device care.
- Tryck pa Battery.
- Here you'll see battery usage and optimization options, but no direct battery health.
Detect abnormal battery behavior
- Open The Phone app.
- Wrap up * # # 0228 and press Call me.
- A diagnostics window opens with details about the battery, including voltage and capacity.
This method doesn't typically provide information about battery health, but it can tell you if your battery is behaving abnormally. If you see any of these issues, it may be time to replace your battery, or at least keep an eye on it to see if the problems get worse over time.
Low voltage (Voltage)
Normally, the battery voltage is around 3,7V to 4,4V depending on the charge level. If it is very low (e.g. below 3,5V at 50% battery), it may indicate that the battery is worn out and not holding a charge properly.
Sudden voltage drops
If you see the voltage dropping quickly even though your phone isn't being used much, your battery may be worn out. For example, if you have a 50% charge and the voltage suddenly jumps from 3,9V to 3,3V, it could be a sign that the cells in the battery are weak.
Incorrect capacity information
If the reported mAh capacity is much lower than the official battery capacity, it may mean that the battery has lost a lot of its lifespan. For example, if you have a phone with a 5000 mAh battery, but the test shows that the maximum capacity is below 3000 mAh, it means that the battery has significantly worn out.
Inconsistent temperature
A normal battery stays between 25-40°C during normal use. If the battery appears very hot (>50°C) without heavy load, it may be a sign of a defective or swollen battery.
Sudden shutdowns despite high battery level
If your phone unexpectedly shuts down at, say, 30% and shows "0%" when you turn it back on, the battery may have worn cells or incorrect calibration.
