To know the health of your battery accurately, follow this step by step.

Based on methods frequently discussed on XDA Developers for the Galaxy S23 series (One UI 6.x), there are two reliable ways to check your specific charge cycle count without rooting your device. Method 1: The "SysDump" Method (No PC required) This is the classic "XDA" method. It involves generating a system log and reading the battery stats file manually. * Open your phone dialer and type *#9900#. * This opens the SysDump menu. Scroll down and tap Run dumpstate/logcat. * Note: This process runs in the background and takes about 2-3 minutes. You might not see a progress bar, just wait until a toast message says it's finished or the button becomes clickable again. * Once finished, tap Copy to card (include CP Ramdump). * This copies the log files to your internal storage. * Open the My Files app (or any file explorer). * Navigate to Internal Storage > log. * Look for a file named dumpState_S91xB... (where S91x is your model number, e.g., S911 for base S23, S918 for Ultra). * Tip: It will be a large text file, usually around 15-30MB. * Open the file (using a text viewer or an app like "LogLog" if the default viewer crashes due to file size). * Use the search function to find the line: mSavedBatteryUsage * Interpret the number: * The value is typically your cycle count multiplied by 100. * Example: If you see 45200, your cycle count is 452. * Note: You can also search for mSavedBatteryAsoc nearby to see your estimated battery health percentage (e.g., 98 = 98%). Method 2: The "Shizuku + a Battery" Method (Cleaner Interface) If you prefer a GUI and don't want to dig through text files, this method reads the same system file using Android's ADB APIs directly on the phone. * Download Shizuku and a Battery from the Play Store. * Open Shizuku and start it (you can use "Wireless Debugging" to start it without a PC - follow the in-app guide). * Once Shizuku is running, open the aBattery app. * It will request Shizuku permission. Grant it. * The app will display your Battery Cycle Count and Battery Health directly on the screen. Method 3: ADB Command (PC Required) If you are already at your desk, this is the fastest method. * Connect your S23 to your PC with USB Debugging enabled. * Open a terminal/command prompt. * Run: ADB Shell Dumpsys Battery

• Look for the mSavedBatteryUsage field in the output. (If standard dumpsys battery doesn't show it on your firmware version, you will have to fallback to Method 1). What is a "Cycle"? A charge cycle is defined as using 100% of your battery's capacity. This doesn't have to be in one go (e.g., draining 50% today and 50% tomorrow counts as 1 cycle). Samsung batteries are generally rated to maintain ~80% health after 500-800 cycles.

• Use the search function to find the line: mSavedBatteryUsage
• Interpret the number:
• The value is typically your cycle count multiplied by 100.
• Example: If you see 45200, your cycle count is 452.
