Quantified Self: Checking Cycle Counts

Technical Analysis & User Insight:

A battery cycle is one full discharge/charge equivalent. Batteries typically retain 80% capacity after 500-800 cycles. Android 14/15 exposes this metric. On Samsung, it can be found via the SysDump utility (*#9900#) or external tools that read the mSavedBatteryUsage system log.

 

How Old Is Your Battery? Check the Cycle Count

The Problem: You want to buy a used phone or check if yours needs a replacement.

The Fix: Check the "Cycle Count" to see how much life is left.

Step-by-Step Guide:

  1. Pixel: Go to Settings > Battery > Battery Health.

  2. Samsung: Open the Phone dialer and type *#9900#.

  3. Scroll down to open a "Battery Stats" or "SysDump" file (advanced).

  4. Look for "Cycle Count." If it's over 500, you might notice reduced battery life.
