Samsung, Pixel, Motorola: use hidden dumpstate logs to check battery and free space

zdnet.fr (French)

Android phones contain hidden "dumpstate" diagnostic logs that users can access to assess battery health, identify battery-draining apps, and reclaim storage by removing outdated system files. The logs are retrieved via codes such as *#9900# on Samsung devices or *#*#7262626#*#* on others, or through developer options. Users can search entries for charge cycle counts, wakelock activity, and disk write latency to gauge phone performance. Experts advise replacing batteries below 75% health or past 500 cycles, disabling location for apps with wakelocks, and deleting old dump logs that consume gigabytes. The process is free and useful for ordinary users.
