How we handle Mobile
- What these guides cover
- Battery, storage, heat and speed, read from the phone's own built-in logs rather than guessed at.
- Where we stop
- We do not recommend cleaner, booster or battery-saver apps, and we do not cover jailbreaking or rooting.
- Safety line
- A phone too hot to hold comfortably, or a battery that has visibly swollen, is a stop-using-it situation rather than a settings problem.
- What we check against
- Apple and Android platform documentation.
