Review
Performance, battery, and network review
We measure cold start, jank on mid-range devices, and how chatty the app is when the radio should be asleep.
Typical duration: 3–7 working days
Johor Bahru users move between office Wi-Fi, home fibre, and congested mobile data on the Causeway and in town. An app that feels finished on a flagship in the office can still drain a mid-range Android on the commute. We run the build on a small device set that includes at least one mid-range Android and a current iPhone, then we watch startup, first meaningful screen, scroll, and background wake-ups.
We also look at image weight, uncached lists, polling, and location listeners that never quite let go. The write-up is a set of observations you can hand to engineering, not a lab score that nobody can reproduce.
