Mobile App Performance as a Resource Allocation Problem
Mobile performance rarely collapses because of one catastrophic algorithm. More often, it degrades through a series of small debts: startup code that keeps expanding, background work that wakes radios too often, caches that outlive the screen that created them, and dependencies that quietly increase both memory footprint and initialization cost. The visible symptom may be a slow launch, a hot device, or a process that disappears under pressure, but the root cause is usually the same: too much work happening in the wrong phase of the application lifecycle. Official guidance across Android and iOS converges on one discipline. Keep the critical path short, defer discretionary work, and release resources before the operating system is forced to do it instead.
