Question

An AI wrote this Android background sync to keep data fresh, taking a wake lock 'so it doesn't get killed'. It works, but users complain the app destroys their battery overnight and Play Console flags excessive wakeups. What's wrong and how would you fix it?

kotlin

1fun startSync() {2    val wl = powerManager.newWakeLock(PARTIAL_WAKE_LOCK, "app:sync")3    wl.acquire()                       // no timeout, never released4    thread {5        while (true) {6            syncEngine.pull()7            Thread.sleep(60_000)        // every minute, forever8        }9    }10}

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
