In a market long defined by the race for processing power and camera megapixels, Oppo has placed a quieter bet: that what many people truly want is simply for their phone to last. The A7 Pro Max, arriving in Europe through Austria at €599, carries a 10,000 mAh battery — the largest Oppo has ever built — paired with capable but unspectacular mid-range hardware. It is a device that asks whether endurance, not excellence, might be the more honest measure of a tool we carry through every waking hour.
