How we pick the best phone under ₹20,000
At this price point, the biggest differentiator is thermal management. Many phones in the ₹20,000 segment score well in 5-minute benchmarks but throttle significantly during gaming or extended video recording. Our thermal score measures sustained performance under a 30-minute load — the real number that matters.
Battery capacity numbers are misleading. A 5000mAh battery with a power-hungry chipset can last less than a 4500mAh cell paired to an efficient processor. We score screen-on time in mixed usage, not mAh.
Software support is the hidden long-term cost. A phone with only 2 years of updates will be insecure and slower by year 3. Our picks weight brands that commit to extended update windows.
