The 658 mAh battery is significantly larger than most smartwatches in this price range — about 2.4× the Active 2's 270 mAh. The 64-hour continuous GPS makes it genuinely viable for multi-day trail runs and unsupported ultra-marathons. A separate GPS-with-music figure of 22 hours means you can navigate and listen offline without cutting battery life drastically.

Built-in GPS with 5 satellite systems (GPS, GLONASS, GALILEO, QZSS, and BeiDou) for fast lock and accurate positioning in any terrain. The Active Max supports offline maps — terrain maps, ski resort maps, and contour maps — all stored in the 4 GB on-watch storage, so navigation works without a phone signal.

Live turn-by-turn voice directions work across all major outdoor sports modes. The barometric altimeter adds altitude data to GPS tracks, giving hikers and skiers accurate elevation profiles that GPS alone can't provide. Smart Trajectory Correction improves running route accuracy on tracks and winding paths.

The Amazfit Active Max at ₹15,999 is a compelling step up within the Active family. The 25-day battery alone separates it from most competitors at this price — the 658 mAh cell means you can genuinely forget about charging for weeks at a time, and the 64-hour GPS endurance makes it a serious option for ultramarathon athletes and long-distance hikers.

The headline display upgrade — 1.5 inches at 3,000 nits — makes outdoor readability effortless and the larger canvas makes coaching prompts, maps, and stats easier to scan mid-workout. The addition of BioCharge™ energy monitoring fills a gap the Active 2 left open: a single, always-updated number that tells you whether to push or recover, factoring in activity, stress, and sleep simultaneously.

The 4 GB on-watch storage is genuinely useful. Most smartwatches in this range are map-browsers only; the Active Max lets you actually leave your phone at home. Podcasts and offline maps stored together, accessible even in the mountains with no signal, changes what this watch can do for a weekend trail runner or bikepacker.

Choose the Active Max if you want the longest battery in the Amazfit Active lineup, serious GPS endurance, BioCharge readiness tracking, 4 GB on-watch storage, and the barometer + temperature sensors. Consider the Active 2 if you prefer a compact round design and a ₹6,000 lower price and don't need the extra battery days or storage.
