Solutions<\/h1>\n        <p class=\"subtitle\">Three common causes: the battery wasn&#8217;t fully charged, Max Mode is drawing extra power, or the battery has naturally degraded after many cycles.<\/p>\n    <\/div>\n\n    <div class=\"answer-card\">\n        <span class=\"label-badge\"><span class=\"dot\"><\/span> Direct answer<\/span>\n        <p>If your Scuba S3 is running for noticeably less time than when new, check these three factors: (1) <strong>Not fully charged<\/strong> \u2014 a partial charge significantly reduces runtime. Charge until the LED shows a full charge indication. (2) <strong>Max Mode enabled<\/strong> \u2014 this mode increases pump motor power for stronger suction but draws more current, reducing runtime noticeably. Switch to a lower-power cleaning mode if runtime is your priority. (3) <strong>Natural battery degradation<\/strong> \u2014 all lithium batteries lose capacity gradually. After 300\u2013500 full cycles, expect 70\u201380% of original capacity. If runtime dropped suddenly (not gradually), revisit causes 1 and 2 first.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-steps\"><\/div>\n        <h2>1. Ensure a Full Charge<\/h2>\n        <p>A partial charge (e.g., charging for only 1\u20132 hours) will give you a fraction of the full runtime. Always charge until the LED indicator shows <strong>solid green<\/strong>, which takes several hours from empty. If the charger was accidentally disconnected or the power went out mid-charge, the battery may read as partially charged in the app but deliver reduced runtime. Fully discharge and recharge once to recalibrate the battery gauge.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-info\"><\/div>\n        <h2>2. Check Cleaning Mode<\/h2>\n        <p>The Scuba S3 has multiple power levels. <strong>Max Mode<\/strong> runs the pump motor at higher RPM for stronger suction, especially effective on heavy debris like leaves and acorns. The trade-off is <strong>20\u201330% shorter runtime<\/strong>. If you typically run Max Mode and notice shorter sessions, switch to <strong>a lower-power cleaning mode<\/strong> for longer coverage. A lower-power mode is ideal for maintenance cleaning of lightly soiled pools and can extend runtime compared to Max Mode.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-info\"><\/div>\n        <h2>3. Battery Cycle Life and Gradual Degradation<\/h2>\n        <p>The S3&#8217;s lithium battery is rated for approximately <strong>300\u2013500 full charge cycles<\/strong> before capacity drops below 80% of the original specification. If your robot is 1\u20132 years old and used daily during pool season, some capacity loss is normal and expected. Gradual decline (a few minutes less each month) indicates normal wear. A <strong>sudden<\/strong> drop (e.g., a sudden 50% or greater drop from one session to the next) is not normal degradation \u2014 it suggests a charging fault, a cell failure, or that you accidentally switched to Max Mode. Check causes 1 and 2 before assuming battery failure.<\/p>\n    <\/div>\n    <div class=\"section-card\">\n        <div class=\"section-icon icon-fix\"><\/div>\n        <h2>Getting a Replacement Battery<\/h2>\n        <p>If you&#8217;ve ruled out partial charging and Max Mode, and the battery runtime is consistently below 50% of the original specification, the battery may need replacement.
