In its settings, Apple provides a feature called <\/span><b>\u201cBattery Health\u201d<\/b><span style=\"font-weight: 400;\">, which measures the maximum capacity compared with the original capacity. When this percentage drops too low, the overall performance of the device deteriorates.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">The recommended replacement threshold<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">So, <\/span><b>at what percentage should you change your iPhone battery?<\/b><span style=\"font-weight: 400;\"> According to most experts, it\u2019s best to consider replacing it once the capacity drops below <\/span><b>80%<\/b><span style=\"font-weight: 400;\">. Below this level, you quickly notice slowdowns, unexpected restarts and very poor battery life. These drawbacks become annoying even for simple, everyday use.<\/span><\/p>\n<div style=\"padding: 80% 0 0 0; position: relative;\"><iframe style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\" src=\"https:\/\/player.vimeo.com\/video\/1122742246?autoplay=1&amp;loop=1\" frameborder=\"\" allowfullscreen=\"allowfullscreen\"><br \/>\n<\/iframe><\/div>\n<h2><span style=\"font-weight: 400;\">Telltale signs<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It\u2019s not just the number on screen that matters. Some <\/span><b>clear warning signs<\/b><span style=\"font-weight: 400;\"> should alert you. For example, a <\/span><b>phone that runs flat in just a few hours<\/b><span style=\"font-weight: 400;\">, a device that <\/span><b>heats up while charging<\/b><span style=\"font-weight: 400;\">, or being <\/span><b>unable to get through a full day on one charge<\/b><span style=\"font-weight: 400;\">. These issues can appear before the 80% mark, but they become much more common once you go below this threshold.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Why it pays to plan ahead<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It\u2019s a good idea to <\/span><b>check your <a href=\"https:\/\/www.batterylaptop.co.uk\/battery\/mobile\/apple.html\" target=\"_blank\" rel=\"noopener noreferrer\">battery<\/a> health regularly<\/b><span style=\"font-weight: 400;\">. When your iPhone is several years old, it\u2019s wiser to act before it becomes unusable. Replacing the battery early is often more cost-effective than waiting for a complete failure. What\u2019s more, a new battery <\/span><b>gives your phone a real new lease of life<\/b><span style=\"font-weight: 400;\">: it becomes snappier again and battery life returns to a comfortable level.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Conclusion&nbsp;<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In short, the <\/span><b>80%<\/b><span style=\"font-weight: 400;\"> mark remains the <\/span><b>key reference point<\/b><span style=\"font-weight: 400;\"> for knowing when to change your iPhone battery. By planning ahead, you keep a phone that stays <\/span><b>smooth, powerful and long-lasting<\/b><span style=\"font-weight: 400;\">, instead of waiting for a worn-out battery to disrupt your day-to-day life. It\u2019s easy to turn to reliable solutions to replace it with complete peace of mind.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The indicator we forget too often Many users don\u2019t pay attention to the condition of their battery until their iPhone suddenly switches off at 20%.
