But is it always worth using, even when your battery is full? In this article, we will dive into how Low Power Mode works, its impact on your iPhone\u2019s performance, and when it makes sense to turn it on or off. Here\u2019s what happens when you enable Low Power Mode on your iPhone.<\/p>\n<figure class=\"wp-block-image\"><img alt=\"What Happens When You Set iPhone to Low Power Mode\" class=\"wp-image\" decoding=\"async\" height=\"576\" loading=\"lazy\" src=\"https:\/\/cdn.howtogeek.blog\/wp-content\/uploads\/2024\/07\/iPhone-LPM-1024x576-1.webp\" title=\"What Happens When You Set iPhone to Low Power Mode\" width=\"1024\"\/><\/figure>\n<h2><span id=\"What-Low-Power-Mode-Does-on-Your-iPhone\">What Low Power Mode Does on Your iPhone<\/span><\/h2>\n<p>You can turn on Low Power Mode from <strong>Settings<\/strong> &gt; <strong>Battery<\/strong> &gt; <strong>Low Power Mode<\/strong> or from Control Center. You\u2019ll see a yellow battery icon when Low Power Mode is turned on.<\/p>\n<figure class=\"wp-block-image\"><img alt=\"Low Power Mode in iPhone Battery Settings\" class=\"wp-image\" decoding=\"async\" height=\"1024\" loading=\"lazy\" src=\"https:\/\/cdn.howtogeek.blog\/wp-content\/uploads\/2024\/07\/Low-Power-Mode-1-475x1024-1.webp\" title=\"Low Power Mode in iPhone Battery Settings\" width=\"475\"\/><\/figure>\n<figure class=\"wp-block-image\"><img alt=\"Low Power Mode in iPhone Battery Settings\" class=\"wp-image\" decoding=\"async\" height=\"1024\" loading=\"lazy\" src=\"https:\/\/cdn.howtogeek.blog\/wp-content\/uploads\/2024\/07\/Low-Power-Mode-2-475x1024-1.webp\" title=\"Low Power Mode in iPhone Battery Settings\" width=\"475\"\/><\/figure>\n<figure class=\"wp-block-image\"><img alt=\"Low Power Mode in iPhone Battery Settings\" class=\"wp-image\" decoding=\"async\" height=\"1024\" loading=\"lazy\" src=\"https:\/\/cdn.howtogeek.blog\/wp-content\/uploads\/2024\/07\/Low-Power-Mode-3-475x1024-1.webp\" title=\"Low Power Mode in iPhone Battery Settings\" width=\"475\"\/><\/figure>\n<p>Here\u2019s what Low Power Mode does when enabled on iPhone:<\/p>\n<h3>1. Display<\/h3>\n<ul>\n<li><strong>Reduces screen brightness:<\/strong> Lowers your iPhone\u2019s screen brightness and makes the auto-brightness feature more conservative.<\/li>\n<\/ul>\n<ul>\n<li><strong>Reduces screen timeout:<\/strong> Sets the screen timeout (auto-lock) to 30 seconds. Your iPhone screen will turn off automatically after 30 seconds of inactivity.<\/li>\n<\/ul>\n<ul>\n<li><strong>Limits refresh rate to 60Hz: <\/strong>On iPhones with ProMotion displays (iPhone 13 Pro and later), Low Power Mode limits the maximum refresh rate to 60Hz instead of the usual 120Hz. However, the dynamic refresh scaling remains active \u2013 your iPhone will still adjust the refresh rate based on content, but it won\u2019t go above 60Hz.<\/li>\n<\/ul>\n<ul>\n<li><strong>Reduces or disables some visual effects: <\/strong>Low Power Mode can simplify or turn off certain visual effects including animations and transitions. These changes are generally subtle, but you might notice a slight difference in how your iPhone looks and feels.<\/li>\n<\/ul>\n<h3>2. Performance<\/h3>\n<ul>\n<li><strong>CPU management: <\/strong>Low Power Mode reduces the CPU\u2019s clock speed. This means the processor runs at a lower frequency, which consumes less power but also results in slower performance, including slower app opening times and gaming performance.<\/li>\n<\/ul>\n<ul>\n<li><strong>GPU management:<\/strong> Low Power Mode can also limit or underclock the chip\u2019s GPU cores to reduce power consumption. This may affect the performance of graphics-intensive apps and games.<\/li>\n<\/ul>\n<ul>\n<li><strong>Additional tweaks:<\/strong> While unconfirmed and not officially documented, <a href=\"https:\/\/www.notebookcheck.net\/Even-in-low-power-mode-the-iPhone-13-Pro-A15-Bionic-chip-still-embarrasses-the-competition.568879.0.html#:~:text=To%20the%20best,performance%20remains%20excellent.\" rel=\"noreferrer noopener\" target=\"_blank\">NoteBookCheck<\/a> and <a href=\"https:\/\/www.reddit.com\/r\/iphone\/comments\/vlpfcv\/a_full_breakdown_of_what_low_power_mode_actually\/\" rel=\"noreferrer noopener\" target=\"_blank\">this Reddit thread <\/a>suggest Low Power Mode disables the two high-performance cores entirely while underclocking the remaining efficiency cores. NoteBookCheck further mentions that even with Low Power Mode enabled, the iPhone 13 Pro Max\u2019s A15 Bionic chip scores high enough in benchmarks, with its multi-core score matching that of the Qualcomm Snapdragon 888. This means the iPhones generally remain quite capable even when operating in a power-saving mode.<\/li>\n<\/ul>\n<h3>3. Background Activity<\/h3>\n<ul>\n<li><strong>Background app refresh:<\/strong> Limits most background sync and app activity, including background data usage, to save battery. Social media and third-party messaging app notifications may be delayed.<\/li>\n<\/ul>\n<ul>\n<li><strong>Pauses iCloud Photos and limits other background activity:<\/strong> Temporarily pauses iCloud Photos sync, automatic app downloads and updates from App Store, and reduces the frequency of fetching new data for Mail and other apps.<\/li>\n<\/ul>\n<ul>\n<li><strong>Turns off auto-play in Safari:<\/strong> Low Power Mode disables the auto-play feature for videos in Safari, preventing them from starting automatically and saving battery life.<\/li>\n<\/ul>\n<ul>\n<li><strong>AirDrop and Continuity features<\/strong>: Apple states that Low Power Mode disables AirDrop and Continuity features on iPhone. And while they may still work with Low Power Mode, it\u2019s best to disable power saving if you want to use these features.<\/li>\n<\/ul>\n<ul>\n<li><strong>Limits 5G connectivity:<\/strong> Low Power Mode on iPhone 12 and later models disables 5G, except when streaming videos or downloading large files, as these activities require faster internet speeds. In some cases, it may also disable the 5G standalone mode.<\/li>\n<\/ul>\n<h3>4. Other Tweaks<\/h3>\n<ul>\n<li><strong>Indirectly improves charging speed: <\/strong>Low Power Mode can indirectly help charge your iPhone slightly faster by reducing active power consumption from background activities. In the <a href=\"https:\/\/www.reddit.com\/r\/iphone\/comments\/vlpfcv\/a_full_breakdown_of_what_low_power_mode_actually\/\" rel=\"noreferrer noopener\" target=\"_blank\">same Reddit thread<\/a>, user u\/gatormaniac shares their experience with charging in Low Power Mode versus without it. They found that Low Power Mode charged their phone 1-2% faster in the first hour. <\/li>\n<li><strong>Helps retain battery health: <\/strong>Low Power Mode indirectly contributes to better battery health by reducing stress on the battery through less power consumption and fewer charge cycles. This can help prolong its lifespan, provided you follow other practices like <a href=\"https:\/\/www.androidauthority.com\/maximize-battery-life-882395\/\" rel=\"noreferrer noopener\" target=\"_blank\">proper charging habits<\/a> and avoiding extreme temperatures.<\/li>\n<\/ul>\n<p>Folks at <a href=\"https:\/\/www.youtube.com\/watch?v=AqhAj-vI10M\" rel=\"noreferrer noopener\" target=\"_blank\">PhoneBuff ran a battery drain test<\/a> on an iPhone in Low Power Mode (LPM) versus not in LPM. Based on mixed usage, they found the iPhone in LPM had about 13% battery remaining while the one not in LPM had 1%. That extra 12% at the end is a significant difference.<\/p>\n<h2><span id=\"Is-Low-Power-Mode-Bad-for-Your-iPhone\">Is Low Power Mode Bad for Your iPhone<\/span><\/h2>\n<p>No, Low Power Mode is not bad for your iPhone. It\u2019s completely safe and designed to conserve battery life by limiting performance, visual effects, background activity, and other connectivity features. <\/p>\n<p>While it doesn\u2019t significantly sacrifice overall performance, you may experience slower app opening times, a slight impact on graphics-intensive games, limited features (such as 5G, background app refresh, and automatic downloads being disabled), choppier animations, and reduced screen legibility under direct sunlight.<\/p>\n<h2><span id=\"Is-It-Safe-to-Charge-Your-iPhone-in-Low-Power-Mode\">Is It Safe to Charge Your iPhone in Low Power Mode<\/span><\/h2>\n<p>Yes, it is safe to charge your iPhone in Low Power Mode. It reduces active power consumption from background activities and other features, which may slightly increase charging speed and reduce heat generation. Low Power Mode will automatically turn off once your iPhone reaches 80%.<\/p>\n<h2><span id=\"CanShould-You-Keep-iPhone-in-Low-Power-Mode-All-the-Time\">Can\/Should You Keep iPhone in Low Power Mode All the Time<\/span><\/h2>\n<p>Technically, yes. But it\u2019s not advisable because it significantly affects performance. Use it when you need to conserve battery, not as a default setting. However, if you\u2019re traveling or without power and want to extend your battery as long as possible, you can use a shortcut to keep your iPhone in Low Power Mode all the time.<\/p>\n<p>Here\u2019s how you can create a Low Power Mode shortcut:<\/p>\n<p><strong>1. <\/strong>Open the Shortcuts app on your iPhone.<\/p>\n<p><strong>2. <\/strong>Tap the <strong>Automation<\/strong> tab at the bottom.<\/p>\n<p><strong>3. <\/strong>Tap the <strong>plus (+) <\/strong>icon.
