Hello, Normal battery from 100 to 0 usually lasts 6-7 hours with normal day usage, but if it’s a busy morning it can last as little as 3 hours. With low power mode on my iPhone last sooooo much longer. Like an actual full days worth. And I mean with regular usage such as web browsing and listening to music. Like a full realistic 24 hours and many times 36 hours. I’m wondering if this is bad for the battery life long term since the feature is so great. My only qualm is that low power mode is turned off automatically when my iPhone reaches 80% charge, lol.
