One of these ‘vampire settings’ which drains the battery life is ‘WiFi assist’, so if you’re somewhere connected to the internet but it’s being a bit slow for whatever reason this setting will kick in and use some data to bridge the gap<\/a>. <\/p>\n Sounds good and convenient if you need to load the next TikTok or whatever you’re doing, but it’s a bit of a pain on your phone battery and if you keep it on you could end up seeing that percentage fall even further.<\/p>\n As long as you’re fine with the WiFi being a bit naff every now and then hope into the ‘mobile service’ part of your settings and scroll down until you find it, then until the option to disable it.<\/p>\n Bear in mind that this could mean you experience a bit more lag when your Wi-Fi has an interrupted connection. However, it will help to make your phone’s battery last longer.<\/p>\n Not only that, but Wi-Fi Assist can also sneakily use up a large proportion of your precious data when you think you’re safely on a Wi-Fi network. Turning it off can help you to use less of your data plan as when you’re on Wi-Fi it won’t sneakily switch on.<\/p>\n It is there for a reason and it’s not always terrible to have on, but only when you’re sure you need it.<\/p>\n Apple’s<\/a> website says: “For example, if you’re using Safari with a poor Wi-Fi connection and a webpage doesn’t load, Wi-Fi Assist will activate and automatically switch to cellular so that the webpage continues to load.”<\/p>\n It’s definitely useful for some things, nobody likes to be stuck there waiting, staring at an empty screen begging for it to load up.<\/p>\n It’s always a tossup between your convenience pitted against your phone’s battery life and your data usage.<\/p>\n If you want to keep your phone going for longer then you might also want to look into how you’re charging the battery.<\/p>\n Most people stick it in every night and wake up to a phone at 100 percent.<\/p>\n But Chao-Yang Wang, the director of the Electrochemical Engine Centre at Penn State University, claims otherwise<\/a>.<\/p>\n![\""It](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/04\/aHR0cHM6Ly9ldS1pbWFnZXMuY29udGVudHN0YWNrLmNvbS92My9hc3NldHMvYmx0Y2Q3NGFjYzFkMGE5OWYzYS9ibHRiYjY2OGFh.webp\"\/)
