Experts have explained why removable batteries disappeared from modern smartphones and how new European Union rules could bring the feature back to devices by 2027, reports infohub.kz.
In the past, replacing a battery took just seconds: you simply popped off the back cover. Today, almost all smartphones come in unibody designs. The main reasons for ditching removable batteries include the push for thinner devices, the shift to premium materials like glass and metal, and the need for water resistance under IP67 and IP68 standards. Additionally, built-in batteries encourage users to upgrade more often.
Currently, removable batteries are rare, found in devices like the rugged Samsung Galaxy XCover 7 Pro or the modular Fairphone 6. However, that's about to change. In February 2027, an EU law takes effect requiring manufacturers to make batteries easily replaceable with standard tools. Similar requirements already pushed Apple to adopt USB-C. That said, the law includes exemptions for brands whose batteries retain over 80% capacity after 1,000 charge cycles while offering high water protection.
