Why removable smartphone batteries disappeared and could make a comeback

Removable smartphone batteries were once a standard feature, allowing users to replace a depleted battery within seconds. Today, however, nearly all modern smartphones come with sealed batteries, reflecting years of design changes driven by performance, durability, and consumer demand.

Manufacturers gradually abandoned removable batteries as smartphones became thinner, lighter, and more sophisticated. Permanently integrated batteries allowed engineers to optimize internal space, making room for larger camera systems, more powerful processors, wireless charging components, and improved cooling technologies. The sealed design also made it easier to produce devices with premium materials such as glass and aluminum.

Another major advantage has been improved durability. Without removable back covers and battery compartments, manufacturers have been able to offer stronger resistance to water and dust, helping smartphones achieve high IP ratings that are now expected by consumers.

Security has also played an important role. Because modern batteries cannot be removed instantly, stolen phones are more difficult to disable, allowing tracking features and remote security functions to remain active even after a device has been lost or stolen.

Despite these advantages, many consumers continue to criticize non-removable batteries because they make repairs more difficult and often more expensive. Replacing a worn battery usually requires specialized tools or professional repair services, encouraging concerns about electronic waste and product longevity.

These concerns have prompted lawmakers to take action. The European Union has adopted new regulations aimed at improving the repairability of portable electronic devices. Under the new rules, manufacturers will be required to design products so that batteries can be replaced more easily by users or independent repair providers. Spare batteries must also remain available for several years after a device is discontinued.

The legislation is expected to take effect in 2027, although some manufacturers may qualify for exemptions if they can demonstrate that their batteries maintain a high level of performance over extended charging cycles. Companies will likely need to provide technical evidence showing that their battery technology meets the required durability standards.

Industry analysts believe the new European rules could influence smartphone design well beyond Europe. Since many manufacturers produce devices for global markets, they may choose to adopt a single design strategy rather than create separate versions for different regions.

While removable batteries are unlikely to return in the same form seen on older mobile phones, future smartphones may become significantly easier to repair and maintain. The growing emphasis on sustainability, longer product lifecycles, and the right to repair is expected to shape the next generation of mobile devices, balancing innovation with greater consumer choice.
