Initially, smartphones appearing on the market had replaceable batteries, but over time the standard changed, especially when it comes to flagship units. From the manufacturers' perspective, the use of non-replaceable batteries in phones meant that in the event of repairs it was necessary to use services. It is possible that in the future, however, manufacturers will be forced to use replaceable batteries in their phones. The European Union may enforce such an obligation on them.
So far, only a draft law has appeared, which would confirm changes in electronic equipment. If the change is approved, then manufacturers will have 3.5 years to adapt their smartphones to a form that guarantees battery interchangeability. On each battery, it will then be necessary to include a QR code that will provide information on their capacity and chemical composition. The changes are to be dictated mainly by ecological considerations, which is why the European Union is also to provide users with the opportunity to give back the batteries used so far for free. It is worth mentioning that recently the European Union introduced other regulations for smartphones in the form of mandatory use of the USB-C input for charging phones.
