By Chris Smith October 16, 2013 0 44 271 101 Samsung has apparently confirmed that it will offer free battery replacements to Galaxy S4 owners that experience certain battery life issues with their batteries including battery swelling.Advertisement In a to a comment issued to Trusted Reviews, Samsung acknowledged the problem, saying that only a “limited number of customers” are affected: We are aware of this issue, which has affected a limited number of customers. We ask all affected customers to please visit their nearest Samsung Electronics service centre, where they can receive a replacement battery for free of charge. We remain committed to providing the best possible user experience for our customers. However, some reports claim that the actual number of affected Galaxy S4 units is actually larger than one would expect. MobiFlip reported a few days ago that as many as 30% of Galaxy S4 units purchased from a German provider have faulty batteries, saying that it has obtained is information from an insider familiar with the matter. An actual number of affected buyers is not mentioned in the report, and Samsung will probably not mention it either – after all, it’s bad press as it is that a six-month smartphone already experiences battery problems that shouldn’t appear in new devices. For some reason, these faulty batteries are not able to hold a charge anymore, with some of them swelling up – this is a common security practice for batteries in electronic devices, although it’s not everyday you hear about this happening to a mobile device. The image above shows the difference between a regular Galaxy S4 battery and one that has swollen up (on the right). That said, we’re interested whether you have been affected by such Galaxy S4 battery issues yourself, and whether you have received a free replacement from Samsung.
