YouTuber says Samsung may have a problem with swelling phone batteries

Samsung may not have left its battery woes completely in the past. YouTuber Mrwhosetheboss (aka Arun Rupesh Maini) and others have noticed that the batteries in Samsung phones swell disproportionately. While this most commonly affects older devices where balloon batteries are more likely, some of them are only a few years old – for example the 2020-era Galaxy Z Fold 2. It’s usually obvious (the back of the phone is peeling off), but it can be so subtle that you might not realize your battery is in a dangerous state.

Battery swelling isn’t a new problem or unique to Samsung. As lithium batteries age, their increasingly faulty chemical reactions can create gas that inflates battery cells and increases the risk of fire. This author has seen two non-Samsung phones meet their end this way. It’s more likely to happen when you don’t charge or discharge a battery for an extended period of time, and many companies (e.g. Apple) recommend that you keep batteries charged to around 50 percent when you won’t be using a device for an extended period of time.

The concern is that Samsung phones in recent years have been more affected by swelling than other brands, and the power adapters are designed to last five years without such dangers. Tech video makers are uniquely good at tracking such issues — Maini and guys like him often store dozens or hundreds of phones in identical conditions, though they don’t necessarily keep the phones on proper charge levels.

It’s not clear how pervasive the problem is or how systemic it might be. We reached out to Samsung for comment and will let you know when we receive a response. However, it’s safe to say that the company would rather not dwell on more battery issues. The Galaxy Note 7’s fire-prone battery prompted Samsung to issue a massive recall that (temporarily) tarnished the company’s reputation. Aside from that, the crisis also led to a focus on battery safety and served as a red flag for the phone industry. Last but not least, the swelling reports could enlighten users and manufacturers.
