Stories of the Samsung Galaxy Note 7 blowing up were rife in 2016, and it seems that the issues plaguing the Note 7’s battery may be present in some form in many other Samsung models this decade.
According to British YouTuber Mrwhosetheboss, the issue of battery swelling in Samsung phones has been found in a large number of his phones, all of which are stored the same way and at the same temperature. While older iPhones, Google and Asus phones look perfectly fine, Mrwhosetheboss found a range of Samsung phones with batteries that appear to be in various stages of swelling.
Some were visibly broken and damaged, but more worryingly, others were only found deformed upon closer inspection, including the recently released Samsung phones Galaxy Z Fold 2 and Galaxy S20 FE, both of which are only about two years old History.
This is serious business because charging a damaged or swollen battery can be very dangerous, with the risk of fire and hazardous chemical leaks. If your Samsung device is about two generations old, then be aware of the “pop-up” look, i.e. the back of the phone is no longer aligned with the rest.
Battery swelling is usually caused by electrolyte degradation in Li-ion batteries, over time the battery’s charge capacity will decrease and you will see the electrolyte break down inside the battery and produce gas as a by-product, causing the battery to swell . Swelling can cause the battery to strain on the device case and puncture it, causing secondary damage to things like your phone or laptop.
Charging the battery at this stage can be dangerous because the electrolyte does not efficiently facilitate electron transfer between the positive and negative electrodes of the battery, which can lead to rapid heat build-up and a potential risk of fire or even explosion.
Lithium-ion battery swelling is not unheard of among most phone brands these days, but Arun and his friends in the tech industry have noticed that Samsung phones are by far the most likely to fail, so much so that he now feels obligated to replace them with Dispose of the sleeves in a fire-resistant manner. If you’re talking about the Samsung Galaxy S10, you don’t have to panic, as Arun and fellow YouTuber JerryRigEverything point out that Samsung has a lot of protections in place to prevent a swollen battery from bursting. Still, we don’t recommend trying to charge batteries that are already noticeably swollen, even those that may be slightly swollen effectively borrowing time.
Samsung told us it’s investigating the reported battery swelling issue and should be able to comment in more detail shortly. Arun did point out that his Samsung device had been collected by the company for further research, while Samsung has not further stated how this was done.
In our own experience, our Samsung devices have not experienced any battery swelling. It may depend on how we use them, and experts recommend storing old and infrequently used devices at around 50% capacity, rather than a full or full charge.
Since the upcoming Samsung Galaxy S23 will look very similar to its predecessor, this could cause concern for the South Korean giant and those who tend to hang on to their phones for a while. But given that we haven’t heard of a Galaxy S20, Galaxy S21, or Galaxy S22 battery bulging, maybe future Samsung phones will see it at a glance.
Likewise, if you’re storing older Samsung phones, we recommend checking them out to make sure their batteries are intact and to determine if they need charging to be safe.
