Samsung S21 Battery Expanded in Size

[Osamxh]

Im not sure on what to do, I recently noticed my phones battery has expanded in size, Ive had the phone a little over 2 years and actually started noticing that my battery was draining quite quickly 1 year into owning this phone, now the battery dies extremely fast and sometimes shuts off when its at 5%. The back of the phone is kind of sticking out and I believe it is because of the battery as I also see a small bulge in the back. What should I do? I dont feel like Ive owned this phone long enough for it to deteriorate in such a manner.

I would recommend getting a new battery from samsung or a repair centre that gives brand new official batteries or find a battery yourself and install it yourself,
Also when you get a new battery try protect battery, not battery saver, it will limit your battery to 85% but it will increase the lifespan of the battery

First of all stop using your phone, it can be dangerous if the battery becomes punctured. Next thing you should do is take it to a Samsung authorised repair centre to get your battery replaced ASAP. I don't think you can post it due to potential danger. I suspect eventually that your back panel may begin to unstick if the battery expands more, I have had this happen to me and didn't keep my phone in my home. Hope this helps

Back up your files, samsung offers cloud saving for 30 days or do it om your pc. Then discharge the phone (to minimise fire risk) and don't use it till fixing it somewhere authorised
