Systemic battery bulging across multiple generations and models of Samsung phones
Batteries are not self-igniting like the Note 7 so for the moment, the issue appears to be a slow motion car crash rather than an immediate global recall event
Does not mention whether it is battery quality, fast charging or something else as the root cause
Hmmm, maybe @tallguyinoz 's post is related to this issue and it isn't the cable: https://www.ozbargain.com.au/node/726746
I worked in telco when the Samsung a50 came out, and good god I saw so many swollen batteries in that phone
Weird, I know of maybe 10-20 old Samsung phones in use within my extended family/friends and none of them have this.
Including phones that have been stored / charged up later for use as backups.
I have a Note3 that I occasionally get out and flash random roms for fun and only recently the battery started to bulge. Not bad for a 9 year old phone.
I think the video says battery bulging issue started to occur in phones after infamous Note 7. The older ones may be differently built.
Sample set:
S21 Ultra used frequently
S21 used frequently
S20 used frequently
S10 used frequently
S10 stored for 2 years and then used frequently
S7E used frequently
A20 stored for 3 years unused
S8, S9, S20, S21 stored for 3-4 years unused
plus a bunch older than that (S3/S4 etc)
I had that happen to an old iphone 3gs. I think cos it was left in a drawer and it gets pretty hot during summer in my room.
exynos or snapdragon ?
Very interesting.
Ive had the s6 edge plus, and so many others. I've used and kept them as back up phones (ie, unused in drawer) and Ive never had the swollen battery issue.
Still have my og fold, s10+ and that's fine too.

Have two old Note 8s, both looks ok for now. Hopefully this is isolated in just certain manufacturing regions.
Jerryrigeverything mentioned in the above video it’s likely bad battery quality (bad quality control).
