While interesting, you kinda need to know how long a charge lasts for it to be informative.

For example, it wouldn’t be as impressive if you also had to charge it more often than the competitors.

True, but there's a relatively large number of remote workers where battery life on a daily basis isn't important because there's always a charger nearby.

I would guess that manufacturers can alter the battery charging algorithms and claimed battery life to hit a specific number of cycles and/or battery life. It's a matter of tradeoffs as long as the phone hits 800 cycles, the mandated minimum.

Samsung for my next phone it is. I've had mine for 6 years and battery life is still great.

If battery life is the only/main concern, sure

Other concerns? A dead phone regardless of capabilities is still a dead phone.

A great phone were you need to replace the battery after 2-3 years is better than a mediocre or bad phone whose battery lasts for 20.

Well that takes the iPhone out of the running at least. It's definitely hard to find the right device these days.

I can’t remember the last time I had a dead phone.

The source for these figures is self-reporting by the brand, so take it with a grain of salt. E.g. JENBIZZ MB1001 tablet lists 8000 charge cycles.

But when the batteries fail, do they catch on fire? That's the problem with Samsung, lol :(.

Isn't it just one model which was a combination of design and manufacturing defect?

It wasn't just one model that was broken--though the one you are thinking of was particularly bad--but of course it is a combination of bad design and a defect... what else could it be?... the batteries somehow revolting?... a coordinated cyberattack?... like, obviously it is bad design and a manufacturing defect ;P.

Here is a video that went into a lot of analysis on the wider-scale issues of Samsung's low-quality batteries.

The reason I switched to Samsung is because I had an Apple device and then a Google device reach the end of their usefulness at the two year mark. The 3 Samsung phones I've had since then have lasted to the 4 year mark and I was able to replace them on my timeline, not the device's.

The S20+ I'm typing this on is 4.5 years old and feels as functional as the day I got it, it does not feel slow at all and if the battery life has lessened I haven't noticed.

My mum is using my old 12 Pro, which is about the same age as yours. She’s still happy with it, though to me it feels old.
