Actually, since battling my phone addiction, my battery holds up the whole day. I use an iPhone 14 Pro, right now I’m 6 hours in my work day, currently on a break, typing this with 92% remaining. Half a year ago I’d have charged it by now because it would have had less than 20%.
You should not charge more than 70-80% to preserve the battery
Not on modern-ish devices. The battery controller already does it for you and shows you 100% when it is not physically at 100%. Plus, lithium polymer batteries are not as affected by this issue as older battery types. This is an old myth basically.
The battery in our devices (including the iPhone 14 Pro that the person I replied to has) are Lithium-ion and absolutely severe from this. BMS and other system like the kernel and OS do report for a different value of battery but they do not diverge from the physical level this much. The further from 100% you can stop charging the better, 60% being an even better rule. Polymer batteries does not mean anything in itself, but the common part is they still are Lithium-ion and need to be treated the same way Please stop spreading false information, even more when answering someone, and furthermore when this misinformation is dangerous for the climate you depend on

Fair enough, but the difference is not that much considering that you have to charge your phone more often if you stop halfway. Plus, devices are so power hungry these days, you need that extra % to last the day sometimes. Still, we can all agree that batteries will fail and should be swappable. They can be recycled almost in full. EU is doing good on this one.
Sorry for being defensive You are right we have to charge them more often which can be a burden but it's still best for the battery chemistry. It should not come to 1% charge-discharge though, but cycle between 30-80 is great.
It's true that in the end we need more and more those extra pourcentage so another reason to treat our batteries right from the start so that they keep their full capacity longer.
And completely agree that all constructors should let us repair our phones, including swappable battery from home
I just realized that the only reason I noticed my old phones' battery swelling was that the back cover is removable and got pushed out.
Now I'm terrified of my current aluminium unibody.
I don't think you have to be scared about this, it's rare. Just don't let it deplete itself too often (>20% for daily use and a full discharge/charge once every two weeks to recalibrate) and don't expose it to low and high temperatures
Why would you recalibrate every two weeks? I did it once after 2 years and it made no difference
You don't HAVE to, this won't probably have an impact in the long run. I myself recalibrates maybe once per month. But it is easier to handle your battery level precisely when the measures you get are themselves precise. And it is more conveniant to not be caught offguard with less battery than anticipated. But yeah not mandatory to do it too often, just regularly
