Iphone 6s battery problems

So I bought an iPhone 6s back in October 2015 and it has been serving me well for more than 3 years. Performance wise it is still excellent even by 2019 standards. The main thing troubling me was battery performance, battery life and lifespan. So I back in 2016 in noticed my phone would start to randomly shut down even though it indicated plenty of charge percentage wise. 20%? 30% 34%? it didn't matter, it would randomly shut down. The reverse was frustratingly also true, 1% charge and... nothing happened, you could happily watch another half hour of video without having it shut down.
Fast forward to december 2016 and Apple had a recall program for my model 6s. Great! (see ifixit for a great overview of all the battery issues). And I started 2017 with a fresh battery and all was great.



Until 2019 and the shutdowns, the unreliability and the frustration started again. The new battery health tool indicated 82%. this was not what I was experiencing phone life was not down from 15h to 12h a day it was a matter of hours. I would open up my phone only to see up to 20% of the battery capacity be blasted off in one moment. I would charge the phone up to 3 times a day. Needless to say I replaced my battery again. So let's see what happens, I should be good till 2021.


Summary
