I used this app for a while on all my phones including a tablet. It's quite interesting to know that my Asus tablet's battery is still healthy at 99% after 1.5 years while other devices don't have such good battery.
Hmm, looks interesting. Just seems to be an app that reports what the battery is doing etc unlike a battery saver app yes?
Maybe your particular Asus' battery was above the nominal specification to start with? My previous laptop had a battery that was 8-10% above the nominal capacity when new, which obviously gave it some headroom for wear. Usage also makes a difference, and the pattern might be different for a tablet rather than a phone.
I judge battery status by performance anyway. According to my apps this laptop has 83% of its nominal capacity, but its battery life is certainly more than 17% less than it used to be (though it's not doing so badly considering that it's 5 years old).
And yeah, I've played with that app. It gives a nice overview of usage, and its foreground usage results seem plausible to me. Its weakness is that it tells you nothing much about background app usage, though that's not a significant drain on my phone anyway.
I've no evidence that my phone had a higher capacity than claimed
It's based on their model of battery wear, where going too high or too low counts as more wear.Still pulling my hair to understand the math used here.
I can't be bothered with that stuff. Avoiding running it too low is one thing, but sitting watching the charge level to pull it when it reaches 80, and then have to be topping up during the day, forget it - I'm not going to run my life around a modest effect on battery longevity. My last phone lasted 5 years without any of that, and that's probably longer than I'll use this one (as I expect 5G networks to be available within that timescale).
And an alarm going off an hour after I go to bed would change my relationship status pretty quickly...
Tesla also recommends not to charge the battery over 90% to avoid battery degradation unless you have a real long trip ahead.
When you're trying to charge 6000+ 18650 LiIon cells simultaneously in a series and parallel arrangement, might be that some overcharging and balancing of individual cells is a problem?

When I charge 18650s for my vape, I always charge them 100%, same with my phones.
Refueling time is critical for most of people. It takes less than 5 minutes to fill the 50L tank in my car. Charging the car's battery would last hours.
