Accubattery health!

[Wbutchart1]

Hi I was wondering if anyone else uses accubattery and how accurate it is? I've had my note 9 for 4 months and I was expecting a battery health of at worst 96% yet I'm getting a reading of 90%! 10% deterioration in 4 months seems terrible, and I generally keep charge level between 40-80%.

Check out table 1 in this article. One of the things they noticed was all of the test batteries started between 88-94% of their advertised capacity. So I'm not surprised by your results.

You can safely ignore accubattery and uninstall it. It's not accurate at all, mainly because your phone is already lying about its percentage capacity, and accubattery relies on it.
Even accubattery's own documentation at their website says that phones nowadays report 100% despite not really being 100% capacity. This would cause trouble for the app's estimates.

I used it a number of times over the past few years and after a while, found it was a distraction and I just recharge my phone whenever I need to.

You just made me feel better. My new Note 9 is at 94%. I thought it was horrible but apparently it is better than average?

It seems to be a common theme for Li-ion and Lipo batteries.
