I crossreferenced my testing a lot though I cant 100% guarantee what I found is accurate.

Though I can say this: I don’t think built-in health monitors in phones are worth a damn. My gran’s phone was showing at 100% health when accubattery was at a whopping 73%. Testing the old and new battery, the new battery held up just about 30% more time than the old one on youtube playback.

I did other things that I wont get into

This is why I chose to trust accubattery and pretty much invalidate other testing in my head. I know it’s one single test and sample but this is my information and I trust it at lleast for now.
