AccuBattery and AnTuTu. Make sure to run Android 10 so you have access to Mah readings. If you're using AnTuTu, charge at least 80%, otherwise the reported values will be ridiculously inaccurate. AccuBattery delivers somewhat reliable values for charges 30% or greater.Which app to use to check battery condition? What point would you choose to think about changing battery. I still manage 1.5 days of use. What battery would you recommended? Link?
