Comments on Ampere for Android

★★★★★ Works great, simple, and helps diagnose your cables & power bricks.
★★★★★ Excellent battery charger & notifier app, bonus is the ability to monitor the charge/discharge current. Very reasonable price for a lifetime license.
★★★★★ Actualy I lost original charger, then realized how to confirm the non-original (charger) charging at good speed like original ? . Then I used to test different chargers (installing ampere metere app in phone) in mkt/shops. After many charging testing I purchased the best non-original charger. 👍
★★★★★ It's a super simple app that tells you how much battery you're charging or using which can be very useful for diagnosing charging issues.
★★☆☆☆ Showing only minus while charging on Xiaomi redmi note13 5g. I am not sure if the value is correct though disregarding the minus.
★★☆☆☆ Sigh, Ampere didn't do anything that Accurately can do. The ONE AB never did was cause Android system apps to stop responding or close. Ampere was thus deleted. It only cost me. 49¢ after a Google discount, so there is no loss.
★★☆☆☆ Stopped working since latest update only shows 0 value
