3C Battery Manager user reviews :

Great app, only 2 real complaints are the min/max graphic legend on the widget is super tiny and almost impossible to read, and the app no longer has a battery health indicator on the status screen. Even after changing the text size in the app and on my phone the min/max graphic legend doesn’t change size. The absolute value legend tex changes size beautifully when I change the text size setting, but the min/max values stay their impossible to read size.

After owning the paid version for so long, this is worth more than I paid for. The Dev has been relentless in issuing updates. Thank you. I may not understand every thing that I see in this app but the feature that I like the most is the customizable line indicator. This is the one I can’t do without.

I like it, so far, but i would like to see it’s full potentially without having to pay for it though. But for some reason, i think that’s highly unlikely.

On the latest version, the history tab show 0.00%/h regardless voltage (mV) and battery % are dropping.

Works great. Very responsive developer.

I don’t need any of the pro features, but anyway I bought it just because it helped me to prove that the new battery I got from a repair service was faulty! The history showed that wrong temperatures were recorded starting from the time I got the new battery. As a result, I easily got a replacement today from the shop.

No partial clearing of history. latest version no good . i have to revert to the older version every time auto updated. by the way play store ever so often changes my setting of no auto update very annoying

Love this app use it on all my phone

I really like the app but noticed the pro version I purchased is no longer. Looks like you have to start off from scratch and purchase each component which I’m not happy with. Again it is a really good app but I feel since I already purchased the pro version a long time ago, now I have to buy each feature individually. Not happy with that.

I have never been more impressed by an app much less a system tool. I downloaded and skimmed the app a few days ago. Saw potential, but wanted to give it a few days to accumulate data. I just clicked evey button and am floored. I was sold before i saw the change log. But a $5-10 system tool that doesn’t have holes to fill by another app, and will probably maintain (or improve) usefulness indefinitely has more value than my experience can estimate. I have never paid money through the app store or

Great for showing the rate of charge in mA to see if a charger and cable are really fast charging or not. Also good to check the battery temps when charging, as too much heat will cut down on the battery life. Able to take stats every 5 mins and doesn’t drain the battery
