It's a great replacement for the AccuBattery app. I wouldn't mind a few more data points, such as a chart icon for when an OS/Play Store/Sec Update occurs and a floating icon for the Usage Discharge chart the period bar (30min) if that period had screen usage above a certain threshold (helps isolate high-usage). A few more usage bins (colors, e.g. green, yellow, orange, red) could help visually see abnormalities. The next step would be to introduce rolling averages and alerts for high usage.

App is ok but it's really not great. So many good ideas but they aren't fleshed out. Example: my phone turned off from heat. I'm curious what it got up to but the data only goes back to when it booted. And there's lots of other things like that. Some things have really cool graphs (even if the data ranges aren't complete) others have a completely different style that is almost useless because the bars in the chart are too large. There's no granularity to its data presentation. Hope it improves.

My first choice go to battery monitoring app. Provides reliable, accurate, data, access to details of all kinds, great history, all in a great, easy to read, and comprehensive gui. Updated regularly. Ads are just starting to get a bit overly intrusive and misleading, making it seem like they are part of the app though. It's too bad, as I think it's the best battery app in the play store. Change size and graphics off the ads and I'd rate it 10 stars!
