I don't update letest version on this app because I use 2.1.0 version and this version design is my favorite, but I don't like new current version design.

Electron is a very useful and reliable battery information app. It provides details about battery health, charge level, temperature, and voltage in a simple and easy to understand interface. The app runs smoothly and loads quickly, making it perfect for daily use. I really like how organized and clean everything looks. Adding daily usage graphs and detailed health percentage and also app draining calculation would make it even better. Overall 4 out of 5. Recommended!

Worthless. Ads are not justifiable for a gui frontend for utilities baked into the operating system. You put zero effort into this - and honestly if you did that's even more pathetic. Ads are also not justifiable (as in. a premium subscription existing does not excuse this idiocy) on a tool that's used in emergencies to verify charge status

Been waiting for the update for just over a year now. If still supported, the app needs a couple of improvements. 1). Suggest adding a high and low temperature alarm option! 2). The app reads Watts when charging but only detects up-to fast charging; most phones now have Super-Fast charging, it should start recognizing that.

The current update is not work at all on my phone. The app is not giving me any info, even the battery capacity is 0. I really regret updating the app.

Initially a useful and well formatted app. I purchased the lifetime option to remove ads last year, then the developer recently moved to a subscription based model. Now, restoring my purchase does nothing and there are an absolutely absurd amount of ads littering every page and popping up constantly. Pretty scummy move not to honor the original purchases.

Used to be a great app. Now it's just full of ads and completely unusable. Avoid. There are better options that don't open up spam when you're just trying to use the app as intended. Again, it's been made unusable. The developer has lost their mind if they think the subscription prices are even remotely reasonable. Not that this review will change a thing, but perhaps I can help people avoid trash.
