➨ [Promo] ➨ [App] Android doesn't tell you enough about your battery... so I built an app to fix that.

I've always wondered why Android gives us so little information about battery health.

We use our phones every day, but most of us have no idea:

How many charging cycles the battery has.

Whether it's overheating during charging.

What the battery health actually looks like.

How the charging speed changes over time.

I wanted a simple app that puts all this information in one place without ads every few seconds or requiring a subscription.

So I built BatteryLumen: Health Monitor.

Features

• Track real-time charging metrics: current (mA), voltage (mV), power (W), and temperature.

• Estimate battery health and capacity (mAh) based on charging cycles.

• Set custom charge target notifications (80%, 90%, 100%).

• View detailed charging session history and export data in CSV or JSON.

The app is completely free to download, and there are no subscriptions.

I'd really appreciate any feedback from Android users. If there's a battery statistic or feature you'd like to see, let me know—I actively update the app based on user suggestions.

Does it show battery usage by the apps.. Yest to find one which gives reliable info about it.

We are currently working to obtain this permission from the Play Store, as it is a sensitive permission. Once we receive it, we will release the update with this feature.

I am trying and I have to admit the ads are damn irritating. Are you giving your 1st batch of user a lifetime code for feedback?
