Add a widget to your home screen and let BatterySnap run for a couple of days. More data means sharper analysis.

★ Android battery optimization
Android pauses background apps to save power. For continuous, gap-free graphs, exempt BatterySnap from battery optimization in Settings.

Free at its core. Upgrade to Xtra to remove ads, get smart high and low battery alerts with custom per-device thresholds, pin the level to your notification bar, and unlock extra widget styles.

Admittedly I didn't know what the purpose of the app. was for,but when it showed me a graph of how much your battery was charging and discharging. I though the battery was draining pretty fast. Not due to the app. But was actually showing it was discharging at a smaller rate than I thought. Thanks developers for this app. My paranoia about my battery usage was answered. My phone was charging,and discharging at a normal rate. Again TY developers for this app. Download this app. It was very useful to me.

Great app, i don't use it often but it allows me to see how new apps drain the battery. One flaw that would make it 5 stars not 4, I can't find a way to export the data for further analysis.

Actually there is a way to export your data. Just go to the root screen of BatterySnap, and touch the 3 dots at the top right. There is an "history export" option, click on it. You will receive a notification with the location of the export file when the data is on your device. Then you will be able to put the zip file on Drive for example.

Wow. I find new things everyday that this app can do... 5 Stars... update: I am disappointed that this app seems to drain battery even when not in use... uninstalled for now, lowered to 4 stars.... it still does great things...

It is quite strange that Battery snap started suddenly to use battery. It has been designed to be very conservatibe on this extent. Did you check that in system settings? Are you sure it did not ue battery because you played a lot with Battery Snap?

What’s new

- Add a monitored device to get the paid BatterySnap Xtra add-on for free — keep it or gift it to a friend
- When sharing your device for monitoring, it's now clearer that you can revoke the other device's access at any time
- Monitored-device low/high battery alerts now show when the level was reached
- Set low and high alert thresholds right when you add a monitored device
