About this app

★ MONITOR YOUR BATTERY HEALTH
BatterySnap is your battery health monitor for Android. Track health, drain, temperature, voltage and power — beautifully. Know your battery inside out.

★ WHY BATTERYSNAP STANDS OUT
- Real sensor readings — voltage, current, temperature straight from your device
- Long-term history: months and years, not just the last 24 hours
- Multi-scale graphs that zoom from minutes to months
- Free with a generous core; upgrade to Xtra if you want extras widgets and no ads
- Built by battery nerds, for battery nerds ;)

★ DEEP BATTERY ANALYSIS
- Multi-scale, interactive real-time graphs (how did you live without them? ;))
- Months of battery history at your fingertips
- Analyze charge and discharge cycles
- Track temperature, voltage, current and power consumption
- Compare your device against others of the same model worldwide
- Spot drain culprits

★ POWERFUL WIDGETS
- Fully customizable home-screen and lock-screen widgets
- Live level, temperature, voltage and charging time
- Multiple widget styles to match your launcher
- Lightweight: minimal battery impact

★ MONITOR FAMILY AND FRIENDS battery levels
- See your loved ones' battery levels in one place
- Set per-device high and low battery alert thresholds — pick the exact levels that trigger a notification for each phone
- Get a heads-up when their phone is about to die
- Perfect for parents, partners, and the chronically forgetful ;)

★ SHARE YOUR GRAPHS
- Export and share battery graphs as images
- Show off your charging discipline (or lack thereof)

★ PRO TIP
Pop a widget on your home screen and let BatterySnap run for at least two days — that's when the magic kicks in. More data means sharper analysis.

★ ANDROID 6+ HEADS-UP
The system aggressively pauses background apps. For continuous, gap-free graphs, exempt BatterySnap from battery optimization in Settings. Two taps, a lifetime of clean data.

★ BatterySnap Xtra!
Upgrade to BatterySnap Xtra! to remove all ads, get smart alerts when battery is high or low, see the level pinned 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?
