Battery Guru: Battery Health v2.5.0.1 build 708 [Expanded] [Mod Extra]
Requirements: 7.0+
Overview: Battery Guru displays battery usage information, measures battery capacity (mAh), show estimates, and helps you change your charging habits with useful tips to prolong battery life and increase its lifespan.

Android shows you the basics. Battery Guru goes deeper.

Get your actual battery capacity in mAh, track health degradation over time, measure real charging current, monitor temperature and see everything on an always-on display or homescreen widget. Battery Guru builds on top of Android to give you the full picture.

Battery Health and Capacity
Your phone shows a percentage. Battery Guru shows you whether your 4000 mAh battery still holds 4000 mAh or has quietly lost 20% of its capacity over time.
– Actual battery capacity in mAh compared to original design capacity
– Battery health percentage and capacity loss tracked over time
– Battery wear analyzed per charging cycle
– Charging cycle count from system data or calculated from your session history
– Maximum temperature recorded during each charging session

Charging Speed and Current
Not all chargers deliver what they promise. Battery Guru measures the real current flowing into your battery so you can compare chargers and cables by actual performance.
– Live charging current in mA and power in Watts
– Voltage readings in mV
– Estimated time to full charge with screen on and screen off shown separately
– Complete charging history with start time, end time and capacity per session
– Compare chargers and cables by their real measured output

Battery Drain and Usage
When your battery drains faster than expected, Battery Guru shows you exactly where the charge is going.
– Screen on time, screen off time, awake time and deep sleep time
– Battery usage by app running in the foreground
– Wakelock monitor to identify apps and system processes keeping your device awake in the background
– Alerts when abnormal battery drain is detected
– Discharge rate and usage pattern history over time

Temperature Monitoring
Heat is the leading cause of permanent battery damage. Battery Guru tracks temperature continuously and alerts you before harm is done.
– Real-time battery temperature with 24-hour history graph
– Custom high and low temperature alarm thresholds
– Minimum, maximum and average temperature per session

Alarms and Notifications
– Full charge alarm so you unplug at the right time and avoid overcharging
– Low battery alarm before you run out
– High battery drain warning when something unexpected is consuming power
– Temperature alarm for both overheating and cold conditions
– Status bar notification with customizable icon showing percentage, temperature or both
– Do Not Disturb schedule so alarms respect your sleep hours

Always-On Display
See live battery stats on your lock screen without touching your phone. Battery Guru includes a fully featured always-on display built for AMOLED and OLED screens.
– Battery level, charging current, temperature and voltage on your lock screen
– Clock, notification icons and media playback controls
– Fully customizable layout and content
– OLED burn-in protection with automatic pixel shifting
– Auto-dim after a configurable time to preserve your screen

Widgets and Overlays
– Homescreen widget showing battery level and temperature at a glance
– Widget with clock for combined battery status and time
– Draggable floating overlay with live battery stats over any app
– Overlay displays current, temperature, voltage and more in a compact view

Bluetooth Device Battery
– View the battery level of your connected Bluetooth devices inside the app

Pro Features
– Ad-free experience
– Full session history for long-term battery health analysis
– Advanced overlays and complete health history
– Free premium: watch one short rewarded ad for 24 or 48 hours of premium access, available unlimited times

Battery Guru reads data directly from your device battery system. It measures and displays accurate values only. It does not claim to modify your battery, speed up charging or extend battery life in any way.

What’s New:
v2.5.0.1
Battery Mentor (new)
– Compare your device against the same model from the community, or against up to 4 devices side by side.
– Phone finder, answer a few quick questions and get matched to a device that fits how you use your phone.
– Rankings, see the top devices in each category.
– Brands, browse every brand Battery Guru tracks, with their devices ranked by battery info.
– Your dashboard now shows how your device performs versus the same model from the community.

Battery health and accuracy
– Health no longer gets stuck on “Learning”, with steadier and more accurate readings, including dual-battery phones.
– More accurate estimated capacity and charging power.
– Fixed wildly wrong usage numbers (huge mAh / mA) on some phones.
– Updated unit conversion (a phone may need one fresh charging session to settle).
– On HyperOS and aggressive-doze phones, per-session mAh is topped up from the kernel charge counter when the sensor was suspended during screen-off charging.

Screen-on and deep-sleep drain
– Better screen-on versus deep-sleep split.
– New rebalance when screen-off drain looked implausibly high (from display-state lag), moving the capacity back to screen-on.
– Multi-signal screen detection (DisplayManager plus PowerManager) shrinks the lag window.
– Fixed Deep sleep / Awake times on the timeline, and the missing “held awake” time.
– Lower overnight drain, the app now idles while the screen is off.

Graphs and charts
– Battery graph, switch between line and bars, and tap any point to see that moment’s details.
– Top apps in the graph now show real icons and names instead of package names.
– Battery temperature chart, per-zone coloring with theme color when normal and red at 35°C and above, the line splitting at the boundary.
– Electric current detail, Voltage and Power now have their own Average / Minimum / Maximum rows.
– Smoother progress animations, and more charging-speed levels (super fast, ultra fast).

Notifications and widget
– “Fully charged” notification fires reliably again, with sound and Tasker support.
– Temperature alarm rebuilt, it updates live with the current temperature, auto-clears when it drops back to normal, and repeats every 15 minutes while still hot.
– No extra alarm sound when you plug or unplug right after crossing a threshold, with a 3 second quiet window after every plug change.
– Widget no longer freezes on stale values during long screen-off stretches.
– Persistent notification keeps its “stick to top” behaviour on Samsung One UI.
– Updated main and unplug notifications.

Overlays
– OLED burn-in protection toggle, a subtle pixel-shift animation like the Always-On Display.
– Customisable overlay color and position sliders.

Premium
– Premium stays active reliably, no more losing it at launch or being nagged to upgrade.

Age compliance
– New blocker screen for users below the age threshold the device reports through Google’s Age Signals API.

Stability and performance
– Fixed a startup crash on some phones, and a crash when browsing devices by brand.
– AdMob callbacks hardened against crashes.
– Lighter sysfs sampling, so the app itself uses less battery.
– “Hide on lock screen” now works on Android 13.
– Many minor fixes and improvements.
