Requirements: Android 2.1+
Overview: Battery Indicator Pro shows your battery charge level (percent) as an icon in your status bar, with temperature, health, voltage, and time since plugged / unplugged in the notification area. Now has an alarm feature.
• Fully configurable green, amber, red, and black icons
• Estimated charge / discharge time left
• Battery logging. You can log the battery state (charge, status, voltage, temperature) and browse the logs on the phone or export to CSV.
• Manually or automatically disable / reenable device lock screen / lockscreen / keyguard
• Alarms (full, charge above X, charge below X, temperature above X, or health failure)
• Themes for main window
• Lots of configurability; most features are optional
• Very lightweight (please email me if you think otherwise, and I'll help you figure out what's wrong — I promise this app will not drain your battery.)
• Open source
• Motorola Droids and Samsung Moment only show every 10%
• It's not possible to replace the built-in battery icon
* Please see the project website (linked to below) to contact me if you have any questions or problems — I can't respond to comments left here. *
What's in this version:
• Updated Slovak translation.
• Improved appearance on Droid X (and possiblity other, similar devices).
• Long-awaited experimental single-percent increments for some (many? most?) devices that previously only showed ten-percent increments. Please see the wiki on the project page for more info, and to report your results.
