Lithium battery Indicator Pro: https://play.google.com/store/apps/details?id=com.batteries
Lithium ion battery Indicator monitors, indicates the charge level of your lithium batteries in the status bar / notification bar as an charge percentage icon, with temperature, health, voltage, and time since plugged / unplugged in the notification area. You can create a Small (1×1) and large (4×1) widgets.
• Automatic time-remaining estimates based on recent usage
• Several icon sets (including fully configurable green, amber, red, and black icons)
• Small (1×1) and large (4×1) batteries widgets
• Notification (with status bar icon) is now optional — can be used as just a desktop widget
• Status 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)
• Control the notification priority on Android 4.1+ (For example, you can set to “minimum” to hide the icon but keep the notification in the tray.)
• Lots of configurability of behavior and appearance(Pro only)
• The charging indicator (the bolt under the number that indicates when the device is connected to battery charger)
• Very lightweight (App will not drain your power!)
• Shows 1% increments even on most Motorola devices (option needs to be enabled on devices that default to 10% increments)
✔ Note: Almost all other Android devices, report their charge at 1% intervals. However, due to Motorola phone’s design, almost all Motorola devices only show the charge level as a multiple of 10% by default. It means app will not work perfectly on Motorola devices. So Motorola devices should take care about this and uses Lithium ion battery Indicator at your own risk. Current feasible solution is turn on “10% Mode” in Setting -> Status Bar Icon -> 10% Mode.
