My Battery

you can analyze the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions:
- Spot drainers based on detailed information about the root cause
- Use the online Knowledge-Base to find how to reduce or remove the wakelocks
- measure the effect of actions to reduce drain
- detect changes in the awake/sleep profile and quickly find the causes (rogue apps)

Key Features:
• Fully configurable estimated charge/discharge time left.
• Logging of battery state.
• Themes for the main window (including a full-size window with large, easy-to-read text).
• Manually disable/reenable the device lock screen, with the option to automatically disable it when plugged in and reenable it when unplugged.
• Battery logging. You can log the battery state (charge, status, voltage, temperature) and browse the logs on the phone or export to CSV.
• Alarms (full, charge above X, charge below X, temperature above X, or health failure).
• Lots of configurability of behavior and appearance.
• 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!)
• Shows 1% increments even on most Motorola devices (option needs to be enabled on devices that default to 10% increments)
• Well-tested and supported on ANDROID2.1+
• Many more useful things that you'll discover.
