The best app out there that I've tested for battery monitoring. Except for the notification UI - hard to figure out. Learn from my frustration: Even though they make the same sound which can't be configured, notification sounds and event alarms are not related. Otherwise you'll be putting up with noise for EVERY SINGLE % CHANGE of the battery during charging and discharging if you also want to be notified of boundary conditions like overheating.

I love all that this app does in its monitoring. Battery temperature, signal strength, other things such as the display using the battery, etc. It's cool to be able to open the app and see how all these affect the battery drain. One thing I've noticed recently is that there's an option to show a notification, but there is no notification showing at the bottom of my notifications like I'm used to.

Notification Icon is difficult to read (none of the configuration options provide for a simple large number). Notification and widget do not include temperaterure, voltage, or electrical currents. Measurements are inaccurate and/or take a long time to refresh. There are many many horrible battery apps. This one is not a bad app, just not one of the best. OK for 15MB of memory though.
