Make your smartphone or tablet battery last longer! Good range to aim for when charging a Li-ion battery is from about 40 to 80 percent in one go. A bunch of tiny charges throughout the day is your second best bet, and going from zero to 100 and then 100 to zero on a regular basis will put the most strain on your lithium-ion battery. Healthy Battery Charging notifies you when to plug or unplug your phone from the charger in order to improve the battery life. The app itself is optimized for low battery consumption, running in the background and checking the battery level every 15 minutes (configurable). The exact timing of these checks depends on the Android OS, which might schedule them alongside other tasks or delay them when in sleep mode. As a result, the battery level may slightly exceed the high threshold while charging or drop slightly below the low threshold while discharging before you receive a notification.

Simple way to estimate the heart rate. Please do not use it for medical purposes ! This utility works by covering the flash as well as the device's camera with a finger, and waiting for 10 seconds. It works best when the person stays still, and the environment is dark. The phone analyzes the amount of red captured by the camera, and attempts to calculate the heart rate based on the subtle changes it detects. During the measurement, the application shows the current calculation results, and shows the captured data on a line chart. Once completed, the following further details are shown: Standardized values, along with their timestamp (the values are scaled between 0 and 1, and a rolling average is applied for smoothing) Timings where a new heart beat is detected. These data can be shared with other application in order to be exported.
