battery saver for android phone

Principle Overview: The acquisition of cell phone battery power is also frequently used in application development. In Android systems, messages that change cell phone battery power are broadcast using Intent, and commonly used Intent actions include Intent. ACTION_BATTERY_C

How to maintain the Android mobile phone batteryWhen a mobile phone is charged, it does not need to consume all the power. When the machine prompts that the power is low or the remaining power is insufficient, it can be charged.Tips for using cell phone battery:1. Do not ove

minimize the power consumption, you can use the intent obtained above to obtain the level and scale of the current power, and then calculate the percentage of the current power. Sample Code: int level = battery.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);int scale = battery.getIntExtra(BatteryManager.EXTRA_SCALE, -1);float batteryPct = level / (float)scale;Monitor significant changes in battery power Generally, we do not need to constantly monitor th

This article describes the implementation of Android programming to monitor battery status. Share to everyone for your reference, specific as follows: Recently in the development of a GPS-related project, because it involves the use of GPs, it is well known that GPS is quite power consumption, so think how to know the current electricity, and when the electricity reaches a lower limit, timely reminder to t

Android Battery status monitoring If you want to monitor changes in the battery status, you need to dynamically register: android. intent. action. BATTERY_CHANGED: After receiving the Action, you can obtain the information you need based on the corresponding Key. For more information, see the BatteryChangedReceiver cla

Battery usage has always been a top concern for smartphone enthusiasts. As more and more applications increase, people need to charge at least twice a day. This also causes the battery problem to be thrown to the Cusp again. To this end, the android team provided a series of "courses" for its developers to teach some smart p
