Optimizing Battery and Data Consumption in Android
Battery and network data consumption are two core issues developers have to deal with when developing mobile apps. This is more of a concern in mobile technologies because smartphones have limited resources. There are two key points I will be focusing on this article: battery life and network data reduction. I will go through some tips and examples on how to save battery life and keep network consumption at its minimum. Optimizing battery life The hardware components that consume most of the battery are the CPU, sensors, and the screen. Sensors include GPS, NFC, Bluetooth, etc. Keeping this in mind is simple to determine what are some points for a developer to focus on while developing. Tasks like keeping the CPU utilization to a minimum required, minimizing the radio utilization and minimizing network operations are difficult to apply in many cases but are necessary to build a top of the line app. In the following sections, I will go through a few factors that have an impact on battery drain. Also, I will mention some tips on how to avoid or reduce battery drain. Carefully use Animations It is obvious that animations need a lot of processing power by the CPU and therefore consume a significant amount of power. According to the documentation, most animations look fluid at 30 frames per second. So, going over 30 frames can be a waste of processing power and furthermore, more battery. Another tip that comes from the documentation is to let the CPU sleep between animations. This is due to the fact that continuous animations lead to constant changes on the device screen. As I mentioned earlier the screen is one of the main factors of battery drain.

Android Nougat 7.0 is the latest official Android Operating System update and is currently available only on 0.3% of Android devices, including the Nexus 5X and 6P, and the Android One devices like General Mobile 4G. As with every update, Nougat brings many new features make users’ experience better, easier and more customizable. Let’s start with the new features of Android N: That square you see in the Navigation buttons now has a new use. If you double-tap it, you will switch between your two most used apps. It is the short form of tapping it once, then choosing the second app window. If you are using Google Docs but you need to check something on Chrome, just open Chrome, find that information and double-tap on the recent apps button that will take you automatically to Google Docs.

6 Medical Apps Revolutionizing Healthcare
Smartphone apps put a world of valuable information at our fingertips, including information about our health. We’re not talking about the ability to Google diagnoses on your phone — the healthcare apps of today are incredibly advanced and are revolutionizing the way we engage with the medical world. Whether you’re a doctor, patient, or researcher, smartphone apps can no doubt provide fast, efficient, and convenient solutions for your medical needs. Apple officially entered the healthcare market in 2015 with the introduction of ResearchKit and CareKit. Those two software frameworks allow doctors and other medical professionals to create iOS apps that can be used to collect medical research data and help people better understand their medical conditions. ResearchKit allows the 700 million iPhone users worldwide to participate in medical studies — and the information gleaned from those studies is used by medical professionals to identify patterns and better treat patients. As well as allowing medical institutions to create apps that work for their research needs, ResearchKit launched five apps of its own, including mPower, an app that’s been used to conduct a large scale (10,000+ participants) study of Parkinson’s disease. That study has already provided researchers with greater insight into the condition.
