Hi, there! You have reached the blog of TestDevLab - your partner in software quality assurance. Here you can get to know us better and join discussions about software testing, test automation and development. Please get in touch if you have any questions. Categories Education Hardware Our journey Tags Arduino battery books learning mobile testing our experience Power Monitor test automation Navigation How we test mobile app battery usage Ervīns Patmalnieks (engineer) October 5, 2016 Recently we wrote about a hardware solution that we created to keep our test devices’ batteries from swelling. This time we want to talk about the way and the tools we use to test battery usage of mobile apps. Nowadays everyone wants to extend their phone’s battery life. In fact, battery life is more important to consumers than brand, processor speed or camera quality, according to IDC. For example, the legendary Nokia 3310 phone only had a battery capacity of 900 mAh (nickel–metal hydride battery type). In comparison, the Apple iPhone 7 has a 1960 mAh lithium-ion battery and the Samsung Galaxy S7 Edge has an even bigger 3600 mAh battery. But even with such big batteries, phones can only last for a maximum of a couple of days. And more often than not, our phones need to be charged every day or even a few times a day. There’s an interesting race going on right now. From one side, mobile chipsets are becoming more energy efficient. But on the other hand, apps are becoming more demanding in terms of processing power and we see a growing trend not only in the amount of data used by mobile devices, but in the speed of connections as well. As bigger batteries pose bigger threats of explosion, software developers should be working really hard to conserve as much power as possible in their apps. And we can help with that!

As tools and techniques evolve, testers should stay on top of things by continuously educating themselves. But unfortunately not everyone has the time or the budget to take a course or go to a conference. Well, these days it’s not that big of a problem since you can find a lot of useful information on the Internet, watch a video or two or do some form of online training. You can’t complain about the lack of supply. When asked about great books on software testing, our test engineers came up with this list. Some of these books are older, some newer, but they all are very well written and informative.

Usually when automated software tests are executed on mobile devices, these devices are constantly connected to different devices (computers, power sources etc.) via USB port. USB connectivity not only allows device control during the tests, but also charges the device. Continuous testing affects mobile device battery life and can even harm the battery, which is common for Android smartphones. It seems that iPhones use a “smarter” battery controller. In the header of this post is an example of a Li-Ion battery of a smartphone that has been constantly charged during extensive use. The battery not only damages the mobile device when it’s bloated but also can harm the user and even catch fire. So the problem is real! Read More 0 Welcome to our new blog! Kristaps Skutelis (PR) August 19, 2016 We’re delighted to announce the launch of our new blog. We hope you like its fresh and clean look, it’ll help you find the information you need faster and more easily. We started our entrepreneurial journey back in 2011, and by now have accumulated a ton of theoretical and practical experience in software testing and development. We want to use this blog to share that knowledge and experience. Here you can expect not only observations and opinions about trends in software testing, but also practical tips and tricks about various tools and techniques that our engineers use on a daily basis. Not to mention telling you about our engineers’ side projects. Some of them are really interesting! We’re in for the ride to be your partner in software quality assurance.
