Recently, I’ve been trying to gauge how reliable my Nexus S battery is. Guessing averages and predicting the time until you lose your electronic life line is all well and good when you take into account how rubbish the stock Android battery-usage app is. However, there is no excuse to not waid through XDA-Developers and see if you can find something better, which I’ve been doing.
I browsed across an interesting app called DrainGuard by XDA member walda, which boasted the ability to collect and store battery-usage data while your phone is on standby, and display it to you when you turn on your phone again. It’s helpful, because it means that you’ll never go without knowing how much you’ve wasted, how much you have left and how much you should have saved not watching all of those YouTube videos of cats. (It doesn’t have that feature, but let’s be honest, it would be awesome if it did.)
One of my favourite features of this app is the “Drain On/Off”, as seen in the photo to your right. It allows you to see how much battery you’re draining per hour, with the screen on, in comparison to if the screen was off. I find that statistic weirdly interesting, because it’s cool to see how much power smartphones to eat up, even when they’re off.
DrainApp guard is available as a trial on the Market, allowing you a considerable trial period to test the app and make sure that it works well on your device. If you want to grab it, head on over to the thread, follow the links and QR codes, and leave the developer and nice message of support._________
