Battery life. We all want it, yet we don’t want to sacrifice our thin, light, and always connected phones for it. So what’s the answer? Well you can slap on a big fat extended battery. But why go through all that trouble when you can just install an app for $0.99 and be done with it? Well that’s what Power Manager Full might lead you to believe. However, what looks too good to be true usually is.
Power Manager Full is a profile manager that lets you toggle different options for different circumstances. For example you can set your screen brightness and screen time out to different levels for when your phone is plugged in or at different battery levels. You can also turn on or off wifi, bluetooth, or gps. The app also claims to add a â€œnew setting,â€ allowing you to set a screen time-out when you are on a call.
The real question here is: does this actually translate into increased battery life? Well, it depends. Yes, setting your screen at a lower brightness will prolong battery life. Also, turning off bluetooth and wifi will also increase battery life. But you might be asking: I keep my brightness on auto and my bluetooth and wifi off anyway, will this app help me? Probably not. Also, claiming that a in-call time-out is a new setting is a bit of a stretch. There is a proximity sensor for that very reason.
I also found that the default settings on this app were too aggressive. My screen kept dimming when I was reading in my RSS reader. Not only that, but editing the profiles is a bit confusing. When you tap on a profile there is a pop-up that says what profile you just tapped on – but nothing actually happens. You have to long press the profile to edit it.
Power Manager full does give you some added automation if you want different things to happen when you plug your phone in. However, there are apps that use your location as a trigger that I find much more useful. For example: turning your wifi on while at home. As far as battery savings, this app will do nothing for you if already do the most prudent things such as keeping your screen brightness down and you wifi and bluetooth off.
I’ve got an idea. Instead of paying $0.99 for an app like this we can put that money towards funding scientific research for new battery tech. Because it seems like this problem just isn’t going away on its own. And while I applaud developers attempting to assuage the problem, I think more honestly marketing ones product is a better approach.
