Maxing Android Battery Life
This Motorola Droid 4 has a great keyboard and it runs Android 4.1.2, a version of Jelly Bean. I like this phone. I love this keyboard. And, while Android 4.1.2 isn't Android 4.3, it's none too shabby. So what's wrong with this picture?
Notice something about the screen? It's off. And, why is it off? It's off because the battery has run out of juice AGAIN!
Of course, all battery powered devices do this and, as 4G LTE phones go, my Droid 4, with its 8 hours of active use time, isn't bad at all.
But, I want more. I want the maximum possible battery life for my smartphone and my 2012 Nexus 7 and 2013 Nexus 7. Of course, the first thing I did was to use all the various tricks to maximize my Android devices' battery life.
That helped, but I wanted more. If you're like me and only the best battery life will do you need to check out these applications. They'll help you to make the most of your Android smartphone and tablet's batteries.
What the heck is a Wakelock? It's the feature Android lets apps use to wake it from deep sleep mode. Wakelocks can keep your CPU awake, they can turn on your screen, and they can make sure your screen doesn't go off. That can be very handy. They can also help kill your battery.
UzumApps' Wakelock Detector is a handy program for seeing which programs have been using wakelocks. It gives you detailed system information that's essential for hard-core battery life analysis. It's not for casual users.
I like this program a lot but to really use it effectively you need to be an Android power user or developer. If that's you, you'll like this free program a lot.
KS Mobile's Battery Doctor is a really easy to use and helpful battery analyzer tool that doesn't require a degree in electrical engineering or computer science to be useful. What I particularly like about it is that it gives tips on what apps and components to turn off to get the most from your battery. Its battery charging utility is also very handy.
While I've found its battery life estimates to be a little optimistic, I can forget it that for its helpfulness, simple interface, and price: Free.
