I am familiar with the phrase battery hog.

Is this a common phrase?

Is there any better expression?

    "Drain on the battery" is probably a good as anything. And I've probably heard "battery sucker" once or twice. – Hot Licks Oct 26 '15 at 9:13

    A quick search on google reveals the most common (that i can find anyway) phrase for this is battery drain, and returns over a million relevant results when searched. I more often hear people say that something eats battery although this doesn't seem to be very common on the internet – 123 Oct 26 '15 at 9:14

    I personally like the fairly obscure term vampire app. – Bookeater Oct 26 '15 at 9:15

    @technophyle Personally, I would go with "battery killer." – Elian Oct 26 '15 at 9:20

Battery hog is a good expression. It would be instantly understood in the tech field. By way of analogy, we call CPU-intesive apps CPU hogs, as in Chrome could be a huge CPU hog.

Here's an example from CNet:

GPS is a huge battery hog, as it harnesses data from the phone's GPS chip, cell phone towers, and Wi-Fi hotspots to find your location


Or you can simply say battery drainer:

Surprisingly, the Wal-Mart (WMT) app is the top battery drainer among U.S. Android users in this category.


The adjective battery-intensive could work as well:

What are the most battery intensive apps?


Edit: These may not be very common, but they still, I think, deserve a mention:

battery killer:

No, GPSD is not the battery-killer on your Android!


Can somebody help me figure out what is draining my battery so much? - springtomize is definitely a juice killer...


The big Note 4 big screen will likely be a real battery juice drainer.


The google search (with quotes) returns 60,000 results, so, yes, it's pretty popular. I mean, common. I mean, common and/or popular. Not exactly witty or beautiful, but pretty popular nonetheless. I mean, common. Yes. Right.

  • Any synonymous phrases that come to your mind? – technophyle Oct 26 '15 at 9:05
  • I don't know ... Juice guzzler? – Ricky Oct 26 '15 at 9:13
  • Sorry I'm not a native speaker, so it's hard for me to distinguish a joke. You're kidding right? – technophyle Oct 26 '15 at 9:24

    Only half-kidding, actually. A car is a gas (petrol, if you will) guzzler if it consumes too much gas (petrol). "Juice" is a slang word for electric power. Thus an application (such as Google Chrome) can theoretically be referred to as a juice guzzler. I'm not sure whether it's popular or not. – Ricky Oct 26 '15 at 9:48
