Data usage on a smartphone.
In the early days of cell phones, it was all about the minutes -- voice minutes, that is, because people used their phones to call each other. (Weird, right?) You had to limit your conversations or suffer the horrors of overage charges.
Whatever
your plan, it makes sense to conserve data. And what's the easiest way
to do that? Connect to Wi-Fi wherever and whenever possible. Sure, it
takes a few extra taps to connect to a network in, say, a coffee shop or
airport lounge, and you make feel like it's not worth the hassle if
you've got five 4G bars showing.
Depending on what you're planning
to do with your phone, however, it may absolutely be worth it. Here are
five of the biggest data hogs you want to avoid (or at least reduce)
when there's no Wi-Fi available:
1. YouTube uploads
Just
can't wait to share that epic video of your friend wiping out on his
skateboard? Or your totally legit Bigfoot sighting? Upload at your own
risk: Depending on settings and various other factors, each minute of HD
video you shot can be as large as 200MB.
So if you upload just
five 1-minute videos per month, that would eat a full gigabyte of your
data allotment. Wait till there's Wi-Fi!
2. Video chats
Stop
the Skyping! And the FaceTiming. And all the other video calling -- if
you want to save data. Though the rate of consumption varies depending
on the app you use and resolution of your chat, a Jetsons-style phone
call can cost you up to 3MB per minute.
3. Online gaming
Don't
worry, Trivia Crack addicts, turn-based games like this and Words With
Friends aren't heavy data-users. However, real-time action games like
Asphalt 8 and Modern Combat 5: Blackout are a different story, with some
estimates pegging their data use at 1MB per minute of play.
4. Music streaming
It's
so easy (and awesome) to plug into Pandora or Spotify when you're, say,
riding the train home from work, you might not realize what it's doing
to your data plan.
What it's doing is killing your cap. If a music service streams at a 320Kbps bit rate, that's 2.4MB of data per minute,
or a whopping 115MB per hour. Even if you tune in only a couple times
per week, it's easy to rack up big data numbers. Fortunately, a lot of
mobile apps let you downshift to a lower bit rate, a very advisable move
if you must listen on the go.
Pandora, it's worth noting, never streams at more than 64Kbps on mobile devices, even if you're a Pandora One subscriber.
One
other option: if your music service allows it (and most do nowadays),
download your tunes (via Wi-Fi, of course) for offline listening.
5. Video streaming
If
music streaming is bad, video trumps it by an order of magnitude.
Awesome though it may be to binge on episodes of "Black Mirror" or
trending YouTube vids when you're on the treadmill at the gym, streaming
can swallow as much as 50MB per minute.
That's according to Netflix,
which estimates 3GB per hour for HD video. Of course, those numbers can
and will vary across different services (Hulu, Google Play, iTunes, YouTube, etc.), but there's no question that video does the most damage to your data plan.
Fortunately,
with a little advance planning, you can watch on the go without using
any data at all. Consider a service like PlayLater, which allows you to
"record" streaming video from the likes of Hulu and Netflix for offline
viewing on mobile devices. Likewise, a smattering of YouTube apps let
you save videos right to your phone so you can rewatch them later -- no
connection required.
