BIGGER AND BETTER Smart-phone

displays have grown in size and responsive-

ness, increasing versatility and ease of use.

ow important are our

smart phones? Just consider

how much we’re spending

on them. e average Ameri

can household shelled out more than

, on phones and phone service in

, and the biggest spenders easily

blew through twice that amount. Over

all, spending on wireless services was

up by  percent over , even though

many households cut just about every

other expenditure they could.

Part of that spending spree came as

owners of basic cell phones continued

to trade up to their first smart phones,

those Webconnected combinations of

phone, minicomputer, and micro

compact camera. About  percent of

C R readers who re

sponded to our annual survey on cell

phone service now own a smart phone,

up from about  percent only two

years ago.

Upgrading from a plain cell phone at

a major carrier isn’t cheap. You have to

buy the smart phone itself usually

 to  when signing a twoyear

contract and fork over  to  a

month for a plan with data service.

at’s a lot more than a basic phone

plan, which generally costs  to 

a month.

Even if you already own a smart

phone, you might be tempted by the

charms of a later model. e best of

the new phonesincluding the Apple

iPhone  and Samsung Galaxy S III and

Note IIoffer better cameras, bigger

and more responsive screens, and

faster processors for speedier Web ac

cess and app performance.

Data-hogging phone habits

It’s easy to burn through the 2-gigabyte

(that’s 2,000 megabytes) monthly

allowance of typical data plans, especially

if you overdo any of the activities below

when connected to the carrier’s network.

Use Wi-Fi instead of the data network

when possible and limit these activities:

Watching video streams.

A highquality video stream consumes

almost MB per minute with a G connection.

Streaming a video per day from YouTube for a

month, or a single HD movie, could eat up

MB of dataor more than a third of that

GB budget. Use the phone’s settings to reduce

the resolution of videos you watch or upload.

Making video calls.

Facetoface video calls, using the

frontmounted camera found on most new

smart phones, eat up a hefty . to MB a

minute. Chat for  minutes once a week with

your daughter at college and you would use

up at least MB of data per month.

Uploading video.

Can’t wait until a WiFi network is

accessible to upload that highdef video from

your phone to Facebook? Think twice:

Unless it’s compressed, a minute video clip

in HD p can be about MB.

Streaming

music.

Streaming favorite

sounds to your

phone from a

subscription music

service, a collection

stored in the cloud,

or an Internet radio

station eats up a

megabyte of data per minute. Listen for

a halfhour of commuting on weekdays and

during a few minute workouts per week,

and you’ve consumed more than MB of

data in a month. Consider reducing the bit rate

of streams via settings and storing music on

the device rather than streaming.

Playing connected games online.

Shooting it out with other players in

highoctane online games is way cooland

way costly. With every minute of play requiring

a megabyte of data, a halfhour of play three

times a week will easily burn through MB

of data per month.

On the plus side, at least three activities you

might think are data hogs usually use less than

a megabyte of data per minute: surfing the

Web, using maps and navigation, and sending

email at least without attachments. If your

phone has a data usage monitor, check it

periodically to make sure you don’t overdo it.
