The bright secret of battery life

Published

on

On most smartphones in active use, batteries last little more than half a day. But there is a simple secret to the real battery hog, and how to double that life, writes ARTHUR GOLDSTUCK.

You know how it goes when you first get a new smartphone. Battery life is amazing for the first few days, often lasting well into the night. Then, as you download more apps and use them actively, you find yourself scrambling for a power bank or charging point by lunchtime.

We keep hearing that battery life is the next frontier of smartphone technology, and then we keep seeing dramatic advances in every aspect of the handset BUT battery life.

In the good old battery days of a decade ago, a Nokia 6310i gave you seven days’ talk time and a month on standby. The rapid advance of smartphone technology has meant that average battery life has rapidly gone down, instead of increasing, because so many more components and functions have been built on the same old batteries.

The Nokia 6310i featured a talk time of up to a week.

Now, however, battery management functions, such as those on new Samsung, LG and Huawei devices, help to identify which apps drain the most power, and to shut down the offending tools.

But, strange to say, this doesn’t keep our phones going longer. As we keep opening new apps that we hope are less demanding, or keep open some of the apps that are indicated as having low power demands, the battery drainage continues at the same high rate.

This happens particularly while one is driving, and using navigational apps like Waze and Google Maps. The assumption that tends to be made is that it is not the app itself that is resulting in heavy battery use, but the need for the maps to be updated continuously. This results not only in an ongoing data flood, but also requires the phone to keep polling the 3G or LTE masts at base stations along the route. Surely the prime reason the battery is dying!

Android power management apps help increase battery life.

The truth is a little simpler and a lot closer to home.

The reason Waze appears to chew up battery life faster than a puppy destroying a slipper is because it keeps alive the real battery hog: the screen display.

Check that battery management tool again: it can almost be guaranteed that half the battery usage in any given period is coming from the display. The bigger the screen, the more the display demand, and the faster the battery drain.

For this reason, entry-level smartphones with 3.5-inch screens tend to have far more battery life than the average 5-inch or 5.5-inch flagship devices. Compact editions of the Samsung Galaxy and Sony Xperia phones last longer than their bigger siblings. This is counter-intuitive merely because we expect to get better performance when we pay more.

The exception to the rule appears to be the giant-sized phablets: the 5.7” to 6” behemoths. But there is a simple reason for that, too. Most of these phones have oversized batteries, specifically to compensate for the giant displays.

It’s not an industry secret, either. Manufacturers continually point out this truth, but usually in the small print, as an afterthought, or somewhere offstage after the big launch.

All of this means that there is also a simple secret to extending battery life, while we wait for the scientists and engineers to catch up to our needs.

Every time you finish using the handset, whether for a call, a WhatsApp message or a Facebook peek, simply click the On/Off button briefly – that is, not long enough to switch off the phone, but merely to turn the display dark.

If that doesn’t at least extend your battery life into the evening, something else is going wrong with the device, or a rogue app is indeed going puppy on the battery slipper.

How we use phones to avoid human contact

A recent study by Kaspersky Lab has found that 75% of people pick up their connected device to avoid conversing with another human being.

Published

on

Connected devices are becoming essential to keeping people in contact with each other, but for many they are also a much-needed comfort blanket in a variety of social situations when they do not want to interact with others. A recent survey from Kaspersky Lab has confirmed this trend in behaviour after three-quarters of people (75%) admitted they use a device to pretend to be busy when they don’t want to talk to someone else, showing the importance of keeping connected devices protected under all circumstances. 

Imagine you’ve arrived at a bar and you’re waiting for your date. The bar is busy, and people are chatting all around you. What do you do now? Strike up a conversation with someone you don’t know? Grab your phone from your pocket or handbag until your date arrives to keep yourself busy? Why talk to humans or even make eye-contact with someone else when you can stare at your connected device instead?

The truth is, our use of devices is making it much easier to avoid small talk or even be polite to those around us, and new Kaspersky Lab research has found that 72% of people use one when they do not know what to do in a social situation. They are also the ‘go-to’ distraction for people even when they aren’t trying to look busy or avoid someone’s eye. 46% of people admit to using a device just to kill time every day and 44% use it as a daily distraction.

In addition to just being a distraction, devices are also a lifeline to those who would rather not talk directly to another person in day-to-day situations, to complete essential tasks. In fact, nearly a third (31%) of people would prefer to carry out tasks such as ordering a taxi or finding directions to where they need to go via a website and an app, because they find it an easier experience than speaking with another person.

Whether they are helping us avoid direct contact or filling a void in our daily lives, our constant reliance on devices has become a cause for panic when they become unusable. A third (34%) of people worry that they will not be able to entertain themselves if they cannot access a connected device. 12% are even concerned that they won’t be able to pretend to be busy if their device is out of action.

Dmitry Aleshin, VP for Product Marketing, Kaspersky Lab said, “The reliance on connected devices is impacting us in more ways than we could have ever expected. There is no doubt that being connected gives us the freedom to make modern life easier, but devices are also vital to help people get through different and difficult social situations. No matter what your ‘connection crutch’ is, it is essential to make sure your device is online and available when you need it most.”

To ensure your device lifeline is always there and in top health – no matter what the reason or situation – Kaspersky Security Cloud keeps your connection safe and secure:

·         I want to use my device while waiting for a friend – is it secure to access the bar’s Wi-Fi?

With Kaspersky Security Cloud, devices are protected against network threats, even if the user needs to use insecure public Wi-Fi hotspots. This is done through transferring data via an encrypted channel to ensure personal data safety, so users’ devices are protected on any connection.

·         Oh no! I’m bored but my phone’s battery is getting low – what am I going to do?

Users can track their battery level thanks to a countdown of how many minutes are left until their device shuts down in the Kaspersky Security Cloud interface. There is also a wide-range of portable power supplies available to keep device batteries charged while on-the-go.

·         I’ve lost my phone! How will I keep myself entertained now?

Should the unthinkable happen and you lose or have your phone stolen, Kaspersky Security Cloud can track and protect your device from data breaches, for complete peace of mind. Remote lock and locate features ensure your device remains secure until you are reunited.
