Tips to keep iPhone 4S battery from draining fast

People have found that the "Setting Time Zone" element operates when it doesn't need to, draining the battery

Apple iPhone 4S users worried about the device’s battery draining rapidly can take steps to prevent the problem.

Here’s a rundown of what may be causing the problem and how you can fix it.

It appears that the location services system in iOS 5 is one issue that has something to do with it.

A growing number of people have found that the "Setting Time Zone" element within Location Services in iOS seems to be operating when it doesn’t need to be, resulting in excessive battery drain.

To stop that from happening, go to Settings > Location Services > System Services. From there, it’s just a matter of turning off “Setting Time Zone.”

Switching it off may mean that your iPhone will no longer set its own time zone when you travel, but that’s a small price to pay for dramatically increasing the life of your iPhone charge, notes iDownload, which tested this method on several iPhones, including the 4s, iPhone 4 and an iPhone 3GS, all of which demonstrated drastically improved battery life after making the change.

So far Apple hasn’t commented on the issue but The Guardian reported on Friday that its engineers have begun contacting some people who have been reporting exceptionally rapid battery depletion.

The time zone setting might not be the only problem.

Macworld found that contact syncing within iCloud also increased battery drain. In that case, wiping the phone and then syncing via iCloud solved the problem.

A PCWorld reader had a similar problem with a new iPhone 4S and took it to an Apple store. An employee ran a diagnostics check on the device. He stated that the process that allows the cellular connection was in a constant crash reboot state and it was eating the battery. The employee wiped the phone and asked the user to not restore from backup but to just do a sync to the device. After performing these steps, the phone has performed well.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
