WhatsApp announced the launch of WhatsApp Web on Wednesday, finally enabling the use of the popular messaging app on desktop computers. While the solution isn't cross-platform and feels like a hack at first glance, it works surprisingly well. We managed to get our hands on the updated Android app that comes with WhatsApp Web support, and here are our initial thoughts.

The first step towards getting WhatsApp working inside your browser is to get the latest version of WhatsApp for Android, BlackBerry, Nokia S60, or Windows Phone (sorry iPhone users) that comes with support for WhatsApp Web. Look for the WhatsApp Web option in the respective apps before proceeding further - the WhatsApp Web website tells you where to find the option inside each app. Android users, make sure you are running version 2.11.498 or later. To check what version of WhatsApp you are on, open the app, go to the menu (three dots) ->Settings ->Help ->About.

Next, open the whtsapp Web Website on your desktop in Google Chrome. This is important as there's no standalone desktop app for WhatsApp and WhatsApp Web will not work in any other browser like Safari, Firefox, or Internet Explorer. Once the WhatsApp Web page finishes loading, you will see a QR code on the top left part of the screen. Now fire up WhatsApp on your mobile phone and select WhatsApp Web from the menu (three dots).

The WhatsApp Web UI will look familiar to all WhatsApp users. You can of course joining existing conversations (including groups) or initiate new ones. Features like delivery and read receipts are supported, and you can also share pictures (stored on your computer, or by clicking a fresh one using your webcam) as well as voice messages without needing to touch your phone. Everything worked as expected during our testing.

One thing worth noting is that WhatsApp Web uses your phone's Internet connection to send and receive your messages, so your mobile needs to be connected to the Internet throughout, either via Wi-Fi or cellular data. In that sense, WhatsApp Web is different from other messaging apps like Skype and Viber where every device has its own connection to the servers. This is an example of WhatsApp keeping it 'mobile first', which may not appeal to everyone, but is central to WhatsApp's philosophy.

You can initiate WhatsApp Web sessions from multiple computers, but only one can be active at a time - you'll be given an option to wrest control from another session. WhatsApp takes care of the security aspect by listing how many WhatsApp Web sessions are connected at any given time, and by letting you log out of all in one click via the mobile app.

Overall, while WhatsApp Web may seem like a hack at first - what with its use of QR codes and everything else - if offers everything you'll need for a complete(ish) WhatsApp experience on the desktop, as long as your definition of desktop is Google Chrome. Now there's no real reason for us to ignore those lovely WhatsApp forwards while working, except of course the fact it doesn't work with the iPhone. If you are a fellow iPhone user, don't hold your breath, as WhatsApp co-founder and CEO Jan Koum says, "for now, we will not be able to provide Web client to our iOS users due to Apple platform limitations."

Tip #1: Seek Out Battery Hogging Apps

Tip #3. Disable Auto App Updates

Even though I love this feature, it does drain my battery. Instead of having your apps automatically update when there is an update available, you can turn this off and set it to update only when you want to manually.

Go to Settings -> iTunes & App Store, then disable Automatic Downloads for apps listed there. At the very least, toggle off the "Use Cellular Data" option so that apps only auto-update when you're connected to Wi-Fi.

I suggest performing all of your updates manually at night while the device is charging. Just go into the App Store app, head to the Purchased tab, and select Update All.

Tip #4: Control Background App Refreshing

"Turning off apps may help preserve battery life" is exactly what Apple says in their Background App Refresh section. So, let's take their advice and turn off apps we don't need to have refreshing in the background. This is really important if you have a lot of apps installed.

Go to Settings -> General -> Background App Refresh, then start turning off apps like Podcasts, Stocks, YouTube, etc. that you don't need running in the background when you aren't using them.

Tip #5: Turn Off Location Services

It makes sense that Location Services is a pretty big battery drainer. While one-hundred percent necessary for apps like Maps, Tinder, Waze, and Yelp, among others, there are some apps that really don't need to access your location at all.

Head to Settings -> Privacy -> Location Services to see a list of apps with the ability to access to your location.

Why would I want OkCupid to Always have access to my location? I might be single, but come on.

You can change an app's location access by selecting it, then choosing between Never, Always, and While Using. These options are new to iOS 8, as previously we could only select ON or OFF.

There aren't too many apps that need the Always setting, so make sure to switch those to While Using or Never—the fewer apps you have using Location Services, the longer your battery will last.

And if you really want to save some battery life, you can turn Location Services off completely, but would require that you manually turn them back on when using apps like Maps.

Tip #6: Turn Off Share Your Location

Another goodie included in iOS 8 is the ability toshare your current location with friends or family within the Messages app.

When enabled, you can share your location by selecting Details inside a message thread, then choosing how long you want your location to be shared.

While this could be helpful for meeting up with people on-the-move, the feature will also take a toll on your battery life.

It can be disabled by going to Settings -> Privacy -> Location Services ->Share My Location, or you could just send your location once (or occasionally) so that your device isn't constantly polling for your whereabouts.

Tip #7: Disable Location-Based iAds & Alerts

Another possibly helpful, but more-so creepy, addition to iOS 8 is Location-Based Alerts. Apple sends you alerts from retailers, banks, and stores near your current location, informing you about their app. These alerts appear on your lock screen, opposite the Camera icon.

While I appreciate the effort to woo me into installing the Ralphs app, I'm also slightly creeped out by this "feature." Same goes for Location-Based iAds—I mean, they're no different from what Google does with your search history, but still, I don't like it.

In order to disable both of these options, go to Settings -> Privacy ->Location Services -> System Services, then toggle one or both of them off.

While disabling these will certainly help with battery drain, for me, it's definitely more of a privacy issue. Make sure to check out these 14 privacy settings that you'll want to get familiar with in addition.

Tip #8: Adjust Screen Brightness

A tried-and-true battery saving tip, you can adjust the brightness of your device by pulling up the Control Center, or going to Settings -> Display and Brightness and adjusting from there. The lower you have it, the less drain of your battery.

You might have seen people telling you to toggle on Auto-Brightness to save battery, but I'm not fully sold on that. Since your device will constantly be adjusting to the lighting around you, this feature could potentially be draining more battery.

In my experience, it's best to set your brightness at a low, but comfortable level, and manually adjust up as needed.

Tip #9: Make Sure AirDrop Is Off

AirDrop is nice when you need it, but more often than not, you won't.Introduced in iOS 7, this feature makes it easy to send pictures, contacts, memos, locations, and more with nearby devices. AirDrop uses both Wi-Fi and Bluetooth to make this possible—both of which can be big battery drainers.

Simply put, when you're not actively using it, turn it off. Just pull up the Control Center, tap AirDrop, then select Off.

Tip #10: Turn Off Bluetooth & Wi-Fi

This is a no-brainer for anyone hoping to squeeze the most out of their battery life—turn off Bluetooth and Wi-Fi when you don't need them. Bring up the Control Center and toggle each of them off.

Tip #11: Turn Off Parallax "Motion"

While it may look cool, especially if you're just entering the world of iPhones, Motion (or parallax effect) doesn't really do anything for you.

The parallax effect uses hardware to sense the direction, speed, and motion of your movements, then adjusts the display accordingly. For all intents and purposes, this is really nothing more than a battery drainer, since all those sensors are constantly working to relay motion.

Turn the parallax effect off by going to Settings -> General -> Accessibilityand toggling on Reduce Motion.

Tip #12: Don't Use Dynamic Wallpapers

Here's another good-looking option that sucks the life out of your phone. While Dynamic Wallpapers are appealing—using subtle effects to make them "dynamic"—it's hard to argue that they are worth the battery suck.

Instead, use any of the millions of images available to you online, or take your own with the camera. Apple also provides a bunch of still images that can be used as wallpapers, and you can also make your own with these guidelines.

Tip #13: Disable LTE When You Can

Faster LTE speeds require more battery consumption from your phone's cellular radio. It's the give-and-take we have all become accustomed to. If you can handle the slower speeds of an Edge or 3G connection, then this is another way to increase your battery life.

Head to Settings -> Cellular -> Enable LTE and toggle it off.

Tip #14: Close Running Apps

This is another debatable tip. You know when people tell you that constantly turning your car on and off when its idle is actually worse than just leaving it running? This is similar to that line of thinking.

If you are not using an app anymore, then you might as well close it out. Just double-press the Home button and flick up to close out an app completely.

Tip #15: Go Fetch

While the obsession of needing to know the instant a new email gets in is not lost on me, if you're serious about saving battery life, you will need to take a different approach.

Most people have their mail set to Push, which automatically sends new data whenever it is available. That means that your phone is constantly polling your email provider's servers to see if anything new has arrived, which can take a hit on battery life.

Go to Settings -> Mail, Contacts, Calendars -> Fetch New Data and toggle off the Push option. Then make sure that you set all of your apps to Fetch, then adjust the Fetch schedule—the less often you Fetch, the more battery life you save.

Thank You..
