Battery Optimizers for Android and iOS

With increasing RAM, storage and processing power, the only aspect of smartphones that is still lagging behind is the battery life. Sometimes, it can be such a huge problem which may takes away the fun and sophistication of the smartphone experience. And of course you can't even enjoy all the other good stuff that many phones come with.

Why smartphones always drain the battery fast?

Although Android and iOS devices have different systems, but their users still suffer from similar issues when it comes to battery life. Here are some of the top battery juice guzzlers on both operating systems:

- Screen brightness
The entire face of any smartphone is the screen, and this has to be powered by the battery. Some screens seem to have a lot of pixels, which despite producing crisp image quality take a toll on the battery. Naturally, higher brightness means increased use of energy and thus your battery drains faster. To prevent this, try to keep the brightness as low as you can while you're outdoors and perhaps even turn it all the way down while you're indoors. Avoid the "Automatic Brightness" option because it can raise brightness to levels you may don't need.

- GPS
Used for locating you on the map, GPS adapters are in constant communication with satellites and consequently they drain your battery also. The constant pinging by your device will definitely shorten the battery life. On the iPhone, you can set Location Services to only be available when needed. In that way, you will still be able to use the Maps app, but GPS services will be off when you close the app.

- Automatic updates
When this option is opened on your device, all apps will be updated, downloaded and installed on your device automatically. And of course, this process will cost lots of power on your mobile phones. So it is really recommended here to disable the automatic update function on your device for the security and power-saving considerations.

In addition to the above settings, here we also picked up several battery optimizers for Android and iOS devices. You can compare them and decide which one is better according to your own needs.

Top 5 Battery Optimizers for Android & iOS Devices

Battery Doctor (Battery Saver)

This app monitors how you use your device and provides an accurate estimate of the time you have left. If you would like to, you can choose to close some of the apps that are not in use. However, Battery Doctor does that automatically when the device is idle, ensuring your battery lasts much longer.

Avast will detect any opened apps and close them if they are already too resource intensive. The choice of which apps and when they're closed will be given in the set profile, and you determine exactly how many apps you want running at a given time.
