Google's upcoming changes to Chrome will save your phone's battery

One of the most important features of any phone is how long the battery lasts, and it can be surprising what impacts upon longevity. Over the coming month, Google is going to test changes in the mobile version of Chrome that will not only help to improve battery life, but should also help to reduce data usage.

The changes come after the company has spent time improving Chrome users' online experiences by blocking ads that are considered harmful or annoying. Next in the company's crosshairs are ads that "consume a disproportionate share of device resources".

As part of its audits of ads, Google says that it detected a small percentage that were secretly using network data and draining battery power. Citing examples such as cryptominers, the company says that these types of ads are badly programmed, and a lack of optimisation leads to a poor experience for users.

To help counter this, Google says it is going to place limits on the resources ads are allowed to use. Chrome will restrict how much battery life, how much CPU power, and how much network data any ads is able to make use of. Once this limit is reached, Chrome will simply unload the offending ad.

Blocking bad ads

Google is setting pretty strict limits on what resources ads are able to use – just 4MB of network data or 15 seconds of CPU usage in any 30 second period, or 60 seconds of total CPU usage. Google's analysis shows that a mere 0.3 percent of ads currently exceed these limits, the impact they have is pretty huge. This tiny percentage of ads accounts for 28 percent of all ad CPU usage and 27 percent of network data by ads. This is precisely why Google is so keen to take action.

The company says that it will start its experiments in blocking "heavy" ads over the next several months. The aim is to include the resource-saving feature in the stable version of Chrome that will be released towards the end of August, so before summer is out you may start to see an improvement in your phone's battery life and a decrease in data usage.
