Recently, I discovered yet another new piece of the browser puzzle, in the form of a small battery icon found in the Opera toolbar. That icon is for the Battery Saver, a new feature that pulls some interesting little tricks behind the scenes.
What does Battery Saver do?
The Opera Battery saver does the following things:
Reduces activity in background tabs
Tweaks video-playback parameters
Those five items go a long way to saving your battery, especially when your web browser handles the majority of your workload. This is especially true when every little drop of power is crucial to getting you through the day.
Understand that the Battery Saver icon only appears when your laptop is unplugged. The second you plug it in, the icon disappears. Why? Because when you unplug your laptop (and you have Opera open), the Battery Saver mode automatically kicks in. It doesn't matter if your battery is at 100% or 1%, Battery Saver mode will be enabled the second you unplug the laptop.
However, even with the icon appearing in your browser, it doesn't mean Battery Saver mode is on. If the battery icon is black, the mode is off. If the battery is blue, the mode is on. Fortunately, the developers have made it such that you can configure a few parameters to tell Opera when to automatically switch on Battery Saver mode.
Let's do just that.
How to configure Opera's Battery Saver mode
What you'll need: The only thing you'll need for this is an updated version of Opera installed on a laptop. That's it. Let's save some battery.
1. Open Opera
The first thing to do is open the Opera browser. Of course, if you're reading this, chances are pretty good that you already have it open.
2. Open Battery Mode settings
Click the Battery Mode icon. In the resulting popup, click the gear icon in the upper right corner.
3. Configure Battery Mode
The first thing you'll want to do is enable Battery Saver by clicking the top On/Off slider until it's in the On position. Next, click the On/Off slider for Save battery automatically until it's in the On position. Once you've done that, click that drop-down and select from these options: when unplugged, at 80% battery, at 50% battery, or at 20% battery. If you want to get the most out of the Battery Saver mode, select when unplugged. If you're not that concerned about Opera draining your battery, you might select at 50% or at 20%.
Once you've taken care of that, close the settings window and you're done. Opera's Battery Saver mode will automatically kick in at the point you've configured and will help you make it to either the end of the day or until you can reach a plug.
