Google wants its users getting the most out of their Android devices. To ensure people will continue to tap away at their smartphones, Google showed off Project Volta, a part of Android L focused on optimizing the battery life in every part of Android.

Project Volta consists of three methods that will help developers improve battery performance:

  • Battery Historian: The first is a visual timeline called Battery Historian. The tool is designed to measure battery discharge by helping developers “visualize on a time axis the battery usage information.” This allows developers to pinpoint issues and fix it to improve battery life.
  • Improving battery consumption within apps: A new JobScheduler API has also been added as a part of Project Volta to help improve battery consumption occurring within apps. The API brings together non-urgent network requests from multiple apps to increase efficiency. With the new API, the platform can keep the radio asleep a higher percent of the time to save power. It can also be used to schedule maintenance tasks while the phone is plugged into the charger.
  • Battery Saver mode: The final piece of Project Volta is the new Battery Saver mode. It can be used to clock down the CPU and screen refresh rate, or turn off background data. Battery Saver mode can be triggered manually or set to start automatically when the battery reaches a certain percentage. Google promises the mode can extend battery life by 90 minutes of usage.

Android is getting an AI overhaul. Here’s what it looks like
Android 15 on stage at Google I/O 2024.

At Google I/O 2024, Google has shown off a lot of new improvements coming to Android, thanks to Gemini. With Gemini, Android will be aware of the context on the screen in a variety of scenarios, which will make your life a lot easier. At least, according to Google.

Circle to Search, which was first shown off during Samsung’s Galaxy Unpacked event earlier this year, will be getting some new enhancements. Now, Circle to Search will be a great new study buddy for students. Why? Because it will be able to help with homework, like physics and math. You can simply circle a prompt on the screen, and it will give you step-by-step instructions on how to solve it.

Android, Wear OS, and Pixel may be Google's household names, but it was Google Gemini, its emerging AI technology, that stole the limelight at Google I/O 2024. The company's annual software celebration sets the stage for everything the company has planned for the coming year, and this year, CEO Sundar Pichai unambiguously declared that Google is in its "Gemini era." From AI searches in your Google Photos to virtual AI assistants that will work alongside you, Google is baking Gemini into absolutely everything, and the implications are enormous. Here's an overview of everything Google announced this year.

Users upload more than 6 billion photos to Google Photos every day, so it's little wonder that we could use a hand sifting through them all. Gemini will be added to Google Photos this summer, adding extra search abilities through the Ask Photos function. For instance, ask it "what's my license plate again" and it'll search through your photos to find the most likely answer, saving you from needing to manually look through your photos to find it yourself.

Google Play on the Oppo Find N2.

Google announced a wide range of features for Android phones at the I/O 2024 developers conference earlier today. However, the event was not all about user-facing changes. The company also revealed a handful of new tricks for developers to showcase their apps effectively while maintaining a vigilant eye on safety.

Among the most important changes -- one that is also going to make life easier for users - is support for more payment options. The most notable of these is support for installment subscriptions, which has already yielded positive results for developers in the early access phase.
