BlackBerry has released a firmware update (the first actually) for the Z10. This update addresses a number of issues including battery life. The update is 150MB in size and is available over the air and also includes over 60 optimizations.
3rd Party App Performance
We’ve improved performance for 3rd party applications, so developers can build apps that run fast and smooth for you. With this update, you might want to keep an eye out for some fresh new app launches in March, like WhatsApp.
Phone, Calendar, and Contacts
Among the top improvements and features are fixes for Gmail calendars on BlackBerry 10. You’ll also find improvements in the BlackBerry Hub for logging calls log and how conversations are handled. We’ve also made general improvements to importing contacts from online sources.
We’ve optimized the camera for better photos in low-light situations. You’ll love the difference this makes for photos where you don’t use a flash – like the Time Shift Camera feature.
Browser and Media
With more and more of you using the gorgeous screen on the BlackBerry Z10 to consume online videos and media, we’ve made a number of improvements to the software in the way the browser handles video playback to provide a fantastic experience.
The software team has included a number of battery life optimizations with over 60 battery saving improvements since launch to keep you moving. These combined improvements are designed so that you see improvements in battery life and heavy users especially should see a longer average usage per charge cycle.
