In November, OnePlus officially launched the OnePlus 3T, their newest flagship smartphone for 2016.

Now, just about a month later, the company has announced a new software update for the device rolling out beginning today. It will upgrade OxygenOS to version 3.5.4, and it primarily focuses on performance enhancements and tweaks, including making sure the device doesn’t lag when it drops down to 5% of battery or less, and more.

The other big addition is optimizations put in place to work with the T-Mobile network in the United States.

Here is the full changelog:

• Optimizations for US-TMO Network
• Optimizations to Reduce Lag when Battery is below 5%
• Optimized Bluetooth Connectivity for Mazda Cars
• Optimized Battery Saving Mode: GPS and Orientation Preferences will be restored when Battery Saving Mode is closed.
• Fixed Flashlight Usability Issue in WhatsApp
• Increased System Stability
• Implemented Various Bug Fixes

The software has begun its global rollout now, but as with any over-the-air (OTA) update, it might take some time to arrive on your handset.
