Can’t decide between the LG G4 and the Galaxy S6? They’re two of the hottest Android devices on the market right now, but LG is hoping it can secure your vote with some useful freebies. For a limited time, the company is giving G4 buyers an extra battery and a 32GB microSD card.

“The LG G4 gives you the power to stay connected with life’s important moments,” LG says. “With an expandable micro SD slot and removable 3,000mAh battery, you’ll get the usage time you need and the extra space to keep all your memories at your fingertips.”

The battery comes in its own charging cradle, so you can keep it topped up even while it’s out of your phone. That means you can plug both devices in at night, and you’ll have two fully-charged batteries to keep you going throughout the day.

According to LG, the battery and microSD card are worth around $105 together, but if you buy a G4 in the U.S. before June 21, you’ll get them both absolutely free. You’ll need to purchase your handset first, then send LG a photo of its IMEI number and a copy of the receipt via its website.
