The Samsung Stratosphere comes packing a removable 1800mAh battery, which can be accessed by using a thumbnail to pry off the entire thin plastic shell covering the back of the unit. Once opened, you'll also find the LTE SIM card slot above the battery and off to the right, space for a micro-SD (4GB preinstalled, up to 32GB supported).
Samsung and Verizon promise standby time of up to 212 hours (just shy of nine days) and usage time up to eight hours (or rather, 480 minutes, which the carrier touts in an effort to impress). We didn't quite reach those lofty heights of usage or standby time, but given the 4G LTE data connection, we have no complaints.
The Stratosphere is also a cost-effective way to tap into Verizon's 4G LTE, since the handset is Mobile Hotspot capable for up to eight devices (five devices over 3G). The device includes 802.11 a/b/g/n Wi-Fi and Bluetooth 3.0 as well.
Speaking of Wi-Fi, the Samsung Stratosphere includes a setting we've not seen before: "Notify me." When toggled on, the device nags you when known Wi-Fi networks are available before consuming high-speed data on one of Verizon's notoriously capped 4G LTE data plans.
Thankfully, this feature is easily toggled off for users who don't want to be bugged each time they want to tap into some LTE goodness.
