Question 1

If I wanted to buy more batteries, what kind do I buy?

Accepted Answer

CR1632

Question 2

What is the max. range one can be away from the phone?

Accepted Answer

Range depends on the Bluetooth class of your smartphone.  Bluetooth comes in 3 classes. Ditto and most computers are class 1, with a 100 mW transmitter.  Most keyboard and mice are Class 2 or 3, where class 2 is 2.5mW and class 3 is 1 mW, and hence the common belief that bluetooth is limited to about 30 feet. The iPhone 6 is class 1, but earlier iPhones were class 2 to reduce power consumption.  The maximum range for two Class 1 devices to communicate is about 330 feet.  390 feet is possible in say a desert where there are no obstructions and the air is dry.  2.4 GHz signals are absorbed by water including humidity in the air.I get signal anywhere in the house, and when I am on the driveway with my iPhone 6 at my desk on the opposite side of the house.  Too much range can be a disbenefit because you won't get notified that you left your smartphone behind until you back out of the driveway.  Ditto doesn't notify you that you left your smartphone behind as soon as it loses signal because that would be annoying for momentary losses of signal that probably occur throughout the day from interference.  Microwave ovens, some wireless phones, other bluetooth devices and wifi 802.11bgn all use the same 2.4 GHz radio band.

Question 3

Not tech savvy, using Ditto with my phone, is that considered streaming?

Accepted Answer

It's paring a device like speakers or a headset. Streaming is more widely used term for downloading music and video to devices.

Question 4

How long does the battery last?

Accepted Answer

The battery should last 3-6 months, depending on use. When its time to replace it, you'll get a message telling you it's time for a fresh CR1632 lithium coin cell, available at many pharmacies or online.
