First, make sure that streamer and paired device isnt too separeted. when i took mobile phone in my room overnight and streamer in another it drained whole phone battery because it was all night reconecting, connecting.
If it under warranty, rma it.
Here are some info on streamer and battery…
A new fully charged battery supports up to 5 hours of streaming time (phone conversation and/or audio) and up to 70 hours without streaming.
To prolong the life of the Streamer’s lithium-ion battery, charge it on a daily basis, and never drain it completely. For more information about the battery, please look at the answer to “Battery – How long can I expect the battery to last?”
Battery life and number of charge cycles vary by use, though you may expect it to last for approximately 2 years.
The lithium-ion battery in the Streamer provides 500-800 charge cycles. A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you can use the Streamer for a few hours one day, using half its power, and then recharge it fully. If you do the same thing the next day, it would count as one charge cycle, not two, so it may take several days to complete a cycle. Each time a charge cycle is completed; it diminishes battery capacity slightly and as with other rechargeable batteries, the battery may eventually need to be replaced.
