I am very dependent on the Sony SWR50 for my ‘Standalone Collector’. It seems to be the perfect device for my application. I do hope that the watch being developed by JamOrHam has the transflective display.
I have even had a former promoter, Verizon, of the SWR50 to try to get Sony to again start production. As yet no success.
I first started using the Sony SWR50 on 7/12/2018, 11:08AM, as a ‘Standalone Collector’. At that time I had more than 50% battery charge after 16 hours of operation.
The reason I need the ‘Standalone Collector’ operation is I am not able to always have my smartphone available, security and environment restrictions. I am also a long distance competitive runner an don’t want the extra inconvenience of a smartphone during a run.
I’m not exactly sure when the battery charge started to reduce. It seems to have happened all of a sudden. I do know that after a complete reprogramming with xDrip and the Wear OS the battery charge again increases to the original level, 50% after 16 hours of operation. After a couple of days it again drops to less than 10% after about 14 hours.
I have replaced the battery in my watch. If you do replace the battery make sure that it matches the original 420 mAh specification. There are some sellers that are selling a 240 mAh battery for the SWR50 that only last about 8 hours before complete discharge.
I did start using my ‘new’ SWR20. Again first displayed more than 50% charge after 16 hours but quickly dropped to less than 10% after 14 hours.
For the SWR50 the battery change is pretty simple. Just make sure that you have the correct battery.
