The following happened to me today, and once before a few weeks ago. I checked my Tandem t:slim X2’s battery, and it was reading at (I think) 35 or 40%. I decided to take advantage of a computer session, and plugged it in. Some time later (I wish I had noted down the time), I checked it again, and it was down to 5%! While being charged!
I let it keep charging, and it built back up to 45% at the usual rate. I went out for a walk, and came back and plugged it in. In about five minutes, it was showing 100%!
The first time a similar event took place, I emailed Tandem Customer Service. A tech got back to me fairly quickly. She told me this was not unusual, and mentioned that some users make it a practice to charge the pump for a few minutes every day, just to make sure it’s OK.
This seems wrong to me. We should use a workaround to make up for defective technology?! And we can’t trust the battery level number displayed?! That’s something that seems like it should be fixed! I’m going to try to record this so I have some data to submit.
Now: normally I get several days, over a week, on a charge. So it’s not like the battery is failing. It’s just the level display seems to get stuck at too high a reading for a while, until you plug in the charger, whereupon it drops down to the correct–low!–level. Or maybe it’s the LOW reading that is incorrect! How would I know?!
Anyone else have a similar experience?
