No, the unit was not left on the USB charging cable. I know that there was no impact force to the unit for certain unless something happened to the unit in the factory or shipping, nor has it been over charged and never has been over-discharged. The charger is a standard 2 amp phone charger that is used with other devices without issues. If using the Pinetab for normal use, such as an e-reader causes it to run at high temperatures, than that would be an issue for Pine64 to figure out. My Pinetab has had very light use.
@ImaPagan Did you leave it on charge? If so, using USB or DC barrel jack?
I also own a PineTab and have had no issues so far. I'm using mine for a few hours at a time and generally keep the battery between 50-90% (although a few times 0%). I'm using mine twice a week or so at least.
I have some experience with LiPo batteries and they tend to bloat in such a way if they are over-charged, over-discharged, charged at too high a current, discharged at too high a current, receive impact force or run at high temperatures. I would suggest to look for one of these conditions.
Also, I went ahead and submitted a ticket just to let Pine64 know of the issue. I was a bit surprised that they responded, since there have been complaints about lack of responses posted to the forum. They asked me to open up the Pinetab and take some photos, which I did. There is just a slight swelling noted on the edge of the battery nearest to the CPU. To my untrained eye it doesn't seem like much, but it may have been enough to crack the display. As in my original post, I offered to send the unit back to Pine64 for them to investigate further. I will post a follow up when there is news.
