Help Nexus 7 won't charge wirelessly any more

OK here was the culprit.
I had notice what I thought was a slight position sensitivity when placing the tablet on the charging coil, but it turns out it was slight *pressure* sensitivity.
The battery is original, and performs fine, but the tablet had been left on the patio (in Arizona) and so it overheated. There was not a slight bulge to the back cover. Opening the unit revealed the LIon battery envelope was "ballooned".
The "ballooned" battery pressure was pushing the back cover away sufficiently that the small "S" shaped contacts to the charging coil on the back cover were intermittently making contact to the main circuit board.
A temporary fix was to slightly "stretch" the "S" contacts. This worked reliably for the week it took to get a replacement battery. Prior to the battery replacement there was a noticeable bow to the back cover, but also a slight bow (about 1mm) to the actual display...which was scary. With the new battery everything is back to normal.
Thanks, all, for your helpful relies.
Thank you for this post! Fixed my mystery issue... The NEXUS 2013 will never die!
Still so hard to find a tablet with Wireless Charging. LineageOS has mine running Android 11.
