Replacement battery reported "overheat" and won't charge

I replaced an old battery with the one I got from ifixit in my Pixel (original) phone. Now I have a really hard time charging it because, apparently, it’s reported as overheated, although it’s never even warm to the touch. The only way I’ve been able to charge it so far is to put the phone in the freezer and charge without turning the phone on. Once on, it will not take any charge and is stuck on whatever charge it had before turning on. The battery is reported “overheat” pretty much all the time, even when not charging.

I am convinced I ordered the correct battery and did not make any mistakes when replacing it. It seems like a deficient temperature sensor on the battery. Any ideas?

Well, here are some ideas to that might help those facing the same problem. I can consistently charge the phone when it’s chilled, which is a confirmation of a problem with the battery temperature management. It’s either the temperature sensor/circuitry on the battery that is out of whack, or a charge controller which misinterprets the (correct) data from the sensor, possibly damaged in the process of opening the phone (heat damage). Either way, this can’t be helped easily.

For what it’s worth, the battery did not seem to be OEM, although the same format and appearance, the writing on it was all Chinese, while the original one was in English. There might be some incompatibility between the two.

Had same issue. It's looks like I cracked some small SMD resistor near battery connector (1K value). Soldered larger size SMD resistor with thin wire (can't find same size, only 0805), and tremperature started to read correctly (checked with Accubattery app). Hope it helps.
