I saw a fair amount of Reddit and Quora posts on whether cooling a phone in a fridge or freezer damage the lithium-ion battery but they give contradictory answers without any evidence or scientific grounding. Does cooling a phone in a fridge or freezer damage the battery?

Reviving a Li-ion battery in freezer? mentions that freezing a battery is deleterious to the battery. How about just using the fridge instead freezer, or using the freezer without freezing the battery?

    $\begingroup$ Depends on the specific chemistry and electrolytes. Storage down to -20C is not an unusual rating. Actual battery performance there will be terrible, which is why lithium batteries for outdoors use come with self-powered heaters. $\endgroup$

    $\begingroup$ Such cooling can damage in long term the phone itself by water condensation and corrosion. $\endgroup$
