Some smartphones list the optimum range of temperatures in their technical specs. When lithium-ion batteries are exposed to cold temperatures, their performance suffers. When cold, a phone battery can drain faster than normal, or it might say it has ample power remaining and then suddenly go dead.

As you’ll see in the pictures below, the cord to plug in your engine block heater is typically found under the hood, and we’ve even drawn a box around where the cord is for your convenience.

Does the cold kill your phone battery? Not permanently, no. Cold temperatures increase a lithium battery’s impedance, which reduces the amount of power it can deliver. The good news is that these effects are only temporary, and your phone’s performance should return to normal once it has warmed up.

Your iPhone or Android phone isn’t designed for freezing cold temperatures under 32 degrees. That means your phone might shut down or lose its charge quickly if you use it outside, even for a few minutes.

Why Your Phone Hates Cold Weather Because they depend on lithium-ion batteries. This type of battery is what powers most rechargeable mobile devices. The battery meter in your iPhone or Android phone is calibrated assuming it will be used in moderate weather (32° – 95° Fahrenheit).

Temperature is probably the most common reason that smartphone batteries die unexpectedly. Internally, there could be a software issue that’s draining your battery faster than normal. This could be an app running in the background, like a mobile game, malware, or even a simple software bug that needs to be patched.

Optimal temperature range Its “non-operating temperature” are below -4 degrees and above 113 degrees Fahrenheit. There’s a small gap between these temperature ranges where your phone will continue to operate, but not at its best. If your phone reaches -4 degrees or 113 degrees, a warning message will appear.
