It is not as bad as catching on fire but definitely a major defect. On my phone it has issues at 40 degrees F and lower and at about 30% charge.

Apple will replace the battery on certain 6s models but only certain serial numbers. Apparently it impacts the iPhone 6, 6s and 7 (some models). This is a pervasive issue but Apple refuses to address it. If you replace the battery it will address the problem but Apple should issue a recall. Each phone is impacted differently depending on your charging habits. I have seen some graphs generated on the issue. I think after charging a couple hundred of times is fairly typical. It happens after the battery has been recharged many times.

It may be hardware and/or software issue in their phones. This is why we focus so much of our quality testing on battery life- every used iPhone has been tested to ensure a healthy battery. Apple has gone so far as to launch a battery replacement program for the iPhone 5. It’s no secret that your phone’s short battery life might be the result of something more than bad weather. Update: January, 2016: If it is more than just cold weather… We suggest checking out the Anker PowerCore+ mini, which can add over 14 hours of battery life to your iPhone. If all else fails, you may want to bring an external charger with you when it’s extra cold just in case your phone unexpectedly dies on you mid-day. Avoid exposing it to the cold air unless absolutely necessary. This means keep it in a warm pocket – your hands will thank you too (it’s too cold to be walking and texting anyway!)Ī case may help the phone retain some heat as well, just like a coat keeps you warm in the cold weather. To keep your phone working as long as possible while it’s cold outside, the best thing you can do is to keep it warm. Keep your phone alive as long as possible This is one of the reasons your phone may die while still showing 30%.
While we almost never reach the upper range in Canada, temperatures below freezing are typical for the winter months.īecause the battery meter is calibrated assuming warmer temperatures, the reduced capacity in the cold can cause the reading to be unreliable. Specifically, they estimate that at -18 degrees Celcius a Li-ion may only deliver 50% of its capacity.ĭuring last winter’s Polar Vortex, Global news did an experiment which showed an iPhone left outside dropped 14% in only 30 minutes, while an identical phone left inside dropped only 1%.Īpple specifies that their batteries work best at a range of 0 degrees Celsius to 35 degrees Celsius. Lithium-Ion batteries suffer in extreme cold temperatures:Īccording to Battery University, cold temperature “ increases the internal resistance and diminishes the capacity” of a Li-ion battery. Li-ion batteries carry certain advantages – they charge fairly quickly and don’t need to be completely depleted before recharging (in fact, it’s better to recharge at 20% than waiting for your phone to die). Unfortunately, these batteries don’t do so well when the temperature outside drops. This is the most common battery technology found in rechargeable devices. Winter weather can be beautiful, but a dead iPhone is a sad thing The iPhone BatteryĪll iPhones use a type of battery called Lithium-Ion (sometimes abbreviated Li-ion).
