Ive had my Fairphone 4 since the release. The battery hasn’t been great lately, and I’m considering getting a new one. The main issue lately had been that anytime it gets slightly cold, the battery basically dies immediately. Even in 10°C weather, if I’m outside for too long it died even though it’s at 50%. Yesterday I hat to take the battery out and put it up my sleeve to warm it up a bit, to get my phone to turn on. I was just wondering if this is a common issue? I dont recieve any of the warnings about temperatures being too low, it just dies. I don’t know a lot about phones, so I don’t know if it really is the battery or the phone itself that gets too cold, so I don’t know if a new battery would fix it? Has anyone experienced something similar?
Welcome to the Fairphone community.
Most rechargeable batteries loose power when the temperature drops. In addition old batteries are not able to deliver higher currents, when the phone is asking for it. So what you are experiencing is a quite common issue.
As a battery is easy to swap and quite cheap compared to other phones I would surely give it a try.

Here we talk about 10 °C so it should not have such a high impact.
But you saw, that is has this impact? On an already weak battery?
My FP3 doesn’t have a huge difference of battery at 10 °C or at 20 °C. And its battery is quite old now (since release).
I would understand if it was -10 °C instead of 10 °C.
When in a real pinch, an old trick may be helpful: warm the battery with your body heat. The warmest places to squeeze out some remaining current are the armpits and the crotch. The latter is usually impractical (duh), but with clothes buttoned at the front, you can get inside the outer layers of clothing. For an emergency, warming the battery may work as a last resort, but you might want to buy a fresh battery and/or a power bank.
