iPhone 4 battery dying when phone is at room temperature
Hi I recently have been having issues with my old iPhone 4 and im getting a new phone in august but i want to make the most of it right now so i have been having this issue: My phone shuts off randomly and wont turn on. I have tries battery calibration and i have found out it will turn on when i heat it up with something like a heat pad. I want to know if its because the lithium ion battery heat sensory thing is indicating too cold beacuse the battery is old (6 years) but i just want a fix so i can use it for these 3 months
iPhone 4, iOS 7.1.2
