Hi there, I have a iPhone se that I quite like but is now subject to periodic crashes, presumably due to the decline in the health of the battery. It’s nearly 5 years old but otherwise in good condition. The only thing I dislike about the phone is it’s rapid battery drain in cold temperatures. My options are to replace the battery or upgrade to a new handset, probably a newer iPhone se model. Has anyone upgraded their iPhone battery and had a positive outcome from this?
