My iphone 6 battery is suddenly dropping from around 45% to 25%. Is it a software issue (ios 9.2.1) or is my battery dying?
No. But I have been using this phone for almost 3 years now.
Alright, in that case, it could be that the battery is reaching the end of its life-span. You can check your battery health by going to Settings > Battery > Battery Health. This option is only available for iPhone models 6 and newer.
