Was it getting really good battery life the moment Apple replaced it? Not sure about that app, but cycle counts should be for each individual battery and not the lifetime of the phone. Put that battery Apple installed back in and take it to Apple and have them check the cycle counts. If it really is 1258 cycles, that's literally impossible if you bought it back in Oct of 2015 (if it really is a new battery). Some other explanation I can think of is that you're using some really cheap charger or the conditions in your area is terrible for the phone, like super cold or super hot.
