Why is my Passport's battery draining so quickly?

I have had my blackberry Passport for almost a year now (since the day it became available) i haven't had much problems with the battery it sometimes lasted for 48 hours almost.

Recently I have started having problems with the battery life. I was so frustrated that I did a SECURITY WIPE twice, DELETED all Android apps, ERASED and FORMATED the media card. I ahve also disallowed all the apps to run in the background or when minimised and have my display brightness set to the lowest! I do not know what else can be done.

I have been charging the phone with the official charger which came with it, and sometimes the one which came with the Q10!

Please help as I was very proud of my blackberry lasting more then a day with full load.

I disconnected my phone from the charder at around 10am. Its is now 5.30pm and my phone is already on 37%. In my device monitor these are the results:

Display - 21%
System - 16%
Standby - 4.5%

Is the display and system percentages normal?

Thank you very much in advance!!!

first go into your picture app swipe down from the top and in the settings turn stories off, also after doing a wipe it might take a few days to settle back down,
