Default Droid maxx battery problem

hey there!
the title is right! i have a serious problem with my maxx's battery.
i searched in xda forum but i couldn't catch any same results. first i should tell u that i'm not living in U.S so I'm not using 4g LTE...
my droid maxx battery is draining really fast. it can't stand more than a single day of normal usage,the same results of the ultra. I'm not using any mobile networks,I'm just using wi-fi for internet connections. but the result on battery monitoring says that the screen is draining battery,which i dont use it really much! in the battery section in setting,screen used about 46%!!! for example i just unlocked the phone for checking it's battery,2 times in just 30 minutes,and each time the screen went on,the battery percentage got down by 1%. I was using a droid maxx HD before,its battery could run for more than 3 days for me on a normal usage! but my maxx barely goes more than a single day. what can i do? change battery? or any changing in software?
i'm on 4.4 android,not rooted.
i should add that it's about 17 hours which i'm on safe mode,in this 13 hours i was sleeping about 9 hours.and when i started on safe mode it had 62% of battery. now it's 42%!!!!!

sorry for bad english,
thanks for helping
