iPhone 6 battery dropping rapidly?

[boovish]

For the past few days my phone's battery has been around 60-55% by the time I plug it it, when normally it's at 88-95%. I just rebooted it, because I thought maybe it just needed a reboot to fix it, but instead the level dropped 10% to 47%. I'm running the latest iOS 9 beta, has anyone else been having issues like this

Update: I just plugged it in, and it jumped to 50%

Just do a reset. Press on/off and home button together for 5-10 sec till the Apple logo reappears, this just resets your battery and should solve your problem
