[iMore Question]

Current Percentage: 44%
Usage: 3 Hours, 17 Minutes
Standby: 22 Hours, 36 minutes
(These usage and standby statements are after full charged 100% and unplugged)

Hi guys!

I would like to know ur Opinions and Experiences of Iphone 5S battery usage and standby.
After I have updated to IOS 8.3, it felt like the drain felt a bit quicker than usual (IOS 8.2 or 7) with normal usage. And my Iphone 5S will drop 3% for 6 hour on standby mode, is it normal?

My normal usage TODAY is (ONLY USING WIFI for Browsing Safari and YOUTUBE):
Youtube: 20 minutes
Safari (only read wikipedia): 20 minutes
Music (not online): 20 minutes
Video (not online): 5 minutes
Call: 10 minutes
Games: NEVER PLAY
Apps (Wechat, Whatsapp, Facebook, Instagram ONLY): 10 minutes (without chatting, only browse)

Can I have your Opinion and Experiences Guys ? Is it normal for my CURRENT situation of this Iphone? Lol
Im android users before, 1st time using IOS
