iPhone 5S battery drain problem. Too hungry?

[STiTUNED]

After using the 5S for around a week, must said quite impressive than the 4S which I used perviously.

But I was shocked after I tested out the battery.

Basically, I off everytime including data and left the phone for almost a day with some SMS and short call. The battery dropped to 87% the next day but after around 6 hours or so, the battery suddenly dropped to 45%.

Any guys here can advice on this and anyone also have such similar problem?

Btw also felt abit laggy when scrolling between homescreen, opening/closing of apps. Is it normal too?

The battery drains pretty fast.
using wifi at home, fully charged, went out just on my 3G then my battery in less than 10 mins directly dropped 1%. l I think because iphone 5s, the cellular data directly using 3G, unlike 4s last time when u on the cellular data is on Gprs

I dun find it lag eh, perhaps u din kill those open apps?

My 5s has similar problems while on standby. off data and on dnd mode but woke up to ~20% battery drain.

Already switch off those location services and stuffs.
Any guys got solutions for this?

Try restoring and setting it up as a new phone and monitor. If it still doesn't work u should bring down to your telco's designated apple csc.
