Iphone 5s battery drain

[Magickiller9]

I left my iPhone overnight. It drain 85% with 22mins usage and 11hour standby.

If i bring it out, it could't even last 2-3hours of normal usage before dying on me.

Did a full factory reset, totally nothing on. Leave it standby, it drain 6% within an hour.


Contacted Apple Singapore, they told me there's nothing wrong with the battery...

What to do? =/.

I think it is like any smartphone, battery life drops after a certain amount of usage.
I'm using iPhone 5, similar problem. May change battery soon.

Can try dim screen brightness, disable 4G, disable wifi when not in use, etc, to save on usage

One last thing. When's I was in HongKong or Malaysia, The battery drops much less when on standby
