who is your phone carrier provider?
ORANGE / CELLCOM / PELEPHONE / HOT MOBILE? Or maybe one of the virtual network carrier?
 
I would usually charge my iPhone 5 at night before I went to bed, then set it on the nightstand for 8 hours. When I woke up in the morning, I usually had 98-100% battery remaining. If a battery is dropping 10% in 8 hours just sitting there asleep doing nothing, I'd say that's not satisfactory unless you're in an area with bad cell coverage and it's fighting to keep a signal or something.

I've also found though that when you fully charge the battery, it might stay at 100% longer in some instances than others. Sometimes when I unplug the phone after a long charge, it will go down to 99% almost immediately, while other times it will stay at 100% for a much longer time.

Your phone usually isn't just sitting there doing nothing. There are all sorts of background tasks now, which you can customize in your settings.

I realize that. No phone that is turned on and connected to the network (or wi-fi) is probably ever actually "doing nothing", so maybe my phrasing it that way was oversimplifying. What I was getting at is that the screen isn't on (which is probably the biggest battery eater) and activity is minimal compared to when it's being actively used during the day for phone calls, texts, web browsing, gaming, etc.

My point was just that it would seem unusual, at least to me, to lose 10% battery while sitting on the nightstand overnight. I could maybe see it happening if somebody had a ton of background tasks running, but if I ever lost 10% overnight I'd be digging into settings and seeing what's causing it because I've never seen it before on any of my iPhones and I wouldn't consider it normal.
 
very bad battery life on a new iPhone 5S

I would uninstall Facebook for a week and see how your battery life changes. Facebook, in my opinion is a huge battery eater.
 
Not really, as the phone just being sat on a desk for 8+ hours would drain the battery by at least 10%.
My phone sitting idle at night for 7 to 8 hours drains like 1%. I would be concerned if it drained 10% during even a whole day of standby.

On my 5s, I would usually get 9-10 hours of usage plus a couple of days worth of standby on a full charge. My usage is no doubt lighter than many of the posters here, but I've also found that signal strength matters a lot. When it's weak, the phone burns a lot of power looking for a strong signal.

what ios your iPhone is running, and also by saying light use, what exactly do you do on your iPhone ? if i can ask..
because 9-10 of usage is very good.

The numbers I quoted were for my 5s running the latest version of iOS8. I got a 6 last month, and I get more or less the same results for the same usage.

My typical use includes:
- checking responding to emails fairly frequently (but push notifications turned off)
- Facebook (usually one of my biggest battery drainers)
- twitter
- some texting.
- some brief phone calls (who actually uses their phone to talk anymore. Lol)
- music

More occasional use includes YouTube and Google maps navigation, but the latter especially puts a dent in battery life. Brightness is always set to auto, which I find keeps the display fairly dim but usable. Background app refresh turned off.
