Q: Battery Percentage Bar ???

Yes, that's what it's supposed to do. The indicator is only green when the phone is plugged in.

Honestly, I don't pay that much attention to anything but the percentage number. There are some minor differences between the iPhone 5S and the 5C and I have a 5S. If the phone is still using battery in the normal way, I wouldn't worry about it.

Try a Reset by holding down the Sleep (Power) Button and the Home Button at the same time for about 20-seconds.  When the Apple Logo appears you can let go of both Buttons and just wait until the iPhone returns to your Lock-Screen.  Hopefully your Green then White with used portion Black will be back to normal. 

Not sure this applies to the 5c, but on my 4S the battery status icon also changes color based on the background of the app you're in.

For example, if I'm in the Messages app, which has a white background, the status icon is black (assuming my phone is not plugged in).

When I exit to the home screen, the icon switches to white as my wallpaper is a darker image.

Perhaps you are seeing the same?

Hi guys after i updated my 5c battery is discharging too fast. I tried everything but it does not work. Is there a way to get back to older ios like 7.0.2

No, Apple do not support downgrading.

Hi Lugi, thanks for your reply. I just wanted clarify here as some sites are claiming the downgrading is possible. Anyway I was wondering if I restote via Itunes will the fast discharging of battery improve?

Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues

Downgrading "may" be "technically" possible through jailbreaking, which WILL VOID any and ALL warranty you may have and support from Apple and these forums ( Please read the ENTIRE article I linked to ).

You also put yourself at significant risk of turning your iPhone into a very expensive paperweight.

I have found two articles online that may help with the battery drainage issue until Apple releases an update that fixes the issue: 1.)http://www.macobserver.com/tmo/article/how-to-manage-and-control-cellular-data-u sage-on-your-iphone.

2.) http://www.macobserver.com/tmo/article/how-to-improve-iphone-battery-life-in-ios -711?utm_campaign=tmo_waylf.

I can not say how good or valid the information in these links may be as I don't have an iPhone.
