Iphone 5 battery life problems?

There are a lot of ways to extend your battery life. Here are some of it:

Disable the parallax effect

Turn Off Location Services

Prevent Background App Refresh

Fetch data manually

Don't automatically update apps

Auto-Lock iPhone and iPad

Disable notifications

Keep it cool (yep that's right!)

Turn off vibration

This can also help:

Restart/reset your device. If you haven't rebooted in a while, give it a try. There could be a rogue process or something else doing what it shouldn't be doing, and a restart can often fix that.

Power cycle. About once a month, and certainly if you're having problems, you should completely drain your iPhone, iPod touch, or iPad's battery -- drain it until it shuts down on its own -- and then charge it back up to full.

Restore your device as new. The single biggest cause of battery life problems with iOS devices occurs when they are restored from backup and not set up as new devices. Whether it's cruft or corruption, a clean install as a new device -- incredible pain in the butt though it may be -- is usually the best fix for any battery life issues. This is the nuclear option. You will have to set up absolutely everything again, and you will lose all your saved data like game levels, but in most cases your battery life will be better than ever.

Check your cell signal. If you're in an area of weak signal, or at the edge of LTE or 3G support, your iPhone's radio could be screaming away on full power just trying to stay on the network, or switching between connection types, and wasting a lot of power. If you have bad reception, consider a micro-cell at home or at work. If you're at the edge of LTE, turn it off in Settings and stick with 3G until you get to a place with better coverage.

You should also turn off these features:

Siri's raise to speak, push notifications, notification center widgets.

I hope this will help you :)

the iphone does have a decent battery. but smetime batteries can drain over the years. most mobiles are made in china, so the parts are built anything upto 2 yrs before the phone is actually mad, so sometimes these parts malfunction. and batteries can occaisionally paly up. my advice-get a new battery

Drain the battery.

Charge the battery to 100% without disconecting the phone, and after it has reached 100%, leave it conected for 20 more mins.

Do this two consecutive times. It should help.
