Smartphones are great dates: they look good and they are patient with you while you take photos, reply to emails, browse the internet and respond to messages. The flaw almost all of them have however, is they don't have the stamina to last all day and night.

The chances of it making it through from breakfast to dinner, after dinner drinks and your Uber or train ride home are pretty minimal, no matter what device you have.

Here are 13 battery tips to squeeze as much life out of your iPhone as possible.

Sometimes you need your display to be nice and bright, but most of the time it's not necessary, especially indoors.

Slide up from the bottom of your home screen and toggle the screen brightness to as low as you can go. You can always ramp it back up if you need to see something specifically and then flick it back down.

You don't need every single app you've downloaded on your iPhone to be refreshing in the background so turn off the ones you don't need.

Unfortunately, this means going into each app individually to check if background refresh is on, but it will be worth it if you have your iPhone to order your Uber at the end of the night. Head into Settings and scroll down to see all the apps on your device.

Most of us turn hit the power button to check for notifications or the time, but it's easy to forget to hit the power button again to turn the display back off.

Making sure Auto-Lock is set to the shortest possible time, which is 30 seconds, will ensure your display isn't using power for longer than necessary.

As we said above, many of us have a habit of constantly turning our screens on even when we know we haven't had a message and we looked at the time two minutes ago.

Try and avoid turning your display on unnecessarily as much as you can. It sucks a lot of power, which you could use for more important things.

Searching for signal is one of the biggest power munchers so if you are in an area that has weak or no signal, consider turning airplane mode on or turning mobile data off.

Airplane mode is not ideal as it means you'll get no calls, messages or anything else coming through but it will save your battery and it can be done easily, swiping up from the bottom of the home screen.

Turning mobile data off will mean your iPhone will still receive calls and texts but it won't be constantly searching for 3G. To do this, head to Settings > Mobile Data and toggle Mobile Data off.

Tracking location means your iPhone is constantly using Wi-Fi networks, Bluetooth and built-in GPS to pinpoint where you are, which obviously will use battery power.

If you aren't using a specific app that requires your location data to get you somewhere then turn it off.

Vibration alerts are useful, especially if your iPhone is on silent, but they require the use of the motor and that motor needs juice from the battery.

To do this, head to Settings > Sounds and toggle Vibrate on Ring and Vibrate on Silent off.

You probably don't need to be notified for absolutely everything that is going on. Yes, it's useful to get WhatsApp or Message notifications but do you really need to know when someone has commented on your new Facebook profile picture? Probably not.

Limiting the number of notifications you receive will help your battery life and maybe even your sanity. Like background app refresh, you have to go through each app individually. Head to Settings > Notifications and then start filtering through your apps.

It's useful to get emails as they are sent, but just because you get them straight away doesn't mean you have time to read them straight away.

Changing your email settings so you get them manually instead of your iPhone fetching them will help save your battery life. If you don't like the idea of entirely manual, change the fetch schedule to a longer duration such as hourly instead of every 15 minutes for example. To do this, go to Settings > Mail, Contacts, Calendars > Fetch New Data.

Siri is always listening. That means Siri is always using your battery. You can turn the Hey Siri feature off easily enough so it's worth doing if you're trying to save some juice.

To do this, go to Settings > General > Siri > Allow "Hey Siri" and toggle it off.

There are some apps that eat more battery than you would think. It's worth checking which apps you are using that are impacting your battery life the most so you are aware.

Head to Settings > Battery > Battery Usage. You can choose the last seven days or the last 24 hours. It's worth checking both to see if you can see a pattern or figure out which apps to especially avoid.

We mentioned turning on airplane mode or mobile data off when you have weak or no signal, but it's also worth turning Bluetooth off separately.

You might not always be in a position whereby airplane mode is convenient but turning off Bluetooth on its own will still save battery. Swipe up from the top and toggle Bluetooth off from here.

If all else fails, Apple has a Low Power Mode that will reduce power consumption as much as possible. This mode will turn off background app refresh, Hey Siri, Mail fetch, automatic downloads and reduce visual effects.

To turn Low Power Mode on, head to Settings > Battery and toggle it on.
