Battery-saving tips for your iPhone

Learn how to charge your smartphone smarter. Didn’t think this was possible? Think again. You may have thought charging your phone was pretty simple: You plug in your phone and you let it get back to its former glory. Nope. Here are our battery-saving tips for iPhones…

Don’t expose your phone to heat

Extreme temperatures, whether it is cold or heat, are not good for your smartphone. One of these is sunlight, whether it’s direct or from sitting in a car. Exposure to extreme heat and direct sunlight are disasters for your smartphone, which all seems to make sense when you think about what your phone is made of. The first thing that happens is that your battery life will start to drain faster. Exposing the battery to excessive heat can damage the battery performance permanently, especially if the battery is charging or even 100% full and exposed to direct sunlight or heat.

You don’t have to wait until it’s fully drained to recharge

Lots of people make this mistake: You keep using their phones until it practically begs to be charged when it hits 10 to 15 percent or even just shuts down because there’s no more juice in it. What users should remember is that their smartphones use Li-ion batteries and those do NOT need to be drained then charged in full. In fact, Battery University says that following this practice only shortens the lifespan of Li-ion batteries because it adds stress.
Here’s our top tip for a quick charge: If you’re in a hurry and need to get more juice into your battery faster, turn your phone onto Flight Mode, turn the screen off and let it charge. When your phone isn’t connected to any networks or doing any battery-intensive tasks like using the screen, it charges much faster!

Leaving your phone on charge overnight

This one has been up for debate in smartphone circles for years. People at Battery University in the US say that smartphone users who plug in their devices before they sleep, then pull the plug when they wake up many hours after, are actually damaging their battery by doing this. The theory is that the temperature rises when the battery is overcharged and shortens the battery life due to stress. On the other hand, some say this is not true. PC Magazine spoke to smartphone engineers who said that devices these days are “smart” enough to know not to overload. “Extra protection chips inside make sure that can’t happen in a tablet or smartphone or even a laptop. Once the internal Lithium-ion battery hits 100 percent of its capacity, charging stops,” says PC Magazine.

So, if you want to charge overnight: Make sure you’re charging your phone in a well ventilated area so that it doesn’t overheat while charging. Also, make sure your phone is at least 1 metre away or, even better, on the other side of the room. Why? Well, radiation exposure has not been completely disproven in our view and we would rather you exercise caution. It doesn’t hurt, right? This way, you’ll get a better balance.

Find out which apps are sucking your battery life

Luckily, this isn’t as hard as it may sound. Every smartphone, no matter which manufacturer you’ve chosen, will give you some kind of summary in your battery settings that shows what is using up battery life with a percentage. Close the apps that are draining your phone when you’re not using them and consider creating a time limit for how much you use it on a daily basis.

How to find out which apps are draining your battery:
– Visit your Settings
– Select Battery
– Scroll down to see a list of your apps and the percentage of battery use.
– Use this as a gauge to decide which apps you don’t need or can cut down on

Use Low Power Mode or Flight Mode

Believe it or not, this really works. When you batter reaches 20% and then 10%, you have the option of activating Low Power Mode. However, you can activate this feature even when your phone is at 70% or 80%. This dramatically helps your charge last longer.


Which features does Low Power Mode disable? Let’s look…
– Your emails will not automatically receive
– Background app refresh is paused
– Automatic downloads are paused
– Some visual effects will be temporarily paused
– Auto-lock defaults to 30 seconds
– iCloud photos temporarily paused

How to activate Low Power Mode:
– Visit your Settings
– Select Battery
– Toggle Activate Low Power Mode
– Or, alternatively, you can swipe up/down your Control Centre and toggle it on from your home screen

Turn down your brightness and haptics

Believe it or not, that little sound your phone makes when you get a message or when you’re typing a message can drain your battery. The same goes for anything that vibrates. Another thing – your screen’s brightness. You don’t need it to be on 100% to be able to see! Turn it way down, especially when you’re streaming from your phone.

How to turn down your haptics:
– Go to Settings
– Select Sounds & Haptics
– Toggle off Vibrate on Ring and Silent
– Then, use the slider to turn down the volume

How to turn down your brightness:
– Visit your Settings
– Select Display & Brightness
– Toggle off True Tone (this feature gives you a more lifelike look in terms of colour and does draw juice from your battery)
– Then, use the slider to turn down the brightness

Stream on a lower resolution

This not only chows your battery but also your data. Whether it’s YouTube, Netflix, Facebook, DsTV or Showmax, turn down that streaming resolution from HD to about 700 mps or anything under 1 GB. It will certainly make your battery and data last longer!

Disable location services

When you get your phone straight out of the box, your location settings are made to be able to find and track you 24 hours a day, 7 days a week. Well, this is unless you manually change it.
Do you need all your apps to be permanently locating you?
Definitely not. You might want to keep your location services on for apps like Facebook, Instagram, Google Maps and Weather for sharing your location in social media posts or up-to-date info about the weather in your city, but not all apps need to constantly know your location. For example, your Notes app, Voice Memos, Calculator, iMovie, Facebook Messenger and many more don’t need it. Your iPhone will give you three options in terms of curating your location services: You can choose “Never”, which means the app will never be able to use your location, then there’s “While Using” which means the app will only access your location when you’re using the app. Then, lastly, there’s “Always On” which always has access to your location.

How to choose which apps use your location:
– Go to Settings
– Go into Privacy
– Toggle ON for Location Services
– Then, toggle OFF which apps you want to switch off location services for or choose to leave it on while using the app only.

Block ads from reaching you

For some time now, Google has been making money off of using your location to forward ads for shops, services, restaurants and more each time it uses your location. For example, Google will pick up that you are in a popular mall in Cape Town and will divert ads to your feed based on that location. This means that your phone is constantly sending information to update and maintain your location – and this takes up a lot of power. You can choose to use location services only while using that particular app, and not all of the time.


How to stop ads from using your location to reach you:
– Visit your Settings
– Select Mobile Data
– Scroll, then select System Services
– Toggle off Location-based alerts, Apple ads and suggestions

Turn off background auto-refresh

When you get your phone, whether it is new or used, the settings have all been restored to factory mode. This means that all of your apps have been set to automatically refresh and update as soon as there is one – and that could be every day depending on how many apps you have (we have a lot).

How to turn off your background app-refresh:
– Visit your Settings
– Select General
– Toggle your auto-refresh to manual
– Then, select the apps you want the refresh to be manual or automatic

Use Flight Mode for speedy charging

Flight Mode is another awesome solution for your battery woes. If you aren’t using your phone at all for a period of time (say when you’re watching a movie or in a meeting), put your phone on Flight Mode. You won’t be connected to any networks or WiFi connections and therefore can’t receive battery-draining content from messaging platforms, social media, email or app updates.

Not helping? Your battery might need to be replaced, then. Here’s how to check the health of it:
– Visit your Settings
– Select Battery, then Battery Health
– Here, you will see a percentage of your battery health relative to its condition when it was brand new. The higher the number, the healthier your battery. For example, 100% is the highest number and signifies a healthy battery.
– In the first frame below, you will see on your phone a summary of the last 24 hours and alternatively, 10 days. It will show you a list of your apps with percentages showing how much of you battery juice has gone to each app.
