19 Proven Tricks to Increase Your Phone's Battery Life

19 Proven Tricks to Increase Your Phone's Battery Life

Smartphones can do just about anything these days, from organising your life with clever apps to taking amazing high-quality photographs and videos. But have you noticed your battery power can't quite keep up? We have! So we've researched and found 19 secret ways to make your phone battery last longer than ever. 

1. Keep your phone out of sunlight

Look after it!

According to Mobile Choice Magazine, Lithium-ion phone batteries work best when kept at slightly below room temperature. Make sure your phone isn't heating up by keeping it out of direct sunlight or anywhere that's excessively warm - like in your car on a hot Summer's day.

Your phone battery will love you for it!

2. Turn the brightness level down

Go into your settings and turn the brightness level down. The brighter your screen, the harder your phone battery will have to work to keep it lit. Turning the brightness down really can make a huge difference to your battery life and it's also gentler on your eyes.

iPhones and some Android devices may have an 'Auto-Brightness' mode that will adjust the brightness of your screen based on the light around it. By enabling this function you will save some battery life, for example when your screen needs less power in well-lit areas, but if you're serious about saving your battery it's best to turn it off and set the brightness to continually low. You can always make it brighter at any point if needed.

3. Set your phone to automatic lock

For when you forget to click that button.

Most phones will stay lit for a specified amount of time after you've used it so don't leave your screen to work unnecessarily. Change the settings on your phone so it either times out or locks itself after 30 seconds. Look for an option called 'screen timeout' on Android devices and 'Auto-lock' on iPhones - you can tweak the times on both to suit your needs.

4. Switch off the vibrate function

Your phone battery uses a lot of power to physically move your phone when it vibrates, especially if it vibrates on notifications as well as messages and phone calls. Conserve your battery by switching off the vibrate function completely.

5. Close all those open apps

open apps
Swipe them away!

The beauty of modern smartphones is that they let you multi-task with your apps and functions. Switching from Facebook to an internet page or WhatsApp conversation within microseconds may be hugely convenient, but being able to open so many things at once means we often forget to close them down. You might clean the outside of your phone, so why not do some housekeeping inside it too? 

If you don't close them, your apps will still be 'open' even if you're not using them. This means your phone will be working hard secretly powering all your open apps without you even realising it. Make sure you remember to close them down every time you stop using one and your phone battery will improve considerably.

On iPhone, you can double tap the home button and it will show you what apps are running. Kill them off by swiping upwards and you can even close several at a time using a finger on each app.


While you want to close down un-used apps, you don't want to be continually opening and closing apps as this will also make your phone work harder. If you know you will be using the same app - like WhatsApp messenger - for a while then it's best to keep it open.

6. Choose a dark background

Always remember: phones use up more battery lighting up white and light colours and LESS battery displaying black or dark colours. By selecting a dark background image or screensaver, your phone will save precious battery life.

Never use dynamic - that's animated to you and me - screensavers either. They may look fancy but they're a big waste of power.

7. Switch the volume down

You'd be surprised by how much battery this can save!

Just turning the volume down a notch can help conserve your phone battery, especially if you're receiving a lot of phone calls during the day.

You can also change the settings on your phone so you don't have any sound alerts for messages or notifications.

8. Disable screen alerts

You may have switched off the sound for notifications but you can go one step further and switch off screen notifications, too.

Your screen wakes up every time you receive a notification, meaning it switches the screen on and stays lit for a certain amount of time. This could be happening frequently throughout the day without you even realising.

Go into your settings and switch off these alerts for anything that isn't essential.

9. Remember: turn off your GPS & Bluetooth

Does anyone even use Bluetooth anymore?

These two may be hugely useful but they're also power-hungry features that will burn through your phone's battery. Whenever you use either, always make sure you switch them off afterward.

If you want to use maps when you're out and about, you could screenshot the map and save it as an image. This will take up far less battery and your phone will love you for it!

10. Turn off social media notifications

Make sure you switch off unnecessary notifications from social media sites and other non-essential apps to help your battery last longer.

If you can live without being immediately notified you've been tagged in a photo then you can save a LOT of battery power throughout the day.

11. Disconnect from the Wi-Fi

It won't hurt to disconnect.

It's easy to let your Wi-Fi run in the background, especially when you're connected to your home or work network. You may think you're saving precious mobile data by doing this, but if you're not actually using it for prolonged periods of time then you're best switching it off.

It's also worth disconnecting the Wi-Fi as soon as you leave your Wi-Fi hotspot because while this aerial is still connected, your phone will be frantically working hard searching for other networks to connect to. Remember to disconnect your Wi-Fi when you're on the move and give your poor phone a rest! It could even encourage you to have a digital detox

12. Say goodbye to voice controls

Voice controls may be useful and fun, but it will also suck the life out of your phone battery. Even when you accidentally activate it, your phone will use up a lot of battery power just for that one mistake.

If you don't need Siri or S Voice then make sure you disable it in your settings.

13. Say no to 4G when you're running low...

It'll also save your data!

Unless you really need a faster connection, switching off the 4G on your phone will help double your remaining battery life. As soon as you see that low battery indicator, switch it off!

14. ...then switch off 3G when you're in the red

Battery power in the red danger zone? Prevent it from draining completely by immediately switching off your 3G function: your mobile data. You won't be able to use your internet based apps but don't worry you'll still be able to make phone calls and send and receive text messages.

15. Opt out of automatic app updates

Be sure to update them when you're plugged into a power supply again!

If you're using an iPhone with iOS7, it will automatically update all your apps whenever there is a new version available - this can be surprisingly often!

While it may be convenient, it will also soak up your phone battery like there's no tomorrow. Only update your apps when you need to by going into:

  1. Settings
  2. iTunes & App Store
  3. Automatic Downloads
  4. Updates
  5. Move slider to Off/white

16. Swap Google for Black

If you use your smartphone to search and browse the internet, it's well worth switching from Google to Blackl. It's an energy-saving search engine, powered by Google, that features a black background instead of the iconic white. As we've learnt, phones use less power to display dark colours so you'll save a lot of battery if you use this search engine on your phone.

17. Activate flight mode

It's not just for when you're jetting off!

Flight mode is a setting available on most smartphones and electronic devices. When activated, it suspends the device's signal transmitting functions. When you don't need to use your phone get in the habit of enabling this function. Your phone saves a huge amount of power when in this mode.

18. Turn off background app updates

Some apps on iPhone may refresh in the background, updating themselves for when you next use them. This may be useful for when you want up to date information but you can stop this from happening (and burning your battery power) by going into your settings and switching off 'Background App Refresh'.

19. Forgo the flash photography

Flash photography

doesn't look very good anyway!

Flashes on smartphones are so powerful these days they also double up as a torch! While they may help brighten up a dark photo opportunity, they also consume a lot of phone juice so avoid using the flash unless you really need it. There are lots of clever photo editing apps that will lighten up any dark photos you may take.

  5. Author Lesley on February 2, 2016 at 6:39 am

    Much too technological for me - but as I only have a 7 year old Nokia Classic phone it doesn't matter. Good tips for people who have a smartphone - and know how to use them - though!

    Hi, I have a computer. Do you have any ways for them? I tried everything on my iPhone but nothing worked. Do you have better ones?

    1. Author Joanne A on August 16, 2018 at 5:15 pm

      Hello Amanda, Have you tried clearing your files onto external hard drives or cloud storage? This will keep them safe but won't bog down your devices.

    Great, thanks for sharing information about how mobile battery can be kept healthy. You have really listed nice points to take care of the mobile battery life. From my side, I would recommend not to use animated wallpapers which might eat not just the battery but also the processor speed. I would also suggest not to drain the battery to 0%. Everyone should apply charger when battery get down to 5 or 10%. Anyways, very nice article. Couple of points which I was not aware of are mentioned in your post. Keep sharing and good luck.

    1. Author Stephanie C on November 14, 2018 at 2:19 pm

      Those are some great ideas! Thanks, Akshata.

  12. Author Lucy Power on February 19, 2019 at 11:13 am

    Some of these tips are also useful for saving the battery on a tablet so I will try these and see if the battery will last longer.

    1. Author Joanne A on February 19, 2019 at 12:13 pm

      They certainly will work for your tablet, Lucy!

  13. Author zee beach on February 28, 2019 at 1:48 am

    Other easy ways to save battery life: Turn off your phone when you don't want to be disturbed by calls or texts. Don't worry, you actually can have a life without having your phone attached to you 24/7. If it does worry you then you probably need to seek professional help.

    1. Author Joanne A on February 28, 2019 at 10:52 am

      Great advice, Zee! We all need to unplug a little more.

  14. Author alison willis on June 24, 2019 at 8:16 am

    Good ideas for all of us, but also important to remember that excessive battery use - and then charging- is not good for the planet. Electricity causes CO2 production unless it is renewable, which only about 20% is in the UK. So do it for the planet!

    1. Author Joanne A on July 1, 2019 at 4:31 pm

      Yes - reducing battery use is a good step to take for the planet too! Thanks for pointing that out, Alison.

  15. Author Martin Ekert on June 24, 2019 at 8:01 pm

    Nice article, but unfortunately there’s a couple of your tips that are very wrong. First one is the “Turn on auto lock” tip. This is actually a bad idea... because if you are using your phone and it locks, it uses a lot of power to keep re-unlocking your phone to keep using it. The other one is the “Close background Apps” tip. This is also a bad idea, as it has been shown that Apps in the background don’t actually affect the battery much at all... and it needs a lot more power to open up the Apps from scratch than if they were sat in the background. A comment from above recommends turning your phone off completely...this is also a very bad idea, because restarting your phone uses so much power and therefore drains the battery quicker. One good tip is to use “Low power mode” or even “Aeroplane mode” when you’re not using your phone. “Aeroplane Mode” is also a great way to charge your phone too, as it enables your phone to charge much quicker.

    1. Author Joanne A on July 1, 2019 at 4:30 pm

      Hi Martin! I'll admit, I use aeroplane mode and low power mode the most. They're certainly the most effective for daily battery conservation.

  16. Author Steph Tickner on June 25, 2019 at 3:07 pm

    Brilliant website, and I have used so many of the tips, especially about power conservation of the mobile phone, various household helps too. Also, have taken advantage of the links, and have similarly benefited. Keep up the good work.

    1. Author Joanne A on July 1, 2019 at 4:21 pm

      We're very glad to hear that, Steph!

  17. Author Donatello46 on May 27, 2020 at 9:14 am

    Here's a revolutionary idea to conserve your battery, only have your phone switched on when you need to use it, i.e. to make a call or when you're expecting a call, it also helps in filtering out nuisance calls, scams etc. and if you miss a call (that you weren't expecting) you can always, periodically, check your "missed calls" list or your voicemail. Just a thought, but it's the way that I use mine, I refuse to be a slave to my mobile phone and certainly don't have it "glued" to my hand (or ear), it's for me to contact others when I need to or for them to contact me by prior arrangement.

    1. Author Joanne A on June 2, 2020 at 11:36 am

      Thanks for the tip!

  18. Author Mandy P on December 21, 2021 at 2:24 pm

    The single most effective way of keeping your phone OR tablet battery healthy is not to charge it to 100%, lithium batteries get hot while charging and they have heat, it's recommended that you charge to about 60% to prevent it heating and damaging the cells. If you do this from new the battery should last and last, I've done this with my latest phone and tablet and so far 2+ years on and my battery health is still as good as the day I bought it. Charge little and often. Leaving a fully charged phone plugged in after reaching 100% too can quickly damage a battery.

    1. Author Joanne A on July 28, 2022 at 10:28 am

      That's a great tip!
