Samsung Galaxy Note 5 – 15 hours

This is the fifth edition in the Samsung Note collection and it has a notably better battery life than other Samsung models. This smartphone includes wireless charging which you can take with you when you’re on the go, but it also means that the phone can charge from a dead battery to fully-charged in 120 minutes.

Huawei Ascend Mate 2 – 14:43

Huawei claims that the Ascend Mate 2 battery lasts up to two full days with heavy usage. While tests have found that it doesn’t actually last quite as long, the battery life is still pretty impressive. The smartphone has three different consumption modes: Smart, Endurance and Normal. The different modes adjust to the CPU speed and network usage to enhance your battery life when it’s most needed, ensuring it doesn’t lose life unnecessarily. The battery on this phone can also charge other devices but you’ll need a micro USB or cable.

OnePlus One – 13:16

At 3100mAh, the OnePlus One smartphone battery can last for a substantial amount of time without dying. You can watch videos at 720p of up to 90 minutes long, with maximum brightness and still have 80 per cent of the battery left. Leaving you plenty of time to send emails and texts, play games, make calls and use the phone’s different features.

HTC One M9 – 13 hours

The HTC One M9 has a larger battery than the M8 model meaning the battery life of the more recent version of the smartphone is slightly more impressive. Using your phone normally for texts, calls, emails and photos it should last you the whole day and you should have at least half of the battery left. However if you are planning on using it heavily for the duration of the day, by gaming, navigating or watching high quality videos you can expect it to last around 13 hours.

Google Nexus 6P – 12:25

The Google Nexus 6P takes only 1 hour and 37 minutes to reach 100 per cent battery and can last a little longer than one day with a large amount of use. The battery life depends on the display settings but the adaptive brightness feature will enhance battery life. You can also put this phone in a semi-sleep mode or use the minimal battery drain feature.

Google Nexus 5X – 11:30

The Nexus 5X has a 2,700mAh battery and thanks to the USB-C it has a rapid charging time, meaning that even when your battery is dead it doesn’t take long to charge back up again. Google has included features from the Android Marshmallow including Doze Mode and App Standby, allowing this phone to save power when it needs to.

iPhone 6S Plus – 10 hours

With a 2915mAh battery this iPhone model has an improved battery life compared to other iPhones. With everyday tasks such as listening to music, playing games, messaging and calling, the iPhone 6S battery is able to last all day without needing to be charged.

Samsung Galaxy s5 – 9:42

This smartphone not only has a 2800mAh battery, it also has two power saving modes; Power Saving mode and Ultra Power Saving mode. The battery in general is good and can last around 10 hours depending on what you’re using the phone for but when the battery does start to drop the Power Saving mode will minimise the screen brightness and background data. The Ultra Saving mode allows you to use only six apps and turns the screen black and white.

Motorola Droid Turbo – 9.30

The Motorola Droid Turbo has the largest smartphone battery possible, 3,900mAh, which is impressive. It does have a long battery life and with standard use it is more than capable of lasting all day, however it doesn’t have any power saving modes.

Alcatel One Touch Idol 3 – 9:16

This smartphone has an impressive battery of 2910mAh and with minimal usage it will last you longer than a day. With heavy usage including watching a high quality video, messaging and calling throughout the day, it will last the working day, possibly a little longer. It takes 90 minutes to reach 100 per cent from 25 per cent and it includes a power saving mode.

Tips for extending your smartphone battery life

If you find that your smartphone is losing battery life sooner than it should, it could be due to a number of reasons, all of which can be easily amended. Here are some simple tips you can use to extend your battery life.

Dim the screen brightness

Believe it or not, the screen brightness can affect the length of your battery life dramatically. Turn your brightness level down and avoid using auto-brightness as it’s often too bright anyway. Another thing you can do is to use a darker, plainer background with little detail and no bright colours.

Turn off Bluetooth and Wi-Fi

When you’re not using your Bluetooth or Wi-Fi connection, your smartphone is wasting its battery by trying to search for one. Instead turn them off when you’re not using, or planning to use them.

Don’t leave apps running in the background

It’s an easy mistake to make but leaving apps open in the background uses battery life even if you aren’t actually using the apps. Try to close your apps down as often as possible throughout the day if you aren’t using them. Leaving apps open that you use regularly throughout the day, such as messages and emails is fine.

Power saving modes

This is a really useful feature on smartphones, even when your battery is on as little as 20 per cent, using power saving mode will extend it for a little longer than usual. If you know that you’re not going to be able to use your phone for an amount of time then it’s best to just turn it off.

Turn notifications off

We need to receive notifications for messages, emails, calls and important updates but apps often send us push notifications that we don’t need to receive. This uses up battery life as it will light up the screen, vibrate or make a noise. Spend some time going through your apps and decide which ones you really need or want to receive notifications from, otherwise turn them off.
