Battery life is the most important feature of any modern mobile phone, it’s what powers it up for the day ahead. Most things nowadays have been integrated into our mobile phones, making them irreplaceable. Our mobile phone acts as a way of payment, communication and even an alarm to make sure we’re up every morning. So when this fails us, everything becomes very limited which is why we’ve put together a list of mobile phones with the best battery life in 2025. Find out which phones, ranging from iPhone to Xiaomi, have the largest battery that will get you through the day.
When it comes to battery life, you should focus on looking at the capacity of the battery; the ‘mAh’ which is a unit of measurement used to describe how much power your phone’s battery can store and release over time. You should always check for the highest mAh or aim for 4000 mAh at a minimum as the bigger the capacity of the battery the longer it can stay without the need to recharge. It’s also worth looking at the specifications on fast charging, battery consumption on standby as well as software features such as ‘low battery mode’ that are designed to improve battery life. Here are our top picks for the latest mobile phones with the best battery life in 2025:
We are starting off strong with our first choice and although it may not be a popular pick in a generation of iPhone, Samsung and Pixel users, we think that Red Magic 10 Pro deserves the top spot in our 2025 lineup. The battery capacity is super impressive, offering 7050 mAh and 52 hours of power on standby which is much more than you can get with a regular flagship. Which, apart from the Energizer Hard Case P28K that packs a mammoth 28000 mAh battery, the Red Magic 10 Pro is an impressive device that has a battery that won’t weigh down your hand too much! The Red Magic 10 Pro is the perfect phone for gamers, streamers and those who enjoy travelling and do not have enough time to sit and charge their phone every few hours.
The Red Magic 10 Pro also supports fast charging of up to 100W and comes with a 100W GaN quick charger in the box. This means that your device will be able to go from 0-100% charge in under 35 minutes which is incredible. Not to mention that they have gone the extra mile and included a clear phone case too as a nice added touch. All of these features solidified its position as number 1 in our top 5 mobile phones with the best battery life and we think you’ll probably agree especially at a starting price of £579.
The Motorola Edge Plus 2023 stood out to us due its impressive battery life and affordable price tag of around £400. It packs a hefty 5100 mAh battery, allowing it to consistently deliver a reliably long battery life on a single charge. Even from moderate use, it can last 40 hours on a single charge even whilst undertaking tasks such as browsing the internet, texting, calls and video streaming. You may even get away with lasting a full day whilst gaming excessively without having to recharge which is why the Motorola Edge Plus 2023 is our second choice and a leading contender for the mobile phone with the best battery life. Imagine how long it can last with these tips to improve the battery lifespan! Although the Motorola Edge Plus 2023 does not include the latest Snapdragon processor, the Snapdragon 8 Gen 2 is still powerful and ensures battery optimisations do not sacrifice performance over having a good battery life.
In third position, we have the Google Pixel 9 Pro XL with a large 5060 mAh battery capacity that delivers more than 24 hours of battery life and up to 100 hours of battery when using the Extreme Battery Saver feature. We think that this information alone is enough to tempt you to purchase this device, especially if you rely on your mobile phone’s battery life more than the average person. This device supports wireless charging of up to 45W which means that you don’t have to worry about being attached to an annoying cable when on the go. It is also equipped with the Google Tensor G4 which is bound to further boost the battery power.
Next up we have the Samsung Galaxy S25 Ultra which is a great phone all round and it certainly passed the battery life test. It’s part of the latest Galaxy S25 series and the only model to have reached the 5000 mAh battery capacity with the S25+ coming in at 4900 mAh and the S25 at 4000 mAh. Samsung claim that the Galaxy S25 Ultra should last around 31 hours when watching videos which is more than the S24 Ultra which had 30 hours. Of course, it's best to take this with a pinch of salt when comparing this to a realistic day in the life of mobile phone usage. If you use your phone for a 2-hour commute, both ways, then you'll likely drain your battery much quicker than someone who has less screen time during the day.
Samsung also offers manual controls over display refresh rate meaning that it can be set to up to 60Hz, making it less taxing on the battery.However, Samsung hasn’t improved the battery capacity since the S23 Ultra and remained at 5000 mAh. This means the latest Snapdragon 8 Elite has done a great job in keeping the S25 Ultra powered up and supported throughout the day plus it also has the same fast 45W wired charging speed as the S24 Ultra.
The iPhone 16 Pro Max is on our list but not one of our top contenders, mainly due to the fact that whilst the exact mAh battery capacity is not officially published by Apple, it is likely that it comes in at around 4685 mAh. With moderate use, the iPhone 16 Pro Max should last you around 33 hours when using video playback which is an impressive figure considering that it is the mobile phone with the smallest battery capacity on our list. With fast-charging capabilities, you will be able to get a 50% charge in 30 minutes using a 30W adapter. Apple's A18 Pro chip provides fantastic power management which is exactly what the iPhone 16 Pro Max includes and makes up for the smaller battery size.
Like most smartphones on the market, the iPhone 16 Pro Max is equipped with battery optimising features which is certainly going to help with reducing wear and tear of your battery cell over time. The phone will learn your charging and usage habits so that when you plug your phone in, it will schedule when to stop charging, delaying a full charge until you need it, so that the charge cycles do not age the battery too quickly. You can also make use of the low power mode setting if your battery is running low and need it to last a little longer until you can charge it.
Of course we can't ignore that there has been many conspiracy theories against Apple and their iPhone batteries over the years, most notable in December 2017 where Apple finally admitted that it had intentionally been slowing down older iPhone models because of battery issues. It was later found that this mammoth money making company had in fact been deliberately slowing down the iPhone 6 and 7 series as well as the popular SE models. They have since addressed the issue and it seems that their newer iPhone models have not only improved in battery size, but also are lasting much longer than its predecessors which is why we've included the iPhone 16 in this lineup.
So there you have it, those are our 2025 top 5 mobile phones with long battery life. When purchasing your next device, you should make note of just a few features such as the mAh, battery optimisation options and which processor it includes. By focusing on this, it will ensure that you find the mobile phone best suited to your battery life needs.
Unfortunately, the digital age has made cheating harder to spot, but it doesn’t make it any less real. Over the past decade, the concept of what constitutes “cheating” has expanded to include a variety of behaviours that might not have been considered cheating a generation ago.
The Galaxy S25 marks the latest addition to Samsung’s flagship portfolio. In the lead-up to the launch of the S25, we analysed on-site trade-in prices of the past four generations of Galaxy S series (S21, S22, S23, and S24) to gain insights into how well these models retained their value during their first year on the market and what the first 12 months for the S25 might look like.
As each year progresses, it seems as though AI and GenAI is being woven into our society creating more and more innovative tech advancements. From generated text, images, videos and even technology that works to detect cancer, you can expect AI to be able to create all types of content and task completion which is only to be improved on in 2025.
