Never run out of juice again! Every phone below has guaranteed EPIC battery life!

It’s as if Thor himself swung his giant hammer and demanded ‘More Power… MORE… POWER…’ and the mobile manufacturers answered…

Since everybody already knows that phones with giant-sized batteries are created in dark underground labs, by a bunch of mad scientists who constantly pray to the god of Milliamp Hours (mAh)… I thought it was about time that I share this complete list of… ‘Which smartphones have the best battery life?‘.

Top Tip: Check out our ‘Best Tough & Rugged Smartphones List‘ for more Big Battery Phones with added drop-protection & waterproofing.

You know the feeling, you leave work, reach into your pocket and pull out your phone, excited to catch up on season 3 of Stranger Things and bam! Your stupid phone, with its stupid battery life, only has 8% battery left.

I know your pain, so that’s why I vow that all phones henceforth (in this article at least) will have at least a 5000mAh battery. That means enough battery life to keep you off-grid well into your second and even third day.

Spoiler: There’s a phone on the list that promises 10 days of battery life!

Don’t know your Milliamps from your Millipedes? Or wondering why your smartphone battery gets worse over time? Check out our Smartphone Battery Life FAQ at the end.

Which Smartphones Have The Best Battery Life in 2020? Let’s find out!

Xiaomi Mi Note 10 – 5260mAh



The Xiaomi Mi Note 10 boasts a whopping 5 camera setup with a humongous 108MP main shooter. And when you combine that with the long-lasting 5260mAh battery, you’ll be snapping photos well into the night.

Couple this with a beautiful 6.47″ curved (HDR10) AMOLED display, a gaming-ready Snapdragon 730G plus tons of storage and we have ourselves one of best value phones of 2020.

If you’ve never heard of Xiaomi before, they became famous by copying the designs & build quality of Apple devices before branching off and creating their own designs. The Mi Note 10 carries on this tradition of A-grade build quality looking & feeling way more premium than its £400 price tag.

Another nice bonus is the included accessories. Inside the box, you’ll find a 30W fast charger, a case, and headphones. Thank you very much, Xiaomi!

This is what OnePlus phones used to be before costing an arm & leg…

Xiaomi Mi Note 10 Lite – 5260mAh

With the Xiaomi Mi Note 10 Lite, you lose the high-end 5-camera setup for a more modest quad-camera configuration with the Sony 64MP IMX686 sensor. Also, the selfie cam drops from 32MP to 16MP, which with my ugly mug, is a big pro! Just kidding. You’re unlikely to notice the difference unless you’re a real shutterbug.

This change in the cameras allows Xiaomi to slash the price of the Mi Note 10 Lite passing on the savings to you. But since all the other specifications remain the same, you still get a mid-tier performance powerhouse with a big 5260mAh battery that’ll last you well into day 2.

An almost perfect mid-range phone!

Quick Specs: Android 10 (MIUI 12), Snapdragon 730G, 6GB RAM, 64GBGB Storage, 6.47″ AMOLED 1080 x 2340, HDR10 support, 64MP + 8MP + 2MP + 5MP Quad Cameras, 16MP Selfie Camera

Samsung Galaxy M31

With brands like Xiaomi now dominating the mid-range market, mobile giant Samsung has upped its game in 2020 releasing to the affordable M31 with a huge 6000mAh battery.

With the Samsung Galaxy M31(Amazon), they are offering one of their flagship level Super AMOLED displays at under £250/ $260. What’s not to love!

However, the goodies don’t end there. For all you Instagram-addicts, there’s a 32MP selfie camera plus a decent Samsung quad-camera setup on the rear.

Coming to the performance, it is buttery smooth thanks to Samsung’s inhouse chip, the Exynos 9611 paired with 6GB of RAM. The device can breeze through regular day to day workloads as well as get you through demanding Android games at mid-to-high settings.

Finally, in terms of design, this is the only place where Samsung had to cut some corners by going with a plastic build. However, the plastic body does help to keep the weight down at only 191 grams despite the massive battery, so that’s a big plus.

Grab yourself a Samsung phone that doesn’t die after 5 hours!

Quick Specs Android 10 (OneUI 2.0), Exynos 9611, 6GB RAM, 128GB Storage, 6.4″ 1080 x 2340, 64MP + 8MP + 5MP + 5MP Quad-Cameras, 32MP Selfie Camera

Oukitel K13 Pro

If I had to use one word to describe the Oukitel K13 Pro, it would be “thick”. Admittedly, that isn’t typically how you compliment a smartphone in 2020.

However, when your “phone” packs an 11000mAh battery and doubles as a powerbank to charge/power other devices, then certain conventions can be overlooked.

Now, to mask the 14.5mm thickness, Oukitel has gone with a rugged design which actually ends up adding some personality to the device. However, at 286g weight you’re gonna need some serious pockets to handle this beast!

If the idea of 25 hours screen-on time sounds perfect, then still don’t buy the K13. Let’s be honest, you can carry an 8000mAh power bank around with plus a much better & slimmer device for the same price!

But if you really do want this beast, then the £180/$200 price-tag is reasonable for the low-end specs + huge battery. And thank you Oukitel for adding fast charge!

Motorola G8 Power

I was a huge fan of the G7 Power, and the Motorola G8 Power only builds on its predecessors’ strong points. Yes, the device comes with a 5000mAh battery, qualifying it for this list of smartphones with amazing battery life. However, that’s only half the reason why I have included it on the list.

At first glance, it seems like you are getting an average well-rounded spec sheet that is typical of a £200 smartphone. But then you notice that the device comes with dual stereo speakers with support for Dolby audio, and all of a sudden it’s a bang-for-the-buck media powerhouse.

The audio output from both the speaker grills as well as the headphone jacks is super clean and loud – the best you can get at this price point. And to compliment that, you have an awesome full-HD 6.4″ punch-hole display that makes it an absolute pleasure to use.

Coming to its internals, you have a Snapdragon 665 running the show paired with 4GB of RAM and 64GB of internal storage. That’s more than enough for all your media-centric needs.

The G8 Power Doesn’t disappoint!

Quick Specs: Android 10, Snapdragon 665, 4GB RAM, 64GB Storage, 6.4″ 1080×2300, 16MP + 8MP + 8MP + 2MP Quad-Cameras, 16MP Selfie Camera

Oppo A5 (2020 Version)

The Oppo A5 and the Moto G8 Power are very similar when you take a look at their spec sheets. Both devices have a 5000mAh battery powering a Snapdragon 665 processor, and both have dual stereo speakers with Dolby Audio support.

However, the Oppo A5 is priced significantly cheaper than the G8 Power. In fact, during sales, you can get the A5 with a £60/$70 discount. This also makes the Oppo A5 the most affordable 5000mAh phone which also supports reverse charging.

While OPPO isn’t a mainstream brand in the west yet, it’s been one of the most popular phone makers in Asia for many years producing a range from budget to super-high-end.

The OPPO A5 2020 stays sleek while retaining its big battery!

UmiDigi F2 – 5150mAh

The UmiDigi F2 delivers awesome specs while remaining affordable. What more do you want?

Check out our UMiDigi F2 Full Review.

I wasn’t able to find a single scenario where the F2 underperformed.

For example, are you considering gaming performance? Well, the Helio P70 along with 6GB of RAM made sure I could play PUBG even at the highest settings. In fact, the experience was further enhanced by the FHD+ 6.53” bezel-less display.

The hole-punch display hides the 32MP selfie shooter and the rear quad camera setup is equally excellent featuring high-res, ultrawide and bokeh lenses.

Finally, coming to the battery life on the device, you have a 5150mAh battery that’s complemented by the power-efficient processor and bloat-free stock android. This combination made sure I got 9 hours of screen-on-time, no matter how extensively I used the device.

UMiDigi Never Disappoints!

UmiDigi Power 3 – 6150mAh

The UmiDigi Power 3 is effectively the “Lite” version of the UmiDigi F2 costing 20% less. But at the same time, it also packs 20% more juice battery at 6150mAh.

Now, apart from the bump in battery life, in almost everything else, the Power 3 is either similar to the F2 or offers slightly downgraded specs.

Wondering… What’s the best UMiDigi Phone? Read on!

I really like that you are still getting the FHD+ 6.53” screen for viewing your content. Also, they have kept the same quad-camera module on the back which is also awesome.

However, the front-facing shooter drops to 16MP’s and you’ll also notice a little more noise in photos.

You now get access to 4GB of RAM which is pretty much the standard in 2020 and nothing to complain about. Whereas for the processor, you now have the Helio P60, which is still an awesome and powerful chipset capable of heavy and intensive workloads. You just need to run them at slightly lower graphic settings.

UMiDigi Power – 5150mAh

It seems every mobile manufacturer has their own ‘Power’ branded smartphone now, but what make’s UMiDigi’s version so special is the price tag.

When we’re measuring features vs price, the UMiDigi Power comes out on top as the best all-rounder mid-range phone in this list. The large 6.3″ display is Full HD, it’s also thin at 8.8mm, and it still manages to squeeze in an impressive 5150mAh fast charge battery… letting you ‘Power’ on well into your 2nd day of usage.

And guess what!? It only weighs in at a measly 190g making it one of the most pocket-friendly big battery phones available.

The team at UMiDigi know that we love epic battery life, and that’s why you’ll also find the UMiDigi F1 Play and the beautiful UMiDigi S3 Pro also both rocking a 5000mAh+ battery later on in this list.

Also good news is that this phone is completely bloatware-free. It’s running the latest Android 9 in its stock form. Performance-wise we’re also treated to the energy-efficient Helio P35 processor that’s backed up by 4GB’s of RAM and 64GB’s of storage (expandable up to 256GB’s).

I’ve listed the full tech specs below, but some notable features include NFC, dual-band AC WiFi and a 3.5mm headphone jack.

If you’re on the hunt for a great Android smartphone that ticks all the boxes, you can stop your search right now. But that’d be boring, and there’s plenty more enticing options in this list.

Samsung Galaxy A40s – 5000mAh

Finally, Samsung has realised a big battery smartphone! Hurray! Not to be confused with the original A40, the Samsung ‘A40s’ drops the full HD display but gains a whopping 60% battery life boost.

The display has also grown to 6.4″ but there are fewer pixels to push around, so you’ll be getting at least 50% more screen time. Impressive!

There’s a triple camera setup with dedicated wide-angle snapper similar to the premium Samsung Galaxy range. Why choose Samsung? You know you’re getting epic build quality, a thin (8.5mm) frame and for the size of the battery, it’s super lightweight at 174g.

It’s powered by Samsung’s own Exynos 7904 chip with a massive 6GB’s of RAM and 64GB’s of storage to keep the Android 9 OS running buttery smooth.

Finally, with a battery this big you’ll want some serious fast charging and the A40s doesn’t disappoint with a 15w faster charger included in the box.

Xiaomi Mi Max 3 – 5500mAh

Update: The Mi Max 3 is a little older now, but, I’ve left it on this list as it’s still great-value and is the perfect media-consuming phone.

The Xiaomi Mi Max 3 has healthy 5500mAh battery and a humongous 6.9″ display! If you’ve been looking for a smartphone to binge-watch YouTube, Netflix and Play the occasional game without having to squint! The Mi Max 3 is for you!

The display is Full HD, its super slim at only 8mm and is also featherweight at only 221 grams (size-considered). I’ve reviewed my fair share of 5.5″ smartphones that weigh more than the 6.9″ Mi Max 3.

You get 4GB’s of RAM, 64GB’s storage and Qualcomm Snapdragon performance. The 8-core mobile processor makes light work so social media, video and apps.

Quick Specs: Android 8.1 (MIUI9), Qualcomm Snapdragon 636 1.8GHz CPU, Adreno 509 GPU, 4GB RAM, 64/128GB Storage, 6.9″ 1080×2160, 12MP + 5MP AI6 Rear Camera

Related: Cubot’s Top 5 Smartphones

You can think of the giant 6.8″ Cubot Max 2 as the budget version of the Xiaomi Mi Max 3 above. It lowers the resolution from Full HD to HD, switches from Qualcomm to MediaTek, but, keeps both the humongous (Gorilla Glass 5 protected) display and excellent battery life.

Like most Cubot phones, it also has a true dual-SIM setup. That means you can have two active SIM cards and still add an SD card up to 256GB in size.

The 6.18″ full HD display looks fantastic and scores an impressive pixel density score of 403. Performance-wise, the Snapdragon 636 is a solid mid-range option that’s backed up by 4GB’s of ultra-fast RAM. It’s worth noting that it’s not a gaming powerhouse though, if you’re a big PUBG fan.

Let’s talk battery life. The 5000mAh battery is fitted with Motorola’s Turbopower charging technology which promises 6 hours of use time from a 15-minute charge. The downside? Currently hard to get your hands on one in the west.

Energizer Power Max P18K – 👑 Battery Life King

All hail the new Smartphone Battery Life King! The Energizer Power Max P18K not only has the longest name, but, also rocks the biggest battery to ever make itself inside a phone.

Normally these types of ‘show off’ phones are more of a marketing-stunt than real-life products… but not so with the P18K.

It’s rocking an epic full HD display with minimal borders, dual pop-up selfie cameras, side-facing fingerprint reader, triple rear-cameras and some serious performance power.

Early rumours hint at that the P18K weighing as little as 350g, but my guess it being much closer to 500g. And the thickness is confirmed at a chunky 26mm. With these ridiculous dimensions and weight, you could just as easily super glue a power-bank to the back your phone.

Worth a shot Energizer, but not this time.

UMiDigi F1 Play – 5150mAh

The 2nd of UMiDigi’s phones to make this list is the F1 Play. Everything you could want from a mid-range Android phone is included; NFC, full metal unibody design, great performance and a big 6.3″ full HD display.

What’s the best UMiDigi Smartphone? Find Out Now!

What separates the F1 Play from its competition is the incredible 48MP rear camera. You will need to update the F1 Play to take full advantage of this though, but once you do, this camera takes awesome pictures.

Onto the battery life, and we’ve got 5150mAh’s to play with. This means the F1 Play will easily last for 2-3 days and with this big battery comes an impressive 18w fast charger which will give you a 40% charge in less than 30 minutes.

While not as value-driven as the UMiDigi Power above, we do see a big performance jump thanks to the MediaTek Helio P60 mobile chip. The 64GB’s of onboard storage can also be expanded up to 256GB SD, but you’ll have to sacrifice that 2nd SIM slot.

If you were looking for a OnePlus alternative at around half the price, the F1 Play has you covered.

Vernee X2 – 6350mAh

It makes more sense to call this phone the Vernee X1 Lite, as that’s exactly what is it. It halves the RAM, the storage and the resolution of the super-popular Vernee X1, and then passes those savings onto you.

At around 60% the cost of the X1, the Vernee X2 is a great deal for anyone who needs a budget smartphone that’ll still be powering on well into your 3rd days use.

What makes this a great budget option for the battery-life connoisseur is the better-than-expected dual rear cameras. It’s easy to shoot crisp & vivid photos outdoors and you even have the option for 1080P video recording.

In terms of build quality, you get the signature Vernee metal body design. And while it’s not slim at 10.1mm thick, we can forgive this phone as it’s hiding that humongous 6350mAh battery.

Yes, there’s no denying that the design is a little 2018, but if you’re not a fan of the notch, then this a solid long battery life option.

UMiDigi S3 Pro – 5150mAh

Or should I say… UMiDigi F1 Play – Ceramic Edition? Specs-wise, the two phones only differ in the camera department. In terms of build quality, the S3 Pro uses a ceramic rear battery cover, but at the cost of 23 extra grams in weight.

Rather than a Samsung lens in the F1 Play, the S3 Pro uses one of Sony’s legendary IMX lens for both the rear and selfie cameras. We still see the ridiculous 48MP capture size but this time it also backed up by a 20MP Sony IMX selfie snapper as well. If you see yourself as a shutterbug, but don’t want to sacrifice any battery life, the S3 Pro is for you.

Doogee BL9000 – 9000mAh

While the Doogee BL9000 isn’t to everyone’s taste, with those angular corners and that faux leather texture, we can’t deny that it’s packing some serious tech credentials!

It uses a 5.99″ Full HD+ display made by LG for excellent viewing angles and rich vibrant colours. The dual rear camera setup uses the new 12MP Sony IMX486 for the main lens with a respectable 5MP backup which will add depth of field (bokeh).

The downside to such an outrageous smartphone is that it’s a beast, at 13.8mm thick and weighing in at a hefty 275 grams.

If you don’t mind large smartphones, then the BL9000 is a worthy upgrade!

It’s doesn’t let anything slip in the camera department either coming with the impressive Sony IMX230 21MP snapper.

All this power does come with some drawbacks though, the main one being the hefty 330 grams that the Ulefone Power 5 weights.

Motorola Moto E5 Plus – 5000mAh

Compared to some of the big-battery competition, you might feel a little short-changed with the Moto E5 Plus. That’s not to say it doesn’t have its pros, it just has adopted the latest mobile trends.

Since its missing NFC, still using the old Micro-USB port and features a rather underwhelming resolution for the large 6″ display… it’s all going to come down to the price.

Onto the Pros and we’re getting a 5000mAh battery with Motorola’s TurboPower 15w charging which promises 6 hours of battery life with only a 15 minute charge.

Motorola have also used a water repellent coating to help protect the Moto E5 Plus from spills and rain. Be aware though, it’s not an official waterproof rating but will probably protect itself from your coffee spills.

Taking a look at performance and it’s again on the low-end with Qualcomm’s most basic chip the, Snapdragon 425. It’s backed up by a healthy 3GB of RAM and the 32GB of storage is expandable up to 128GB’s.

One area the Moto E5 Plus does have going for it, is in the design department. The curved edge of the back and lack of any antenna wires makes it one good looking phone.

It comes with Android 8 out of the box and full UK 4G support. It’s currently a pre-order smartphone, but we’ll update with more details soon.

Which Smartphone has the best battery life?

The smartphone with the longest battery life used to be the Doogee BL12000, which featured the Guinness World Record-breaking 12000mAh battery.

Fast forward to 2019 and the Energizer Power Max P18K blows it out of the water with a ridiculous 18000mAh battery. All-while featuring flagship credentials such as a popup selfie camera and tiny bezels.

What does my smartphone battery life get worse over time?

There used to be a time when all smartphone batteries were removable. The shops were stacked with replacement batteries and it wasn’t uncommon to carry a spare, swapping out the dead battery when needed.

If you understand how batteries work, then you’ll know that they come with a limited lifetime, also called cycle count, before they start deteriorating. After around 100-200 cycles you’ll be losing anywhere between 10 & 25% of your battery life depending on the quality of the battery.

The reason for this battery life decline is down to chemistry. Lithium-ion batteries use a cathode and anode to move the charged ions. Eventually, charging begins to wear out the cathode which gives you less overall charge capacity.

Now that a lot of batteries are sealed inside phones, you’ll want to do everything you can prolong the life of your battery. There’s actually an easy way to do this on any phone using an app called AccuBattery.

The most damaging part of any charge cycle is when the battery drops below 20% and above 80%. These two extremes are where most of the battery-life wear is caused.

This app helps by automatically setting up alerts to remind you to unplug your phone when it hits 80% and not letting the charge drop below 20%. By doing this you can effectively double the usable lifespan of your device.
