Best Battery Life Power

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?‘.

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 2019? Let’s find out!

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.

Nubia Red Magic 3 – 5000mAh

The Nubia Red Magic 3 is one heck of a smartphone. It’s tailored towards gamers, but the flagship-level specs, all-metal build and massive 5000mAh battery have massive widespread appeal.

You can check out more details on the Nubia Red Magic 3 over in our Best Gaming Smartphones List as well as some other great options.

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.

Tip: You can expect the price to drop fast, so hang on a few months before for some big savings!

Xiaomi Mi Max 3 Display

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!

Related: The Best Xiaomi Smartphones – 2019 Edition

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

Xiaomi Mi Max 3 Beast – Available Now

Cubot Max 2 – 5000mAh

If you’re sick of notches, punch holes and teardrops… why not try the ‘Square’ corner notch? Well, that’s what Cubot’s design team thought when creating their latest big battery phone, the Cubot Max 2.

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.

Battery Capacity: 5000mAh
Battery Life: 1-2 Days

Motorola One Power – 5000mAh

Originally called the Motorola P30 Note, the re-named Motorola One Power has loads to offer. Made in partnership with Google’s Android One program, it’s guaranteed to receive monthly Android security updates.

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.

Battery Capacity: 5000mAh
Battery Life: 1-2 Days

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.

Battery Capacity: 18000mAh
Battery Life: 6-8 Days
Quick Charge: N/A
Wireless Charging: No

Want more power than Thor in your pocket?

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.

Battery Capacity: 5150mAh
Battery Life: 1-2 Days
Quick Charge: Yes (18w)

UMiDigi F1 Play – Style & Battery Life

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.

Battery Capacity: 6350mAh
Battery Life: 2-3 Days
Quick Charge: Yes (10w)
Wireless Charging: No

Vernee X2 – Available Now

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.

Battery Capacity: 5150mAh
Battery Life: 1-2 Days

Cubot Power Smartphone

Cubot Power – 6000mAh

Cubot haaaaaassss theeeeee Powwwweeerrrrr! When Cubot first announced the Power, I was taken back by the sheer specs of the phone. Cubot had killed their own flagship device, the Cubot X18 Plus

Good news for us though, as it’s packing the Helio P23 8-Core MediaTek CPU with plenty of RAM. The storage is a whopping 128GB, and the display is Full HD+.

This is all before we even get to the fact that it’s got a 6000mAh fast charge Type-C powered battery. It’s one hell of a phone. Check out our full Cubot Power Review here.

Oh, and did I mention that there’s a 20MP Samsung camera strapped to back of the Cubot Power? A

All this power comes at a high price though, see below.

Quick Specs: Android 8.1 Oreo, MediaTek Helio P23 (8 Cores @ 2.5Ghz) CPU, 6GB RAM, 128GB Storage, 5.99″ 1080 X 2260
Battery Life: 2 Days
Battery Capacity: 6000mAh
Quick Charge: 2amps
Weight: 216 grams

Vernee X Smartphone

Vernee X1 – 6200mAh

The Vernee X1 doesn’t compromise. It’s available in two variants offering up to 6GB of RAM’s and 128GB’s of storage coupled with MediaTek’s next generation Helio P23 CPU. While not a powerhouse, it offers extreme mid-range efficiency.

This is then combined with a massive 6200mAh battery making it one of the best long lasting smartphones available.

You’re also getting a full HD+ 18:9 display that comes with curved corners, a metal unibody design and a quad camera setup. Thanks to the high-resolution 13MP selfie camera, we’re also treated to Vernee’s face unlock feature.

Overall, the Vernee X1 is a great all rounder that’s packing some serious battery without weighing you down.

Quick Specs: Android 7.1 Nougat (upgrade to Android 8), MediaTek Helio P23 CPU, Mali-G71 GPU, 4/6GB RAM, 64/128GB Storage, 5.99″ 2160×1080 IPS Display

Doogee BL9000 Smartphone

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).

Related: What’s the best Doogee Smartphone?

Other premium features we see on the BL9000 are Wireless Charging and NFC which are traditionally reserved for flagship devices.

Now onto the battery. Yes that’s right, under the hood is a 9000mAh battery that will easily last 2 days of power usage and 3-4 of light usage. For a massive battery like this, you need some serious charging power and it comes in the form of PumpExpress 4.0 (5V/5amps).

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!

Quick Specs: Android 8.1 Oreo, MediaTek Helio P23 CPU, 6GB RAM, 64GB Storage, 5.99″ LG Display, 1080×2160 resolution.
Battery Life: 3-4 Days

Ulefone Power 5

Ulefone Power 5 – 13000mAh

The thorough-bred Ulefone Power 5 comes from a long line of epic battery life smartphones. The Power 5 ups the game though by adding Qi Wireless charging coupled with 5V/5Amps fast charging.

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.

Is it worth reinforcing your jeans pocket with kevlar to behold such a powerful beast? Let me know in the comments.

Quick Specs: Android 8.1 Oreo, MediaTek MT6763 Octa Core CPU, ARM Mali-G71 GPU, 6GB RAM, 64GB Storage, 6″ 2160 x 1080

Bluboo S3 Smartphone

Bluboo S3 – 8500mAh

The Bluboo S3 offers it all in a very attractively priced package!

Out of the box, the S3 comes installed with Android 8.1, has a 6″ SHARP manufactured 18:9 full HD+ display, dual Samsung rear cameras and let’s not forget a whopping 8500mAh battery.

This is enough battery to easily see you in to your third day off-grid! All this power comes with great responsibility… if you count responsibility as a beast of a smartphone weighing down your pocket.

At 280 grams, the Bluboo S3 isn’t for the faint of heart, but if your grip is solid then the S3’s price-tag is extremely tempting!

Quick Specs: Android 8.1 Oreo, MediaTek MT6750T Octa-core CPU, ARM Mali-T860 GPU, 4GB RAM, 64GB Storage, 6″ 1080 x 2160

Motorola E5 Plus

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.

Quick Specs: Android 8 Oreo, Snapdragon 425 CPU, 3GB RAM, 32GB Storage, 6″ Display, 720×1440
Battery Life: 2 Days
Battery Capacity: 5000 mAh

Doogee BL5500 Lite – 5500mAh

The super-budget Doogee BL5500 still offers a 6.19″ HD notch-wielding display combined with a 5500mAh battery.

While the performance of the BL5500 is aimed at entry-level buyers thanks to a budget quad-core CPU and only 2GB of RAM. The good news is that the 16GB of storage can be expanded using the Micro-SD card slot.

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.

Quick Specs: Android 8.1 Oreo, MediaTek 6739 CPU (4-cores), 2GB RAM, 16GB Storage, 6.19″, 720×1500

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.

Phone with the best battery life = Energizer Power Max P18K

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.
