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 Smartphones with the added benefit of waterproofing, drop-protection and uber-ruggedness.

With smartphone battery life still being a real pain in the you-know-what. It really gets on my nerves when a phone constantly needs topping up throughout the day.

What Smartphones Have The Best Battery Life in 2019? Let’s find out!

UMiDigi Power

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.

That alone, makes the UMiDigi Power one of the best all-rounder mid-range phones in this list. The large 6.3″ display is Full HD, it’s also thin at 8.8mm, and finally, 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 so it won’t be destroying your pockets like the P18K below.

The team at UMiDigi know that their fans 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 5000mAh+ later on in this list.

Also good news, that’s going to please you stock Android enthusiasts, is that the Power 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 +256GB’s).

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

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

Samsung Galaxy A40s

Finally, Samsung has realised that we want big batteries in our smartphones! 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 less pixels to push around, so you’ll be getting at least 50% more screen time.

The triple camera setup with dedicated wide-angle snapper has also trickled down into the A40s, although don’t expect flagship level quality. What you can expect is Samsung’s epic build quality, a reasonably thin (8.5mm) frame and in a lightweight package (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 it might be worth hanging on for a few months before diving in.

Battery Capacity: 5000mAh
Battery Life: 2 Days

Xiaomi Mi Max 3 Display

Xiaomi Mi Max 3 – 5500mAh

Update: While now a little older, I’ve left the Xiaomi Mi Max 3 on this list as it’s still a great value phablet.

The Xiaomi Mi Max 3 has a respectable 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 6.9″ display is Full HD, its slim at 8mm and is asl featherweight at only 221 grams (size-considered). I’ve reviewed plenty of 5.5″ smartphones that weigh more than the Mi Max 3.

It also features a healthy 4GB’s of RAM and 64GB’s storage with a Snapdragon powered chipset. The 8-core mobile processor is great for speed and productivity but not exactly a gaming powerhouse.

I think that Xiaomi knows this, so if you’re looking for a big battery gaming smartphone then hold off for now. I’ve got a feeling Xiaomi has planning big things for the next Mi Max 4.

For more details, check out our full Xiaomi Mi Max 3 Review.

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
Battery Life: 2 Days
Battery Capacity: 5500mAh
Quick Charge: Yes
Weight: 221 grams

Cubot Max 2

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 uber-battery life smartphone, the Cubot Max 2.

I was a bit sceptical at first, but that was only until I realised that square notches are loved by dolphins all over the world. #OfficialCubotMarketing

You can think of the giant 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
Quick Charge: N/A

Motorola One Power

Originally called the Motorola P30 Note, the re-named Motorola One Power has a lot to offer. Made in partnership with Google’s Android One program, the One Power is part of an exclusive club that is the first to receive security updates and is also guaranteed to update Android 10.

The display itself is a 6.18″ full HD panel which offers crisp and punchy images thanks to that high PPI of 403. Although inside, we find the low-to-mid-range Snapdragon 636 which might leave some feeling a little disappointed. While fine for multi-tasking, its gaming performance is lacklustre.

Onto the battery life and the 5000mAh cell is backed up by Motorola’s Turbopower charging technology which promises 6 hours of use time from a 15 minute charge.

Battery Capacity: 5000mAh

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 longest battery life of any phone ever to make it on to this list.

Normally these types of phones are more marketing-stunt than real-life viable products… not so with the Energizer Power Max 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.

This phone could have been an absolute legend, but it’s missing one important key feature: waterproofing.

Nobody in their right mind would want the P18K as a daily driver, but, as an epic adventure phone? Oh Yes! I want to be writing about this phone in our Best Tough & Rugged Smartphones List.

Who knows, maybe they’ll bring out a Power Max P18K adventure case?

But back to that nagging feeling… couldn’t I just carry a power bank…

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

UMiDigi F1 Play

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

What separates the F1 Play from the mid-range competition is a 48MP rear camera. You will need to update the F1 Play to take full advantage of this though, but once you do, this camera snaps beautifully.

Onto the battery life, and we’ve got a 5150mAh non-removable cell which will easily see you into your second day of usage. 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 bump 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.

Battery Capacity: 5150mAh
Battery Life: 1-2 Days
Quick Charge: Yes (18w)
Wireless Charging: No

UMiDigi F1 Play – Style & Battery Life

UMiDigi S3 Pro

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 Sony 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.

Unless you just have to have the premium ceramic build, then I’d be tempted to stick with the F1 Play above.

Battery Capacity: 5150mAh
Battery Life: 1-2 Days
Quick Charge: Yes (18w)
Wireless Charging: No

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

Top Tip: While not one of the latest generation of smartphones, the Cubot Power still has a lot to offer. Mainly the price and the epic battery life. It was a firm favourite when released in 2018.

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
