For many years, if you wanted a Samsung phone with the best battery capacity, you had to settle for a model with a 3000mAh + battery. Competitors launched smartphones with big batteries, Samsung was one of the long-standing brands that would not budge and jump in. As such, when mobile users who needed big, fat batteries went shopping, they inevitably ended up with products from other brands.
For a long time, it was difficult to find a Samsung smartphone with a 4000 mAh battery, talk less of a 5000 mAh one. But times have changed. This is 2019 and the new Samsung has the A series phones taking on the competition on all fronts – including high-value budget phones and now big battery phones.
- The Samsung phone with the best battery in 2019 is the Galaxy A40s or M30

The Samsung phone with the best battery in 2019 is the Galaxy A40s or M30
The Samsung Galaxy A40s, also known as Samsung Galaxy M30, is an iteration of the Galaxy A40. It packs a Super AMOLED touchscreen display of 6.4 inches in size and 1080 x 2340 pixels in resolution, runs Android 9 Pie, is powered by a respectable Exynos 7904 processor coupled with 4GB or 6GB RAM, and keeps all those lit up with a whopping 5000 mAh battery.
To make sure that you can top up that big battery quickly, there’s 15W fast charging built-in. Samsung has been stuck on 15W fast charging for years, that one begins to wonder. But 15W Quick charging is better than no quick charging, so we will rejoice and be glad. So if you are hunting for the Samsung phone with the best battery capacity, this is it.
Being a phone designed for long-lasting use does not mean that it is useless in other areas. The rear camera is a triple lens affair, the selfie camera is a 16MP affair, there is a rear-mounted fingerprint reader, and the USB connection is Type-C.
There is also dual-SIM support, a dedicated micro-SD card slot, FM radio, 4G LTE connectivity (though a little limited), and more. On the software side, Samsung’s new One UI is a delight to use, and I have since become a huge fan of the user interface and experience.

Samsung Galaxy A40s is also known as Samsung Galaxy M30, is hands down the Samsung phone with the best battery capacity.
Samsung did not skimp on this one. The Galaxy A40s (or Galaxy M30, depending on the country you are in) is a well featured smartphone for road warriors and anyone who needs to be away from a charging point for long periods. You should not have any problems squeezing a full day of use out of it.
We have the full Samsung A40s specifications for you to go through for a more detailed view.
Price and Availability
So how much does this road warrior cost? As mentioned earlier, there are two variants – one with 4GB RAM and 64GB internal storage, and the other with 6GB RAM and 128GB storage.
In Nigeria, the 4 GB RAM variant is available for N82,000, while the 6 GB RAM version is available for N90,000.

Samsung Galaxy A40s has a big 5000 mAh battery and fast charging, making it the Samsung phone with the best battery.
The Samsung phone with the best battery life in 2022
Fast-forward to 2022, and there are a handful of Samsung phones now available with even larger batteries and better battery life. The Galaxy M31 and M32 are successors to the M30 we recommended in 2019. All these smartphones have a 6000mAh battery, and they aren’t even the baddest toys on the block.
Consider the M51 and M62, with 7000mAh batteries. These are the Samsung phones with the best battery capacity in 2022. These phones can go for days on one charge. What will it cost you to get one. Expect to spend around $450.
This is the point where I ask, What are you still waiting for? If you have been hunting for this vital information about the Samsung phone with the best battery and that delivers long-lasting battery life, the ball is now in your court.

There are scores of LTE bands available and being deployed in different regions and countries all over the world. There is no failsafe way to ensure that a 4G phone will support all available LTE networks in any region or country.
However, if you are travelling to Europe, there are certain bands that are widely deployed there, and you would be safe to have a 4G phone that supports those bands.
- European 4G Bands: What LTE bands are used in Europe?
European 4G Bands: What LTE bands are used in Europe?
The most common 4G LTE bands used in Europe are:
- LTE 1(2100),
- LTE 3(1800),
- LTE 7(2600), and
- LTE 8(900)
As such, any smartphone or feature phone that supports the above 4G LTE bands is fairly safe to roam around Europe with.
In addition to the above bands, the following bands are also fairly commonly deployed by European 4G network operators:
- LTE 19(800),
- LTE 20(800),
- LTE 28(700),
- LTE 38(2600), and
- LTE 40(2300)

If you have a smartphone that supports all above-listed European 4G bands, you are pretty much covered and unlikely to ever be unable to connect to 4G broadband while on the old continent.
