Best Battery Life Phone 2021: Apple, Samsung, One Plus

It’s 2020 and smartphones are as important in our daily lives as other necessities like food and water. From booking cabs to checking the weather for rain, from reading the news to checking for important emails, from watching movies while stuck in a traffic jam to listening to music on a walk, we depend on our smartphones for almost everything.

In such a scenario, there is nothing worse than a smartphone which can’t last long enough to do all the things you would want and expect from a smartphone. Most phones today may be able to last through a day, but some of them aren’t even capable of that when subjected to heavy use.

Unlike other smartphones specs such as the processing power, display, design, technology companies haven’t made any major breakthroughs in the battery department. A smartphone is meant to be a portable computer and if it can’t run like one, it is pretty much useless.

Here, we have compiled a list of some of the smartphones with the best battery life that don’t compromise on the specs either. While some of these manage this through giant batteries, others rely on some software trickery to squeeze out more life from a battery.

Apple iPhone 11 Pro Max

Immensely powerful, great camera, fantastic battery life.

iphone 11 pr max

iPhone 11 Pro Max

Performance – The iPhone 11 Pro Max is packed with Apple’s A13 Bionic chip, one of the most powerful processors to be packed in a smartphone ever. It features two high-performance cores for heavy tasks, coupled with two low-power cores for less processor-intensive tasks. This combination is what gives the 11 Pro Max an incredibly long lasting battery life and blisteringly fast performance. It is also Apple’s first phones to come with 4 GB of RAM, and it shows when you use the phone!

Camera – The industry-leading camera in the iPhone has got even better with the iPhone! This time, Apple has used a triple 12MP cameras with Portrait mode, Depth Control, Portrait Lighting, Smart HDR, and 4K video up to 60 FPS.

Display – The 6.5-inch Super Retina HD display with XDR and True Tone is now capable of displaying a much wider color gamut. Like its predecessor, it also has 3D touch which now feels slightly more natural than before.

Design – The 11 Pro Max is more of an evolutionary change than a revolutionary one in terms of design. The antennae lines have been moved. The biggest design decision remains the omission of the headphone jack, which can be a deal-breaker for some.

Battery – The one area where the 11 Pro Max is noticeably better is the battery life. It can last a full long day of heavy usage without urging you to run to your charger. Since you can’t use a wired headset while charging the phone simultaneously, the added battery life is a great relief.

Beautiful, blazing fast, amazing always-on display, best in class camera.

Samsung Galaxy S20 5G

Samsung Galaxy S20 5G

Performance – The international version of the Samsung Galaxy S20 comes with Samsung’s own blistering fast Exynos 8890 processor.

It can open a ton of apps without stuttering, play games at their best quality, and breeze through almost anything you throw it. Samsung’s phones are known for being fast, and the S20 is the fastest of them all right now.

Camera – The Samsung Galaxy S20 has one of the best smartphone cameras today, if not the best. Its 10MP Selfie Camera: Dual Pixel AF, Pixel size: 1.22μm, FOV: 80˚, F.No (aperture): F2.2 and Rear Camera: 12MP Ultra Wide Camera, 12MP Wide-angle Camera, 64MP Telephoto Camera.

Design – The Samsung Galaxy S20 is simply one of the best-designed phones available today.

Battery – The S20 comes with a giant non-removable 4000 mAh battery that will work easily you get through a day of heavy usage (and some more too).

OnePlus 6T A6013

Incredibly cheap, high-quality build, solid camera.

OnePlus 6T A6013

OnePlus 6T A6013

Performance – Touted as the flagship killer, the OnePlus 6T A6013 is one of the best budget Android phones available in the market today. It comes with Qualcomm’s Snapdragon 820 processor, but it is one of the first smartphones ever to be equipped with 8 GB of RAM. That combination makes it one of the swiftest Android phones available in the market, even faster than Samsung’s flagship.

Camera – The Dual Rear Camera: 16MP (f/1.7) + 20MP (f/1.7) Dual LED Flash on theOnePlus 6T A6013 is quick, fast and simple. It captures great shots and won’t miss anything. It may not be as good as Samsung’s and Apple’s best, but the difference is barely noticeable.

Display – The 6.41 inch Optic AMOLED display is bright and sharp. It also comes with a Night mode to reduce eye strain when looking at the screen in the dark, a feature recently introduced by Apple as well as Google in their latest operating systems.

Battery – The 3700 mAh battery in the OnePlus 6T A6013 is non-removable and is good enough to last a long heavy day. It isn’t as good as Samsung’s, but it is so close that it doesn’t matter. Moreover, it comes with Qualcomm’s QuickCharge 3.0 that can charge the phone from 0 to 65 percent in just half an hour.

ASUS Zenfone 5Z

Incredibly long-lasting, inexpensive.

ASUS ZenFone 5Z

ASUS ZenFone 5Z

Performance – A mid-ranged smartphone, the ASUS Zenfone 5Z won’t win any awards in the performance department. It comes packed with a Qualcomm Snapdragon 845 – Octa-core 2.8Ghz and 6 GB of RAM. The phone is good for most basic tasks but don’t expect it to be a powerhouse or play graphic-heavy games on it. The Zenfone 5Z is an average phone with a heavy battery, and its specs reflect that completely.

Camera – It comes with 8MP Front Cameras and 12MP with OIS/EIS+ 8MP Wide-angle Rear Cameras. It will output decent shots with sufficient light, but low light performance is a disappointment.

Display – The Zenfone 5Z has a 6.2″ IPS FHD+ Full View Display (2160×1080).T he resolution is too good for a display this big and while the outdoor performance was good, viewing videos isn’t a pleasant experience on this phone.

Design – It is a black slab of a phone made of plastic. It isn’t exactly disappointing, but nor is it exciting.

Battery – The only thing this phone gets right is the battery; a 3.3000 mAh behemoth. Thanks to that, this phone can easily last two days on a single charge.What’s more, you can even use it to charge other smartphones.

Motorola Moto G7 Power

Inexpensive, a great phone overall, durable.

Motorola Moto G7 Power

Motorola Moto G7 Power

Performance – The mid-range Motorola Moto G7 Powerc omes with a decent Qualcomm Snapdragon 632 octa-core processor. Equipped with 3 GB of RAM, it is also mildly swift and fits in perfectly in the Android mid-range market. Regarding performance, it will handle almost any basic smartphone task. However, it does sometimes struggle when multiple apps are open or when performing a processor-heavy task.

Camera – Motorola outdid itself with an excellent Fast-focusing 12 MP camera in the G7. The camera is impressively good for a phone in this price range and the only area where it suffers slightly is in low-light. To account for that, it is equipped with a two-tone flash for capturing softer skin tones without causing blow-outs.

Display – The 6.2″ Max Vision HD+ display on the Moto G7 is simply fantastic. It is not QHD, like some of the higher-end smartphones, but the lack of it means a better battery life as well as better performance. Apart from that, the phone’s display is pretty good. It will even allow you to switch between two modes; ‘Normal,’ with more realistic colors, and ‘Vibrant,’ with enhanced vibrancy and color saturation.

Design – The Moto G7 is instantly recognizable as a Motorola phone. The front is simple and clean while the back features a plastic patterned back. It feels somewhat cheap but adds to the durability of the phone. It is considerably thick at 9.3 mm but the back is also slightly curved, making the phone feel fit easily into your hands.

Battery – The Moto G7’s non-removable 5000 mAh is big for a budget phone, even for a phablet-sized phone like this. It can last a little over a day of heavy usage and maybe, even two days if you are not a heavy phone user.

Xiaomi Mi Note 10

Outstanding battery, rapid fingerprint sensor, exceptional build.

Xiaomi Mi Note 10

Xiaomi Mi Note 10

Performance – The giant-sized Xiaomi Mi Note 10 packs in giant-like specs as well. It has a Qualcomm Snapdragon 730G processor and 6GB of RAM. It can switch between apps with zero lag, play graphic-heavy games without a single stutter and handle the whole operating system fluidly.

Camera – The main camera on the Mi Note is the 108MP ultra high-resolution camera + 12MP portrait camera + 5MP telephoto camera + 20MP ultra wide-angle camera + 2MP macro camera and the front Camera is 32MP selfie camera – 4K recording – 1080P slow motion recording – Vlog mode & Night mode 2.0

Display – The Mi Note 10 offers a 6.47″3D curved AMOLED display Corning Gorilla glass front and back. The display would suit better for such a big display, the lower resolution does help regarding squeezing out more battery life from the phone.

Battery – The one feature that makes the Mi Note 10 stand out from the other bunch of huge smartphones is the battery life. Powered by a whopping 5260 mAh battery and a slightly low-resolution FHD display, the phone can even get you through 2 days of moderate usage. The battery life is simply excellent, and you would be hard put to make the phone die down in a single day, even with extremely heavy usage.

Google Pixel 4

Beautiful, stock Android, fast updates.

Google Pixel 4

Google Pixel 4

Performance – The latest and best Nexus to date, the Google Pixel 4 is Google’s vision of what a smartphone should be. It is powered by a Qualcomm Snapdragon 855 processor and a handsome 6GB RAM. Although it came out last year, it remains one of the fastest and most fluid Android phones, thanks to stock Android. It is also one of the very few phones to have Android 10vrunning on it.

Camera – The Google Pixel 4 has the Rear cameras – Dual: 12.2-MP primary wide (ƒ/1.7); 16-MP telephoto with 2x optical zoom (ƒ/2.4) and the front camera – 8 MP (ƒ/2.0). Overall, it has a really good camera that will perform well for almost any situation, including low light.

Display – Equipped with a 5.7-inch OLED with 90-Hz Smooth Display (2280 x 1080), the Pixel 4 has one of the best displays on the market today. It is an OLED display and sufficiently bright for outdoor use as well.

Design – Unlike previous Nexus devices, the Google Pixel 4 is made to be premium. It is solidly built from aluminum and has smooth, rounded edges that make it a pleasure to hold. There is a big camera bump on the back but they have made it a part of the phone’s design.

Battery – It comes with a decently large 2800 mAh non-removable battery. Alongside Google’s battery tweaks in Android 10, that battery makes for a fantastically long-lasting smartphone.

Things You Should Consider Before Buying Smartphones

When considering a smartphone, there are some things to take into consideration. However, since our major concern for this article is the smartphone that can last the longest, the first thing we will look at is the size of the battery.

1. Battery Life

Smartphones With The Best Battery Life

The battery life of a smartphone depends on many factors. Simply put, the bigger the battery will be, the longer it will last. On the other hand, the larger the display is, the amount of power it will draw will be as big and will have an opposite effect on the battery life. The perfect recipe for a long-lasting phone is to have a giant battery and a standard average-resolution display.

2. Display

As stated above, the display is the biggest factor in determining the phone’s battery life (apart from the battery itself). The phone’s display can be responsible for taking up as much as half the power.

3. Specifications

Smartphone specifications are a must when considering any phone. There is no point of buying a low-powered smartphone that can last longer if it won’t be good for your usage.

4. Design

Smartphones with big batteries usually tend to be a bit on the thicker side. Still, that is no reason to compromise on the quality of the design, and most modern flagships have managed to find the perfect balance between design and battery size.

5. Camera

Smartphones With The Best Battery Life

We use our smartphones as our daily photography devices too. Fortunately, most smartphones today have cameras that are good enough not to force us to carry separate cameras.

6. Brand

Today, your smartphone choice is almost as important as your choice of clothes. Our phones portray our sense of brand and likeness. Recently, some Chinese brands have also flooded the markets with ultra-cheap and genuinely great phones.


Smartphones With The Best Battery Life

Up until a couple of years ago, it was hard to buy a flagship phone and still expect it to last through a full day of heavy usage. However, things have changed pretty quickly, and smartphone manufacturers have realized the need for a big battery as well as more powerful specs.

Today, you can pick almost any flagship phone from a popular smartphone manufacturer, and chances are, it will easily last you through a day. Moreover, there are phones like the Huawei Mate 8 and the iPhone 7 Plus which will even make it through to the next day before giving up. Not looking for a powerful phone but want a bigger battery? You still have a choice in the form of the ASUS Zenfone Max.
