Top smartphones of 2018 with big batteries

null

A decent battery is the root of any smartphone worth its salt. It ensures that you can get the most out of your phone during any point of the day, without worrying about battery drain. More importantly, its the underlying factor behind whether or not you can listen to tunes on your device when you're on your way home after a long day at work.

Quite a few phones that go all out with their features, forget to back it up with a big battery. But, there are still ample options in the market that fall within the mid-range or budget segment. 

Keep in mind that battery size alone isn't the determining factor for a smartphone's battery life. The phone's chipset and a consumer's usage pattern also have a big part to play.

Big phone with big battery

Weight: 180g | Dimensions: 159.00 x 76.00 x 8.46mm | OS: Android 8.0 Oreo | Screen size: 5.99-inch | Resolution: 1080 x 2160 | CPU: Snapdragon 636 | RAM: 3GB | Storage: 32GB | Battery: 5000mAh | Rear camera: 13MP | Front camera: 8MP

Camera acts up from time to time

The Asus Zenfone Max Pro M1 is the newest member of this list with its mega 5000mAh battery. Though the phone is equipped with a big battery, it doesn't last as long as you'd expect it to, but it crossed the 24 hour threshold nonetheless. 

Keeping in mind that the phone only costs Rs 10,999, it's a decent option that runs on Stock Android offering an above average user experience. The company highlights the phone's audio feature, which is considerably loud, but isn't necessarily 'better'.

Also, keep in mind that the phone doesn't support fast charging. Even so, the review unit displayed 'charging rapidly' and did indeed charge 'rapidly'.

Overall, the phone has more features than other phones in the same price range and quite honestly, running on a pure version of Android is definitely a heavy selling point.

The Redmi Note 5 Pro is an incredible smartphone for its price point. Even after heavy usage through out the day, the battery won't run out in the span of 24 hours. Idle battery life will last for quite a while. 

The camera performs well, the SoC boosts efficiency and the option for expandable storage make things a lot easier.

It may be the cheapest of the range, but the Moto E5 still packs a sizeable 5.7-inch display with a tall 18:9 aspect ratio display, Qualcomm Snapdragon 425 chipset, 2GB of RAM, 16GB of storage, 13MP rear camera, microSD slot and a rear facing fingerprint scanner.  There's also a big 4,000mAh battery, stock Android 8.0 Oreo interface, headphone jack and a 5MP front facing camera. Not bad for the price, but the competition is really tight around this price.

Not USB type-C
Dated design
Still runs on Nougat

Just like its predecessor, which was previously on this list, Redmi Note 5 also comes with a battery capacity of 4,000 mAh. The phone lasts comfortably on a single charge for a whole day under heavy usage. If you use your phone with moderation, the battery will last even longer. 

It takes around two hours to fully recharge using the regular 5V adapter provided in-the-box.

But if you already own a Redmi Note 4, then refrain from the upgrade because very little is different in the two variants. They even run on the same chipset.

After launching the Srt.phone, India based Smartron has launched a budget smartphone in the country with a big 5,000mAh battery. While the device does not offer powerful hardware, it is good for a secondary device for all-day use priced at Rs. 7,999.

While the device is being offered as a budget device, it does not feel cheap at all. It features a metal body with plastic bands at the top and bottom and features a fingerprint sensor at the rear.
