The phone with best battery life: meet the surprising new champion

When you ask people which aspect of the modern smartphone they want improved the most, the answer you'd hear from practically everyone is 'better battery life'.

The search for longer lasting phones has pushed some niche manufacturers to offer phones with extremely large batteries, but those often end up being too thick and not so practical in daily use.

There is a new crop of phones, though, that don't compromise design, and are still able to offer a huge battery. Chinese phone maker Xiaomi for once has impressed with its dirt-cheap Redmi and Mi Max series that deliver outstanding battery life.

However, there is a new champion in town and it's a surprise. The LG X Power, a dirt-cheap 5.3" Android phone with a 4,100mAh battery that is coming to Cricket Wireless soon (none of the major carriers will carry it), has absolutely ravished our battery rankings and has topped them in one go.

With a battery score of 15 hours and 18 minutes, it has more than double the battery life of trendy phones like the Samsung Galaxy S7 Edge. Heck, even the long lasting Apple iPhone 6s Plus and Galaxy Note 7 can't hold a candle to this cheapo gadget. Keep in mind that we test all phones on equal terms at 200 nits of brightness. At the same time, let's not forget that the iPhones and Galaxies we mention are high-end affairs with beautiful high-resolution displays, fast system chips and tons of other features and design flare that are not present on the LG X Power, which is just a cheap phone with large battery.

Still, it's remarkable that LG promises two days of battery life on this gadget (and we actually won't be surprised if those who are not glued to their smartphone screens all the time to get three and maybe even up to four days on a single charge).

Should you then consider buying the LG X Power? Yes, if you're looking for a cheap phone with great battery, but not so much if you're looking for just the best all-around phone. Being an affordable device, the LG X Power is - ironically - underpowered when it comes to performance with its MediaTek MT6735 system chip, it's got very scarce storage allowance, and its screen is bluish. Yet, it's still remarkable how long it lasts, and this alone might win some buyers.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Neh, the S5's pimples were more noticeable, especially on the bandaid edition...had to zoom into this to even find the similarity.

I'd consider it if there were an unlocked version that is fully compatible with T-Mo.

A whole article about battery life and Victor doesn't even mention the battery capacity let alone resolution of the respective phone.

4100mah. 720P.

It's not surprising then lol. That kind of capacity with that screen and low power processor makes up for amazing battery life.

And it's great battery life can't be relevant versus the battery life of flagships!

This is a typical user battery test, so the people that say they get 1 or 2 day battery life what are they doing? I get around 8 h if I'm lucky from my 1 year old Samsung s6. We don't need thinner phone 's.

Why a Mediatek/Snapdragon 212 tho... What a waste.

Okay the mediatek...I'll pass it. But here in Canada it comes with the 212...I would have taken a 410 anyday.

Well strange at Telus we have the mediatek based one. Must depend on carrier.

MT6735, eh? Well, Cortex-A53 is by far the most power efficient 64-Bit ARMv8 core currently in production... Only behind Cortex-A7 which BTW is based on 32-Bit ARMv7 Architecture and has considerably poorer performance and most A7 SoCs lack LTE (MT65**, Snapdragon 200/210)... Tell you what, my Lumia 430 will likely beat this LG X-power cause it has an SD200 with an A7 Dual Core, 4" Display & FWVGA Resolution...!

13. sarcastic_nerd unregistered

The lumia won't even come close due to older screen tech and low capacity battery. Also A53 is successor of A7, it's a bit more efficient.

Before speaking you should check your info. I work at Telus in Canada and we have thats phone : Look in specification... magic its support LTE! Its also beat the SD410 in all benchmark. So before hating look up the info.

So the secret to long battery life is a large battery, weak CPU, little storage and small low resolution screen. What a surprise. But what good is a phone with such limited power?

thats phone can run any mainstream game even pokemon Go. you need beefy cpu/gpu for high resolution screen if you sacrifice the resolution you can get okay performance from lower end stuff. So what good this phone is.. Making calls. Checking emails. Navigating the web. Facebook and other social media. Mainstream games. Its not because you need a flagship thats everyone do!

I watch allot of live streaming video, play HD movies and record in 1080p and 4K. I also play 4K movies since I have a 4K screen on my phone. I do not think this phone's weak processor and low resolution screen will be sufficient..

lol but then certainly this isnt phone made for you,you need to seek high-end phone,not a mid ranger,its all about priorities,not everybody needs 4K recording and watching 4K content

But graphics-intense games will lag alot. It isn't only about 4K videos.

i highly recommend to read my last sentence. I dont say you dont need thats but not everyone do. I personaly use a LG G5 because i am a heavy gamers and love nice graphic and i also like taking nice picture and movies. But not everyone have those need. Many play game like candy crush ect those will run very well on this phone. also up to 1080p streaming work perfectly well on it too. This is like you would bash on a car company because they made a compact car ( when you need a sports car ) make no sense.

Why wasn't the s6 active included with the original comparisons? It gets more than an hour better battery life than a s7 active...

Good but overall all Samsung phones with marshmallow or higher has excellent battery life. Still remember the time z3 compact got the battery life endurance crown. Now sony is not so good. But not bad. LG has done good job. Well done

Samsung S6 has horrible battery life. Samsung S7 is okay. Not all of them have amazing battery life. Samsung core are very bad.
