Battery Life

The name LG X Power can be interpreted in two ways. You might think that it means the phone is very powerful, or you might think that it has a massive battery. Of course, it could be both, but the phone would probably cost a bit more than $130 if that were the case. In the case of the LG X Power the name does refer to its battery, which comes in at a massive 15.58Wh. This is much larger than many phones that are actually thicker, larger, and heavier than the LG X Power, and I discussed in the previous section the likely reasons why LG was able to fit such a large battery into the phone.

It won't be surprising if the LG X Power outlasts every other device that I compare it to, but I did want to preface the review with our battery life tests instead of performance tests. I believe that the LG X Power's appeal will be to users who need an exceptionally long period of usage on a single charge, but it's not immediately clear based on the battery capacity alone how much longer the LG X Power can last than competing devices. The battery life advantage will have to be balanced against any potential disadvantages that the LG X Power provides, and so it makes the most sense to start off with the battery results before examining other aspects like performance, display, and camera quality.

As always, I'll begin with our internal web browsing battery test, followed by PCMark's battery test. Normally I would also include our GFXBench Manhattan ES 3.1 battery benchmark, but the LG X Power's GPU and drivers do not support OpenGL ES 3.1 which prevented me from running it.

Web Browsing Battery Life 2016 (WiFi)

In our WiFi web browsing battery test the LG X Power comes in at the top of the chart. At 12.77 hours it lasts much longer than most mid-range devices like the Moto G4 and the iPhone SE. When compared to devices of similar battery capacity like the Xiaomi Redmi Note 3 and the Meizu M3 note you can see that it only lasts a bit longer. This is important to note because while the LG X Power is a smaller and lighter device than either of those, it's not a great deal smaller, and it doesn't compare very favorably as far as specifications are concerned either.

PCMark - Work Battery Life

In PCMark's battery test the LG X Power continues its lead over the other smartphones. In this case the gap between it and the competition from Xiaomi and Meizu is much more significant, and PCMark is a good representation of the usage that a device can provide on a single battery charge, so this is arguably a more important test for the LG X Power to excel in than the web browsing test. In the following section it will also be important to make note of how the LG X Power performs in PCMark compared to those phones.

As expected, the LG X Power does well in our battery benchmarks. It would be hard to do anything else when you pair a 15.58Wh battery with fairly humble hardware, but we've seen stranger things happen with mobile devices. I don't really have much else to say here except that the phone definitely lives up to its name.

Charge Time

Smartphone charge time has been an issue in the past for mid-range smartphones. In some cases I've received chargers that aren't even your standard 5W blocks, and some were only half that at 2.5W. Thankfully we've seemingly moved past that time, and even though the LG X Power packs such a large battery one would hope that the time to charge it isn't extensive.

Charge Time

With its stock charger, the LG X Power takes about three and a half hours to go from 0 to 100% charge. Considering the size of its battery, this isn't a bad result, although the Meizu M3 note and Xiaomi Redmi Note 3 both charge a bit quicker. Given the fact that LG's charge time is similar to the Honor 5X which has a 25% smaller battery capacity there's not really anything to complain about.

    You don't understand? Money talks here. If anandtech does not receive the check from HTC, they would hold the review until the next generation is coming while no one is paying any attention to the current gen. EVEN THE REVIEWER THINKS THAT HTC 10 IS AN AMAZING PHONE Reply

    Yeah, and people are wondering why the HTC 10 doesn't seem to be selling well.

    Could it be because a very respected website appears to be stalling in publishing their review of the phone?

    In my many years of visiting this site and reading their phone reviews (some of which I agree with and some I don't), I've not seen a phone review delayed for so long. Over 3 months and counting now.

    I think we are entitled to an explanation a bit more than just "life". Whatever it is, it hasn't stopped him releasing other articles and reviews.

    It's almost like you are deliberately delaying the review now.

    I saw this phone at cricket. It surprisingly is lightweight. But the screen on it compared to the Escape 3 is horrible. I wouldn't buy it. I basically can confirm the poor light and colors tested here, and you will notice it next to other phones. Reply

    I wish my S7 or any high end phone would go 1-2mm thicker and make that entire space extra battery capacity. I really really really don't need a phone any thinner than my S7.... what I do need is a full day of USAGE on my phone.

    I have to carry a giant ass battery brick with me just to keep my S7 topped up on trips when I am driving around and going in and out of good coverage zones. I've had my battery drop from 90%-30% just driving around a national park for a few hours. This is the type of thing phone companies need to work on.... stopping massive drains and giving bigger batteries, not making a tiny phone even tinier.

    As I alluded to earlier, check A9 Pro. I go more than a day with ease. Reply

    A7????? I am a fan of inexpensive phones but this is preposterous. Reply

    When a phone like this uses a snap 212...huuuge turnoff. I wonder if it's rootable.

    And Brandon, any foresight of a Moto G play review? Kinda curious how it'll be.

    Can anyone who has this (or Brandon) use the AIDA64 app and see what camera sensor it uses? Reply

    Good idea but poor execution. If this phone had all of its limitations but 2X or 3X the battery life of everything else on the market, it might find its niche. But having all of its limitations and only 1.5X the battery life, why would anybody bother? Reply
