LG V20 Review

LG V20

Battery life

The V20 leaves us wanting more out of its battery life, but we can’t complain about charging speeds.

While the LG V20 is an overall great phone, its battery life leaves something to be desired. Equipped with a 3200mAh battery, it is an average performer – both in our custom battery benchmark and in real life. The rating we measured stands at 6 hours and 23 minutes, which puts the phone behind the Galaxy S7 edge and iPhone 7, but ahead of the OnePlus 3 and last year’s V10.

In my experience, the LG V20 lasts a full day on a single charge if used with moderation, and I’ve managed to stretch that into the second day on several occasions. However, heavy use will have its battery drained by early evening. As expected, gaming sessions and camera use take a serious toll on its battery. In contrast, stand-by times are actually pretty good. If I forget to charge it overnight, the phone loses around 5-6 percent of charge, which is surprisingly low for an Android phone.

On the bright side of things, the V20 is really quick to recharge thanks to its bundled QuickCharge 3.0 charger. It requires 86 minutes to go from zero to full, which may not be record-setting, but it is pretty fast nonetheless. Furthermore, it takes just 30 minutes to charge from 15 to 65 percent, meaning that if it stays plugged in while I get ready for work in the morning, I’ll have enough charge to last me through the day.

I must also reiterate that the V20 has a removable battery – a feature becoming increasingly rare among high-end phones. What this means is that you can swap an empty battery for a full one if the circumstances require it. However, purchasing a second battery for your V20 may set you back around $40, so it is your call whether that’s worth it or not.


It is no easy task to describe what being an LG V20 user feels like, but to wrap things up, I’d say that it is quite an adventure. At first, there’s the euphoria of owning a phone so technically advanced – both in terms of hardware and software capabilities. Then comes the confidence you get, knowing that your phone is designed to be durable and reliable. And there’s something strangely satisfying when your phone draws others’ attention. “Wow, what phone is that?”, people often asked me; then I got to show off the V20’s unique camera setup and to brag about its actually useful secondary display.

Eventually, the frustration of having to adjust to the LG V20’s quirks settles in. There’s the inefficient fingerprint reader experience, the impractical display of notifications on the secondary screen, and the limited and often unusable dual-screen mode, to give a few examples. Later on, you realize that while its technical capabilities are awe-inspiring, they’re not something the average user would ever need. Seriously, manual video controls and Hi-Fi sound recording are overkill for a phone!

But you know what, that’s the whole point! The LG V20 is not really a mainstream device. It is built for power users, camera fanatics, audio enthusiasts, and content creators – for the mobile gamer, for the adventurous photographer, for the guy and his band in his garage, or for the hyped young YouTuber who just got his first 1000 subscribers. They’re the ones who would appreciate the full package of features that the V20 has to offer.

At the end of the day, if all you need is a good phone that just works, the LG V20 probably isn’t the best option for you. But if you see yourself as a geek, as a technology fan who knows how to make the most of a phone like this, I’d recommend giving it a try.
