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.

Battery life (hours) Higher is better
LG V20 6h 23 min (Average)
Apple iPhone 7 Plus 9h 5 min (Excellent)
Google Pixel XL 7h 19 min (Good)
OnePlus 3 5h 53 min (Average)
Charging time (minutes) Lower is better
LG V20 86
Apple iPhone 7 Plus 197
Google Pixel XL 118
OnePlus 3 74


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.


  • Fast and fluid system performance
  • Secondary screen has great potential
  • 64GB storage as standard
  • Fast charging
  • Great image quality
  • Highly customizable UI
  • High-fidelity audio recording capabilities
  • Excellent sound quality during phone calls


  • Not the prettiest phone out there
  • Battery life is average at best
  • Fingerprint lock experience could be improved

O i forgot this is not an iphone. 8? I would give this phone a 9. LG ux is one of the best. You can make the phone feel unique to your style,personalize almost every thing,plus fast,smooth, and feature packed. Iphone has no headphone jack,limited customization,no sd card,only 1080p screen and it was rated 9.

They gave 9 to Pixel. Butthurt much? LG cant make a top of the top phone. They stopped making top phones since legendary G2.

You sound like a butthurt user who happen to get a raw deal with some LG phone in the past. Let it go. I know many girls who have told me they miss their LG phones, after having to get Samsung and HTC replacements. Everyone has their own preferences. Deal with it and so trying to bomb on LG.

Hello PhoneArena- you dont have to reduce the ratings because V20 may not sell like Apple or Samsung flagships. Just rate based on what it's worth.

They have to post a review which most of the readers here will like. Samsung and Apple has a huge following compared to other brands. There are more Apple and Samsung fans, now if they give the iPhone 7 a seven score, more people will be pissed.

What? Check the specs. Better camera, processor, UI, faster charge time, better stylus, wireless charging integrated instead of having to get a Qi sticker, and the design of having a flat screen is far superior to the Note 7. So, how is it the same device as a Note 4?

When was the last time an LG phone had THE BEST of more than 1 main feature of a phone? Best camera? Almost never. Best screen? Never. Best battery life? LOL, not since G2. Water resistance? Nope. Best speakers? Never. The only "BEST" feature this thing has its probably best audio quality output through headphones. Thats just one "BEST" feature. And you expect this thing to get a 9? Oh yes it has removable battery, yep and nowadays that's only a feature a tech geek will want.No Android phone will beat S7 edge and Pixel for 2016. Simple as that.

While I would not own a LG since I've had the boot loop with a G5, LG has been a top two in the camera department since the g4

Maybe they solved the boot loop problem this time.

So a worthless iCrap 6s got 9.3 while this phone just 8? Surprised? iPhoneArena does that on purpose. Put the st*pid Cr@pple logo on this LG phone and iTards will be drooling all over it.

I come here just for the news, while most of the news are not worthy of reading, they still have updated news. The reviews, on the other hand, are s**tty, those who review stuff don't know their stuff. I have to look for a review, I will go to PocketNow, Michael Fisher, and Android Authority (Android Authority does not review Apple but their reviews of Android phones are the most sensible.)

This is complete BS! Unacceptable! PA gives their useless ratings based on brands and not on what the phone actually deserves. Just because samsung and apple has has a huge fanbase and their fans would speak out, they get 9

Let's be honest, this was never gonna be a great phone.

The score seems fair if the software issues experienced are a common theme. The basic user experience of the device should be one of the big things a company nails right off. A device with this price tag needs to offer a stellar user experience. All the specs in the world won't matter if your experience is crappy.

woooooooow.... 1st, the battery life thing is bullsh*t.. i received the phone tuesday and have since then been testing "real life" useage. this battery kicks ass. idle over night (6hr) only lost 2%. heavy usage lasted me a full day (4am-10pm) with 7% left. the next with normal usage and auto brightness left me with 0ver 60%.. unless i got super lucky, this battery kicks a** in the last 6 mo. i tried s6/s7/s7E/N7/G5/V10.. V20 is beast

This is what i am looking for. The real use review. People do all sort of idiotic test which we dont even use it in real life and brainwash fans with these battery test. I was thinging of getting V20 for myself, was looking for a user review and you nailed it. Thanks

i was a huge PA fan until i saw this douchebag's biased rating.


Posts: 7; Member since: Nov 15, 2015

Iphone arena does it bias much?? Overkill for giving the public a very sophisticated phone?

If you love the phone so much why do you need a website to justify your purchase? Would a 10 out 10 make you feel better?

Trust me I'm getting mine regardless. They pulled this same crap with the V10 and that was such a great device.

CDM, it's not about being in love with this phone or any other phone. It's about giving the readers a bias opinion about a phone regardless of who makes it. PA is know for grading Samsung and Apple phones over their true values. Remember the S4 and S5 reviews? Both also got over a 9 rating but the S5 was a huge disappointment for Samsung and resulting in mass changes in the mobile department. Now LG V10 gets a 7 and LG V20 gets an 8.But when you read reviews from users and other sites on both you can easily see the bias.
