LG V20 battery life test results are out: here's how it compares against Apple's iPhone 7 Plus and Samsung's Galaxy S7 Edge


If you're looking for a big phone that provides all that you expect in a flagship, plus something more in the form of excellent audio and video capabilities, and a very neat small secondary screen for quick shortcuts, the LG V20 should probably be on your shortlist.

The 5.7-inch phablet by LG has just recently gone on sale in the United States, and it features a premium metal construction without stepping down from the core values of LG's high-end devices: an easily removable battery and a microSD memory expansion slot.

However, what about its battery life?

This has been a sour point of most high-end LG devices in recent years, and this time around the company says that it has taken into account customers needs and wants, and includes a larger battery in the V20. But larger in this case means larger than the LG V10's 3,000 mAh battery, which scored rather averagely on our test last year.

This year, we have a 3,200 mAh removable battery on the LG V20 and it scored a better result than its V10 predecessor, but its battery life still falls behind competing phablets from Samsung and Apple. In our test that puts all devices on equal grounds by setting their screens at the same 200-nit brightness level, the LG V20 scored 6 hours and 23 minutes of screen-on time, while Samsung's Galaxy S7 Edge had 7 hours and 18 minutes on the same test, and the iPhone 7 Plus aced it with a score of 9 hours and 5 minutes. The LG's score is not bad per se: it's on the same level as the Nexus 6P, but it's not outstanding by any means.


And what about charging times? Apple's iPhone 7 Plus might have excellent battery life, but it takes an eternity to recharge fully: it takes 3 hours and 18 minutes to get it from 0 to 100%. Luckily, the LG V20 does support Fast Charging and it was among the fastest charging phones out there: it took 1 hour and 26 minutes to fully recharge its battery, more than twice as fast as the iPhone 7 Plus. The magic happens thanks to LG V10's built-in 16-watt (9 volt, 1.8-amp) wall charger. It's worth noting that the V20 charges faster in the beginning, while the last few percentage points until the battery is fully recharged take much longer to charge because of the specifics of battery chemistry.

What does Typ 3200 mAh/12.3Wh Min 3080 mAh/11.9Wh Mean?

Typical battery capacity (3200mAh) and minimal possible capacity (3080mAh). It's similar to "silicon lottery" with CPUs and GPUs. Every battery won't be created equal, no matter how hard they try. This is printed on pretty much any battery just that you don't see it due to batteries being sealed.

First rule of the internet: Always assume it's a dude. No problem. I only knew about that because I saw it on G5's battery few days ago.

It doesn't really surprise me LG couldn't attain.a high score, as on GSMarena it only got 63hrs of battery life compared to the G5s 60. OLED needs to be adopted.

PhoneArea battery life tests are flawed. Just look at their ratings for S7 Edge and see the s**t what they have rated. GSMArena gives proper details are results they give are consistent with some other publications also.

Well said. The Note 5's battery still beats all of these phones...and it's a year old. LOL

Gsmarena battery life test is equally flawed like phonearena. For example read the test of nexus 5x . It says" The LG Nexus 5X is good for about two and a half days of moderate use, but with heavy use it will get you to the end of the second day. " I have used nexus 5x for 3 months and never i could get more than 24 hrs on moderate usage. I do no play any games. Even then it was pathetic. The only way you can actually get the idea of battery life is by using the device itself.

iPhone 7 plus takes more than 4 hours to charge ( 0 to 100%) and give only 7 hours of video playback.... While S7 edge takes 1.5 hours to charge completely to give 20 hours to video playback ..... iPhonearena called it iPhone 7 battery "Excellent" and S7 edge "GOOD"http://www.gsmarena.com/battery-test.php3?idPhone=7945#show

My 7 plus takes no wheres near 4 hours to charge and my S7 Edge battery life is good but not close to the 7 plus. The Note 7 was about halfway beteen the two.

That's funny, cause my s7 edge battery life is a lot better than my 7 plus. I can get 24 hrs easily while my iohone can barely make 19hrs.

It doesn't take 4 hours lol! I don't know where they got that from. It's more like 2 and a half hours. Now my iPad Pro 12.9 takes every bit of 4 hours to charge.

All these battery test are flawed. Load up all these phone with the 10 ten apps...Facebook, twitter etc...Let the phones do their thing, no Greenify, no restrict data background etc...and that's why I left Android for good.

You have a point but some phones are better than others.

I have 73 apps on my M8, it still gives me the same endurance it gave me a couple of months ago, 6.5 hrs max screen on time and 4 hours over the course of 24 hrs at 60% brightness avg.

Wait ... you actually think you can get 20h of screen on time out of a S7 edge ? AHAHHAHAHAHA

Really ? "In our video playback test we measure how long it takes for a device to run its fully charged battery down to 10%, while looping a standard-definition video. We stop at 10% since most devices shut their video players at this point. The display is again set to 50%, and all radios on the device are switched off (Airplane mode)." If you really think you can pull 20h of video run time on a S7 Edge , be my guest , please do report back your valuable valuable findings. I swear , people who actually believe those battery tests from gsmfraud are a bunch of idiots.

Thats where it was copied from , i know the claim , i know the site , its wrong. Also , im an LG user , keep swinging , you might hit sometimes . Btw , this is the reason the "isheep" make fun of idiots like you.

That phone has zero apps installed on it when they test it. And their endurance ratings are comparable with PAs test. Just that they add standby to the mix which Phonearena doesn't.

Go again and check that list , check the ONLY phones with a rating 15h+ for video playback , check also , for your average the xperia z4 tablet , then comeback with a conclusion. Hint , its not even realistic.

Well it's a small improvement but I'll take it. Oh by the way the recharge time should be one minute since you just pop out that battery and place a fresh one in. Now let's see the Galaxy S7 Edge and iPhone 7 do that. You don't even need an outlet or wireless charging or anything. For average battery life I will happily accept that trade off.

Its the only saving grace with these LG models i guess , but its still way too low for my taste. I had to run around with multiple batteries with my G4 and every time we had an official Android upgrade the battery life would take another 10% decrease...

Or a 3500mah replaceable battery. that will be an android gamer's dream, buy 3 back-up batteries and you'll doing clash of clans for days.
