LG G7 ThinQ battery life test results

LG G7 ThinQ battery life test results
The G7 ThinQ is the latest and most powerful phone by LG and while we've already given you a first look at the device, there is one particular aspect of the phone that we want to explore in further detail: battery life!

The LG G7 ThinQ features a 3,000mAh battery, a bit smaller than the average size for a flagship Android phone, so we were curious whether LG did some clever optimization magic to make this battery last a long time. Keep in mind that LG uses a different display technology than most other phone makers: it uses an additional white sub-pixel to the standard red, green, and blue pixels in a display, to help it get a brighter and this might also aid for battery efficiency.

To understand all of this, we ran our proprietary battery life test on the LG G7 ThinQ and the results are now in.

***Update: It turns out thatthe LG G7 ThinQ unit that we have tested initially was not quite the very final version of the device that will be available for customers. We have now gotten hold of the final version of the device and we have re-done and double-checked all of our testing, including the battery life test. The results that you see in the table below are the final results for the official LG G7 version that is currently available in stores.***

The G7 ThinQ scored 6 hours and 32 minutes on our battery test, which is... well, below the average for a 2018 flagship phone. Not by a ton, but still noticeably below the average. You can see the results of other phones and compare yourselves right below.

In our real-life experience with the phone, we still could get a full day of use out of this battery without needing to charge up during the day. Of course, if that's a very long day and you get home late, you might need to charge up during that lunch break.

Battery life (hours) Higher is better
LG G7 ThinQ 6h 32 min (Average)
LG V30 9h 34 min (Good)
LG G6 6h 9 min (Poor)
Apple iPhone X 8h 41 min (Good)
Apple iPhone 8 8h 37 min (Good)
Apple iPhone 8 Plus 10h 35 min (Excellent)
Samsung Galaxy S9 7h 23 min (Average)
Samsung Galaxy S9+ 8h 5 min (Average)
Samsung Galaxy Note 8 7h 50 min (Average)
Google Pixel 2 8h 40 min (Good)
Google Pixel 2 XL 8h 57 min (Good)
OnePlus 5T 8h 51 min (Good)
Sony Xperia XZ2 8h 54 min (Good)

Another important aspect of the battery experience is the time it takes to charge a phone.

Luckily, the LG G7 ThinQ supports quick charging and using the wall charger that comes in the box, we measured that it takes 1 hour and 42 minutes to fully recharge its battery from 0 to 100%. This ranks the G7 as one of the fastest-charging phones, which partially offsets the middling battery life score.

It's worth knowing that LG's 2018 flagship also supports wireless charging via the Qi standard, so you can use various wireless chargers to juice it up. There is no wireless charger included in the box, though.

Charging time (minutes) Lower is better
LG G7 ThinQ 107
LG V30 108
LG G6 97
Apple iPhone X 189
Apple iPhone 8 148
Apple iPhone 8 Plus 178
Samsung Galaxy S9 107
Samsung Galaxy S9+ 105
Samsung Galaxy Note 8 102
Google Pixel 2 111
Google Pixel 2 XL 152
OnePlus 5T 93
Sony Xperia XZ2 145

How is 3 minutes less battery life than its chief competitor, the Galaxy S9 a fail?

S9 is a failure in itself.

what screen resolution did you use during the test? Can you test the phone with FHD+ resolution?

32. integrazimmy

Unfortunately, you can't change the resolution on LCDs, only on OLEDs. Which presents the following problem... How do we know what resolution The Galaxy S9 & S9+ were ran at since they come at 1080p FHD right out of the box, while the G7 comes with QHD+ fresh off the boat. If this is the case, then the test is flawed as it is not uniformal.

No. You can change the display resolution in LG G7. You can check the review 'LG G7- the phone i want to love' by Dave Lee in yotube at 2:27.

To push the manufacturer to do better next time ?

It's on par with the s9 and an 1hr and 11min more than the g6 so it's an improvement over the g6.

Everything about this phone is mediocre. It's neither big nor compact, neither thick nor thin, battery life neither bad nor good, camera neither great nor bad etc. Looks like creators of this phone have been trying to catch a little big of everything from everyone and as a result we have a device with no its own face which looks like mix of everything thus boring and unrecognizable.

Not bad, S9 5,8" and 3000mAh, G7 6,1" and 3000mAh.

But roughly the same screen area since the G7 has a taller aspect ratio and a notch.

7h 20 should by no means be rated as "good" when other phones can do so much more! I consider 7h 20 as bad!

So what you're saying is that the Galaxy S9 has crappy battery at 7h 23min????

41. Cat97

Posts: 2055; Member since: Mar 02, 2017

The S9 has notoriously bad battery life even compared to the S8, due to Samsung's new processor with customized ARM cores.

I've no idea why people are complaining about its battery life here? It's just 6 mins shy of my S6 which has a fantastic battery life. My S6 lasts me a whole day on just 40% battery as I religiously follow 40-80 rule* with a full charge / discharge once a month with air-plane mode enabled during my 6-8 hour sleep cycle. My cellular mode remain set on 3G (4G LTE is overrated!) with 2 hour E-Mail & Contacts sync cycle and Twitter, What'sApp push notifications enabled and a lightweight "Quick Note" app constantly running and syncing in the background all the time with everything else closed. Oh well, G'Day! *https://www.wirelessdesignmag.com/blog/2015/11/why-you-should-stop-fully-charging-your-smartphone-now

Lol, the crap battery life on s6 was the main reason i sold it, that and laggy ui after a while. The LG did ok this time but worst of all current flaship, and battery life is one area where ever minute counts. But you referring to s6 as great battery life is hilarious.. It's among the worst I've owned when it comes to Battery life.

Linus also make video about that (tl;dw he said the best is charge till 65% and use it till 50%, repeat) Personally, I just drop it in wireless charger whenever I don't use it, I charge 20%-80% if possible (accubattery can do reminder for that, and it's good at monitoring battery usage, charge rate and battery wear),

4G overrated? maybe in the US, in Europe 4G is a big leap forward compared to 3G

24. DFranch

Posts: 568; Member since: Apr 20, 2012

No, 3G is pretty much useless in the US too. I don't even bother trying to use anything requiring internet access if i'm on 3G. Fortunately, it isn't too often.

Can't call it "improved", since V30 with similar dimensions has larger battery and lasts much longer. G7 is a straight downgrade from V30.

LCD uses more space than oled

15. Pabliell

Posts: 189; Member since: Mar 22, 2016

So? They could stick to OLED then, make the battery bigger and make overall a better phone. They didn't. That's the point. They didn't make a better phone, even though they took their time and released it later than everyone else.

40. Cat97

Posts: 2055; Member since: Mar 02, 2017

Then why does the G6 have a 3300 mAh with LCD, while being smaller than G7 ?

17. TechNeck

Posts: 658; Member since: Aug 29, 2014

It's the successor to the G6, not the V30. It's not hard to put two and two together.

29. Pabliell

Posts: 189; Member since: Mar 22, 2016

True, but in terms of size G7 is much closer to V30 than G6. And the G7 didn't even get close to V30 in battery life.

34. integrazimmy

The size of the phone does not dictate Flagship class. It only dictates size. For that matter, why don't we compare The G7 to the Samsung Galaxy Grand Prime and call that Samsung Garbage???? They're both about the same size. Smh!

39. Pabliell

Posts: 189; Member since: Mar 22, 2016

G6 and V30 are flagships, Grand Prime was not. I compared flagships to flagships, you did not. Start thinking.
