OnePlus 6T battery life test results: one of the best battery performers of 2018

OnePlus 6T battery life test results: one of the best battery performers of 2018
The OnePlus 6T might be a gradual update over the OnePlus 6 as both phones share a similar design, but there are two key areas where the 6T innovates that are worth your attention: the first is the in-screen fingerprint scanner and the second is quite simply a bigger battery. And that's important.

The new OnePlus 6T comes with a 3,700mAh battery, the largest OnePlus has ever put in one of its phones and considerably bigger than the 3,400mAh cell used in the 6. So is there any big difference in battery life that you should care about?

To understand this, we turn to our proprietary battery life test and the results show that indeed there is.

Battery life (hours) Higher is better
OnePlus 6T 9h 52 min (Excellent)
OnePlus 6 8h 10 min (Excellent)
OnePlus 5T 8h 51 min (Excellent)
OnePlus 5 9h 18 min (Excellent)
Huawei Mate 20 14h 26 min (Excellent)
Apple iPhone XS Max 9h 34 min (Excellent)
Apple iPhone XS 8h 37 min (Excellent)
Apple iPhone XR 11h 1 min (Excellent)
Samsung Galaxy Note 9 8h 56 min (Excellent)
Samsung Galaxy S9+ 8h 5 min (Excellent)
Samsung Galaxy S9 7h 23 min (Good)
Google Pixel 3 XL 7h 39 min (Good)
LG V40 ThinQ 6h 21 min (Average)
LG G7 ThinQ 6h 32 min (Average)

The OnePlus 6T scores a very respectable 9 hours and 52 minutes, more than most flagships of 2018, and certainly one of the highest scores for a phone with an AMOLED screen.

This score beats the iPhone XS Max, the Samsung Galaxy Note 9 and the Pixel 3 XL, which is great news for those considering the 6T as their next flagship.

The two phones the 6T loses to in our battery test are the incredible Huawei Mate 20 (not the Pro, which has a more average battery life) and the iPhone XR, both devices with more power-efficient LCD screens.

The other part of the battery equation is the time it takes to fully recharge a phone from 0 to 100%. The OnePlus 6T comes with the signature OnePlus fast charger and the red USB-C cable in the box, so you don't need to pay extra for that (cough, Apple, cough).

Charging time (minutes) Lower is better
OnePlus 6T 85
OnePlus 6 80
OnePlus 5T 93
OnePlus 5 99
Huawei Mate 20 98
Apple iPhone XS Max 209
Apple iPhone XS 185
Apple iPhone XR 192
Samsung Galaxy Note 9 109
Samsung Galaxy S9+ 105
Samsung Galaxy S9 107
Google Pixel 3 XL 123
LG V40 ThinQ 109
LG G7 ThinQ 107

In the charge test, we see that the OnePlus 6T again excels and recharge in no time. It took it just an hour and 25 minutes to reach a full charge, meaning that you could forget to charge the phone overnight and still plug it in for a few minutes in the lunch break, and you will still get enough juice to get through the day. So this makes the OnePlus 6T one of the best phones in 2018 in terms of battery life and marks the excellent work from the OnePlus team on optimizing battery performance.

Meanwhile, we are actively working on our detailed OnePlus 6T review. Stay tuned for that, it's coming up soon!

I am still yet to find out how your'll carry out this bogus battery life test which doesn't coincide with the results of any other website...gsmarena does way better job.

PA's tests seem to favour the iPhones too much sometimes.

It's not that. After seeing these results, it seems like: 1. These tests favour LCD screens a lot more than OLEDs. Probably they are static text, or slowly refreshing text which leverages the panel self-refresh in LCD screens. 2. They are really, really SoC focused tests, and your processor matters a lot more than it does in real life. You can literally see that devices with same SoC are really bundled together. And it's not that it favors more efficient SoCs. SD845 is more efficient than 835, yet 845 devices get worse battery life. 3. They don't mirror real life that often, and often contradict with other sites even. Moreover, the opaque nature of them not revealing how they test definitely doesn't help. I don't think they favour iPhones, but the characteristics iPhones have get boosted by these tests. For example, check out the Huawei mate 20 above, since it's the most 'iPhone-ish' phone out there with a 7nm chip and low-res LCD screen.

Huawei Mate 20 is the most iPhone-ish? these tests favour phones with best battery life and who cares is it LCD or OLED?

Based on the test, you can easily make it biased towards LCD or OLED phones. Low-medium APL, plus screen refreshing all the time (video, scrolling etc): OLED phones will destroy LCD ones. Most youtube battery test are these kinds. High-100% APL, mostly static content on screens: LCD easily win.

If that were true they'd jibe with every other battery test on other sites. They never do, they're always in contradiction.

It's not just PA's tests where they favour iPhones. The majority of their articles they favour iOS over Android devices

No it’s not that. It’s you that are so biased and you are projecting. To me it seems at most each author has a preference but they seem to go to far out of there way to try and cater to the idiots in the comment section. If I were them I would not even read the comments. Nothing but bitching no matter what they say

All the tests online on YouTube showed that both iPhone xs and xr died first, and the XR had the worst battery among these phones. I'm taking about different YouTube channels, how the hell do you people do your tests

BS, then you have not watch any. There are many tests they perform really well beating out all (XS max) or close to. Here is two them but there are more if you do a search for battery tests. ”” and ””

Nonsense? Did you watch the videos? The statement that iPhone always end up last in all youtube tests are clearly not true.

34. TheOracle1

I don't need to because empirical evidence shows that iPhone's are always at or near the bottom of every credible list. I'll take GSMArena numbers over any other tests including YouTube videos, because they also test talk time amongst others which is how a phone is supposed to be tested. Good luck and dream on buddy.

Haha, are you kidding?! You don't need to see? Talk about being biased :D I give you proof that what IT-Engineer says is not true what so ever but you do not need to see the proof because you "know" it incorrect. That is funny! You put your faith in a site that long after pretty much all other serious tech sites started using fixed nits values for their battery test still was using % of screen brightness (in other words put the phones with bright screens in a bad position)... Fact is that many tests shows similar results to what phonearena gets (if you actually care to look at other than GSMArena). The reason you will see different result in different test is because of how the tests are made, what kind of workload they put on the phones.

I think I've figured out PA's voodoo battery tests. They say they run a custom web script on the phone until it dies. No problem there and iPhone's do well in that category. When you compare their numbers to the web browsing numbers of GSMArena they're more or less similar. BUT GSMArena also test talk time (as they must do since it's a darn phone to begin with) and video playback. In those two categories the iPhone is lame. GSMArena average everything and come up with a number. So basically PA doesn't really test every aspect of the phones. In fact their testing is woefully incomplete and frankly useless. IPhone XR: talktime 15:03, web browsing 13:04, video playback 15:08 OnePlus 6T: talktime 29:08, web browsing 12:04, video playback 15:40 In fact the XR has one of the worst talk time numbers on the entire GSMArena chart for current phones. In conclusion, so long as you don't make any phone calls (ironically on a device called the iPhone and designed for that purpose) you'll be fine!

Well you kinda answer the question behind the good scores of iPhones yourself. PA runs a custom web script. What do the iPhones do very efficiently? Run web scripts. Much more so than any Android phone comparatively. That's why their battery life test results differ so much from real life situations. I won't go as far as saying it's purposely set up in this way, but they should be well aware that it's not a good, reliable way of testing which accurately reflects real life usage.

Differ from real life? Do you actually think the workload of a phone is the same for all people? I could not care less about talk time since talking on it is the least thing I do on my "phone" today. Some will use it alot for talking, some will not use it at all (like me). Some will play heavy games and some will just use fb, instagram and so on. How a phone do in real life depends on how you use it.

That's like testing the AC on a car and concluding it gets great gas mileage. Retarded.

What are you talking about? Do you not realize that people use their phone differently? Get out of your bubble...

47. TheOracle1

Posts: 2340; Member since: May 04, 2015

That's my point Einstein. A battery test should be comprehensive and test every aspect of a phone. If it only tests web browsing and I use it for phone calls (imagine using a phone for phone calls!?) then the testing method is useless. You're not very smart are you?

48. c.m.s

Posts: 239; Member since: Dec 10, 2017

No, you do not get it. Me and alot of other do not care for talk time at all. Its not a real world test to include talk time when testing for how long the battery will last for me since I do not talk in my phone. The youtube tests with movies, games and web browsing is a much more true to life test in my case. For you it can be a completely different scenario, that is my point.

I really feel for your type of stupidity. It's a phone with various capabilities and used in multiple ways by every buyer. Simple logic dictates that any test (battery or otherwise) would try to give a potential buyer an indication of how the phone will perform for their unique use. It seems that concept is beyond your pea brain. If X uses a phone for videos, Y uses a phone for browsing, Z uses it for phone calls, T uses it for gaming P uses it for music and Q uses it for gps/commuting; wouldn't you like to know how that phone performs for your particular use? I own a NexS and I'm in a different battery division to what we're discussing. But then again, that's why I own a NexS. The battery life crushes every flagship for 2018 whilst being f*cking cool. Go check YouTube if you don't believe me. Dream on!

Personal attack when lacking arguments, surprising. And you are saying the exact same thing as I am trying to get through to you. A user like me is not interested in a test of talk time. For _me_ its completely useless since I do not use it that way. There is nothing wrong with either battery test, they are just testing different things (which is good) because we all use out phones differently. And what started this discussion was the statement that iPhone always ended up last in youtube battery test which I already showed is completely incorrect. It’s a fact, like it or not...

Like saying a car gets great gas mileage because the AC is excellent. You haven't tested the WHOLE car you moron.

Is it really that hard to understand? It does not matter if a phone get a high general score in GSMArenas battery test if i’m not using my phone for making calls and its that call test that brings down the score. Its not a number true to life and completely irrelevant to me. If you are another type of user that call test can be important to you. It’s not the same for every user.

55. TheOracle1

You are truly thick. The tests are not for you or me alone, that's why it's important to test every aspect of the phone. So it will give EVERY potential user an idea of it's strengths and weaknesses. All this seems to be lost in translation for you because I'm beginning to think that English isn't your first language.

Haha! Why would I care for something that is not relevant for me?! There are tons of battery test, all testing different things. Pick the ones that is relevant to you instead of pointing to _one_single_test_ that base the total battery score on something alot of people do not use it for. I can compare the web/video part of the test but the general score is completely irrelevant. Try to understand, there is no ”right” battery test, it all depends on how you use your phone, therefor look at those relevant to you not what is good for someone else! Simple as that. GSMArena is _not_ any better than phonearenas, anandtech or some of the youtube ones.
