OnePlus 3 battery life test results are out, we also examine Dash charge claims

The OnePlus 3 has just made it through our battery life test and the verdict is in.

But first, let's take a look at what we're dealing with here: the OnePlus 3 features a 3,000mAh battery that powers a 5.5" handset running the Snapdragon 820 system chip. It's also notable that the OnePlus 3 has a 1080 x 1920-pixel AMOLED display, a lower resolution than most current, Quad HD flagships and that is supposed to have a positive effect on battery longevity.

We also ought to say that we test the battery life of all phones using the same script that puts devices through a typical usage routine and all displays are set to a brightness level of 200 nits, a level comfortable for indoor use. Throughout the runtime of the test, the display stays on all the time, so stand-by time is not accounted for here.

With this in mind here is the actual OnePlus 3 battery life test score: 5 hours and 53 minutes. That's how much the phone lasted on our test, and that puts it among the worst performers this year, on par with the rather poorly performing LG G5. And that's quite the disappointment. Yes, with moderate use the OnePlus 3 should be able to last a whole day, but we still find it odd that the new OnePlus 3 actually has a slightly, but noticeably lower battery life than its predecessor, the OnePlus 2.

Devices of similar physical size from mainstream manufacturers like the Apple iPhone 6s and Samsung Galaxy S7 Edge perform much better, delivering much more solid battery life.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

hours Higher is better
OnePlus 3
5h 53 min (Average)
Samsung Galaxy S7
6h 37 min (Average)
Samsung Galaxy S7 edge
7h 18 min (Good)
Apple iPhone 6s
8h 15 min (Excellent)
Apple iPhone 6s Plus
9h 11 min (Excellent)
5h 51 min (Average)
HTC 10
7h 10 min (Good)
OnePlus 2
6h 38 min (Average)
Sony Xperia X
8h 56 min (Excellent)
Xiaomi Mi 5
7h 27 min (Good)
Honor 5X
6h 54 min (Average)

While that's a disappointment, we were not at all disappointed by the new Dash charge technology used in the OnePlus 3. OnePlus says that it only works with a OnePlus wall charger and a OnePlus cable (which is annoying, but probably not a huge problem for many people), and it lives up to the promise: it recharges the OnePlus 3 from 0% to 63% in half an hour, exactly as promised by the company.

Here are the charge times that we recorded:

  • in 15 minutes, we got 19% of charge replenished (from 0%)
  • in 30 minutes, we got up to 63%
  • in 1 hour the phone was almost fully charged at 96%
  • the full, 100% charge took just 1 hours 13 minutes
This makes the phone an absolute champ in terms of battery recharge times. It is in fact a bit faster than the LG G5, and in the same vicinity as phones from Oppo that also feature a similar charging solution.

minutes Lower is better
OnePlus 3
Samsung Galaxy S7
Samsung Galaxy S7 edge
Apple iPhone 6s
Apple iPhone 6s Plus
HTC 10
OnePlus 2
Sony Xperia X
Xiaomi Mi 5
Honor 5X

All in all, the battery life of the OnePlus 3 is definitely a mixed bag. We really wish the phone lasted a bit longer, but it's quite obvious that under heavy use, you might need to charge it up before the end of the day to have a peace of mind.

damn that iphone 6s+ is killer in battery life but garbage in recharge time. ALMOST 3 HOURS. DAFUK op3 45 minutes less use from op2. meh. make the freakin thing a bit thicker and get the fuckkin ugly camera bump flush. sheesh. when they were in the final meet and they were passing around the prototype to everyone, and the big douche says "ok, were sending this phone to production:, did no one raise their hand and say, "DUDE, wtf with that ugly ass camera hump?" ? did they all nod and say good to go! ? I think mfr need to do all 3 things. bigger battery for better use time, also offer removable battery and have quick charging function. but id take swappable battery anytime. its only a minute to go from 0 to 100% I love my G4. ok/decent battery (does better than the op3) but I have one extra slim battery in my pocket and dont need to rely on carrying a charger/cable or to be tied to a power outlet. I swap and in 1 minute im up to 100%. no charger does that.

The battery life increases in ca. two weeks. Slightly, but still. It also gets more constant and stable. Really, measuring battery after first day or so, will provide inaccurate information. I am using the OP3 since Thursdag and the battery life is quite well for a battery with 3000mAh capacity.

I purchased my first OnePlus product and am already questioning why I pay $200 to $500 more for the big brand smartphones. The OnePlus 3 may change my future purchase plans. Check out 10 reasons to choose OnePlus 3 over a Samsung, LG, HTC, or iPhone

whoever is considering an iphone or samsung is not considering a oneplus 3. forget that. but those who are considering the op3 are looking at other products within the same price range. moto x style LG g4 meizu or xiaomi mi5 are ones that are better than the op3. the phone has hype written all over it. they passed a lot of phones all around for free for positive reviews, but wait till the hype passes in 3 months and see the sales are crap. its a phone that hype build but there is no substance.

actually i6s+ still far from the top battery life's rank and S7edge and Mi5 should be above i6s+ (according to other sites)


Posts: 107; Member since: Apr 15, 2016

of course, but it's only 2750mAh. it could compete with 3000mAh found in Note 5. almost doubling LG G5, which is impressive, it's still a last year flagship.

I still can't get over the fact PA claims the iPhone 6S+ and the Note 5, both lasted the exact same amount of time. It is mathematically impossible, because the Note has a larger battery and more feature. But the iPhone having 1/2 the hardware prowness, I think it should have lasted longer. 13hrs is what I saw the Note 5 have at the highest and that's video playback with the screen always on. Not sure how PA measured. But the One Plus is doing good for $400. It seems to be nice, but I want features.

Agree so let's make a new criteria : Battery performance= battery life - charging time

Maybe optimizing is one of the things they have to cut off just sell it on an affordable price. And I'd rather have a phone with long endurance and long recharging time than a fast charger that quickly dies. LBS made a youtube battery endurance test between lg g5, htc 10, huawei p9, and vivo x elite. Watch it guys to know who got into 2nd place.

Wow that battery life sucks, even with the limit they set on open apps (so it will never use that 6GB anyway)

The battery life doesn't suck as much as PA makes it seem but it isn't much better tho lol. this is a more thorough battery test.

It's probably the software running the phone: OxygenOS 3.1 Judging by OnePlus' track record, the battery life will improve in the next six months.

Very strange outcome, they have a FHD vs Samsung a QHD screen. I wonder why the poor result for OnePlus 3.

Samsung is pretty much a undisputed champion when it comes to Amoled displays on phones. You can bet Samsung is using the most advanced display which is probably very battery efficient inspite of its higher resolution unlike what One Plus 3 might use.

Samsung is one of the best manufacturers when it comes to optimizing its hardware. Anyone who says TouchWiz is unoptimized crap is probably blind.

I don't know but with my usage I think s7 edge lasts longer than my iPhone 6 on daily usage basis. But if I see standby time that's more on iPhone 6s. That's just on basis of my usage so that might not be same for you.

A lot people hare touchwiz but you can't deny how optimized it is.

I wonder if PA uses a lot of white colors in the testing which causes the OLED based devices to be on full pixel. PA is the only one that said S7/S7E pair to have bad battery life out of all the other tests done by anyone else

Without revealing too much detail, let's say that we do indeed use whites, but that is also a quite typical color in the most common applications on current smartphones, so it seems well justified. The browser, the dialer, mail, calendar, Google Now, and many others use a lot of white color, and users spend most of their time in those apps.

'Without revealing too much details' - Instead, you guys should be very transparent when it comes to your testing methodology.

True, but methodology aside whats more important is consistency.

30. Victor.H

Our test (unlike some others that are often quoted ;)) has been perfectly consistent across all devices that we've tested from day one, and we've started making these tests way before Samsung was THAT huge, so arguments for bias towards one or other company are quite nonsensical. Anyway, do let me know if you have any particular questions about our battery testing and I'll see how we can answer them! We've been quite transparent with our testing method without releasing the full script for everyone to use.

Why not release the full script? That would offer true transparency into your testing process, and allow others to validate your findings.

What difference does it make if they're testing all devices the same way?

The results of battery tests at PA are routinely radically different than the results of other sites. It would be kind of nice to know why.

Here is a really good question. why push a phone brightness to 200 nits when companies design a screen to be optimized with the battery at certain brightness level. Its unfair because of tech behind the screens just because Super Amoled has a bighter screen doesn't mean LCD can Handle the same brightness level with out pulling more power.Need to be fair and run at a brightness percent than bhrightness nits.Once you do that then you can see how battery life preforms

56. Victor.H

Posts: 1062; Member since: May 27, 2011

Okay, good question! Now, imagine we did it your way, measuring brightness at 50%. On some LCD phones that would be 150 nits, on others - 200 nits. The latter one will automatically have a huge and unfair advantage. So how would this be a fair comparison then?

Without revealing to much detail ? That is exactly what someone with a biased benchmark would say. Since you are biased, nobody will believe your battery test especially when you put the iPhone 6s Plus, known as one of the smartphones with the most average battery life, as you did on the list (and no I am not an Apple hater, I have an iPhone myself).
