OnePlus 6 battery life test results: above average

OnePlus 6 battery life test results: above average
The newest OnePlus 6 has just gone through our proprietary battery life test and the results are in.

We have been using the new OnePlus 6 for more than two weeks now and it has all been a breeze as the phone gets us through a full day with ease, but to get a true understanding of its battery life we had to compare it on equal terms with other devices.

The OnePlus 6 features a 3,300 mAh battery and the latest Snapdragon 845 system chip on board. While the chip is new, the battery is the same size that we have seen in the OnePlus 5 and OnePlus 5T. With a few extra pixels from the slightly larger screen, though, we were curious to see how the phone performs.

Interestingly, the OnePlus 6 battery life score is lower than that of the earlier OnePlus 5 and 5T. The 6 scored 8 hours and 10 minutes on our battery test, while the 5T result was some 40 minutes higher and the 5 result was even higher, lasting an hour and some 20 minutes longer.

Battery life (hours) Higher is better
OnePlus 6 8h 10 min (Excellent)
OnePlus 5T 8h 51 min (Excellent)
OnePlus 5 9h 18 min (Excellent)
Apple iPhone X 8h 41 min (Excellent)
Apple iPhone 8 Plus 10h 35 min (Excellent)
Samsung Galaxy S9+ 8h 5 min (Excellent)
Samsung Galaxy S9 7h 23 min (Good)
Google Pixel 2 XL 8h 57 min (Excellent)
LG V30 9h 34 min (Excellent)
Xiaomi Mi Mix 2s 7h 57 min (Good)

You can clearly see that the OnePlus 6 is slightly above the average for a flagship phone, but while other phones have improved their showing, the 6 seems to last slightly less than its predecessors.

Record charging times


Another important aspect of the battery experience is the time it takes to recharge your phone.

While the OnePlus 6 does not support nice modern conveniences like wireless charging, it comes with the well-loved Dash Charge feature. OnePlus seems to have some issues trademarking it, so it refers to the feature as simply fast charging now, but the Dash branding remains present on the cable, so for simplicity sake we'll just refer to it by its old name.

Dash Charge promises of delivering "a day's power in half an hour" and it lives up to that promise. Not just that, in our testing, it took just 1 hour and 20 minutes to get a full charge, from 0 to 100%, the best result from any phone.

Charging time (minutes) Lower is better
OnePlus 6 80
OnePlus 5T 93
OnePlus 5 99
Apple iPhone X 189
Apple iPhone 8 Plus 178
Samsung Galaxy S9+ 105
Samsung Galaxy S9 107
Google Pixel 2 XL 152
LG V30 108

So while the OnePlus 6 is not quite the phone with best battery life out there, we found that it easily gets us through a full day of use and that its fast charging is not merely fast, it's the quickest that we have ever tested in the past couple of years. Good job, OnePlus!

Maybe all the people moaning about the OnePlus 6 "small" battery might just shut up now.

Why would they when the battery life is worse than its predecessor? Compare with the flagship battery life of the mate 10 pro with over 12hr.

It's about on par with other big screened flagships (S9+, pixel 2 XL). I guess that's fine, though I was expecting better. They stuck with the smaller battery since they thought that the lower res screen will take them through.

The charging time has been lessened big time!

Charging is like a proctology exam, the quicker the better, but also, the less often it's necessary, the better.

3300mAh and FHD+ 8h:10m, OK LG G7 3000mAh and QHD+ 7:20. But LG Settings HD or FHD or QHD resolution!

can't be so effective . because by Settings to HD or Full HD , useless pixels won't be turned off . ( because of cheap LCD display :| ) just compare V30 battery and G7 , u will find why lg did this wrong ...

Interesting...OnePlus 5 has extra 1 hr of battery life than 6. I am sure it’s considered improvement at OnePlus HQ.

6.3" vs 5.5" . 1+6 results are good.

Wrong, LG G5 seems to have the fastest charging time of 76 minutes. How could PhoneArena forget its own result??

You want them to include a 3 year old phone? Why don't they just include an old flip phone, I'm sure those charge their 100mAh batteries in a few minutes. (sorry, just being snarky)

As far as smartphones are concerned, LG G5 shows the best results. So why mislead people? Even if it's just a 4 mins diff. and the G5 is 3 year old. That's my point.

It's 3 years old and has a small battery...of course it will charge faster with quick charge tech. All the phones mentioned are released after 2017. Relax.

u forgot V10 to ( 65 min ) and my Galaxy S II can be fully charged in 3 mins ( because of spoiled battery ). , 5 % in 2s sometimes it starts to charging without plugging to charger. lol
