OnePlus 5T battery life test results: excellent performer

The OnePlus 5T is one of the best phones you can buy for $500: the phone feels like a much more expensive device, has a sleek design and super fast performance, but what about its battery life?

We have used the OnePlus 5T for a couple of weeks now and we have also run our proprietary battery test, so we have a more complete understanding of its battery life.

First, let's get the specs out of the way, though. The OnePlus 5T features a 3,300 mAh battery, the same size as in the OnePlus 5. Despite its bigger display, we found that the new OnePlus 5T battery lasts about as long as on the OnePlus 5, which itself was an above average performer.

In practical terms, we get around a solid day, up to a day and a half of use on a single charge.

On our battery test, the OnePlus 5T scored 8 hours and 51 minutes, slightly better than comparable phones with OLED screens like the Galaxy Note 8 and on par with the Google Pixel 2 XL. Its score is about 5% lower than that of the OnePlus 5. Take a look at how it compares to other phones as well:

Battery life (hours) Higher is better
OnePlus 5T 8h 51 min (Good)
OnePlus 5 9h 18 min (Good)
Huawei Mate 10 Pro 12h 5 min (Excellent)
Apple iPhone X 8h 41 min (Good)
Apple iPhone 8 Plus 10h 35 min (Excellent)
Apple iPhone 8 8h 37 min (Good)
Samsung Galaxy Note 8 7h 50 min (Average)
Samsung Galaxy S8 8h 22 min (Average)
Google Pixel 2 XL 8h 57 min (Good)
Google Pixel 2 8h 40 min (Good)
LG V30 9h 34 min (Good)

What we love about the OnePlus 5T is its support for Dash Charge.

Dash Charge works in a different way than other fast charging solutions: it uses a higher amperage to achieve higher power deliver, while other fast chargers increase the voltage. The Dash Charge charging piece charges at 5 volts and 4 amps. What's particularly impressive about it is that unlike others, it will fast-charge the phone even when you are using it. We also love that with Dash Charge you don't need to leave your phone charging overnight because it is just so fast. Here are the charge rates:

  • at 15 minutes - 31%
  • at 30 minutes - 59%
  • at 40 minutes - 75%
  • at 1 hour - 91%
  • starts slower charging after it reaches around 75% charge, even slower after 90%
  • full charge takes 1 hour and 43 minutes

Charging time (minutes) Lower is better
OnePlus 5T 93
OnePlus 5 99
Huawei Mate 10 Pro 102
Apple iPhone X 189
Apple iPhone 8 Plus 178
Apple iPhone 8 148
Samsung Galaxy Note 8 102
Samsung Galaxy S8 100
Google Pixel 2 XL 152
Google Pixel 2 111
LG V30 108

Overall, the OnePlus 5T is a very good phone both in terms of battery life and in terms of how fast it charges.

Weaker than One Plus 5 in both cases. Makes perfect sense for a phone using only an elongated screen than OPO5 and remaining the same in every other aspect. But if you were to believe the test done by kids on youtube you would think One plus 5t is some kind of monster beating all phones by a huge margin. something really fishy.

Well, hard to argue with the many videos showing side by side comparisons and the 5T seems to last longer. But, PA never shows their actual tests.

Their OLED display phones seem to score lower than their LCD counterparts. Are you displaying a lot of pure white content or content with extremely high APL % with your testing methodology? A lot of side by side benchmarks between OLEDs and current gen best LCDs (iPhone 8/8 Plus) show more of the top rate OLED phones benching on top.

Actually a lot of the real world tests show that the 5T actually lasts longer than the 5. There are many videos on YouTube that show it. Still not sure how PhoneArena comes up with some of their testing.

Hello PA, full charge takes 1 hour and 43 minutes = 103 minutes NOT 93
