Razer Phone battery life test results: a bit short of the 2-day dream

The Razer Phone is a different phone: it is the first mainstream phone with a faster display, one with 120Hz refresh rate, a key asset for gamers, but how good is the Razer Phone as a daily driver?

To answer that question, you need to know how good is its battery life.

The Razer Phone ships with a 4,000 mAh battery on board, larger than most other top-end smartphones. While that's great, it is also needed: the faster display also draws more power, and considering that it is a phone for gamers, battery life is key.


We ran our proprietary battery life test on the Razer Phone and it scored 8 hours and 52 minutes, which is a very good result. Still, for those expecting wonders, the Razer Phone is not a record-breaker in terms of battery life. Keep in mind that we do our battery life test in equal conditions for all phones: we set brightness to the same level and turn off notifications. Also, we ran our tests at the Razer's default 90Hz screen setting. The phone's display can also be set to run at 60Hz or at 120Hz, with the lower refresh rate requiring less power, while the highest option allowing for the most clarity, but also requiring the most out of the battery. We will be running the test at the other settings in the near future to see how change the refresh rate affects battery performance.

Battery life (hours) Higher is better
Razer Phone 8h 52 min (Good)
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)
OnePlus 5 9h 18 min (Good)
OnePlus 5T 8h 51 min (Good)
Huawei Mate 10 Pro 12h 5 min (Excellent)

In real life, we can get through a full day with the Razer Phone even if we spend a couple of hours playing games, which is nice. On those days when you don't play games, you can expect a day and a half, and with scarce use, you could even stretch that to a full two days, but that would really be a stretch.

Charge time test!

The Razer Phone is also the first phone to support Qualcomm's Quick Charge 4.0 standard. 

What does this mean?

Qualcomm's promise with Quick Charge 4.0 is that a device can go from an empty battery to 50% charge in just 15 minutes. Additionally, you have new technologies to extend battery cycle life, enhance safety, and expand charging intelligence. You can read the full Quick Charge 4.0 white paper on Qualcomm's official webpage here.

And while the Razer Phone comes with a Quick Charge 4.0 wall charger in the box and all the support needed for it, we don't see it living up to those promises. In fact, Razer makes a quite different promise: it actually says that it will reach a 50% charge in 40 minutes. That we found to be true.

Here is the charge rate for the Razer Phone:

  • at 15 minutes - 25% battery level
  • at 30 minutes - 37%
  • at 40 minutes - 47%
  • at 1 hour - 64%
  • starts slower charging after it reaches 90% charge
  • full charge takes 2 hours and 20 minutes

As to the charger itself, it's a 24-watt wall charger a USB Type-C port right on the charger, and you get a USB-C to USB-C cable in the box with the phone, just like with the Google Pixel devices.

Charging time (minutes) Lower is better
Razer Phone 140
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
OnePlus 5 99
OnePlus 5T 93
Huawei Mate 10 Pro 102

The Razer Phone does not support wireless charging, in case you were wondering.

Who knows. But the point was to compare to a bunch of other phones not necessarily all of them.

More than likely they haven't tested the phone yet.

We hope we can have it up soon.

These tests are always so weird and unreliable, especially considering in another article here it says: Battery life was found to be inferior to Samsung's latest flagships, though, and that is mostly why the iPhone X was slotted behind those in the top 10 rank

It must depend how you use them. In real life scenarios compared to my friends note 8 I found nd them to be about the same. Lab test problem are different than other test based on what the setup of the phone is geat d towards. One phone might be better when using more of the graphics card than the other. Stuff like that will have differences.

Rebel, we do our best to have the same test run in identical conditions, and we double check the results for best accuracy. Of course, we are open to suggestions on making it better. What would you like to see in a battery test that's different?

Actually not sure if there has been an article about this, but I would like to see how these tests are done, what do the tests test? I have no idea how you guys test these smartphones

Look at the disappointing battery life on Note 8 compared to all the others.......ha ha haaaaaa... I think these results are more credible and accurate than CR ones.

Assuming is proof of nothing. Although your opinion might have some merit or not you are not qualified to say otherwise about either test because you were not there or you did not do a test to prove otherwise

Hey Phonearena, please give breakdown of battery life results as well. Single number is not really helpful.

We have one synthetic test that gives one number. We double and triple check everything to make sure it's done in identical conditions with all phones - display brightness is identical, airplane mode for no notifications and so on. What would you like to see improved?

I never use phone with airplane mode. Unless I am in actual airplane. What would I like test to tell, how long battery would last in following scenarios: YouTube/Netflix playback of video. Not locally stored video. Video recording at full resolution. Google Maps in driving mode. FaceTime/WhatsApp call.

By the chart comparison, I should getting myself Sony Xperia XZ1 Compact with an excellent battery endurance albeit it has a small battery than this Razer phone with a large battery capacity but not too impressive in battery endurance.
