BlackBerry KEYone battery life test result really hits it out of the park


The BlackBerry KEYone is a phone with a keyboard in 2017. And while that was pretty much the standard 10 years ago, in 2017, it's the only such phone.

But that's okay: it's meant to be that way. The KEYone has a 4.5-inch display with a 3:2 aspect ratio, and a laser focus on productivity and email, while doing all the things modern Android phones do. The phone is not exactly beautiful, but it's practical, it's meant to get things done.

One key aspect of a practical phone, however, is clearly its ability to deliver great battery life. Does the BlackBerry KEYone live up to expectations of great battery life?

Well, thanks for asking, because this exactly what we wondered ourselves and what we have tested.

And we have some great news for you: the 3,505 mAh battery on the BlackBerry KEYone does indeed last. It's not the only factor that contributes to great battery longevity: the KEYone runs on the Snapdragon 625, a mid-range chip that is the first one in this class of chips to be made on 14nm manufacturing, ensuring modern power efficiency.

In our daily experience, the BlackBerry KEYone lasted a full two days between charges on most occasions. Sure, if you are a heavy user you might want to juice it up before day two, but if you are more of an average user, you will get those two days. Our tests confirm that: the KEYone scored an impressive 12 hours and nearly a half. This is almost a 50% improvement in battery life over popular flagships like the Apple iPhone 7 and Samsung's Galaxy S8.

Battery life (hours) Higher is better
BlackBerry KEYone 12h 26 min (Excellent)
Apple iPhone 7 7h 46 min (Average)
Samsung Galaxy S8 8h 22 min (Average)
LG G6 6h 9 min (Poor)
Charging time (minutes) Lower is better
BlackBerry KEYone 115
Apple iPhone 7 141
Samsung Galaxy S8 100
LG G6 97

Another aspect of the battery experience are recharge times: how much time does it take to juice up the battery on the KEYone? It took us slightly less than two hours to get from 0 on the battery meter to a full 100%. This is not the fastest around, but not too far out. It's okay. And it's definitely better than no quick charging at all, as we still see on devices like the Apple iPhone.

So there you have, the BlackBerry KEYone is indeed a great productivity phone with outstanding battery life. It should be available for some $550 in the United States sometime this month.

50% as long means the exact opposite as 50% longer

this phone size is bigger than S8 and has much smaller screen.. combine that with low-end SD625

Well it has one of the smallest displays around and only a 1080p resolution, what did you expect?

"THE KEYONE BATTERY LASTS NEARLY 50% AS LONG AS THE ONE ON IPHONES AND GALAXIES" ...50% as long as on iPhones OR Galaxies ? If it is 50% as long as on Galaxies, then it is 100% as long as on iPhones.

"THE KEYONE BATTERY LASTS NEARLY 50% AS LONG AS THE ONE ON IPHONES AND GALAXIES". Something is really wrong with this text :)

I see something wrong with the title too. It should be: THE KEYONE BATTERY LASTS NEARLY 50% MORE THAN THE ONE ON IPHONES AND GALAXIES

Who wrote this article? It has a bad introduction with a hard to follow body.

Now charge 300 quid for it and I'll buy one, otherwise I'll just stick to what I have.

I'm glad I paid the money for it. I haven't enjoyed an android this much since the Samsung Galaxy S3.

4,5" display, SD625 and 3505mAh battery. What did you guys expect?

BlackBerry Mobile/TCL and BlackBerry definitely have a winner on their hands with the KEYone. This article hits the nail on the head as to why BlackBerry Mobile/TCL chose to go with the SD 625 SoC, as opposed to a flagship the one. The incredible power management capabilities of this SoC combined with the big battery makes for amazing battery life, which is exactly what they were aiming for with this handset, and it's something that important to many smartphone buyers that prefer that. Great battery life is a staple of productivity, and this handset has that in spades. This handset is about productivity and getting sht done, not watching movies and videos, and playing the latest games on a smartphone. As noted in comment #12, when you add the quick charge with the SoC and battery, you get one handset that will go on and on, and that's what's most important to the users in the market this handset is intended for. Want the latest and greatest flagships with the latest SoC that will provide extreme power, but that's also power hungry? This handset isn't for you. Want a handset that's going to give you two days-and-possibly-more-battery life and power management that you can always count on to get things done without having to worry about constantly charging your phone? That's what the KEYone is for. Kudos to you, BlackBerry Mobile/TCL and BlackBerry.

Only thing I wish for is a 4gb/64gb version. Would have loved to see the 3gb/32 @ something like 489 then the 4/64 at 549

Almost every review is forgetting to talk about their quick charge options. BlackBerry KEYone also ships with support for Qualcomm’s Quick Charge 3.0 technology thanks to which the phone can be charged to 50 percent in around 36 minutes, the company claims. In other words, the KEYone will not only feature a massive battery, but also one that can be recharged relatively quickly. Finally, BlackBerry also promises that its Boost technology will allow users to “turbo charge” their KEYone units and make the most of the short time that’s available to them.

Does anyone have an opinion on Adguard's effect on battery life? I love the app, but I think it is killing my battery and making my phone run hot. I'm wondering if it will wreck the test results shown here on my upcoming KEYone. Thx.

compared to iphone 7 and s8, this is a steal. and looks better and more secure. total winner in my opinion.

Totally agree. +1.

A steal? You're getting a midrange chipset at that price tag. If it were the same chipset as the S7 or S8, then I'd agree...

I had the S7 edge, and the S8+, and I'm much more happy with the KEYone.

Good for you, doesn't make it a "steal" at that price point...

There's more to consider than the internal. Yes it is a steal for this phone. Go type on your glass and piss off.

If I spend $1000 on the S8+ and $700 on the KEYone, but I'm twice as happy with the KEYone as I was with the S8+, then yes this is a steal for me.

The whole is greater than the sum of its parts. The Cadillac ATS has a standard 4-cylinder powerplant that blows away a few V-8s and doubles up on the MPGs to boot.

The whole still ain't a "steal" at this price point, which is the point of the OP...

I managed to snag one before it sold out. I'm glad I spent the money. It's one of the best phones I've ever used.
