Honor 8 scores big on our battery life test: results compared with OnePlus 3T, iPhone and Galaxy

The Honor 8 is one of the most popular devices in a new category: the so called "$400 flagships".

With a stunning glass design, a pocketable and easily manageable 5.2-inch form factor, it stands out in a crowd. It also features a dual-camera system that makes it possible to adjust focus on your images after you take them, and add an extra layer of blur to backgrounds to make your objects pop. This effect is similar to the iPhone 7 Plus's Portrait Mode (admittedly, it does not quite reach its accuracy). The lucrative $400 price of the Honor 8, much less than the price of flagships the ranks of Apple iPhones and Google Pixels, is another thing to keep in mind. It's made possible by the fact that the phone is sold on the web, and this saves a lot of the staffing and marketing expenses related to selling other phones.

The thing that we want to focus on here, though, is battery life. Huawei phones (Honor is a sub-brand of Huawei) are known for their aggressive app management that allows the company to squeeze the most out of the battery. Is this the case with the Honor 8 and its 3,000 mAh battery?

We put the Honor 8 battery through our battery life tests to see how it holds up and here is what we found out: this is one of the longest lasting phones on the market currently. On our custom test, where all phones have their displays set at an equal brightness level of 200 nits (a level comfortable for indoor use), the Honor 8 scored an impressive 9 hours and 7 minutes. This compares to just 5 hours and 41 minutes on the OnePlus 3T, for example, and that phone is considered a decent performer.

In real life, we have been using the Honor 8 for a long time and we consistently get around two days on a single charge. Heavier use would usually reduce battery life to around a day and a half, while scarcer use can lead to more than two days on a single charge. This is great in our books.

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.

Apple iPhone 7

Samsung Galaxy S7

Google Pixel
7h 45 min (Good)

Another interesting aspect of a phone's battery situation is the time it takes to recharge a depleted battery from 0 to 100%. Having quick charging on board can alleviate a lot of battery pains and while the Honor 8 is not among the fastest phones, it is certainly not too far away.

It took the phone just around 1 hour and 40 minutes to have its battery fully charged using the in-the-box wall charger. Among mainstream phones and its rivals only the OnePlus 3T and Samsung's Galaxy S7 were faster in charging speeds.

Overall, we're impressed with the battery life of the Honor 8. It's one of the longest-lasting "$400 flagships" and coupled with its impressive design, gives it a competitive edge in an increasingly tough market.

You can't compare mid-range(A series) with high-range(Honor 8)...

so it's fine for a mid-ranger to have better batter life than high-ranger? okay, got it

LOL? Honor 8 is a midrange phone, dude. Huawei P9 is their top model.

Huawei's agrressive background app management was the main reason I switched to some other device. Even changing the setting didn't work good on EMUI 4. Don't know if it got improved in EMUI 5

Missing out on notifications and multitasking. This was also one of my main issue with the Honor 8.

I would leave my phone(Huawei Mediapad X2, 32,3) to do some heavy downloads while going to bed. Even with the charger plugged in, giving the 'background run' access, and also changing the battery settings from 'SMART' to 'PERFORMANCE', the apps would get killed and downloads were disturbed. I then started using my older Moto G 2014 for downloads and it did the job nicely even when It was not connected to the charger. Also 'Sleep for Android ' faced the same issue. The app would be killed most often. I even whitelisted the apps in doze settings to see if I get the desired output. All in vein. And it also happened to some IMs quite often but not always. Now, using my 7 Plus. And yeah, I used Mediapad X2 as my daily driver for about 8 months.

If it really got solved then it would be much fun to use Honor 8 at a reasonable price.

Aggressive background activity management is also the reason that the Xiaomi Mi 5 has great battery life. Fortunately I only wanted notifications for email and one SMS texting app. You had to leave them in memory at all times to get notifications by dragging down on their icons in the recent apps area. That put a little padlock on them to show that they were locked in active memory. Wouldn't be a good workaround if you like to get notifications from several apps though. Worth it for me, loved the long battery life.

It would always be great to have a great battery endurance. But the manual options that they give to the users should also work well.

These will all be put to shame by Le Pro 3.

Phonearena - you should update the camera speed of the honor 8 in your benchmark. with nougat it takes shots with the volume shortcut in 1.1 seconds like the pixel. FYI.
