Huawei Mate 20 scores best battery life of any flagship in 2018

Huawei Mate 20 scores best battery life of any flagship in 2018
The Huawei Mate 20, the more affordable sibling of the Mate 20 Pro, might be one of the most underrated phones out there: it not only packs the first 7nm chip on Android, putting it among the fastest Android phones in existence, but it also has a large, 4,000mAh battery that is coupled with a power efficient LCD screen.

How does it all work together?

Quite impressively actually: the Mate 20 had the highest score of any flagship phone in 2018 when it comes to battery life!

With a score of the whopping 14 hours and 26 minutes, it's head and shoulders above the competition. Take a look at the chart below to see the astounding difference in battery life with the Mate 20:

Battery life (hours) Higher is better
Huawei Mate 20 14h 26 min (Excellent)
Apple iPhone XS Max 9h 34 min (Excellent)
Apple iPhone XS 8h 37 min (Excellent)
Apple iPhone XR 11h 1 min (Excellent)
Samsung Galaxy Note 9 8h 56 min (Excellent)
Samsung Galaxy S9+ 8h 5 min (Excellent)
Samsung Galaxy S9 7h 23 min (Good)
Google Pixel 3 XL 7h 39 min (Good)
LG V40 ThinQ 6h 21 min (Average)
LG G7 ThinQ 6h 32 min (Average)

The only device that even comes closer to it is the iPhone XR, which scored a respectable 11 hours of battery life, but still compared to the Mate 20 is way behind.

In real life, you can get two days of usage out of the Mate 20, while with most other phones this year, you can get 1 full day, but usually not more.

Charging time (minutes) Lower is better
Huawei Mate 20 98
Apple iPhone XS Max 209
Apple iPhone XS 185
Apple iPhone XR 192
Samsung Galaxy Note 9 109
Samsung Galaxy S9+ 105
Samsung Galaxy S9 107
Google Pixel 3 XL 123
LG V40 ThinQ 109
LG G7 ThinQ 107

When it comes to charging times, the Mate 20 ships with a fast charger in the box and despite the big battery size, it's able to fully recharge the battery in just about an hour and 40 minutes. This is not quite as fast as the ultra-rapit charging on the Mate 20 Pro, but is still plenty fast.

So... will this incredible battery life convince you to put the Mate 20 higher on your wish list for the holidays? Let us know in the comments below!

Hard to trust this test when according to it an iPhone X has similar battery life that of Note 9. When LITERALLY every single test from every single site and youtube video says otherwise. And that's just one of the 100 examples I can give.

Check this youtuber: Mrwhosetheboss. He runs battery test on OnPlus 6T, iPhone XR, XS Max, Note 9 and Mate 20 pro. The winner is again Mate 20 Pro with almost a hour over second - Note 9. Interesting is that XR is last - on 5th place. This is against PhoneArena tests and all time second place.

The Mate 20 isn't officially available in the US so this can't be for US only phones. Based on that assumption the Vivo NexS is easily the battery king of flagships. Disclaimer: I own a NexS. But GSMArena arena and users on XDA agree. That's credibility that PA can only dream of. On another note, I don't know why PA keep embarrassing themselves with their nonsensical battery tests. They're so far from reality that even Donald Trump would cringe.

Its note just one youtube video, its literally every single video comparison, every single site besides PA that magically show different charts. Its as if PA's test is made in a way that it mostly benefits iPhones. Weird right?

Well, that's simply not true. Most tests confirm that the iPhone XR that you are so fervently attacking has a great battery life. Sorry to disappoint you.

No one is attacking the XR. It's your bogus battery tests that are in question here. Please cite your "most tests" because we've been giving specific, credible sites (GSMArena and XDA on my part) that debunk your tests. The numbers are backed up by many other credible tests. Your procedure apparently runs a web based script and in most cases your numbers closely match the browsing numbers from GSMArena and that's it. The XR may have good battery life but you're the only ones that say it's better than the Note 9. Take a good look at yourselves before criticizing us.

It clear that the test is easier on LCD screen, definitely shows lots of whites.

Wrong... The best battery life flagship phone is Mate 20X. It is proven by mobile tech YouTuber in their YouTube video.

It's a 7.2-inch "phone", guys. Of course, it's going to have the best battery life. You could as well compare it to a tablet at this point.

Why have you not done the Mate 20 Pro? Surely you can block the Auto Screen Brightness by putting something over the light sensor and setting it to manual, and I am pretty sure the standard Mate 20 does the same thing depending on light.

Because it would make their clients product (the iPhone) look even worse. It's not something to worry yourself about anyway since no one with a brain takes their battery testing seriously.

We have explained in the Mate 20 Pro review why. The reason is that some Huawei phones when set to manual brightness still automatically adjust the brightness level. For our tests, it's essential that brightness level remains the same throughout the test and since it is impossible for us to set a fixed brightness, we could not do our test for Mate 20 Pro. We have reached to Huawei a few times now and we still have not received an explanation as to why this happens. This is true for the P20 Pro and Mate 20 Pro.

My Mate 20 X could easily have 10 hours of screen-on time.

Between the big battery, Huawei’s fast charging, and the power management of the Mate 20, it’s no wonder that it scored so well. The most important aspect of a smartphone (IMO) is whether it has great battery life or not, and Huawei has nailed it.

Huawei is coming on strong man, can't even deny it. As long as they're banned here, I probably wont get one, but if it's lifted, oh yeah.

They are definitely coming on strong. I get my Huawei smartphones from Amazon, and even though are international, they come with the necessary U.S. LTE bands. They've won me over as a fan for sure.

So that's a good place to look?

Amazon, eBay etc. They're not banned at all. You just can't get them through carriers. The fact that Oneplus and ZTE can sell through carriers shows it's a bs ban on Huawei.

Right on.

Absolutely. I tend to get most of smartphones through Amazon now, as I prefer to buy them GSM unlocked. No carrier bloat and all that. I prefer Amazon because in most cases you have about a month to return what you purchased for your money back.

I actually just received my mate 20 x through a seller on ebay. package came 2 days earlier, well packed, and everything fine inside. after a few hours of trying to figure out a way to install google services, because huawei's play store is all in chinese, i was able to have access to all my google accounts. I'm pleased to say that i am amazed at how great this phone is vs its competition. it really has everything i want, and im coming from my beloved zte axon 7. Also this works great on Tmobile, as that is the provider i have been using for 8 years now.

If anybody want to buy phone never consider any kind of tests from phonearena. Better go to YouTube and watch your self.

It was obvious the Gsmarena battery tests for Mate 20 series were flawed and they refused to correct it despite the results making absolutely no sense.

LCDs are still the most power efficient displays on the market. Sure, having a backlight on constantly in all scenarios can discount a few points. But overall, they’re still just more efficient. OLED has an issue with APL percentage counting heavily towards its efficiency. Since the vast majority of the content on the Internet displays content with average picture level above 65% (how much white displayed content has), you inevitably use more power than you save. mLEDs won’t have these issues; that’s the real display technology we need in our lives. OLED is just a momentary stopgap.

Here is my real world experience with the Mate 20 Pro. Had it since the day it came out. If I go "hard" on it, the lowest I've gotten the batter is 56%. That's with me getting up at 5am one day, and checking the battery life the next day when I wake up. I carry 2 phones with me at all times, the Mate 20 Pro and the Samsung Galaxy S8+. The 56% came the day I neglected the Samsung and did everything on the Mate. The LONGEST I've had the battery go so far was over 5 days. Even then it was still over 30%. However, these were 5 days that I wasn't working so I did not use it for anything other than taking photos (I was in China, so definitely wanted to take pics). This is in no way a "scientific" test, but just my real life usage of the phone.

5 days with the Mate 20 Pro with a SIM card in it? I could not go 2 days between charges.
