This flagship's battery life puts all others to shame

This flagship's battery life puts all others to shame
With Huawei's phones in the penalty box until mid-August when we will know if the White House will allow them to receive further Android updates, there aren't many options for Android flagships with great battery life any more. 

All other popular ones like Samsung's S-line or LG's G-line, come with Quad HD resolution displays, effectively taking a way higher toll on their batteries if normalized for capacity, as they have almost double the pixel number to light up and push around. Only Huawei held strong with 1080p resolution displays on its flagships, and coupled them with large battery capacities to boot, resulting in record battery endurance for the category.

When it comes to endurance on a charge from flagships with 1440p displays or higher, we've noticed a consistently worse performance compared to those with similar specs but lower resolutions. Granted, the default screen resolution on phones like the Galaxy S10 is FullHD+, but there are still more than 4 million pixels that have to be lit up. That's opposed to two million or so on 1080p displays, so it doesn't help to nudge the battery life up even one iota. Twice the number of pixels to push is perhaps the single biggest reason for QHD phones to score on average a 20% shorter endurance on a charge compared to the lower resolutions.

The best battery life among high-end phones goes to...

Thankfully, Huawei is not the only play in town when it comes to that very combo, and there are now more choices with "enough" display resolution, high-end chipsets, and huge battery packs. Chief among those is the new Oppo Reno that is hitting shelves globally this week (well, with the exception of the US, of course).

Not only does the Oppo Reno 10x Zoom edition offer the same periscope zoom lens solution as the Huawei P30 Pro, but it also comes with a Snapdragon 855 chipset on board, a 1080p display and a 4000mAh battery. Needless to say, these specs catapulted it right at the very top when it comes to battery life. No other flagship phone manages to come close but the very same P30 Pro whose future is on ice now, thanks to the poker game between the US and China.

What, we can't call it flagship if it doesn't have a Quad HD display resolution or above? Well, just look at how it aced our demanding battery life test, and remember that it carries the same chipset that the S10 has, yet offers unique camera features that the flagship Galaxy doesn't. One thing is for sure, though - if you like a phone with a high-res display, wait for its battery life tests. All other things being equal, its endurance on a charge will be much worse than phones with sub-1440p resolutions, all for a pretty negligible difference in perceived pixel density, at least with the naked eye. Are you still chanting the "QHD or bust" mantra?

In fact, the Reno 10x Zoom edition is the best flagship phone we've ever tested in terms of battery life, managing to keep its screen on for more than 12 hours while running our heavy custom script at standardized brightness setting. 

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.

hours Higher is better
OPPO Reno 10x Zoom
12h 3 min (Excellent)
OnePlus 7 Pro
9h 10 min (Excellent)
Samsung Galaxy S10+
7h 59 min (Good)
Samsung Galaxy S10
6h 45 min (Average)
Apple iPhone XS Max
9h 34 min (Excellent)
LG G8 ThinQ
7h 30 min (Good)
Samsung Galaxy Note 9
8h 56 min (Excellent)

This means that the phone could easily last you two day with normal usage, and a weekend away from the charger is not something we are used to associate with high-end handsets. Too bad that this baby doesn't sell officially in the US though you would still be able to hook it to T-Mobile and AT&T networks if you get it elsewhere.

Fast charging times, too!

The icing on the cake and the cherry on the top? Well, it must be the quick charging time we tested on the Oppo Reno. While less than an hour and a half is not that exclusive any more in the world of high-end phones, let's not forget that the phone comes with 4000 mAh battery capacity, and still charges faster than the S10+ which has a smaller battery. Sweet!

The reno is not a flagship , its camera is not better than samsung phones ,and your bettery test is bad and not reliable . The reno is good phone , but in terms of battery in flag ships the p30 still take the cake , and if its price goes down it makes for an even greater deal to have one

Reno is a flagship phone. Anything that Oppo and Vivo make nowadays are of the highest quality. They have been on a roll for years now and are top five worldwide in terms of market share. All without having to sell in the American market.

That phone doesn't do what a Galaxy does. So it having better battery life should be expected, but it is pointless to compare a feature rich phone to a phone having less capabilities.

You are correct. I can also say the same thing about the galaxy. There are compelling features on the Reno that can't be done with a galaxy. Both phones are excellent purchases though.

You're wasting your breath with these guys poptart. The majority of the people commenting have never seen and certainly not used any Oppo, Vivo or Xiaomi phones. All they know are Samsung and iPhone because the US has the worst selection of phones amongst major markets. Galaxy phones are top of the line but don't have great battery life. If there's no juice what's the point of all the features? The Reno has superb battery life and finally took the title from the Vivo Nex due to a more efficient soc.

Sure, good battery life. But they are one of the manufactures which provided the worst software support for non-China version. Find X, R15 series and R17 series still haven't received Android Pie, together with slow security patch updates.

If you want longer battery life, it's easy : disable the bloatware software that you don't use (no root required) (install adb on your pc and enable USB debugging in developer options) : adb shell pm disable-user --user 0 com.package.example Replace com.package.example with the desired package. Just be careful what you disable though, you might get into a bootloop and you'll have to hard reset the phone (from recovery) . My S8+ is flying without Bixby and other junk software hogging on the battery and processor! If you want to take a step even further, root your phone and delete the bloatware instead of disabling it. Sorry huawei users, but you're not allowed to root your phones. Hua-who decided that for you. Guess you'll have to settle with using your phones in guest mode instead of administrator. Tough luck!

Or just buy a phone with a big battery and confirmed good battery life. Why bother with all the adb rooting stuff? This isn't xda.

Because It makes me use my brain and I love a good challenge. We're living in a digital era. Adapt or move out of the way..

Samsung Galaxy S10+ doesn't have a smaller battery than Reno. It has bigger one infact. PA plz check your facts before posting.
