Author: Asus ROG Phone 7 is a gaming beast! But is it the best phone for streaming? Let's find out!
Familiar 6.78-inch, 165Hz AMOLED display
Asus has been carrying forward many of the ROG Phone display specs for a few generations now. With the ROG Phone 7 you get a familiar large 6.78-inch AMOLED panel with a 20.4:9 aspect ratio and 2448x1080 pixel resolution. That works out to a crisp 395 ppi. Once again, the panel can refresh at an industry-leading 165Hz alongside a touch sampling rate of 720Hz. Asus is still shopping at Samsung for its panels. This one is a Bespoke Panel from the Korean giant using the E4 display tech.
This, however, is not the exact same panel as the ROG Phone 6 generation. It is a newer generation that brings about some improvements, notably a higher maximum brightness. Asus now advertises a whopping 1500 nits of max brightness at APL1 (1% of the display active) and 1000 nits at APL100 (100% of the display active).
In our standardized testing, we managed to measure 505 nits of maximum brightness on the slider for the ROG Phone 7 and 1051 nits in max auto mode when in bright lighting conditions. While not industry-leading, both figures are a notable upgrade from the ROG Phone 6 generation. Plus, they are perfectly adequate for comfortable outdoor use. As a side note, you shouldn't mind the small number deviation compared to the ROG Phone 7 Ultimate. It can easily be attributed to margin of error while measuring and "panel lottery".
While contrast is technically infinite on this panel, Asus advertises a much more quantifiable 1,000,000:1 figure.
High refresh rate handling.
Like its predecessor, the ROG Phone 7/ 7 Ultimate has a 165Hz refresh rate. It is accompanied by 720Hz touch sampling rate for the lowest possible input lag.
Asus engineers have never been satisfied with simply getting the fastest available hardware, though. Just like its predecessors, the ROG Phone 7/7 Ultimate comes with extensive tuning to every part of the input and output chain from the display down to the bare metal, through the Android core and rendering pipeline and back to the display itself. This has allowed Asus to get the total end-to-end input latency on the ROG Phone 7/7 Ultimate down to a mere 23ms in 165Hz mode. Impressive stuff.
The ROG Phone 7/7 Ultimate generally handles its refresh rate in a very straightforward manner. Opening the display settings up, the user is presented with an extensive list of refresh rate modes that cover all of the modes the panel can operate at, as reported by the system - 60Hz, 90Hz, 120Hz, 144Hz, 165Hz and an Auto mode. Generally speaking, the higher the refresh rate, the more strain you put on the battery, so it is important to manage this setting properly.
Generally, the specific value options operate as simple hard switches. This means that if you select a particular refresh rate, you can generally expect the UI and most of your apps and games to run at that refresh rate, whether they can take advantage of it or not.
Battery life
Asus has always prioritized battery endurance and longevity in its ROG Phone devices. The bar is set pretty high, and luckily the latest ROG Phone manages to deliver.
Both the ROG Phone 7 and 7 Ultimate have a total of 6,000 mAh worth of battery capacity, just like their predecessor. Like those and the ROG Phone 5 and 5s before that, the battery is actually split into two symmetrical 3,000 mAh cells.
This works pretty well in conjunction with the center-PCB design for the internals and the matching cooling system. Everything is synergistically designed together in this manner.
Asus has another design trick also carried forward from last year - MMT battery technology and a double-wired split design. MMT stands for Middle Middle Tab and increases the energy density in a battery by charging it from the middle outwards instead of from the ends, which lowers impedance and temperature.
Lower temperatures allow higher wattage charging to be sustained for longer periods before entering trickle charge (constant voltage). So, technically, what Asus has done here is approaching the problem of tapering-off charging wattages in a different way, through MMT tech, in place of simply a larger single battery. Neat!
Just like its sibling, the ROG Phone 7 managed an awesome endurance rating of 131 hours in our proprietary test. It did great all-around in both on-screen and off-screen tests. The offline video playback number is particularly impressive.
Charging and battery care
Not only is the ROG Phone 7 overall battery design carried forward from the ROG Phone 6, but so is the 65W fast charging. It is partially enabled by the split design and MMT technology of the battery packs. Native charging on the ROG Phone 7/7 Ultimate goes by many names - Asus HyperCharge and Direct Charging. We are happy to see that Asus is still using standard USB Power Delivery tech to accomplish its charging - PD + PPS (3.3V - 11V @ 5A; 3.3 - 21V @ 3.25A). A pretty elegant system that is USB PD compliant. The 65W charger you get in the box is versatile and can even power some laptops.
Like its Ultimate sibling, the regular ROG Phone 7 charged reasonably quickly off its 65W charging brick. It went from dead to 40% in fifteen minutes and then 69% at the half-hour mark. A full charge took just oven an hour. Admittedly, this is not the fastest charging rate ever and in fact it is a bit slower than the ROG Phone 6 generation. It is about on par with what the ROG Phone 5 family managed. Since Asus has not changed its charging and general battery tech for a long time now, we can only assume that the longer charge time was a deliberate decision. We noticed that the phone spent a good 12 minutes trickle charging from 99% to 100%. So, there's that.
Asus also takes battery care pretty seriously. This is not a newfound priority either, as previous ROG Phones have also enjoyed more than a few extensive options and features in this regard. Starting with the ROG Phone 5, everything related to PowerMaster is merged and organized within the battery settings menu for added convenience.
Speakers and audio output
Audio has always been just as much of a top priority for Asus as visuals and general performance. Figures, seeing how it is arguably one of the most difficult aspects of a multimedia experience to truly nail down. Living up to its pedigree, the ROG Phone 7/7 Ultimate has two large, symmetrical, front-facing stereo speakers at its disposal.
Asus lovingly refers to the entirety of its audio setup as GameFX, but that name shouldn't fool you since there is a lot more to like here in general audio quality and prowess beyond just gaming-centric features.
Let's start with the hardware first. Each one of the two speakers is a 5-magnet, 12x16 Super Linear Speaker with a max excursion of 0.8mm. That number might not sound like a lot to any audiophile but remember the kinds of space constraints Asus is working with. Each one of these speakers is connected to its own dedicated Cirrus Logic CS35L45 mono amplifier.
This is all carried over from the ROG Phone 6. What is new this year is three-dimensional encapsulation Bass (dBass). Thanks to full-fill in the speaker chambers, Asus has increased the virtual speaker-box volume by 50% compared to the ROG Phone 6 - from 1cc to 1.5cc equivalent. And Dirac Virtual bass further enhances low and mid-frequency response.
Like its sibling, the ROG Phone 7 has some of the cleanest and most crisp audio outputs around. It gets pretty loud as well, with no noticeable distortion. It is not quite as loud as some of its predecessors, but it does make out for that with a wide and rich sound stage.
The ROG Phone 7 has an impressive frequency response curve. Even more so once the AeroActive Cooler 7 is attached with its built-in subwoofer. As expected, the additional speaker performs well and has a noticeable effect on low-end frequency response.
Covering the other bit of audio hardware - the 3.5mm audio jack gets to benefit from the Hi-Res Audio (HRA) certification of the ROG Phone 7/7 Ultimate. That means it can process and play audio files at 24-bit/96kHz or 24-bit/192kHz and output that to a compatible Hi-Res Audio certified output device.
New this year is the Dirac Virtuo headphone spatial audio enhancer. It works on any connected set of headphones and employs high-resolution binaural room impulse response technology to restore speaker crosstalk and correct the stereo soundstage. The desired effect is to make it so that sound seemingly comes from a pair of premium stereo speakers in front of the listener as opposed to from inside their head.
The ROG Phone 7 supports all major Bluetooth audio transmission standards, including aptX adaptive, aptX Low latency, LDAC and AAC.
The ROG Phone 7/7 Ultimate's audio prowess goes way beyond hardware. A few years back, Asus partnered with Dirac to leverage their audio platform's unique customizability. This has been carried forward to the ROG Phone 7, as well. You still get all of the systems and behind-the-scenes algorithms as last year, only this time better and improved.
Let's start the software tour with AudioWizard, the centralized audio hub on the ROG Phone.
It offers access to a 10-band equalizer and a total of four pre-made modes: Dynamic, Music, Cinema and Game. Music is meant for general use, Cinema has a slightly wider sound stage and enhances bass and vocals. Game mode has the widest sound stage of the bunch and enhances small sounds like footsteps and high frequencies for a better spatial location.
Finally, there is Dynamic mode, which intelligently switches between Music and Game modes depending on whether Game genie - the Asus in-game overlay is active or not. Our audio tests were done using the default Dynamic mode.
There is truly a lot that Asus and DIRAC have crammed under the GameFX umbrella. A big chunk of the press materials now talk about Dirac Virtuo, which mostly seems to revolve around better spatial audio.
It brings a total of three things to the table. A better center image with more dynamics promises to pick up and enhance "center stage" content better in particular by delivering better sound location and separation, higher contrast and quality and depth to bass in particular. That better spatial sound separation is also leveraged in game mode to better image things like footsteps and their location relative to the user. Finally, the bass notes should sound more natural and better isolated and clean, thanks to better spatial audio.
Another system in place on the ROG Phone 7 Ultimate is MIMO, which stands for Multiple-Input and Multiple-Output. In short, it is a system traditionally found in luxury automobiles that treats a stereo speaker system as one unified system and co-optimizes its summed impulse and frequency response instead of dealing with each speaker in isolation.
