Please I'm not so good with audio and stuffs, but I have a question. Using the OnePlus 3.5mm adapter can you game well using the bayerdynamic dt 990 pro which has 250 ohms (impedance) without an amplifier?

The headphone jack sends a low voltage signal as a source to be amplified it itself is not an amplifier to add gain to the signal or overall volume. Now if the signal is clean, low noise, etc then that is more of what can drive an amplifier to allow solid volume. But maybe we are just misunderstanding each other....and actually I may need to dig into technical details on how a powered signal jack signal operates when attached to a passive transducer...I think I kinda know what you are saying now.

AnonD-170990, 24 Aug 2013I'm a little disappointed with the battery life test, as with many other users, I believe that... moreWhile I agree that having airplane mode on while watching videos isn't totally accurate or reflective of the avg person's use, I'd say it is accurate & actually necessary in terms of this test. In fact, I'd say this is the only "true" way of testing for this metric, i.e. video playback & ONLY video playback. If airplane mode is off you're introducing the possibility of more variables skewing the results. With it off, you'll start getting calls, texts, messages, notifications, updates, etc, which not only differ from person to person, but also from time to time, e.g. time of day, date, weekday/end, yesterday/today. Now you're no longer testing purely video playback time. On top of that none of the results can be directly comparable (one of the main purposes of this test to begin w/), making them just as meaningless as the (pre-2016) 50% brightness test. In a scientific test, in order to get the most accurate measurement of the one thing you're testing for, you must eliminate all other variables, or as much as possible. If not, you're no longer testing for that one thing, but something that's completely up in the air.

nate0, 20 Apr 2019Output signal from that port is AC voltage. Why you would want it in mW?Output POWER is measured and ststed in Watts, or for reproduction in headphones, Milliwatts. This enables easy comparison of the products effective volume capability as W is the standard method actoss the board. There is no point in knowing the voltage output when the load impedance is going to vary.

GSMArena? How will you explain this: https://imgur.com/MSZvLlH
How come a phone with battery index 83 has more talk time, more web browsing, more video watching battery life THAN a phone with index 86 that had all three battery parts lesser ?
How this battery index is any good ?

Your audio measurement equipment is seriously outdated and the measurements don't reflect the actual quality that is available. Very misleading especially in the case of mobiles with built-in quad dac and such.

While testing the audio through the headphone jack, it would be very informative to take the Vrms measurements to indicate the drive capabilities of the output amp for high impedance headphones. Also the output impedance of the amplifier would be highly useful for IEMs.
Sorry late to the party. Not sure if this question has been asked. When you test loudspeakers, you take measurements with the handset loudspeaker facing the loudness meter at a distance of exactly 1m. What happens if you have a bottom firing speaker and an earpiece speaker?

Can you do tests on the extent to which an AMOLED dark mode would affect battery endurance? Would probably require a custom browser that has a built in dark mode feature (e.g. Samsung Browser) to see the full benefits but I think it would be an extremely useful metric in comparison to Light Modes/LCD screens, given how popular dark modes are

Can you release a Display table tool like the battery life test? At this point Noia 9 pureview is the record setter for large screen smartphone Sunlight legibility, oddly with a lower maximum brightness. I would like to and be able to compare/contrast devices in this category.

hi GSMArena,
it would be very helpfull if you could measure the output power of the headphone jack in mWatt.

Would anyone know whether or not there is difference in performance between n950fd vs n950f dual and single sim model?
Many thanks in advance.

For my opinion
in order to measure how much longer battery life is
In common everyday life usage
1. Calling
2. Web browsing (SOT of Web browsing)
3. Youtube
(SOT of youtube video playback)
4. Gaming (SOT of gaming)
5. Camera(Photo/Video) (SOT of Camera)
Battery fully charged 100% and turn max brightness100%
calling, until battery down to 1%
follow the same procedure for web browsing, youtube, gaming and camera.
Finally test its 3G/4G standby time
That are what everyone needs to know.
Regards,

I think GsmArena battery life synthethic tests have something wrong:
- accordig to your table, with the standard 3 hours of use per day, most of modern phones fall in the 75h-100h bracket, that is about 3-4 full days. I never heard anyone in real life whose phone can last so long, nor close. Usually people are happy if they can last 1 full day, the luckiest get half the second day.
- looking to the single phones some strange results come out at first glance: there are some phones well-known for their extraordinary battery life (e.g. BB KeyOne) that fall down in the pack anonymously, others like the Huawei Mate(s) where the 8 is much better than the newer 9 and 10, that’s unlikely. These are just the most evident.
I don’t want to directly compare your results to other site’s, i know the test methods are different, but when i tried to find phones with good battery life i looked at reviews and “charts” in various sites, among them the two famous ....arena.com, but looking at yours i was surprised by the strange differences in many phones’ rankings.
Maybe your tests are too artificially built, I don’t think those phones actually last 3-4 full days on a single charge on a real life environment (3G/4G data connection always on, not browsing on limited pages probably in cache after the first time, etc...).
Do they really last for days before you publish any battery test?
