The brightness in the display tests for many phones has values that are lower by more than 10% when comparing to at 50% APL. Are the values for 50% APL or 100% APL?

I have read your review on Realme 7 Pro. Coming to Speakers quality it was not good and mobile was VIBRATING at back panel. Have you observed this from your end while reviewing the product. Thanks...

I regret, that sunlit contrast ratio is no longer tested. It was a major reason for me to select my last phone. Yes, screen glare is quite important and can offset high nits easily, and there are relevant differences. One of the last tests revealed the top performer at 5.98 when the second was at 5.17 which is a notable difference.
Btw, there are well existing standards (even regulations) for lighting conditions in professional environments (at least in Germany), which demand between 500 lx (normal office work) and 1500 lx (e.g. watch makers) on the desk and at least 300 lx in those environments.

Samsung Galaxy S7 14:50h video playback is impossible!


my sony xperia is not working

What made them different from other smartphone sites was precisely the audio tests with headphones. Now they are one more, camera tests can be found in many places. Audio testing was what made them different.

  • stan

appreciate the new loudspeaker test reasoning but would really welcome comments on the in call quality and loudness of the earpiece because other than multimedia, calls are the primary use of a phone

  • Aresias

Do you do endurance tests with several loops on the Benchmarks to see if the phone has throttling?
How are your benchmark scores calculated? Is it an average of several loops? if so how many?

Haziri, 17 Dec 2019Please I'm not so good with audio and stuffs, but I have a ... more250 ohms is probably too high impedance for a typical cellphone audio amp to drive with decent volume best to stay around or below the 50ohm range,

Thanks to GSM ARENA for providing this explanatory information and their specific handset stats.

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?
