For my opinion
in order to measure how much longer battery life is
In common everyday life usage
2. Web browsing (SOT of Web browsing)
(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.
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, thatÂ’s unlikely. These are just the most evident.
I donÂ’t want to directly compare your results to other siteÂ’s, i know the test methods are different, but when i tried to find phones with good battery life i looked at reviews and Â“chartsÂ” in various sites, among them the two famous ....arena.com, but looking at yours i was surprised by the strange differences in many phonesÂ’ rankings.
Maybe your tests are too artificially built, I donÂ’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?
Anonymous, 04 Oct 2017Apologies if this has been asked before but with the loudness of the outputs from the line out... moreI came here for the exact same reason. Maybe the other measurements indicate this? Either way,it would be great with a comparable number for each handset.
There is a very important battery benchmark missing.. And that is the battery time when gaming. An easy way to test would be to run a CPU/GPU benchmark like geekbench and Antutu over and over until the battery dies, to get an estimate of the battery time for intensive use... The current benchmarks for video, browsing are very easy to be tweaked by phone-makers.. Running a long-running max-benchmark (that the vendors also want to look good at, when they compare performance) will ensure that both the CPU/GPU benchmarking scores are kept honest and that battery times are valid even fro intensive usage.
Apologies if this has been asked before but with the loudness of the outputs from the line out jack is there any way you can put an actual figure to this rather than just saying it's loud or not very loud? I'm sure your test equipment will give you an output waveform so would be good to see these for comparison.
Z5 premium with an hour video play back, an hour Internet and an hour 3g calls I would have to charge up every 4 to 5 hours. Not sure where 66hrs comes from. Am I not understanding your tables?
Could you please tell exactly what kind of video you use for battery test of video playback (resolution, compression type, bitrate, audio...) or perhaps provide a download link of your test video (if not copyrighted)...
I am trying to guestimate state of batteries on bunch of old phones ;-)
Brought a SONY XPERIA XA Nano SIM model F3113. Feel satisfied with performance except low audio which Sony themselves admitted.
One more question about audio:
For devices with dedicated HiFi DAC, are audio output tests ran on the HiFi mode or normal mode?
About audio test: Which sample rate/bit depth are you using for playback and recording? are they 44.1k/24bit?
handset is very impresive look,weight,water proof,also 4G ,,,,high quality speker,
this very usefull product,,,,
I love lumia and special 650 good phone
But some future is missing
1 battery back up ...2000mah is poor for life stayl
2200 to 2500 is better of this device
1 only 720p no hd record
And ram 1gb
1.5 to 2gb is better
And other think is excellent ...nyc
Friends you can buy ...no probably ...but carry with power bank
My sony expirea e4 battery draning verry fast and also while doing wall charging it's charge but 10% charge in 1 hours this never happen before please resolve my problem or give some solution
