The time below may differ depending on ambient temperature or the status of use.

Battery Life (continuous playback)

Actual battery life may vary depending on settings. The estimated battery usage hours shown below are based on typical usage conditions with “Settings for battery life measurement” as shown in the table below.

Music

MP3 128 kbps

Bluetooth OFF: approx. 32 Hrs

Bluetooth ON: approx. 23 Hrs

 

Linear PCM 1,411 kbps

Bluetooth OFF: approx. 34 Hrs

Bluetooth ON: approx. 24 Hrs

 

FLAC 96 kHz/24 bit

Bluetooth OFF: approx. 25 Hrs

Bluetooth ON: approx. 16 Hrs

 

FLAC 192 kHz/24 bit

Bluetooth OFF: approx. 16 Hrs

Bluetooth ON: approx. 7 Hrs

Video

MPEG-4 384 kbps

Bluetooth OFF: approx. 5 Hrs

Bluetooth ON: approx. 5 Hrs

Note

  • Even if the player is turned off for an extended period, a small amount of battery power is still consumed.
  • Battery life may vary depending on volume setting, conditions of use and ambient temperature.

Settings for battery life measurement

Display

Brightness (*1): Default

 

Sound adjustment

ClearAudio+ (*2): OFF (default setting: OFF)

Equalizer (*3): OFF (default setting: OFF)

Surround sound (*3): OFF (default setting: OFF)

DSEE HX (*3)(*4): OFF (default setting: OFF)

Dynamic normalizer (*3): OFF (default setting: OFF)

xLOUD (*3): OFF (default setting: ON)

Clear Phase (*3): OFF (default setting: ON)

(*1) The maxmum brightness setting shortens the battery life for continuous video playback by about 27 % compared with the default setting.

(*2) The [On] setting shortens the battery life about 37 % compared with the [Off] setting.

(*3) Setting [Equalizer] to other than [None], [Surround sound] to other than [None], [DSEE HX] to [On], [Dynamic normalizer] to [On], [Clear Phase] to [On] and [xLOUD] to [On] shortens the battery life for continuous music playback by about 77 %.

(*4) The [On] setting shortens the battery life about 66 % compared with the [Off] setting.

Of course 28 hours is fantastic anyway. By the way, if WiFi is on, I find it drains in not much over a day!! So I have proved the battery is okay, but its efficiency with my WiFi router at least is poor.

 

It runs Android 4.1, so rather old. The latest firmware 1.11 seems to block rooting, but on 1.0 and 1.1 it has been done from what I understand.


Version 1.0 Partly

Version 1.1 No

On a separate point to battery life, is a point I wanted to make about an observation with battery charging.

 

I have found that if I leave my ZX1 connected to the PC, that after the battery gets to 100% it seems to carry on trying to charge and the ZX1 gets quite warm as well (it wasn't warm while it was charging from an empty battery, only when it was already full). I left it like that for 2 days not realising which probably did no favours to my battery. Although as I got 28 hours of run-time straight after, I may have got away with it. It seems the ZX1 doesn't stop charging, or at least it doesn't like doing so when connected via USB to my PC.

post #5884 of 6318

have the same problem. suddenly looping like that with the WM logo on repeating until battery drain off. Already tried to reset it, 8 sec on button pressing, then back pin reset, but no way.

it literally sucks! How sony can release such products? 900 $ product behaving like that.

 

Called service center in Singapore, again after 30 min explanation, wait and see, the were asking me if we were talking about a blu ray player??? man they do not even listen to customers. never seen such a bad management,

post #5885 of 6318

more over, the few hours i used it, it was warming up quiet a lot.

 

To be more precise, I did yesterday the firmware upgrade through wifi. pls do not do it, this could be part of the problem too….

post #5886 of 6318

anybody sorted out how to do a reliable harts reset??? the system hang up like that, doesn't even go into the operating system….

rubbish, real rubbish.

 

Never never again will do such a mistake! bye bye sony

After doing some reading on general topics on modern battery and charging technology, on certain devices once the battery is full, charging will cut off and keeping it plugged in, you might see the battery percentage dropping. On some devices, the programming or circuit allows brimming of the battery, for eg. once it drops to a certain percentage, maybe 99.5%, the charging resumes and brims it to 100%, so on and so forth. Brimming is thought to be very bad for rechargeable batteries, be it Lit Ion or whatsoever. There are many schools of thought on this and I won't know whether or not which is correct but in my opinion it is better to leave the device in for additional 10 to 15mins after showing full before removing the charger and not more than that for battery longevity. Draining the battery completely once in awhile is actually good to "exercise" the battery and also recalibrates the battery guage for a more accurate reading.

Android 4.1 is plenty new IMO. half a year ago i was running android 2.3 on my phone, witch looks fabulous with MIUI, and has all the usefull features. Just trying android 4.4 on my old phone, it doesnt seem to bring anything new compared to the android 2.3 rom i have on it. But anyway i have Jolla phone now, and love it :biggrin: except its headphone output quality, witch sucks:angry_face:.

 

yes it was on the .co.uk product page, thanks for the answers, seems like rooting is pretty much out of the question right now.

 

So how many apps does it come with? (I would prefer ONLY music player, browser, and play store:ksc75smile:) otherwise need to root the damn thing to get rid of all the bloatware.

It's not bloated with Sony stuff at all...just a few very basic config related things and their own media players of course...but its the Google apps that cause bloat and resource usage!

I agree, Sony should have opted to use a dedicated software offering here although they chose the quick and cheaper route. The upcoming Cowon P1 is what I'm looking out for, no Android bloat and therefore far less CPU power sapping.

It was Android that sold it for me. I wanted the Google Music (and potentially other) streaming options.

And the P1 is still rated for 8.5h of playtime, while zx-1 offers over 20h on cd quality flac.

Thank you for posting this. I hadn't looked the online manual! :)

 

So my 28 hours result for FLAC CD quality is about right considering that 96kHz/24bit is 25 hours. So it looks like I have a healthy ZX1, despite leaving it connected to my PC all weekend which seemed to result in it never stopping to try and charge.

 

Interesting that they don't dare to quote how WiFi affects those times. I can see from my own tests that it really hurts it, more so than Bluetooth.

Speaking of the signal-to-noise ratio… While searching on Google, I found this: http://store.treoo.com/main/sony-nwz-zx1-walkman-digital-audio-player.html; if you go to the "Additional information" tab, it says:

 

Quote:
 Signal to Noise Ratio (SNR): 93 db

 

I don't know where they got that from; none of the Sony websites show such a figure, and it's quite close to the measured value linked earlier in the thread. In any case, it seems to confirm that indeed the "24bit" support is a figure of speech rather than technical specs (disclaimer: I don't have the ZX1, I'm just researching).

24bit is not just about the loudest sound vs the quietest one (dynamic range).....in fact, it is physically impossible for the human ear to hear / tolerate the dynamic range that 24 bit can provide (exceeding 140dB). Don't forget it also provides greater subtly / granularity within the range itself.
