[HTC Sensation] Electriccars:
Hey guys, so I'm having a really odd issue with my batteries.

When I'm charging any of them they go to 60-70% really fast and then slow down to a crawl. Then if I reboot at that point it says it's full! WTH?

I changed ROMs, bought a new battery, wiped Battery stats multiple times, it still happens! It even seems to do it on different chargers. (Though I'm not 100% sure about the chargers)

And my sister who's running a totally different setup on her Sensation (we share batteries) reported she was experiencing similar issues using our portable charger as well. I don't know what's going on. :(

Any ideas? It's really annoying.
[HTC Sensation] rzr86:
there is nothing wrong

htc's issue in his devices when rooting then

i have also percentage misreadings

nothing to afraid

also wipe battery stats is just a myth
[HTC Sensation] Electriccars:
But I've had the phone for over a year and I've never noticed it before? :-\
[HTC Sensation] rzr86:
most users reported that thing after rooting their device

some said that it is htc's issue and it is still unfixable

it happened to me too

maybe it doesn't happen immediately

i don't know mate
[HTC Sensation] Electriccars:
Hmm. Okay, thanks. I guess it's not THAT big a deal if many are experiencing the same. Thanks! :)

I didn't see anyone mention about this here so I thought I post about it in case someone is wondering or is searching about it in the future.

For anyone that is an audiophile or just wants better audio... I have tried a USB DAC with our Xperia Z1 and it works great! As usual you need a USB OTG cable and plug directly to the DAC (or DAC/AMP combo). The USB port does output enough current to power the DAC and even charge it (a little... I don't think the Z1 outputs the full 500mA). Android volume controls also work and it controls it. All audio goes through the DAC and no additional software is needed. I even tried it on CyanogenMod 11 when I had it installed briefly, works just the same!

In my attached pic, the DAC Amp combo is the iBasso D2+ Hj Boa along with Audio-Technica ATH-M50 Headphones. It shouldn't be limited to this DAC. Once you have DAC support confirmation it should generally work with any driverless USB DAC.

And yes the DAC sounds way better than the built in audio. The built in audio chip is okay... but there's no life/fidelity in the audio. And no amount of equalizer can fix that.

Must be a pain in the ass to carry around and those flaps make it worse.
[Xperia Z1 General] TurdWiper:
Good to know
[Xperia Z1 General] raginginferno:
Carrying around isn't that bad... you can jam everything into a large pocket. This is more for a table setup, like if you are sitting at a desk for work or traveling on a plane. And yes the flaps kinda suck... the downsides of waterproof.

I actually don't use this setup very often. I also have the new NW-F886 Walkman which already has a really DAC built in. I usually have that hooked up to a portable amp. Using the USB DAC/AMP on android is a fun test I like to do whenever I get a new phone. It's just good info for anyone that wants better audio! :laugh:
[Xperia Z1 General] bahathir:
I already posted my comment about the USB DAC (iBasso D10, Cobra) in this thread, post #37 :)

http://xdaforums.com/showthread.php?t=2497518&page=4

I was very happy to hear to sound from my DAC, as soon I plugged it to the Z1, as soon I got it, Sept 2013. :)

iBasso D10 has feature to disable charging from USB. which may extend the Z1's battery life.

I recommend to use a right angled (L) USB OTG cable. and it fits much better or securely than the straight USB OTG cable.

Thank you.
[Xperia Z1 General] raginginferno:
Another USB DAC user :good:

Actually I am using a right angle connector in the pic but my case actually gets in the way of it. I think the one I have is too big... it's a DIY version of the micro usb connector so it maybe bigger than normal ones.
[Xperia Z1 General] bahathir:
I see. I am using generic OTG USB (F) and generic standard Mini USB cable, and I don't have any problem when using it, with the Z1 in soft casing.

Eventhough the digital audio stream is not 'bit perfect', ie, sound signal is mixed and resampled to 48kHz, but, it is enough to enjoy most of it. :)

As I mentioned in the other thread, I only listen to lectures and talk shows or podcasts, which most of them are sampled at 22kHz AAC (24kbps bitrate), so it the resampling effect/artifact is not significant.

The good thing to use DAC+headphone amp, we can get better dynamic range and able to drives headphones/earphones/IEMs at optimum level.

Thank you.
[Xperia Z1 General] hikashi:
So now Z2 is out and it specifically mentioned it support USB DAC but not with Z1.

I have a usb DAC personally (Fiio E07k) and it works with xperia Z1 with usb micro to mini cable without any modification to the software.

Any difference between them Z1 and Z2 in terms of functionality?
[Xperia Z1 General] Noxien:
I was actually thinking about picking up a USB Dac I am still using my home made CMoy amp with a Burr Brown OPA 2132 P was thinking it might be time to upgrade good know know the USB Dacs work with the Z1
[Xperia Z1 General] ra97or:
Have been doing this since the Z1 came out. Now it is my reference portable system, sounds better than AK120 at a fraction of it's price.

The near fatal flaw of lack of memory space is getting fixed by 128GB microSD, I am happy.
[Xperia Z1 General] XP-Audio:
Z2 and T2 USB Audio support

As product owner for USB Audio in the Z2, I would like to explain about our USB support.

In the 2013 mid- and high-end products (Z, ZL, ZR, Tablet Z, Z Ultra, Z1, Z1 Compact) we support USB Audio from the Android Audio framework, which means that all audio is resampled to 48kHz/16 bits, and mixed in with notifications etc. This means that we have "bit-perfect" reproduction only for tracks with this sample rate originally (and such are not very common) and turn off all system sounds and all sound enhancements (and even then, I cannot guarantee that we are 100% bit-perfect).

In Z2 and T2, however, we have introduced a new mode, "High-res audio over USB", where the audio stream is sent directly to USB after unpacking/decoding (actually, when selected, this applies to all audio data, no only high-res, so internally it is called "Direct" mode).

The only exception is if a DAC does not support a particular sample rate, in which case it is sent to the audio framework in the previous manner - for instance, some DAC's which support 96kHz do not support 88.2kHz, strangely enough.

Anyway, in this feature we support 44.1kHz, 48KHz, 88.2kHz, and 96kHz in either 16 or 24bits using USB Audio Class 1, and also 192kHz and 176.4kHz using USB Audio Class 2 in Asynchronous mode. The file formats can be either WAV or FLAC for lossless compression, or MP3 or AAC (which decompresses to either 44.1 or 48kHz at 16bits). I guess other generic Android audio formats should work too but they are not in scope since I have never seen these at download stores.

One caveat with 192 and 176.4kHz files is that the Android downsampler does not handle more than 96kHz, so if you get such files, they will only play in High-res mode to a capable DAC, not in any other circumstances.

In this mode, since we bypass the mixer, ring signals and notifications etc are not passed to the USB DAC. If you want these in headphones connected to a portable DAC, you will need to turn off HigH-res mode and everything will then work as in the 2013 products.

I will be present in this forum for questions and problem reports when these devices are released. Currently we are testing with a limited number of DAC' and I will post a list of these soon.
[Xperia Z1 General] hikashi:
Wow. Very insightful. Thanks.

One more thing, will this High Res over USB feature carry forward to the Z1? Or it is a new hardware feature.
[Xperia Z1 General] XP-Audio:
I cannot comment on unreleased features, however, this feature is not dependent on the specific hardware in Z2. Generally, backporting new features into older products is always a question of resources.
[Xperia Z1 General] rency_0722:
Well that's a good point. But how LG G2 (which is marketed to play Hi-Res audio) differs from the Z1?

For the "High-Res Audio over USB" mode on Z2, well, it is still unsure whether Sony will be porting this into the Z1 with the KK upgrade. Right now, what's clear is that USB DAC is supported but with limited audio sampling and frequency.
[Xperia Z1 General] gooru2:
Tested with Fiio e07. Working great.
[Xperia Z1 General] Leungerz:
Compatibility with Z1

Hey there, firstly I have to say I am amazed at the fact I found something online relating Z1's with M50s, so thank you for opening this thread. My question might be a bit off tangent, but I'm currently looking at buying some M50s, and Im sure you know as an Xperia user, the headphone glitch is one of the most frustrating parts about the phone despite it being an amazing device. Do your M50s work with your phone, when plugging them in the standard jack?
[Xperia Z1 General] raginginferno:
Headphones glitch? The only I can think of is if you use like iphone headphones it won't work because it uses the other mic/heaphone standard than the xperias do... is that what you are refering to.

In anycase what you are asking is not related. With any android phone, if you plug in any sort of regular (no mic) headphones the phone audio will go through the heaphones and the voice will be picked up by the mic on the phone. In the Z1 case, the bottom where the external speaker is. So it works just fine (I tested just in case). So if you are going to use it with voice calls, the phone cannot be on your pocket.

Btw side note, I am on cyanogenmod mod (it shouldn't make a difference) but unfortunately cyanogenmod no longer supports USB DAC. Kali mentioned that it screwed up the dock charger so he disabled usb dac support :(
[Xperia Z1 General] Leungerz:
z1 headphone comparability

Thanks for the quick reply. I think I get your point, simplifying my question; I just wanna know if when you plug in your M50 standard headset in the normal jack at the top of the phone, audio plays properly. Sorry for the confusion lol. Also when did you get your z1?
[Xperia Z1 General] raginginferno:
LOL. That's a lot more simple question. Yes the Ath-M50 works just fine with the Z1 through the heaphone jack.

I got my Z1 in December. One of the first batches available in Canada.
[Xperia Z1 General] ali87:
thank you for the great explanation! this info is exactly what I was looking for. Does this also mean that I can send any audio out through usb? for example, Google Play Music streaming app, will the audio stream to my car's usb port? or does it only support locally saved files on the phone? Thanks!
[Xperia Z1 General] ferx1:
Could you please contact me at mendozas@gmail.com?

I need to know how to enable audio USB via Sony DAC in my Z2 ; I work in Sony too

Thanks
[Xperia Z1 General] KBEscalona:
I guess this will work on my Logitech Audio Hub. Thanks.
[Xperia Z1 General] gewgaw:
Hello, thank you for such an insightful post.

I wonder though how well does the XZ1 handle the M50s. I have been wanting to purchase a set myself but the audio in my XZ1 is disappointing although I hear it is a general issue, the volume is a little lower than expected.

How does you XZ1 drive the M50s? How does it perform when going through the USB DAC?

Any pictures of your set up would be appreciated as well.

Thanks and let's keep this "underdog" of a phone alive!
[Xperia Z1 General] raginginferno:
For me personally it's hard to say now. My original post was way back when the phone first came out. Now I've left stock firmware ages ago and am now running Cyanogenmod. Cyanogenmod has also lost USB DAC support... due to the fact that when the magnetic charge cable is connected, there's no sound at so the FXP team had to disable USB DAC in order for it to work correctly...

So with Cyanogenmod, volume is actually worse than stock. So I had to add this volume boost mod:

http://xdaforums.com/showthread.php?t=2476498

With this mod and Cyanogen, I'd say the Z1 can drive the M50s headphones just fine. The volume boost does help I believe. M50s are not a hard headphone to drive but it's harder than normal earbuds.

How does it sound? Um.... good I guess. It's a phone... not much I can say. I don't even have test it, I know a decent DAC with a portable amp will automatically sound better than the Z1. I've tested back when I was able to and there was just so much for life in the music when you have a nice DAC Amp attached to it.
[Xperia Z1 General] gewgaw:
Yeah I see what you mean. I briefly used CM for a little while but it was "too nightly" for my taste so I went back to stock. With the recent Walkman updates it is visually awesome. I can't think of any other better Music Player besides iTunes for iOS. But maybe this is just a personal opinion or taste. Sound quality is O.K. but the volume is still lacking I think. I just recently listened to both a Note 3 and a G3 and man did they kick ass in Volume dept. Don't know why Sony made it so low, waterproofing maybe?

Fiio recently launched the E18 specifically designed for Smartphones. I will give it a try when I get the chance but if only the Visuals of Walkman matched the Volume Level.

thanks!
[Xperia Z1 General] raginginferno:
Well finally Z1 is part of the stable snapshots builds now, so we have more stability. You can get the walkman app back in to cyanogen, search through the forums for that. If you want the walkman widget you have to use the sony launcher as apposed to the cyanogenmod launcher. So FYI is you want to go back to cyanogenmod.

But try the sound mod I mentioned. It only changes a few values in one settings file. No actual major file swaps. It may push the headphones volume to the levels you may actually want. I only picked the "boosted" level, the other "higher" volume choices are way too distorted.

hello. sorry for this necro-post here, but i could use some help. :(

i have purchased 2 different DAC units and a half-dozen different OTG cables by now... for the life of me, i can't figure out how to get any audio through one of these things. i am on the Sony Xperia Z1(C6903) and really really need a DAC to work. my headphones jack is broken. T_T

can someone help me figure what to do?
[Xperia Z1 General] OmegaRED^:
What DAC's are you using?
[Xperia Z1 General] sk74261700027:
i have tried both version of the, "HiFiMeDIY Sabre Android USB DAC, Android Digital to Analog Audio Converter ES9023+PCM2706".

the one that needs an OTG cable. and then there is one that connects directly to micro-USB. they SHOULD work. the green light is lit up, but all audio still comes through the phones main speaker.

the OTG cables works fine, because i can read USB mass storage through it. i have also tried to enable the option through developers options for routing audio through the USB, but it is enabled by default. so then i tried disabling any other USB options... like fast charge, MTP and diagnostics mode.
[Xperia Z1 General] OmegaRED^:
Odd i have used 3 audio dac's with no problems.

even my corsiar headphones work perfectly.

Dear SONY developer,

recently I bought SONY PHA-2A USB-DAC amplify and trying to use it to connect my old Xperia X1Z (btw I have Xperia I III but it just doesn’t have the good old Xperia Equalizer, the Dolby Atmos is just meh :/) and fulfill my Dream: Xperia sound effects + DAC & amplify with a 4.4mm balanced port. The most important part is THE ‘Xperia equalizer’, cus I’ve been using it since almost a decade back when it came out on Sony Ericsson Phones. The SONY equalizer just gives an impressive experience especially with its ‘clear bass’ function. And when I am trying to use the ‘Xperia equalizer’ for the PHA-2A, I am kind heart broken, seems the sound effect from equalizer just bypass the digital signal and doesn’t add to the output for the PHA-2A, the sound quality is still good but just without my favorite ‘clear bass’ etc -.-

So I’m desperately to find a solution. checked a lot of tech websites and also have tried at least 15 different 3rd part equalizer app, most of them work for the PHA-2A, but simply no one can match the fantastic awesome clear bass effect as Xperia Equalizer could offer.

Is it possible to fix this? I'm quite sure its just a software issue since other equalizer app just work on the USB DAC. I'm really desperate to find a solution! Many thanks!!!
[Nexus 4 Q&A, Help & Troubleshooting] Monotoko:
I find the virtual buttons a bit of a nuisance, I would much rather use gestures. I originally wanted to hide them only on my home screen, but it seems it's all or nothing with qemu.hw.mainkeys in build.prop.

I'm fine getting rid of them, however I'm wondering if there is a gesture system I can have instead, for example a swipe from bottom takes me to the home screen?

Edit: I'm on rooted stock 4.3.
[Nexus 4 Q&A, Help & Troubleshooting] 1Chef:
I'm using cataclysm ROM which has a unique feature which fades out the buttons after ten seconds in any app. Other wise I think there's an xposed module that can have swipes to navigate.View attachment 2557296

Thanks man, turns out I was Googling for the wrong thing - once I figured out that they were called navigation bars I came across an app called " GMD Auto Hide Soft Keys" for rooted devices. (For future people)

I'd rather keep with rooted stock for now but I will be sure to keep an eye on it for when I decide to dabble in roms.
