If I recall correctly, I asked pretty much the same question here in this thread.

Answer I got was that the mojo is designed to work ok as a desktop dac, if the battery is full and the charger is connected, mojo takes only the amount of energy needed to work and it should not be that hot, this was the answer from Rob Watts himself.

So keeping the mojo connected to the charger when the battery is full is ok, in my experience the charging light does change (which to me indicates is charging) but the mojo doesn't get hot.

If you search this thread you will find the exact answer.

That makes total sense.
 
There's obviously a lot of very proud new parents here that would do anything to protect their new baby!
 
Just to be on the safe side, I will try to run in powered mode only after it's fully charged.  Probably overprotective since the battery is supposed to be high temperature tolerant, but I will be gentle with it for a while at least!

Posted a bit more info on my Mojo/Z5C combination here if anyone interested.  http://www.head-fi.org/t/779909/sony-xperia-z5-range-audio-quality/315#post_12217394

Hey there,

20 hours in I couldn't be happier with mojo...well other than the fact, that I have to keep my screen on all time, but that seems to be due to USB audio player pro, hope this will get fixed in later versions.
Other question about the player, what volume setting do you use for USBAPP?
I experienced full volume resulted in higher noise floor... Especially experienced this with a 24/96 version of Kill em All and a 24/192 version of Bayou County...with more contemporary recordings it wasn't noticeable.

@simonm
Did you pull the trigger on phones already? I am very happy with the Audio Technica ath w1000x.
scored them for 305€ on black Friday... So they are even budget friendly!
Some argue they lack subbass, but I don't miss anything! Maybe If you only listen to heavy hip hop and Drum and bass there are better phones for the money... But handmade music sounds awesome... Vocals are very special with these phones and Mojo... I never felt closed to Norah Jones

Likely down to your phone. When I used Mojo with my S6/Note4 I got audio glitches with screen off but not now I'm using a Sony Z5 compact. Works perfectly.

Mojo, like Hugo, has been designed so that you can have the charger plugged in constantly. So on a desktop charge and run it at the same time. Once its fully charged, the charger will just supply enough current to balance Mojo's current draw, so no net current from the battery.

Incidentally:
 

   
The colour without the charger connected is the one to watch (fully charged is blue then green, yellow down to red, flashing red means 10 minutes left).

Yeah I fear you're correct. well maybe the guys from USBAPP will figure out a way, since there are a lot usb options... But none works for me, yet.
Other question, is there any hope, that the Tidal integration is going to be improved? Like having access to the same navigation like in Tidal, with options to go back after you chose an album

Also I am looking for a case for mojo... And still a USB cable for portable use... Something like the moon audio silver dragon form fit... For a realistic price.

 

[audi0nick128]

Damn... Need to share the impressions of an old favorite.
Against Me! The acoustic Tape is by no means an audiophile recording... BUT mojo paired with ATH w1000x brings you right in the middle...

Some random ramblings and impressions:
Initially I really didn't like the HD800 with the Mojo but (whether the Mojo burned in, which I was told it did not require, or it was the crappy bestbuy 1/8 adaptor I was initially using and changed to the cardas 1/8 adaptor and soon to have the Norne Audio xlr to SE adaptor but), with a little of EQing, the HD800 sounds fabulous. The HD800 does sound more dynamic and full with the Liquid Carbon, but there is a greater transparency and unique presentation that the Mojo alone provides that is very enjoyable and addictive. 
The longer I have the Mojo, the more I'm appreciating this little wonder. 
 
The Dac 19 has greater macrodynamics but the Mojo seems to excel at microdynamics. While the Dac 19 has more overall bass quantity and authority, the Mojo while it lacks the lower bass that gives the music weight, instead has a slight mid and upper bass and upper mid/lower treble emphasis that makes it sound more lively, forward and engaging that the Dac 19.
For the same reason, the Mojo does sound slightly thinner and brighter compared to the Dac 19 but I also feel the Mojo digs deeper in the recording pulling out more detail.

  Thank you all so much for your replies re the OTG cable, I think I might try with a friend's phone and see what happens.
 
Another question I had was:
 
* If I leave my charger plugged into the unit, will the unit be powered by my charger and stop using the battery after it's charged?  I would like to use this at home a lot but I'm worried that the charger is constantly trying to charge the battery.
 
Thanks in advance

Mr Rob Watts explained how the charging circuit works when the Mojo is left plugged in. I added it to the Mojo Issue Solutions thread.
 
Rob Watts explanation was post 4596 last time I looked. I didn't note down the page number. This is what he said exactly:
 
"Just to clarify. Charging is automatic. If you are playing and charging at the same time, with a fully charged battery, the charger will supply enough current to balance the consumption used by Mojo, so no net current into the battery. If its fully charged and the unit is off, the charger will go off. The charger will re charge automatically when the battery voltage falls to 8.2v (off at 8.4v) so keeping the charger connected will ensure a full charge."

Yeah, but make sure to not listen to Mojo while charging it, and that is my point. The fact that Mojo doesn't use supplied current on the charger circuitry when plugged in, but using the battery instead. Long time ago I heard that it is very bad for a battery to be charging and depleting at the same time as the battery will have it life reduced "considerably". I am not too sure about the nowadays technology. But to me, better safe than sorry, because Mojo get 2x hotter when charging and playing at the same time. But that is me. Though anyone can do what they want, after all the battery is replaceable

I understand the desire to protect our new babies, and historically have been in the OCD camp about things like this. However, some of us think nothing about spending $100 on a small cable for better convenience or pairing with a specially purchased $500 DAP. Given that mindset, it's my opinion now that I will just use my Mojo as conveniently as possible, which probably means leaving it charging all the time while in my home system. How much can it cost to replace the battery, anyway? Don't stress...listen more.

What you have said does not make sense. You clearly don't understand the explanation Mr Rob Watts gave of the charging circuit.
 
Undoubtably the unit gets hot when charging and playing, but all power is from the power supplied to it. The battery will not draw power when charged up. The battery will not provide power to the unit when the charger is plugged in.
