Updated: HTC Mozart & Telstra–Battery Issues. “SOLVED”!
with 40 comments
Since the Mozart was released in Australia about 3 or 4 weeks ago, there has been a public uproar about the battery performance. Sometimes I haven’t been able to get 6 hours out of a fully charged battery with push email on.
I’ve been working with a technician from Telstra for the last 2 weeks debugging the issues. The root of the cause has come down to the way the Phone is configured to operate on the Next G network. By default, the phone uses the telstra.wap APN (Access Point Name) to connect you to the interwebs. Now the telstra.wap APN allows you to access internal telstra services like Mobile Data Usage & MyBill etc.
The “issue” isn’t one that “we” fully understand at the moment, it could be a configuration issue on the Telstra network or a software configuration change on the device. But Telstra understand the issue and are actively working to get a fix.
A workaround is available for all those who can’t wait for a ROM upgrade. All you need to do is add an APN in the “mobile network” configuration settings. The APN is “telstra.iph”.
Now this APN is specific to devices that require PUSH email & use a fair amount of data. The APN transparently proxies all your HTTP & HTTPS traffic over the Telstra network and improves the battery life 300%! I went from 6 hours to over 24 hours battery life.
To set the APN, go to Settings > mobile network. Scroll right to the bottom and click “add apn”. In the APN box, type “telstra.iph” and click the tick icon in the Application Bar.
Now, this is by NO means a permanent fix. What this does is provide a temporary solution for us while Telstra & HTC work on a fix.
The only “issue” with hard setting this APN, you can no longer get to the “My Bill” part of the Telstra Portal, you can still see “my data usage” and everything else.
Update: While hard setting the APN fixes the battery issue. It appears it stops people from purchasing apps via your Telstra bill. This is because the default proxy inserts billing identifiers as headers when you click “buy” via the Marketplace app on your phone. Now you”re using a DIFFERENT http server (the iPhone specific ones), which don”t know about the Windows Phone marketplace headers. To get around this, click the “change payment method” link before you click the buy button. This will give you the option of registering a new credit card.
Best Regards
USA using Mozart
Ok, I'm using a Telstra Mozart with an AT&T SIM card. Will this work for me? Usually if I change the APN I lose my service.
I have flashed the TMob_AT ROM by Ansar
Thanks for posting a 4 month out of date fix for a SPECIFIC issue only on TELSTRA to do with their APN, which was fixed months ago.
This post is totally useless and in fact incorrect as was resolved in December.
If anyone changes their APN because of this post, they are idiots.

No, don't change it, you are not using Telstras network, and if you are they fixed it months ago.
I really have no idea why the OP pasted it here, pure stupity.
It was regarding an issue with the TELSTRA NETWORK NOT THE PHONE.
Do not use these settings if you are not in australia and on telstra. It will not work anywhere else in the world, and it has been resolved locally. Does not help in Aus any more either.
@OP [original poster] does your phone work with that APN change? probably not! while your enthusiasm is valued, misinformation is not! Test before you post!
I've found a few new dial codes in the Rogers ROM following the Portico update. Here they are:
Note: All of these codes launch a sub section of the "extras+info" application through its GUID (2377fe1b-c10f-47da-92f3-fc517345a3c0)
Field Test
Code: ##3282# (or ##3282 + call)
Description: This one's not new, offers some statistics on radio. The settings also allow you to change a few things (such as network type, SMS limits, ENS and CMAS RMT).
Component: FTDComponent.dll
Color Variant + Life Time Counter
Code: ##634#
Description: Also not new... Displays the multivariant color (my value is null but yours might be displayed) and life timer. It reads that info from the registry ("Software\OEM\Nokia\Multivariant\Color" and "Software\OEM\Nokia\lifetimecounter").
Component: ColorVariant.dll
Silent Installer Component (no actual title - found a reference to "TestUI" so this may simply be a test)
Code: ##4678255#
Description: Mine does nothing at this time but the code seems to indicate that it monitors for provxml files. The monitoring is actually done by the SilentInstallerServiceAgent (SilentInstallerServiceAgent.dll). It monitors for registry entries pointing to physical provxml files at "SOFTWARE\OEM\Nokia\SIAgent\Multivariant" and "SOFTWARE\OEM\Nokia\SIAgent\Tier3". It also monitors the physical folder "C:\Programs\CommonFiles\OEM\Public\PreloadedApps\tier3Apps". When new provxml files are detected, it executes them (I haven't seen any indication so far that it'll do anything besides file copy instructions).
Component: SilentInstallerComponent.dll
extras+info (nothing displayed)
Code: *#07# or ##07#
Description: It gives a completely blank screen. The code is purposely written to keep all elements on the main page to a "Collapse" visibility (meaning hidden). But all the information that would be normally displayed when launching the "extras+info" application is in fact populated.
Component: Regulatory.dll
There's one last dial code that is in theory coded into the phone but the ROM doesn't trigger the action (it's not part of the OS support dial strings):
Product Support Tool (no actual title)
Code: N/A (can possibly be launched through an NFC tag if specifying a "DialString" argument with a of value "778" - I ordered some NFC tags to try it out)
Description: Because I haven't been able to run this app yet, I'm only speculating based on a quick code review... Allows you to view and modify some core cellular settings. You'll be prompted to enter an SPC (security code) before proceeding into certain (if not all) screens.
Component: ProductSupportTool.dll
Core cellular settings... do you think this might include band selection?

I was thinking the same thing. If it requires a security code, it must be important!
Anyone test these on an AT&T variant?

On my AT&T 920 all that does is show my phone number.

I have no idea. I'll need to look at the code a little more closely. The issue is that I can't run it right now; unless I find a way to enable Interop capabilities for third party applications (or sign my app as a second party - OEM - application). Or, if I get it to work with NFC tags (which apparently, were shipped yesterday)... And even if I launch the application with the NFC tags, I still need the password.
For each component I listed, they all have a native code back-end; the front-end is in .NET (non-obfuscated so very easy to interpret) but the back-end (where in some cases - such as the Product Support Tool - most of the code resides) is in C++ (harder to interpret). The Product Support Tool reads "items" from the C++ dll and populates a key-value type list. I'll need to disassemble and analyse the back-end C++ component to better understand what kind of items it's reading. The SPC code check is also done in here so I may be able to figure out the algorithm used to check the code and/or what static values it relies on to validate it.

That's interesting... Anyone else only get their phone numbers while doing ##3283# ? I've read a lot of people are able to enable 4G on some of the RM821 (international variant of the Lumia 920) through the settings in the "field test" component which means they get more than just their phone number.

778 is the code for PST, which should, in theory, allow you to modify settings related to the radios. I entered ##778+call and got a "Service tools" menu to open, but there is nothing available to select.

If I dial ##778 and call, it actually places a call.

Odd. Have you updated your device?
Code for MDN?
Hi,
Can anyone help with a code to change MDN? I've got the wrong one from a temporary sim used when setting up the phone. And now I can't change it. It's annoying as this number is carried through to the main dialler.
Thanks!

I must have pressed something wrong, or spaced, it works on mine too.
Following 1308 update, it appears ##3282 +call no longer works for field test.
Anyone confirm?

confirmed here too. I've seen posted a few other places. I've tried different variations and I can't get it to work. It come up with a screen that shows ussd and then my number or says something went wrong. Would like this back or find another way to toggle lte.

Nokia tells me to ask AT&T and AT&T tells me to ask Nokia. I had both techs on the line, but neither one knew anything about the codes or why we couldn't disable LTE from Cellular settings. Thinking of flashing a different firmware if that lets you control the LTE. I looked into the the development section a little, but not sure yet if that is a solution.
Am I understanding it correctly that value in ##634# Color Variant + Life Counter depends on Registry file, so if you flash a firmware for Red unit, Color Variant will say Red and if yellow it will say yellow.
Is this right?
So basically the phone depends on Product Code as every firmware has different code.
I flashed back to the AT&T 1249 ROM so I could have the field test option back. Until there is a way to enable field test again, I guess I'll stick with this. I looked at the other threads here, but there doesn't seem to be a way to flash to another ROM and have it work on AT&T.
Duds another solution???? thats is a ****... i can't flash but the 4G LTE Works sooooo ban here.
I'm trying to add MMS capability to my N1 on TDC Denmark, but after putting in my APN details and pressing "Save" I am returned to the APN list and it remains blank.
Previously I have had this same issue, but the carrier added it automatically so I didn't worry about it. This carrier does not for some reason.
Anyone know a fix?
Hi all, I have a Tmobile LG G5 that was working fine overall - I'm now visiting in Canada using the phone for roaming (data option enabled) and cellular options work fine but I don't receive data. Found out that I am missing the local carrier APNs and cannot add any - as soon as I put in the MCC and MNC and hit save the entries just disappear taking me back to the APN select page. has anyone come across the same issue? Is there a workaround? Thanks!
I'm bummed. I've had this Samsung S8+ since late last year. I didn't really want to root it but I wanted the native hotspot to work. I found out (on these forums) that it was as simple as editing the existing APN settings by adding "dun" to the APN type. I was able to do that previously and it worked beautifully. HOWEVER, I just got the #$&(^@ OREO update push from Sprint. Now my APN type settings reverted back to "default,mms". The APN type is NOT editable now. Therefore I am unable to add "dun" to the APN type settings. Now my native hotspot no longer works obviously. I have read in a couple of other places that the OREO update cannot be rolled back to a previous firmware version without putting the phone in a bootloop. I don't know that a rollback would even fix this problem. I was never really interested in rooting and installing a custom ROM. I simply wanted my native hotspot to work so I could use my laptop with an internet connection.
So am I screwed? Is there a workaround to edit these APN settings? The settings are not editable after this update. Any help would be greatly appreciated. Thanks.
Master lite oreo hotspot again
I have found a way on s8 plus sprint to use master lite again for native hotspot but must know msl number.

Thanks Pwallaker!
I did manage to get the native hotspot working again on the stock non-rooted OREO ROM. I don't know if this is just a fluke or what but here is what I did to edit the appropriate APN fields to re-enable the native hotspot (without subscription) on my Samsung S8+.
I entered my phone dialer and dialed ##3282# to view/edit data. I selected "edit" and put in the generic "000000" MSL code. Simply doing this did NOT enable me to edit the APNs. It only enabled a very limited edit that still would not let me edit the APN type fields. However, I immediately exited the data edit mode and then opened Shortcut Master Lite. I performed a search for LTEFunctionality using SML (SML could no longer get me in edit mode initially after the OREO update). I then launched "com.test.LTEFunctionality" (com.test.LTEFunctionality.LTEFunctionalityTest). I then scrolled down and selected "LTE APN Setting". This brings up two APNs named "APN2 EHRPD Internet" and "APN2 LTE Internet". Select the first APN and simply edit the field called "APN type". It will be already be populated with "default,mms". Simply select that field to edit and place ",dun" at the end of that string. Back out and repeat the same for the second APN. Exit SML when done. This is what worked for me with this new OREO release on SPRINT for the SM-G955U. I don't know if it makes a difference but I have the developer options enabled on my stock S8+. Good luck. YMMV!
