iBasso DX300MAX

Someone already mentioned it on headfi

Some pictures.

Actually, that was me who asked Dmitry to develop PCM->DSD256 in Neutron and helped to test it on R8 and DX300MAX (Dmitry unfortunately has only DX220).
After we found R8 does DSD256 real-time conversion without stuttering and DX300MAX does well only with switched screen on, Neutron stays active, I did simple CPU clock check for both, R8 and MAX3 and found S660 on MAX capped between 633 and 1401 MHz while S660 on R8 ranged between 1843 and 2208 MHz.
After that I had mail conversation with Paul suggesting to release a kernel with higher CPU clock, but he stopped to respond me after a while.

Paul’s very first reply was referring to bad temperatures and to much worse battery life for uncapped CPU. If you have a chance (And time of course) can you test uncapped CPUs MAX3 in normal usage scenarios (e.g Mango), will battery life drop significantly?

Thanks,
Roman

No worries, thanks for joining.

It would be nice for discussions to stay over here as much as possible.
Head-fi get too much traffic from member generated posts and knowledge sharing yet treat those members like dirt.
They seem to forget that without members they would have no sponsers to keep their marketing business erm sorry forum going.

SS is only a little better than Titanium in heat dissipation. The best of it should be coming from Aluminum Lol !! But it is exciting to hear that it is possible to click it higher

Make your DX300MAX faster ! and more battery life !

Uninstalling around 50 apps they aren't removed from the DX300MAX rather uninstalled for the default user i.e. us
They can be reinstalled, they also come back after a factory reset.

You will need to enable Developer Options
(clicking on 'Build number' in Settings, System and About device a good few times)

You will need to enable usb debugging in developer options
You will need ADB on your computer to connect to a console session on your DX300MAX via USB

Hello,

Thank you very much for the useful info here.

Referencing this post on the DX320 thread, I tried to debloat on the DX300MAX Ti with Android11 (FW2.01).

I made some modifications as follows.
Deleted commands
in the 'Various Bloat' section
- pm uninstall -k --user 0 com.qualcomm.qti.auth.fidocryptoservice
in the 'Markets' section
- pm uninstall -k --user 0 com.snappea
** These are not installed on the FW2.01.

Added command in the 'Markets' section
- pm uninstall -k --user 0 com.wandoujia.phoenix2
** This Chinese app store '豌豆荚' app is installed on the FW2.01, instead of SnapPea.

Below is the command list modified for the FW2.01.

The market apps APKPure and '豌豆荚' were deleted by the commands above, but strangely they were automatically re-installed after the reboot. So I re-deleted them by manual (Android Settings-->Apps & notifications-->SEE ALL APPS-->APKPure/'豌豆荚'-->UNINSTALL) to avoid re-installing.

I skipped the following commands because I need them.
Skipped commands
in the 'Launcher' section
- pm uninstall -k --user 0 com.ibasso.launcher3

- pm uninstall -k --user 0 com.google.android.gsf.login
So far it works fine!
