Please tell us some basic information before asking for help:

  1. Model Name: Asus Rog 3

========================================

When I attach the charging cable to the phone it's charging, doesn't matter which port I use.

How can I activate passthrough charging/power which means the battery is not charging only the phone gets energy from the cable?

Or I misunderstood the reviews about the phone?

Comments

  • In my understanding passthrough power when your battery reaches to 100% the power adapter which is charging the battery will directly go to the phone automatically bypassing the 100% battery. So the battery will act as a UPS (uninterruptible power supply) which i'm using in my Desktop Computer when you switchoff the power line adapter the battery will kick-in and supply the phone.

  • What it does is that it only takes as much power as it needs to run the system. So if you're at 32% battery and enable passthrough power, then you will still have 32% when you stop gaming. The benefit with this mode is that it doesn't generate extra heat from charging the battery.

  • But how do you enable this on the phone?

    Where is the settings for this?

    Which port do I have to use?

    Do I have to use the bundled 30w charger?

  • Sorry, too fast, didn't read ;)

    If I'm not mistaking, this option will appear inside Game Genie while charging in a future update. Soonish

  • That's a promising feature for gamers.

  • Hi Bro, i just receive my ROG3 Global and to activate the Pass-through manually there is a 3 choices 80%-90%-100% the default is 100% that when its fully charge and 100% the Power Charger will go thru Phone without charging the battery to make the battery long last.

    To do this go to Settings -> Advanced -> Mobile Manger -> Power Master -> Battery Care -> at the Bottom select want you want me i just selected the 90% which is my battery now is 91% so it works it didn't charge the battery, PowerCharger Pass-through directly to the phone. I downloaded "Ampere" apps to confirm see below Screenshot. 

  • The settings of 80, 90% you are seeing is for device to stop charging the battery even if the charger is kept ON.


    Per moderator @Anders_ASUS below is how passthrough works...

    This feature will come in game genie app in near future updates...

    did you even tried? as for me it is the same from 91% i played PUBG almost an hour and when i unpluged the charger i still have 91% coz i set 90% limot. So as for me the same as pass-through coz it didnt charge my battery it is good for me.


    Also not all moderator know the answer i create a thread and asking if the Mobile Dock from ROG1 2018 is compatible with ROG 3 he said it is not coz the thickness he said but when my ROG3 arrive i tried docking it in my Mobile Dock it is fitted and workinb 100%.

    You seemed to be misunderstood the pass through vs limiter. LIMITER is when the charger stop charging the phone in 80%, 90% or 100% but it doesn't mean that the battery is not getting power from the charger when you are playing. It still the battery who gives power for the phone and the charger is still giving power for the battery and while you are playing it drains the battery but on a contrary the charger is still charging the battery so that's why its still 90%. PASS THROUGH is when the charger is "DIRECTLY" giving the power for the phone so the battery won't be drain and being charged by the charger to reduce heating. Just imagine a laptop that doesn't have a battery but you can use it while charging because the adapter is directly giving the laptop a power. And its the same concept for the pass through.

  • i know what limiter is and pass-through power but did you see my screenshot ampere app? the charger is not giving power to the battery to maintain its % but the phone to be alive when plugged by adapter my explaination is base on my experience not base on theory.

    When using Ampere app without charger plug you can see negative ampere means its consuming power on the battery but in my experience its not.

  • Your reasoning with ampere app numbers sounds good and exciting. So the passthru feature working in disguise of charging limit, when charging limit is set to 80% or 90% or 100% and it won't work when battery level is less than 80%.


    Maybe once feature is rolled out to appear in game genie, it would support at all battery levels.
