Hello, everyone.
I just got my XZ2 but when I charge it, it only displays that the phone is charging. Not quick charging. What does your phone say? Thank you!!
Sorry phones never show quick charging so don't worry
Maybe what you meant is a "Charging Rapidly" message?
It's not just not saying quick charging... it isn't quick charging from what I can tell. A full charge takes me 2h 15 min, though much of it is because it slows down to 5% per 15 minutes once it is above 70% or so. But the maximum power draw I've measured (with screen off) is 12 watts. That's basically 5V 2A charging, which we've had for a long time now. A Xiaomi Mi 6 for example draws 19 watts, and is fully charged in 1h 15 min, despite having a bigger battery. I believe Sony isn't quick charging to prolong battery life, which usually is a good thing. I just wish there was a manual way to tell the phone to quick charge, when you know you don't have a lot of time to top it up.
QC3.0 is working fine... we have Voltage from 5.2 to 8.8V which is normal.
2h15min is a complete normal duration for charging. We have Qnovo Charging Technologie which slows it down. but it will greatly enhance longetivity.
I've tested charging here.
I'm ok with the slow charging, except there are times where you don't have access to a power socket for long. Say at an airport. Or you are about to leave home and find out the battery is almost dead. In those situations I just want to hammer the battery... and that that is possible is obvious when you look at the competition. They won't last as long, but if you could activate quick charge in emergency situations that would be great.
Also, that's a great posting. Thank you!
I upgraded from Z5, so quick charge on XZ2 is pretty fast!
It run with quick charge but just dont like the other.. i think sony only use around 80% capable of qualcom quick charge
When I had an HTC 10, the battery ran out faster after it was charged using the quick charger.
With XZ2 I just use the original 1.5A charger, nothing to complain about battery life.

I can also confirm this... Its working as it should... this charges faster than my old XZ.... Also You could consider a power bank, you can pick up a 4k power bank for about £10 /$15
IMO, Ide rather my battery lasted 2 or even 3 years and buy a power bank than have battery problems in 12_18 mnths, but I do agree with you ... it confused me at first, and It could say "quick charge" or something similar
Options have 50 char limit.. So here are longer descriptions:
- Yes. Fast charging is always ON
- Never. My battery lasts the whole day and I (slowly) charge it overnight. And I am either not in a hurry or good at planning my charging time
- Sometimes. I turn it ON only when I need it
- I don't care or know anything about it. I use default settings
Is there an option to turn it off? I haven't seen it. But anyway i use my old s3 charger for all my devices. I don't trust fast chargers. They kill batteries.
Slow charge really isn't that slow.

Regarding fast changing killing batteries the charger provides a voltage to the phone, the power management controller monitors battery voltage and temperature , I would assume these have limits and will take control if outside of range in a similar way to throttling cpu frequencies when it gets too hot.

Where did you find this setting?
I'm using "bad" cables for show charging but being able to limit the current and the charging state without root, like on Sony smartphones, would be great

The option is in Device Care > Battery > Settings
Personally I leave fast charge turned on and use a bunch of different chargers with the phone, I just have Battery charge limit set to stop charging at either 80% or 90% (depending on when I think I'll be next able to charge) and try to start changing between 20% and 40%.

Using "bad" or cheap cables is really not the best idea, they often don't meet the USB C spec and could damage your device. Try to stick to high quality but low current chargers (Like old phone chargers) or disable Fast charging as previously mentioned.

Strange. My n9600 doesn't have that. I got device maintenance and there's some battery saving options in there but no fast charge option. Oh well the s3 charger works for me.
Edit - nvm found it.

It's rooted. I did come up with a solution using the Automate app and a smart plug a little while back but only worked if you're charging from the charger that's plugged into the smart plug.
Yeah okay this 2 ways are well known
Thanks for the fast reply ^^
I was already questioning my eyesight. You know, Samsung UI and not finding an specific setting in menu could happen even after years I think ^^
I charge when I want, as fast as I want. I leave it on the charger overnight, everynight. Have done it this way for years and will continue to do so. Never seen I'll side effects from doing it this way. I have too much of a life to monitor my charging speed and make sure I'm next to the charger to stop it at 80%. I like waking up to 100% and using it as I see fit through the day. YMMV
Fast charging is set to ON by default straight out of the box. So youll think samsung has taken this to consideration.
Personally, i keep this off when charging with the orginal charger. I have an app called Battery Warner which alerts the user when over a set %. or if rooted it will stop charging and enable charging when it is under a %.
If i have plans to go out and the battery is low then ill throw it on fast charge.

My 2 cents:
I think Samsung doesn't care much if battery will remain healthy after 2 years. They care now to sell as much Notes as possible with the "Fast charging" marketing slogan.
That's why it's ON by default.
I never use fast charging as it will provide more harm than benefits to the battery health + I use a magisk module (Advanced Charging Controller) which have cooling mechanism and voltage monitoring and also battery temperature monitoring and this will also greatly increase the battery life on long term use.... since we got a non replaceable battery
Since I rooted my Note 9 on day 1 (I don't care about warranty) the first thing I did is I used Advanced Charging Controller and keeping my battery healthy for as long as maybe 4~6 years of usage

It does, but still the degradation is higher vs no fast charge.
on the topic: The first thing I did on my s7e was to turn off fast charging - the battery after 2.5 years is in a really great shape even after every day charging. The same I did on my note 9. Will use fast charge only if I am in real hurry and need a lot of battery fast. If the phone is changed every 2 year tho, it's not that big of a deal and everyone decides for himself.
Otherwise in most cases it's not needed to charge overnight as 0-100 without fast charging is 2h-2h and 10 minutes. As most charge from ~20%-100% it will take 1:40 to charge the phone. The overnight charge is if the phone is charging from the PC USB - the best way for battery longevity, but not really worth the hassle vs normal charger charging.
According to poll results: more than a half (or 2/3 depending how you will count) uses fast charging.
No, slow on cable and fast charge for wireless!
Photo's by Sully using SM-N960U
The high temperature is an enemy of the li-ion battery. The normal load on the cable drives the temperature to 30.5C. Fast charging on the cable tray at 34.5C. Fast wireless charge up to 37.8C. What better?
Never have and never will use "fast" cable charging. I dont wireless charge either.

so basically my phone stopped charging after two to three days because it would just charge slow but then charge fast again then charge slow again I don't know if it's the battery or the charge port but yeah that's what I'm trying to find out also whenever I did check the battery capacity it would say that it's at 2800 and then it would just say like in th system settings it would say Null Mah. If anyone knows what it could be it be nice to know and also best place to get replacement parts fast.
i have the same problem
Apparently its a common problem for Xiaoi Phone. Trash company. Chinese trap.
Did you finally find solution?
Limiting the battery charge to a fraction (70%-80%) of it's full capacity is a well known way to greatly extend the battery's charge capacity lifetime. There are several (root) apps created to automate this, that stop the phone from charging once a selected charge level is reached. Battery Charge Limit is one (https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002), ACCA is another (https://github.com/MatteCarra/AccA/). So far I have not been successful getting either of those to work with the ROG2. I was wondering if anybody has had any success with those apps or any other way to limit the battery charge on the ROG2?
The Rog phone 2 has its own function that lets you automatically stop charging.
But keep in mind this function is only useful if you are planing to keep the phone connected to a charger 24/7 then it's useful. Otherwise it's worthless if you disconnect your phone once it's 100% charged.
Battery also needs to discharge and recharge to keep it's capacity and function going. If you don't do this it can wear the battery out even if you stop charging at 70-80%.

Most of what you said is wrong.
The ASUS Power Master Battery Care feature slows and delays the charging but still charges to 100%. The feature is only useful if you have a regular charge schedule (which I don't, and DO mostly leave the phone on the charger) and even then, it's still charging to 100%. Repeatably charging a LiPo battery to 100% WILL decrease it's capacity significantly faster than if only partially charged. All phones already slow charging at high charge levels. There is no advantage to discharging the battery.

Did you ever know that even authority can be wrong in facts as well? I can confirm that battery feels alot better with discharge and charge than what it is with 100% all time or 70-80%.
How I can confirm is that I have a Microsoft surface Pro 4 and when I kept it on charger at 100% for a day or two the wear level jumped from 0% to 3% but when I discharged it and recharged it after some time then tear level on battery went back to 0% and capacity was back to its full capacity again. So discharge and recharge does not always wear the battery out. It actually makes battery feel better too.
So please don't always believe what internet and what authority States. Since on internet there is alot of false facts and authority gives alot of nonsense facts alot of times too.
Is it really wise to basically degrade your battery by 20% out of the box just so you can have 95% in 2 years? If anything, heat is the greatest factor for degradation. If you're that worried, just use a 2 Amp charger.

Yes, heat is a factor, but keeping the battery at 100% will degrade the battery faster regardless. If you simply do not need the additional 20% than there is no advantage to charging to 100%. My usage scenario is that the phone is plugged in a lot of the time and I very rarely need the full battery capacity. I've had several phone batteries bloat up under this scenario (and not using any fast charging).
When batteries degrade they don't stop at 80%. They generally keep degrading fairly rapidly. And you don't just lose capacity, as the battery degrades the internal resistance increases, which results in throttling and/or crashing.
BTW on some phones, ACCA will stop charging the battery when it reaches the desired charge level and run the phone entirely from external power.

Agreed. If manufacturers still offered replaceable batteries in their flagships, this would be somewhat of a moot point. When dealing with a sealed battery that is expensive and time consuming to replace, it's wise to do everything reasonable to protect the overall lifespan of it.
As for keeping it charged at 100%, I did that once and killed a battery in about 6 months. Not doing that one again.
Guys, it's so nice you are debating over the battery charging metaphysics but it does not help us solve the issue: our rooted phone can not be charged in a smart way using magisk+acc, ACCA or Battery Charge Limit.
Any ideas?
I'm facing issue with my Rog 2, my phone is not charging fast
1. I'm using 18w charger come with the phone to charge
2. I have used Xiaomi 2i power bank with 18w output to charge my phone (still not working)
3. I restart the phone on charging it goes down 36% to 29%
4. On charging when i restart the phone it goes 8% to 13%
5. I'm facing this problem from the yesterday
6. Double plus sign on battery icon as well as fast charging text on home screen is also not showing while charging
What is the issue please help anyone
Submit a bug report to acca and maybe at least someone starts caring for the ROG Phone. The reason why it doesnt work is simply because ASUS does its own stupid thing while charging (thats what happens when 100 OEMs cook their own soup, a mess).
About the battery health:
A battery keeps its best health when its charged between 25-75%, is kept below 30°C and charged as slow as possible. Thats why its wise to stop charging at 80% with a slow charger, especially when you have a big battery anyway that lasts for a day with 80% charge.

There is no programmatic way to internally control the charging process without root, however there are some (not as good) alternatives.
First there is an app Accubattery that will give you a notification when the battery reaches a given level, you have to then disconnect the charger manually.
A second way to do this would be to use a smart plug and control it with Tasker. Don't know if anyone has done this but it should be possible.
Another possibility that is not vailable yet would be a kickstarter project called BatteryPal. This is a charging cable that had a bluetooth interface built in to it that would control charging using an app on the phone.They arr saying it will be available March 2020, but who knows.
I'm facing the same situation here. I'm next to a charger most of the time, so I like to use slow charging and not going above 80%. I was used to have battery charge limit installed in all my devices, but found this is not working with the rog phone.
My rog Phone 2 global edition over heats while charging
has anyone found a way even with root? I've tried ACC and some other app but they all done work.
I've also just tried ACC and Battery Charge Limit, but neither worked. It looks like there is something that keeps overwriting the charge control file all the time and allows the battery to charge anyway. Battery Care was disabled while doing this.
I am rooted, so I am able to test any potential solution.
Someone posted on r/rogphone2 a solution for this:
https://www.reddit.com/r/ROGphone2/comments/ev0put/hows_this_it_never_reaches_100/
I've just tested it and it works for me.
Does anyone know of a legit charging adapter that isnt fastcharge and doesnt damage the phone or gets damaged itself after a while? I want to charge my phone without fastcharge but cant find a good charger

Though I may be wrong, I think you need the 30W charger for that. 6,000mAh battery is quite a handful and 18W may not juice it up as fast as you want.

Well, there is obviously a problem.
There are battery apps that can monitor incoming charge though not as effective as the hardware for monitoring charge but it'll give you a fair idea if you check it out.
I think you should reach out to Asus for solutions if possible, a replacement unit.
All the best.

Are you Ok Now?
I am facing this problem.This is rom problem?
FYI you can check the arrows in the battery icon when charging. 2 arrows means full speed - I guess -
Don't know if that's helps, I heard once that if charging percentage jumps in blink of an eye, then it's probably its need to collaborate battery mah with phone and it's done by dischargng your device by using it tell the phone goes to 0 and shut down it selfs , then charge it to 100% fully ..
Another app to see how fast your device being charged it's : accubattery , this is so far best option , but this app for analysis not for always use because it's consume battery like all other app
