in the power setting, under information
my D2 couldnt show any information
last full charge: not applicable
why is that??
anyone have same problem?
It's kind of a dumb question, But it does only show information when your device is fully charged (green light) It does take a while

It's not a dumb question.
There are quite a number of TD2s out there that cannot attain full charge. The battery status remains at 99% regardless of how long you charge it. Hence, no green light and the last full charge field remains NA.
Mine charged well...
received it with a half full battery... I used it till it had no power left,
Then charged it over night and tadaa! green light in the morning
So now I'm letting it drain again, and then fully charge, so the battery calibrates
Not that I know sure, But my father's phone cannot charge to 100% either, because he didn't drain the battery when he bought it :s (Well that's what they say in the store)
I did drain the battery three times and loaded full.
The point is that the display of battery charging has a bug, if the device is on.
Charging works perfectly, when device is off. But the information screen won't be updated.
Have a look at this thread:
-> Battery Charge issue - bug? Reproduceable?
Pardon me, but why do you need your last charge information anyway? As long as the battery lasts until your next charge, it shouldn't bother right?

Will you sleep easy if your phone doesn't recognize when it has obtained a full charge and stop charging the battery?
I wonder if the built-in protection circuitry on the Li-ion battery will stop accepting a charge when it's full. Is the phone capable of overcharging the battery and become a fire hazard?
I think its common knowledge that the HTC One has a slow charging speed compared to other smartphones.
Thus, since i use my phone all day..on the move, leaving it to charge at a stationary spot is rather annoying, so therefore the only workaround is to charge it overnight and use it during the day. But the problem with this is that it'll be done charging far before the night is over, and stay plugged in, therefore my question is, (or rather two questions)
Does the phone automatically stop charging once it hits 100%? Or does it continue to keep the phone at 100%, reducing the battery life of the phone?
HTC should have included a faster charger. My One takes a few hours to fully charge and doesn't even really charge when I'm using it while charging.
As for your question, I don't have a actual answer but I imagine it maintains the 100% charge by constantly charging it.

A faster charger wouldn't make a difference as the amount of charge the phone can accept is determined by the phone itself. The phone requests X amount of power, and the charger provides it, as long as it is capable of outputting that X amount. A 2amp charger wouldn't charge the phone faster.
And yes the phone has an intelligent charging chip. It stops charging at 100%, and drip feeds the phone when it detects the battery level going down. On the HTC One X, they did it in a weird way.
The charger goes up to 100%, then lets the phone go down till 95% before starting to charge again. This confused a lot of people as they would unplug their phone at 100%, then 1 phone call/text message later it drops to 95%, showing the real battery level

This is exactly what i was looking for, thanks. So it does stop charging at 100%, allowing me to charge it overnight beyond the length of its charge cycle without reducing the battery life?
I understand that dropping down a bit and charging again is better than constantly keeping the battery at 100%, but isnt it technically...still bad for the battery in the long run?
Is it normal behavior that supercharge "slows down" as it gets closer to full charge?
I am asking because i have noticed that my 1 month old P20 Pro charges slower even though it displays "supercharging" on the display? Maybe i am imagining things, because the battery was at 89% when i plugged it in.
I have used Ampere to monitor the charging current ant it stayed around 750mA during most of the charge and dropped to 450mA at the end.

As far as I know, the low battery power of mobile phones is usually due to the fast charging speed. When the charging rate reaches more than 80%, the battery power is close to the full. In order to ensure the safety of use and extend the battery life, when the battery is rapidly charged, the charging current output by the charger will gradually decrease and the charging speed will slow down until it is fully charged. This feeling is normal for you. How long does it take you to charge from 0% to 100%?
Yes - This is generally a safety measure for the battery.
How long does it take from 0% to 50% and as far as I am aware it slows down from 60%
Thanks for your replies bobo and mulkman.
It is reassuring that my device is ok and (hopefully) I am only imagining things
I haven't had the chance to charge from <50% to 100% but I will leave the phone to go below 50% over the next few days and charge it up to 100% and post the result.
Finally my phone discharged enough so i could do some charging.
Started at 44%
Total charge time 66 minutes to 100%.
Supercharge indicated 100% of time.
Meassured approx. every 10 mins (6 time points)

Hi!
Check whether the phone and the power adapter are connected properly. And you should use box accessories (original) charger.

Connection is as good as it gets and I use the charger and cable supplied in the box with phone.
Is ~40% - 100% in ~1 hour normal charge speed? (Phone is on, screen off)

Hi! Was your mobile data on while charging? Because it takes more time when mobile data is on or mobile is heated up.

Everything was on, but the phone was on WiFi. Temperature of the battery did increase to 32 degrees centigrade (checked in Ampere). The phone is in a original Huawei smart case, which may increase the temperature.
It's probably about right. It slows down at the top. Attaching a couple of charging sessions for comparison. You can see that the percentage per minute decreases when the battery reaches the higher levels of charge. At the rate of the first picture/occasion it would charge the battery in half an hour. But that's not the case since it slows down a lot.

Good to hear.
Is your phone in one of those TPU case and if so remove it before charging your device.
The charging speed is dependent on the current battery temp so it may throttle if your device gets too hot

Yes most definitely.
Have you ever noticed that the phone gets warm during the first 0-70% of its charging cycle.
Towards the end the phone enters trickle charge mode to protect the battery

I haven't noticed before. I usually have my phone on the table while charging and i dont pick it up. But when monitoring with Ampere I noticed that the temperature went up.
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
My old htc m8 charger got damaged after just a few times of using! Seems like the phone drained it dry
Hi there,
to be honest, I have posted that question already in the P30 forum. But as both devices are quite similar and the Pro has a wider reach I decided to repeat it here. I hope you don't mind...
With the new EMUI10.1 also the "Smart Charge" feature arrived. Well, here at my P30 as a switch at least. I am really not sure, if this is working at all. I have it activated since idk 5 weeks or so and am using the original cable and charger. The charging curve, as can be seen in the battery settings, is not displaying any slower or even paused charging speed, the curve goes straight up until 100% ~1h after plugging in. Also there is nothing indicating an activated smart charging right when I plug in the charger.
What is your experience here, can you guys see any difference, have you seen any proof this is working?
Many thanks.
Yes, I've noticed it on both of my Huawei phones. It basically slows down or even stops charging so it doesnt max out, in order to preserve battery life. So you can leave it on the charger forever but it'll never hit 100%. My P30 pro sits on the charger almost daily and sits around 80-90%.
Maybe it has an algorithm that knows when you dont use it and charges to max then? My phone is on a wireless charger about 95% of the time throughout the day and night because it isnt used often. Sometimes it'll popup telling me that its using the smart charge feature and if I want to disable it blah blah.

Thank you for your feedback! So it is not working as it should. I got it should "understand" your habits and charge it accordingly, never going over 80%.
It's a pity, I found it really useful, but if it works like this it is useless.

According to the official, smartphones powered by lithium batteries ages differently, which results vary in terms of charging or simply called slow charging as well as short battery life.
For example, if a user leaves the charging overnight or for a long time. The charger keeps supplying the power to the battery, a state called overcharging. Repeating this process causes battery aging.
But with accurate management, the battery aging can be slow down and extend the battery life.
This is where Smart Charging Mode comes in place and uses the phone’s built-in AI capabilities to learn usage patterns. To slow down the battery to charge 100% when required.
For example, if the smart charging mode is enabled and the battery reaches 80%. The charging automatically slowdowns (charging rate) before it reaches 100%. This whole process prevents the phone to keep charging at 100 percent without harming the batter
P20pro here, same problem. Night or day, it seems to charge at the same rate, not waiting at 80%, no sign of that toggle doing anything.

None... Charges as usual over night. Goes to 100% in about 1 hour and stays there
So basically it charges up to 80% in regular mode, after it starts to charge or very slowly or just before u wake up to 100%.. Yes, is learning at what time usually u touch for the first time the phone..
Or at least, this is what should do

Exactly, "should do". Instead the phone is charging quickly and straight to 100% without any slowdown.
