Is charging our Kaisers from the PC ok? How much power does the USB provide to the Kaiser? Same as the standard adapter? I am asking this because I found no answer on the forum and I would prefer to load it directly from the PC every time rather than keep using the standard charger and putting it in the power outlet.
my advice for you to stop this option
because normaly we keep the phone connected to the pc for a long time and it makes the phone in charging mode all the time and iam sure that will make the battery dies fast
stop this option by disabling it from the battery options you can see it by clicking on the battery icon on the start bar
greetings
My phone has been plugged in to the USB at work all day, 5 days a week, for 5 months now. I can still get about 2 days out of the battery when I need to - for instance, after unplugging it each Friday at 5 I usually won't have to charge it until the same time on Sunday, the only time it generally does get plugged into the wall charger. I'm pretty sure my battery performance is still on a par with most people's - ie, not amazing, but quite livable with. It's certainly not showing any signs of harm from overcharging.

Same here.. no problems. I don't even know where my charger is.
I charge mine from the PC all day too, and it stops charging when its at 100%. The bottom line is this: a USB port delivers a minimum of 500ma at 5v, the wall charger is probably very close if not more than that. The charging circuit in the phone does all the work of converting the 5dc into a charging voltage/current required by the battery, usually ramping up and down. Theres no difference other than maximum current between a USB port and ANY 5vdc adapter.
Wall wart gives 5V/1A. USB at 5V/500mA will not harm your battery. If you're using the standard battery, USB charging is appropriate to keep it topped up.

Isn't the constant charging of the batter bad for it?
I mean you charge it use it for a while then hook it up again and so on, isnt it better for the battery if you wait until it says that you have to recharge it?
According to my BatteryStatus, my wall charger gives me around +500-600mA (depending on programs running) and USB 2.0 charging from the front port on my computer gives about +100-300mA (depending on what's plugged into the computer and program usage).

That was a nicad battery issue lithium batteries do not have that issue.
-McMex
i think the point here is not if you charge it by usb or charger
for many people as they said it goes as well ok but it's an old advice used to be known that it's not good for your battery health to be on the charger all the time
also the same fact that it's always better to let the battery goes empty before you recharge it again some people have the sickness of recharging batteries when it's just gets 5 percent less , then they immaditaly start to recharge it again and this is a big mistake because in the long period the first levels of the battery start to die because they have never been used

Actually, its quite the opposite of what you say. If you let Lithium batteries discharge all the way, they will loose their capacity faster.
The following link will back up my claim:
http://batteryuniversity.com/parttwo-34.htm
Relevant quote: "Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns."
usb v wall charger
My kaiser
wall charger charges battery from flat (1%) in 1 hour
USB on PC takes 4 hours to go from 15 to 80%, only over night did it get to 100%.
I use wall charger everyday now.

i use the pc option especially when i am traveling and only have my portable. When using my portable, i plug my phone in to get a charge... i like this option as it saves me from having to lug around another adaptor as well as being able to charge my phone just off the batteries of my portable at any time,,,, good option
posted twice --- as usual being a post hog
It's fine. It just takes longer to charge, especially if you're transferring a lot of data.
With the lithium ion chemistry, it is very detrimental to the battery if you let it run down to empty all the time. The batteries do not like this at all and will exhaust much quicker this way. If you were to store the batteries, you should store them at 40% in a cool place as that would only lose 2% of life per year I believe. At 100% storage, you can lost 20% a year of life. A little reading at that battery university website goes a long way

So what happens when your battery that you leave stored at 100% loses 20% a year and a few years later it hits 40%?

haam1978: You are surely right for NiMh. But I don't know about Li-Ion. Time will tell. For now, I prefer to do it your way: discharge almost completely, BUT NOT TO 0%. Mostly to 5 - 10%.

100% correct.
On a side note, my kaiser will get fully charged way faster when connected to the wall as opposed to USB. (always connected to a desktop with a real big UPS).
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

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.

Sent from my [device_name] using XDA-Developers Legacy app
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

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.

I'm currently on Android 11, june patch. Just got the phone this week and noticed something very frustrating. I can generally "fast charging" as i only have a 15w charger for now. But sometimes if I unplug it and plug it back in, it just says "cable charging" i have other chargers and it's the same.. sometimes it says fast charging, but i downloaded Ampere and can see it only at 300mah and only goes up very slowly.. 1% every 4mins..
Anyone else with these issues?
Just try using the official charger and cable because everything else would be way dangerous. The same thing you have mentioned is happening to me as well. Try changing the way cable is plugged in. Turn it upside down.
Im using the 25w charger, Samsung original and neve chared with the stock 15w charger. It shows super fast charging, no problems here.

yeah def charge with Samsung OEM charger
Meh, fast charging only will engage with 25 watt brick that is compatible.
$15 for a Samsung 25wbrick/cable at Walmart online, what's not to like?
I have 2 sets, the first one is over 1.5 years old and still runs A-OK.
jeeeesze...
Yeah i plan to get the 25w charger, just waiting on delivery. I'm just trying to reduce buying so many as i have so many spares from old phone that charge in just over an hour SOMETIMES And over 3 hour at other times! Frustration is even if i unplug and plug it back it, it never seems to go to fast charging unless i let it discharge a little. Winter here and it's cold so temperature of battery has been fine.

Temperature matters. Charging is an electrochemical reaction. Too low a temperature and fast charging will not engage. Charging below 72-82F can cause Li plating to form which will permanently degrade the cell.
Never attempt to charge a Li at 40F or less!
Best battery start temperature is 85-95F
Li's fast charge best in the 90's.
Below 60F fast charging may not engage and it will slow charge for the remaining cycle.
Fast charging will disengage around 80% and at 90% will slow even more. This is to protect the battery.
If the battery temp get above about 101F fast charging will disengage. At around 104F it will stop charging all together.
Cool battery as it approaches 99F with a fan and/or damp microfiber cloth.
At ambient temperatures above 90F cooling will likely be needed for fast charging.

I don't really work with Fareinheit, but after looking, battery is reporting it as around 29degrees when charging. It does seem to be more consistent the last 2 days, i wonder if it's because the OS was still trying to learn my usage. It still happens, i just need to unplug and plug it back in when it says slow/cable charging. But haven't tested it too much, so still unsure.
I am still waiting on charger, i'll keep this forum updated in case anyone else is interested.

Meh you do the conversion. For actual living the Celsius system is awkward at best.

Lol, i did. Temperature was fine.
I received my charger after i typed up message. I used it with super fast charging getting 3000mA from ampere app. Worked great unplugging and plugging it back in.
Tested using it on my s10 charger, and it showed up as fast charging, unplug, plugged it back in, cable charging only.
Went back to the 25w charger. It says super fast charging but hovers aroud 1000mA.
Can't get it to use high speed. Temperature at 28.5 degrees.
The only way for me, let it drain 10% and put it in the charger again to get 3000mA charging speed. The message that says "super fast charging" means nothing to be honest.

In what battery % range are you charging? It should draw closer to 4000-5000 ma at its peak fast charge rate with a 25w brick.
About 2%@minute when fast charging at peak rate.
Erratic fast charging can indicate a battery failure.
Any swelling is a failure. Replace immediately it this happens.
Other signs are deminished battery capacity.
Try clearing system cache.
Toggle the fast charging switch on/off 3 times.
Discharge until phone shuts down then charge to 100%. Some say to do this 3 times but one cycle worked for me to recalibrate the battery gauge.
Fast charging is a little b*tch when it goes south but always suspect a battery failure if this happens. A swollen battery can damage and destroy the phone.
Battery failures can happen at any time but are more likely to happen with degraded Li's.

Thanks for the response, with the testing i've done, it's been 70% to 100% only.
i've been needing my phone for work, so i haven't had a chance to discharge it. Will try it this weekend.
Do you charge it back to 100% after a complete discharge with the phone Off or On?

At 70-100% you'll see much slower charging.
Li's prefer frequent midrange power cycling. It can extend their life by hundreds of full charge cycles. Example 40-70%
I rarely charge to 90-100% usually to 65-82%
I almost discharge below 30%, 40% or so being typical. Below 20% there's not a lot of usable energy. It also stresses the battery more when charging from a deep discharge state.
If you insist on charging to 100% at night at least slow charge it to reduce battery strain.

i drained it to 0% until it turned off.
After turning back on, i plugged in the 25w charger and it started charging at 4000mA and max 4750 for only a few seconds for the first 10% and after that, it went down and stayed around 3000-3500mA. happy for that for now. So thanks for your input.
Basically, to get fast charging/super fast charging, don't unplug and plug in a few times unless you have to as it will revert to cable charging, and then you'll need to let it drain a little bit (i found, around 10mins ) before plugging it in again to get the fast speeds.

Having the display on skews the charge curve, don't. It will charge slowly or not all if the display is on.
It you turn the display with it the battery page already open you have one or two seconds to see the display off mAh charging rate.
You can easily tell it's fast charging by watching how fast the battery percentage changes with the screen off.
1%@minute or less slow charging
2%@minute fast charging is active
Fast charging will ramp down depending on inputs like temperature and charge percentage the power controller recieves.
If it starts or goes under/over temperature fast charging will disengage for that charge cycle.
It also will ramp up/down sometimes throughout the below 80% range. This is normal.
Being in the optimum battery temperature range at the start and throughout the charge cycle is important but don't go too nuts. Higher is better than lower. Once the battery is below 70°F it will not fast charge as well (or at all) and/or can detrimental to the battery ie Li plating. There maybe other parameters the controller uses as well... not sure.
Oddly the Samsung 25w bricks are very tolerant of low input voltage. They will charge with as little as 60 VAC!
Like a few have said, fast charging like that will degrade your battery faster due to high temps, but the way you use it has a big impact on that. If you fast charge at those speeds to 100% take it off and use it constant until dead, and put it back on the charger then you will deff degrade it faster. Lithium cells need to rest between charge and discharge to let the the temperature settle. If not it's taking a hugh work load wearing down the internal resistance which drops the cells Mah rating.
Yeah, Im guilty of this too many times lol
Manufacturers know this as well but they know people want fast charging and largest battery capacity possible, they could at least make an option to lower the voltage down from 4.20v and a charger allowing us to switch between a few milliamp ratings..

You're correct it's best to allow some rest after charging and to not fast charge.
In practice this goes out the window
I do try to keep the voltage down as well as the temperature below 100F. Ambient temperatures here are frequently in the 90's
If I get a year out of this new battery I'm good with that.
However once it's down to 80% of its original capacity it gets replaced to avoid a failure. That's what happened to the original battery and I was lucky it didn't damage the display.
Below is my typical usage and the 10+'s fast charging patterns. The last charge ended with a near ideal battery charging temp of 94F. It fast charged nearly the whole time.

Jeez, had that app for a long time until about a year ago... I use AccA on a Rooted Pixel but id say I started using it a bit late.. You know none of this would be an issue if they still used replaceable damn batteries!! Lol My old Bar & Flip phones before color screens lasted days to over a week, and still had spare battery near by... My Startac even had a Solar panel battery

Yeah I have a flip top and S4, takes about 30 seconds to change the batteries. Most of the newer Samsung's aren't that bad to change out the battery once you know a few tricks. Some phones with multiple batteries are bloody nightmares though.
Solar panel? That's pretty funny
One way to limit phone usage.
