Anyone has any idea why do we need to turn on "disable usb charging" ?
Settings -> Power -> Advanced
[ x ] When device is turned on, do not charge the battery when connected to the PC
In what situation?
One thing that I can think of ... is to preserve the battery to have a good condition by only charging if you have "enough time". That means, to charge until 100% and beyond.
Any more valid / good reason?
Thanks.

In my case, i thin is better to make three or four completes cycles of charge/discharge, so for the moment i use this option to prevent charging while i connect to PC to install or trasfer something....after complete discharge, i charge full...

Hi,
It's probably to preserve Laptop/Notebook battery when on the go...

Yes, this is another one.... i don't have a laptop so i don't think in it
I reckon its so you can plug it into a unpowered USB hub which is near its limit of how much power it can supply...

charging
i think it might have something to do with the amps/volts, i'm not a scientist as you could already tell, but i do know that you shouldn't use a motorola charger to charge an htc product. i used a razr charger to charge my dash once and it killed the battery pretty well. so i figure you shouldnt use a non-approved charger to charge your device, be it via laptop or any other charger that didnt come in the box
My bet is that this is about battery life. I think that these batteries do best (live longest) if they go through complete charge-discharge cycles at least every 30 days.
I plug my TyTn into my computer when I am in the office and, unlike ACtiveSync, the charge always works!
I vote for the portable use theory as well, so you don't drain the battery on a laptop or unpowered hub that can't supply the additional current.

I'm with you on this one. Current gen batteries don't need to be cycled so much for optimal performance. However, charging your phone via USB will drain your PC's battery more quickly if you are on the go.
The Kaiser draws a lot of current. Even when charging by USB I have seen the battery level dropping.
I have seen quite frequently USB ports being disabled due to too high current draw, making the connection unstable. If this was a problem this option would prevent it.
Surur
quite a few posts here about li-ion batteries and how best to look after them:
http://www.modaco.com/Warning-Battery-Chargin-t233233.html
That's good stuff especially the Wiki on them. I use a lot of lithiums at work and play. Bottom line, don't run them flat, ever, that's the only thing that will ruin them quickly. Most devices have protection circuitry to prevent this by shutting down. When you get to this point the battery should be charged ASAP because the small amount of drainage in the device will take the battery past the critical low point if left in this very low state for any length of time (say more than a few days).
Cycling really doesn't do much for lithiums, their total capacity decreases from date of manufacture slowly over time, weather you use them alot or not. This is unlike other batteries.
Best storage state for lithiums is 50%, not full. But in a phone, best rule is to just top them up whenever possible, plus you never know when you are going to get that marathon phone call
As a few others have alluded to, this is used when you're tethering on the go. WM5 / 8525 doesn't have this switch, so when tethering via USB on the 8525, it will literally suck the life out of my laptop battery.
Glad to hear that this switch was added in WM6 / Kaiser.
The best battery information I found is here: http://www.batteryuniversity.com/parttwo-34.htm
Summary (for li-ion batteries, as in Kaiser):
1. Avoid full discharge; partial discharge/charge cycle is better. However, a full charge/discharge cycle once every 30 times is useful to keep battery gauge calibrated correctly (doesn't really help longevity, but prevents erroneous gauge from forcing early retirement of the battery).
2. Avoid prolonged storage at full charge and/or high heat (optimal charge is ~40%).
3. Avoid high rates of charge or discharge. Presumably the charge rate is already set at an acceptable rate by the manufacturer; as for discharge, it probably can't be helped if you need to run some ultra-high load applications on the phone. One thing this confirms: it is good to charge the battery using the USB; the possibly lower voltage available during the USB charge is helping, not hurting, the battery. So definitely, the "do not charge when plugged in" option is only to save your laptop battery, not to help the phone battery.
As said already in this thread, its so you can connect to a non-powered usb hub or a laptop usb port that can't supply enough.
WM devices normally detect supplied power and go into charge mode before they are polled by the PC/Laptop via Activesync for data transfer. If the charge system pulls the port down then data transfer is disrupted.
When tethered to a laptop and the laptop is running on battery, you may want to disable charging to conserve the laptop's battery.
This is the answer I got from batteries4less where I bought a replacement battery for my 8525.
You should generally charge your battery every night. It is not good to do
it continually during the day. It will wear it down faster. Thank you

By the way.....shameless plug: I ordered a battery late on thursday afternoon and received my replacement battery on saturday and installed it in the phone. On monday I bought the Tilt 8925 and then emailed that I bought a new phone and asked them if I could exchange it for a Tilt 8925 battery and the next email I received from them about an hour or so later said the new battery was on the way and to send the 8525 battery back in that package.
These guys will get my battery business from now on.
Years ago i had a t-mobile dash also known as an htc excalibur, and i would use it to tether to my computer for 6 to 8 hours a day as a high speed modem and low and behold, it burnt out the battery. I bought a new battery and switched to Kaiser OS that had an option to disable usb charging and never had a problem after that... Now if you only connect to a computer to transfer a few files back and forth every onle in a while then there probably wont be a problem because that is not going to drain your battery very fast so it will only charge every once in a while and that is ok. But when you tether to a computer to use your phone as a high speed modem it takes ALOT of battery power. I saw a post in a different thread here on xda that said that when your battery reaches 100% that it stops charging. Yes that is correct. But even though the battery will stop charging at 100%. As soon as it drops 5 or 10 % is starts charging again and when you tether your phone as a modem it will drop 5 or 10% within minutes so your phone will basically be charging nonstop which is defiantly not good for a battery and that my friends is what the disable usb charging is for.
Just as an added statement for those of you that disagree with what i have said. Try it yourself and see what happens. Tether your phone to your computer as a modem and surf the net, and play games, and download stuff for 6 or more hours a day. I bet in just a few weeks or months you will be replacing your battery too.
Reason to turn off phone charging when connected to PC
I installed "Syncois iOS & Android Manager FREE" to back up my Android phone data to my PC. The program would not work if my phone was charging when connected to my PC, it told me. So, I had to turn that charging option off. Outside of that, I will always have my phone charge when connected to my PC. Hope this helps!
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.

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%. But the problem is that my stupid Windows doesn't report the life of the battery accurately ::- (. I got a Mugen 3000 Mah batt...

Hi folks,
Been searching for a hack or tool to disable usb charging while connecting device to laptop usb port to prolong battery life. But to my disappointment, there's none at the moment
Aren't there any solution for this at all from the developers?
So far, the only tool that I've googled is USB Charge Commander but that doesn't work on Galaxy S
It's designed for ZTE Blade/Orange San Francisco handset only.
Appreciate for any tips given. Thanks!
Sassy,
there is no need for such a tool. Since you are using a Lithium-ion battery this would NOT prolong your battery life. This type of battery has no such thing as a memory effect. The battery will take no damage if you charge it every time. You don´t have to wait till it is fully empty. Actually, if you discharge your battery completely every time, it may cause shorter battery life in the end...
Have Fun
Chris
How about this for a reason:
I don't want the phone to charge off of my laptop which itself is running off of a battery, but I do need a USB connection for application debugging. My laptop's battery does not last nearly as long as my phone, so I would prefer that the phone does not charge via USB when my laptop is running on batteries.
No solution?
USB charging shortens battery life
Indeed, I've been looking for such a solution of USB connection without charging for my Galaxy S. I also came across a suggestion of clipping the power +5V wire of the USB cable which I believe would not work as that would disable the detection of USB connection.
Back to the battery life of lithium battery, we know that partial discharge is fine as there is no memory effect. However, every discharging cycle matters and counts if we believe the info from the Battery University page, Table 2 (batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries). According to the test and assumptions, if we charge the battery at 10% of Depth of Discharging (or approx. 90% of capacity), we have 4700 cycles before the battery is worn out. Yeah, 4700 seems a big number. It is not that big if we connect our phone via USB to a PC very often.
We don't know the exact no. of discharge/charge cycles a li-ion battery on our mobile phone can tolerates before its end of life. If you believe EVERY CYCLE COUNTS, you'd better find a solution.

Typical laptop batteries are around the 4.4Ah mark, the phone draws 95mA from the USB port while charging. This means you could charge your phone continuously for 46 hours off a typical laptop. You won't notice the difference in practical usage at all. This is about the same amount of power as your laptop CPU doing actual work for a few minutes. There are many other factors that have a far greater impact on your laptop battery than charging a phone.

If you look at the table in detail you'll find that 4700 cycles at 10% recharge is roughly 10 times the 500 cycles at 100% recharge. It's an almost linear relationship and there's nothing to be gained by letting your phone discharge further rather than putting it back on charge when it drops to 10%. The cycles aren't a counter after which suddenly everything stops.
Also they are hammering their battery pretty hard. A 1C charge is roughly 4 times higher than what the SGS battery experiences. The faster the charge the lower the life, so expect your phone to last longer than 4700 cycles.
On top of everything with replacement batteries costing a whole $5 it's not worth losing sleep over.
Yeah, you're right. If a replacement battery costs that little, even my quoted analysis really matters, it does not worth 'counting' at all! Just use the way you want and make sure you got one replacement before it's out of market.

I 've lost my original charge.so I have to use an Ipod charger to instead it.
But the phone seems very hot every time charging. What shoud I do now?
In additional, the battery drained so much. It took 4 minutes to lose 1% battery.I 'be bought the phone for 6 months,so why does it drain battery so bad?
Please help me and forgive for my bad in English.
2 options:
1) Your battery is fried.
2) Something is running on your phone that causes it to drain battery (forgot GPS app running in the background or something?), which is also the reason for heating up.
How can I know that my battery was fried? Example like how many mAh are there in my Batt?
I was looking for BatteryDetective (like in my friend 's iPhone 3GS) but it is no avalible for my device.
Also,how to check what was running in background? GPS is alway turns off when charging,certainly
I turned off the phone and charged.and it was still hot,but not much as when the phone turn on
In general, using a different charger won't damage your phone. Apple chargers are often capable of supplying more current than other chargers (for example, 2100mA rather than 1000mA), but the phone will only draw as much current as it needs. As long as the charger is supplying proper, in-spec voltage, you shouldn't see any difference. Your phone is probably getting hotter because it can draw more power from the iPod charger than your old charger, and can now charge the battery faster. I wouldn't worry about it unless the heat is causing problems. Cheap, off-brand chargers sometimes don't supply proper 5V, so don't buy crappy chargers.
Your battery discharge rate is a separate problem. You can check what's been using battery power in Settings|About Phone|Battery use. In my world, Display, Wi-Fi, Cell Standby, and Phone Idle are usually the top items. Checking the wear level of a regulated LiOn battery is kind of annoying; they're cheap enough I just replace them every year or so (500 cycles is a pretty good lifetime).
Thank you very much !
Are there any app like BatteryDetective for android? I 'd like to know how many mAh of my battery
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?

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.

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?

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
