Hi. Is there a way to sync your device with the desktop pc without charging your device everytime you connect through USB? If it gets charging everytime I sync the battery will go bust in no time!
Thanks
depro
no only ni-cam batts suffers when you charge them without them being empty already
li-ion like all pda's and phones use today benefit from being charged often
Hi,
is there any way you can disable charging via USB. This is a feature available on WinMO devices and should help extend battery life. If you often plug/unplug the USB from the device, the battery will constantly being charged for a short while. Even if LiIon battery that's not good to do all the time.
Anyone found any mod?
Pete
can anyone help???
Has anyone found a mod to this?

I would also be interested into this. If there isn't an application for this yet then you could also buy a SD card reader USB
and connect it on your computer to transfer files, although it could be a pain.
I am also expecting a solution for this for my Xperia P.
There isnt a solution, it doesnt have to be a solution since a common misconsumption is that Li-On batteries have memory, they dont...
You do know li-ion has limited number of charges. Those 5-10 minute charges everytime the phone is connected counts towards that.
Yes, i believe that in CWM delete battery stats gets rid of that...
Hi,
I read about peoples Tab wouldn't charge and they can use a script to enable USB charging.
I need to disable USB charging as I want my battery fully and continuely charged for battery lifes sake without getting small charges whenever connected via USB to the PC.
How can I achieve this?
Please use the Q&A Forum for questions Thanks
Moving to Q&A
disable USB charging?!? new lithium ion batteries aren't as sensitive to partial charges as previous generation nickel cadmium batteries: Link It may be better to keep your battery at 100% with charging to prevent the number of discharges of your battery.
back to your question:
you do not have to do anything if you do not have the tab rooted and script installed.
if you are rooted and have the script installed, you will have to go to script manager, find the script, uncheck "Boot", and restart.
Hope this helps.

You need to update your information on battery technology. But if you really want to disable USB charging (assuming you're on a ROM that has enabled it) just go to the second post in the Galaxy Task thread in the dev section.
just so you know. that even if you disable it, it will still be charging. just not as fast bro. even with that little X picture on the battery it still is receiving a charge no matter what you think. Its not a bad thing to charge here and there anyways. its doesnt harm you battery at all. its good for it.
I have read multiple posts talking about battery life problems suffered after the ICS update. However, my question is regarding the time it takes to charge the phone using a usb. I know the fact that usb charging is slower than wall charging. But what i am comparing is usb charging before and after the ICS update. My phone is not rooted and has the OTA update from motorola. Also, it is a RAZR and not RAZR MAX.
The question is, has anybody noticed that usb charging is slower after the ICS update? I used to plug in my phone with usually 50-60% battery life in the mornings and it always used to be fully charged before lunch. Now, the whole day goes by and it barely reaches 100%.
The phone, the usb cable and the computer are all the same. Only the software has changed.
My initial guess is that the 'charge only' option that used to be available before did a better job of sending more current than the options available under ICS.
Does anybody know of a way to fix it ? With or without root?
Thanks,

I ran into your post after googling the same issue for my cousin; also started after ICS upgrade, but her phone is Xperia S, and its not only affecting USB charging, but even the wall charger is much slower now, more than 4hrs plugged for 30% charge only, when it used to take less than 2hrs for full charge before.
I've always had trouble charging my phone on a computer via USB. It goes way faster when on a wall charger.

there can be more than one issue for this.
1) could be the battery stat. but to wipe this you need to root your phone. Maybe just charge and discharge it a few times completely (till it shut's down automatically)
2) other charging source? are you using another USB-Port to charge it? it could happen, cause your phone has to 'tell' the USB port it's some kind of high power device to get 500mA and not like mouse and keyboard only 100mA. does the PC recognize the phone? are your usb ports unlocked (yeah, i know... even locked ports supports power, but maybe not enough...)?
3) do you charge it while running? or in shut down state? ICS seems to drains some more battery life while running then GB...
PS: charge only option is no more usable but ask an IT-provider to get a 'power-only' usb cable. i've got some and it only provides current, it's like normally charging
PPS: best rooting solution > get Arctic ICS (GSM/CDMA) or Epsilon (GSM) ROM, usb charging in less then 2h! for better result use the 'power-only' usb cable mentioned above
Another essencial tip is always charge through back usb, never in front and disable wifi, gps, data, bluetooth it will make phone charge more and faster.

mentioned that too, is there some explainable reason for the front / back end differences?

I agree. Wall charging is always way faster than usb charging but my wall charger usually stays at home. That is why, i use the usb charging option at work.

My phone has discharged completely twice since the ICS update. I am not sure but that might have reset the battery stat. Is there a way to check it on a non rooted device?

The phone is plugged in to a USB port on the computer and is recognized as a Motorola RAZR. I also have the Motorola Device Manager installed which i believe installs all the necessary drivers.
Also, I have tried multiple ports (front and back) and i have seen similar results in terms of the time it takes to fully charge the phone.

I do charge it while running and wifi on. Data, Bluetooth, GPS are off. I always used to charge it this way. Its sad that the same state in ICS drains more battery than GB.

I didn't know of a charge only usb cable. I'll try to get my hands on one and let you know the results.

I have so far avoided the root option since i am a little scared of bricking the phone / what if i am not able to restore it back to stock / unable to update phone to future software versions etc.
How does rooting the phone increases the speed of usb charging? Is the software that is being flashed on the device modified in certain ways that is not done as part of the .211 OTA update?
I have also read about the .215 leak. Do you know if the usb charging speeds are different between the two .211 and .215 versions?

For me i don't have any experiences with CDMA phones but what i read was a significant better signal state and battery life in .215 ...
Looks like they improved the system processes / memory usage to get less battery drain. This should be good for charging, because while charging it would drain less battery life / it's charged faster.

Rooting itself will not bring you any advantage in battery drain / charging times. But a rooted phone is open for kernel tweaks and custom ROMs.
Tweaks are used to improve the CPU to get more power or better battery life.
ROMs can be de-odexed / de-bloated to get rid of every senseless app or system process that drains battery while running in the background.
And this improves your battery life AND charge times
PS: There should be some stock ROM from EternityProject as emergency unbrick for CDMA too. Just use the search function, you should be able to go back to stock from every custom ROM.
I want to disable adaptive fast charge on g925f, I don't have other power charge, I want to continue to use the original charge but without fast charge, is possible?
I have root, twrp and busybox, any solution?
Why, I used my old lead and plug from my S5 and then realised needed to use the S6 supplied ones, what a difference and convenience.
Sent from my SM-G925F using XDA Free mobile app
I think it's embedded into the chip itself, why don't you buy a original charger but without fast charging, save you a lot of trouble instead of disabled fast charging capabilities
can not disable it so just don't use it use a non Samsung box when charging and itll just charge like normal,there is no way to disable it root or no root cant do it its built in to the phone it self not even a program
