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

I noticed that my sync n charge retractable cable has stopped charging my BA because while it is connected, the power keeps dropping and on one occasion completely drained and switched while connected overnight. It can still sync though, and the charging light is on. While connected the power setting screen displays charging. What could be wrong? Do I need to get another sync/charge cable? It can still charge with a wall charger, though.
are there any programs running in your BA?
are the backlight set to the minimum?
how about your battery?
i've had an experience with a "kinda same" event like this.
with my old battery... im playing music while plugged in.
and it seems my battery is discharging more power while charging less. it couldnt compensate with the discharge so its climbing down slowly rather than charging up.
but.
when i replaced a new battery it didnt happen again...
i know it will occur again as my battery wears out.
where to buy?
yo silvah! can u buy usb sync-n-charge sa pinas?
just pmed you!
wow!
I know this is off topic but i gotta say it. Airfagev, pinoy community rules!! who started this site anyway?
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...
Ever since I updated to 2.1 it seems that when my battery gets around 15% and I try to charge it via USB, nothing happens and the battery just drains even faster.
The only way to make it charge, is to switch of the device entirely and charge it while it's off.
Im not sure if anyone else has this problem?
I'm not entirely sure but I think that's a bug that has always existed on the X10 series, it has happened too me too in Donut
Yeah, I've seen this happen too. Turning the phone off and on again usually seems to make it charge properly
When charging via a laptop i've seen the charge go down when i've had the wireless on and been playing movies etc...
Possibly because the amount of charge than can be delivered via a usb (not connected to a plug) is very small
Same here. It happened to me in Donut and also now in Eclair. But in my home PC and Laptop it charges normaly but slow. But in my office PC it gets discharged. Is there anything with the PC too?
i did a bit of a quick test myself on this yesterday.
i plugged my phone into the usb and set it to the charge phone option, then closed all apps, turned off data connection and gps and left it with the screen off for 30 mins. after this time my batter had dropped by 2%. i unplugged the phone from the laptop and left it, again with the screen, data and 3g off and in 30 mins the charge dropped by just 1%.
there must be a bug with this in the system somewhere as this is soo annoying for me. i will try and turn the phone off and charge it later [when the battery dies after less than 8 hours with normal use] and see if that works.
got to say that i am very disappointed by this :-(
right for an update. i have just connected my phone to the wall charger, left the data connection and 3g on and left it charging for 30 mins. the result was an increase in charge of 17%!!!!!! thats more like it

The USB spec provides for 500mA of current at a USB port but it could drop to the lowest spec'd voltage while doing so, which could reduce the charging rate even more. If the USB port is actually a secondary port from an internal, self-powered hub, it might even limit the current to 100mA. It all depends, many USB implementations aren't known for following the spec's terribly well.
Some newer USB ports will comply with the latest spec's that allow higher charging currents (to 900 or even 1500mA).
So i just played with Custom ROMs to find the best for me...
But from one point my Phone f*cked up the battery detecting...
CM9 and CM9 detect the battery at 45% and then he Level instantly just drop to 0%...
I cant even restart my phone, so i guess the battery really went out...
So how can i fix, that the ROM would not detect it 45% but 3-4% ?
And let me fully chage my phone ?
Stock rom Always Detect it 100% and then randonly the phone shut down in random times (cuz it drops the level to 0%)
I've tried the "Fully-Charge, Fully-Discharge" But the ROM still detect the Battery wrong...
Even tried to delete the battery stats...
Any solution, or idea ?
I currently use CM with the built-in CM9 kernel...
I think its battery problem.use a new battery.ur prblm will be solved

How old is the battery? What charging cable are you using and what is the cable plugged into?
If the battery is more then a year old it could be 'tired' and not holding a charge correctly (trying another known good battery in your phone will determine this, as will trying your battery in another phone, and if it works well you may have more issues to deal with). If you got the phone second hand, you have no way of knowing the battery's history. Repeated overcharging is also not recommended, as well as leaving the battery in very hot places as it can damage the onboard circuitry in the battery.
Cheap aftermarket (non OEM) USB cables are not that great imo, they are generally not as well made and soon get loose connections, resulting in poor connectivity (charging with a bad cable can also damage the battery). Always use the original cable or a good quality aftermarket one, like Belkin.
Charging the phone from a USB port on a PC or laptop (and/or via a USB hub) is not as efficient as charging it directly from a wall mains USB adapter, because the power often gets interrupted. Ideally for the best charge you should turn the phone off and use a wall/mains socket USB lead, so as give a direct, constant, power supply to charge a battery. A typical full charge is done in two hours. If you charge this way and the battery still has issues buy a new one.

First of all, the Phone is manufactured in 11W41 (2011 Week #41) and the battery in 11W39 (2011 Week #39)
I use a tipical Micro USB charger which does not connect to the wall with USB but the cable directly integrated into the adapter...
And the phone's shipped official cable to charge throught my PC...
The battery worked fine before i forgot to delete battery stats and flashed a ROM...
After that, all ROM is getting fake battery data...
After using my phone i noticed:
-When the phone displays 70-80% charge, the battery actually have 10-15%
-When the battery reach 0% the phone not just jumps to 0% but the Phone shut down within a half second (as no more energy)
-When i charge it to 3-4% the phone show 80% again...
-So i can charge it to about 10 or max 15% when the OS detect 100% and does not charge it further more, which prevent me from properly re-calibrate the battery stats, cuz 10-15 will be always the max charge of the battery...
Now i'm looking for some kind of Mod / App that fake the Battery level to the OS (for example lock it to 5% and the OS continue to charge the battery) i know its dangerious cuz if i'm not aware i'll overcharge it and it will die permanently, but i have no better idea ATM...
Update: Sometimes after my phone dies from no remaining electron in the battery It displays 5% charge when i switch it on while connected to a charger (the only way i can switch it on) And starts to increase.. (5-6-7-8 etc..)
But sometimes it instantly jumps up to 70-80% if i think right when the screen switches of..
So i enabled "No-screen-off-whili-on-charger" and letit charging..
Will notice you about the result...

try reflash stock.ics ftf should fix this
Already tried, the Stock rom always showed 100% charge, and when the battery ran out, just powered off...
(Jumped from 100 to 0 instantly)
As i mentioned, in the reply you quoted, today it started charging from 0...
It went good, but somewhy, it just stopped at 26% and not a single volt went into the Battery...
As i Pulled out the Cable, the indicator jumped to 100 instantly...
Can you link several stock ROMs ?
I've tried with the 4.0.4 Android
but maybe the 2.3 can still work with it...

but i think theres some HW damage. even if not rhe battery maybe some config chip is broken or whatever on the board. normally flashing a stock.ics.ftf resloves all software issues, as its resets all stuff to factory..
anyway, here u can find links to other android versions: http://talk.sonymobile.com/t5/Andro...y-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389

One solution still, that my frind has the same phone as me, so when i meet him, he can charge my battery to really full and maybe when i insert it to my phone it might work...
My nexus said it was charging when i went to bed but now it wont charge or connect to the computer? help would be appreciated
never mind i flashed fire-ice kernel instead of the elemental x, and it started working...
Funny you posted this...
I've not had problems with it charging or connecting to a computer.
Although, I've had problems getting the damn thing to charge while I'm using it.
Even with it plugged into a 2.1A charger it usually keeps the same charge or even drops 1-2% while playing a game or whatever.
If I keep it at idle or in sleep it charges no problem. Not sure what the problem Is, I mean if it's inputting 2.1A which is limited by the Kernel to 900mA (Why that is-- is stupid).
I'm assuming that the device uses somewhere at the ~1.2A under full load.
I had that same problem
I never had the not charging issue until today
