Hallo
I make an extensive use of my new touch pro 2 as modem, so battery is drained very quickly.
Is there a chance to power the phone, by means of some special cable, without the battery inside ?
Many thanks
I would say this is possible.. But may require some heavy edits.
The reason I say this is because when I was running Android on here, I could remove the battery with it plugged into the wall and it would still run (not sure if that's healthy for the device or not, though).
Why not just use the wif router app and plug it into the wall charger?

If you don't have a wall charger handy I would think a USB battery pack would be able to supply enough juice to keep you going for extended periods of time. Get one that runs on AA's and just keep a bunch of Eneloop AA's handy. Works better if you plug it in to keep it from getting drained instead of trying to use it to charge it. Something like this one:

Here some clarifications.....
My internet use is mainly at home. So I have always a wall charger available. The reason I would like to power the phone without battery, Is because I've heard that charging battery while using it, may stress battery and reduce its life. Same result if you expose battery to frequent charge and discharge cycles. That is the reason of my initial question.
I've read that special power cables are able to do the trick, but I coudn't find anywere.
Thank for your help anyway.
I already posted this in another thread by Trbobuick, but I thought an new thread with a correct title would be of better use...
I just recieved the powerpack, and its not very beautiful, IMHO. The cut out spaces for the power button and the volume rockers makes it look a bit odd.
The material (and texture) used for the powerpack sadly doesn't look like anything on the S2. It stains easier than the phone itself, as it seems.
During charging with the S2 in the powerpack, the phone beeped every few minutes that is was fully charged. (Another user reported it did it only every hour). While you may sleep through only one beep, this powerpack will keep you awake all night. (I am on a stock rom)
And then, if the powerpack (disconnected from mains charger) has charged the phone, the phone has the "remove charger" notification, and this (until now) stays and seems to prevent further charging the phone by the powerpack. (Unless you remove and reconnect the powerpack).
Until now this Samsung Powerpack seems a badly (I am mild) designed thing, unless I don't understand the operation of the powerpack.
Its just an external battery, and more or less behaves as such. That there is a phone fitting inside this external battery seems more like a coincidence as intentional.
Not Happy.

I'm not entirely sure how the pack works.... you charge the pack and then the pack charges the phone? So essentially it's a portable charger that draws its power from its own battery?
Yes.
Its just an external battery with a USB pass-through (not all functions of the normal USB plug are passed through, such as HDMI) and this external battery charges your phone.
p.s.
It seems as the powerpack still charges, even if the normal charging icon is not shown.
When I check battery status it (allways) says 4 seconds on battery.....

Yeah it charges, I got 6 hours of medium use before the pack stops charging the SGS2 and it begins using the internal battery.
Battery meter is useless to measure this tho, it thinks it's still on the charger.
Aaaaaand, I gave up trying to charge the pack while the SGS2 was in it because:
1) It charges so very bloody slowly
2) The wake me up thing I get every hour or so
I charge the case on it's own now, thankfully I have a whole bunch of microUSB chargers. But really Samsung? It's not that you haven't had time to improve on the design, considering the SGS had a battery case too.
Mine arrived yesterday, wasnt exactly what I was expecting in terms of size.
As it adds as an external power source, battery stats are useless.
Ran it from 5pm yesterday and my SGII switched over to internal battery at around 5am.
Now charging as standalone to stop the beeping !!
I have a dock at work that I place my phone onto every day as soon as I arrive. I noticed at about 11 AM today that my phone was showing 72% battery, even though it should have been fully charged when I left this morning at 9 and had been sitting on the charger since 9:30. More annoyingly, it seems to be staying at about that level--it's not moving up at all. If anything, it's continuing to lose charge even as the icon shows it's charging!
I took it to a Sprint store, where they unhelpfully suggested that I have too many apps installed that are draining the battery in the background. I manually stopped most of them, uninstalled some that I don't really use, and put it back on the charger. It's still not going anywhere. I turned the phone completely off for an hour and charged the thing, and it had gained about ten percent (that seems pitiful, but at least it's charging?). It's back on the charger, still not really moving anywhere.
So what are my options at this point? I've never calibrated the battery, so maybe I need to do that. Other than that all I can think is that either the battery is going bad (but I have a feeling Sprint is going to insist "It's still charging" if I take it back to them and refuse to give me another battery), or perhaps the dock is not supplying the right voltage and hence it's not charging fast enough to overtake the power consumption.
What's bugging me is that I haven't installed anything in the past week that should be affecting my power consumption like this. Last week I had plenty of apps installed with GPS and bluetooth always on, and as long as the phone was docked it would eventually reach 100%. Now I have pretty much everything off, several apps I usually have running turned off, and several more uninstalled (including Lookout Security), and the battery is barely making any headway. I keep the screen on to a desk clock (because that's the whole point of a freaking dock), but that alone shouldn't be draining it faster than it can charge.
Any suggestions?
Sounds to me like its not getting enough voltage. When you charge it at home does it charge reasonably fast?

I never really monitor it, but I would say so, yeah. All I really check is that it's fully charged in the morning before I walk out the door.
The culprit might be my dock. It says it's designed specifically for the GSII but the cable itself looks to just be your standard USB-to-microUSB dock, other than a little bump at the bottom so that it's clearly aimed for bottom-charger phones like an iphone or SGSII. I suspect it might be supplying less voltage than the charger that came with the phone.
Is there anything I can look at (app or internal setting) that can tell me what kind of voltage the phone is receiving?
EDIT: Should also note that it's sitting on the dock now and it is at least making positive gains on the battery, albeit at maybe 1% every fifteen minutes. I really don't remember it being this slow before. Perhaps the dock's cable is cheap and is just crapping out over time.
USB charging is about half the speed of regular, wall socket charging. Invest in an OEM charger or one that has similar specs to an OEM one.

do you have the dock connected to a USB port on a computer/laptop or wall outlet?
USB charges at 150mah while most ac adapters charge at between 750-1000mah.
Well, when I used the my generic LG USB cable it took about 5 hours to reach from 0% to about 40% while shut. So, I changed the cable and viola, charging to full in less than 3 hours while working on it.
So, it seems that the charger is bad quality. Try using the original cable (if possible) or may be the original charger plug.
I guess that's the only solution, because there is no way that the phone is discharging at a faster rate than charging, except when it is connected to an external display. This is the only thing that I encounter where the phone goes dead after a while despite it is connected to the charger...
Yeah, that dock is a POS. I'm not surprised it charges slow as balls too.
Amusingly, my phone has been running on the battery since leaving work for about four hours with the screen off, and it's only at 92%! I must have uninstalled whatever was draining it so quickly.
Thanks, guys.
If you think it's an application draining it, try better battery stats in the market. Might not be the problem but it does help.

That's right. Use Original cable came with your phone.
I've experienced same thing when I tried to charge my D710 over LG micro usb charger thru AC outlet. The charging indicator was showing flash but actually it was not charging or charging speed was not enough to follow the battery usage.
I charged the phone all the night but in the morning it was empty!
Charging through the original Samsung micro usb cable, it never failed. But charging thru LG micro usb failed couple of times.
You can easily check a couple of things -
try to connect micro usb cable to your PC and set the USB mass storage mode.
If we use LG micro usb over samsung phone, it's not perfectly fit and data communication frequently fails. More importantly, Don't even try to odin your phone using LG micro usb.
It's not the issue of charger. It's the cable issue.
Do not use LG Micro USB cable for data communication, but if you want to use for charging, be sure that you hear the connection sound from the phone. If there's no connection sound, the battery won't last long even battery charging status shows the flash.
Hope this help.
I currently have the CM10.1-M3 build from 4/17/13 installed.
For a long while, I have been having major issues charging my Captivate Glide.
My original battery died. It was bloated. I called AT+T and they sent me a replacement. I also bought two high capacity batteries.
If I leave the phone charging about half the time little or no progress is made charging. Lat night I charged the phone for over 8 hours and the charge went from 10% to 14%.
Other times I will wake up after charging it all night and it will say fully charged, but then the instant it is unplugged from the charger, it will drop down from 100% to 20% or less.
Then once every 3 or 4 days it will actually fully charge. But even in that case the charging is slow at best.
I did a full wipe and re-flashed last night and nothing changed. I have tried charging in airplane mode, but that seems to make it worse. I have had a little tiny bit of success turning mobile data off, but otherwise I have tried everything I could think of with no luck.
Has anyone else experienced similar issues, or have any suggestions? Is this a case where I might need to replace the phone entirely?

I did notice a lot longer charge time when hooked up to USB on computer, on my car charger and hooked up to AC I seem to get a lot quicker charge...
What charger are you using?

I have tried a few different chargers. I mostly use a 2.1amp wall charger. I also have a 1 amp wall charger, and a 1 amp car charger. I have tried about 3 different car chargers.
I am really suspicious that the micro-usb port on the phone went bad and that I will need to get the phone replaced.
Charging with AC is gonna be alot faster then with DC. But as far as it being the rom I don't see tthat.. sounds like possibly a loose wire or bad connection when u lay ur phone down

Hello,
When I charge my Captivate Glide with phone powered up plugged in to the wall, using the supplied wall charger, I've noticed that the battery seems to drain quicker. This is with the original battery, I will be getting an extended battery for my phone. If I power the phone down then charge it in to the wall it charges quickly and seems to take longer draining. This does not happen when charging with the PC.

Bloated battery could just be bad - but it could also be due to overcharging. That's not going to happen unless there is a serious problem with your phone, or possibly a problem with the contacts leading to an incorrect voltage reading. This also may explain your problems charging and sudden jumps in charge %.
Clean your contacts well on the battery side and phone side with a pencil eraser, rubbing alcohol, etc.
I notice a big difference with whatever kernel is shipping with the current M3 cm10.1 build between a 500ma charger and 2amp charger, so I imagine the kernel is set for a 750ma or 1amp charge.
I have a battery / charging problem on my Gnex. The problem is that the battery won’t charge more then 60 %, drains quick and then the phone shuts down at 0 % ( in about 2-3hrs of use) and wont restart until recharged.
At first, I tought it was the battery so I bought one OEM on ebay. It did the same thing so I returned it and went to Telus store to buy an OEM.
Same thing happened with the new OEM. I then bought an external wall battery charger and charged the 2 batteries I have. When I put the first one back in the phone it said 12%?
I tried the second one which is the new OEM and same thing, its showing 12%.
I did a little test, I had 4.2.2 so I unlocked the phone and rooted (no more warranty anyway) I flashed back the ROM to ICS. No change.
So what I did next is I used the phone until it shut down at 0% and restarted it on the bootloader screen and left it on, on the bootlooader screen.
Well the phone screen stayed on for more then 3 hours, so I know the battery is good because there is no way that a 0% battery could power the screen for 3 hours.
So after it shut down from the bootloader screen, I charged it again, in the phone, and it went right back to 60%, I did try to wipe batt stats from recovery mode and battery calibration apps but no luck.
Is there a way to disable the auto shut down on the phone? The battery meter if definitely showing wrong charge stats. Is the battery controller part of the USB board or the motherboard?
The only thing I did not try yet is a custom ROM and Kernel.
Any ideas?
Sounds like a hardware failure... It's obviously not the batteries

I found where the Power Management with Switch Mode Charger chip is, on the motherboard! I wonder if there is some ways to access and modify the values of this.

For what it's worth, the same thing is happening to me. Charges to 64%, and it acts like it's only got a 64% charge - runs out fast. And I also tried a replacement OEM battery with no difference. I'm not completely convinced this is a hardware problem - though I guess it could be. I'm still stock Gnex (with the 4.3 upgrade - and come to think of it, this started some time after that upgrade). I was hoping it was some kind of kernel problem that i could fix by switching to CM. Anybody have any luck with that?
The same thing is happening to my phone, although I'm lucky enough to have it charge to 73%. Only realized the problem when I bought a new OEM battery and it stopped charging at the same 73%. I have a friend who has the exact same phone and will give her both my batteries to charge and see the results (with her phone then once batteries are reinstalled in my phone).
Outside of replacing the motherboard, would anyone know if there could possibly be a software fix? Has this happened to any other phone? If so does anyone know the results?
Thanks,

Sounds like a hardware failure in the phones' charging circuit. Since:
- no software change (ROM or Kernel) fixes it
- no battery change fixes it
Then it's obviously the charging circuit in the phone. Time to get a new phone!
Well I've confirmed for myself that it is my phone charging circuit that's giving me bad info on my battery charge. I installed both my batteries in a friends Gnex and both gave me 100% charge reading on my friends phone. I then re-installed both batteries in my phone and both came back with identical 13% charge reading. So to me this is obviously not a battery issue.
Since my previous post in July my phone has gotten progressively worst. So I have now come to the point where I either have to replace the phone's charging circuit or replace the phone all together. I would much rather do the first as any replacement phone via my carrier would require me to pay more monthly on my contract.
So would anyone know with certainty where the charging circuit is located in the Gnex? Is it on the main logic board or the USB charging board?
Thanks
