xda2i Battery :S

you may had this topic before, anyways.
it had no power at all the backup battery was empty sow as the main one. i stick my xda2i charger in, red light shows on the top right of the handset, left it for about a day, picket it up the next day and only the backup battery is 100% :S it turns on every 20 mins i can use it for about 3 mins and it turns of again. help please

sounds like u got a buggered battery mate,
are you charging it using a mains charger or USB only?

noooooo please dont say that, and im using a mains charger
how much is a new battery?
edit: i have a usb thing aswell
the phone is almost brand new

theres two imputs on the phone one on the outside, one on the inside (back of the phone) maybe the outside imput is for the backup battery and the input inside the phone may be for the main battery? but they have diffrent sockets and i only have the one for the backup battery i think.
is that correct? anyone?
thanx
max
edit: so many veiws and no posts?

ok, i found out that it charges the main battery through a usb and im doing that, but it wont charge on the charger :S and when i take the usb out the power goes down like every 3 minutes a % goes down. may be im running something on the device i dont know about? very strange surprised to see such a machine fail its duties. :/
O2 needs to fix themselves
thanx

check the task manager you maybe starting the camera when you take it out of the cradle also what do you leave running in the back ground tapping x in the corner only minimises the program it doent stop it

how do i know whats in the backrpund?

I could suggest a couple of things but I think the easiest course for you to take would be to back up your files and programs (if you need to) and then perform a hard reset, once you've done that leave it to charge overnight. Make sure that your cradle is powered NOT from your computer using USB but from a charger plugged into the wall alternatively you can simply attach the adapter (that came separately to your charger and plug it into the bottom of your phone. The charger charges BOTH the backup and main battery there are no separate "inputs" as you put it. The connection is located at the bottom of your phone beneath the joypad.
I run bluetooth and use wi-fi on my IIi throughout the day as well as make and recieve about 2 1/2 hours worth of calls, My GPRS connection is more or less constantly on and when i'm out and about in my car (approx 2hrs throughout the day) I'm using the 2i as an MP3 player outputting sound through the car speakers. I sync my phone once in the morning and it stays on the cradle for about 10minutes. My battery basically lasts the whole day, by the time i put it on charge at about 11:30 pm its at about 21%

thank you for ur reply's
one more thing this is a stoopid question but how do u turn the phone of?
i tried pressing the on/off button located top left of device but the light just goes out, and i leeve it at night and in the morning the battery is dead im not running any programs.
thank you

press the icon on th etop toolbar which displays your reception, select "turn on flight mode", that will turn your phone off

after i press turn on flight mode nothink happens it just says turn of flight mode (wireless off)

i think i need to get a new battery the percent just goes down every 3-5 mins

Trying to charge phone while it's off automatically turns it on

I noticed today while I was trying to get maximum charge in minimum time that after I turned my phone off and charged it, it automatically turned on. After I noticed this while it was still plugged in I shut it off again and much to my dismay it turned on again!
I'm on the HTC 7 pro, anyone else confirm this issue?

Phone will not turn off if USB charging/syncing; must use AC charger. Another alternative is to buy a second battery & wall charger specific to that battery; I have this setup for my Samsung Focus, but use it infrequently.

Would you mind testing something?
Turn off your phone, plug in the AC charger and see if the phone automatically turns on automatically?
Then if it does turn on again shut it down again while it's still plugged in to see if it turns on automatically again.
Thanks, I'm trying to see if this issue is unique to my device so I can report it as a bug.

Windows Phone 7 works this way. I was a bit surprised too, but the explanation from MS was that the charging circuit in the phone is software-controlled, and in order for that software to run, the phone must be on.
Yes, I know anybody with a modicum of software design experience knows how lame that sounds, but that's the "official" explanation. You *cannot* turn off the phone while it's connected to external power.
The good news is that while charging, the WiFi is left turned on, so if you have a WiFi connection, you're not using 3G data in this scenario. That was my primary initial concern (but not the only one).
Brad.

So since it's software controlled it must be possible to disable it through some option.

if you disable it, you will lose an option to charge the battery...simple as that

I guess this is yet another feature I enjoyed with WM that I can't (hopefully yet) enjoy on WP7.
I don't understand why you would make a purely hardware thing like charging into software...

Well, I don´t really undestand why is it such a problem, you can still turn the airplane mode on, this way there will by no cellular transfer, and put phone into sleepmode, if you do this, what do you think, by how much slower you would have your phone charged compared to turning it off? 5 minutes? Well that´s an achievement...

I wish I had two identical devices and I could run an actual test on this but I can only use my old TP2. I've always been under the impression that if your device is charging while it's off that it charges much faster than if it is on (consuming power) and trying to charge at the same time. It's always made intuitive sense to me that that's the case.

unless there is some sort of software based charging optimization involved.

P6810 suddenly won't turn on

Anyone come across this? I put it on standby last night after reading a bit of my book on it, and it had around 50% power remaining. This morning, it was totally unresponsive; pressing the power button does nothing at all. I've charged it for 12 hours in the meantime.
I've done the following all with and without the power attached:
- Pressed and held power for 15 seconds through to a minute
- Pressed and held volume up with power to attempt to get into recovery for up to a minute
- Pressed and held volume down with powerfor up to a minute
- Pressed and held power while touching screen (read that one off another forum)
I guess potentially it could be on and in a crashed state and unresponsive to the power, so maybe in a weeks time when it runs out of juice, I'll be able to charge it and power it back up, but in the meantime, I'd welcome suggestions.
A few weeks ago I updated it to the official ICS build that was released, but did the update myself rather than using KIES, as KIES didn't even recognise my Tab's firmware original version. It's been absolutely fine before the update, and since. I only mention it because I've read about the Samsung build of ICS being prone to self bricking itself, but I couldn't determine what the symptoms of this vulnerability were.
Thanks for any help offered,
Will

did you try connecting USB cable and plugging it into your PC? did u get any activity? can ADB recognize your tab?

I think your tab just ran out of juice and the battery's protection circuit has kicked in. Try taking it to an electronic shop and plugging in different chargers preferably one with an output more than 2.1 amps to kickstart the charging. Plug it in and wait till the charging animation starts.

Had the same problem while on holidays. Once the battery goes below a certain level, you won't be able to charge it through USB any more. Instead you need to use the wall charger.
I think it's bad enough that the 7.7 doesn't have a micro USB port, but things like that are just stupid and Samsung made a big mistake here. It don't think it's the same with the newer tablets though. It's also not possible to just buy cables or chargers for this strange Samsung port, so when you forget your wall charger at home at some point you won't be able to use your tablet any more.
As long as you charge with the USB cable early enough, you can avoid it though.

A few months ago I experienced the same thing, the Tab just wouldn't turn on anymore.
I tried all there is without any luck.
Contacted amazon and they replaced it with a new one in less than 48 hours.
So far not Problems with the new device.

I have the P6800 and this morning I took it off charge. Put it into standby and only used it for about 20 mins then left in standby all day. It had about 95% remaining when I did so.
Picked it up this evening and the lower left area of the screen was warm and it would not switch on. Didn't think of the ADB idea but will try this next time but I had to reset it and when it powered on tonight after the reset, it was down to 15%. Within about 2 mins of checking stuff it was down to 3%.
Something is running when it is in standby but as I can't switch it on I can't check with BetterBatteryStats or CPUState to know what is wrong.
It does this every day. I am tempted to do a factory reset and reinstall only limited software.
Dave...

I see this thread is a little old but this has just happened to my P6810 too. A pity nobody reported back what the end result was.
My device had at least 95% battery last night but today I can't get it to respond at all, I've tried the wall charger and still nothing.
Anything else someone could suggest for me?
Edit. I tried getting anything from it connected to my PC but it couldn't find a device there. However I then tried it on the wall charger again and now get a blue battery icon, quite big, with a five step animation indicating that it is charging.
No idea how it went flat as the battery on this lasts a long time assuming the screen isn't on. When it boots properly I'll have a look at what the most recent apps I installed were as it has only done this once. Before this it has been perfect for the three weeks I've had it.

This is the infamous Sleep-Of-Death issue that is randomly experienced by myself and other users here, usually happens when WiFi bugs out due to weak signal

hhmmm, interesting.
I was having trouble with wifi just before this happened. Both my GS2 and this have been claiming to connect to my wifi but aren't actually getting an IP address from it.
I can't remember if it was last night or the night before but I manually set an IP address, the signal strength is fine as my abode isn't very big.
After it has recharged I'll have a poke and see what I can find, thanks for the reply.

So my device seems to be working fine again. It had gone SO flat that the date and time were incorrect!
After I could power it on I had a look at Better Battery Stats and nothing looked wrong so I have no idea what happened. None of the apps I'd installed the day before it played up had long wakelocks and weren't running when I turned it off.
For reference they were:
My Tracks
MyTrails
Google Earth
AndSMB
I'd turned both of the GPS tracking devices off before I turned it off for the night.
It hasn't played up since but it hasn't been long so I'll see what happens.

Yeah, the sleep of death is incredibly annoying. Honestly, the GTab 7.7 is a **** device. Samsung made way too many mistakes and won't do anything to fix it.

A similar thing happens to me every once in awhile. The way i check to make sure everything alright is to see if it boots into download mode. I just leave it plugged in for a couple hours and it eventually comes back on.

this is why my 7.7 is the last tablet/phone from Samsung i'll never trust them they are just bombarding the market with new devices and leaving the old ones to dust

^thats what I thought too but that gs4 is really tempting. I've heard worse about HTC in that regard anyways so that why I'm not going with the one.

Finally.. i bought Sony xperia Z.
I'll sell my galaxy tab 7.7. I.m very disappointed with samsung.

Unbelievable! ... this trick still works ... thank you very much for you help ...

^^ yo, this 'trickle charge' trick did NOT work on my (long) dead P6800... any other suggestions??

Quite strange because my Samsung GT-P6800 tablet was fully charged, it went completely blank dark as if it was off. To my amazement, SMS keeps dropping and calls kept coming in. Yet it is still as blank as though the tab was off. I pressed the power button and the volume up bottom for it to reboot. It rebooted without the screen coming up. It has been blank for two days now. What could be the cause? And what possible solution can be given?

Problems with wireless charger

Hi, i keep getting continual issues with my wireless charger.
there are 2 main issues i keep getting:
when i put my phone on the wireless charger quite often i will have to place it on the charger twice for some strange reason, this has happened for a long time now, if i place it on once, often nothing happens, so i then have to take the phone off the charger then place it back on and it will then realise its on and start charging.
The second issue i keep getting a lot is, sometimes when i place the phone on the charger it may start charging and then instantly say charing has been paused, then instantly start charging again, then instantly pause again and so on.....
Often i have to restart my phone to get it to charge properly, sometimes even after a restart it still does the same thing and i end up giving up and just plugging the cable directly in.
Does anyone else have the above issues or know how to solve them?
Is it a dodgy charger?
Thanks
James

I had the same issue with my previous s6 edge and found that setting on the screensaver in display allowed the wireless charging to function proprerly even tho doing this turned my phone into a hot one.
Then I discovered that (I don't know which kind of wireless charger you own, I have a samsung one (ep-pg9201) with a green/violet ring on the base with green in idle state and violet when charging) when the charging state is turned off and the screen displays "charging has been turned paused", moving a bit the phone or rotate it until the ring turn violet resumes the charging process.I just didn't need screensaver anymore.
I've replace my s6 edge by a s6 edge + and I'm still in the process of calibrating the battery but I found that usb charging is damned too slow, taking ages (4, 5 hours to gain 20% of battery) so I've not try yet wireless charging but only fast charging. I just hope the guy who sold it to me didn't screw up the battery and it's lifespan.
Anyway, on my S6 edge I've managed to reach 4 days on a battery charge, I' not sure I'll reach this with the edge + as this phone has real issues in that department.

Samsung T295 shuts off unexpectedly - Battery mod

Hi all,
I have modified my T295 to run directly off of the 12V in my car.
Basically I got a Buck LM2596 3A Step Down converter and dialed it in to exactly 4.0V to mimic a almost fully charged Li-Ion battery and hooked it up directly to the battery terminals, skipping the tiny board that comes with the battery. In other words, straight to the mainboard.
The tablet works perfectly as a car stereo connected to the Bluetooth Amp and doesn't have any problem, but once every 3 days or so it suddenly shuts off. Sometimes I enter in my car and it's already off and sometimes I'm driving, it suddenly gets a completely black screen and then shuts off. I can turn it on immediately after, but sometimes I need 2-3 tries.
Maybe it's kernel related and triggers some sort of brownout? But this doesn't make sense to me, since I can stress it and it doesn't turn off.
It's Android 9, rooted, debloated and decrypted in case this helps
Thanks for any advice!
