Hi,
I have an SGS GT-I9000 (T-Mobile UK), I had stock ROM 2.1-update1 a week ago (this was my Mum's phone, now mine). As I already have one phone I decided to root this and install CM7 using the latest wiki instructions (Heimdall, ROM Manager) including CWM, this rooted, unlocked, updated.. Of note, my phone does not have the 3BR, I have not yet fixed that with Odin, I have made a 301K Jig. The phone also has a forced upload mode immediately displayed while phone on and pressing Home+Up.
After installing CM7 (phone wasn't fully charged during install, a friend was helping me and it was taking too long to charge again after failing to unlock the network via adb for some time) the battery was not full, I used the phone for a while and plugged in later. The problem is that it got to ~54% and didn't move for an hour or so, battery would quickly drop a percent or two again. At this point the iPod wall socket displaying as "charging (USB)" in About.
I reset the battery stats in CWM which did nothing to the current battery level reading of 54%. I flattened the battery with GPS, speaker, WiFi tether, etc. got to 1% then turned off after a while, would not turn on again. So I charged with an HTC wall charger, which forces the phone to be fully awake thanks to CM7, also showing AC as the source this time, but although the battery quickly reached 10% and 30%, it did not pass 66% after more than 12 hours charging.
I am happy with the usage (~day) I get from this phone, but I would like it to say 100% occasionally.
I will flatten the battery again, then plug in to switch on, followed immediately by reboot into recovery (an option in CM), then I will leave it over night ~7-8 hours charging in recovery, and perform another stats wipe. I have read that without 3BR I may never get my phone on again (low bat boot loop) if it gets too flat, I hope that doesn't happen (didn't last time, before I read that).
Any help?
Also, there is one other thread about never fully charging: http://forum.xda-developers.com/showthread.php?t=780340 but the OP says that it displays 100% but keeps on charging anyway.
Just run it through a full charge cycle 2 or 3 times, its just lost is head,it comes back,...........im on insanity cm 022.....happened to me

Still not charging
Hi, thanks for your advice, I have now completed several full cycles and with patience I am getting 100%. The problem still exists though, it take 24-26 hours to charge from 0 to 100% even with flight mode on for half of that time, longer if not. I am using an AC charger (as recognised in the battery menu). I do get about 12 hours of light usage from the phone, but will lose the first 10% while browsing the internet even while still plugged in.
Any further advice would be greatly appreciated. (I have tried a couple of different wires and plugs, some say USB, others AC).
S
P.S. I am considering finding a stock ROM and fixed 3BR partition and reverting back to a better than before stock, unlocked, unrooted system.

Baring in mind that batteries never charge to 100% dude even when it says it has, this is a safety feature to prevent over charging and exploding batteries, I'd go through the cycle again, let your battery go dead, try switching it on to make sure the batteries dead, then whilst off, charge your phone till full, then unplug and plug in again to make sure its full, then if its full boot immediately into recovery and delete battery stats, repeat these steps another 2-3 times bud

Cheers, I can't charge with the phone off though, another reason for going back to stock maybe (or removing clockworkmod). I would have expected batteries to trail off near the limits, but the charge rate is fairly consistent throughout. I shall keep cycling the battery and resetting the stats though, so far no improvement, it's just an inconvenience to be without a phone every other day.
I know the feeling bud and I know its tedious, but keep at it and it should get better pretty soon so long as you stick to the cycle

I had a S i9000 with a cracked screen. I have replaced the screen and since I put the bits together the phone no longer switches on
If I place in the battery charger the battery appears on the screen and chargers normally but when I try to switch the phone on nothing happens.
Could please somebody give me any suggestions?
Is there any alternative way to switch on the phone?
Thank you
This may seem obvious but leave it on charge for 30 mins unplug then try turning on

Battery now 100% e vibrated when reached 100% but still NO power
is there another way to power up apart from power button?
Is it showing the charging sign when plugged in?

Yes. I see the battery picture and the dots flashing
I was wondering if anyone else was having this issue.
I've charged my Nexus7 overnight on three occasions. Plugging it in before I went to bed (~1AMish) and getting it on my way to work (~8:30AMish). Out of those three times, on two of them, when I went to get my tablet the unit was powered off. I know for a fact that when I plugged it in, it was on, and no one touched it in the meantime.
The most recent occasion was this morning.
On all three occasions, the unit still had 40-50% battery life left.
On two other occasions, I've charged it during the day for a few hours, and it was fine.
Additionally, I've never had the unit turn itself off overnight when it wasn't plugged in. And I'm using the charger/cable that came with it.
Lastly, the first occasion was on the stock kernel/rom, and the second was on the motley kernel (but stock ROM).
So it seems like something is causing the unit to power itself off if it's on the charger for too long. This is concerning, because the only thing I can think of is that it's overheating and shutting down as a protection mechanism.
Any thoughts or ideas?
Plugged mine in for the first time last night at 11:30. Slept till 8, hit the power button and everything was fine.
Basically, no issues here.
Was it fully charged when you switched it back on? I ask because I shut mine down for the overnight charge last night (plugged into a laptop, not the wall - there's only one socket near the bed and my battery-sucking phone gets that juice), and when I woke up it had only gone from ~30% battery to 55%.

I had this happen to me on the first unit I had... I was actually using stickmount to transfer some data and left the usb adapter plugged in for about an hour and when I picked it back up it was DEAD.... I could not get it to boot up at all until I did the recovery (power/volume) method and then everything was fine but I returned it anyways cause of a defective screen... I am now on my 3rd unit from Sam's Club and I think I might have a keeper...? (Knock on wood) :fingers-crossed:

Yes, it was at 100%.
Keep in mind that charging via computer's USB port takes much longer. Maybe your laptop went into sleep mode and shut down power to the USB port?

Nope, my fiance's phone was plugged into the same laptop and it was fully charged in the morning. And as a general rule, I've never known the computer to automatically sleep while on AC power, even when the screen is closed.
Thank god i'm not the only one experiencing this. My nexus 7 always seems to turn off after I leave it overnight plugged in for charging. I thought it was a kernel issue but i've switched kernels and i still experience it. Still unsure as to what is causing it.
Same here. Its odd it only seems to be for an extended period of time. Also my battery was indeed fully charged. Should I exchange at Sam's?

There is nothing else wrong with the tablet. I have a feeling it could be some sort of hardcoded feature where if it notices that you're plugged into the wall charger with 100% battery and the tablet is in deep sleep for a certain period of time, it automatically shuts down.

Ikr. First time it happened to me I was like wtf? It might to stop the 2 amp charger from overcharging? My unit is fine, I think the sound is just right. I might get that squaretrade warranty though.

Well, I feel a little better that I'm not the only one with this "problem".
The question is, is this a "problem" or a "feature". I guess we won't know unless we ask Google/Asus (good luck getting that answer) or enough people respond saying that it happens to them too. But if people start saying it does not happen to them, it makes it more likely to be a problem....
This happens to my phone due to overheating. The tablet does run hot when charging. See if there's a temperature logging app and run it overnight.

It would be nice if it would just cut off the battery charge and run directly on A/C. But I guess I would rather have it power off than explode.
isnt bad to charge it overnight like i believe from 1% to 100% chrge is like almost 3hrs fully chrged.. i just alarm myself for 3hrs to check if its fully chrged already then unplug it

True, it's not good to constantly charge the battery once it's full.
Most devices however have a built in charger kill switch once it reaches that point. Laptops for example will switch to A/C power and only start recharging the battery once the level drops to ~95%. I believe my phone does this as well (SGS2).
I guess I'm OK with it turning itself off, assuming that it really is a safety feature. My main concern was something was wrong. It would have been nice if they mentioned this in the 100pg Nexus Guide eBook though .

I want to add my own observation -- mine was almost fully charged, I plugged it to my computer's USB, turned the screen off, walked away. A couple hours later, the Nexus 7 was turned off. But I was shocked to find that, pressing the power button couldn't turn it on. The first thought came into my mind was that my computer did not charge the Nexus 7 and the battery ended up completely drained. So, I plugged it to the wall charger, left it on for a day. 1 day later, I tried to turn it on again. No, it didn't work. I was panic and decided to Google about how to reset and checked if I could wipe it and sent it back for a replacement. I found that pressing the power, vol up/down button at the same time can force a reboot. I tried that and bingo, it booted into the bootloader. Before I wiped, I decided to try to boot back to the Android OS. Surprisingly, that worked. I was happy and decided to ignore this incident. Then, today, it happened again. This time, I immediately used the power + vol up/down trick to reboot, and that booted me right back into Jelly Bean. I checked the battery status and it's fully charged, which meant my computer was charging it all along. For some reasons, the Nexus 7 would just turn off itself. And, in my case, pressing the power button alone would not reboot it.

Sounds like to me that it's hard locking, not "powering off", and you're forcing a reboot. Long-press of the Power button should do the same thing.
I can't say I have much to offer in regards to this issue, but am I correct with my observation that everybody experiencing this issue has experienced it while their N7 was plugged into a computer of some sort for an extended period of time? Has anybody had this happen when plugged straight into the wall outlet?
Here's another update with an interesting 'twist' since my last post.
I've charged it twice in the meantime. Once was, again, overnight, and I woke up to find it powered off. A simple "on" press brought it back on.
However, on Saturday, I used it heavily and was down to about 40%, so I plugged it in around 11AM. I meant to grab it around 3PM when I went out, but forgot about it. Got home late, and went to look at it at about 11PM (12 hours later). It was charged to 100%, running off the A/C power, and still on.
This is weird, because if I leave it plugged in "overnight" for 8 hours, it will almost always turn off sometime before I grab it. But when left plugged in during the day for 12 hours, it stayed on. I wonder if it handled the situation different based on the time of the day???
Yesterday my phone shutted because my battery, I connected to my car and charged a while, I got out from charging and using 2-3 minutes more and battery died again. When I got home I connected it to AC power and powered on, It was working without problem. I left my phone maybe 1 hour charging and when I took it again it was dead: screen dead, no life signal, just the led blinking slowly when connected to power (either AC and USB)...tried to take off battery but nothing. Today I connected it to PC and windows has recognized it but cannot identify it (on the PC the classic USB device not recognized error with yellow triangle on top) and the led is always blinking.
Any idea? should I have to buy a new phone?
thanks

Try Running some POST tests. As in, Power off your device and wait for few seconds. Then Press and hold your power key and your volume down key. You should be able to access your Bootloader. (If you have Rooted your device, you could access your recovery and clear the battery stats although your device's condition seems peculiar/critical). Its worth a shot If you ask me.
I have already tried it but nothing, cleared dalvik and battery stats..I cannot understand whats going on. Now phone is working again but it cannot maintain battery, I mean I kept it in charge all the night but when I power on the phone it shuts down just when it starts android (thats strange because I went to a store yestarday and tried a new battery but it didn't worked, when got home I tried to power on it again and it started)...this is driving me crazy!!
edit: I turned it on, plugged in AC charger and phone after some minutes told me that (I don't remember the exact message) power needed by the phone is more than the charger could provide...
edit2: now it is on and it is charging (USB) and it doesn't charge more than 21%...really strange
Odd that this hasn't been mentioned but perhaps try a different usb cable? Different port? Seems obvious but you never know. Cables can deteriorate.

I have tried 3 different cables and 2 different computers...same result. I have flashed a new ROM, plugged in for charging and now is stuck on 15% battery (5 minutes aga was 16%, it discharges while plugged in).
Ok maybe here is a solutions:

What do you think about?
I was flashing my Xperia T with flash tool and there was an error. Now I can't turn on my phone. The red led is blinking while trying to power it on. Vol up + power on also doesn't work (red led blinkinking). When connecting to pc flashtool stops on "For 2011 devices line, be sure you are not in MTP mode". What can I do?
First try to charge it for a few hours to see if it comes back, then you can try to repair via PC Companion or flash again

Already tried that and it's the same.
Yur battery is empty. You need to recharge. So open phone take battery out and charge it external. When battery is full just flash normal.
That is the reason why you should only flash if battery > 50%

He has a T so the battery is not removable....(Not without difficulty anyway)
Just leave it plugged in for several hours, or even better overnight. That should do it, and if it does not, then try and remove the battery
Now the red led is switching on/off every few minutes while on charger.
Just leave it it will boot soon

I have opened the back cover, disconnected the battery and after few minutes i have put the phone on charging. Red light appeard but after a while it went off again so i have measured the voltage. It's going from around 3.08V (red led off) to about 3.25V (red led on) and after that point red led is off, the battery is discharging and the process starts again. What can I do?
when did you do this?
Did you follow the advice above? In all cases I have heard of this leaving the phone on charge for 24 hours has fixed it. Plug it in, leave it alone, come back tomorrow and try to turn it on. (Maybe even hole power and volume up together untill it vibrates 3 times and then turn on)
Yes, I was charging it more than 24h and it was the same. I think I need to charge the battery external.
give it a go, and if you have the battery off you may even try and change it.
Thats what i told you. You cannot leave it charging. Chargemon is a software which can only start idf ROM is ok.
Just takr out battery and buy a cheap chinese external charger. I know R has builtin battery but it is no problem at all.
You REALLY have to charge it with external charger or another Phone with working software
