Strange charging problem since Vzw 2.3.5 update? - Galaxy Tab General

My Verizon GT7 was working and charging great until sometime right after the 2.3.5 update...but now it's having some odd charging issues.
I am NOT using the original Samsung charger. That got lost almost a year ago.
But, I have (for two months) been using the charger from my TouchPad which is also 2A. For the ~9 months prior to that, I was using a 1A HTC charger. Both of these chargers worked perfectly fine (fully charging in about an hour or two...and charged overnight every night)....until the 2.3.5 update.
Now, it charges VERY slowly regardless of which charger (or computer) I use. The status always says discharging. And the (status) battery level is not in sync with the (notification bar) battery icon.
I just dont know if that is a very odd coincidence or not. Could the firmware REALLY have changed the charging requirements/functionality?
I did a factory reset. That didnt fix it and I still havent installed anything or even setup any accounts on it.
Plugging in to a computer - the charge indicator always shows.
Plugging in to 1A charger - the charge indicator sometimes shows.
Plugging in to 2A charger - the charge indicator never shows.
Yes, this is completely backwards from what you might think and both chargers still work perfectly with other devices.
But, it does charge at the same slow rate with all three - like 2-3% per hour. The status says discharging with all three. And the (notification bar) battery icon and numeric battery level status are still out of sync. The (notification bar) icon is usually about 20-30% higher.
I have the original Samsung cable as well as a third-party one and both function exactly the same.
Right now the (Status) battery level says 46% but the (notification bar) battery icon is clearly over 90%. One or more of those is obviously not right.
I really dont want to be w/o it for two weeks sending it to Samsung if it really is not a hardware issue.
This is, and always has been, a non-rooted stock Tab.
Also, the large battery icon (when the Tab is off and plugged in) seems to be more in sync with the (status) battery level. So, it's just the notification bar icon that doesnt match those two. After getting it to 100% on both, the notification bar icon stayed at "full" until the (status) battery level dropped below about 70%.
Anyone have any ideas and/or experience with this?
Thanks!

Ok, as it turns out, 2.3.5 DOES change the charging requirements!
I went and spent $14 on a real Samsung charger and....its charges properly!
WTH.
Looks like what Samsung has been saying for a year now "that you must use the Samsung charger" was them being proactive until it was implemented in 2.3.5
For 10+ months, the other chargers worked perfectly fine. Now, only a Samsung charger does.

Anyone having charging issues?

A friend of mine just picked up a Droid X today and he's having problems.
First, the charger it came with doesn't appear to charge, there is no charging indicator light.
I attempted to use a number of USB chargers, the first from my HTC Hero, another from an iPad, and a third is a cheap Chinese AC charger with a USB port that I picked up for my EVO.
The only charger that turns on the green light on the top is the cheap Chinese one.
If I plug it into my computer, I can also get the green light to come on, but it doesn't appear to be charging it. When the phone is on using the cheap charger, the phone appears to work, but says on the lock screen to plug the phone in.
Further, the lock screen is not responsive. We let it charge with the phone off for about a half hour with the green light on, the phone boot up and had a little bit of life and the screen did work, then it suddenly turned off and won't boot past the Motorola logo (just flashes for a couple of seconds then disappears.)
So, whats the verdict? Hardware problem or is anyone else experiencing this? The phone did completely die, so I wonder if that caused a problem of some kind.
Do you have a Green light when charging with the phone off? Does the light flash red when it's on and charging?
Thanks for the help!
I plugged it into my home computer and nothing happened vs. being able to charge my computer and nothing. Although the phone was about half way charged before I plugged at work, vs 10-15% at home.
Mine didn't charge while plugged into my netbook, but does charge while plugged into my PC, and definitely charges while plugged into the wall charger.
Update: After using the wall charger and fully charging it, I connected the Droid X to my computer and it now syncs up. Maybe the amount of battery power matters?
I don't think the green blinking LED is a charging indicator. Mine charges without it....but I notice when I was charging it the first time, it was going off when I had an unread text message. Is everyone sure the green LED is supposed to be a charging indicator? Mine's charging right now according to the bar on top when I turn it on while it's plugged into my computer.
I'm having a charging issue with my car charger.
When I plug it in to the car the audio volume drops to almost inaudible and the voice commands don't respond anymore.
This is with all the volume sliders set all the way up.
I have to reboot the phone in order to get it to work again.
I've charged it connected to my PC at home and work and it works fine with those.
Wow, the OP totally describe my problem i had too. I went back to Verizon and got another battery. My first battery wouldn't charge above 50% and the second came with 80% and we tried charging it at the store and it never went higher than 80%.I read on another forum that the charging indicator only reads at every 10% intervals, so that may be the problem. The rep and I at Verizon was watching it to see if it would move up to 81% so we would know it was working(beside the bubbles moving animation) and it didn't and we gave up, I will see what happens when I charge it tonite with the AC plug for the first time.
So the green LED light is not a charging indicator. Apparently, there is no charging indicator at all.
We left the phone off and plugged in with the stock charger, no light, but it did gradually move up.
I did some searching on the Motorola forums and another user ran into the same issue, he said that leaving the phone off and charging it for an extended period of time solved the problem.
I have no idea what the green light meant when it was plugged into my cheap Chinese charger, it must have been nothing.
It wasn't a text message or any other kind of notification since it was on only when the phone was completely off.
Before he left with the phone it was up to 90%. A brief press of the power button brought the phones battery state up, but didn't boot the phone.
Hope this helps anyone else with issues. Just plug it in and let it sit overnight.
I had a similar issue the first day.after overnight charge all seems normal for day two.

The only charging indicator is the lock screen part if you just turn it on it will tell you at what point it is charged.

It will occasionally show 5% intervals when it gets below 20% (I've seen 20, 15, 10, and 5% intervals).
I've noticed my phone doesn't like charging from a computer while the battery is really low. Once it's had a little bit of a boost from the wall charger, it will charge fine off the computer.
I just changed to a new one today.a friend of mine is having the sand issues. As so did i. It seems its not the battery its a short on the ground on some phones. Its pretty awkward but it has only been a handful from a batch of thousands that were released. So were in good money.

Is this good or bad?
I have no problem my phone charges fast and the battery lasts forever, my problem is i have dead pixels and they seem to be increasing the longer i have the phone, sucks that i have to wait on a replacement, i hope i don't end up regretting this purchase

When you said charge fast you're referring to wall charge? Car charge? Or usb charge?
Stock X
Hey guys,
Figured I'd swing over here and give this a bump for a buddy of mine. Seein if this may be a slightly common issue.
The situation(for him): All on stock phone NO ROOT
- No charge on wall/home charger. Shows charge indication but does not actually charge whatsoever.
- No charge using PC usb cord to charge.
Again everything is stock and not currently running any app killers or really anything out of the ordinary as I can tell. The only thing he has purchased and is running that I am aware of is Launcher Pro. The issue has been brought to the attention of Verizon which is his carrier and he just received his 4th phone! Honestly thats the only reason I'm posting an inquiry into this hear. A simple google search results shows others with similar issues(posted link at bottom). He has purchased a new battery and wall/home charger along with another USB cord. All 3 phones he has had produced the same issue with all of the charge accessories(4th phone just received so no tests as of yet, but i put money on it doing the same thing). Verizon has been willing to replace every phone so thats not a problem but seriously! Is that the only answer?
any help is appreciated in advance

There are two charging indicators, no lights! One is on the status bar, you'll see a lightning bolt through the battery meter, and on the lock screen it will say charging as well with a %.
Absolutely, yes sir. Both indicators(lightning bolt in battery, and battery charge indicators) light up and show charging. Although once phone is unplugged it will keep whatever the charge level indicates for a random amount of time usually between 1min-15mins then the battery indicator drops immediately and shows an almost dead battery. As in charge shows 80%, unplug and within mins phone shows 10%.
Also:
- There are no other indicators of charging other than those mentioned (as it should be).
- The phone connects to PC just fine for mass storage. Files transfer with no problems.
thanx again!
So... which one is it? First you say no indicators, and now there's indicators but it just doesn't hold charge. is VZW replacing the phone or the battery? sounds like a bad battery to me.
My apologies you are correct *edited post* i meant to say it does show charging as in you see the lightning bolt and everything even the battery icon fills to show a "fuller" battery although that stat drops almost immediately after unplugging.
As in replacements they replace the phone and battery as well. I know its the 3rd phone so far with the same problem.

phone thinks it is charged.

I dont know what caused this to happen, because i havent flashed anything new on my phone or made any changes for like a week now, but today when i got home from school and plugged in my phone, a few seconds later i get the messaged telling me that it is fully charged, even though the battery on the status bar says it is at 20%. i tried wiping the battery stats in cwm but it didnt fix it.
Possibly dirty usb port/connector. Otherwise, turn the phone off to charge it. If it still doesn't charge right, it could be that the battery went bad.
oh lol i cant believe i didnt realize this. i just got a new keyboard and i had my phone charger plugged into the usb port that is on the back of they keyboard, i shouldve known it cant charge off of that i was being stupid hah. plugged it into the computer and it works fine.

The phone will say it is charged when you plug it into a USB port with too low of a current rating.
I do not know what the cutoff threshold is, however I have a variety of USB ports and adapters that I charge my phone off of and some of them work great, but a couple of them have extremely low current ratings and the phone just says "charged" because it is not seeing enough power go into the battery.
This might be considered a bug, if there was a way for the hardware / charging drivers to measure the strength of the USB port the phone is attached to instead of solely looking at the current flowing into the battery.
Hrm. Weird that it would report charged when it doesn't get enough current to properly charge.
On a related note - I would also recommend doing a deep drain / charge cycle about once per month, to calibrate the battery charge sensor.
- Charge your phone to 100%.
- Then discharge it down to 0%.
- Then charge it back up to 100% via the OS.
- Turn the phone off, and keep it plugged in to the charger. A green battery icon will appear, and indicate when the battery is fully charged to 100%.
- Reboot the phone into recovery, and wipe battery stats.
Doing this about once per month for any Li-Ion battery will help calibrate the battery charge sensors on the device, giving you more accurate battery charge stats.

Battery draining on the dock

I think this is getting quite critical for me, and I have seen a few others having the same issue. I kept my dock charged all weekend(solid green light), and last night took it off charge closed lid and put it in my bag. Today, I opened the TF and installed the awesome Battery widget from the Apps section, and it says my dock is at 3%, and my TF at 97%. So in a matter of 14 hours, the dock has been drained with the TF being idle and screen off.
Link to the battery widget?

Was the tablet on the dock when it was charging?
yes. the tablet charged first and then the dock charged.

FYI: In a recent "test" I did with 3.1 the dock battery lasted 30 hours from green light to flashing red (orange) light (I didn't have the great battery widget at that time. I just installed it!!!). This is with 4-5 hours of moderate use (navigation, email, some youtube), 10 hours of standby with wifi off and the rest (15 hours) of standby with wifi on.
This means around 3%/hour battery drain while on standby.
Joël.
Which is unacceptablet. the iPad, and the Nook Color lasts easily a week in standby.
Hey all, first off, thanks for the link-age to the battery widget. I can finally see what's going on with my dock battery status....and that status is NOT good
I posted in another thread that I had charged my dock as soon as I got it (before connecting to the tablet) for 18+ hours, and I never saw a green light. After that, I connected it to my tablet running Primordial 3.1, it offered to update the dock FW to 0209, and I allowed it to. It said update successful, and Settings confirms the dock is at v0209.
Problem is, now that I can see my dock battery status with that widget, it shows only 37%. My tablet is at 100%, so I figured the dock should then take the charge from the official ASUS mains charger, but this doesn't appear to be happening. As soon as I plug in the charger, the widget shows "Dock Status: Charging", then after 1-2 secs, changes back to "Not Charging".
The dock light is solid orange while I have it "charging"/plugged in, and I have NEVER seen it turn green. When I disconnect the charger, the orange light on the dock flashes infrequently, telling me that it has less that 95% charge. I am not sure if there is something faulty with my actual dock, but people reported that the v0209 FW fixed most issues. I just wish I could get both battery statuses to 100%!!
I wish ASUS did a better job on this dock. I know that it is a groundbreaking product here, so bugs are expected, but since it is hardware and I only have 14 days to return it to the store I bought it from, it would be good to know what the beep is going on...
Any thoughts, suggestions, comments would be appreciated!
Thanks in advance...
We may still be waiting on the battery saving fix from Asus. They've mentioned the dock is draining too quickly (especially in standby) - haven't seen an improvement even with 0209 upgrade so hopefully we're still outstanding!
The "mobile dock battery saving mode" under settings -> screen seems to help a litle. Lost ~30% overnight on dock charge, and dock has just hit 3% after a good 4 hours use so far today.

Thanks for that Highland3r...but may I ask, have you guys ever seen your TF dock hit a 100% charge? I'm still puzzled as to why mine is stuck at 37% and the battery widget shows that the dock is not charging.
Also, what is the supposed process when the dock and tablet are joined, but OFF of the charger? I would assume that the dock charges the tablet until it runs out of juice, then the tablet battery would decrease?
Funny because when I have none connected to the charger, but combined, my battery icon does not show that the tablet is charging. Maybe in this case, the dock battery + tablet battery enter some sort of parallel mode, which combines the draw from both (as one big battery?)...No idea here, but I still think something is wrong if my dock won't show past 37% and others have (possibly) seen their dock charge to 100%.

Sorry I can't give you any useful comments other that I have a similar problem. After one successful initial charge (successful meaning the light turned green), the dock will not completely charge anymore. I had the dock by itself on the charger for 11 hours and still had the orange led. Unplugged the charger, docked the tablet and immediately got the flashing orange.

Yup, dock hits 100% charge.
When combined but off AC, tablet remains at 100% charge until dock hits ~3% then the tablet battery drops.
Looks like, once the tablet hits 100% it no longer shows the charging status, just shows as full until it drops down to ~95%.
When charging, the tablet charges to ~100% first, then the dock charges up.
Have you tried charging the dock alone (i.e dock not connected to dock) overnight and see what the charge shows the next morning?
Here's my experience today with the dock... Took my dock and tablet off charge at 7:00am this morning. Started using it at a Google AdWords seminar at 9:00am for taking notes, email, doing Google AdWords stuff, etc. It's now 2:30pm, and the dock is at 27% remining. The tablet is at 100% remaining. So, that's 5.5 hours of solid use, and the dock still has over 25% remaining. If it keeps up, I should get to just about the end of the seminar at around 4:00pm before I start using the tablet's battery.
This seems pretty good to me.

Yes, I did in fact charge it alone for 18+ hours as soon as I got it, before ever connecting it to the tablet.
Right now I'm running more tests, and as both devices are coupled, OFF of the mains charger, my tablet is NOT receiving a charge at all. I ran some battery-intensive tasks to get the power level to drop below 90%, but the dock still never seems to charge the tablet (I don't see the battery icon change, nor do any other indicators show that the tablet is getting a charge when docked). Still says the dock is at 37% power, which I've never seen change after getting the Battery Widget, so I'm thinking something is wrong with my dock.
BTW, did you guys update the dock to v0209 while on Primordial 3.1? This is what I did, and while I suspect the FW was not modified by Roach, it should have flashed fine (which it did say after I performed the dock FW update). Although, as I did the update, it stayed at 0% for a while, then immediately said "Update Successful". A bit odd, but it still shows v0209 in the System Settings, and appears to work fine. It's just this battery madness!!
Will give it another day or two, but then might return it to the store before my 2 weeks are up.
Thanks again for the feedback all...really helps to try and figure out what's going on...
I've run some test, and to sum up, with the tablet docked with the keyboard, I've lost 16% battery in one night with the tablet TURN OFF ! (and not in stand by mode) !
Is Asus aware of this problem ? Is a fix on the way ?
Thanks, and sorry for my english !
_Believe_ my dock update came from a Modaco release - HR4 or 5 maybe.
Just to clarify - the dock constantly shows 37%? Doesn't drop lower and never increases? Seems a little wierd - would expect some battery drain of the dock due to the "other" issues.
You maybe best off trying an RMA on the dock, or contacting Asus and see if they can suggest anything.
One other thing to try (just to rule things out) is to run the following command via terminal emulator on your tablet (you can probably use ADB via a PC too if you wanted)
If you can post (or PM) the output - these two entries look to contain relevant information on Battery Status etc.
Try pulling the dock whilst running the logcat (you should see new entries on keyboard remove and keyboard dock, try the same with charged vs non charged too)
Code:
logcat BatteryService:D DockManagerService:D *:S
Lsst night, another test on the drain rate of the dock. At 11:45 PM, dock was at 61% and tablet was 100%. Today at 6:45 AM, the dock was at 27%, tablet was still full. So in 7 hrs, it drained 34% or 5% an hour on idle.
Is that consistent with what others are seeing?

Yup pretty much seeing the same. 30% drop overnight from a full charge
Hey Highland3r,
Thanks again for your help with this. I saw your post about the logcat BatteryService filter elsewhere, and I have been running it since last night (I wanted to post it before bed, but fell asleep on the couch!).
Anyways, it is attached as a .txt file so as not to clog up this thread. I did not clean it, so it has a fair amount of lines, but you will notice that my dock did drop down to 36%! Unfortunately, the tablet also goes down to 90%, so this is why I fear there is something wrong with my dock, as it should be keeping the tablet at 100% until the dock reaches 3% (or 0%).
By looking at the log and analyzing the STATUS parameter, it seems to me that:
Status = 2 (means charging)
Status = 4 (means not charging)
Status = 5 (means full batt?)
My "dock_status" appears to reflect the same, but you will notice "dock_status = 1", which shows a 0% level (this is when I was plugging, unplugging the dock from the tablet).
Anyways, I know it's tough to figure out what's going on, especially since your docks seem to be working quite nicely. I can't imagine that it would take forever to charge the dock, but the funny thing is that it finally dropped 1%, but is still NOT charging my tablet. I also do not see the tablet in charging state when both are connected, but not being charged from the mains.
Thanks again for your help, it's very much appreciated. I think for now, I will leave them both connected to the mains charger, and see how long it takes the dock to increase past a 36% charge. Otherwise, it's going back to the store I got it from 3 days ago for a new one.
A question for those of you who have docks that do charge correctly.
How warm does the wall adapter get when the dock by itself is charging?
I know when I charge my tablet by itself it gets very warm, almost too hot to hold. When I charge my dock by itself the wall adapter is barely warm. Maybe this temperature difference is related to why my dock will not get a full charge. Something is telling the wall adapter or preventing the wall adapter from outputting the correct power.

Phone wont charge over 85%

Hi all.. My Evo Shift 4G seems to have developed a charging issue.. I'm not sure if the phone is not reading the voltage from the battery properly or what.. Basically, my phone will not charge over 85%... In other words -- it never reaches 90%+ on the phone, which would typically cause the charging indicator to change from amber to green.
I've watched what the phone supposedly sees with 'Battery Monitor Widget'. Currently, the phone has been on the AC charger for about 7 hours... The phone reports 77% charged, 32.1 degrees C for the battery, 4024mV. I've watched it during the charge cycles, and when the battery is low, the current is definitely being applied to the battery -- around 500-600 mA. When it gets close to 70%, however, it starts ramping down the current.. Right now, at that 77% level, it is showing 0mA being applied to the charging circuit.
I have 3 batteries -- two HTC original batteries, one about 2 weeks old, the other from March.. I also have a 3rd party battery.. All of the batteries behave the same in MY phone.. If I throw the batteries into a couple of friend's HTC phones (one has a Hero, the other a MyTouch 4G) -- their phones report the charge at 100%.
I also have an external charger -- if I charge the batteries in that fully, my phone shows 85% charge, while my friend's phones will show the batteries at 100%. Likewise, if I put their batteries in my phone once theirs are fully charged, my phone will show it at 85%.
Anyone know how or if I can correct this?
Thanks,
Rick

It is rooted.. I get the same behavior on CM7 or the rooted OTA 2.3 update by x99..
I've tried clearing the battery stats.. That has not worked.. I believe it comes down to a problem with how my phone is reading the voltage of the battery..
Worked for me...
I had the same problem but the it could charge to 93ish% percent, not 85. I fixed by clearing the battery stats, setting the screen to never go off, and left it on overnight (while I'd been using it all day), recharged it to full while it was off the next morning, and unplugged the charger and reinserted it until when I could plug it in starting with the light green. Following, I turned it on while it was still plugged in, downloaded the battery calibration app from the market, and calibrated it.
Afterwards, I've been able to get the same outrageous battery life that others claimed they got on roms like evervolv and miui, and been able to charge to full. See if this works for you.
Have you tried a different charger? Say if you are using the wall try a usb or if using a usb try a wall. Just a suggestion don't know if it'll work.
EDIT: Looks like I need to follow my own rules and read everything fully. Sorry for the ignorant post it'll prob be no help!

I've tried charging via a number of different chargers:
1) HTC AC Charger (5V/1A)
2) Computer USB (5V 500mA)
3) Palm Pre AC Charger (5V/1A)
4) Palm Pre Car Charger (5V/1A)
5) Aftermarket AC Charger (5V/1A)
I think there may be a problem with CWM. I tired the wipe battery stats a few times (7) and it seems like it didn't do anything. Then I downloaded an app from the market called battery calibration, wiped with the app. I think it actually worked with the app, as my run times went from about 8-9hrs to well over 24. Hope this helps - Viperspike
From what i understand, charge to 100%, turn phone off and charge a little more, reboot, wipe batt stats and unplug. Run all the way down to zero (phone shutdown) and restart one more time (it should immediately turn off) Then plug in the charger, and reboot. Once on the charger make sure it charges uninterrupted until it reaches 100% the first charge.
Thats the problem.. I can never get anywhere near 100% -- 85% is the top.. At that point current drops to 0mA and the charging circuit turns off.
I did send a support request to HTC.. This is their response:
You were having issues with the battery life on your HTC EVO Shift 4G. You mention that you have tried another battery but you cannot get the LED indicator light to turn green or the charge percentage to go above 85%. You state that you have tested your two batteries in a friend’s MyTouch 4G and HTC Hero. Both devices show 100% when there is an indication of a full charge. Unfortunately, there might be another hardware related issue causing this to occur so I would suggest you consider a repair request for your Android device.

[Q] Critical battery icon showing when powered on.

I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
