[Q] Transformer stops charging at 99%? - Eee Pad Transformer General

Just got my second transformer yesterday, a 32GB, I charged it overnight.
I noticed that the charging stops at 99%, I unplugged and used it a little bit, it didn't charge at 95%(the task bar battery icon doesn't change). Then I unplugged and used it again, when the battery drop to 94%, it start charging again. The firmware is stock 3.0.1. I haven't upgraded it yet.
Anybody else sees this weird behavior?
Another 16GB model charges just fine with the same cable and charger.

Most devices do this or something similar to stop over-charging of the battery... but most won't tell you its stopped at 95-99% but just say "Charged"

That is exacly my concern. It only shows 99% not 100%. My other transformer simply says 100% when it's done charging ...

it's ok..99% vs 100% may have something to do with battery calibrations..

I hope so, I will upgrade to 3.1 and recharged it tonight and report back.

LiPos can take several charge cycles to get to full capacity. I wouln not be concerned until after a dozen or so charge cycles

Charging Weirdness in Android

So lately I've noticed that battery life is strange on my Vogue with android. When I let it charge overnight, I take it off the charger and it instantly falls to about 97%. At about 1 PM the battery hits around 30% so I plug it in.
Here's the weird part: it's only charged for a half hour and it's reached 80% according to the meter. After another half hour it will say 100%, and stops charging. If I take it off the charger, it will instantly drop to around 77%, and lower quickly. If it says it is not charging anymore, but I know it is not full, is it really not charging? Can I just leave it on and expect it to continue charging to the real capacity?
Is this just how it is? or is there anything to be done about this? I've tried completely discharging the battery a few times, but didn't really help at all that I could tell.
Curious about everyone else's experiences
Thanks!
I think I remember reading somewhere that Android reads the temp of the batt. to figure out what % is left....
Try this.... When your batt. is low, take it out and blow on the connectors for a few minutes... See if your % rises.

Trying this now... lol
Would I have to do this every time I want to get a full charge? seems strange. Maybe this woudl explain why it charges overnight - longer period of time the battery can cool down, charge up more, cool down, charge
how long should the vogue legitimately take to charge? Seems as tho mine does well within an hour...

Perhaps my battery has just lost it's capacity - it is around 2 years old
Here's what I posted about battery issues in the thread for my Kaiser build:
Battery issues are due to the driver. It was written months ago and AFAIK hasn't been looked at since... I know it has some bugs, here are the ones I am used to:
Intermittent charging
stopping at certain percentages (like ~70%) and refusing to charge
when refusing to charge also does not detect when plugged into USB/ADB
won't fully charge
reports different battery percentage than WM
sometimes jumps instantly from ~30% to ~4%
reports connected to computer when only connected to wall charger
repeated USB-connected notifications
battery becomes hotter during charging than on WM
I should add also that sometimes when the battery dies in Android it won't charge in WM until I boot the phone in WM and unplug and replug the charger.
If I want a proper charge, I just boot WM and wait ~2 hours. Much simpler than Android.

Gah, that's too bad.
When I charge overnight, I don't have problems. It's in the middle of the day when it isn't on the charger for too long that I have issues.
Thanks for confirming the weirdness though, at least I won't bother with a new battery (yet)

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.

Charging issue

There seems to be a bug, where if i leave the phone connected overnight on the stock charger and wifi is off when i wake up the battery is at 80% or less. My theory is that as soon as it reaches 100% it stops charging, has anyone experienced this?

This is happening to me as well; I've come to believe it's a faulty charger, actually. Or a charger designed that way. But the charger's fault regardless.
First occasionally, but now for a few nights in a row, I've found a phone plugged in overnight to be at 80% battery in the morning. When I look at the battery graph, it appears to have charged rapidly to 100% (or close-to), then started slowly discharging. However, with the battery use screen open, I also noticed that the status was rapidly changing between "Charging (AC)" and "Not charging", spending most of the time in the not charging state, despite a constant plugged-in icon in the notification area. This behavior persists regardless of wifi state and through many reboots; BUT, it hasn't happened at all yet (with just limited testing) when plugging it in through the adapter for my last phone (an HTC), nor does it happen when charging via USB. I don't know if the LG charger could be designed that way, where it stops when it's full, or if it's just a faulty unit that needs replacing. I'm going to try it on the HTC wall unit overnight tonight to see what happens.

I'm actually having a similar problem... For me I noticed that the screen stays on while the battery is discharging while on AC charging mode so it may be a different issue. It doesn't always happen but when it does, I'll be sitting around 75% when I wake up in the morning.

Just checking in - a few days later, it hasn't happened yet using the HTC charger.

Turns out this is caused by using a USB extension cable... it would say the phone is charging on AC but there would not be enough current going through. When I plugged the the stock usb cable in to the charger directly, it charged fine.

Nexus 4 discharging after reaching 100% on wireless charger

So as the title indicates, for whatever reason the nexus 4 is discharging after reaching 100% on the wireless charger. Now, this would be fine if it continued charging after it drains to a certain battery percent, but sadly that is not the case. When I take my Nexus 4 off of my wireless charger in the morning, I see that it has been 'on battery' for 7+ hours, and the battery is usually between 70-80% which isn't enough for me.
If it helps, here is some information that may be useful:
-My nexus 4 is rooted on 4.2.1
-My wireless charger is called "MoKo Qi Wireless Charger 3-Coil Charging Pad"
-I've tried restarting my phone, but the issue persists
-The wireless charger works at full speed with no issue (apart from the charger turning off when the phone is at 100%, and only removing and putting the phone back on it will turn it on)
Now, I've seen some threads where people say their phone isn't at 100% when they take their phone off, but they mentioned that their phone starts charging when it discharges to a certain percent (say, 95% or something) but sadly mine does not.
Any help is appreciated, thanks in Advance!
-Neutrino
Edit: If it helps with anything, the charger makes a faint 'ticking' sound every half a second ONLY when the phone has reached 100% and continues ticking until I remove the phone. The ticking sound persists even while the phone is draining overnight on the charger. I have also tried to test if letting the phone reach 100% then draining the battery while it is on the charger by leaving the screen on changes anything, but it seems it doesn't matter whether the phone is 'awake' or not.

I don't understand the problem. Are you reporting fast discharging of your phone after 100% has been reached? Or you are reporting that it doesn't start to charge again when the phone drops from 100% to 95% or whatever?
In the second case I suppose that your Charger works in this way, and nothing can be done.

It would be the latter, the phone doesn't start to charge again when the phone drops from 100% to like 80-90% overnight. And something CAN (and HAS) been done, I hooked it up to a $10 Woods Model 50001 Indoor 24 hour mechanical timer, and made it turn on/off every 30 minutes during the night/morning. It works perfectly now, my phone is always at 99-100% when I wake up since it doesn't idle for 7+ hours, maximum it ever idles is 30min.
I was just wondering if it was an issue with all chargers, or is it just an issue with my phone... I'll test it with my brother's nexus 5 some time and see if it still happens (without the mechanical timer).
