Anyone else got this? My battery should be fully charged in the morning with the green light on - but the battery is 91% (or 94% or 99%). Then if I plug the charger it jumps from 91% to 100% in seconds.
Just hope its just waiting few cycles to calibrate or something... :/
Yeah, it seems to sort itself out after a few charges.
same with mine, only just happened after the update
I have something else to share about battery charging after update. I usually charge my phone from my computer's usb port during the night.
However after the update USB charging is much slower than before. It would take about 4 hours to charge from empty, but since the updates it only charges with a rate of 13% every hour so it takes more than 7 hours to fully charge from empty.
Anybody else noticed this?

yeah, ive had these same exact issues. its so annoying. its just not worth charging via PC usb any more
The GTalk issue is out there again, not sure if its the culprit? I have unchecked the 'automatically sign in' and logged out, but it keeps turning on and logging me in by itself. Im sure its one of the reasons for the battery drain. Anyone else with this?
This morning it dropped from 100% to 88% in less than two hours without really doing anything with the phone...
this whole 'stopping charging till 90% once its reached 100%' issue is rediculous. I cant believe that HTC have added this to the update (cos it didnt happen before) for a phone where users rarely get a days usage out of the phone battery anyway! Now you even stand the chance of starting the day with 10% less charge than you should....rediculous!
if its something they want to include then thats fine, but at least give us the option of turning it off
This is from a german forum:
Let the phone empty the battery until it switch off for its own. Switch on again and do a new boot until the phone is switch off again. When switched off charge the battery completely with the original charger.
... and the 90% issue is gone
I have a second battery I never used before. Im going to put it to charge tonight - and let it do few complete full/drained cycles. Hope works ok.
Wonder if everyone else has the persistent GTalk on? I dont want it!! Arghhhhh....
I have the same issue with mine Desire after updating last week,just get the green light for a full charge and after a few minutes I check my battery widget and lol 10 % are gone.Any chances for fixing that issue?I would appreciate if anyone give a helpful advice.thanx in advance.cheers

The same here...
do we have new info about this issue ?
Is this such a huge issue then? I mean, sure you want it to show the correct %. But does it affect the total duration in any way?
The 10% can eventually level out when being used. I wonder if the device is at e.g. 30% it should actually be 40% in this case, or the 30% is actually quite accurate.
The % is an estimate to give a better representation how much there is left rather than just following the voltage drop. But in the end it will most probably be the voltage that makes the device decide whether or not the battery is empty.
Don't be silly, ofcourse this is a huge issue, did u ever seen such a issue on any other device, even devices of 5$ dont have this strange behavior.
Phone from such class to have such a problem, this is annoying.
And rather iPhone4 signal strenth issue i think here problem is software and it will be fixed
Comon, a 'huge issue'?! It's merely some % figure that's not shown correctly.
Oh well, I guess it's a compliment for the Desire then.. if 10% off is a huge issue, the rest can't be so bad!
Devices of $5 are really bad in showing correct percentages really. One part of the % goes fast, other slow and then suddenly fast again (you know, 1 out of 3 blocks left but flat battery in no-time, while the second block lasted hours and hours). Just because a device says it's 100% loaded, it doesn't mean it's actually correct.
That's why I wondered: Does it actually affect battery performance. If it does, then (and only then) you can call it a 'huge issue'. Otherwise I would just call it a minor annoyance. But obviously stuff like this might be personal eh!
But I'm quite convinced as well this is a software problem and can be fixed. I just don't think it will be very high on the HTC priority list
Ok, i agree its minor annoyance, but anyway it's annoying at least to me, you are right, this percentage may be fake, but for me it will be better if they show me real battery load
cheers
ps. i saw in your signature u r 1.15.405.4 - do u have this behavior on it ?
Well, the Desire is gone to be replaced now. But I didn't have this problem with my old Desire. Then that one got replaced (because HTC scratched it), and the new one did have this problem.
But now the Desire is off again because of weird touchscreen problem, so lets see how the new one holds up
I've read a bunch of threads but haven't found a solution to my particular problem.
I've had my Nexus since April, and all was fine until about 3-4 weeks ago when I noticed that no matter how long I left the phone charging it wouldn't go past 88%. Getting married in August and working a lot of overtime, I have been frustrated by this issue but have done nothing about it, so over time I've been watching as it was maxing out at 84%, then 80% then 76%, 74%, 72%, 70%...it now will not charge past 66% and by the end of the week it will probably be 62%!
So, I have tried three different chargers (one that came with Nexus, the one tht came with my fiancee's HTC One X, and a no name). I have replaced the battery (a friend has the same phone with a spare battery). Nothing changes. This is clearly not the "well it reaches 100% and then stops charging even while plugged in to save the battery" thing that most threads talk about. It's not the charger and it's not the battery.
It's the phone (or the software). I'm not positive I even understand what "rooting" a phone is so it's safe to say that it is not rooted. It is an out of the box Galaxy Nexus that has only had official updates (currently running Jelly Bean but the problem did begin before it updated from ICS).
I'm praying for a solution as I bought the phone in Hong Kong, and therefor cannot return it.

Well it's not exactly like I bought it from a mom and pop shop or from the guy with a suitcase on the corner. It was purchased from Fortress, which is a subsidiary of Hutchison Whampoa which is an international conglomerate that operates in the US, Canada, and all over Europe as well. Don't confuse Hong Kong with mainland China, there is no difference in quality between this phone and one purchased in USA
Did battery calibration help at all? I'm starting to think that either the software is showing a wrong percentage (which in case you can calibrate it) or you have to get it checked.

I downloaded a calibration app, and realized the phone needs to be rooted. The app said that it would only calibrate the phone when it was in a 100% charged state.
The default battery meter said 66%, app called power circle said 66%, and the battery calibration app said 66%

Ok you can calibrate the battery status by draining the battery until the power turns off and then just turn it on again (while charging obviously) and then charge it to the max and then hopefully it charges to 100%

Oh, ya I definitely did that, more than once, with both batteries. I let it completely die on it's own (which isn't hard as the battery life is noticeably shorter since it won't charge all the way). I also let it drain to 1% and then charged it full. I tried draining until it shut itself off and then charging it full while it was shut off, and then again with it powered on during charging. Whether on or off, it continues to tell me it is charging, but never reaches higher than the numbers i posted above (currently 66%).

you can still calibrate your battery with this app

just untick wait til 100% if your battery is still coming up odd
it definitely sounds like a software issue to me
I'm having exactly the same problem. My phone was purchased in a different country and had several different firmwares (we've used it for kernel development) so it's not under warranty anymore.
At some point I flashed the stock firmware (it was 4.0.2 back then) from Google's website and started using it as a normal phone. Everything was fine until at some point (somewhere in September) I noticed it stopped charging past 89%. After that I saw this figure go all the way down to 39% and that's where it is now. It charges to 39 within an hour or so, then the charging status while being plugged says "not charging". If I leave it like this it can go to 60 over a few more hours, in this case if I go into charging status I can sometimes see "Charging (USB)" which basically means lower charging current (seems like some kind of trickle charge situation).
I think that it started after I saw a different charging glitch (that one is quite popular on the Internet) - when the phone doesn't see that it's plugged I fixed that one with bending the USB "tongue".
I've tried switching the battery with a properly working GN phone - my device sees a different charge level than the working phone. The working phone had shown 95% on my battery and 90% on its own battery. My phone had shown somewhat like 35 and 30 respectively.
I've tried multiple different stock firmwares (4.1, 4.1.1, 4.2.1). I've tried full reset with data wipe and clean firmware load a number of times. I've tried battery stats reset, battery pull, full discharge (in bootloader and another phone) - nothing helps.
It looks like the phone detects the current battery charge incorrectly and while the circuitry prevents the battery from overcharging and turns off charging when the battery is at full capacity, the software for some reason sees 39% instead of 99% and thus turns off the phone when it sees 0 (and it's really somewhere around 60%).
The two things that I haven't tried were flashing a different kernel (CM? AOKP?) and replacing the USB port board.
I don't want to mess around with different kernels because I don't really believe that it'll help, but I did order the USB board.
I'd appreciate if someone with similar problem shared their experiences.
P.S.: Just took my *#*#4636#*#* battery info screen: it sees that it's at 24%, sees that it's plugged into AC and it's not charging.

Mine started soon after i flashed my first 4.2 rom. my battery info also reports similarly to what others are saying (good health, 100 scale, 3.9v). i just think its very strange that more and more people are complaining of this.
another side note, whenever im using my phone while its plugged in, the battery seems to drain pretty quickly (even though it is saying ac-charging). anyone else getting this too?

Hey, thanks for pointing out those threads, looks like they all describe the same issue. I guess, a moderator needs to unite them or something.
When I'm using an AC plugged phone - the battery drain seems to be of similar scale as charging in WiFi web browsing scenario. If I'm streaming a high-res video over WiFi, sometime the drain is higher than charge rate and it dies even being plugged, saw that a couple of times.
If I'm using it as a GPS in a car, it drains faster than it charges with a regular auto charger (not sure of its amperage), however I haven't checked this scenario before the problems with charge started.
To address my experience with the issues mentioned in other threads:
- I tried my stock battery in another gnex that doesn't have the problem - that phone saw a different charge level in my battery from what my phone had been showing. Also my phone had shown incorrect value for the other battery which leads me to believe that it's not a battery issue.
- I had the thought that dirt and dust in the connections might be an issue. I disassembled the phone (following this video https://www.youtube.com/watch?v=6sD6LRfJHSk), checked and cleaned all the connections (not with alcohol, though). Except for the inside of the USB port all the internals were pretty clean to begin with. The procedure didn't solve the problem.
Now, the only suspect I have remaining is the charging circuitry. I have ordered this part http://cnn.cn/shop/samsung-i9250-galaxy-nexus-microusb-connector-flex-cable-p-15348.html (also available on ebay) and will see if it will solve the problem. Luckily it's fairly easy to replace, requires no soldering (though it does require to disassemble the phone completely).

Really hoping you figure this out. After spending far too long trying to fix mine, I broke down and replaced it. It is currently a paper-weight. When plugged in it says it is charging, but won't go past 0%. I plugged it in on the weekend for approx 30 hours and upon unplugging it immediately shut down. I have an external battery charger and two batteries and I can charge the battery full and put it back in the phone and it will still say 0%.
If it means anything to anybody, this problem starting happening to my phone when it was in stock condition (hadn't been unlocked or rooted) but after it was updated to 4.2 through the standard consumer method of updating.

Well I've finally given up. I broke down and bought another battery on amazon (samsung verizon oem one) with near certainty it wouldn't help. It didn't. I've been running stock now and I'm going into the Verizon store tomorrow to see what they can do (if anything). I'm sure they will give me the run around though (oh its probably just the battery etc).

Same story for me. Exact same issue. Ive flashed roms (CM, PA, Unique, Minco) and the issue does not go away. I did change the USB board. It did not help. I think too that the circuitry prevents the battery from overcharging. Battery Indicator App says FULLY CHARGED even when android reports 0% charge.

I have the same problem. Ive replaced the board 2 times. It does not help
Got my USB board today, replaced it and it didn't help. Short of changing the mainboard, I'm out of ideas
I'm having this same problem. Purchases a Nexus off Craiglist the other day (with forwarning of this battery problem) and figured I could fix it easily with a new ROM or by wiping battery stats. Unfortunately nothing I try seems to have any effect. I've used different batteries and charged them fully with an external charger. As soon as I put them in this phone they read 64%. So Frustrating!!!!
I believe that any WP7 user that uses two batteries on one WP7 device, totally messes up the OS battery readings , and battery power expectation.
I used to do that in the past on windows 6, and I used different batteries on same device with different capacity without any problems.
On WP7 this is not possible. At least not for me and my Omnia7 .
After short period of time, battery stats will become total broken and batteries wont work at all. OS Readings will make no sense at all and OS will shut down while batteries are showing 45% charge.
To make it worse , the only solution is to hard reset your device and make sure that no different batteries are ever used again.
I tested this with original batteries, other brands, different phones and always ended up with the same results.
After short time, you have to do a hard reset just to get the OS to re-read the correct power capacity.
Re-calibrating the battery with depleting methods or other 12 hour charging methods are not working and not healthy. Removing the battery and other woo-do tricks are also not working. I am aware about this thread but I doubt that this method does something useful, not to mention that you still have to do a hard reset and wipe everything.
Is there a way to force the OS to reset the battery data without hard resetting the phone?
At the moment , any battery that I use, shows 9 hours only on full charge. And those readings are totally wrong of course.
There should be some resetting tool or calibration tool for battery data and readings.
Thank you,

WP7.8 on developer unlocked, Omnia7.
I seen battery callibration data somewhere in the past, then I mean answer is yes. But I could not remember, where it was, probably somewhere in register. Sorry for spamming, but it is a next drop in the sea of errors of WP7 OS makers, that are very poorly repaired due to Microsoft restrictions. I have nothing against proprietary, closed system, but such it must contain no mistakes! I use two batteries with the same capacity, but OS understands good only one of them, second one is very often unreasonably wrong measured immediately after insertion.
Thank you for your answer.
I have 4 batteries. (2 oem and 2 no name,) All of them on full charge will show 7-8 hours max. Tried almost everything for almost a month but battery stats are totally broken. Looks like I am slowly approaching to my 5th hard reset just to fix this. I was hoping for some "reigstry or file type of fix".

may be \Application Data\Microsoft\BATSVC\records.dat is what you're looking for?
I remember crazy situation with a totally new WP7 device. Battery was quickly discharged and turned off in factory default settings (3G on + WiFi on + GPS on), but I needed to send one SMS urgently. I took battery, held her for a moment in my hands and returned to mobile. It was worked, I sent SMS and device turned off again. Everything seemed ok, but phone repeatedly restarted after connecting to the charger! I had to remove the battery and charge it from an external source, because too small voltage does not allow to run charging everytime after booting before total discharging! It is really Smart Phone.

ultrashot,
Thank you!
Steps I took:
Disconnect from battery charger.
Go to settings -> Battery saver. -> Remember your % and remaining time.
Battery Status: 100% remaining time: 9 hours.
Rename the file "records.dat" to "records.dat.bak", (with "wp7 root tools") File is located at " \Application Data\Microsoft\BATSVC\ ".
Turn off the phone, remove the battery, press all keys for 20 seconds just to make sure that no electricity is left at all.
Return the battery and turn on the phone.
Go to settings -> Battery saver.
Battery Status: 95% remaining time: 1 day 2 hours.
Thank you again!

Hello, Now that the trik is explained, it would be fun if anyone could do an app that does this automaticly.
Greetings
Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.
Hi guys -
My 8.4 has been driving me crazy for the past week. It is not rooted, running the stock Samsung image. The battery percentage seems to be wildly inaccurate. I've read through many of the battery threads here (most seem to deal with the inability to charge completely), but I have noticed some that seem to resemble my problem. The solution seems to be to pop the back off and replug the battery. I have not done that, and frankly, I don't think that's the issue here.
Symptoms: Battery appears to drain unevenly - will drop several 10's of % instantaneously during mixed use, and sometimes level off again. I haven't found any runaway processes. Bottom line, overall less then expected battery life followed by the system shutting down. HOWEVER, if I then reboot, it will boot up anywhere between about 5 and 30% remaining - and will continue to run. Sometimes it will drain quickly again, other times it will run for several more hours. Sometimes if I connect the charger after shutdown, it will immediately jump to 40% upon reboot.
Experiment: Drain battery smoothly after a full charge by looping a local video, and track battery percentage and voltage. When system automatically shuts down, reboot (it pops back to 30% or whatever) and continue. Keep rebooting and running until a reboot registers 0% and immediately shuts back down.
Result: Battery drains VERY evenly and consistently. It's only the android percentage that seems to be erratic and cause the system to shut down. I've attached a graph of what I see. The spikes represent points where I rebooted. Blue line = battery percentage (left axis), orange line = battery voltage in mV (right axis)
So given this, I'm having a hard time believing it's a battery connection issue. My uneducated guess is that unplugging the battery works for some because it forces android to recalibrate the battery meter. I've been unsuccessful in getting it to recal by charge/discharge cycles.
Does anyone have any thoughts or ideas on what I should do next? Is there a way to force a recal of the 0% point without rooting? As a side note, I find it odd that my Nexus 7 simply doesn't boot when it hits zero - just shows a battery symbol. Seems odd that the Samsung let's me constantly boot the thing.
Any thoughts would be appreciated!!
Mike

Hi! I own a tab S and some users get this problem also on the tab pro. Its something with the battery connection to the device which causes the gauge to be all wonky. Usually problems like you described need to be replaced by Samsung. If you are under warranty, then they'll replace it for free of charge. Better to be extra safe! Hope this helps!

Thanks...yeah, I saw all the comments about the battery connection. As I said in my post, I'm still struggling to believe that it's a connection issue when the battery voltage - reported through a battery widget - is very reliable and steady. It's only the percentage that's wrong. Sounds more like a software issue to me. If it was a connection issue, I'd think the battery voltage would be all over the place too.
Frankly, I'd rather not send it in if I can avoid it (no service centers local). I'd like to explore all possible other options first. Any other ideas on how to force a real recalibration?
Thanks,
Mike

When your device is fully charged, My guess is to turn your brightness up to the max and open an app that's like intense graphical games or Google earth. As long its stresses your CPU and GPU. That should make your battery drain really quick and cause random reboots because of the meter. Keep doing so till it reaches 0%. Then recharge. If that doesn't work then I don't know. I've done that many times after I flashed a custom ROM so it would calibrate. Doing that would draw all the power out hopefully

Ok...I gave up. I've tried the drain thing multiple ways. I don't want to root the thing or install a custom ROM because I won't be able to use it on my company network. I called Samsung and set up a return. What really bothers me about this is that without an explanation, it's likely to just happen again -because again, I'm still convinced it's software related.
Thanks anyway,
Mike
Sorry to hear that. Please come back when your device is returned from RMA and tell us how it's doing...

Will do Calvin - thanks. For the record, I tried one more thing before I boxed it up. I reflashed the firmware with Samsung Kies3. It all went smoothly, and I had high hopes....but shortly after logging in to start setting it up, the battery immediately dropped from 99 to 88....so no luck. I'll be shipping it out tomorrow. I'll post my findings when it returns.
Mike
Well guys - I got my GTP back earlier this week. The actually fixed it in one day and shipped it right back to me. Unfortunately, there was no explanation or description of the repair on any of the paperwork or their website - so I have no idea what they did. Regardless, it appears to be functioning normally now. I fully charged it when I got it, and then ran it down to zero through random usage throughout 2 days...and when it hit zero and shut off, that was it. It wouldn't turn on again (which is what I would expect). I charged it back up, and it's working fine again. So far, so good.
Bottom line, I guess I had some kind of a battery problem, but it appears to be working now. As I said before, I just hate problems with no explanation - it means they are likely to happen again. I guess time will tell...
Mike
