TP2 Not charging to 100% . . . Anyone else?

Okay, I'm seeing a couple of issues.

1.) When charge my TP2 in Sleep Mode, it will eventually get to 100%. BUT, it appears that the charging stops (as it should) and then begins using the battery without ever kicking back in.

EXAMPLE: Phone reaches 100% @ 4:30am. I wake @ 6:00am, look at phone and is reads 100% UNTIL I unplug it. Then it immediatley drops 5-7%. Power settings tab shows device usage & stand-by time equaling 90 minutes: the amount of time from 100% charge to unplugging.

2.) When I charge my phone in Off Mode it NEVER fully charges to 100%. And it never resets the Power Information tab info. It would seem to me that when it's completely off 7 not checking emails, etc, that it would charge fully and much quicker. Not the case with mine.

I am running the most recent versions of NueBattery2 & NuePower/Backlight. Tried a hard reset & restored my data. Same issue.

Lastly, it happens with both the Standard VZW battery and the Extended VZW battery, fyi.

Thoughts or suggestions are appreciated.

I would say hardreset, WITHOUT installing your BACKUP you made. Maybe its something you installed. Either way that sux. Just hardreset and ONLY INSTALL YOUR contacts and if you setup email set it back up. Then run it for a day or so with nothing installed and see if that works.

mine is bone stock with respect to the battery (no special driver cabs). when the phone is OFF it does charge considerably quicker, but never reaches 100%. i have to turn the phone on then let it sit plugged in another 10-15 before it hits 100. i found that to be kinda odd too. but i think it has to do with the charging info reseting and such.

however i do not experience the immediate drop. i have read that with those 1% drivers the high numbers, like around 95-100 are inaccurate. therefore it may just be showing that it has dropped, but in reality it has not.

i feel the stock drivers, despite the 10% resolution, are accurate throughout the whole range, which i like. not sure if you need to hard reset anything, hope you haven't already, as mine is stock and i get the same "issue" if you can call it that

you need to let the battery completely die. (not just 10%) then fully charge.

Thats what I thought, OP needs to recalibrate the battery. That is always the first thing I do on my new phones/laptops. And I also do it about once every 2 weeks.

never completely drain a lithium ion battery... you'll do more damage than good. lithium batteries have no memory effect, so trying to condition them is useless, and unnecessary.

1st generation maybe, but the ones in any cell phone for the last ~5 years, need calibrated from empty.

(granted if you hooked up a led or small motor directly to the battery contacts and ran it to 0volt, then you would have problems) the phone will only drain to a certain level, beyond that the pwr-good signal is invalid.

like i said, lithium batteries have zero memory effect, so conditioning a lithium ion battery is useless. conditioning a battery is an old school method used on ni-cad batteries to avoid creating a memory effect, thus lowering the battery capacity. i know it's hard, but you gotta shake them old habits.

it's not conditioning the battery, so much as calibrating the phone to the battery. and I think it's actually better that way the phone doesn't try to overcharge the battery, even thought the circuit prevents this, the phone still tries.

No, this is not entirely true. Draining the battery completely, occasionally, will not harm it. It is only harmful if done on a very regular basis. When you completely drain a Lithium battery once in awhile it it resets the calibration so that the reading you get is more accurate. This is much different from the old NiCad batteries that were conditioned to accept a full charge when fully drained. The same experts who tell you that it is harmful to regularly drain a Lithium battery are the same people who tell you to drain it on occasion to re-calibrate the readings.

Also keep in mind that the readings that cellphone show for battery level are seldom acurate. Being off by 5-7% is probably pretty normal.
