Charging the new Battery for HTC TP2 - General Topics

Dear Sir,
I bought a new HTC Touch pro 2 and I need to have the right advice regarding the first time charging the battery since in the manual theu said 3 hours and one of my friends advised me to leave it on the charges for 8 hours.
my question to the experts is as follows:
1-how many hours you advice to keep the new battery on the charge?
2- For next time charging, do i need to keep it till it lights green ?
3- when I am supposed to re-charge it ( till the battery reaches 0 % or 30% )?
Please advice
Regards,
ZongoL

On my experience no matter if you charge it all night or charge only a few while, after 3 or 4 years you will have to replace your battery
So use it as normal in the way you want and enjoy!

Charging - need some technical help
Hello everybody,
Since the best phone ever died (or better: drown) on me (HTC Universal OFCOURSE!). I had to look for a replacement and TP2 seemed like the best of bad things. LOL!
I noticed that the wall charger had a 5V -1A(mpere) output. My (standard) car charger has a 5V - 0,5 A output. So I got the notice "your current power supply... not enough ...close some ...."
Besides the fact that e.g. tomtom uses more than the charger can give, i was wondering :
is it BAD for my battery charging at 0,5A instead of 1A ?
how much A does a laptop give when charging my TP2 trough USB port?
HAs this got sth to do with the fact that in some programs there is an option like "do not charge while connected to PC?"
I know this is more of an offtopic question, but I hope there is somebody with enough electrical knowledge to help me out!
THX!

XDA2 Replacement/Spare Batteries

I'm researching batteries with a view to getting the best life possible out of an XDA2 between recharges.
What replacement/spare batteries do people use and what is their power (mAh) rating?
What other things can people tell me on this?
I'm not averse to back-packs etc.
TIA
I have one of the batteries available on eBay. Seems the same as the original battery. I carry the spare in my belt case.
I got mine from www.pdamods.com and have been using it for three months now, must say better than the original and in fact looks like an original !!!
I have three batteries. One came with the unit, I bought another from the same shop, the third I bought 2nd hand. All appear identical and all 1200mah. I swap them through my XDA II every week or so so that they each get drained and recharged regularly. When not in use one is on charge in my desktop cradle in the office, other in my briefcase.
All seem to last about the same amount of time.
Must admit though since buying an integrated car kit for my XDA II (plus GPS) I do not have to swap batteries as often.

You can find batteries at 1400mAh, same size as the original and officially 20-30% increased autonomy.
Battery question
Thanks everyone for all the help you've given to me in the past. I have a couple battery related questions:
1. I just got a new battery from PCPockettechs. It is rated 3.8VDC 1200 mAh. The current battery in my XDA II is rated 3.7VDC 1200mAh. I have not tried the new battery yet and am worried that the extra 0.1VDC might cause it some harm. Does anyone know or have experience with this difference? Am i worrying for nothing?
2. The extra battery charger that is in the cradle - it does not appear to be working (the light does not come on). Does the XDA II battery have to be fully charged before it starts charging the extra battery? Does the cradle need to be plugged in to the AC (I have the EU cable which I cannot use) before it will charge or can it just be connected via USB as I do now?
Thanks again,
Sean
Hi,
When I purchased mine from www.pdamods.com it worked straight out of the box. Unless it is completely flat it should work even if charged for a short while, however you should charge it for 18 hours on the first charge.

As far a I know you have to use the AC adapter. USB won't work.
Not true, I charge it with the USB, however NOTE it does take longer
The MDAII charges on USB only too.
Not sure about charging an extra battery (that is what the question is about I think)
thanks guys. Yes, the MDA II or XDA II both charge in the cradle just on USB... however, will it also charge the extra battery just on USB? I don't think it will unfortunately.
On my other question: does anyone know if the 0.1VDC difference will make a difference? The battery appears to be the right size, shape, same connectors, etc. as the original battery - the only difference being this 0.1VDC.
Anyone with some good electrical/technical info that they could share would be great. It would put my mind at ease - or stop me from making a big mistake!
The MDA II charges on USB (in the cradle).
But for the extra battery to charge in the cradle you need to plug in the power (and then the light will turn on!).

Charging via PC

Hi guys,
I know if you unplug a charging phone in and out a lot it kills the battery, however my question is (as this was a big battery killer on my nokia n95) if I plug my touch pro into my pc and it has charged, will it then run purely off external power?
On my n95 it would charge, use a tiny bit of power on the battery and very shortly charge again. Obviously if my battery dipped again by a whole bar id want it to kick in the charger but that was crazy.
I'd like to leave my touch pro plugged in a lot for activesynch etc and charge at the same time so it would be nice to know if it's going to kill my battery.
I find that when the battery is charged the USB power will stop charging it. I charge overnight with my PC off on USB and come back and the full charged status is on.
Your PC should be able to provide 500mA through the port if the Touch Pro requests it, however the standalone charger is rated at 1A (1000mA) so if you are worried about using your device while charging then perhaps use it with the external charger.
I see no reason why your battery wouldnt be charged adequatly by the USB port though, generally you would be using less than your are getting from the usb port.

erm... where did you hear that?
no it doesn't
maybe you mix it with the car ignition eating too much gas if you do it a lot?
Well, it used to be that way with the old NiCd batteries. Nowadays it's not an issue anymore.
My apologies, whilst lithium ion's don't have memory they do still lose overall power by each charge and discharge, even if it's not a complete one.
my 5 years old LOOX 720 disagrees with you
also my 5 year old HP IPAQ disagrees.
battery is as new and i charged it whenever i wanted.
same situation with my HTC Artemis, i bought it since the first day it went on sale and battery is as new!

This issue has come up so many times ..... i post again a link to a website with details on how to maximise a li-ion batterry. It clearly states that it prefers small discharges, with full discharges in every 30 charge cycles.

Charger advice needed

Hello all.
I cannot use the original HTC Desire charger (because of the plug, things like that).
Anyway, I have a charger which fits the Desire, from my old Nokia E52, but I am scared to use it.
This is the charger specs:
OUTPUT: DC 5.0V/ 1200mA
And this is the charger photo
What do you guys think, should/can I use it to charge my Desire?
Can it cause damage to my device or battery in the long or short term?
Thanks for your opinions all.
That will work fine, I have used a Nokia 1200mA charger on my N1 numerous times.
Thank you very much, that made my heart calm
I noticed that charging it through the USB it takes very long time, and I risked shortly to charge it with this charger. The difference was day and night.
But I wasn't feeling comfortable at using it daily and leave it plugged for longer time (I left it connected for 5 minutes when testing, and then got scared and unplugged it).
Other opinions are welcome.

HTC chrger VS Samsung Charger

before i got my galaxy s i used to own the htc desire,
now when i charge the galaxy s with its own charger i never get more than 12 hours of standby and the battery just dies
with the htc desire charger i get more than one day of battery life, actually now after 1d 45min since being unpluged i still got 42% of battery life (with the exact same usage as my everyday usage)
now after checking the output voltage in both i found out that they both output 5volts , but the galaxy s is 0.7 amps, while the desire is 1amp
so do you think that i should keep using the htc desire's charger to charge the galaxy s, or this slight increase in amp can damage the phone.
by the way , i tried 2 different samsung chargers , and they both give me no more than 12 hours of standby time , so i know that i do not have a problem in the charger.
any help will be appreciated
thanks
You are tempting me to buy a htc charger as I am dying to get it past 12 hrs of usage.

I'm in the same situation as you and after charging with HTC charger I got a lot of extra battery life!!
I don't think that the increase in amps could damage the phone or battery
thx for the info i will test this to i'm getting now one day off heavy use with my sgs
report will also follow
Sent from my GT-I9000
The total amount of extra battery life was about 50% for me yesterday. Great!!
Enviado desde mi %s 2.3.3
Gonna try with my old Diamond's wall charger. 5V 1.0A. Let's see...
oooh! Is it a desire or the desire HD? might buy that charger too!
I didn't even know chargers make a difference? How is it a charger even does that?

For what phone of Desire family is it? Or all of them have the same?
If possible, please tell me the exact code name of adapter
I´ve lost my charger and need new anyway, and this looks like interesting option
Thanks in advance! .)
My Samsung Charger just stopped working and I only have my HTC HD2 charger to use so I haven't got a clue. Just shows how rubbish the Samsung one is though i barely used it as it is and its broken.
This is very peculiar to me.
The charger shouldn't be making a huge difference, but the way I see it, if the charger is output more current to the battery in a faster period of time, it might be charging the battery "more" or over charging, or the samsung undercharging.
The battery life of a phone SHOULD be determined by the mAh rating of the battery. and if both chargers are charging the phone until "100%" then they should not be draining at different rates.
The best way to test this is to get a sustained load and put it on the batteries and see if they match up to the rated mAh ratings. I wish i was still in school so i had access to this stuff so i could test it.
who cares if more amps cause damage, the only damage it will cause is to the battery.
the average battery should last the same as the phone - say 3 - 4 years ??
so if using the HTC charger ruins the battery is 2 - 3 years, who gives a **** lol, aslong as my battery life increases, im happy to buy a replacement charger in 2 - 3 years, BUT by then i would have moved on to another device anyway.
I say if it works, USE IT !!! to hell with the consequences, live life to the max !!
Thanks for sharing this info. I will give it a try with my friend's HTC charger...
Just to add to this.
USB outputs 5v +- 10% & between 500-900mA so if you charge via USB this would have the same effect would it not?
thanks alferret for that info , i really wanted to know that, so now i guess there's no harm in using the htc charger,
i am using it now as my phone charger , and i am getting no problem so far
thanks
Guys if your charger breaks the problem might be the chargers plug or mini usb (iv bought a cheap charger and it was charging but i could not use the phone literally i thought iv burned the screen)iv opened up mine and one of the wires(mine was the black one)was detached try opening with something sharp its really easy to do
just try it those cables detach really easy
Or if your really lazy buy one if you wanna
Funnily enough, yesterday at work I used a Sony Ericsson charger, just top up my phone a bit. Went from 80 to 100 percent in virtually no time.
Strange. I will check my chargers at home
Mine too , after one month and i`m using an LG charger

On Motorola and HTC phones (maybe others as well), chargers are a Micro USB cable with a USB adapter. I wish Samsung would do the same. Much more eco-friendly.
Thanks for the info. I will give it a try with my wife HTC charger.

over 25 hours to charge note 10.1 ?

Hi I just bought a used galaxy note 10.1
it did not come with a usb wall charger
after 7 hours of charging
a search said its my usb charger
I was wounding if it is normal for this to take over 24 hours from 0% battery on a charger like this
that only gives 0.5 A
or am I doing damage to my battery by leaving on charge for longer than 24 hours
its like a incredibly slow trickle charge
right now its almost full it claims but im not sure if it will ever be full at this rate
I thought maybe 24 hours but now its 1 hour past 24
I was trying to (calibrate the battery )
so I let it die to 0%
I turned the device on half way though charging
noticed it had an x though the batter so I freaked out and tryed plugging and unplugging it like 10 times
I was wounding how bad that might be for the memory of my battery to do something like that
because I unplugged it before it got to 100% when i was attempting to calibrate it
Im not sure how sensitive these batteries are
but your input would be much appreciated
You could use an off brand iPad charger with your USB cable to help it charge faster your typical phone charger will only give off 0.5 ma, so look for one for a tablet

only one thing to your problem with charging, replace the new one usb cable and your problem will be solving

I know that but I was wondering if leaving it plugged in will it be bad for my battery at all
to leave it plugged in now approaching 28 hours
the charging logo on the screen appears to have approximately 75% charge so far
I want it to get to 100%
should I unplug it if its not charged in 6-8 more hours
im mainly wondering if it is even possible to fully charge to 100%
on a old ipod usb charger or not

You are not harming your device. The only negative is that it will take longer to charge. The red is normal when not using either the correct type charging block or usb cable, it is not harming your tablet.
I would just do what some of the other posters have suggested, getting a new charger made for a tablet, just because waiting that long for it to charge is not practical.

SGN 10.1 GT-N80XX series need a specifically designed charger for them.
One thing for sure, it need to provide 2.1 A, 5 V & most phone charger only supply around 0.5 - 1 A.
Most 3rd party charger also only supply around 0.5 - 1 A.
The other is the data pin(s) & it quite different with Apple's charger.
I've tried several 3rd party chargers & Apple chargers (iPod,iPhone & iPad) & most of it unable to charge my N8000.
You need to buy an original charger for your device.
Or you can try buying 3rd Party N80XX charger on eBay from a reputable seller.
That being said, you also need an original cable to be used with the original charger.
Most 3rd party cable can only supply 0.5 A & some 3rd party charger can only be used using specific 3rd party cable.
A long 3rd party cable (10 ft / 3 m) usually can only supply around 1 A.
For example :
I have a Powerbank that uses its own cable to charge at 2.1A rate, but I can't use my own original cable with it
But my original cable is fine & I uses it to charge using my original wall charger.
It takes around 4-5 hours from 4% to 100% (with WiFi ON & all sync on)
0.5 A can't charge your device while in Power ON condition.
To charge at 0.5 A rate you have to turn OFF your device & it will take a long time to get 100%
(N80XX series have a 7000mAh battery so you can calculate how long).
NOTE:
The battery with red cross icon means that the charger/cable isn't designed for N80XX (usually the data pin settings is mismatching the original design), but it will still charge your device at a very low amperage (lower than 0.5A) to prevent damage for using inappropriate charger.

yes I will as soon as I can
thank you
I am still a little worried that It will never make it to 100% with the only one I have available for now
does not really sound like anyone has had the patience to let it go to full with this slow trickle
Amazon has the chargers and cables.
