Source for spare battery

Yesterday I used my JJ in the way I use my Treo 650, as a mixed PDA and cell/mobile phone. Now my Treo battery gives me 2/3 days of use (it is on 24 hrs a day) while my JJ after about 15 hours was down to 25% battery capacity (and I did not use WiFi but used BT for 10 hours, about 2 hours of ebook reading and the usual PIM/sync activities and about 20 minutes of calls). With this sort of battery usage I really need a spare battery (I do have a portable USB based batery charger that I could use as a fallback).
Where can I get a spare battery from? Expansys claim they will have some around 2nd week in December!
Thanks

To Jah,
Mugen Power will launch the latest extended battery for the JJ. Pls keep on watching this forum for further information.

Any realistic idea when? I can hold off for a short while...
p.s. awful web page, seriously - Contents of http://www.unifirm.com/pda.htm means nothing to a normal user.
Use the device names and capacities - "XDA Exec, 1750MAh" sounds a lot better than "HLI-X3SL"...
EDIT: And I can't even click on the things? Useless.

Please make it a higher capacity one, double or triple the current capacity would be nice.
A charger to come with it is also appreciated. I'll grab it as soon as it comes out.

A battery charger is definitly a must have, The xda takes too long to charge because of it's mini usb connector, even when connected to an AC socket. I wouldn't bother buying a spare battery cos with the current charging options It will just take too long to charge the batteries up.
Besides, one can only charge a battery at a time since there isn't a dock with a spare battery charger or a standalone battery charger for the htc universal.
A fast charger for the battery alone would be excellent.
Got mugen batteries for all the pocket pcs I've ever owned and they rock.
Hope to get some feedback from mugen on developing a fast charger, I recon alot of htc universal users will be very interested

In this case HP teach!!!!
Before JJ I had a HP6515. I've bought spare high capacity battery and I've received it with it's separate charger who connects to the main cradke with a bypass. FANTASTIC!!!

Electrical question - charging - power

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! I posted it also in the general section, but since it is an TP2 issue maybe it is better placed here.
Sorry for possible inconvenience!
THX!
Kjoere

Each USB port churns out 5V at 500mA max (i.e., 0.5A).

Thank you mesquire,
Do you have any idea what the effect is of charging with different AMpere?
E.g. my BT-earphone has 180mA - so better not charge this through laptop I suppose (too much is never a good thing) - but the otherway charging with less A, that I haven' got a clue ...
C.

You can face problems that it starts to charge, but stops after x minutes.
I have replaced my carcharger with the original HTC CC C100 which delivers 1Amp.
Never had any charging problems with that one.

Hi ronh,
replacing is ofcourse an option, but I was mainly wondering what the possible effects could be on the battery. On a Dutch site I found that Lithium-Ion batteries have no memory effect so all ampères below should be "theoretically" be ok.

You can expect longer charge times through USB port than with the supplied charger.
A USB flash drive draws only about 100mA from the port, so the port should provide just enough power to charge your Bluetooth handsfree (but do make sure the device needs 5V to operate or you could fry it).

Hi mesquire,
thanx again, but I am still in the dark. You seem to make a difference between a USB port (500mA) and a USB flash drive (100mA), but i don't understand this (maybe my english isn't good enough ).
Do i understand you correctly is i say that the device connected also has sth to say in how much power comes out?
I thought the ampere is sth like a 'flow of current' and when more comes out than wanted by the receiver, it euh likes ... flood (too much current) the device (and does damage). Does this make any sense?
Ciao,
Kjoere

Your device will only pull the amount of amps required,
as long as the input voltage is the same you should be fine.
you will be OK to charge the phone at 500ma however this will take longer to charge,
I charge mine using my laptop regularly - that matches your car charger at 500ma,
you may find however, when using gps etc, that you are draining more power than being supplied by the charger and the battery will begin to discharge.
hope this makes sense,
Steve

they do have a memory, but the software/charger will not let you damage the battery.
anyway, assuming the battery can be charged at 1C (up to 2C is possible with some batteries, but can adversely affect battery life) you can theoretically charge the battery at a maximum of 1.5 amps safely. (assuming 1,500Mah battery)

TP2 doesn't have li-ion, it's a LiPo which doesn't have memory. They do have a limit on how many times they recharge as well as a shelf life, figure on buying a replacement every 1-2 years I'd guess.

are you sure ?? i went to the power settings and it says main battery: Li-ion
which i presume stands for lithium ion ?

Lithium Ion doesn't have memory.
Nickel Cadmium and Nickel MetalHydride have meory: i.e. if you charge it when it's at 70%, the next time it gets down to 70% it will think it's empty as it "remembers" that as the charging point.
With Lithium Ion you can charge them at any moment, ergo no charge. Adn they too have a life of about 500 charges.

The battery in my TP2 says LI-ION on the back, so perhaps some are LI-Po and some LI-ion? may go some way to explaining why some people are happy with their battery life and some not so.

Shouldn't really matter truth be told. As long as they have a rating of 1500mah they should last the same amount.

my australian TP2 says Li-ion in big letters, and Li-ion Polymer in the fine print

The difference is in cost, and weight, but the end result in a cell phone or pda is more or less the same due to the low power demands.

My TP2 battery says Li-ion on the actual label itself.

thanx

Hi Steve,
Thx man! So now i Know i only have to worry about voltage. So I can charge my earphone in my car (which only wants 180mA) and my phone (1A). You are right that it sometimes (navigation, BT) uses more power than it gets (500mA), I get some message saying that by the way.
Any way thanx a lot !

[Q] Use E4GT straight from power source without the battery

Does anyone know how to achieve this? I would suspect shorting the 3 leads (or a combination) in the battery compartment without the battery inserted and while plugged into a usb AC adapter would do the trick. However, I don't know the exact electrical layout of those leads....
Great for long road trips (gps + dashcam usage) or tethering so as not the wear out the battery prematurely.

Sounds like a bad idea.

Take the battery out and plug the phone in.
Sent from my SPH-D710 using Tapatalk

If one can jumper the connections to mimic a full battery...then it should be able to run off a power source such as a wall socket AC adapter or usb car adapter. Of course, the resistance of the battery should be taken into consideration when doing so. I just need the pin outs for those leads....
The battery temperature gets way hot...into the high 40s C when tethering, which is definitely not conducive to prolonged battery life.

Well..as i said before. The two main reasons for this is while Tethering and when using it as a Dash Cam + GPS while driving. The phone gets incredibly hot along with the battery temperature. Eliminating the battery will relieve the extra temperature as well as preserve battery health.

I just took a 9 hour road trip and used sprint hot spot for tethering a handful of devices in the vehicle. What I did was take the back off the phone, let it sit over the windshield vent and had cool air blow into it. It stayed nice and cool. I used an unactivated phone for Google nav using wifi.
Tethering maxes out the processor for a long period of time, that's why it always gets hot.

Thanks! That's a great idea. Oh wow...wifi hotspot eats up the battery like no other, which brings me to my next question.
What USB Car Adapter did you use with it? I've read that typical 1Amp usb car adapters are unable to charge or even maintain battery level when cellphone is running with all radios enabled due to the large amount of power draw. I'm looking at a small and very discreet 2Amp usb car adapter, which should be able to provide enough juice for the phone running with all radios on.
Some considerations I've been looking at:
http://www.amazon.com/Miccus-Charge...1?s=electronics&ie=UTF8&qid=1329682002&sr=1-1

http://www.amazon.com/Kensington-K3...?s=electronics&ie=UTF8&qid=1329681948&sr=1-10

If you look on the battery you will see which pins are positive and negative but i seriously do not recommend doing that. It would probably work but it would be very risky if those power leads touch "short out" your phone is dead, you never "short out" electrical connections especially on a phone! unless you want to short out your phone (very bad!)
I think the best thing you can do is get an extended battery so you can tether without having to charge at the same time, and that way the battery shouldnt heat up that much, as well as last alot longer. However if your gonna go 9 hours then you should definitely stick it in a A/C vent or something!

I had a power converter and used the outlet charger and USB that came with the phone. Yes the phone did loose power while on the charger, but didn't go dead.
Anything that's 1A 5 watts is the maximum the phone will accept. I wouldn't advise going over 1 amp.
I used the Griffin charger before. I don't think it kicks out the power as advertised. My phones always charged very slowly with that charger.

External Batteries

I was just wondering whether external batteries are generally quite reliable, and if so what the best brands are to go for? I am looking for a relatively powerful one - I am not afraid of a little bit of cost, but obviously I don't want to spend masses.
Thanks

Ive got a New Trent and its well built and reliable. The 11000mAH will last you for several days. Have a look on Amazon.

I have a "Just Mobile Pro" or something like that.
4400mAh with 1000mA output.
But the EasyAcc 5600mAh (which I don't have) does sound better and cheaper (on Amazon).

Second new trents 11000mah one that thing is a beast

Hah! Good thing I didn't have a mouthful of soda there...

Good thing to remember with external battery packs is that during usage some of the charge goes to charging the battery while some is lost in heat. I think I read some where its normaly 30-40%. So for example a 11000mah battery will give you some where near 6600mah of charge so about 3 and half charges of the HTC One X.
I'm considering either the:

The heat loss is inevitable but the capacity should be unchanged.
What the heat loss means is that you need more than 11000mAh to charge up the full 11000mAh battery due to the losses.
The tecknet is very good value. I am considering it at the moment

Yes but I'm talking about in the other direction. So once you have 11000mAh in the device and you charge a device that take 1800mAh you will actually use aprox 2520mAh in doing so. My numbers and calculations maybe a little flawed but my point is that you cant do a simple 11000 / 1800 = 6.1 charges as you need to take into account heat loss which is around 30 - 40% (so I read on one of the amazon reviews)
Either way both devices are nice and cost quite reasonable.

Not sure how efficient but if say 10% loss, we still get around 5 times charge with a 11000mAh batt. to a One X.

Also don't forgot not to simply divide the battery pack's capacity by your phone's battery capacity to see how many times it will charge, unless you are charging it with the phone turned off.
With the phone on it is obviously using the usual amount for running the phone, whilst it is being charged. Add the current being drawn for keeping the phone running (say 250mA when awake) for the time it takes to charge (for me 2 hours) and you are looking at 500mAH. Add that to the capacity of your phone battery before dividing it by the capacity of your battery pack to figure out how many charges you'll get from it. Figures used are just for example purposes. Use a current widget if you want to know how much your phone is using.
Plus like a phone's battery, a new battery pack will take several charge cycles to reach full performance. Where as with a phone's battery which only takes about 2 weeks (charging it every day), a battery pack will take that much longer to get the full performance out of, as you wont likely be charging it more than once a week/month.
And then there's the battery indicators. These New Trent ones look sensible, but I once purchased a Proporta Turbocharger 5000mAHr unit. It had three blue LED battery status lights that were always on if charging. If you looked directly at them they'd burn your retinas out your skull. They could be seen from space. Stupidly and comically bright. They HAD to eat into some of the capacity.
Copper losses over the cable at the distances involved in your average charging cable will be negligible. If you really want to reduce it, don't use those silly skinny retracting yo-yo charging cable things that some of them come with. Use a decent quality USB to microUSB cable. The higher the guage of the cable and quality of copper, the less volt-drop there is. I keep a good few of these kicking about at home as they are well made but not too costly, and come with a nice cable tidy clasp...http://www.ebay.co.uk/itm/GENUINE-NOKIA-CA-101-CA101-USB-DATA-CABLE-LEAD-5230-/140579882085?pt=UK_MobilePhones_MobilePhoneAccesories_MobilePhoneDataCables_JN&hash=item20bb36c465

Got 2 new batteries and I want to keep them for a while, so I have a few questions:
1. Is the OEM fast-charge charger and cable okay to use every day, or will it degrade the battery faster than a slower/regular speed charger/cable?
2. Since I have 2 batteries now, which is the best way to charge them both up? charge 1 in the phone, then swap and charge the other in the phone? Or buy a battery charger (and if so, which one)?
3. Any other helps regarding the chargers and/or cables?​Thank you for your help.

Faster charging will always generate more heat and put more stress on the battery, so slower charging would be better for a battery's lifespan, but I don't think you'll see a huge difference within two years.
By far the fastest way to keep going is having the second battery charged in an external battery charger and then swap when the other battery gets low, followed by charging the low battery in the external charger. Doing it this way also puts the least wear-and-tear on the phone's charging port since you'll rarely use it. I use LG's OEM external battery charging cradle (BCK-5200), but it may be hard to find nowadays. There's currently a used one up for sale in an auction by an American seller on eBay, and there are new ones from a South Korean seller for a higher fixed price. I wouldn't pay more than $25 for one. As for charging time, for me, it takes about 4 hours to charge my MaxxxJuice 4100 mAh batteries from ~5–10% to full. External chargers do not fast-charge, so you'll never put too much stress on the battery that way. Of course, swapping may not be for everyone as it may be inconvenient to take a case off and put it back on.
Unlike the older microUSB cables, bad USB Type-C cables that are not built to certain specifications can draw higher currents and destroy the devices they are charging. A few years ago, a Google engineer reviewed lots of USB-C cables on Amazon to give his view on those. If you need a third-party cable, make sure you get one from a reputable source with good reviews. My preferred USB cable is Anker's Powerline+ due to their extra strength/thickness, and I don't need much flexibility/twistability in my cables. Also, I like how the USB-C end connector is made of one single piece where you don't see any connecting lines around the middle (you can see an example here).
Other thoughts:
As long as there is a supply of extra batteries around and you can afford to buy them when the time comes, then you shouldn't worry much about how you charge your phone. In my opinion, that is one of the main selling points of having a hand-removable battery. I imagine a paranoid person on a phone with a sealed battery would be trying to keep the battery level between 40 and 80% at all times. So really, the only thing to worry about is having a decent USB-C cable and making sure the phone's charging port is clean and not worn out.
In case you are really interested on my detailed charging habits and related things on my V20, I discussed them while reviewing my batteries a while back on the V20 Subreddit.

Thanks!

On that Subreddit, you mentioned you cycled a couple batteries. Did you have to do the whole fully charge and fully drain thing each time you switched to the new battery, or just when you first bought the batteries?

Would like to know the answer to ^this^ as well.

No, I only did the full cycle with the first battery three times, and that was it. The only reason to do that is for the Android software of the phone to get a better sense of your battery level. Of course, it won't be as accurate the longer you go swapping between batteries as undoubtedly they will differ a bit in capacity over time. But fully running down and then fully charging a battery isn't good for its lifespan if you do it too often. The only other times you'd have to really repeat the calibration is when switching to a battery with a different capacity or switching ROMs / doing a factory reset.

So, I got a 4000 Powerbear that I'm calibrating now.
I'm also getting a 4100 Perfine.
Are they close enough that I shouldn't have to recalibrate for the 4100?

Most likely yes. I imagine most of these 4000–4300 mAh Lithium polymer batteries that started popping up this year are very similar, and some may just be rebranded from the same common factory source. Barring a defective battery, if the two batteries had a significant difference in capacity, you could see things like early shutdowns on the smaller capacity one or being stuck at a low percentage for an unusually long amount of time on the larger capacity one.

Great info.
So it looks like all other batteries on hand should not be put into rotation with the higher capacity batteries to avoid inaccurate readings in Android.

Pretty much this. I suppose one could try keeping separate copies of the batterystats.bin file from /data/system when rooted and swap them alongside the different batteries. But that sounds like too much of a pain to deal with, even if it works.

Just to add to this, I found your pics @C D for the charging instructions and there's a note about using 3200mah batteries along with the 4100mah batteries.

Does that mean that if you switch between the batteries, they'll both last as long as they should (the 4100 longer time than the orig. 3200), but the system's percent will be wrong?

My understanding is that if you calibrate the phone to recognize the full 4100mah and then use a 3200mah battery, it will shut down early (but still use the full 3200mah).

Correct. They are warning you that swapping between batteries of significantly different capacities will throw off the accuracy of the phone's battery percentage indicator at all times, especially at the high and low percent values (so an early shutdown can happen when the smaller capacity battery is used). Of course, this won't affect either battery's true capacity.
I'd pay good money for a system that can correctly handle different battery capacities of any amount, but we all know where the future of hand-removable batteries has been heading for the last 3–4 years.

Does anyone charge their phone ONLY to 80 % or so?
If so, what apps do you use to limit this? Any other tips/advice?

I use AccuBattery and it has a notification sound that plays when you hit the target charge percentage, but it's still up to you to remove the phone from the charger or else it continues charging to 100%.
Since our phones have replaceable batteries, I haven't made any special effort to take care of them. I have a pair of May '17 OEM 3200 mAh batteries that are going to get switched out for a pair of new 4100+ mAh Li-Po batteries once I get my second V20 set up. Every charger I use is QuickCharge 3.0 certified except for USB on my PCs and my Pioneer Android Auto headunit USB connection in one car. The vast majority of the time, I charge via QC 3.0. Pretty much the only time I let the battery charge via PC USB is when I actually need to transfer files between the phone and computer.
Before my phone started having issues in the past month with a phantom power drain, I would let the phone charge from 30-40% to 80-90% and then remove it from the charger at night before going to sleep. In the last half year as the batteries have aged, I've let it get up to between 90-95% before unplugging. For the past month, I've been charging the phone four times a day from 40-100% to combat the power drain issue, but that comes with knowing that I don't care about these old batteries or the state of the firmware on this first V20 anymore.
As for when I swapped the two batteries I have, that entirely depended on when I actually ran one down so far that I needed a 0-100% battery swap, which could be months at a time and usually happened while on vacation or away from a charging source for a longer period of time than what my usual home/car/work routine allows.
