A/C Battery Charger

http://www.amazon.com/Seidio-HTC-Th..._1_1?s=wireless&ie=UTF8&qid=1303779075&sr=1-1
Anyone use an external battery charger so you can charge your extra battery?
If so, which one do you use? I'm currently looking to buy an OEM HTC battery, but I want to charge it without putting it in my phone and charging it that way.
Thanks in advance!

I have that one and for the most part it works pretty well.
It also has a USB out so you can, in theory, charge a battery in the charger AND use the USB to charge your phone. The phone's touch screen doesn't work if you do that, however, so the USB port on it is a bit dodgy.

I've been using this for months, and had the same unit for my previous Nexus One as well. Amazing price, and works perfectly, although it took about 30 days to ship from Hong Kong.
It's great to always have 3 fully-charged batteries on deck and ready to go when I'm low on juice. Battery life is no longer a concern for me, as it takes seconds to swap them out and throw the drained one back on the charger.
Highly recommended.

Ya I've been using this too, and other than the super long shipping i'm perfectly happy with it. So convenient

Random question but do you guys know if this is the same charger as the one for the HD2? I have two stand alone HD2 battery chargers at home. I was going to pull the trigger and get this, but it looks pretty darn similar to the HD2 charger.

Its the same one. My gf has an hd2 and I can use hers with no problem.

don't charge it via A/C adapter if you want better battery life.
and how many times have you cycled the battery?

Just don't charge it at all. It's so stupid to charge your phone, nothing good comes from it! And if you need to charge, NEVER, use the A/C Adapter that came with your device like paOol said!
/Sarcasm off

Your USB cable isn't braided with 24-strand Unicorn hair. Therefore the power coming from the charger isn't pure enough for our Galaxy Nexus.

Stupid as it sounds, there is some truth to it (though OP probably didn't know, lol). Quick chargers wear out the battery a bit faster than a slow charger, so charging from the usb port on your computer is slightly better for the battery, but the charge takes a lot longer. This does not affect your battery capacity per charge, but affects how many cycles the battery lasts before it wears out.

This guy knows!
Lithium ion batteries actually like a slow charge and discharge rate . By that I mean to prolong the cells life and IRS storage capacity. Optimum rates vary a little but I found in testing that makita lithium batteries provided best service with .5C charge and discharge rates...
Not exactly the same as your phone battery, but the same chemical make-up inside the cells..
Anyway.. lol

hahahahah yes.
I heard that if you use a potato to charge your phone it doubles the battery capacity.

that seems about right to me. I browse a lot and routinely get about 3.5 hours screen time before my phone goes to the red zone. Which IIRC is around 15%?
I have my browser open and the brightness to 40% and my bluetooth off.
The battery life has been the sole black spot in owning this phone so far. I am sure the owners of the next generation phones will make all of us jealous. I bought a spare -regular- battery for just this reason.

if you want your phone to be ugly as **** and look like you have a tumor on your leg you can get this

This phone takes FOREVER to charge.

Seriously who thought it would be OK to sell a phone that takes nearly 6 hours to charge on USB and nearly 3 on the wall?
Its not even like it gets to 80% after an hour then trickles.
Rant over.

i would have said it's a small charger ...
It is a 1A charger, but Battery Widget Pro evaluates charge at 650 mA ( = 0.65 A ) for me.
Charging a 1800 mAh Li-Ion at 1.8 A will last one hour.
Charging a 1800 mAh Li-Ion at 0.6 A ( 1.8 / 3 ) will last 3 hours.
It is just as simple as this for Li-Ion and Li-Po batteries.
I can even say that your USB charge at approximately 300 mA even not knowing your specs ...
I think we can use a 2A charger without destroying the battery,
but i think HTC deliberately "lowered" the charge rate ...
Maybe someone here already tested a 2A charger and see a difference ?

Get a charger with more amps yo.
Sent from my LG-P920 using xda premium

Would you rather have it charged more quickly (like 1h or 1.5h) generating more heat and thus decreasing your battery life on phone which doesn't sport a removable battery?
I'm glad it's not that fast, the battery will last longer this way. If you don't care about that, get a "faster" charger and destroy your battery more quickly than the rest of use

Yes, i'm sure of that limitation too, but why does it charge in only 3 hours.
Looks like it is limited to 0.6A or my charger only charge at 0.6A
and doesn't have a good efficiency.
The two main possibilities are a bad battery which takes more time to charge
or a low charge rate from the charger.
While i suppose my battery is new and in good shape, it can be only due to charger or "software" limitation.
So for me the limitation is more like 600 mA and not 1A ...

Heard it all now... battery charge though put it on charge while you sleep (PROBLEM SOLVED)

Perhaps your not a heavy power user in a corporate environment who needs to charge the phone a decent amount in the airport, during the day, and so forth. HTC created a bigger problem by not allowing you to replace the battery.
Not hating, just saying, bro.

Learn about batteries before complaining about a phone you bought using a battery you don't understand. Lipo is not a Duracell and it needs to be used and charged properly.

Seems more like you have a defective charger, or at least not one rated at 1A. Try a different one?
Even with a 2A charger I have, phone does take a dreadfully long time to charge. My Galaxy Nexus with the extended battery charges to full in about 1/3 the time.

Has nothing to do with how slow the HOX charges. The iPhone, blackberry, Macbooks, hell my old T61p ThinkPad all charge faster.

Source for GOOD batteries?

I'm getting pissed with all the POS oem batteries for the S3 these days. Is going to Samsung direct my only option to get a GENUINE one? I don't see where they sell them and I don't trust eBay based on experience.

I know you can get them at Office Depot. Or you could at least, several months ago.

Sure. Brand new phone just purchased. Very few programs installed. Battery used was purchased off eBay. When indicator light showed fully charged I unplugged. Battery remaining went immediately from 100% to 88%. After 6 hours of light use, battery was already down to 40%. Within 20 minutes it fell off the cliff and phone turned off ... basically fully discharged.
Next, stock battery installed. 1 day 12 hours later battery still shows 55% remaining.

In that case I'd recommend Monster ZeroLemon 7000 MAh again.People here on XDA have really tried to suck every drop of juice out of it. It had stood all that abuse very well. Buy it from Amazon so you have solid Return Policy in case of trouble.

Thanks, I'll seriously consider it though the added thickness is a concern. If I could get 2 extra batteries close to the performance of the stock battery and at a combined price close to the ZeroLemon I would be satisfied.
How long does it typically take to charge one of those monsters?

I don't think their form factor would have issues with the SIII's casing.
I do believe they take roughly 4 hours or so with Samsung's original Charger. I don't have one myself so I have second hand information. It is true that if you have a Fast Charge Kernel, this is further reduced. I am guessing, if you charge off of a PC, of course it will practically take forever to finish :laugh:
My 1 year old stock battery goes me 3 days if on Standby all the time.It will last 1 & 1/2 to 2 days if I use conservatively.

Just fyi, fast charge kernels only make a difference when plugged into a PC and maybe a DC (car) outlet. And correct that the batteries should be the same size and ought to work fine. Only real thing to make note of is if you use any NFC features make sure the battery you get has this capability.

Bit OT here, but my regular Kernel KT747, now (in recent version) has special code for the 11th pin of the MHT port. So I am given to understand the Fast Charge thus implemented actually affects the way it charges off wall. I am testing since yesterday.

The theory behind fast charge kernels is that when you plug into a PC it detects the data connection and limits charging to 500ma or so. Fast charge kernels allow you to disable the data connection, thereby fooling it into thinking it's plugged into a normal charger and bypassing that limit.
The extra pins don't have anything to do with charging. Only 4 of them do. Before fast charge kernels were introduced people would sometimes short two of the wires in the connector (usually with solder) to accomplish the same thing.
As I understand it the 11 pins are just used with the MHL adapter for HD output. They don't have anything to do with charging. Otherwise a basic USB cable probably wouldn't even work.
I believe there are a few in depth write-ups about fast charge kernels here on xda if you want to search for more info on it.

Using the supplied charger for everyday charging?

So the stock charger that comes with the phone is a quick charger. Would using this charger every night to charge my phone kill the overall lifespan of the battery? Is it bad for the battery?

I don't think there's enough data to reliably say whether it's significantly decreasing the life, but fast charging does produce more heat which will theoretically degrade your phone quicker. I personally use a normal wall plug overnight and keep the quick charger by my desk in case I need a top-up during the day.

Pardon my cynicism but manufacturers get paid to sell phones. Slow degradation due to heat might have you buying a new one 20% sooner than if you slow charged. Not saying this is the case, but you have to look at the flip side of your argument too.

My moto x pure battery is still in good condition after using qc2.0 for a year. I'd say it's all gonna be fine.

I plan to have this phone for a long time. 3-4 years. That's why I've been a little worried about using it.

Try testing it for yourself.
I haven't used any charger except the QC 3 that came with the phone yet, but I have noticed it gets pretty warm.
Plenty apps available to monitor your battery temp. (Link in my sig )
Heat is definitely bad for batteries.
As far as charge rate it's hard to say. Fast charging a car or marine battery is significantly degrading it. Not sure about the batteries used in modern tech. I would assume they can handle fast charging well given the only charger included is a rapid charger.

Use the QC3 charger for everyday charging. It will be fine. Discharging the battery is going to hurt more.
If you want to maximize it:
discharge no lower than around 40-50% or so.
charge it higher than 90%.
Have fun using your device.
