Guaging Interest - better battery charger?

I've got a contact with the owner of a company who builds custom battery chargers, currently they develop chargers for marine applications (on-board ships, subs, ect.)
if we R&Ded a charger for our phones.... perhaps even built it into a cradle... would anyone be interested?

Who's paying for the R&D and what is the MOQ?

it's my father's company. thought started out as mainly designing a better charger for myself... but depending on the results & interest, we might produce a few more.
company name is Quality Marine (www.qualitymarinechargers.com)
current model we're looking at is the HD2 (since that's the phone I got) but again... depending on results & interest, we might expand to other models.
first thing we would need to do is see the condition of the battery after a standard charge... see the limits of the battery, and a few other factors. Potentials would be better battery life (not how long a charge lasts... but lifetime of the battery) faster charge times, and potentially other factors... (as we haven't done any testing with the battery yet it's hard to say)
anyways... that's where we are at currently

Charger
I would definitely be interested.

Check out the one at Obostore... Cradle plus extra battery charger in one. I picked one up and it's great.

Already have it.... if you look, the output voltage on the charger is different then the stock HD2 charger (it's lower)
it's possible with the internal circuitry it could be a "trickle charger".... but I doubt it.
Also... i'm not so sure I like how the phone sits in the cradle... it feels to put the majority of the weight on the microUSB port and not on the cradle.
it's an ok cradle for the price ($20 if I recall?) but I think it could be done better.

I agree... It could be better for sure... I wish it was angled so that the phone would rest on the back of the phone and so it's not sitting straight up... The question is, is it even worth it since this is a WinMO6.5 phone? Tmobile could stock selling HD2's when the Winmo7 phones start coming in.

don't know about you... but I'm not going to drop my HD2 for something else for at least 2 years, when I'm due for an upgrade again.... Don't really feel like paying for the same phone again
And... if I've learned anything regarding MS products, you should always wait till after the first SP before you use their new stuff haha

True. I'm just thinking about this dude throwing down a TON of cash to make the MOQ on something like this and being stuck with them because the demand isn't huge... Seems risky from a $$$ standpoint.

TBH, I don't think the MOQ will really be that high.... we're only talking about a 3.7V battery after all
the concept & design will be mine... as the project will still start with making something better for my phone and as I said... depending on how it turns out, we could make more depending on results & interest.

The stock USB charger for the HD2 is already very good. I use it to charge all of my USB devices from Garmin GPS to HD2 and other things

Did you ever make that better charger?

3 batteries for $ 10 ??

is that these batteries are genuine ? reliable? 3 batteries for $ 10 is cheap? here in Brazil a battery that is on average only $ 25 .....
worth buying?
thank you
http://www.ebay.com/itm/3x1200mAh-b...ccessories&hash=item3cbb1dedb9#ht_2052wt_1034

or this is too good
http://www.ebay.com/itm/High-2200mA...976869?pt=PDA_Accessories&hash=item19c8ea3de5
but not 3.7 voltage..i dont know,better voltage for cpu? xD

That battery is a huge hoax and has been posted long ago.
For the first... The batterys looks original but i can doubt that they are really. The chinese batterys are good. Some even better then japanese or european batterys, but there is low end.
I think these are aftermarket non-genuine but could be good batterys, maybe worth the price maybe not... it's your choice.

dude that is a battery charger.. not a battery

[SOLVED] OFFICIAL & UNOFFICIAL batteries don't charge and question mark

Hi all,
First of all, sorry if someone talks about it earlier, I red about 10 pages in Development & this topic and found just NOTHING about it, or no solution.
I bought two batteries for my Milestone, a genuine and a compatible. Both aren't working. My phone power on with them in (sorry I think this isn't English lol) but it can't charge them (no LED, and no effective battery charging !). What's more, I have question mark in the battery icon !
I tried almost everything including trying EACH famous ROM (batteries is just working with a MIUI-based on ROM and I hate this one a lot (very slow) and I'm an iOS-like hater) and (except MIUI) it doesn't work !
Even with CM(6&7&9), the FroyoMod 2.9.3, HO!NO!Mod7.2.0RC0 ! What's the problem ?
If you have any proposal or solution, do not hesitate to tell me !
Thank you all !

Sounds to me like your USB port may have bit the dust...If you have to keep the phone, I'd say buy an external charger off of ebay, they're pretty cheap. For 15 USD you can probably get a charger + 2 generic batteries, which isn't too bad!

Sorry but you're wrong. I said (and this is a fact) that i can charge my genuine battery with MIUI. So no problem with USB.
Moreover, I still have my first battery fully working and charging with ANY ROM and have no question mark ! But that, you can't imagine it sorry :/
(I don't really control the English therefore you should not be vexed by my answer)
But thank you very much for your proposal. I try to explain better :
Note that I still have the first battery and it is fully working (charging with anything but have some draining issue)
I bought two batteries, one genuine and one compatible. Unhappily the compatible one die (I left it in my phone till empty..).
The fact is, except on MIUI ROM, I CAN'T charge the battery and the battery icon is... a question mark. Had someone the same issue and solved it ? If yes, please give me the trick. If not, you're guys like me, you can propose all of your ideas obviously.
Sorry for bad English

The genuine battery (the one you bought recently) won't charge? By genuine you mean original motorola? But the original one that came with phone is working properly? And the battery you bought recently, the one that is not original motorola, died because it drained it iself and now does not charge anymore?

OK. The (sold as by a famous french shop (FNAC)) genuine battery which I bought recently won't charge except on MIUI and always show a question mark (except on MIUI obviously). Sold as an official Motorola battery, that's genuine for me.
Yes the original one coming with the phone is working properly And the compatible one bought recently isn't an original (not sold as but looks pretty much the same as an original) and died because it drained it iself (because used in the phone) and now does not charge anymore.
Sorry if there are misunderstandings :/ (because of my misformulated English)!

I belive it is safe to assume that those new batteries are defective. You have one (phone's original) that is working flawlessly while new ones fail.

It is because of the implementation of one percent battery steps. if you are using cm , try disabling them. It is working fine with miui because it does have it implemented

I disagree. It works on MIUI, so they aren't defective It was obviously relevant to the ROM and no to the battery !

WTF !? You're wright for the genuine one ! I will try with the compatible one later. Thank you so much !!
EDIT : It works with the compatible one, thank you again ! Now, I've three batteries... Too much ^^

[Q] whah about charging the one with ..

is it good idea to charge my htc one with an samsung 2A charger rather than the 1A ? iss harmful for the battery ? whats the cons and pros

Should be fine; the phone won't take more than 1A. It might only take 0.5A if the data pins aren't shorted.

try searching (sorry not kidding), but there is a thread here in Q&A with similar question, and some very experienced electrical engineer & phone repair dude gave a very long description.
if i remember correctly, the phone won't use anything more than it needs, so going over 1A is OK, the phone will only use the 1A
on the other hand using lower level charges, will over the long term damage the battery.
i'm no expert in this, go searching for it, it was a quite interesting post. (sorry, i didnt bookmark it, if i happen to bump into it, i'll let you know)

Yup you are correct. I know i have answered it a few times in other posts. heck maybe im the phone repair dude your speaking of.. Or not.. LOL
Basically the phones Kernel will not allow the unit to over charge. There is hardware (that talks to the software) that limits the maximum amount of input current. That has been set by HTC at around 1A. So if you hook up a 2A charger your fine as the device will only draw 1A max.
I my self ran across many blackberry playbook tablet chargers dirt cheap and have them at work and home. They work great for charging everything from tiny Bluetooth devices to full blown tablets.
HTC sold us devices with a non removable battery. So they decided to not allow us to charge it to fast to reduce the heat and maximize battery life.
Remember the two most damaging thing to Li-Ion is heat and extreme low voltage.

[Q] HTC Warrenty

Hi guys, I bought htc one, almost 6 month ago. It was amazing nd all but i still felt it wasnt working well.
Then i used some roms .. didnt help much. battery was killed. I thought it was coz of rom. Well then finally after asking alot of advice here, I returned htc one to 100% factory settings (pain in the a..) then sent it to warrenty.
Here is a list of all things they changed (attachment). Is that normal?
did i have a really badly made htc one? or did i broke the components by using unoffical chargers/roms/kernels etc etc etc.????
Since I have noticed that it works WAY faster and battery is way better than it was.
maybe its coz i used xcover 2 the time htc one was away so i kinda got used to that piece of s... ? anyhow im way more satesfied with it now than before. but still, this is first time i sent phone to warrenty so i dont know if this much changes to the device is normal or not
Ps. The reason for giving it to warrenty: battery would get to 100%, when unpluged worked normal until 60-70%, then it would just die. no way to turn it on without puting it on charger atleast for 20 minutes.
(if i didnt put it on charger.. after 2-3 hours it would magiclly get 20-40% charge lol)
sorry about my english guys

Wow they changed a lot of things here!
I see 2 options, either your battery over heated and died + damaged some components or they damaged the phone when trying to open it to change the faulty battery/usb port.
Don't worry, at least your phone is working good now, there is so much horror stories about warranty repair here, glad to see yours came back in good condition.

Thanks for the reply bro.
Now i wanna know what caused the death of the battery. was it coz i used some unoffical chargers?
(like samsung charger which is for note 10.1 tablet, and some nokia chargers)
or was it coz i flashed roms way too frequently?
I m scared to unlock it again and start flashing but i really want to

You should only use official chargers, or at least be sure they output the same voltage (5v). There are some tablets charger (i.e Asus TF101) that output 10V and that amount of voltage will probably kill the battery....
Maybe it was only a bad battery, maybe damaged by CPU overheat.... who knows
Flashing roms doesn't damage the battery

Ok, so the culprit was the tablet charger.
Well its good to know about the roms then finally can get back to CM11 until offical sense 6
