Trying to reduce clutter and use less outlets on my desk at home, I have a GT 10.1 and the E4GT and was wondering if it was safe to use the brick from the 10.1 with my micro usb charging cable for the E4GT.
I know they have different amps, the GT is rated higher, so it should charge the E4GT faster. Just not sure if this is safe.
I know for Blackberry's you can buy the rapid playbook charger and use it on the phones for a faster charge. Now that I think about it, I have used that Playbook quick charger with my E4GT. It works fine but I just hope I am not damaging my battery.
Thanks

Well, you can charge it faster but i will over time reduce the battery life. coming from an electrical back round, The best thing for the battery is bring it up on a slow charge. Lessens the chance of burning/shorting out a cell. L-Ion batteries are great for not having a memory like Ni-Cad or Ni-MH. So i frequently throw my phone on the stock charger a few times thru out the day. I would recommend you stick with your stock charger as it was ment for that battery. hope this helps.

Thanks, I did not realize that a fast charge can harm the lithium batteries. On a side note, lithium batteries can only be charged a certain amount of times correct? So if you charge your battery say four times a day, you have used up four charge times/cycles?
Thanks
A sprint tech told me that our phones have a built-in safety, and will not engage in charging the battery or damage it in any way if the amperage is incompatible on the charger.
Beware: this information came from a sprint rep over the phone, and I wouldn't even begin to know how to verify it.
Yes they are limited to certain amount of times they can be charged. I'd have to look it up again why tho.

No need to look up the reason, just wanted to make sure that I was correct in thinking that. I try to charge my phone only once per day and at night, if I have to charge it up during the day I will but I try not to keep pulling it on and off of the charger.
Thanks
OK. Yeah there are a lot of tweaks out there. Like if u use voltage control, use agat or sleshepic's TW ICS kernels and under volt and use conservative govener. Really helps battery life. Also depends how you use it

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.

ok so my wife had a sprint incognito (sp?)
anyway.. since she now has an iphone... i took her car charger... while my at&t car dock is on its way...
well i ran TeleNav and Winamp on the way to work.. that was it...
and i started off with a full battery and ended up at 89% at work.... 1hr drive.. 60 miles...
so while that would yield almost 10hrs of gps/music.... phone must be charging.. (you can see the battery charge icon fill)...
so this isnt running much on this phone.. shouldnt a car charger keep up or is it that this one was meant for her phone with less power requirements so it didnt charge as fast???
Your phone is consuming more power than the charger is pushing, its a common thing under heavy use, especially if your using nav and other apps running.
thanks.. yeah i figured it was consuming more than it can charge.. so i wasnt sure if maybe the recharge rate for the older phones dont charge as much... or if no... all chargers are created equally but phone use is the difference...
All chargers are not equal most are 5volts 1amp some are alot more some alot less and some put the phone in USB mode that limits the charge

I upgraded to Jelly Bean the day before yesterday. But upgrading I've found that my charging time gone up quiet a bit. Its taking almost 30-40% more time to charge than it used to do earlier on ICS (stock). I'm running stock Jelly Bean on my Gnex. Is someone else also having this issue?
For me, approximatively 2-3 hours for full charging.
I think its more faster than ICS
I think I'll try different chargers to check the issue..

Hm... I'm no expert at this, but maybe JB slowed down the charging amount so GNex doesn't get hot when charging. I found my GNex to charge a bit longer after the update too. But now when I'm using my GNex, it doesn't get as hot as 4.0.x
Takes a couple hours. But completely dependent on the charger and cable. Long cables have more line-loss, and chargers vary from 500mA to 2.1A in output.

LOL what? Longer cables in NO WAY effect charging time.
LOL... that's a good one. Also, the Galaxy Nexus charger is rated at 1 amp. You should not use a charger OVER 1 amp or you will damage the phone's charging circuit.
And I used to thought the higher Amperage doesn't affect the battery at all. Even if the 'amp' is high,the device will pull only that much of 'amp' that it needs. Rather we should ensure that voltage should not be higher than the rated one for the device.

A longer and/or thinner cable does have more resistance and so loses a bit of its power (V*A) over the run as waste heat. If it is already at capacity, that loss would slow charging a little bit compared to a shorter cable. If not, then its just wasted energy for heating the cable.
To your second point, any 5volt charger capable of delivering over 1 amp at 5V ( clean DC ) will safely charge a GNexus. Any unnecessary amperage capacity will just not be used. Charger will run cooler.
You could use a 6V auto battery charger with LOTS of amp capacity if it were 5V instead of 6V, and if it were clean DC, but it is not.

And quite a bit more expensive. The only real difference I see is the charge rate. IIRC I read somewhere the Mophie covered the power button and I use the IR blaster. Either way ill give this one a shot, if I dont like it ill check out the Mophie.
The output of 500mA convince me not to be a guinea pig for this case.
I'm convinced that's just not enough power to charge up the phone while in use. Also that rate of output I'm sure it will take hours to change a phone.

I dont need it to charge. I just need it to sustain power. If both the phone and case are full just turn the case on so it discharges first. Its perfect for me, itll keep my phone topped up while im at work and not using it much.

The phone should stay charged if you don't use it much even without the case. I'm not sure what's the purpose of having a case if you're not using the phone, it will stay charge while not in use.
I personally need the case to be able to charge my phone up or hold charge while it's propped up streaming a baseball game with the AtBat app.
But I know for a fact 500mA just won't be enough power for the phone to hold a charge while in use. You will actually get power drain while in use.
Either way guys let me know how it goes I'll keep an eye on this case.

No offense, but what's your problem with this? Batteries drain when in use, period. If you're using a battery case, then the batteries are still draining. If I wanted to actually charge my phone, I'd use an external backup battery or AC-- I'm ordering this case to extend runtime by slowing consumption rate.
It just seems like you'd be better suited with an external battery.

I don't think you used the mophie juice pack before because it actually charges up the phone while you using it. That's a feature I actually need because I will actually watch a baseball game or two while at work and don't want to be tied down to a power cord.
With the Mophie case I get 2 full charges and what ever time it took the case to fully charge the phone. Needless to say I'm cordless for a whole day with heavy heavy usage and constant screen on time.
I want this case for the simple fact it has a kickstand but besides that what's the point in having this case if all it does is charge the phone while not in use. And it does a poor job at that too because it takes up to six hours to get the battery fully charged if you don't use the phone.
Does this case actually extend usage by slowing consumption rate? By how much is the question. I don't think much with the .500mA out put.

Different users, different use-cases. "Not in use" means different things to different people, and my phone consumption is tweaked to be pretty low. As is I usually get through the day with about 30-50% left at the end; while I'm walking around at work, it's just playing music or I'm using a tablet to watch video instead (since I don't want to use my work machine for that...you can guess why ). Since my phone cycles down a lot of the time, 500mA is enough to trickle charge when I need it, and slow usage (by the USB charge rate, which is hardly shabby) when I am.
Since I don't need to use my battery aggressively, there is certainly a point for my use-case. And I really can never see a situation where I would want to charge my phone completely. If I really had to, I have external batteries for tha.t
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.
