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 ?

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.
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.
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

Hi, I was hoping you guys could shed some light on my charging issue.
I am having the following issue, either it takes forever to charge like 1% an hour or when the phone actaully does reach 100% and I unplug it, it then drops to 80% right away.
I have tried different chargers, outlets and batteries as well as a factory reset. Nothing works. I tried charging my battery in another GS2 and it charges fine. I have no idea what could be wrong.
Try Wiping your battery stats.
How. I am not rooted.
Also, by doing a factory reset, didnt that wipe the battery stats?

Are you using the stock charger? Do you have and radio or antennas on, sync on....
Only thing I can think of is a battery drain problem such as an app on auto sync like Facebook. Turn off all app sync, phone sync, and radios. If that doesn't fix it.....then it's a defective device.....but I suspect a app draining the battery. btw...how long does your battery last?

According to an article or thread I read here on XDA ( I can't remember I'll try and find it ) our phone recognize the chargers you plug into it. It recognizes Samsung chargers and charges optimally but use any other charger and it will only charge at 500mah even if the charger is rated at 700mah or even 1a. Makes sense because I have 3 chargers. 2 Samsung wall chargers rated at 700mah and an HTC charger rated @1a and the Sammy chargers work much faster. I'll test how long it takes to get from 0% to 100% charge with the Sammy charger then use the HTC one on the next cycle.

Apparently, our phones don't get along well with certain 3rd party chargers, and if you use one, it'll wakelock your phone until you reboot. For those of you who don't know what a wakelock is, the short version is it prevents your phone from deep sleeping, screwing your battery life.
I'd been using an old Blackberry charger with my phone, and using the linked app, tested it and discovered it was causing this problem. After switching to a different charger, I get much better battery life now.
I highly recommend anyone not using the original charger to test their charger and make sure it's not ruining your battery life.

The phone can detect when you're using ANY charger but the original Sammy charger. There are 2 switched pins on the charger that detect this. When the phone detects an incompatible charger it only chargers at 350mah. When using the normal charger it charges at a full 700mah or whatever the charger pushes to the phone.

Sorry, but that's a flat out fib. This subject has already been fully established and spoken about. Look it up. Even TheDerekJay himself has spoken and elaborated on this with his development findings on this phone.
I also have numerous chargers. 2 700mah Sammy chargers, an HTC my touch 4g charger, iPhone 1000mah charger, and Evo 3d charger.. safe to say none of them charge nearly as fast as the Sammy chargers. Approximately 3 hours from 0% to a full charge. Around 5-6 hours with the others.
