Charging time

How long does your Desire take to charge? Mine takes ages, gone up 40% in 2 hours, which is exactly the same as the discharge rate when I'm using it. I'm sure my Blackstone used to top up much quicker than that. More and more I think power management is screwy in this device.

Are you using the original charger and cable?
I used a different cable with the original cable a few days ago and after about 6 hours it had only partially charged. Using the original cable it does a complete charge in about 3 hours.

if u use usb charging, it takes very long, but should be done in around 5 hours as well. if its ac adapter, much quicker, about 2 ~ 3 hours.

AC-Adapter:
15% to 100% (15% = "Warning") : ~90mins
0% to 100%: ~2hrs
With USB I think you can (at least) double that time.

Mine currently has been on charge for over 3 hours from about 9% and this is via AC with the phone turned off. I should note that it is via AC through an ipod/iphone charger which is rated at 5v @ 1A so I guess I'm just a little concerned if the ipod/iphone charger is maybe charging it at 500mA instead of 1A.
I know it's not faulty as it charges my ipod touch much faster than pc USB, but I'm just wondering if the cable supplied on my desire is forcing it to charge at 500mA, thinking the ipod charger is just a pc usb thingy.
I'll look into getting a travel adaptor or a brandless micro usb charger off ebay soon but it just seems odd to not charge in the 2-3 hours that people are reporting off other 5v 1A power adaptors.

[Q] Slow Charge

Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?

When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.

Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.

you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs

When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.

I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?

Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.

Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.

Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.

Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here

Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.

so this is nothing a kernel or any other tweak can fix?

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.

the 2A chargers from BlackBerry are the best

So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

USB charging

helo,
i love how it takes only 90 minutes for a full charge on wall with nexus (took captivate and infuse 3 hours...what an improvement !!!)
When i use my other usb cables on computer alone at work, it charges less than my infuse. do i need to buy an oem data cable? the one that came with phone is kept bedside
anyone know how long to charge your nexus via usb only? my infuse was 5 hours, 3 hours via wall
thanks !

i never charged my nexus from 0 to 100 via a normal USB port ... but it will be longer!
The USB power adapter that comes with the nexus pushes out 1A, where a normal USB port on a computer or any other device will give you 500mA MAX. which is only half the power.
Well - just try it...?
And no - the cable does not matter at all... (if it's not broken)

Check the output rating on your wall charger. My regular HTC Desire Z wall charger outputs 1amp, but real world you can get about 700mah output. I think I read somewhere that the Nexus charger outputs more.
The regular USB port on a PC however is normally rated for a max of 500mah. Realistically you can get about 250-300mah output instead. You can install Battery Monitor Widget, it's really good for monitoring these kinda stats

Battery or Phone?

Friends,
Interesting observation here. For the last week of owning the SGIV phone, my battery life is awesome, however when
it comes to charging it takes *forever*. When I mean forever, I don't mean two to three hours, like almost 8-9 to get a full
charge.
11:30am est battery was at 17%. At 3:30pm est, battery at 47%. when charging.
Any ideas if its the battery or phone?
please advise,
tvos

It shouldn't take that long to charge. Mine charges with a way higher rate. So I guess it's a problem with your phone /battery
Flowed from my GT-I9505 using xda-developers app

Proly an issue with the charger - i charged slowly from a computer outlet - but a couple hours later did the wall outlet (using a motorola charger and it was juiced up in a just few hours) - Might be related to the charger and/or usb cord in use.

Make sure you are using a 2A charger like the one that came with it

I was discussing this with a friend after I posted my concern.
Apparently, if you charge by usb from a computer source, the amp is lower hence, it will take three times longer.
If charged by wall outlet it won't take long for the phone to charge quickly.
Just in a half hour I decided to test this theory and it works faster at wall outlet.
Thanks people...

Use original charger in the wall outlet. Takes 2 hrs from 1%

not sure if this was mentioned in the FAQs and I did look.
Might want to add this in the FAQs - differences between the battery outlet charging vs. computer source.

Normal usb power is 5.1 volts at 1amp. Bigger battery chargers are normally 5.1 v but at 2amps.. that being tablet chargers and bigger battery devices.
Plugged into a comp and not into an outlet I think you get 1/2 an amp ( wayyy less then originally supplied and intended charger)
our s4 came with a 2amp charger. You can read the specs on the side of it.
if you were using a 1amp ac adapter which is what 90% of mobile phones have, then it would take significantly longer.
my battery charges in about a hour and twenty minutes using stock s4 charger and cable.

[Q] How long does it take to charge your LGOG?

Also what charger/wire are you using?
I got a used phone with the LG charger and wire but the wire was damaged so I am using an iphone charger plus a dollar store micro USB cable. The charge is painfully slow, I just did 40% in 2 hours.
What combination are you using and how long does it take to charge?

Don't forget original lg charger provides 5v at 1.2 amps. Use a bigger one and definetely not a cheap usb cable.

its normally takes 3.5 to 4.5 hours to take full charge from 10%, im using the stock charger but i change the usb cable because it was giving me problems.
So its my recommendation to change the usb cable an give a try.
