Im not sure if this is a silly question, but i have been using a usb hub to charge my phone for the past few months and i only get a 1 day charge with it, if i were to use one of the apple wall chargers, or the official htc wall charger, will i get more battery life?
thanks in advance

no u will not, because it is not the charger who dictates amount of charged electricity in batery, software is a key for batery endurance

both but bear in mind that i use an extention for the usb as it is too short
and also a usb wall charger not from htc if they make a difference
They probably do. Try to find original HTC charger and charge your device without extension cable.
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.

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.

mine seems to charge to slow, or maybe cuz im not using the stock cable and im using my usb ports on computer
but if i have stock charger on wall outlet, how long is the charge top up take from 10% to 100%, thanks
yea mine is charging slow through the computer but I dont know if its because of the nexus 4 usb cable im using.

Obviously charging through a 500mAh USB 2.0 port would be slower then through a 1.35A wall charger.
can I use 2A charger?
Yes you can use a 2amp charger I was using my S4's and it charged fast
Sent from my totally stock Nexus 7 FHD
Interesting, I've only charged mine twice since getting it last sunday, and I've not paid any attention as to how long it's actually taking, one was through a proper charger, and finally today plugged into my computer
The New N7 ships with a 1.3 amp charger, and it's definitely slower to charge than the old N7 (which shipped with a 2.1 amp supply).
But I have yet to determine if putting a higher current supply on the new N7 will result in more current being delivered than the stock charger.

It takes about 3 hours to charge from 0% to 100% with the charger it came with. Using a 2 amp charger doesn't decrease the time, as the device will charge at a maximum of about 1100-1200 mAh.

Android Tuner battery history.
Can anyone tell me what the power draw should be using the stock charger and cable?
Battery monitor is telling me that it is +237ma, it is taking 12 hours to charge. I have sent back to Asus via PC world (what possessed me to buy from there I dont know) and they have told me there is nothing wrong with the device. I have flashed the stock image and still getting notoriously slow charge times.

With the stock charger and cable, the battery should be charging with close to 1200mA; the charger draws 7.4W from the outlet (at 230V).
There is current limiting based on the voltage the tablet sees, a USB cable with thin wires can drastically limit the charge current.
hi how much times it takes to your phone to fully charge mine with the S5 charger and a 2 meter aftermarket cable took 4 hours one time and another time took 3 hours. is the charger or the cable to blame?

Mine needs 2 h +/- with a 1A Samsung charger and a LG G2 cable.

Chargers range from 1A-2A output. The cable will also affect the charge speed. I tried replacing the cable on my Samsung charger with a cheapo $1 one, and it wouldn't charge for crap. Swapped it out for a higher quality one, and it worked great.
I might keep my note 3 charger for this. Usually charge quickly.
The G3 comes with a 1.5a charger and takes about an hour and a hlaf from 18% to 100%. Would using a 2a charger cause any damage to the battery or would ut be safe to use?

Should be fine. I've used my 2A Samsung charger on several phones with no problem.

My AT&T G3 came with a 1.8A charger. It's a lot bigger than I expected. Charges my phone in about 2.5 hours.

Tmo variant ships with a 1.8A as well. Not sure what you've got that came with a 1.5A. Charges in about an hour and a half with my longer cable I've got at home and 2A samsung charger I have at home. I don't use the LG one it came with because it's too tall. It's about double the depth of the charger that I currently use and I've got it crammed behind a file cabinet. Also the cable coming off the end of the charger instead of the side is a poor design considering that the charger is already so deep to start with. The charger it came with definitely wouldn't fit back there.

I just checked again and its a 1.8 :silly:
i read on a review that the charge times may vary from 2 hours to 3 hours
Hi everybody! With the originale charger and cable my G3 has a very, very long charge time. About 4 hours or even more... One morning I found it at 92% after all night (from 00.30 am to 7.00 am).
What do you think it depends on? May I have some hw issues? Now I use another charger (not LG's, about 2a) and it takes about 3 hours...
I'm going crazy about it! Thanks...
hi guys.I used to charge my phone whole night so I did not really pay attention how much time it needed to charge full but for morning it was ready.so I decided yesterday to charge.it was evening and I noticed that it to very long time I unpluged it after maybe 4 hours and it was on 58%.Now I am charging it and it took more than 4 hours to reach 100%.have any ideas how can I fix it?battery life was 4 4.5 hours of screen usage lattely.can it be bocouse I used to leave it at night?

They can may a difference, even when transferring files or flashing and chargingI don't have empirical data, it's just my personal experience with android phones over the years.

There are lots of different quality USB cables. I had a rubbish one that actually discharged instead of charging it was that bad.
Get different cables (try and borrow your friends' cables) and run the app Galaxy Charging Current from the play store. This will give a charge current trading for your cable/psu combination. If your psu is a genuine 2.0 Samsung charger then a good USB cable should charge at 1900mA. Rubbish ones can be anywhere from 100mA worse than charging over USB from a computer) upwards.
