[Q] Can I use my Galaxy S4 Charging block....

with the included Moto G USB cable to charge the phone? Obviously, the G doesn't come with a wall adapter so I was wondering if this will be OK - i.e. same voltage, etc. - and not fry the battery.
Thanks

Once i read that most new batteries (since 4 year ago to now) can use different chargers with higher amperage without being damaged, o i think you can. i think thats why they don't include charger, because most people already have one at home.

Fast charging causes reduction of long-term battery capacity

My response here to the above answer is what I understand as a layperson who has recently done internet research into this issue of which power adapters would be ok to use with the Moto G. I will be happy to stand corrected by anyone who has contradictory authoritative information.
My understanding is based on the Battery University website entries on lithium ion batteries:
batteryuniversity.com/learn/article/charging_lithium_ion_batteries
batteryuniversity.com/learn/article/ultra_fast_chargers
Although the above quoted answer on using the Galaxy S4 charger with the Moto G is mainly correct (in that no direct damage to the phone circuitry or immediate damage to the battery will occur by using the higher amperage charger), there still will be a long-term negative affect on battery capacity by using a higher amperage charger.
I believe the S4 comes with a 2A charger. According to Motorola online support website
( motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/97318/p/30,6720,9050/action/auth )
the Moto G will automatically restrict charging above 1500mA. So that would mean that a 2A charger would cause the Moto G to charge at the 1500mA rate. No damage would be done to the phone circuitry charging at the allowable rate of 1500mA, but the question remains if there would be a long-term reduction of battery capacity by charging at 1500mA for a year or more. The official Motorola charger sold online is now 1200mA. So the comparison should be between charging at 1200mA versus 1500mA.
According to the Battery University website, the optimal range to charge lithium ion batteries is between .5C and .7C. Lower charging rates result in less reduction over time of battery capacity. The C-rate unit is used to measure charging and discharging rates. A value of 1C is equal to the rated amperage of the battery. So, for the Moto G, 1C is equal to 2070mA. Therefore, according to this recommendation, the optimal charging range for the Moto G would be between .5 x 2070 = 1035mA and .7 x 2070 = 1449mA. So, charging at the Moto G's maximum of 1500mA would be just barely outside the optimal range.
But extrapolation from Figure 1 in the Battery University 'Fast and Ultra-Fast Chargers' article indicates that there would be an additional 9% reduction of battery capacity by charging at a 300mA higher rate of 1500mA over the official charger rate of 1200mA. This additional reduction in capacity of 9% would be over 500 charging cycles, or about 1.5 years of average usage. The normal reduction in capacity just from aging over 500 cycles is already listed as 16%, so adding the 9% would bring it to a total of 25% loss of battery capacity after about 1.5 years.
--------------------------------------------------
UPDATE and CORRECTION:
I have more authoritative information directly from Battery University that changes the conclusion I draw above based on my effort to extrapolate from the Battery University website article.
The extrapolation I did above was based on the additional loss of battery capacity cited when going from a 1C to 2C charging rate. But according to direct communication from Battery University, when charging at a rate below .7C there should be no measurable improvement to capacity by using slower charging rates. Charging above .7C would still be expected to add more stress to Lithium Ion Polymer batteries and likely add to long-term reduction of capacity.
So, what this means for the Moto G and Nexus 5 is that there should be no measurable difference between charging with 2A, 1.2A, 1A, or 850mA chargers as far as effect on long-term battery capacity goes. Both the Moto G and Nexus 5 are supposed to automatically restrict the charge rate at 1500mA even when using a faster charger, which is just at or below .7C for both phones. So, as long as the charger dependably keeps to 5V, a higher amperage 2A charger will be faster but pose no problem to long-term capacity.

[Q] How long should it take for my Moto G to be charged?

Hello. I bought a Moto G two weeks ago and I got a 5V - 1A(output) charger for it. It took about 2.5 - 3 hours to fully charge it. My charger broke and I bought another one today with an output of 700mA( at least this is what was written on it) and I noticed it was charging my phone very slow, about 3% per 10 min( 96% for 5 hours, if you calculate it). I brought it back to the seller for that reason(even though the seller insisted that it was better for the battery to be charged slow). What kind of charger should I buy? And how long should my phone take to charge(optimal time) ?

You can calculate this. Battery is 2070mAh, which means if you have 1A (1000mA) charger it should take about 2 hours. if you have 700mA charger it should be full in about 3 hours. That's in theory. In reality it takes a bit more due to efficiency of charging process.

With a 10v wall charger and Moto G default charging cable, 1h and 30 minutes maximum. This is for when the battery is at 0 percent.

And the phone still consumes energy if it is turned on, or being used during charging.

Does this still apply when charging from PC with original charging Motorola charging cable?

I charge mine in about an hour and 30/50 minutes.

Yes it does, because charging from pc only gives you 0.5 amps i.e if you're using a USB2.0

[Q] Buy a new charger or not?

Got my new moto g yesterday and its damn good but the thing that frustrates me is the charging, I got a charger with 550mA output and it takes about 4 hours to charge from scratch. I am thinking to buy a new charger and read somewhere that the max cap is of a 1.5A power supply, I need to know how much power supply should I have for maximum battery years. Should it be 1.5A or my current charger or something in between like 1200mA. Thanks in advance.

It really depends on the electronics circuit inside the moto g and also on the one in the battery.Motorola says max recommended is 1,5Ah.I`m using an HTC charger (the old ones) with 1Ah / 5V rating , its charging it for about 2hrs.Also tried with Sony 880 charger (1,5Ah, and it took ~1hr and 30 min.But what I can tell you is that if the charger is high quality one, they all follow the 2( 3 ) step charging in a nice parabola.
If I were you , I would have gotten something with higher amps, like at least 0,9-1,2 at least, cos waiting 4hrs for it to charge is a pain, otherwise it wont be a problem for the batter at all.

A slow charge is likely to be best for overall battery longevity so as a balance I'd go for something around the 1amp mark. I use a .75a Blackberry Charger - takes 3hrs to fully charge from empty.

Moto G Charging Slow

I recently bought a new Moto G (Indian Version). But I noticed that it charges too slow. It takes about 3 hours to charge fully. Should I replace my charger?

Its normal, that charger has very low current rating. If you want to decrease the duration, use a charger with a higher rating, the phone can take upto 1.5A.

Max Charging rate (mAh) of Moto G Eka Falcon

I've seen on different post , many said it can charge max 1.5 A. or 1500mAh .
but i'm not getting that charging rate , tried out different 1.5 A. and 2.1 A. charger. on Stock Rom/Custom Rom/Kitkat rom.... nowhere.
I've found max rate on
Amphere: 930mAh
Battery (apps): 1120 mAh.
plz post here charging rate of ur one.
**sorry for my english

Plz reply this post buddies..... i need info cause my MOTO G Takes maximum 1100 mAh or 1.1 A...

I have tried many chargers , currently using a 2.1A charger - full charge in 1 hour.
I think amperage of falcon is around ~1.5A
Apart from the charger the quality (esp. thickness) of the cable also matters. I have used bad quality thin cables with 2.1A charger and it takes more than 5 hours to charge - so I bought a high quality charging cable

have u measure current with any app??
ok thanks for ur thought. um now testing with various cable.

is there any patch or tweak to charge about 1500mAh??
plz share screenshot or max charging rate of ur's. cause its hard to believe our Falcon can take 1.5A current flow.
