Default Nexus 5 doesn't take advantage of "Quick Charge"?

People are saying the phone takes 1:50-2:00 hours to charge with a 2300 mah , the LG G2 which also has a snapdragon 800 takes around 1:30 to charge with a considerably larger 3000 mah battery , the nexus 5 comes with a 1.2A charger ( the G2 comes with 1.8A charger) so maybe that's the reason, but does it support quick charge at all? Google/LG just decided to save some cents and threw a cheaper charger on the box? If I buy a 2.0A charger would I be able to use it and would the phone charge noticeably faster?

Most probably Not.
I think the Situation is a different too. LG uses its newly invented battery Type with enhanced Features. including massively improved recharging cycles.
Goggle does Not. and its known to batteries. the faster you load the quicker they die. no matter what they say. even eneloops are prooven to die much quicker when generally loaded at Max speed.

I have a Sony Tablet z charger with 1500mAh loading and a Asus me 301t loader with 2000mAh loading speed.
After some cycles I'll try them to See any difference but im sure there wont be.
DONT USE ANY FAST CHARGERS WITHIN THE FIRST (Minimum THREE) CHARGES.
Not to Do so is said to seriously harm any battery.

If a quick charger could harm the battery it could also charge the phone quicker which it won't because the phone regulates the battery charging process and doesn't really care if the charger is able to output >1.2A . It would make a difference if you charge your phone on a <1.2A charger of course.

If it wouldn't work that way you couldn't charge a friends 3 year old Smartphone on your wall charger

My old HTC Desire S 1450mah battery used to take 2.5-3 hours to charge. My N5 takes around 2 hours.

That is why I said it most probably wonīt make any difference too.
Usually phones do limit the charging power. I donīt know any device that does not. But I would be carefull with this chinese stuff
This is why my Galaxy Note wont charge any faster than with its original charger at 1000mah.
It is even possible that the Nexus only loads at 1000mah and the loader hast a little backup. But not very likely either.

When it comes to my Note...when I remove the battery there is a sticker where it is stated what is used:
5VA 1000mah.

So we canīt do that with our nexus

Grab your (Handbuch) User manual and look up if there is any information about it.


The quick charger thing...correct...I may have gone little overboard with my warning thinking myself it wont make a difference.
But you really should keep that in mind for your mignons ect.

Quick charge is built into the Snapdragon 800 processor. Qualcomm announces it like a feature but no manufacturer uses it, probably because the N5 is only the third phone to come packing the S800. It'll be up to Qualcomm to release a patch (like they said they would) so that we can utilize the quick charge feature.

Interestingly, none of these announcements address the effect on battery capacity long term

I refer to my (non-scientific) test conducted using the G2, S4 and N5 for charging performance. They're all pretty much the same, but the G2 was the fastest to charge.

I let all the phones run down overnight to 0% using the battery drain app from Play store. I then used the charger and cable that came with each device, here are the results - interesting test.
N5 - 2,300mah battery, 5.6V / 1.2A charger
S4 - 2,600mah battery, 5.0V / 2.0A charger
G2 - 3,000mah battery, 5.0V / 1.8A charger

Hi

Looking at the service manual the charging is handled by a Texas Instruments chip http://www.ti.com/product/bq24192. QuickCharge is a function of the Qualcom PM8941 power management chip, however as the Qualcom chip isn't charging the battery (the BQ24192 is doing this) then QuickCharge can't be implemented by a firmware update.

Regards

Phil

only thing speaking for a stronger charger would be the parallel usage of the device while charging it.
at least in my Imagination. dont Know if its technically possible if that could make a difference, but i think so.

charging my Xperia z is much quicker if i dont Touch it while its charging.
