Overnight charging on AC

My G1 after I put him on charger goes till 100% and than act like it is not connected to any charger.
Like today it got to 100% and in the morning was on 98%.
I use AC wall charger for Motorola V3.
people tells me that is no problem, should be the same with miniUSB connected to PC.

I believe the default charing behavior of most rechargeable devices is
charge to 100% stop charging until the % is lower then a defined %
then charge to 100% once more

Do not use a moto V3 charger to charge your G1. It charges at a lower voltage and could effect your battery life. Use the one that came with the phone, another HTC charge or a blackberry charger. They all charge at the same voltage.

The only thing I see is the V3 charger has a lower amperage rating whereas the charger that came with the phone is capable of putting out 1A. It might be sending data at night and using more power than the V3 charger can put out.
First night I had my phone I had wifi and gps on with full screen brightness hooked up to the USB on my desktop PC and I was actually draining the battery while it was "charging" It's a power hungry phone when it wants to be. I would look into finding the factory charger.

usb can only charge at most usually 5v. Any miniusb charger will work for it, it wont overcharge it, it will only undercharge it. "smart circuits" if you will, tell the phone to shut off at a full charge, and like previous posts, to stop charging it, and when it reaches said threshold (98 percent) it will charge it, basically maintaining charge, without overcharging alltogether.

Actually, I can tell you that the mini USB charger for my Toshiba G900 will *not* charge my G1, but will charge other devices I have.

Slow charging

I get slow charging with the original charger can anyone help me? Thanks

If the phone is off use gsam battery to determine What's using your battery as you charge
Sent from my VS980 4G using XDA Premium 4 mobile app

Would that help if I get the slow charging icon in notification bar?
Even just posting on here it's discharging not doing anything else

AFAIK, the G2's definition of "slow charging" is any time it isn't getting (close to) a full 2A from the charger. This doesn't mean the phone isn't charging, or that it's going to take an excessive amount of time to charge. Other chargers will work fine. The Snapdragon 800 CPU supports fast charging, but the opposite of that isn't necessarily "slow".
One thing to watch out for is temperature. If the phone/battery is warm, unplug it for a little while, and maybe even turn it off to let it cool down. If it's too warm, it won't charge very well. I found this out the hard way recently when I left it on the original charger overnight, and it still hadn't gotten to 80% by morning.

Right OK thanks but should this really happen with original charger?

original cable too?

Yes original everything

Mine doesn't show slow charging if I use the original cable. I tried another cable with original charger, and it shows slow charging.

It seems like the "slow charging" depends only on the original cable which comes with the G2. I have used another USB cable with the original G2 wall plug and I still receive the indication of slow charging.
Why would LG do that? I could understand that the wall plug has to deliver a certain ampere but it shouldn't depend on the cable... (only apple would do such thing )

You have to remember that the 1.8 amp charger that comes with the phone would be considered a rapid charger for other phones. Which means the cable would have to be able to carry that amperage. The cables will always matter. If the cable is unable to carry the appropriate amount of electricity, a bigger, better cable is needed. It applies throughout electronics, not just to apple.

Charger Disappointment

Any one Disappointed with the charger they included with the Pure. The non removable cord just sucks and a poor choice in my opinion

I'm more disappointed at the size of the wall wart. They could have made more friendly to other power strip users.

Pretty sure they did that so you couldn't just stick any usb charging cord in their...it'd most likely fry it.

The disappointing part is the my other cords not working with Android auto. Luckily I have a nexus 6, and the cord with its charger works.

If you plugged in a charging cord that can't handle the increased power it sure could fry the cord. I feel ya though...it would be nice if it were a USB cord.

I'm glad it looks different.... My son knows NOT to plug his HTC M7 into this charger.
I can see if this was someones first Android, the lack of a micro-USB for data would be frustrating, but I have about 5 of these in my desk drawer and throughout my house and office, so it doesn't bother me.

Also having a fixed cord means you don't pulg some 'slow' cable in and not get any benefits. Out my 8-10 micro USB cables, only 2-3 get a decent charge speed.

If a device that does not do Turbo Charging is connected, the charger should automatically adjust and charge it at regular speed. At least, that's what it is supposed to do. The Turbo Charger is supposed to be the single charger for all types.

I think the reason they made the cable fixed is because a lot of cheaper usb cables use very thin wire gauges. Since this charger puts out a lot of current at varying voltages, it's very possible for a thin cable to overheat easier and catch on fire. And my guess is, they didn't want to take any chances

How do we determine if turbo charger is ongoing? I mean are there any indication? Coz when I plug in the TurboCharger that comes with it, sometimes TurboPower Connected shows at the bottom of the screen, sometimes not. Then when I check it on the Status, it says Charging over USB, not Charging over AC? Could be that my unit is defective? perhaps the charger? or the battery?

You can use a USB voltage/current indicator device to see it directly. I use one that displays voltage and current simultaneously, it cost about $10 on Amazon.
The Qualcomm QC 2.0 (which Motorola terms "TurboPower) spec is 5, 9, 12, and 20 volts, with up to 2 amps plus at each voltage. The QC 2.0 chargers I've tested including the Motorola charger included with the XT1575, range up to 9V and about 2+ A at 9V, with the higher voltage/amperage when battery is discharged to a lower SoC.. Haven't seen 12V or 20V, I think those only come into play when battery is discharged to nearly zero SoC.
Agree the reason the included charger has cable attached may be to ensure adequate wire gage. Too-thin wire will increase voltage drop across cable thus lengthening charge time in higher power modes. But the design here uses higher voltage to keep current down around the same 2A max current of USB 2.0 chargers, so cable heat will not be a problem with any old USB cable.
I will attest to the benefit of QC 2.0. I thought it was a useless gimmick until I started using it. It does effectively compensate for mediocre battery capacity.

My "Turbo Charging" icon displays properly, but doesn't charge very quickly if connected to a cheap extension cord.
Plugged into the wall, the charging Stull doesn't impress me that much

It's defective. Call moto they will replace it for free. Just have to send copy of purchase receipt. Had the same issue.

The charge rate depends on how discharged the battery is when connected to charge.
More discharged (lower SoC, State of Charge) will drive a higher charge rate.
As to the difference between this Motorola TurboPower (aka Qualcomm Quick Charge 2.0), vs. other phones:
I've measured up to 1.4 amps at 5V nominal on other phones, that is about 9 watts charging power. That is max charge rate, with a very discharged battery. As the battery charges up closer to fully charged, the charge rate (power) is reduced. Total charging time from fully discharged to fully charged would be about 4-5 hours, give or take, for a typical cellphone battery.
For comparison, the QC 2.0 measurements I made with the MXPE: Up to 2.2 amps at 9V nominal with a phone battery discharged to about 40-50%. That works out to about 20 watts charging power. As with other Li-Ion battery charging systems, this also declines as the battery approaches fully charged. Total time to charge, from fully discharged to fully charged will be about 2-3 hours, give or take.
So the marketing claims about QC 2.0 are about right: A 75% improvement over conventional charging systems.
The biggest gains come when charging batteries discharged to lower SoC. If you are comparing charge rate/time of batteries discharged to only, say, 70-80%, you will not see as much of a difference with QC 2.0.
I'm not a QC 2.0 marketing shill, mind you. I pretty much ignored it, before buying the phone. But for this phone, QC 2.0 actually does a good job to compensate for the mediocre battery. I can run the battery down to 40-50%, put it on QC 2.0 charger in my car for my 30 minute commute, and it is charged to around 80+% when I arrive at my destination. There are a lot of QC 2.0 certified aftermarket chargers out there too, Qualcomm did a lot of work on the front end as part of bringing it to market. (Just make sure any AC charger is UL listed or equivalent, if you care about safety.
Caveats on cables: The cable does make a difference at higher charge rates. Thinner gage wire will impose a greater voltage drop at higher current, this will reduce power and thus increase charge time.
Typical USB cables are AWG 26-28. You can buy 20, 22, and 24 AWG USB cables. Some cables advertise heavier (22-24) gage wire for the power leads with standard (26-28) gage wire for the data leads. The aftermarket QC 2.0 AC chargers I bought listed their included cables as 20 gage.
Get the heavier gage if you want full QC 2.0 charging.

Fast charging with 2A charger

Hi
I am planning to buy this phone.
Can anybody confirm if faster charging is possible with a 2A non stock charger? How much time does it take to reach 100 percent?

The phone doesn't have fast charge
For me, it takes 1h 30m to charge from 0% to 100%

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...
Sent from my iPhone using Tapatalk

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...

2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.

Mobile takes more time to charge?

My device is taking more time to get full charge. Is anyone experiencing the same.is there any way to improve the charging

My device is taking around 3 hrs to charge fully which is quite normal as given it has 5000 mAh battery and no fast charging. Only way to improve could be to switch off and then charge or not use phone while charging. Disabling cellular data and WiFi may also help.

Does it show "Charging Rapidly" state on the lock screen?
On my Anker triple ports QC2.0 charger, 2 of the normal ports 5V2.4A are able to "induce" my M2 phone to go into "Charging Rapidly" state. It only happens after plugging in for a few mins; if plug into the QC2.0 5V2A port it doesn't display "Charging Rapidly", just shows the normal "charging". Another of my QC3.0 charger 5V3A is also able to do this while other chargers I tried from 1.8A-2A range can't get this "Charging Rapidly" state. Is it possible that the M2 only support "fast charging" on 2.1A and above chargers?

No... Actually the speed of charging also depends on the current... If you current is 2A, then it automatically shows charging rapidly...
If you use any other charger with a lower ampere rating, then the phone will automatically detect that the current is low and it is charging slower...

Why do you say it will heat up a lot? Phones nowadays should have protection circuit to limit current, right? For my M2 I don't see any difference in using 5V2A or 5V3A adapter.

Its charger is rated 5V 1.55A... But when I use a 5V 2A charger, the phone starts heating up...
Though it happens only while charge is less than 100...
Upon reaching 100% it cools down...
