Is it the battery or the charger that gives fast charging in smartphones?
Unless the MotoG is not a certified USB device, then it has 500mA on the charging port at any given time.Quick charging is a technique for the wall charge power-supply (which is a switching power-supply) to oscillate at a frequency that is conducive to a safe charge, unless its on a monitored port (like on a computer) then it gets 5v.Everyone wants a faster charging battery...until a quick-charge (which usually ends at about the 70%-80% mark gets pushed too far and an overcharge condition pushes the cell overheat and rupture.There are newet technologies that are implemented into the charging circuit that give the handset the ability to adjust the voltage in more incrmental steps when it is feasible to do so. Having more insight into the charging environment with better sensors, temperature and pressure mems, a data stream that has a higher resolution into the operating state of a battery in quick-charge allow a reactive contingency to deploy if there is any negative reaction to the current charge profile. So instead of having small brakes on a big truck that has 2 speeds where you drive slow and have to plan ahead to stop if something goes wrong, you can have a truck that has 5 speeds to granularly adjust as you are planning ahead more because more monitoring is going on.
If I charge my Moto G (2nd gen) using a 2.1A charger, will it affect my battery and battery life?
You might think that all chargers are created equally, but nothing could be further from the truth. Wired explains that picking the right charger with the right amperage (a measure of current) can mean the difference between getting your phone charged while you work versus waiting all day before you can unplug it.I use this one: AC Power Adapter ChargerThis isn't as simple as just "charge your device with the charger it shipped with." You can actually use higher amperage chargers, like the kind that come with tablets, to get your phone charged up in less time than it would if you charged via USB or using the charger the phone came with, and it won't cause a problem. Here's how it breaks down:For example, consider these charging scenarios for the Retina iPad mini. You could use a Lightning connector plugged into a computer (via USB), an iPhone charger connected to a wall socket, or an iPad charger connected to a wall socket. A PC USB charger delivers 2.5 Watts of power (5 volts at 500 mA). An iPhone charger delivers 5 Watts (5 volts at 1000 mA). A Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA).While all of these will charge your iPad, using the USB connected to a PC will charge your Retina mini four times slower than if you used the iPad charger it came with. Conversely, if you use the iPad charger for your iPhone, it’d charge up faster than normal. If you play mix-and-match with these types of chargers like this, don’t worry — you’re not going to blow up your phone or anything crazy like that. And the myth that charging your device at a faster rate will reduce the life of your device’s battery is false. For some older devices, the higher specced charger just won’t work at all, while newer devices will just charge faster.Ultimately, it’s really the amperage that determines how fast a charger will supply power to your device. If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts (or whatever voltage the device you’re trying to charge is specced at).If you have a background in electrical engineering or physics, this makes sense to you. P(ower) = I(current)V(voltage), after all. For the rest of us though, look for good, reliable chargers that offer high amperage and use the same connectors as the device you're trying to charge. If you have a good, high amperage charger, you can cut down on your overall charging time.

Should lithium-ion batteries be taken off the charger when fully charged?
It's my understanding that electric storage in lithium-ion batteries is a dangerous, thing, but, with constant monitoring and measurement of temperatures, it has been made safe. It's also my understanding that it's very bad to over-charge a lithium-ion battery. Lacking actual facts I've been assuming that since my phone pops up a notice stating that it knows my battery is fully charged, that the electronics in this in this ultra-powerful multi-gigahertz marvel of technology would be smart enough to stop sending power to a battery that is fully charged.My newest phone, Samsung Note 4 actually says I should take it off the charger. He're my concern, rechargeable batteries have a limited number of cycles, in my mind every time you discharge that battery you are doing a little damage to it. Isn't it better to have the phone on the charger?Is my assumption that the phone can be powered without destroying the battery correct? Should I write up a patent for this unique idea that nobody has every thought of before? Or is Samsung just being slimy and trying to sell more batteries.
My beats studio wireless headphones won't charge, or turn on.?
So my headphones started out with a red circle by the charging bar. After the power ran out, they won't charge, or turn on. Usually when it's charging, the white bars will go up. That's not the case. The red dot won't show up now. There is no indication that there is any power whatsoever. It won't reset either by holding the on and mute button. Any advice? Thanks.
Why is my car battery light on with a new battery and alternator is charging?
It could be an issue with wiring. How old is your car?I had a 1995 Century that had the exact oposite problem (Battery light stopped coming on wgen you turn on the key). I never had any problems with drivability or anything like that, and drove the car for months without that light. I did eventually troubleshoot and I found that the small wire going to the voltage regulator on the back of the alternator had come loose - I had repaced that pigtail a year prior, and just didn't do as good of a job as I should have done. After fixing the wire, the battery light was working again.It could be a loose connection at the battery or alternator, or even a bad ground somewhere. Check that your battery cables are clean and tight, check that your negative cable between the battery and the car is clean and tight. Check that your ground cable (or grounding strap) between the body and the engine are clean and tight, and make sure the bolts on the alternator are snug as the alternator grounds to the engine this way. While you're there, make sure that your battery cable coming from the back of the alternator is snug (it will be the large red cable, usualy connected to the alternaot with a bolt), and the other connector is not loose. Look for any damage to the wires that could be shorting out against the body or engine. You don't have to pull the wiring loom apart, since usually, if the loom isn't damaged, the wires inside should be ok (not always, but you're pretty much just doing a visual check of everything). If you cannot find anything, or find something that you do not feel comfortable fixing yourself, take it to a mechanic you trust.
