I'm wondering if the heat I hear about being generated before the charging rate slows down after 50% would have any negative impact on battery life. Would there be any benefit in using my multi-port charger for overnight charges when I am not in a hurry to charge the battery?
Also, I assume that the battery doesn't have any memory, and that there's no reason to break it in, fully discharge periodically, etc. and that it's okay to charge a little or a lot regardless of the current charge state. Is that correct?
This is a question i would like to know the answer to as well
I did a slow charge last night and the battery seemed to discharge s little slower this morning fwiw, but that's not terribly scientific.

Fast Charging Lithium = Battery damage. It's basic chemistry. The cells take mechanical damage from expanding too quickly. So, for best longevity, charge her with like a .7 to 1 amp charger.

wrong. the only thing that damages cells is charging beyond the voltage specifications. How fast you dump electrons in has no negative effects, its only when you put too many in that batteries get damaged.

Thank you. I had thought the same thing. No one had the time to give me any detailed information, so I researched. I can't post links, but the following articles are helpful and will show up first in a search for the title
'Will speed chargers kill your battery?'
'BU-401a: Fast and Ultra-fast Chargers'
A conventional phone charger can only supply the current and voltage that is safe for a battery at all charge levels. In other words, it is must use the least common denominator. Quick Charge makes this process much more active by monitoring max current, max voltage, and temperature so that it can supply more power when it is safe and less power when it is not. Quick Charge will always keep the current, voltage, and temperature within the battery's designed specifications.
In terms of battery memory effect, no, modern lithium based batteries do not have any sort of memory-like effect. This is mostly associated with older and cheaper NiCad type batteries. This is one of those things that people seem to have a really hard time moving past.
People worry far too much about babying their battery.
Assuming you are going to use the phone for ~2 years then a properly designed fast charger should have a negligible effect on battery life. After 2 years of continuous usage all bets are off whether you used a fast charger or not.
If you really want to worry about how to treat your battery then there are two things you should try not to do. Don't let the battery go all the way to 0% and let it sit like that for a year. Don't leave your phone on your dash in direct sunlight everyday. Outside of those two things there's not much you can do to change the lifetime of your battery so just use the damn thing. =P

I had researched the topic and learned what you have stated, but I really appreciate you taking the time to write this fuller explanation. I wished to take every reasonable precaution to maximize battery life, given the battery is not easily replaced.
There have been references published claiming that charging faster (higher current) shortens overall Li-Ion battery life.
Mechanism may be related to heat.
One thing the Qualcomm Quick Charge 2.0 (used in the Snapdragon 808) does is increase voltage at the charger from standard USB 5V, to 9V and 12V, for higher charge rates (power) at still-moderate current (to keep heat dissipation down).
I measured 1.1 to 2.3 amps at ~9V with QC 2.0 charger on the MXPE, with the higher current measurements at lower State of Charge (SoC). Have not seen 12V yet, but I only tried it down to 45% SoC (2.3 amps at 9V), I imagine it bumps up to 12V when the battery is discharged further, nearer to complete discharge.
This charger is rated for
5V, 4A
9V, 2.22A
12V, 2.5A
20V, 1.0A
So the max power fed to the battery would be 28W (12V*2.5A).
(This is the Power Partners PEAW30-12-USB, supposedly a 30W charger. So much for integrity in advertising.)
So the current is kept to a manageable level to control heat dissipation (therefore max temperatures), from the charger to (somewhere in the phone). But I believe that at the battery itself, more rapid charging (higher power) would still require higher current, because voltages have to be limited in the battery itself, so one would think heat dissipation (> max temperatures) would still be a problem in the battery itself. Does that shorten battery life?
The answer is probably: Who cares. Because: Li-Ion batteries have a 2-3 year life in any case, regardless of their service life or even if they are not used at all. They age and exhibit substantial capacity decline over time. Discharge/charge cycles hasten the capacity decline, but the battery is only good for 2-3 years, give or take, no matter what. And since aftermarket replacement batteries are inferior, unsafe, and stale, there is no reason to try to hang on to your phone for more than 2-3 years in any case. (Especially since the "non-user-replaceable" batteries can be a pain in the a** to R&R. The Moto X Pure 2015 battery is one of those. Some phones actually incur permanent damage to seals if the battery is removed/replaced - the Kyocera Hydro Wave is this way.)
You say "but you could replace the battery with an OEM battery". There are two types of OEM Li-Ion phone batteries on the market that an individual consumer can buy retail, when their phone is 2 years old or more: Used stale batteries (look up "reverse logistics"), and "new" (i.e. not put into service yet) stale batteries. Good luck finding a fresh, new OEM Li-Ion battery for your 2 year old or older phone (out of production for at least a year).
Been down this road before. Wasted lots of time and money replacing phone batteries after 2-3 years. From now on I'm going to stop coddling phone batteries, stop replacing them after 2-3 years, and just figure on a new phone every 2-3 years. It's the only way to get a fresh, new Li-Ion phone battery. (And get the phone right when it is released, like the MXPE this month. That way you are more sure the battery is fresh.)
I think everything in the wireless phone paradigm is increasingly heading that way anyway. Everything, and I mean everything, pushes the market to a 2 year product life cycle. Batteries last 2 years. Increasingly, batteries are not made to be replaceable. Carriers are changing networks so fast you need a new phone every 2 for that alone. New OS/SW overloads hardware older than 2 years. Displays may fade over a couple years. USB connectors wear out. Just relax and go with it. Marvel at the Qualcomm Quick Charge 2.0 (I am). You'll be happier with a new phone every 2 years.
Sorry for the long rant.

Yes, the Moto Turbo Charger can be used with any MicroUSB charging device. It will adjust charging as needed for the individual device. Moto made the Turbo Charger, to be a single charger for all MicroUSB devices.
If the battery is kept well charged, which Turbo Charging helps to accomplish. That's better to me, than more drain and slower chargers that leave the battery more drained overall. The batteries are supposed to last longer when kept fully charged more often.

"...since Quick Charge 2.0 is compatible and interoperable, a certified adapter can be used with a non-Quick Charge 2.0 device, though the fast charging benefits of Quick Charge 2.0 will not be available. "
https://www.qualcomm.com/products/snapdragon/quick-charge/faq
By all appearances, Motorola's "TurboPower™ Charging" is nothing more than Qualcomm Quick Charge 2.0. (That's what Snapdragon 808 in the XT1575 uses.)
The third-party Qualcomm Quick Charge 2.0 chargers I bought are recognized as "Turbo" and function with the XT1575, just like the Motorola charger that came with the XT1575.
(There are a LOT of Qualcomm-certified QC 2.0 chargers for sale by third-party names. Qualcomm has been BUSY. )
To slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?

Moto doesn't have the option in settings, it uses industry standard Qualcomm Quick Charge standard rather than a OS hack like Samsung (no offense)... If it is connected to a QC 2.0 charger, it will negotiate the appropriate charge rate, if it is connected to a "standard" charger it will charge normally.
I don't think you can accurately measure battery/charge cycles... even if you could it would be extremely deceiving, what would be considered a cycle? Charging at 50%, 30%, 10%, and to what point 75%, 80%, 100%? Too much room for interpretation here that could be swayed either way depending on the person/app counting it's point of view.

Thanks for replying dear. So, for S7 I have turned off fast charge, should I now charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
For Moto G, the question is the same as above.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?
And I have signed your petition Brother. I hope they listen to the users.

Does Fast Charge hurt the battery life, no, at least not directly... heat does. Using an older style charger will avoid Quick Charging but I think that foregoing that benefit for a few more days of battery life is hardly worth it. I frequently have 30-60 minutes to charge, not 3-5 hours, so quick charge is nice, if it takes few days off the longevity of the battery so be it. Those who think it cuts the battery life by 20, 30, even 50% are wrong, that simply isn't the case because of Fast Charge itself.
The Moto G isn't an issue here, it doesn't support Quick Charge until the 4th generation, but why give up the feature?
I don't think the "rules" of charging apply as much as people think they do... I charge mine overnight and whenever it needs it during the day, if it does. There is no need to do anything special.

Thanks for the wonderful and detailed reply. I am going to try, not stick, to slow charging to see the difference in heating of the battery. My SIII's charger 's input is 150-300VAC, 50-60 hz 0.15AA, output- 5.0V-1.0A and S7's details are input 100-240V 50-60hz 0.5A, output- 9.0V= 1.67 A or 5.0V=2.0A. Can I use the S3's charger to charge S7 after turning of fast charge or is there a voltage difference or something? G4 is at home, don't know about its details. Also in my country the battery or the replacement parts are way too expensive.
Hi,
I was video calling someone for a group project, and I was using a regular (not turbo) charger to charge my phone while i was at it. when I started, my phone was at 5%. Then it went to 0% and died, even though the charger was still plugged in. Is there any way to stop it from losing charge while its plugged in like this?
Use a faster charger. 5V 1A is fine to charge it when not in use but if you use it intensively like you did (screen on and high network usage) it is not enough. I would use at minimum a 5V 2A or the turbo charger.

You are mostly right, but the phone will not draw in excess of about 1200mA from any non-turbo charger, a larger charger is not important and will give no gain, but it doesn't hurt anything either.
The Moto X has a very large current draw off the battery when using the display actively, and at high brightness it gets almost ridiculously high, and add in intensive networking, high CPU usage (encode/decode video streams in real-time), and the power draw can easily exceed 1A or even more, so I am not surprised the battery drained while connected.
I am not an advocate of Turbo charging either, Qualcomm Quick Charge 2.0 can be hard on batteries, not in itself but the heat build up while using the device and turbo charging at the same time can easily exceed acceptable thresholds, but sometimes it is necessary with this device.

I remember reading that quick charge is deactivated when the screen is on (reverting back to 5V) to avoid overheating so I don't see using the turbocharger when using the phone as worst than any other charger or any better for that matter.
But yes, he shouldn't have started his chat with a MXPE at 5% battery left .

Hmm... I hadn't heard that but it makes perfect sense. Personally, I am usually looking for a charger if my phone falls under 40% unless it's within a few hours of bed time.
Hey all,
I was wondering what you guys think of the following:
Is it better for your battery to use the stock 3 amp charger all the time or is it better to charge it more slowly with an 2 amp charger? In my thoughts, slow charging is better for the battery. What do you think?
Slower is better.

Use a USB-C 5V 3A charger. If you monitor your charging amps you will only ever see 3A when fully discharged and it then tapers off to less than 0.5 amp when close to full. Suit yourself, but I'm using USB-C chargers designed for the phone.

Since the battery of the 6p degrades very fast, I was interested if people here would think using a 2 amp charger would help stay the battery in better condition.

As mentioned earlier the charging current is not constant and is regulated by the phone. The fast-charging phase of the charging cycle only runs up to ~40% battery capacity and then tapers off. If you doubt this, you can simply install any program that monitors charging current (eg. Accubattery) and see for yourself. See the Accessories sub-forum or the "Charge Time" section here for more information.

I know that. I'm monitoring the charge speed with accubattery. When under 40% it charges up to 2900 mah, and when it gets higher it goes down to around 2000mah. Average charging speed for last charge (20%-80%) was around 2550 mah. I know that's normal for normal phones, but I was wondering if it would help if I would use a 2 amp charger, to slow the charging down. Only because our nexus 6p stock batteries seem to be quite crappy.
So, I know the charge rate is fine if the battery would be of good quality, but it seems that ours are not.

This has been discussed, it's not charging any faster than it did in Nougat. All they did was add the text to tell you it was fast charging, which to them means charging above 1A. True fast charging would be 50% in less than 30 minutes, definitely this update is not going to do that, no matter what charger you use.
But after oreo update there is a little improvement in charging speed... I charged my A1 in switched off and phones charged in 1hr 35 min from 0 to 100%...and i used the stock charger...

Doing some very basic math.
3000mAh battery.
Charging rate of 2000mAh
That would equate, if the battery were truly at 0%, and charged truly to 100% full 3000mAh capacity, of 90 minutes, in an ideal world. Of course, there are some things that come into play, such as overhead.
With my USB measuring tool, I am able to see the voltage around 5.10-5.20v, and the amperage around 1.85-1.94A. This is with a Qualcomm QuickCharge 3.0 charger, so I know for certain that it is not doing a higher voltage charge. I can also see that it is not doing a higher amperage charge.
Given this, I will have to see about doing a complete drain on the phone, and then charging, and seeing where 100% is indicated on the phone, in terms of capacity, as my tool can measure the amount sent over USB as well.
Hi all,
I got OnePlus wall Fast Charge Power Adapter from ebay, and i test it with factory cable, i found its higher then the official one
the official one its between 1730 -1800
and the after market from ebay Ebay its between 2700 -2900 my question is the higher amp will hurt the battery life ?
regards
How are you measuring this? Ive found my One plus phones will not charge rapidly with my current measuring device plugged between them and the phone.
Next every single device I have, the battery lasts longer when I slow charge them. (More time on each charge) I charge my devices generally between 0.3-0.5 amps.

The charger uses 5V 4Amps. You should charge around 3000mAh below 75% after they it slows down.
