Hi guys, some days ago I installed "Android Tuner Free" which has a battery section that shows you many things like the charging rate.
Here is the question, Should it display 1A or 1.2 like the value on the battery charger or it may vary?
If I obtain about 700mah should it be a charger issue?
Thanks :good:

the 1 or 1.2A is what the charger can supply. Typically chargers can supply more than what a phone can draw, which is the real question.
Looking through my charge/discharge history with Battery Monitor Widget, I see a few values above 725mAh (the phone will draw more current when the battery is empty, so I guess the upper limit will be around there).
Your case seems normal to me.

Hi guys,
N910C with Exynos here.
I have some questions for you guys.
1) Is it beneficial to use a generic (but good) 1/2 A (amp) 5 V (volts) charger over the Samsung charger?
2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?
3) When using the provided Samsung charger, is it better for the battery to leave the "fast charge" option off?
4) Is the fast charge (or any fast charged charge) as good and efficient(?) as a 'slow' charge? Will they last the same?
5) What if I turn off the phone, is it going to "fast charge" by default when using the the provided charger?
Thanks in advance guys!

No. It won't do any harm, it will just take more time to charge your Note.
2) What happens if I leave "fast charge" option on? Will it charge faster? Will it try to?

It will charge slowly. Reason: Fast charging uses a slightly higher voltage for transferring the charge to the charging circuit. That's to keep the amperage low, so the tiny wires won't overheat. It's just according to the formula W = V x A: You can increase the wattage by increasing the amperage (heating up the wires) or by increasing the voltage (keeping the wires cool).
That's the reason why many countries don't use 110 V but 230 V - to decrease the burden on the electricity lines as you can then safely transfer more watts through the same lines. It's a kind of safety measure.

No. Fast charging does not reach the safety limits defined for our battery.

Yes. Just imagine it this way: If you fill your car at the fuel station slowly or fast - does that show any effect on your car's range ? - No.

If you enabled that in the settings, yes. Otherwise: No.
One question is missing: "Does Fast charge harm my battery if charging under hot climate conditions?"
Answer: No. There are temperature sensors in the battery, decreasing or even stopping the charge if the temperature gets too high.
Short: The difference between slow and fast charging is - slow charging charges slow. And that's it.

So why isn't fast charge always enabled? Why are we given the slow charge option?

To be honest: You already answered your own question - by asking your questions.
If you have a look around XDA, you'll find countless threads discussing the "problem" - many users fear Fast charging may harm their battery.
Some users even believe the battery would be charged with an overvoltage (as that voltage is mentioned on the rating plate of the charger), thus causing damage.
No, not true. That higher voltage is just used for safely "transporting" the charge through the wires by keeping the amperage low. After that, the charging circuit will regulate voltage and amperage down to healthy levels prior to reaching the battery.
But people get misled by many self-proclaimed "experts" (which will surely show up here, too) praying that Fast charge is a work of evil; just wait.
That's why Samsung made that feature an option, not a rule. A courtesy for the overcautious.

Hi again,
Let me ask you one last question.
I need to buy a new battery because I never make it home with charge. Is there anything that I have to keep in mind? Is it OK if I use fast charge with a generic battery?
Thanks

I'd stick with the original Samsung batteries. They had problems in the past (deforming, bulging S4 batteries losing almost all of their capacity - I had one of those myself, got exchanged for free), but I guess they solved the problem.
Reason is: Li-Ion batteries may have different charging parameters; like maximum allowable current.
The Fast charger was made specifically for the Note 4s battery. If you buy a different type, the fast charging current may exceed the current rating of a third party battery, leading to highly unwanted effects including destruction of the battery.
This is not too likely because each battery has (or should have) a built-in charging circuit for limiting the current, which even switches off charging if the battery's temperature reaches unhealthy levels. But it's still possible, depending on the battery type and manufacturer. I wouldn't place any high bets on charging circuits of cheap batteries; everything's possible.
That's why it's best to stick with original batteries - at least in this case.

If I were you I would stick with the Samsung battery, they don't cost that much and they come with their own charger and holder. It may cost a little more but you get a full warranty with it.
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.
Tons of articles on the net discussing this!

Yeah I've read some, but they are a bit inconclusive. That's why I started this topic.
Edit: thanks for your reply btw!
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.
Using Current Monitor, could you guys tell me what it reads for Max USB Current when you plug your A7's into stock or any QC charger? Or if there is a better app to see if it's indeed the board thats partly blown, despite that being clear since quick charging just doesn't work at all anymore and even PC doesn't want to recognize A7 once in a while.

About 3 amps? It always reports 2500-3000 mAh. I'm telling you this by memory, i didn't go and test that
this is my phone with the stock charger.
Got Accubattery as well to see and.... ~0.23-0.45A from laptop, wall, or anything at 37% when it would otherwise 3A it.
Hopefully new boards from Ali Express remedy this and maybe i'll try to see what burned out in the original one once I replace.
So, turned out to be bad cables that I've only got to test a little earlier w/ same chargers. Pheeeeeew!!! Changed my Ali order to still get 1 spare usb board and a battery for far, far less than rush shipping just 2 boards.
No ****, I've only ever seen 1500mah. Wonder what problem I've got? Going from stock charger.

The AEX lockscreen says 1500mah while accubattery has a high of 2200mah at 43% battery.
Lockscreen always says 1500 from my outlet though. From a computer it only says 500mah

Good to know.
I find it odd my battery drains 30% on my drive to work, and then while at work it loses about 10% over 8 hours. I installed accubattery so maybe I'll find the culprit. I usually don't use maps on my way to work.
Well, don't mean to hijack a thread.
So guys, i was reading some post here talking about the bests external/portable batteries for the Galaxy S8. I think it's not easy, because we need to consider the fast charg, USB-C, wireless charging, battery, that does not prejudice the health of phone's battery, etc. So, it's possible make a list of the really best Portable/External Batteries ??
Sorry my bad english.

I use my Streamlight lantern It has a 2 amp charge at 5 volt and 10,000 Mah battery i think
If I ever need a battery,I make it through the day no issues on my stock rooted setup with about 35% left normally....
I have one of the choetech charging cords that show a amperage draw while charging And the lantern puts off about the same amperage as my official chargers fast or regular
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.
