Will a 5.2V 2.4A power brick overcharge the phone?

[DanRomania]

I have been using my Beats Pill Plus power brick and a SuperTouch MicroUSB cable to charge my mobile phones for quite a while.
I wanted to know if there is any chance of damaging the battery life of the Note7 by using the same combo (the original USB Type-C cable with the Beats power brick)
The output of the power brick is 5.2V, 2.4A.

If regular charging is at 5V and 2A, then yes, you are slightly over charging and compromising the longevity of the battery.

The devices I have charged with this combo also tend to get slightly warmer when using the phone while charging

That also puts extra pressure on the battery and reduces longevity. The worst thing you could do is charge your phone at higher voltage and amps and at the same time, play a graphic intense game.

If you plan to keep a phone for a long time, charging at a lower amp (but same voltage) is the best.

I have the S5. Generally, it is not recommended to charge overnight. I tend to as I can obviously replace my battery. But when I do that, I don't use the standard 2A charger. I use a Sony charger from a camera that charges at just 0.5A - 4 times slower charge.

Well, I guess the best choice is to use the charger provided by the producer of the phone or a high quality aftermarket one with the same specs?
And yes I do plan to keep my phone for one year or two.

I have read that the phone actually uses the charger as the main power source and puts the battery on stand-by when it's fully charged so leaving the phone all night with the charger plugged shouldn't be an issue

Definitely! You can under charge (as in amps) but don't over charge. Also, don't let your phone always go to 100 percent charge. To really make the battery last, stop it just a tad before that.

And the most important. Regularly recharge. Try to avoid letting the battery go lower than 60 percent. Lithium ion batteries love regular smaller recharges.

Not correct. The battery absolutely full is at a high state of stress. Keeping it in this state for an extended period worsens the situation.

Well, it makes sense I guess.
To sum up:
- use the original charger provides with the phone
- don't let the battery die or go below 30-40%
- don't charge it till' it hits 100%
- don't let it charge overnight

Now, would it be bad to fast-charge it before going to sleep so that I wouldn't have to charge it over night and still have plenty of juice in the morning?

Sorry to be the guy raining on your parade, but fast charging and wireless charging are battery killers. Fast charging charges at a high over amp rate, and then tapers off. Wireless charging heats up the battery much more than regular charging.

Use both very sparingly or not at all.

So, use fast-charge only when needed. I do not plan to buy a wireless charger as I see no advantages over the classic usb cable.

If you are about to go to sleep and your phone is at say 40%, why don't you put it on your regular charger but with a timer attached. If it takes 90 mins for the regular charger to charge from 0 to 100%, then set a timer for 30 mins or something like that. In the morning you will be somewhere in the 90% range and you won't have had your phone all night on charge. Even better, get something like a Belkin smart switch.

I myself keep my phones for longer than 2 years so I understand you wanting to preserve your battery. I have the S5 so I don't always follow the suggestions I am telling you.

But I can guarantee that with my next sealed battery phone, I will be following everything I am saying and stop overnight charging.

I never took into cosideration these smart switches, I am browsing the local web stores right now for something like that
