Is it bad to constantly top off your battery?

[Nitemare3219]

TOO MANY MISCONCEPTIONS. Let me clear them up !!!!

2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v

You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.

Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.

I might put this in a new thread.

4.35-4.4V? You just discredited everything you said. 4.2V is the typical fully charged voltage for a lithium battery.

You don't need to avoid **** unless you keep this phone forever. You're just hindering your user experience. Don't put it in a new thread, because we don't need this crap spread.

I'm an engineer but people prefer links so rather than do a lot of typing I'm including one that offers a decent overview of lithium ion batteries and the fundamentals of their very specific charging... http://www.digikey.com/en/articles/techzone/2012/sep/a-designers-guide-to-lithium-battery-charging

I would also recommend perusing some of the literature on how quick charging works, it is a tightly controlled process that requires embedded circuitry on both ends along with its associated logic. It may be you walk away from your reading having lost your concerns about it.

And you just made yourself look like a fool.

1) Note 7 uses a high voltage Lipo battery. Nominal voltage is 3.85 instead of 3.7v. Full voltage is around 4.4v instead of 4.2c

These are often called Li-HV in the RC hobby world.

2) I am NOT hindering my user experience.... I disable stuff I don't use because I don't use it..... With power saver I have zero slowdown thanks to Nova Launcher + Google Keyboard. I even used EZ Disabled just today and it works flawlessly and my note 7 feels butter smooth.

3) I DO plan on keeping this phone forever as with all my other phones because they get handed down to family members who are not tech savvy.

The "crap" in my post is about all the tips I can think of to prolong battery longevity. Don't like it ? Don't use the tips. Go educate yourself before spewing nonsense and false accusations.

I have since the old brick phone days always let mine get down to 15 - 20% then charge till above 90%. Once around about a month I let the phone drain all the way and charge all the way. Never had battery issues or had to replace one. My other half gets a new phone leaves it on charge overnight and uses it. She ends up with battery problems and even replacing them.

Samsung a while back actually said with their tablets you should never run them to 0% as if they got that touch too far they would never charge again, so really you should avoid going to 0% as every time you do you are taking a gamble on if the phone will actually see the battery as viable to charge as if the voltage drops just slightly too far it recognises the battery as damaged.

I guess like most people leave my phone on charge overnight. Is there any way to have it automatically switch off once the battery reaches 90%?

Unplug it. Failing that buy one of those plug in timers and set the time to charge accordingly.

Unplugging it while I'm asleep isn't going to fly but yeah - a plug in timer might work.
Was hoping for a software solution but can't find anything sufficiently automated.

batteries got a mechanism to stop charging current when the internal cell of the battery is at its max voltage (as explained by THS1989), so keeping the device plugged to the charger has no effect on the battery directly, in the other hand the device is consuming some power to stay connected to the network, also if WI FI, NFC is enabled, so battery voltage will slightly drop, and since it is connected to the charger, it will keep compensating this drop by charging, even if it is showing 100% on the screen, so actually what Nitemare3219 said about high stress is also correct.
SAMSUNG's embedded battery models also register how many cycles you are a=charging the battery, and that affect life span of the battery, so less cycles mean longer life span, that can be achieved by keeping charging percentage between 20-80%.
fast charging and wireless charging is also not so good for the battery, and could cause a shorter lifetime.
best thing is to be moderate in charging/ discharging the battery don't be aggressive in power consumption (gaming with high brightness as THS1989 mentioned), also using regular chargers could expand the lifetime of your battery and lower heat dissipation from the device which might cause serious issues on the long term.

Gents... When you see 100% that is not at full charge and when your phone shuts down on low battery it is not depleted. In the case of 100% that is maximum OPTIMAL charge and depleted is MINIMUM allowed charge. Where that occurs is controlled in the kernal specifically with goal of reducing capacity loss. Nor does the battery charge continuously overnight. The battery voltage must drop enough to reach a set point before it begins a tendering charge which occurs at .1 amps on QC chargers and is not counted as a charge cycle by the kernal which is also controlling that aspect of charging. Modern phones with quick charge tech use a very tightly controlled charge regimen that is quite sophisticated. Again, I highly recommend browsing the literature I suggested.
