6 Plus Battery Question

First, read this:

My experience and opinions:

It is perfectly fine to charge it to 100% and keep it plugged in at 100% for a "normal" amount of time (e.g. overnight) ... it will not overcharge.

Letting it drain to 15-20% is not a problem, but don't let it drain much further on a regular basis.

When it is new the battery may drain faster than normal -- usually because you're fiddling with your new toy more than usual, but there may be some settling in time (debatable on that point).

Occasionally iOS updates can cause unusual battery drain, but a restore (backup, erase and reload backup) normally cures that. Other than that, use Airplane mode if you're in a poor or non-existent cellular region if you don't have external power available.

The 6+ has awesome battery life, better than any prior iPhone I've owned. Enjoy it.

Is it bad to plug it in for like an hour, then unplug it to go out, then come back home and re-plug it back in and let it charge to 100% or what?

No problem at all, lithium ion batteries don't have "memory" so there is zero harm in a partial charge.

Hi there,

Congrats on your new phone! I love my 6 Plus. It's the best phone I've ever owned. That being said, I can tell you that its likely that the way you're charging your phone isn't the problem. Depending on how you use your phone, there can be many reasons why the battery doesn't seem to be lasting as long as you expect.

There are some features, like Background App Refresh and Notifications that can use up a lot of your battery life. Every time your display 'wakes' for a notification, it takes a certain amount of power to wake the screen. Auto-Brightness is another huge thing that impacts your battery life, as well as location services.

You will find some great tips on optimizing your phone so that its as efficient as possible. It also talks about how iOS devices charge and how charge cycles work.

Hope this helps!

Of course, no problem. If it seems like it's draining more than it should be, you could try calling Apple or taking it into a store. They can run a diagnostic and see if the battery is showing as defective. If it is defective, it should be covered under the Limited Warranty.

Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.

Use the wall-mount charger that came with the iPhone and charge overnight. Do NOT use a computer's USB port. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the procedure necessary to calibrate the battery level meter.

I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know. If the above test does, in fact, indicate a problem, read this.

Also, according to Apple:

Use Your Device Regularly

For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.
