Should be OK. The phone will regulate how much power go into it, if external power source can provide more than that.

Well, you can check which component/app is draining the battery under General > Usage > Battery Usage.

Can also try to get those system utility to check CPU utilization pattern of running process.

You can check cellular usage under the Settings > Cellular. WIFI I guess check from your router.

Shouldn't matter I guess? As long as it's unlocked from carriers

Check the Photo settings. I think you have photo stream to iCloud enabled.

Could be. I am checking mine too. Too much background sync everywhere. iCloud and iCloud Drive is separately set zzz...

Hmm. Why Settings app is using cellular data?! 1/2 of my data consumption came from there duh.

I had that turned off before I switch to cellular.

Batt usage. Again Settings show up.. And with note of background activity.

Charge cycle is not number of charge. It's number of full charge. E.g. you charge at 50% to 100% twice, that's 1 charge cycle.

And believe it or not, deep discharge has more damage than shallow charge.
You should only drain battery to 0% for re-calibration purpose.

It simply means you can just charge whenever you feel like doing it. In fact it's better to do frequent smaller charge than to drain battery flat and charge to full.

You don't need to re-calibrate really. It's just to let the phone to be able to estimate battery more accurately. To do that just use until battery flat and charge to full again. Few months once would be sufficient.

I used it that way with my iP4 over like 3 and half years, battery life didn't drop much compare to when I first used the phone.

All of them.
