AC chargers give the message " phone is using more current than it can charge. However, USB charger plugged into AC adapter works fine.

Help AC charger drains battery

You need to define "a/c chargers" a bit more.
are you saying that the standard 2.1 amp a/c module using the OEM cable/equivalent is not able to charge the battery?
if that is the case, something is wrong with it.
I have a wireless charger installed inside the back of my phone, and that will only provide ~750 milliAmp of current to the battery. It is possible to have a lot of apps that require more power than that if the screen is bright and moving a lot... in this situation, the battery would indeed go down, not take a charge.
I have never seen the message you speak of.

Yes, a standard 5.0v 800 ma charger will cause the message and drain the battery very quickly. Even tried a new one with the same result. Also tried a car charger that didn't cause the message but also drained the battery. The only charger that will work is a USB cable plugged into an AC adapter. It works normally. I should also note that the phone no longer recognizes my MHL HDMI adapter at all. I've ordered a new battery and will test it when it arrives.
It's not about voltage, and it's not about a standard, and it's not about car or ac or USB.
It's about current.
Voltage is pushed by the charger but the phone / battery draws (pulls) current.
Your phone never runs off of the charger, it runs off of the battery at all times.
And it can charge the battery at the same time.
If and only if the current supplied by the charger is greater than what the battery is already supplying to the phone.
All you've learned is that 800 mA (0.8 A) is not enough.
Your "USB adapter charger" is the same as any "ac charger" - it converts 120 VAC to 5 VDC - and supplies a stated current.
Look at the usb charging module. By law, it lists its rated current supply.
I don't know the exact number, but I know from what you've said that it's greater than 0.8 A and by experience, I would guess that it's 1 A, or 2 A or more.
And that's why it charges when a 0.8 A charger won't.
Hope this helps.

First, thanks for the reply. I checked the adapter and it's output is 5V 1A. It only shows a mA on "input" which says 200mA. The "input" on the regular charger reads 0.2A.
To clear up any confusion, all other AC chargers worked fine until recently. What would cause the change? And what would cause the correlation between this and the HDMI adapter not connecting anymore?
The charger is a transformer that changes input power to output power at a different voltage and current, and then a circuit to change the ac to dc. So, you don't care about the input current. They tell you that by law, so you know how much juice you're using.
A 120 Watt light bulb uses about 1 A on your home power (for the USA), so 0.2 A is like burning about a 23 Watt bulb. But only when the phone charging light is not green.
It's possible that you have a hardware problem with your charging port and the HDMI problem is related.
It's also possible that the HDMI problem is coincidence and there's a problem with some sort of background process going screwy.
If you turn the phone off and the 0.8 A charges it in a fair time - not sure for your model - maybe a few hours? Then the hardware is OK and your software is wonky.
Check for what's eating power with GSam Battery Monitor, while it's not charging and the screen off - Check the graph after an hour or two and check other, turn to landscape for a clear picture.
It should not show much Active with the screen off.
Btw - if you're using any automatic task killers or ram cleaners, uninstall them yesterday. They flat out lie and actually drain power.

Btw - maybe I read the question with too much complication.
The little m stands for "milli" as in one one-thousandth.
1 A = 1000 mA
0.2 A = 200 mA
It's like milk.
I can say - this carton is a gallon of milk, or I can say, this carton is four quarts of milk, or this carton is 128 ounces of milk.
It's still the same amount just said differently.
