Hi.
These days your devices come with power adapters that can take either 110 or 220 Volts.
I have used my devices mostly in 110 V outlets but also for short terms (close to a month) in 220 V, with no problems.
Now that I've been staying in Argentina for over 3 months, I've started to notice certaing degradation in their battery capacity.
I see that both my cell phone and my tablet battery capacity is a little lower.
Also my laptop has started to make an unusual noise, while using the power adapter, that I can notice when using headphones. And when plugging the power adapter, the laptop does not take charge. It only works if I turn it off and then plug it in.
Some devices can be affected by temperature (we are facing the winter, with 12°C, which I don't think is that cold).
Could it be a problem with the outlet?
If so, what should I check?
Here both the European and Australian outlet connectors are used. Is any of those more trustful/stable in terms of power?

I appreciate your help.

 

The Input-Voltage is practically irrelevant with these "Multi-Voltage-Devices".
The Input-Voltage will have no effect on the "Internally-Regulated-Voltages",
until the Voltage drops below around ~90-Volts.

Could the frequency affect it too (110 V- 60 Hz Vs 220 V- 50 Hz)?

 

Nope ......

The thing about lithium-ion batteries is that if you charge them to 100% regularly, they will last about 2-3 years and will suddenly fail hard. However, if you charge that same battery to 90% each time and disconnect it before it reaches 100%, you just multiplied that life span by 4! Drop another 10% and a similar improvement is realized. This makes me wonder if that extra mains voltage, aside from the fact the converter should be compensating for that, is charging a little bit.... better/faster effectively putting it at 100% for a longer duration? Once the battery is done, you cannot reverse the damage (AFAIK). Best advice I can give, don't let things charge completely. The days of NiCd charging logic are long past.

 

The output of the charger is a regulated 5V. The phone knows nothing about the input voltage to the charger.

With lithuim batteries, its a current thing, not a voltage thing (sort of)... You can regulate the voltage all you want, it will take the current that is available (and todays chargers are dumb in that respect). Ask google how motorola made their 17-minute turbocharging work (very well I might add based on my moto one 5g). To that end, 5v will be changing soon as the current is limited mainly by one thing, the contacts in the usb adapter. Motorola did the impossible by pushing 4A thru that connector, it wont get any better than that (or will it????) Thats why the new scheme (that you likely haven't heard about yet) will involve a variable AC voltage. They will start out with the standard 5v, do a data handshake to make sure its compatible, then switch to about 70vAC so that the same (or much more) power can be pushed through the connector with a fraction of the current. Just wait 10 more years lol...
