Question S22 battery conundrum

[John Speed]

I only send a few of messages per day and usually the battery lasts 2 days max. Last year I went to Paxos (Greek island). The battery life jumped to 4 days ! On return to Uk it was back to 2 days. This year same again 2 days Uk but 4 days on Paxos. The same happened with my wife’s phone so it is not unique to my phone.
I have searched the internet but not found any clues as to why. Does anyone know what is causing this effect. Would love for 4 days in the Uk.

Welcome to Android Central! What's your cell signal like where you typically are in the UK? If your cell signal is mediocre at home, and if it was very good on Paxos, that might at least partially explain the difference.

Also, do you have any idea what your screen time was in both locations? Maybe you were using your phones less while on vacation (unless of course you were taking lots of photos or using them to navigate a lot).

Hi B Diddy, thanks for your reply.
The cell signal at home is mediocre and a little better in Paxos. However , both at home and in a Villa on Paxos Wi-Fi calling is in first choice so I would expect signal is less important. My wife’s phone also performs in almost identical way. I could understand a small difference between the two locations but a 50 % plus improvement in Greece seems odd. We both rarely use audio calls and generally just a few messages per day . For the majority of the day our phones are on standby In both locations but even on standby the overnight loss of battery capacity is significantly less in Paxos..

Poor cell signal can still impact battery life, even with wi-fi calling on, but I agree that it would still be a stretch to attribute that big a difference to the signal.

Do you do a lot of smarthome stuff while at home?

Interesting point. We very rarely use any smart features preferring to use a iPad for those facilities. We are old fashioned and just use our phones for messaging, and not many of those.
I think something is going on in the background but I can’t trace what. Strange that it does not seem to occur in Greece.

If you want to check your signal strength in dBm, then have a look at this link from Samsung. https://www.samsung.com/ae/support/mobile-devices/smart-phone-how-to-check-signal-strength/

Obviously you can't tell what it is in Greece unless you go there again, but you'll be able to see what it is at home.

Thanks Laura and B. Diddy,
Very useful link. In House the signal is poor so Wi-Fi calling is preferred and works well. External network signaI is adequate for a rural location. Will have to wait for next year to test Greece. (Good excuse to go again).
My thoughts turn to the network providers. Could there be some background communication going on in the Uk that is not present on the Greek networks?

Welcome to AC!
Another thing to consider is your using a US phone that works with US bands more efficient so I wouldn't expect between countries to be best with cell and battery.

 

[John Speed]

A good point. However, 2 days capacity in the Uk and 4 days in Greece is a significantly big difference. What do most people get out of a fully charged Sam S22 in the UK.?

Not getting too deep into this, it sounds like you've reached a conclusion, but could it have also been that you just weren't using it as much being in such an destination?

 

[John Speed]

Hi Vidjunky,
Surprisingly it’s the other way round I tend to send more photos when on holiday than the odd one at home.
So it’s still a mystery.

It could be that UK has bands closer to US standards than Greece, it's not surprisingly to get better battery or cell phone reception from country to country but you're really not using a device from those regions.

Thanks to all who have replied to my querie. I have scoured the internet and no one seems to have experienced the same problem.
So for the moment thanks again and if I do find an answer or method to trace the cause I will post it here.
