Last week I was in a summer cottage without electricity, to prepare the life there I carried on with 2 power banks (one w/ solar panel to get extra 10% per day), and car adapter was 20 minutes away, should I have needed it.

I had my SailfishX (Mouhijoki) device on all the time, on cellular network, android services running (so I could receive those ~5 messages per day), and often I had forgotten an ssh connection open (where remote sshd endpoint had ClientAliveInterval set to 240) for hours (overnight and so on).

In addition to that I did some minor web browsing and map viewings, probably accounting 10-20 % of the battery life.

For days I did not have to charge my device at all. The power banks (and the solar extras) were mostly drained to mobile devices of others.

To my estimate (now that I've written the above) is that 2 full charges was enough to keep my device running for a whole week (and I was left around 20% of battery at the end).

I think that is pretty good. I remember plugging my phone to charger often when outlets are available (just to be sure there is power available for potential heavy usage all the time).

Sounds about right. For me the usual recharge time is 4-5 days on (mine) normal usage. OTOH in recent days when travelling roaming + data connection sharing with heavy client data usage almost drained battery before the end of a second day. Luckily we had a power bank.

Strange, its good when idle, but with normal usage i have to charge it every evening.

I used my Xperia X Compact for a while and set up the original Xperia X (Mouhijoki) on the table with a separate SIM (in 3g mode with adequate coverage of 2 to 3 bars). No other use than hourly sync of emails, contacts and calendar (imap, carddav, caldav, sync off by night). Android was turned on, but I didn't have anything that would require constant online such as Whatsapp or XMPP.

After three days Battery Log application showed that it would have lasted at least for 2 weeks. The line was basically flat. Deep sleep mode seems to be very effective and on unless constant online access is required.

With my normal usage Xperia X lasts for 2 to 4 days.

I was in a trip few days ago, and I noticed that in 12 hours, with a call 3 - 4 mins, checking the weather / sea conditions with an android app twice, the battery went from 75% to 70% ! I was very happy about it, also since I didn't have very good signal in all these 12 hours.
