According to Hunger Meter, average consumption is about 800mw, enough to drain full battery in about 8-10 hours. It looks like CPU never goes to the low power mode.

Can not confirm on my Jolla 1. Here's everything fine after the 2.1.4.14 upgrade.

Hmmm, I also have Jolla1 but have noticed how quickly the battery is draining with 2.1.4.14, either that or all 5 of my batteries are failing at roughly the same rate. I need to test. It does seem that the battery goes really quickly the closer it gets to being empty, like the last 10% is done very quickly.

@Edz sounds a bit like battery decay to me. (BTW: Friday!!!)

@lakutalo - agreed - but on all 5 batteries?, ahh, who cares, nothing lasts forever anyway and in 2 weeks time, I'm heading 1200 miles south for the rest of my life! ;)

@Edz lucky you, as it makes it most likely for your batteries to gain in stamina again, due to the highly probable rise in expected average temperature. (Didn't want to give a Susskind-like lecture on electrodynamics, but still had to make the answer as nerdy as possible.) 8)

Hi @azupan, there are a couple of posts similar to yours, as the described behaviour is quite common after SFOS updates. In most cases your phone has got some background tasks running, such as tracker. Most likely you'd just give it about a day or so, and it will come back to normal again. Cheers!

I've noticed this behaviour as well, but this time it had been going on for days.

The first day it was like you have just said. But now everything works out nicely. And yes, I am on 2.1.4.14 with J1. So let's hope the best! ;)

@lakutalo

Do you have SD card in your phone? I have 64GB SD card. Could this be the reason why return to normal takes so long?

azupan ( 2018-03-16 14:57:01 +0200 )edit

Yes, but mine is only 32GB. It could well be the bigger size, but it depends on what is stored on it.

I've bought new 64G SD card, but I haven't figured out how to format the bloody thing properly. If I format it under OpenSuse Linux, it works OK under OpenSuse but not under Sailfish OS. Unfortunately, I forgot how I managed to format it the 1st time.

Anyway, while searching for info, I came across this:

While it took BTRFS some time to mature, since Linux kernel 3.4 it can be regarded as "production ready" (as the Jolla 1 phone shows). It has been designed with FLASH-based mass storage in mind, but has a couple of drawbacks, e.g. free space management (when over 85% full), performance on specific operations, being compute- and memory-intensive (especially when over 85% full), occasional "btrfs-balancer" runs are recommended for optimal space use and performance etc. OTOH BTRFS can provide transparent file compression, subvolumes etc.

I guess this pretty much answers my question. My former SD card was indeed 80% full. It's either this, or SD malfunction or both.

In any event, the consumption is back to normal, problem is solved, and I won't investigate this any further.

The easiest is to format it either in ext4 or in vfat if you want to read it on Windows.

I've formatted my new SD card with EXT4 instead of BTRFS as advised. Everything works fine now, power consumption is even lower than before, or so it seems.

Thanxx :)
