As I wrote, in certain conditions (usually at nights and on weekends) power consumption on 4G drops to 110-130 mA, and then further lowers to 30-60 mA when the device is idle and the display turns off, which doesn’t really differ much from 2G power consumption. And it can stay so for hours. Then it suddenly goes back to 200-300 mA and remains so even when display is turned off. And it can take hours before it again drops to low levels, eating battery like crazy. There are no active processes with any increased CPU usage, so it must be the radio part eating that energy.
Anyway, it’s really difficult to tell what’s causing it. Maybe even without the actual cell/band switching taking place, in certain conditions (maybe depending on momentary signal strength or quality, or current mobile network “load” - quantity of subscribers momentarily using that specific cell/band vs. its capacity) a lot of “talking” between the phone and the network is taking place and prevents the phone (at least its baseband/modem part) from idling and reducing power consumption. Such explanation would actually correspond with the times at which I usually see lower power consumption (mostly at nights), i.e. periods of time when there’s a much lower mobile network load (less active subscribers, less traffic), less interferences, etc.
Had same problems as others here, but it turned out half of it is my SIM card. I used SIM from our local virtual operator, it uses what is called “domestic roaming”, i.e. constantly switches networks.
With that SIM I had 1% drain every hour (with 100-150 mA), but when I put “ordinary” SIM (from operator with its own network), it started discharge slower, only 0.6% in an hour. And by the way, roaming is still enabled. So now it’s more or less acceptable
Hello to everyone who has been reporting on this thread, as well as analyzing and speculating for the cause for battery drain issues. It is a good starting point for us as with this information we can possibly narrow down the causes. Or make some smaller improvements to identified areas.
So, we are now following this internally and maybe after 4.6.0 is released we can start looking on this issue more closely.
I’m glad that the problem is tackled and sauna brought very good things too like faster gps fix and i have the feeling adding songs to a playlist is also much faster now.
Well, too bad that this is not the developers decision. I bet the developers told the managers quite early that they should focus on eventually getting the basic functionalities out of beta state. My post is addressing the captain, not the crew. This thread is almost two years old by now.
i have an xperia x compact for holidays and i’m still baffled how much more uptime it gets than a 10 ii or 10 iii, i gues with aosp from sony it’s a hit and miss. i started a download of some GBs of size before going to sleep with 23% and in the morning it had about 17%. a 10 ii would have a drained battery by then. also the current of the xperia x compact is 25mA at idle and of the 10ii it is always around 100mA. the xperia x compact is really a nice phone, it even has better battery life with sfos than with android.
Actually, the percentage value isn’t too reliable as it isn’t linear (it tends to decrease at different pace depending on battery charge level). It is much more reliable to check with e.g. Battery Buddy’s log the actual power consumption in mA.
As you can see e.g. in this post, while people get ~ 1% per hour readouts based on the battery level indicator, the actual power consumption they have at that time is on average 100-150 mA, which in case of a 4500 mAh battery is actually 2-3%. To get 1%/h, the average power consumption during that time would need to be 45 mA.
When i install from android to sailfish newly after few android months, let the phone just on the table.
It lasted 3 days. I was shocked because before it was 1 day. Now with 2 emails, weather with event view, 2 Nextcloud, some phone last the same.
No drainage. Echo i haven’t noticed. I’m happy with it.
My 10 iii has a typical power consumption of 150 - 250 mA in basal state with WLAN and 4G mobile. When using GPS or similar it goes up to 500 - 900 mA. Fresh flashed 4.6.0.13. It’s never below 120 mA.
Seems like an application is preventing the phone ftom going to sleep, you should check the cpu consumption of your running applications. Maybe an app has crashed.
