How do you know if fast dormancy is working, or rather is disabled properly, on Android? (or perhaps the opposite, ensuring it's enabled).

Does it have anything to do with data dropping from H to 3G? This shows as network type HSDPA:9 then dropping to UMTS:3.

How do you ensure its disabled, when it seems different for each device? Samsung seems to have their own way of toggling it. As does LG, per carrier in a sqlite database. But that doesn't exist on my Nexus 4.

So I tried a build.prop edit:
ro.ril.fast.dormancy.rule=0
But I'm not sure if this does it.

Anyone know?

Have been wondering exactly this myself, it seems to be quite different between various devices.

For such an important (seemingly) setting in terms of getting the most out of your battery it does seem to be glossed over a bit, particularly with imported devices.

Would be really keen to learn a bit more about this.

Network type simply indicates the cell state the device is it - it'll use HSPA resources when required and them hand back to the rel99 network when data resources aren't required.

Right. Thought that might not be it.
My HTC desire never dropped to UMTS, it has only ever been on H permanently no matter what rom I used.
The Nexus 4 has started dropping to 3g when idle so it's new to me.

Why don't you have the Nexus 4 yet?! I thought you would be among one of the first people to get it.

 

Regardless, I would love to know how to disable it on the Nexus 4, shall we start up a donation system to get Lokhor a Nexus?

Telecom XT is the only network that we know of that 'need' fast dormancy disabled.

I have galaxy note, disabling or enabling the fast dormancy did not really help the battery life. In fact, if anything battery life is slightly worse when disabled.

With my S2 if there was any difference it was within a normal margin of error for my daily use. I gave up disabling it a while ago.

I don't think fast dormancy is an issue with the Nexus 4

There's no wakelock associated with it that I've seen

Interesting. With my Samsung devices I've found a significant increase in battery life with FD disabled (Captivate, S2 and S3). I guess results may vary depending on how much you use the mobile data connection.

I think I have a similar issue RE switching to between 3g & H, continuously on a HTC One V. I take it disabling Fast Dormancy differs by hardware manufacturer, I have not seen much from HTC. Weird thing, my phone is from Telecom NZ with the issue, my wife has the exact same phone parallel imported, no switching from 3g to Have & battery lasts way longer.
Does anyone have any tips for enabling/disabling FD on HTC or at least just checking the state?

Cheers

I would prefer to turn it off even if there is a minor battery life increase. But I suppose I won't know till I can try it.

A phone is supposed to switch between H and 3. This is exactly how state transition changes occur as HSPA data resources are allocated and released by the network.
