[Q] [Siyah 2.6.7] Kernel Wakelock - Galaxy S II Q&A, Help & Troubleshooting

Can anyone enlighten me as to how svnet kernel wakelock drains my battery.
Lost 20% overnight, BBS shows 90% phone awake during that period mostly due to svnet.
I have JD ultimate set up, so shouldnt be running sync all night long tbh

JD uses more battery than it saves, it could be causing something to try to sync, but as its unable to it keeps the phone awake.
Try posting the dump or SS's of the BBS screen.
svnet means something is downloading, or trying to.
Try disabling JD.

That's a shame, I've bought the premium version of JD.
It should put the phone to sleep it between wifi syncs

What is should do and what it does are worlds apart, it sounds great but mostly it causes worse battery drains.
Lots of apps are not great, and when they try to sync, they will keep bloody well trying until they manage to, mindless of the battery drain.
And with the standard sleep policy on wifi, wifi will turn itself on and off when needed, also the new wifi chipsets are not like the old ones, there idle drain is almost non existent.
Just try to keep the phone in deep sleep as much as you can (Good to see you using betterbatterstats) and you will be fine.

I will disable JD this night and compare,
Too bad I can't get a refund for JD anymore, such a shame

Market refund window sucks, shame its not still 24h, you could always email them and ask for a refund and it doesn't do what it says it does, depends if they have a longer money back policy, I know some devs do.
But your best bet is to wait and see first.
I only lost about 1-2% over a 10h night so its doable.

Its well posted that JD can cause battery drain though some users find it works .
Worth reading all the battery faq posts to learn better battery habits .

Agreed, but one can never be sure without trying
So basicly you think the wakelock is caused by JD trying to open connection to sync but never closing them, thus not putting the phone in deep sleep?

App tries to sync, JD has network turned off, app still wants to sync, keeps the phone awake trying to sync without a network connection.

Also having a huge problem with the kernel wake lock.. Lost 75% in 10 hours, with very little actual usage. Could it have to do with Toggle2g? Please help! Thanks

"wlan_rx_wake" is killing you. That's the WiFi drain bug. For me, Entropy figured out that part of the reason was due to my uVerse router spamming me with a multitude of ARP requests and thus my router was waking up my phone constantly when it should've been in deep sleep.
This happened when I was on UCKK6. I've since done a data wipe/factory reset and gone back to a UCKH7 baseband since UCKH7 seems to have teh filters working and the phone doesn't seem to respond to the uVerse router's spam.
Are you on UCKK6? If so, you might want to wipe and revert back to UCKH7.
Or if you have a uVerse router and want to keep UCKK6 (for whatever reason) - someone else here posted how to put a router behind the uVerse router. This way uVerse still handles all the IPTV stuff but the actuall wireless duties can be conducted by the 2ndary router which won't spam your phone to death.
If you search for it, you should be able to find the instructions on how to put the second router behind the uVerse router...again, assuming this is the issue you have.
Good luck.
