Pretty much a lurker here, but for once I have to post. Been searching the forums, for other devices as well, and not been able to find any particular info that solves a problem I'm having. Thought it could possibly be kernel related. Before I start, thanks a lot to AndreiLux for all your work!

Problem is, with wifi on, battery drain at idle is huge. A few % per hour usually, so I get maybe 24h of use out of the phone before it needs a charge. Switch wifi off and move to mobile data, and all the wakelocks present in betterbatterystats disappear. Phone will happily sit idle for 2 days or more.

So the context for this, and what I've done to try and solve it:

Full wipe and update to latest kernels/firmware versions - this made no difference so I simply restored my backup, hence the older kernel version listed as running on my device below.

I'm not a heavy data user, all the stuff like google location data, maps, is off.

Gemini app manager has the autostarts for various "problem" apps like facebook disabled.

The wifi is using a fixed IP both on the router and the phone.

Anything doing background syncing is currently off for testing (but this has made no difference to battery life so far, anything that syncs only syncs once per day normally as well)

The wifi is set to turn off when the phone is asleep.

The only thing I can think of that might be keeping the phone awake is packets on the network - though I have no idea how to diagnose that, if anybody does, a link in the right direction would be very helpful.

The wakelocks present are wlan_rx_wake, and l2_hsic. They ONLY appear enough to cause battery issues when the wifi is switched on.

Phone (i9300) is running:

4.1.2 - Vikingway 2.2

Baseband XXELKC

Kernel Perseus alpha 31

Of course no idea if this IS a kernel issue, but this seemed the best place to post this.

Thanks.

Use Greenify and Startup Manager, both from the Play Store. Your problems will probably go away. If not, check my thread in the General section to maximize battery life and performance.

Re: [Kernel][27/03] Perseus

Andrei already added Zcache to his "testing" kernel but it was disabled because it was creating conflict with Samsung implementation of Zram.. Search a few pages back and all the discussion he had with Yankk
[Galaxy S III Original Android Development] eyalpaz:
tried everything you and others said.. Still not working. And I think it's not rom related cause it didn't work also in v43
[Galaxy S III Original Android Development] AndreiLux:
I didn't say it was caused be ZRAM, I didn't identify the problem but I gather it has to do with Samsung's CMA changes and some memory alterations that are currently in the kernel.

Hi! Hope someone can give me some advice...

I was running UltimaROM v11 with perseus kernel alpha34.3.

I had some problems with lag time tot time. But now my phone shutted down itself. And now it won't go further than the bootanimation.

I tried wiping cache and dalvik. But still. Now 15 minutes on bootanimation

What can I try to not lose anything but still fix this. Please hope someone in this thread can help me?

Same here. It's a pity since it's my favourite kernel but having to reboot two or three times, to at least wipe cache, and so on its quite bothering...

I think I'll move to another less battery efficient and feature packed kernel until that problem is resolved.

I also noticed that from time to time there's a problem that limits antutu to half the usual results, and makes the phone freeze or crawl at times....

If AndreiLux thinks he's lost his mind already and he has to go and make crazy pictures now he has a lot to learn.

Personally I think it's a good effort. Not too over the top, definitely enough there to make us scratch our heads and wonder what is going on. It's a strong performance and I think there's really a strong future there for this young competitor.

Unfortunately everything he's saying is probably true as well, but that's a long discussion.

Sill struggling with those boot loops problems... Reflashed the kernel a number of times, tried different things, to no avail. It really seems that ever since v34 (maybe a bit before, even), there's a problem between my phone and this kernel.

I really hate that since I have no problems whatsoever with booting or lags or anything with the "replacement" kernel I use (Boeffla 2.9) but it's far less configurable and eats battery twice as fast as Perseus...

I start to believe that I'll have to search on my hard drives for older perseus version...

Re: [Kernel][27/03][GPL][CPU/GPU/MEM/INT OC/UV][CHARGE][OPTIMIZED++][CALIBRATED] Pers

It's about time Andrei stepped up marketing for Perseus. I hadn't known about this kernel for the longest time since it was quietly buried in the original development section. That was one of the reasons I made a thread in the General section, to direct them over here.

Believe me, Andrei isn't one who believes in making money off his kernel. I had suggested creating a paid app like Franco does for the Nexus 4. Franco's app is a piece of crap compared to Perseus but he makes $5 off each user and they view him as God over there. Andrei told me that he couldn't, in good conscience, charge users for his work. Furthermore, Andrei couldn't even bring himself to ask for donations until now. Imagine if we all donated a couple bucks as a thank you. He certainly deserves it more than Franco.

I'll be the first to donate. If you guys can spare 5 or 10 bucks, I ask you to donate also. After all, we spend countless dollars on apps and games, but the kernel is the most important component of our phone.
[Galaxy S III Original Android Development] AndreiLux:
Well enough of the fun now. I see moderation doesn't have the balls to stand up to a idiotic "nudity" report towards an ancient Greek depiction of Perseus. I wonder what these stupid people would do if they would actually be put into the streets of Rome or Athens :rolleyes:

Anyway, good to see who prevailed in common sense and who failed... the whole thing was a jab at the prejudice of the "XDA 1337 dev".

To anybody having bootloops from Boeffla kernel: Clear your init.d scripts before flashing Perseus. He's installing some scripts which screw up booting here.
[Galaxy S III Original Android Development] zykic:
Maybe you got the bootloop with init.d Boeffla created?
[Galaxy S III Original Android Development] metinrecepi:
This is the greatest version of Perseus that I've ever used, great results.

It may be that the read buffers are too high at 2048. Try cfq at 512 and 1024 and see if the lag still remains.

Hi Andrei, when you have time could you please look into the issue that many of us are having with mic not being able to record sounds? It doesn't seem to be ROM related, many of us are using different ROMs (and it worked fine with kernels before the boeffla implementation, so I'm assuming it has something to do with it). Regular phone calls work fine, it's only an issue when using apps suck as Skype or Viber, or when straight-up recording audio. Thanks!
