what is wifi driver ?
[LG Optimus 4X HD] Maczuga:
For now as I tested:

On smartmax - 3h of music, nothing else:

- 1h14m of deep sleep.

- 1h 15m of 204 MHz.

- baseband very very low.

Now I'm testing wheatley and Wi-Fi drivers (so far it looks like wlan_wake is less frequent, also signal quite stronger for me).

[LG Optimus 4X HD] dokii22:
Sorry for my ignorance,I didnt look second post and these drivers so I instantly asked about them,next time I'll check first page of every thread before I ask stupid question:

Just a quick question,I just flash these wifi drivers normal as kernel and thats all ?

Thanks guys and I apologize one more time :)
[LG Optimus 4X HD] AdiSimpson:
i have also no problems with deep sleep @ v2.51. v2.5 not tested.
[LG Optimus 4X HD] tonhao12:
Yes, just flash it the same way.

Now another question, if I flash another kernel after have flashed the wifi driver, will it override the wifi driver ?

Thanks in advance.

I'm running 2.51 and slimbean 7 8. About the battery life, on standby, it's not bad, but it is not as good as before, 3 hours of standy and 4% baytery drop. Slightly above 1% per hour which is not bad, but it used to be better.

Better then what?
[LG Optimus 4X HD] dokii22:
what governor is best mix of perfomance/battery life ( ondemand,interactive,smartmax,wheatley ) ?

Yesterday for 8 hours of standby in Airplane mod he drained 23 % of battery ( sync Facebook,Tapatalk,Dropbox,Google Disk,Pages Manager ) :confused:

I'll leave next night with Better Battery Stats,but could that battery drain have cause in CPU governor ?
[LG Optimus 4X HD] chasepoes:
Some governors focus on performance and some on battery-life. There is always a trade-off. Which governor is best for you, nobody can tell.

Search this thread and you'll find an excellent link to a post explaining all the different governors and schedulers (Hint: It's on page 13). After that, pick one.
[LG Optimus 4X HD] dokii22:
Thanks,but I ask only which governor to use because I think some governor is draining my battery a lot in Airplane mode so I just wondered which one doesnt drain :)

Is it worth undervolting processor,could it squeeze more battery if I undervolt ?
[LG Optimus 4X HD] chasepoes:
+1

Using SlimBean V7.8 and OP V2.51..No deep sleep issues as of now.

P.S. Phone was not fully charged when I started testing. So 92% battery, does not mean a 8% drop in 52 min.

A governor on it's own is not responsible for draining battery. There must be a wakelock issue. Some governors use more power then others, but the power is only used when a process uses the CPU\GPU. So something must be keeping your phone busy in Airplane mode. Try to figure out what.

I'm using Wheatly which favors battery over performance, but I never play demanding games. Undervolting will save some power, as will decreasing max. CPU\GPU frequency. However undervolting can cause an unstable system and limiting max. CPU\GPU. frequency slows down the phone. It's up to you to find the correct balance of stability and speed versus battery consumption.

I don't undervolt (well maybe some undervolting is done in the OP kernel by default (don't really know)), nor do I limit my CPU\GPU max. frequency. With moderate use (some browsing, a few calls, whatsapp, checking mail) I'm getting about 18 hours out of the phone. Doing completely nothing it'll run for 30 hours or more.
[LG Optimus 4X HD] dokii22:
Thanks,didnt cross my mind that something is keeping phone busy,I have greenifiend everything and there is always 250-300 mb RAM free.

Wheatley is than a way to go ? I'm hoping just that the cause isnt notorious basend xmm wakelock ...

Better Battery Stats is installed and we'll se.

So,simply sad,tempering with undervolting isnt worth few % of battery because system could become unstable etc. ?
[LG Optimus 4X HD] chasepoes:
That's up to you to decide. For me it's not. However keep in mind that undervolting does not mean that your phone will become unstable. You'll have te test at which minimum voltage your phone will still operate reliable. That minimum Voltage differs from phone to phone. For me it's not worth the hassle.

And about the Wheatly governer: It's up to you if it's the way to go. Again, different people, different usage, different demands. Wheathly and Hyper work for me.I think that as far as battery-usage goes, Conservative is the most battery friendly, but can introduce some lag, especially in demanding games and stuttering in video.
[LG Optimus 4X HD] dokii22:
Thanks for explaining,I'll experiment with every governor and find suitable :)...

Here is screenshot,AndroidOS drains battery ? Maybe because I installed nightly

I wouldnt ask so much but I'm going for 2 weeks on vacation and charging will be limited and my phone will be in standby 1-2 days...
[LG Optimus 4X HD] chasepoes:
Android Process is a general description for all android processes. Use apps like Betterbattery or Wakelock Detector to find out which process actually is running. Look at the following screenshot. Android Process is doing something. When I tap on the process I can see which process it really is (shown in the green bar).
[LG Optimus 4X HD] Flying_Bear:
Its dreaded baseband xmm wakelock probably
[LG Optimus 4X HD] Demetris:
So..

Optimus Prime V2.53 is up.

As much as i tried to clean up cpu and gpu drivers as much as i could still there is lag when phone heats up :(

As a bonus for us now trying to beat lag we have a game console in our hands lol

I borrow as much code as i could from OUYA :cool:

When i beat throttle down on heat would be awesome to own an Optimus X4 HD :eek:

No heat issues, perfect battery.

Performance is slightly iffy, but that's because of the thermal throttling!

Otherwise contact Sygic or Navigon support.

This maybe a dum suggestion, but in System Settings -> Location..Have you allowed apps to use your location? If not then GPS will work, but no app will be able to read the GPS data.

A stated: I'm using SlimROM myself, and have done some tests:

Sygic: OK

Navigon: OK

IGo: Ok

Google Navigation: OK

All the nav apps work. GPS Fix is fast (using fresh A-GPS data) and accurate. When doing a cold-fix while driving, fixing takes a long time, but thats inherent to GPS. All apps work just fine.

I could never get that good a battery-life from stock-ROM/Kernel. In normal every day use I struggled to get 12 hours out of the phone. SlimRom V6.x with Slimkernel got me about 14-16 hours. With SlimROM V7.8 and OP Kernel V2.53 i'll easily get more then 24 hours.

But your miles may very..It very much depends on how you use your phone. But just go ahead and try. You can always go back to stock.

[LG Optimus 4X HD] Demetris:
Next build will have increased heat mark for throttle, new tegra drivers some undervolting and enabled quad at 1.5ghz. Last two go together so..what this means is that i will undervolt and same time unlock cpu to be able to use all cores at 1.5 ghz(currently 4 cores at 1.4ghz and at 1.5ghz is only 1 core) what matter most to me is battery life so if after UV and X4at1.5GHZ battery < than previously i will revert it.
