It's not the orb that heats up; it's the back of the phone that gets really hot. It hit 56 C while charging now and I rebooted to see if it would help (maybe some rogue app, but I doubt it since I haven't installed anything recently). It also was getting stuck at charging (as in % wouldn't go up) which I presume means that the phone is using as much power as it is getting charging.
[Nexus 4 Original Android Development] sailfast:
As I use chrome to browse, scrolling down pages, etc... Probably has something to do with the nearly continuous touch while browsing.

Temp shoots up 20 degrees like a rocket. 40 to 60+ degrees. And burns through battery...

I can understand some PPL like smooth... But I could really care less if it stutters a bit if I can stop wasting all that battery!

Nice main screen! That makes sense.

But for the back button, it's nice not to exit as before, but now it goes back, not up.

For example, if you go to support, then, without pressing back to return to main, deep into voltage (3rd level, where voltages settings), then to energy plans, when you press back, you should go to main, but, instead of that, it keeps energy plans in the header, but it goes through all previous screens (the tree levels of voltage, the support, and then main).

Thanks!

Anybody experiencing USB tether issues? I've been going back & forth between nandroids; one with r134 and one with r146. I can't connect for the life of me on 146

Did a search here and saw some mentions of UV causing tether issues--problem is I'm on stock voltages stock settings. I only ever touch color & gamma settings and trust Franco on everything else. Running latest Paranoid by the way, if that helps

That would clutter up the status page, to put the voltage of each frequency. Not everyone adjusts their voltage across the board.

The same happened to me yesterday and one other user, as far as I remember.

A reboot solved this issue, too. Did not happened again since then. Whoch radio are you running? I'm on the new .54 and maybe that's the problem, I'll monitor this issue for myself.

Best Balance preset oscillates between 384 and 1026 for me, anyone confirm?

Turning Dynamic scaling stops the oscillation so perhaps something off with the governor tunables set for Best Balance?

[Nexus 4 Original Android Development] markd0wn:
Hopefully r147 (I'd even take a 999 build) will fix data issues for both .48 and .54 radios, wouldn't be fun if 146+.54 fixes things and then 147 is fixed for .48 but breaks .54 :)

I'm also using .54 now but not sure if it's entirely resolved.. I'll let franco do his magic
[Nexus 4 Original Android Development] steviewevie:
I could be wrong, but I am guessing that r143 included patches to do with the HSIC (modem) stuff. The changelog said "ignorance is a blessing, trust me", and recently Franco mentioned his intention to put back some of those patches (following successful experiences on other kernels).

If so, I can certainly see the benefit of not detailing the changes at the time, for a better blind test.

[Nexus 4 Original Android Development] Foxnov1990:
+1 on this.

It's happening to me since r145. The device doesn't reboot and happened to me while my device is/was in idle.

So one example, I texted someone, locked the phone and put it down, then got a reply (so my screen lit up for 5secs). When it locked again I had to manually unlock it (so far so good).

At the unlock, I noticed my SIM was locked - so must have happened between getting the text and unlocking it again obviously - pressed the code and everything went like normal (no further booting process or nothing, as it didn't reboot)

This happened approx 20x over the weekend.

(Standard settings, only max freq 1350 and color settings)

Excessive heat, burning through the battery...

So, any advice on how to change the default settings to cool this beast down?

I UV -150 and it still is ridiculously high now.

As I mentioned before it used to hover around 40 while browsing with chrome but now shoots up to 60+ in minutes when I browse.

Yes it is smoother, but believe it or not I don't particularly care for it to be super smooth if it eats by battery and heats my home. :mad:

Any suggestions to tune it back?
[Nexus 4 Original Android Development] noneabove:
Yes, underclock to 1.35GHz max.

Under Hotplug Control raise the value of High, Medium, and Low threshold, this will keep you at lower CPU numbers for longer.

You can stop it from forcing cores online on touch input.

(these past two assume that 2 cores generate more heat than one high clocked one, if i'm incorrect someone will correct me)

In Governor Control decrease the hispeed_freq and the input_boost_freq.

In Custom Kernel Settings you can decrease the Thermal throttle threshold, this will make the kernel throttle your CPU earlier, so you can pop it down to 60 if you'd like.

Turn off loggers, cause well I mean.. Every tiny bit helps right?

Under Governor Control there's also above_highspeed_delay, min_sample_time, and timer_rate but I can't for the life of me remember which direction is better for battery, higher or lower

EDIT: Upon some searching, my findings for these values: set above_highspeed_delay lower (this is the how long it is forced to stay at your highspeed freq before lowering) set min_sample_time lower (this is the minimum time to spend at any frequency before it can ramp down) timer_rate increase it (this is the time it samples before increasing frequency)

Overall you will notice that the ui will probably lag more, apps will seem to go smooth slow for a tiny bit then back to smooth, but if you don't care about performance then this would work. Also, you can just play around with them to find a sweet spot :) happy hunting!

While doing this I realized the default IO is now NOOP, when'd that happen? :P

Also while doing this, I realized I haven't had to go into your app in awhile due to flawless performance, holy **** this UI is beautiful...

[Nexus 4 Original Android Development] The Gingerbread Man:
Sorry to quote myself here I just had a think and wanted my thoughts all together....

Beta feed back

Check out my temperature on my gnex

Colour control, no longer force closes but the tab on the left doesnt automaticly disappear like when you press any other item.

Selected Colour profile in status should only be used for applicable devices that can use it, ie only n4. Shouldn't be shown on gnex / n10 and colour control should be invisible on nexus 7 as its not yet possible

My thoughts on how I think the back button should be used as follows;

If you are in a sub directory it should take you 'up' to the previous directory until you reach the parent directory.

If you are in a parent directory then pressing back should bring up the tab on the left.

If you press back when the tab on the left is shown then a pop up asking confirmation to exit the app should be shown.

Example

A = parent (freq & volt) B = sub directory (voltage) C = sub directory (CPU voltage)

If you are at C (CPU volt) you should go to B (voltage) , B takes you to A (freq & volt), A asks for confirmation to exit. This is harder to explain in words than I imagined!

[Nexus 4 Original Android Development] nachordez:
The defaults for this kernel are the best balanced ones. Try them, and, when you see how they work for you and your phone usage, you can try to play with them if you feel you need

Edit: just for information, Franco sets as default the same settings he uses, so, give them a chance!

Under-volting doesn't save battery.

Noticed signal drops as well, started since I flashed 146. Never had such issues on any other version (and I started flashing from the 20s).

Thermodynamics laws says the contrary.

I thought I read somewhere that if you UV too much, not only will it make your phone unstable, but may even use more battery because when your phone needs to go balls to the wall, since the processor isn't getting the required voltage, there's more of a power draw to get it, using more battery than necessary.

I'm not trying to stir the pot but it seems when Franco releases a new kernel and there is something wrong with it people complain and whine.

I'll state that I've had drops in signal but most of the time I use my phone it's on Wi-Fi so it doesn't affect me that much.
