[Nexus 7 Android Development] Felnarion:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

Battery stats simply clears a file that tracks the battery usage;what you see in the battery screen in settings. It has nothing to do with how the number is displayed nor does affect anything but what I specified.

The problem you have is likely a hardware one. Will it hurt to let it drain? Probably not though that is another cycle on your battery. But it's not going to fix it.

If the problem persists through different rom installs, I'm afraid there isn't much you can do.
[Nexus 7 Android Development] Tone_Capone:
Do you know this through experience? I've read that a lot of people with this problem have it fixed with doing a full battery cycle. It's not uncommon for the battery stats to get jabberwalked with all the rom flashing that I do. If this doesn't work, I'm going to do a clean rom flash and see if that fixes it (I've been dirty flashing for a while).

Thanks for the help!

[Nexus 7 Android Development] nadiros:
Eh, maybe what FreaKRant was getting at is that many have had a frik of a time with their N7 after draining the battery completely. A quick search on the subject might be worth your while.

This kernel has some sleeping issues, wake locks here and deep sleep on trinity. I use rasbeanjelly BTW.

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

Yes some people have issues when their battery discharges completely but it's just a matter of letting it charge a bit. People freak out when the boot screen comes up and shuts off, screens seem to flash, and they start mashing buttons trying to reboot over and over. The N7 has a big battery so it needs some time to raise the voltage.

The whole battery thing is something that has been of interest to me for sometime and I have a fair but of reading about.

There is way too much that has become gospel based on a couple of sentences from the now infamous 'Google engineer'. Whose Google+ thread I have read completely.

I really suggest that those declaring that this or that is true or not true read some of the articles on Li-ion batteries at batteryuniversity.com before standing too firmly on your point. Here is the article on battery calibration http://batteryuniversity.com/learn/article/battery_calibration

I don't know whether this has been reported or not, but using M-kernel will cause the Adobe Flash plugin to show garbled image. Searching for 'flash' in a flash-happy thread is not gonna help much, isn't it? :D

Anyway, I am using stock deodexed 4.2.1 ROM with close to no tweaks. I used Sleipnir browser with Flash v11.1.115.36 (straight from Adobe). Changing browser gave the same result. Mind you that there are no actual error messages/freeze/lockups/crash. It ran and behaved just fine but the displayed images were garbled.

I am temporarily on Omega kernel as Flash seems to be fine there. Maybe you two devs can swap ideas about what's wrong? :D

I know it is not 'officially' supported by Adobe any longer. But, the fact is, there are still other custom kernels and the stock kernel that can run the manually-installed Adobe Flash apk. I have been running Flash just fine with my Galaxy S3 Jelly Bean and Nexus 7 at stock and Omega kernel.

Anyway, I DID search. Try searching 'flash' or 'Adobe Flash' in the search bar of this thread... The fact that the word has two meaning, it's hard to find the useful post among hundreds.

---------- Post added at 12:34 AM ---------- Previous post was at 12:26 AM ----------

Concerning the last version of M-Kernel, a35 does perform correctly here (i have had no problem with a33).

Note that a bug crashing Antutu (verify network time) was corrected in the last version (at first I thought cashes were caused by the kernel).

Also, an important update of SuperSU came at the same time a33 was published. Important bugs in this new version causing apps/system crashes were corrected today. So I suspect some of the problem discussed here might also have come from these bugs ...

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

This.

I'm doing a full drain right now and down to 7% (which is inconsistent with previous owners who have had this type of issue. Usually their devices die with a much higher battery percent remaining). I'm letting it die then going to charge while the device is off.

I'll let you know if my issue is corrected.

Same setup, rasbeanjelly same apps, haven't installed or uninstall anything.

It might be your attempts of fixing SODs that cause this? I've never had an SOD on this kernel and ever since you been trying to fix them the tablet started having wake locks.

A wake lock keeps the system up and prevents it from falling asleep. Things like GPS, Google sync, sounds, and others. They are there and part of android power management for a reason.

Hello!

Thank you for the great kernel. I had some SOD with a33 but none with a35.

I use my nexus 7 primarly for gaming and I'm testing all the possible settings with trickstermod. I'm not using any benchmark but I'm seeing the difference in performance with Temple Run 2. Every run is pretty standard and in a fast game like this one different performances are really noticeable.

I've increased the gpu clock to 520mhz and left the cpu to 1500mhz, a good compromise between heat and performance.

But also with this gpu overclock I always noticed some lag, micro lag. The game was smooth but sometime it rendered some frame slower than normal.

This happened with the touchdemand governor.

I've tried using the performance governor and finally the game was really smooth and the lag was gone.

I know that the performance governor force the cpu to stay at max frequency so i think that the micro lag is due to the processor scaling itself to meet the demand of the game.

But it is really annoying, so I'm asking if there is some mayor disadvantage for using the performance governor other than battery life (I really don't care of that, before installing your kernel I wasn't using my n7 anymore because it was slow in games).

I'm not saying that this micro lag happens because of your kernel. It always happened also with the stock kernel, I think that the design of the tegra 3 doesn't allow the soc to scale its power without ruining the smoothness of the game.

Thank you so much for your fantastic work.

It's really a case of personal satisfaction through use, and not worrying too much about the numbers. Also every time you run antutu/quadrant or whatever, you'll get a different score with identical setup, so I wouldn't have too much faith in these apps.

What I like about this kernel is that if you do not notice some lag, then there's normally something you can do to overcome it.

[Nexus 7 Android Development] Metallice:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a35

The cores will still hotplug so it won't be too bad. Battery would be the only problem.

Preferably you could use something like tasker to change governor when opening certain apps.

BTW I have no issues with touchdemand and temple run 2 with the graphics turned up to high.

You could also try increasing touch floor freq and/or touch floor time and/or touch min cores in trickstermod. That would be a better solution. In fact, the point of the first two is to prevent aggressive scaling after touch.
