KitKat & Battery Life

[LinuxWeather]

You can just switch it to ART. It will reboot and rebuild all you apps automatically, Just let it do its thing and your set.

But some apps will not work in ART yet as I've seen in other forums just FYI so don't freak out if a few force quit

Good point, so far mine have all worked. Knock on wood.

Have you seen a list of apps that are known to not work with ART?

How do I switch over to ART? Also, if I don't have Kit Kat yet, would there be any reason to switch?

Settings--->Developer Options---->Select Run Time and pick Use Art. HTH

ART is only available with KitKat, so, no, you'll have to wait.

If I switch to ART, and don't like the experience, could I switch back?

fat-fingered and Maxx-ed out.

Yes...

If you switch to ART and then switch back, is it a long process or is it as simple as switching messaging apps?

 

[Einsteindks]

The OS simply re-processes all apps in Dalvik mode, not all that long, relatively speaking.

The switch from Dalvik to ART or backwards requires a reboot and Dalvik->ART reboot takes about 5-10 min because the system has to rebuild all apps. I dont know who long ART->Dalvik reboot takes as I've never done it

I've done it twice and it rebuilds the apps faster going from ART back to Dalvik

Is anyone else having just horrid battery life with the 4.4 update?? I switched my apps to art about 3 or 4 days after I got my update and even with the other option I haven't gotten more than a 1 day and 10 hours on it. Before the update, I was close to averaging 2 days on a single charge. Took a major hit with 4.4. Anyone have any thoughts or suggestions??

My X's battery life took a big hit with KK (from 16+ hours and down to 20%battery to 10 hours and 15% battery). I returned it because of the battery hit. I'm assuming my Maxx will take the same hit (unless they go straight to 4.4.2).

I am as well. I'm probably losing close to an additional 1% an hour since the update. I haven't had time to do a factory reset; I should get time Monday, so that's probably the plan to see if that helps.

After my first full day with Kit Kat, battery life is considerably worse than JB but I've read that I should wait a minimum of 3 days after upgrade before assessing battery life. My biggest drain in apps is kernel, Google Music and media server. Those three apps account for approximately 45% of the 65% battery usage for apps.

Thanks for the reply guys. Glad to know I'm not the only one that's having issues here. To me it looks like the update roll out has stopped, hopefully Moto is fixing the problems that I, and a lot of other people have made them aware of during the soak.

I'm not having any issues with the above apps listed, my biggest new consume is the os itself. It never used to be n the 20% range before KK, now it constantly hovers around 25%, I know the reset is a good way to check things, but I really want to avoid doing the factory reset. I already cleared the partition cache once.

Another big factor is signal strength, its significantly less in KK than n JB, which means the phone is looking harder for a signal, same deal applies for WiFi for me too.

Hope they issue a bug fix asap.

Are you measuring signal strength by the bars in the status bar or by the actual signal in settings / about phone / status / network type & strength? Bars mean little; don't go by that. If the latter, I'd be very surprised if it was any different from before. The update won't change the physical radio or antenna, and the signal should be exactly the same. It would only be possible that the firmware would get better, not worse.

Your battery will return to normal (long life) after a bit. I received the update day one. Just got 61 hours out of the battery with mod usage. Hang in there it will get better.

That's quite a leap of faith there.
