Droid Maxx Battery Time cut in half after May update! Anybody else?

[::Montgomery::]

No, I did cache clear and it didn't help. Once I switched to ART runtime it was all back to how it used to be concerning battery. Try it. Or don't but it worked perfect on my phone

ART article

For now, the potential gains in efficiency are difficult to gauge based on the version of ART currently shipping with KitKat, so it isn't representative of what will be possible once it has been extensively optimized. Thus far, estimates and some benchmarks suggest that the new runtime is already capable of cutting execution time in half for most applications. This means that long-running, processor-intensive tasks will be able to finish faster, allowing the system to idle more often and for longer. Regular applications will also benefit from smoother animations and more instantaneous responses to touch and other sensor data. Additionally, now that the typical device contains a quad-core (or greater) processor, many situations will call for activating fewer cores, and it may be possible to make even better use of the lower-powered cores in ARM's big.LITTLE architecture. How much this improves battery life and performance will vary quite a bit based on usage scenarios and hardware, but the results could be substantial.

Giving this a shot today.

Just to try it, I enabled ART on the phone last night. Boy, it took a long time to restart.

So far my battery life is exactly the same as Dalvik. One day isn't enough, probably, but it's certainly no better so far today than what I've been seeing with the Dalvik runtime.

If anybody else tried it let us know if it worked. Sorry it didn't work for you. After I switched to ART its been great. I plugged my phone in last night it was at 30% after 50 hours. For whatever reason it worked great on my phone.

I was using ART before the update. The update has turned my phone into worse than a G4 (my wife's phone) battery life.

I switched back to Dalvik and still have horrible battery life.

I also had and still have motoconnect disabled.

This is horribly frustrating. I hope the next OTA downgrade is better.

ART is working great for me so far, and my battery life has improved. 45% after 36 hours is vastly greater than the maybe 24-26 hours I was getting with DALVIK.

Weird how it works for some and not others. Glad it also worked for you. Im back to having to plug in my phone every 2-3 days since switching. Love it!!!

I'm starting to move into the battery life sucks since the update camp.

Lately I've been down to <30% after just, 12-14 hours, sometimes with as little as 1.25 hours screen on time. Android OS is always top battery drain. I realize it's just a catchall for many processes, though.

It may also be usage habits... I'm probably streaming iheart and Pocketcasts stuff a lot more, plus several bluetooth attachments like Withings Pulse, Fitbit, Pebble watch, BT headphones. The first two attempt persistent connections though.

I might switch to ART. Is there a list of apps is known to break?

I dont know if there is a list. Nothing broke on my phone. You can always switch back if you find something you need not working.

I just found this: List of broken apps in Android RunTime (ART)

Wikipedia is my only app that isn't working so far. That's really no great loss...

Absolutely, It is very bad and happened to me after the update; battery life went from 48hrs+ to 21hrs. I have been told to do an FDR. My issue is that battery drain happened at the same time I received the update and changed to ART. I just went back to Dalvik and will keep it for a day to see if there is any change in battery life.

Any time you see a bad battery drain after an update you should drain that battery to zero, recharge past 100 and then turn on your phone. Seems to work for my families Droids.

There is no reason, either software or hardware, that that should work.

I think my battery performance is still the same. Right now I'm at 52% after 20 hrs 6 min 20 sec and screen time of 3 hrs 1 min 54 S

What is com.android.chrome: sandbox? It says it used 2% of my battery.

That's the Chrome browser. Chrome is famous for sandboxing (i.e., separating pages and tabs into separate memory processes that cannot access each other's memory space) for security and reliability purposes (i.e., so if a tab crashes it doesn't take down the whole browser.)

Maybe not. But it sure seems to. Recommended it to friend who says it worked as well

Urban legend and placebo effect.

How many years did people claim wiping the battery stats file recalibrated your battery before a Google engineer had to blog about it doesn't work that way? This is the same thing.

You guys should install onexuan one power guard. It will not cure completely what you're experiencing but will help the standby drain.

That looks like it would help for rooted phones only. For some reason I'm wary about a company called OneXuan, especially when I go to their site and my Lastpass plug in tells me it refused to fill in data because the web site was presented in a potentially unsafe way (I have never seen that message from Lastpass before.) A probable Chinese company, potentially trying to get information just from attaching to their web site, on a rooted phone? I'd think hard about using this one.
