Hi All!!

I got my Razr Maxx 2 weeks ago and have had the worst battery life ever. I came from a Droid X with an extended battery that lasted much longer than the Maxx's, which is ridiculous. I have the same apps running, but for some reason, my Maxx is getting nowhere near what it's supposed to. I am not a power user. I use it mostly for some surfing, checking emails, a few texts, 1-2 short calls, and some Words with Friends. While it does last until the end of the day, I see/read/hear about folks using theirs for 1.5 days or more without charging it.

I tried to investigate what was going on and here's what I found and need help with:
Per the battery usage, Android OS is usually the top or second most drain at a minimum of 20%. I never saw that above 3-4% with my DX.
Per Watchdog, the Linux process "suspend" is using up almost 50% cpu when the phone is just sitting there.

It HAS to be a rougue app keeping the phone awake, but I don't know which one. Like I said, my DX had the same apps but lasted much longer.

Already did a Factory Reset, and did NOT allow Google to use my saved settings as I heard that was one cause. I turned off updates to WWF and my Unlock with Wifi apps to see if it matters, but so far, it doesn't.

Any ideas? I love the phone, but worrying about the battery was the last thing I expected!!!!!!

 

huy_lonewolf, thanks for pointing out that thread. It's ayear old, but there may be some tips in there I can use. I am rooted and have calibrated the battery. I've even run it down to nothing twice! No help. This "suspend" process is the culprit, but what's behind it, I can't seem to figure it out. Even if I got a new phone and put all my apps on it, I'd get the same results unless my OS is defective

 

I don't think there is a direct way, but if I find the damn app that's causing it, it's G O N E!!!

 

Well, so far, I've found that several others see the "suspend" activity, but no one seems to be able to pinpoint the cause. It's been mentioned that Google knows about this but hasn't issued a fix, but I find it impossible for that to be true, otherwise, we would all have the same issue. Now, if Google knows that some apps can exploit this and won't issue a fix to control apps gone bad, THAT I will believe.

I've added a couple of apps to monitor wtf is going on, but I was really hoping for someone to jump on here and say, "It's this, you dummy!" Hell, I'll take the heat if it's something simple, but that doesn't seem to be the case.

 

So overnight, I fully charged the phone, got up at 3AM to unplug it. Left WiFi off, so it was just running on 4G. By 6:30AM, it was down to 95%. With the apps I used to monitor the drain, this is what I got:



Kernel Wakelocks - top 4:

• alarm_rtc 413 instances
• ehci_wakelock 267 instances
• PowerManagerService 1336 instances
• oob-wake 124 instances

Partial Wakelocks - top 3:

• AlarmManager 1149 instances
• ActivityManager-Launch 89 instances
• IMS_Lock 11 instances

suspend was active for over 16 minutes. Also, about 5:30, the suspend process triggered an alert for cpu use at 78.5%!!!! Is there a bug in my phone, or is it an app gone crazy? If the former, I need to exchange it. If the latter, I need help identifying the culprit.

 

My 4G is pretty good. I've got Bad Ass Battery Monitor, Battery Monitor Widget, and BetterBatteryStats checking out what's going on, but they don't point to a specific app. They all tell me suspend is killing me, and a bunch of wakelocks hitting, but again, no specific apps. I'm uninstalling ones I think are responsible, but no luck so far. Dammit!

 

CharlieD,
I've suspected all along that suspend is being used by an app that wants to keep waking up the device for some update. Which one? I have no clue. I have deleted some apps and frozen others, but it seems to still be happening. I've posted this on the Moto forum in hopes they can assist, but one "moto expert" says it's because I'm rooted. How does that matter? Beats me, but I'm not unrooting it!

Let us know if you find something!

 

Yeah, they're full of it. But as soon as they know you're rooted, they use that as the reason for the issue and the excuse not to help. Anyway, they suggested Lookout could be an issue. I doubt it, but I may try taking it out.

 

Yep. Lookout isn't it. I have been deleting stuff that needs constant updates, like Espn and Sportacular, but kept MLB. I also froze lots of bloatware. I seem to be better off today than before, but it's been an out of pattern day today. I'll see the results tomorrow and let you know as well. Let's get this figured out!!

 

Charlie, sounds right. Basically, without reading that link yet, an app or apps don't play nice with the wakelocks. I believe it because I didn't load anything new on my Maxx that wasn't on my DX.
The Moto folks showed me an app called App Dragon that will list all installed apps. If you want, we can compare to see if we have any in common. We can do it here or via PM. Let me know what you think.

 

Charlie - I just compared the lists and emailed you back!

 

biggiesmalls657,

So far, the apps I uninstalled are the following:
Sports Insights
GetJar
eBay (notifications turned off, but app kept sending wakelocks??)
At the Ballpark
4Shared
SMS Backup & Restore
CalendarSnooze
CircleLauncer Light (why does a folder app need to keep the phone awake???)
Mr. Number
Sportacular (I put this one back this morning with no ill effects so far)

Unfortunately, the apps we had in common were very limited and unlikely the source. As Charlie stated, it's probably more than one and it's an incompatibility issue with the kernel we have.
