    I just checked my battery and 39% is being used by an application that is named rild.

    It looks like a Motorola thing...maybe an OTA update? Anyone else seeing this? I'd do a screenshot but don't know how on my phone:confused:

    Thanks for any help.

    I wouldn't be too concerned. That 39% is only 39% of the actual use, so if the phone has used 10% of the battery's charge capacity, then the app you're referring to has only used 3.9% of the total for the battery. You must always keep in mind that everything is relative. Don't get so hung up on the actual number, because the number is only a representation of the portion of use, not the total use.

    Thanks for the reply Foxkat. I left out one of the most important details: my battery use was also tanking. I was at 30% remaining by early evening with low use and much different than what it has been. Ended up powering off and installing my screen protector and will see what happens over the next few days.

    Update: battery drain not just me

    I posted yesterday about a big battery drain by a process called "rild". It appears to be hidden and doesn't show up in running apps. I rebooted and it appears gone, but I've done some searching today on this, and there are posts on other forums about this process eating the battery, including the Motorola forum, so this isn't a unique issue albeit apparently an uncommon one. Unfortunately, I haven't stumbled upon any answers that really identify the problem or cause. I think it might be specific to Motorola but not RAZR as there have been other inquiries about this happening with other models.

    If you see this on your phone, please post what you are seeing. Thanks.

    Android's Radio Interface Layer (RIL) provides an abstraction layer between Android telephony services (android.telephony) and radio hardware. RIL negotiates the dial and connect sequences between the Android phone and the Telephone "Vendor" RIL. Between the two RILs a phone call is initiated.

    The RIL daemon (RILD) initializes the Vendor RIL, processes all communication from Android telephony services, and dispatches calls to the Vendor RIL as solicited commands.

    The process follows the following protocol:

    Android dialer dials number
    Unix sockets initiates the dial sequence
    RILD initiates the function call and there's an immediate return of the notice of action to the Unix socket
    The Vendor RIL performs an onRequest for the AT0 or other IPCs
    The Vendor's Baseband performs the dial process
    The Vendor's Baseband completes the dial process
    The Vendor's RIL performs a Listening Thread to "Connect" or other IPCs
    Android's RILD receives notification through an onRequest Complete
    Unix says Dial Complete with an Async return

    So, the above is a normal process of performing a phone call. The reverse which is less complicated is what happens when a call is received. RILD is an integral and necessary part of the phone call process and the Smart Phone would not be able to perform the process without the RIL Daemon.

    Thanks for the information. That may be, but I made/received 4 calls with total time under 4 minutes, and when this process started running, it drained my battery from 80% to 30% in 3 hrs (and that wasn't when I was making the phone calls.) My total time on was 12 hrs before I turned it off completely and recharged.

    It showed up in battery use as "rild". More information about the process yielded the following:
    CPU total 2h 56m
    Keep awake 4m 30s

    Included packages:
    com.motorola.setupwizard.phoneservice
    MdmMoveNotice
    Orientation Notifier
    Dialer Storage
    ConnMO
    Programming Menu
    Phone
    SIM Toolkit
    com.motorola.phoneaddons
    com.motorola.hiddenmenu

    At the time of turnoff this process had used 45% of the battery use, with display at 24% and OS at 11%.

    So while "rild" may indeed be related to making/receiving phone calls, there was something else downright weird going on, and apparently I'm not alone in this phenomenon.

    Please don't misunderstand my previous posting. I wasn't trying to say that excessive battery use was normal, quite the contrary, but what I was saying is that this RILD isn't some rogue application or virus that's hiding below the system and therefore not showing up on the running processes list.

    For the phone to have had the CPU tied up for almost 3 hours while only keeping the phone awake for 4 minutes 30 seconds for this process (which confirms the 4 calls total of under 4 minutes) speaks of a problem. I would try running in Save mode (http://www.droidforums.net/forum/droid-razr-support/200128-accessing-safe-mode-your-razr.html ) for a day or two to see if things are different. It may be another app that is causing RILD to stay active and not release after receiving or making a call.

    Please report back your findings.

    No misunderstanding...thanks for the help. Good to know it its legit and not a virus. From what I can gather it seems to a) be a one-off thing, b) Moto related, and c) not only Razr. Phone is fine today and behaving nicely :) Curious if others are experiencing this too.

    Yes I have been seeing this behavior for the past few weeks, with no phone use at all, just standard email polling, my Bionic will suddenly be dead or close to it on my desk. When I check the battery stats its clear that the rild proces was the culprit. I usually turn the phone off and recharge, that seems to clear things up for a day or two. I am suspicious of some apps that may be causing the problem, but haven't had time yet to troubleshoot completely.

    A few days ago I noticed my battery life was really poor and I had the infamous rild usage. I hadn't done anything different so I was surprised.

    I ended up rebooting it several times but eventually it resolved and hasn't returned.

    Not sure what started it but maybe that will work for you.

    The reboot seems to do the trick. I haven't had a reoccurrence so it seems like a random thing. Noticing it before it drains the whole battery it's the tricky part!

    Wow, I jinxed myself! I noticed the battery indicator seemed lower than normal and I checked and sure enough, that demon rild is eating my battery again! Battery consumption down to 70% with 27% being consumed by rild. I've restarted and will see what happens.

    That's interesting. I wonder what happened?

    Not a clue. It took the equivalent of a battery pull to kill the process. By that time rild gobbled up 43% of the battery and it went from 70% to 60% in a matter of minutes. It's been fine the rest of the day so far. Have you had any more occurences?

    Bizarre! No, I haven't had any more occurrences and I've checked a few times. It would be interesting if it could be traced to a certain app or process but that would take some detective work - and some luck!

    Hope you're done with it now.

    The first time I got that RILD process I had to shut my phone off and reboot. The next time I got it I wasn't able to get rid of the process with just a reboot , I had to actually turn the phone off for a minute or two and then reboot. I haven't seen the process since.

    Good thought. Computer's do get run away processes sometimes and, although it's easy to overlook, the Razr is a computer.

    I was going through airport security and the signs all said to have your laptop out in a separate bin, etc. So I asked the TSA guy if he wanted me to do that with "this" (holding up my Razr) and he replied, "No, that's just a phone." Uh, okay. But don't say that too loudly because many folks think smart phones are replacing pc's. During the last three months of 2010, 94m PCs were sold – and 100m smart phones. But hey, who am I to argue with TSA? That's a good way to miss your flight! Shutup.gif

    I too am having a rild issue. I bought my RAZR in late November of '11 I've never really had an issue with the battery. I charge it in the morning and it would last till that night. Granted I really don't use it a whole lot. But even when i do watch videos and such I never really had an issue to complain about. However, this one started yesterday. I was texting and suddenly my battery is at 30% and my phone goes to battery saver mode which is how I have it set in the smart actions. Now, the only thing that was different was I downloaded the Facebook messenger app, so I deleted it and the problem did not go away. I looked the see what was draining my battery and it was the evil rild. Now I know what it is, doesn't change the fact that in the past five months I've never seen it on my battery usage screen. Very irritating.

    Ok, rild for two days and now back to normal. Just wish there were more exact answers on why it shows up temporarily.

    I had a return of "rild" yesterday, too. I'm with you, I wish there were more answers on why this is. I haven't yet been able to find a pattern.
