[Q] What's Causing My Battery Drain? - Motorola Droid RAZR

Razr MAXX running ICS leak
I decided to let my battery run down to zero last night and let it charge while I sleep. I got to work this morning and just notice my battery is at 50%! The only change I really made yesterday was re-enabling smart actions, and setting a wifi connected trigger to turn data off. I'm thinking this may be the cause of the drain. Here are some screens.

I have no clue what "deleted_wake_locks" is. All my google results seem to point to wifi usage, and am thinking there is an issue with Smart Actions and Wifi might be the culprits.

There is an app that is not letting your wifi sleep.
Something is keeping your wifi on all the time and eating up your battery. Check out this app in the market and report back with the results, it's called "My Data Manager" and it will tell you which app or process is eating up all your wifi. Let me know what it says.

This might be helpful as well, this guy changed the DTIM interval on his router and it fixed his issue.

I've found on the stock rom, the Verizon wifi control app works well for turning wifi on and off by cellular location, ive heard tasker does this well also. Ive had no luck with smart actions. You also might want to go to settings, wireless, wifi settings, hit menu, then advanced settings, then change the sleep policy, if you have root you could also change the scan interval by editing the build.prop or using rom tool box. But do kill the wake lock, it not only keeps the wifi from sleeping, it also keeps your phone from going into its low power state

I am having a similar problem with my Razr (not MAXX). Just today i noticed the phone getting hot in my pocket. I then saw the battery was almost dead after only 4 hours unplugged and very little use. I recently rooted and flashed the clutch extreme version. I dont use wifi. I have autokilled everything useless, ive checked the running apps and nothing wierd seems to be running, in the battery usuage, after 4 hours unplugged "google services" and "android os" both had 33% of the battery use. But like i said i cant see what is draning it...any ideas?
Thanks in advance.

Even im having some issue there's a process called Media which always is 92% and eats lot of battery.....so is there any way to kill this process?

If your phone is rooted my advice is to use ti backup and freeze the bloat ware the list of pre installed apps safe to freeze/uninstall can be found in the forum, when your phone reports "android os" "system" "media" its a general term that covers built in apps. The major culprit ive found is Verizon's back up apps, media is probably motocast, try mulling around in the settings and set the sync settings to as minimal as possible, also if you guys don't mind, I'm curious about this, when i first had batt life problems i ran voodoo ota and disabled root and forgot to re-enable root, with bloat and all i seemed to have better bat life, anyone want to test and see if its the same for them? Wondering if Verizon is being sneaky, and pulling carrier iq -esqe info from rooted stock

Never let your battery go down to zero. That is very bad for lithium batteries.

ok guys i found solution to media process.....Android media was trying to update it's music player and galery and since there were some media files which were too big in size and seems other files were corrupt so Media was trying to read them and thus eating up lot of clock cycles and thus draining battery. So once you identify which media file is causing the problem then media process get's minimal. About android OS process there's nothing we can do except to freeze some bloat.

Another way to disable media, though you have to do it every time you reboot, is to kill the process in running process in settings then applications. Mine does the same thing.

I was under the impression that the android os has a safety built in that keeps you from actually reaching 0, and the process of draining your phone until it shuts off, wiping battery stats in recovery, and charging too full while shut down was more to retrain the os to see 100% at a closer point to full and 0% at a lower safe point of shutdown... i know flashing roms not at 100% battery can muck up the scale, a good indicator is that your phone shuts off from low battery, you reboot and it reports a something like 20-30% battery

I would assume this is true for all android devices but at least for Razr I can assure you that it will turn off the phone before the battery gets below the critical voltage. That said it is almost always better to recharge well before it gets that low and as much as it is possible charge to full. I almost always charge over night.

[Q] Managing the Poor Battery

Just picked this up for my girlfriend. I currently have an Incredible, rooted with CM. She will not (or at least I havent convinced her to) let me root at this point.
What are some ways/apps to help manage the battery?? Connecting to Wifi at work will help the 3G/4G search drain but I need to take it further.
I'm looking for all suggestions, from sync setup to brightness setup to animations to apps.
Set the screen to automatically turn off after 15-30 seconds, use the LTE on/off app to disable 4G by forcing 3G only unless you need the extra speed (assuming you even have 4G where you are), don't use dynamic themes, limit how often apps sync data, set the screen brightness to automatic, and use a task killer to manually kill (don't use auto-kill unless there is an auto-kill whitelist as most apps don't need it) stubborn apps that want to constantly run in the background.
If and when she is willing to let you root it, then use SetCPU to underclock when the screen is off and freeze (or rename) the built in apps that she doesn't use as many of them will not only run on boot but will keep reloading themselves if killed.
Using all of that, I can get over 30 hours on standby assuming fairly light usage (a few hours of talking via bluetooth). Of course, with heavy usage (such as with streaming video like the tv.com or epix apps) the battery life is much lower.

Use juice defender from the market to turn off 4G while the screen is off. This added about 4 hours of battery life to my phone, standard battery.
Juice defender and green power are both great apps. As far as killing tasks, I've read that killing tasks can actually decrease your battery life because of how android handles the tasks and ram.
Androids tries to keep as many apps in ram to make loading faster, and if you kill all apps, the system will start loading them again, using more of your cpu, therefore decreasing barry life and slowing the phone down. Android had a very good and smart task manager built in to the os.
That is my understanding. If I am wrong, please correct me.

If you can't root, the next best option is a spare or extended battery. Apps like Juice Defender help a little, but no software can replace a real battery. I used JD until I bought some batteries on ebay.

It can, but there are also quite a few apps that will keep consuming lots of CPU cycles in the background. Some games are like this as well as some of the video streaming apps.

This is true. Autostarts (in the market) prevents such apps from running in the background & draining battery.

I looked at the battery info and saw that nothing was running, but the phone kept going "awake" intermittently. Looking at spare parts for the detailed abttery info i didn;'t see anything that was holding wake locks...

Turn off wifi when its not available.. scanning for it can drain your battery quite a lot. Obviously turn 4g seach off if you are not near a 4g area. I have my screen turned down to about 30-40% and it stays there(its quite bright at that % anyways). Dont use any task killing programs.. android OS has a very nifty task killer program on it already where it prioritizes what tasks stay running or don't. I have heard good things about juice defender you might want to check it out. Turn off sync for all apps and put the manual sync widget on your screen and that will also save some battery. Those should help some but a big one which killed my battery before I rooted was the bloatware apps that HTC puts on the phone. Blockbuster runs something in the background that will kill your battery. It is called PMVtpServiceStart force stop it in running processes and open up blockbuster then install the latest update and then force close it again and blockbuster. That should stop it from running. However you have to do this every time you reboot. Those are all my suggestions.. maybe buy a car charger if you drive a lot. I have one and its nifty to just plug it in whenever I drive to get a little bit more power! Good luck on your phone. PM me if you have any more questions.
i loved juice defender and used to recommend it to everyone, but a week or so ago, i had an issue to where my 3G stopped working altogether. I could still turn my 4G on, and force 3G to come on to check for software updates, but then it would go back off. After 24 hrs of no 3G, i uninstalled Juice defender, and after a couple of reboots, 3G came back on.
I guess there is no way to prove for sure if it was juice defender, but i feel that it was. If you are willing to take the risk, i was able to get 1.6 to 1.8 times more battery life out of juice defender.

i'm not sure, i typically had my 4g turned off unless i had a big download or was streaming/using mobile hotspot. It would automatically shut the 3G off when the screen was locked, but then one day the 3G just wouldn't come back on. I went into the wireless network settings and flipped the LTE back on, and that worked fine. With my work, I am in/out of 3G-4G coverage, so having just 4G is unacceptable. After uninstalling juice defender and restarting several times, it came back on. Could have been a coincidence, could have been the MR2 radio, could have been a combo, i don't know.
Does the TB continue to search for 4G when the screen is off? Or does the 4G only drain your battery when you're actually connected to it?

[Q] phone awake % = terrible battery life!?!?

Did some searching re: other people's battery woes, but didn't see anything specific to awake time, any help appreciated, including a link if the answer to my problems is posted "out there" somewhere!!
I cannot figure out what is draining my Atrix battery so fast?? On Froyo, it was reasonable, but since GB, it licks! Also, on Froyo, you could see what processes had used battery! Using *#*#4636#*#* you could see usage statistics that told you specifically which PROCESSES had consumed what %, with the option to toggle between since last boot, since all time etc but in GB this is much less useful, just tell you apps ie launcher, browser, gmail etc with a launch count and unhelpful # of milliseconds?!?
Do you know of any way to find out the type of info that Froyo used to provide, or a market app that will tell you more than just which apps launched?? When I look at battery and data mangager/battery usage my phone idle % is HUGE, and the phone "awake" bar graph shows my phone awake almost constantly despite "screen on bar" graph having large gaps where I obviously wasn't using my phone.
For example, I purposely did not put on charger last night at bedtime, battery was at 62%, woke up 7 hours later, battery at 21% !!! Something is keeping my phone awake &/or constantly waking it up, but I'll be damned if I know what. I have minimal apps installed since flashing Red Pill, just bare bones, thinking maybe one of my non-essential apps was the culprit!? I used to think it was all blur, but tried CM7 beta, and it's bad battery life dispelled that notion.
Also tried Juice Defender, but no improvement, I guess b/c whatever is waking my phone up overrules juice defender in priority??
Please, is there anything I can do before I launch this Motorola thing off my 12th floor balcony and go out and buy myself another Nokia (old reliable)??? I'd really miss the fingerprint scanner, but it might solve my migraine problems since 2.3.4 entered my life!!!
Thanks,

Try flashing .30P radio
my about phone/baseband version says:
N_01.77.33P
Does this mean I have .33P radio, and if so, would "downgrading" to .30P be better??
Thank-you.
unless the radio has a problem getting a signal then is probably not your radio. you can check this by going to battery usage and then cell standby and it will tell you time without signal. if this number is high then it might be your radio. if not then you need to find out what app is staying open and draining your battery. check your running services and try to figure out whats running in the background. you can use apps like system panel and os monitor to find rogue apps. also install a reliable rom like Homebase or CM7
radio checked, not the problem, 0% w/o signal, tried sys panel, didn't shed any light on "awake" problem, will have a look at os monitor.
thank-you neotekz
Turn off background sync if you have it on. That drains a lot if it auto updates in a weak signal area...

if you are having trouble finding the problem just try flashing homebase or cm7.

Razr has Androids 'suspend' bug that kills battery life

I've been doing a lot of research on this and it appears that our Razr has a bug that has been plaguing alot of Android phone. The 'suspend' bug. I noticed my phone was using alot of battery just sitting overnight. Sometime I'd wake up and it would be dead, which didn't make any sense. So I dl'd Watchdog to see what was killing the batt and it would get a warning about a 'suspend' process. This would pop up several times when the phone was just idle and not being used,with screen off. So I Googled it and there are alot of folks on various Android phones experiencing this problem. Here is a link to one site that is working on it or has been: http://code.google.com/p/android/issues/detail?id=11126
If you do a search on it, there are quite a few places that it's popping up on. I can't figure out how to get it fixed but I do know that this is one reason our phones are not lasting as long as they could. They're being drained when not being used! Now this may affect alot of folks or just some but it's a definate problem, I know on my phone it sure is!
I've also noticed there's a huge drain in battery use coming android is. Hope there's a fix for this.

It's not a program but a process of the Android OS. It's likely part of the rom for the razr like a setting that motorola stuck in that prevents the low-power cycle that should happen when you put in sleep mode. Probably could be fixed once people start making roms or if they roll out that OTA for icecream sandwich.
Same here, hope this gets fixed soon .
And as I have pointed out in other threads, having Wifi connected magnifies this problem quite a lot (for my phone at least). If I use CPU Spy to monitor sleep time, if Wifi is connected, I get almost zero sleep time even if the screen is always off.
What I've found for battery drain with screen off:
Wifi on, cell data off (using smart actions): 4%/hour
Wifi off, only 3g data on: 1-2%/hour
4g falls in between somewhere.
It would be great if Juice Defender could be programmed to deal with this Suspend Process.
Which watchdog did you install? the free version. I would like to confirm this and I suggest others do as well.
Yea just using the free version of Watchdog. Make sure you enable the search Android processes also.
BetterBatteryStats shows it as well under "Process"
I'm also having this issue. I was getting really good battery life (compared to my work phone, an Evo) for the first few weeks and then all a sudden the battery bombed on me. The standard Android battery use info only showed "Android OS" as the culprit (and would show like 60-80% as of late) of battery going to it. I downloaded Watchdog Lite and then this morning after I had the phone off the charger it was giving me the alert that the suspend process exceeded threshold of 51%.
I DO use wifi and that was actually helping with battery, but I have it set to not use when screen is off. Now, that being said if suspend is hanging on it trying to disable that's one thing, but I've got those settings in juice defender and in the OS config.
I have the exact same issue
I don't know what it is, haven't checked but...I lost 13% overnight in about 8 hours, too much IMO. Still get awesome battery life though, can't imagine if that was gone.

I lost the same last night. Unplugged for 8 hours. Not turned on. Was awake for first hour at least. Didn't go to suspend mode for awhile

I have the Razr for about 2 weeks now, and I have yet to get an issue.. However, maybe for the handsets affected, a patch will come out to resolve the issue. Or maybe, just maybe they will just wait and release it complete with ICS for the Razr.

Well, I think I figured out what was causing the issue in my case. Anyone else running the app "Screebl"?

Yep, use it my Razr.
Anyone experience something (a term I will borrow from the Nook forums, ) "Sleep of Death"? It has happened three times to me on my Razr in two days, although in the last two it hasn't happened.
By SOD I mean that I unplugged the phone from the charger fully charged and within a matter of 25min to 6hours the phone becomes unresponsive . No power button working, plugging into charger, nothing wakes it. The only time it responds is after the hard reboot ( by holding down power and volume - for 10s)

Well, after disabling Screebl I haven't had anymore wacklock issues. Watch Dog isn't reporting on suspend anymore, and betterbatterystats is now behaving as well.
I also have Android OS taking up to like 46% of my battery. However, I now got around 20 hours battery life with a few txt, calls, music gaming etc since I turned the policy of the Wifi to go off when screen is turned off. Weirdly, it also appears to improve my battery life even when my WiFi is already turned off. Guess you guys can give it a try. But Android OS is the main energy user of my battery. Didn't have that on my Xperia X10
I have two questions:
1. Does anyone know the correlation between CPU usage and battery burn? I'm seeing Suspend consistently burning 3-5% of CPU, but haven't seen how that directly translates into batteyr burn. There should be some sort of mathematical relation between X CPU = Y battery burn.
2. Even though suspend is eating low cpu cycles, the battery dropping 10-15% overnight with nothing going on is still ridiculous. Any ideas on what else the probelm is?

Razr Battery drain discussion

Hi All, I have been using the Xda for long time and I am a bit greed and I never register, yep that's right, hate plz come.
But anyway, I have used too many phones that I can't even remember.
Last couples of week, I got rid off my Nexus one and got A Razr, but the disparagement start right with the battery life!
First a few days, I was using only wifi, as one of my number does not has Web pack on it, and I notice a horrible battery performance on the device and I am
Later on, I activied my internet on phone and here comes my theory.
I notice the Wifi is always running for some reason on the background even if I set it as turn of when screen off, when I check the battery usage, it shows almost every second that wifi is on. That should not be right, it should turn it self off when screen off, and it is not doing that.
Second of all, later on, I noticed something like *WIFI* shows under battery usage, and I was thinking what the heck is that, cause there is another "WIFI" still showing, and also something called" .com.motorola.contact. something like that is waking the phone and using the wifi as well.
And there also something like"motorola.home" running and using wifi for ages. Very strange.
OK, then I went out today, yes, I most of the time stay @ home, na I am joking..
I am mostly in a place with WIFI, home, work place, and Uni. All wifi here and there. Today, I took train 3 hrs total out and back from Birmingham to London for those who like stories. it was 1:30 afternoon battery @ 80% then I listen to music for 1 hr and use whatsapp quite a bit(battery hunger app even on iOS)
On the way back I played GTA 3 for one good hour. and it is now 9PM, and 15% left, as later on I tweet a bit, web a bit. which is good, also I took underground so signal is not always there.
After all these my question is for those who had the battery drain, are U in a wifi enviornment quite a bit time and use wifi?
If so, set the wifi sleep policy to Never(this actually will help) and while not using wifi to use heavy data stuff, turn it OFF and see what happen.
Also turn off GPS espically if you have facebook on phone and also the using wirelsess connection for location, turn that off as well.
BTW the GPS on Razr is reallllllly fast on location, it took 5 second to find me from cold boot. Awesome.
And I don't use task killer or smart action, I think using sensor and active these sensor to save battery while they are using a lot juice is not so smart.
BTW: due to I am on and off subway, my iPhone4s dropped a good 15% without any use, it just sitting in my pocket. (as for now, Android is the fun bit, iOS is the backup, as it does hold battery better a bit...lol)
I am on 2.3.6 (651.167.19.XT910.retail.en.EU)
I flash the rom couple of times, it all shows me WIFI is doing some strange thing.
Today still draining and I use a data usage checker and find that moto blur is using a hug a mount of data, WTF!?
I find battery performance vastly better on wifi than 3G. Mine has had atrociously bad battery life recently, so I'm backtracking through stock ROMs to see if I can replicate the setup I got 5+ hours of screen-on time with.
Gotta love those updates. The sooner data works properly in custom ICS ROMs for the XT912, the better.

Sent from my XT910 using XDA App
I've been using SetCPU to create profiles on the ondemand governor and extrapolating from my general usage during commute, news/texts/im, fair amount of screen on time, I'm getting around 10% drain per hour which is fairly nice. With screen off and 3g running leaving the phone to idle, it drops to around 3-4% per hour which is significantly better from what I was getting right out of the box.
Battery test for Motorola RAZR XT910
Yesterday I decided to do a simple test with my new smartphone, a Motorola RAZR, I shall not charge until he get just 15% of battery remaining. So here I will put the results and thoughts about it.
8:00 AM: I woke up and took XT910 off the charger. Wi-fi was turned on;
8:00 - 9:00 AM: I passed one hour using Pulse to read some news, once or twice I shared some news in the Twitter and Facebook, with the Wi-fi on, of course. The Battery got 85%;
9:00 - 10:00 AM: I started to use Whatsapp to chat with a buddy, took at least 45 minutes of intensive use, battery got 70%;
10:00 - 11:00 AM: Cellphone in stand-by, BUT with the wi-fi on, waiting for someone, battery got 60% yet!;
11:00 - 12:00 AM: That one appeared, so I used Whatsapp again for 30 minutes, and battery got 50%;
12:00 AM - 2:00 PM: Two hours with the cells blocked, but still with wireless connection, 40%;
2:00 PM – 4:00 PM: Motorola in stand-by, now with the wi-fi turned off, so, in the first hour, he keep 40% and in the second, he got 30%;
4:00 PM – 5:15 PM: The final test, I passed just one hour playing Ceramic Destroyer without stopping, the battery got 15% and then the phone asked for charging!;
Well, the battery last for 8 hours with wi-fi turned on almost all time, so I think it's was fair, BUT, the battery status is a bit fake, I don't think that the information was correct, but, it works when is a simple test, you know, right?
We all know about the 1,2 Ghz processor, this drains a lot of battery, but the real villain is the connection, wi-fi or 3G, they both spend so much energy of the cel.
My last thought is... always charge your phone when it's possible, even if you don't use in an intensive form, I hope that you'll not have problems because a low-batterys cell phone.
One thing I've found is that when my battery is draining like a tub it's has nothing to do with any data connection. In running apps there's a media process that keeps my phone running at full bore. If I just kill that I get dramatically better battery life. Normally when I don't have to deal with that I can last all day with a quick touch up charge during the middle of the day. This on my xt912.

your right, certain apps can affect battery life so it is ok to kill running task. however just want to make sure other users know that using task killer to constantly kill many apps is not a good idea! most of the apps will prob restart and this cycle will only drain your battery more. whatsapp is a good example, even they state on their homepage you should remove from task killing as battery would drain not just from the constant restart of the app but also the fact that it would continue to regain connection to their server whenever it restarts.
try use a dark colour like black as you know white colour drains much more battery. if your a constant user of google (maybe even if its your homepage too) try use the black google version. save some battery.
i think personally for me 3g uses more battery than wifi. another factor is the network bars that drains battery if low as constantly hanging onto that low connection.
you should try flight mode and see how the battery fairs there so you can get a rough idea.
also come across an app called FreshNetwork which is a signal booster & finder. Android Market - 4.7 out of 5 Star overall rating! (9,152) as i speak, and it does work.. theres been times where ive had 1 bar connections but after using it i get like 3/4bars. so it helps ease the battery drain there as connection is much better.
hope its of some help guys!!
I know theres is some apps that drains battery, one tip is just deactive the auto-sync with your accounts, other thing, I want a batterystatus app, to know better that stuff.
And I will try this connection app, thanks

Man I even turned off my smart actions, so far I only turn on things when I am really using them. Auto-sync only with wifi!

Its something stock with the phone. I just got a second and it still does it. I haven't figured out what starts it. But once I kill it, like I said my battery life is fantastic.

hey first of all nice site secondly your tips are pretty much on the dot.. just thought of these apps people might find useful
autostarts - helps with disabling apps from auto starting when phone boots up (may be slightly speed up boot?) & also prevent certain app event triggers (maybe an app permission u aint happy with?)
FreshNetwork - helps locate better signals in which in return would improve battery life

In running processes, the vague media process. Auto starts and kills battery quickly.

Battery Life - HDX 7in

Anyone else having issues with battery life? I can go from 54% to 14% overnight, totally stock install with no added apps.
My HDX 8.9 only loses about 2% over night. Get a task killer and see what you can kill.
Fully recharged it, watched a movie for a few mins, then let it sit for four hours or so. It managed to go from 84% to 72%. For some reason while it does stay connected to my wifi, it keeps losing internet connectivity.
I got a taskkiller app and killed a few processes, I don't believe it should be necessary though. I wonder if I got a dud since no one else seems to be reporting the same issue.

Most likely you have a rouge app. Uninstall all unnecessary apps. if the problem persists then install gsam battery monitor and track the irritant. Uninstall annoyance and all is happy again

Totally stock install, to my knowledge I can't uninstall any of the preinstalled stuff. The battery issues persist though reboot so if it's a stock app with some issue there's not much I can do about it at this time.
On a possibly related note I've been having issues with internet connectivity, after my fire is inactive for some period of time it loses connection to the internet but stays connected to wifi. I have to toggle the wifi to get the data working again.
I finally decided to just get them to ship me a replacement, should hopefully solve all of my issues without me having to spend days trying to diagnose any problems with my limited access.

I have discovered that the location services can cause this exact issue due to constant polling. This issue is worsened with the additional use of the Google Android location services. Make sure you do not have the Location setting turned on in the "Wireless" tab of settings.
This issue only occurs intermittently, but when it does, it continues until location services are disabled & the device is restarted.

It wasn't enabled, I got my new kindle today though and just unboxed it. Hopefully it's resolved now.
Edit: Nope, same issue. When I got it, I turned it on, went though the tutorial, made sure location wasn't on, then turned off the screen and sat it on my desk. Six hours later I'm down 16%. Guess it's not as bad as before, but it's still not great. I wish amazon had better battery stats.

I have great battery life and idle time. Did you download anything at all? Did you change any settings?

Nope nothing, I can't think of any reason why two separate devices would act this way when no one else is having the same issue.
From when I edited my previous post to now, it's gone down 33%. (Which is a little over 2% per hour)
Edit: I installed better battery stats from an APK (didn't realize it would let me do this), so hopefully now I can see what's eating up the battery.
Edit 2: Something called msm_hsic_host is what's draining my battery. Apparently that has something to do with a cellular modem, which I find odd since my device is wifi only.
Edit 3: Installed DS Battery Saver, set it to slumber (If screen's off, data's off), problem solved.
