[Q] What's Causing My Battery Drain?

---

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
