Motorola Droid Razr :: Battery Use While On Charger?
Nov 7, 2012
So I was on a road trip today and when I plugged in the phone in the car dock I had full battery. Then I turned on navigation and slacker radio. About an hour travel the battery started to charge according to the battery icon. My question is, why did the battery discharge while on external power? Does the factory charger not have enough capacity to charge the phone while being used? If so something is wrong with the whole designe of the charging system.

When I'm using my charger to charge my phone (as opposed to plugging it in charged), the charger gets really hot (~160 degrees fahrenheit), it makes a quiet hissing noise, and if I smell the USB ports, I can smell "the short-circuit smell" faintly. I'm wondering if this is normal, as the charger has been doing this since I bought my phone. (It's the charger they provided to me with the phone).

Is there any information on the max current draw for charging the Droid Razr? Both wall chargers I have output 750ma but I believe my car charger only puts out 700ma. Will charging the phone on a charger with too low current output damage the phone? Will it damage the charger? Or is the phone smart enough to throttle the current usage to what's available? I'm assuming the latter is the case since I can't find any warning on charging current. Will a higher output charger (say 1A or 2A) charge the phone faster? Will it affect the longevity of the battery (slow vs fast charge)?

In the user guide for the Droid RAZR dock (part # 89525N ), there is a split audio/charger usb cable. This cable also shows in several catalog photos for the car dock.I purchased the car dock from a Verizon (official) store, but only got a straight audio cable. what the part number for this cable is, and (b) where can I order it?

I want the display to stay on while connected to my 12VDC charger while in the car. I don't have an official Moto car dock. I have tried using Smart Actions but the only options seem to be changing the screen timeout option to a maximum of staying on for 10 minutes. I've tired many variations using Tasker and still no joy.

My car dock charger stopped charging my RAZR but works on my wife's HTC but my older Moto vehicle charger still works. It also seems as if it takes a very long time to chage the battery even on my original RAZR home charger.

Does anyone have the part number or output rating of the charger that ships with the Razr Maxx? I have a box of Motorola chargers but I think I grabbed one for a headset as my phone seems to be charging slowly.

When I look at the battery use in Settings/Battery Information it shows items such as WIFI at 4+% ( WIFI not even on) or a game I played (today Jewels Star at 25% - only was to make this one disappear is to uninstall the program, this is true with any game I play). My question is, is this information about what WAS running or information on what IS running. or both.

I can leave my phone on charge for hours and it will only charge to 90%. It will not go to 100%.

Since I updated my RAZR with ICS, it doesn't seem to really go to sleep.It's using a ton of battery power and I've already adjusted my display down to 30 seconds.

My battery lasts good most of the day but when it gets to 50% it will drop to 20% in about 2 minutes. Do I have a bad battery or is it just out of calibration. It has did this twice in the last week. I have not run it til it shuts off so I don't know how long it would last from 20% to being out of juice.

Yesterday I checked my battery usage and Moto cast was at 20%! I did not transfer any files between the PC and the phone and when I do, I still do it by copying and pasting. I did however find some Amazon downloads that were in the phone's internal memory and transfered them to the SD card. When I used "My Files" to move those files, I first used the "move" command which did not seem to do anything. Did this activate Motocast? I eventually moved them by using copy and then paste on the phone. Here's what I got in the battery manager right now. I'm at 90%

I'm currently having an issue with the Droid Razr M where it begins rebooting when the battery is low. After the phone boots back up, it immidiatly reboots again and will continue doing this forever. The only solution I've found thus far is to boot into safe mode and uninstall the 3rd party launcher (doesn't matter which one). This will allow the phone to be booted into normal mode again. However, regadarless of if a launcher is installed or not, the phone will begin rebooting again the next time the power gets low.

I have the option selected, Options>Sound>. to notify when the battery is fully charged.I'm not getting a sound, a blinking LED, or anything in the status bar stating that the battery is charged as I did with GB. The only way I know it's charged is by going into options and checking the battery status under device options.The only change I have that I think could be affecting it is that I have the screen lock function turned off.

One of the things the custom ROM makers all do is to implement a change to the stock system to enable the battery status to be reported in 1% increments, rather than 10% as at present. They also change the battery icon set so that the correct % charge remaining is displayed in the battery in the status bar.Why doesn't Moto implement this change in their next update? It would be a welcome change to every user, and it might slightly mollify those calling for an unlocked bootloader. (Though after the glitches I've seen in this update I'm on the unlock-the-bootloader side myself.)

Android OS keeps using 35 to 45% of the battery. My droid, DroidX, and Thunderbolt never used that much. This is the culprit for such a horrible battery life. I have the wifi off now and gps off when im not using it and it still has issues holding the charge for awhile. I wish I could delete the motocast account to see if that is the issue but I cant. Could it be smart actions that is causing the thing to continually search for triggers and wear battery? Or is it motocast? I don't use motocast or the stock music app ever and my mac is off too. So I want to know why the android OS is eating this battery up. Is there some fix on the way? I deleted every app and it still will show that android OS as the main battery hog by a lot. I only have gmail I don't have facebook updating anything so I really don't know what's going on.. I do know that when i used cpu spy the 300 megahertz was used for longer than the phone was in deep sleep. So something is using the CPU in that range non stop it seems.

I was in Europe a few weeks ago with my Verizon RAZR HD running ICS. In the US on VZW's network I can easily get through the day with greater than 50% battery, While in Europe, in Germany, Switzerland and the UK, the battery was draining at a tremendous rate and would be depleted in about 4hrs. Nothing changed as far as usage, app's or other obvious things on my end to cause the issue. Any idea on what it could be? Prior 3G phones didn't suffer from this while roaming in these same countries.

I met a guy this past week who used an iPhone 4/4S. He had a protective case with an integrated battery pack. Does the Razr have any accessories like this anywhere? I've seen products that are like exernal cubes or battery packs, but not cases (which I'd really prefer).

I haven't been using my RAZR Maxx so it's been sitting on my shelf powered down. Generally when I have a phone not powered, the battery will stay charged for weeks. On this phone, it is draining to zero in days from a full charge. That doesn't seem normal.

I own a Droid Razr MAXX that I purchased in the June timeframe, so it is still essentially new. My phone was updated to ICS when Verizon pushed the update out to everyone a few weeks back. Initially, I was excited to be getting the update to help improve phone performance and functionality. Unfortunately, this has not been my experience.
Over the past few weeks, I have noticed that my phone signal strength has diminished. Since I work a desk job, I sit in pretty much the same exact location each day and it is easy to notice signal strength. Before ICS, I usually had a 4G connection with 3-4 bars. Now, my phone fluctuates between struggling to connect to 4G and eventually connecting to 3G with 1-2, maybe 3 bars. In fact, the signal icon frequently changes from blue bars to white (I'm not sure what it means, but it probably isn't good). The phone seems to run slower and my apps frequently crash a few times per day. In addition, my phone seems to be using more battery now too. Before ICS, I could work a full day and still have 70% battery remaining. Now, I'm lucky to have 40-50%.
I haven't added any new apps, but have a few more .MP3 songs saved to my SD card. In addition, I don't believe there are local issues with a cell tower going down, etc.

I bought the extended battery - P893. It was fully charged when conneected to my phone. My phone had @ 10% batter life left. The extended charger bumped the charge up to 60% with no extraneous processes running. The delivered cusomt smart action for the extended battery was activated. That seemed a bit low given the product description and mention on the boards of delivery two full charges. I fully recharged the battery. When my phone was depleted to 20% I connected the extended battery again. The charge was brought up to 60%. Their was no charge left in the battery extender.

In the past 3 days this % of battery usage has gone up dramatically. Close to 50% on 3 different charge cycles. No new apps installed and nothing new under running apps that I'd normally have to manually kill. (I've disabled most all of what I can of bloatware)

If you use your RAZR / RAZR MAXX for tethering, or as a hotspot, for connecting a WiFi-only tablet or laptop PC wirelessly to the Internet, how is it affecting your phone's battery power consumption?
