If you want a maximum of tutorials to become the king of the Motorola Razr, we invite you to consult the other tutorials in the category: Motorola Razr. Charging problem on Motorola Razr, what to do? Previous Charging problem on Moto E6 Plus, what to do? Next Charging problem on Oppo AX5s, what to do? If the problem persists after testing the solutions above, you may have defective Motorola Razr V3m. Check with your cell phone provider for replacement policies.
If you are in an area of poor service connection, your phone may not be able to send or receive messages. Verify that you are in an area of good service connection by looking at your service connection icon on your display or by contacting your service provider.
If you have having problems receiving or sending picture messages, your phone may need to be restarted. Restarting your phone may correct a temporary glitch. If you are having trouble finding your pictures to send to others, it may be because your phone is not reading your SIM Card. Make sure your sim card is correctly inserted into the phone. If you are not located in an area of service coverage, incoming calls may be redirected to voicemail. To turn off Call Forwarding, access your Voicemail settings.
Perhaps you turned down the volume in the past intentionally and forgot to reset the volume. To access your volume settings, press the volume buttons on the left side of your screen. Press the up button to make the volume louder volume higher.
If you are still unable to hear incoming calls after following the solutions above, your speaker may need to be replaced.
None of the suggestions above does anything. My mobile gave out an unknown ringtone from the back of the car. Thought nothing of it.
Later, it went crazy. Screen picture went into overdrive zapping up and down. You can still keep in touch with family and friends with this tiny gadget. Any system loses its charge, however. It would seem that one needs only to connect the device to its USB charging cable and wait for the process to finish.
What to do and how to resolve the issue in this situation? Thankfully, you should be able to solve the problem whatever the cause. You can tackle the issue even at home without assistance from maintenance services. If the smartphone is not exposed to moisture which is the source of charging problems , an external inspection of the device is recommended. The swelling of the case may signal a battery dysfunction as well.
So my Razr worked fine last night until I drained the battery normally. Went home to charge and it doesnt appear to accept the charge, will not boot probably cause it's still dead.
I've read on other forums that people get lights I have none its like its a paperweight except Motorola Device Manager appears when I plug it into my Mac and the buttons are responsive MasterGadgets Member. Make sure you are using the Motorola factory charger and cable. First off, "drained the battery" and "normally" don't belong in the same sentence If it does so, you run the risk of exactly what you are dealing with now. That coupled with the current the phone requires simply to boot can cause a battery that is "discharged" to become unresponsive.
Once the battery has been discharged below a certain current level the phone while trying to boot actually uses more current than the charger can supply while trying to also charge the battery.
This results in the battery never actually getting any charge or very little , and can remain in that state either indefinitely or for a very long time. There are many potential "solutions" to this dilemma, but the most effective is a Motorola Programming Cable, a special version of the USB cable that applies voltage directly across an otherwise unused pin on the USB cable and essentially bypasses the charging circuitry on the phone, instead supplying voltage directly to the phone and battery without any sort of monitoring or protection for the battery.
Using one of these cables can actually supply more current to the phone and battery than the phone itself is drawing, leaving an additional overflow that can then back-feed into the battery and slowly raise its current and voltage levels to a point where the normal charging circuitry can then resume normal charging. An alternate method - which by the way is both opening the phone case and voiding your warranty, is to strip the micro-usb cable end off a USB charging cable and jumper the red and black wires directly to the respective positive and negative terminals of the battery itself.
BOTH methods should ONLY be allowed to "jump-start" the battery for periods of 30 minutes at a time, and with an attempt to go back to the normal charging method between jump-start attempts. This all results from allowing the battery to drain to the point where the phone shuts itself off - a practice you should avoid at virtually all costs.
The reason this happens is that the metering circuitry and battery's actual State of Charge SOC , become, shall we say Characteristics unique to the Lithium Ion Polymer batteries and their discharge curve the rate at which the voltages and current available change while being used , make it difficult for the metering circuitry to actually know with any real accuracy how much "usable" power is left in a battery at any one time.
The charging circuitry uses two key levels which are set as "flags" during the charging and discharging process to essentially mark the "goal lines" on the field, but as with any field, there is an "end-zone", where the battery can either be "overcharged" or "deep-discharged".
This results in the real and suggested SOC levels to diverge and eventually be so far apart that the phone can misrepresent the levels and risk what you've experienced and all that you've read. This happens over time, due to the way we both use and charge our phones.
It just so happens that we are not in sync with the battery but instead we are sporadic with both our charging and discharging rates and times. This lack of uniformity "confuses" the meter and it begins "recognizing" various other SOC levels incorrectly as being the "Fully Charged", and "Discharged" SOC, and then using those incorrect level "flags" causes incorrect estimated remaining charge levels.
Also, as batteries age, their ability to hold a charge changes.
