Wont charge w375 with bq50 battery. plug in to charge orange battery light comes on , leave overnight phone wont switch on does not appear to have battery power.

You batteries may be dead. Any battery can only take so much charging before they quit on you. If your charger shows that it is charging and it still has not charged overnight, it is the battery. You can search on YouTube how to "recharge" Makita batteries when this happens. The Makita battery charge has built in diagnostics that will tell you if a battery is bad or not, but will not tell you if the battery no longer has the ability to charge.

Take it back to the people you bought it from and request a replacement.

try charging on a wall charger? im assuming you have a usb wall connector to match your computer charger like i do, also try it on different options besides mass storage.

Clean the charging port, remove battery, clean contacts between battery and phone, also be sure to use an original Motorola charger instead of one of those "universal" type chargers.

may be their is some problem with your battery or your phone software

It looks like battery is damaged... When plugged in to charger phone shouldn't power on. Try put it on charger when on and see if charging icon appear. (top right corner-battery status icon should change -insted of battery to charging.) Battery is fully charged after cca 4 hours, 80% after 2 hours.

Kevin you must try charging it with the wall-charger, if that doesn't works, try entering BL mode by pressing # and *, and then pull the trigger to turn it on.

It will tell you that battery is low, you can connect then the charger, pull the trigger again, it should start normally.

Take The Battery Out,Sim Card Out And Leave It All To Dry Somewhere Warm.

Good Luckk. :)

try charging with the flip open and watch what it says.
otherwise a new battery might be needed

You might have overcharged your battery and therefore it wont work. Also have you had a powersurge when it was plugged in? that could completely wipe out the charger and phone.go to a store to get help.
