If you must leave bluetooth enabled on your phone, this is the battery to get. Bluetooth is a huge drain on the OEM battery that comes with the Moto Q and the OEM battery can't even chug out an entire day. This bad boy makes it through the entire day and night with bluetooth on and then some although I still throw it on the charger that night (if bluetooth was enabled). If you disable bluetooth you can get a weekend of casual use before it needs recharging. Your mileage may vary, but I did not have any problems with this purchase and it solved my problems with the Q quite nicely.
