Resposta para "Why is my battery draining really fast?"To help save the battery life, try closing any running background applications in the running apps menu. You can also turn off or reduce your use of Wifi, GPS, and Bluetooth. Also, the screen’s brightness can drain the battery life too, so try dimming the brightness. If these suggestions do not work, you may need to replace the battery. You can check out this troubleshooting page for more help.
