En "Servicios de localización" hay un ajuste de "Usar redes inalámbricas" - siempre que el ajuste está activado, obtengo constantes "nlpwakelocks" y la batería se agota mucho más rápido.
Sin embargo, veo que esto fue supuestamente arreglado por Google: http://www.androidpolice.com/2013/05/29/download-latest-google-play-store-4-1-10/ (mi versión es la 4.3.11) pero sigo teniendo los wakelocks en mi SGSIII.
¿El dispositivo solicita constantemente mi ubicación con esta opción activada, o mi conectividad de red cambia y el wakelock se activa cada vez (por ejemplo, las redes wifi y las torres de telefonía móvil entran y salen del rango)?
Estaría bien poder usar la opción, ya que aplicaciones como Google Now pueden saber dónde estoy, pero el gasto de batería hace que tenga que alternar cada vez y acordarme de apagarlo.
