I barely touch my phone during the day, I'm not connected to any data or WI-fi but the battery still needs charging every day and a half or so. I turn it to airplane mode and night and turn off all of the notification stuff. My husband is adamant that I cannot replace the battery, even though I was able to purchase one online. Also, can anyone suggest any apps that I could use to maybe help with watching the battery power? Any help regarding this would be appreciated. Thanks so much.
