Early this week phone gave message that my google cloud was full. I deleted all I felt safe deleting. I cleared caches on apps. However, I don't know if it is a coincidence but since getting the full message this week my battery went from charging 100% to 75% and this morning it only had charged over night to 72%. The phone is only a few months old. I disabled gmail notifications and I don't know how to disable email notifications. However, since I am turning phone off at night to charge that should not affect how much phone charges. Please help.
Having a good working phone is essential, and I'm sorry to hear about your problems with the device. Does your device have any water/physical damage? What's the Make/Model of your device? Have you made any changes to your charger or connection port?
