Tips to Get the Most Out of Battery Life

To make the battery last through the day in your inexpensive smartphone:

•      Reduce Screen Brightness: Especially with AMOLED displays like those on Galaxy A35 or CMF Phone 2 Pro, keep it on adaptive brightness for power saving.

•      Activate Battery-Saving Modes: Most phones contained in this list have power-saving profiles available.

•      Close Background Apps: Background-running operations drain battery fast; keep a check on their settings.

•      Trade In With 247GreenGadgets: When the time comes to upgrade, sell your phone at 247greengadgets.co.uk/sell-to-us/ and use the sale proceeds towards the purchase of a new device.
