    This is the best battery saver than all that i tested if you put into standby mode it saves a lot of battery before it was like 100-80 but now its like 100-98. Totally Recommended :)

    Charged my phone to 100% last night and took it off charge at about 11pm. At 7am this morning, battery percentage was an amazing 95%. It had dropped only 5% over night! I love this.
