    Ok, so what is basically happening is that the battery of my Samsung Galaxy s4.
    I have already attempted to optimize everything that I possibly could but it still only gets the battery to about 5 hours.
    In a few days, I will go take it into the Samsung shop but they will probably wipe it and give me a new battery, so I am first asking here.
    Recently I have checked some forums and read that it could potentially be caused by the SD card, I presume this is because of the information constantly being sent between the two storages. I bought the SD card on amazon.
    So what should I do? re-format the SD? get a different SD? not use the SD?, etc

    Thanks in advance for any help!

    Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

    1. The main Settings>Battery screen.
    2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
    3. The Screen category (to see total Screen On time).
    4. The Cell Standby category, if present (to see Time Without Signal).


    You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.
