    My recently purchased Galaxy Tab S 10.5 SM-T800 running Android 5.0.2 is demonstrating poor battery life with the usage data not explaining what is consuming about a third of the power.
    For example over the last 24h of very light usage max three hour,reading newspaper, web browsing, email, no streaming or downloading the stats are:

    61% used, screen 31%, Android System 3% Android OS 2%, Chrome 2%The Times 2%, everything else 1% or less, total; 42%, unaccounted for 19%.
    I am needing to charge every day, I previously had a third gen iPad which on similar usage would just about achieve three days between charges.

    As this model is generally regarded as having a good battery life I am puzzled.

    Put in case to Samsung support two days ago but no response yet.

    Welcome to Android Central! Battery usage is reported as an absolute (starting with Lollipop, I think), rather than relative. So that remaining battery percentage that is unaccounted for may just be every other process that uses 1% or less, all added up. You can install an app like GSam Battery Monitor to get more of a breakdown.

    It would also help to see more detailed battery stats. 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).
