    Okay, so I have a Samsung Galaxy S5 currently running OS version 6.0.1

    After the initial upgrade to the latest OS (about 1 month ago) I suddenly had drastically reduced battery life (down to 35% within 5 hours of unplugging with minimal use) and uninstalled 3rd party apps until it stopped.

    A few weeks later I slowly started reinstalling apps so I could gain some utility back on my phone and was unable to reproduce the issue.

    Then suddenly it started again, after uninstalling ALL 3rd party apps the battery was still draining incredibly rapidly, though not in safe mode.

    So I performed a factory reset, and slowly installed apps back, with all of my 3rd party apps installed I saw the battery drop to 83% in the 10 hours of my day (with average use) so I thought all was well.

    The VERY NEXT DAY however my battery dropped to 54% within 5 hours with very low usage. Today it's happening again with ZERO APPS OPEN and my phone dropping from 100% to 88% within an hour.

    Does anyone have ANY idea what this could be? I know Kies 3 told me that there had been an issue with the update and asked me to do an "emergency restore" which wouldn't work, and I was told I had to do the restore through Smart Switch.

    The restore option wasn't even available on Smart Switch however, so I'm not certain what it is I'm meant to do.

    Also Samsung customer support told me to take it to a Samsung service center, the closest one to me is nearly completely accross the country, so that's not an option.

    A couple of common culprits to look for are poor cell signal or a corrupt file on the SD card. Do you have an SD card inserted?

    It would help to see some 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).

    You might have to install GSam Battery Monitor if the stock battery graph doesn't show you cell signal strength.

    I've been dealing with the same issue with the same phone but remembering the time with my iphone 4 that needed to be charged 4 times a day, i think this is the biggest flaw ever for all phone manufacturers. I hope somebody could focus on this. Great apps and features are useless if your phone's battery is dead empty.

    Since upgrading to marshmallow, my phone is giving me fits:

    Same battery drain problem. my gorilla battery used to last a week, now it lasts 2-3 days
    poor signal, frequent loss of signal in the middle of Houston where signal strength is always excellent
    slow text delivery, partial text message deliveries, messages that are never deliverd
    calls missed, calls dropped, voice mail notifications that show up days late
    intermittent mic functionality and sometime no mic at all when receiving calls
    phone restarts itself, usually after ending a call
    sometimes I just find it turned itself off

    I chatted with Samsung and requested a link to revert the OS back to previous but they claimed this was not possible.

    Previously I was so satisfied with the phone. Now I hate it and cannot reliably use it for my business.

    Hello and welcome to Android Central cowboyessell!

    It is usually possible to downgrade your firmware by downloading and flashing it to your phone by carefully following the instructions and video contained in the links of #1.11 of 42 Galaxy S5 models - Dummies Guide.
