    hello all,

    within the past 2 weeks, my z2 has had battery performance issues.
    I use to have a fully charged battery at 10 pm before I went to sleep, wake up at 445am and at 98-96 full,
    would be able to get to work ( 6 am ) and have the phone still good and have power unitl about 2-3 pm when it would hit 35%. now i wake up at 88%, by time I get to work 80% now today its 950 am and at 67%
    I have tried to reboot , shut down and rebooted, havent added any apps, dont know where to start to look for an issue.

    thanks,
    dave

    Clear cache in storage and remove unwanted apps which are using more battery. Try to charge phone without any use. Try to off mobile data and wifi if no need. Charge phone upto 90% only and use it.

    When you go into Settings > Battery what does all the usage data look like? What processes or apps are using the most battery?

    The Clear Cache option was removed from the Recovery menu with Oreo 8.0.

    Which apps are the highest battery users?

    But which apps specifically are using that battery? You can see the list of apps on that same screen your are reading. Which apps are using battery?

    Take a Screen Shot of your Battery Usage and Post it

    On the main Battery Settings screen where you are gathering the usage data from & posting here.....scroll down. There you can see all the apps using battery. Like this screenshot.

    Moto app launcher is the stock Launcher. That's your "home screen" and all the home screen functionality. That seems like normal usage. Why is your Camera using battery and screen on time? What camera do you have installed?

    Also, apps that are not currently Optimized might be that way for a reason. Some apps will not work well if optimized, the they stop working when the screen has been off for a while. For example, if you wear a smart watch you don't want to optimize the Wear OS app or the phone & watch could stop communicating.

    so verizon replaced my phone with a refurbished unit.
    the battery life is back to be great
    even opted for the moto mod battery pack for camping weekends.
    something went wrong with the battery from what the store told me.

    thanks

    Good to hear that Verizon helped with a warranty replacement and things are working better.
