========================================

Hi,

I am facing an issue of battery drain after the latest update. On non gaming usage it takes around 4 hrs for the battery to reach from 80% to 20%. Android system is shown as the app that uses most of the battery. Please help with this issue. Device is also heating up slightly when browsing.

  • This started only after the latest update. It was fine before. No I have te recharge my phone every couple of hour.

    Doesn't look like there's anything wrong? With 2 hours play of COD and you're on 90hz screen refresh rate, you still have 50+ percent battery.

    How much battery you're expecting to use?

    You should try using denying apps from starting on start up too.

    The battery usage exceeds other phones for sure as number reason is you don't have the bloatware like other manufacturers.

  • No there is a change in the battery drain time. It's draining faster that how it was before the update. I use my phone always at 90hz but it never had this kind of battery issue. It lasted for quite sometime. But after the new update it's different. I can notice a constant depletion of battery percentage.

    Also, attaching an ss from accubattery. It shows 68% health. Do you know why that is?

    The 68% only shows your capcitiy usage over time. It would never be a true reflection on the health of the battery. Infact, AccuBattery causes battery drains due it stopping the phone from sleeping. Therefore, you should never rely on these so called battery monitor. An advice on what can be bad for your phone is if you keep charging and playing at the same time. This is where your phone is discharging and charging.

    I do note you have high usage on Google Play Services like me. I have been trying to get Google Play Services so it doesn't use alot of battery. For me, It came down from a recent update to Avast Anti Virus on the Anti Theft section where it was constantly using Locations.

    So let say if you didn't update, how much battery usage would you expect if you had the same amount of usage like now?

    It's impossible for accubattery to guess your capacity based on three charging cycles where you've only charged from 20 to 80%.

    Your battery drain issue may be caused by a lot of things. My guess is that one of your apps is keeping the system from entering deep sleep which means that the system is drawing as much power with the screen off as when it's on.

    First off, have you restarted your phone? A simple restart could fix the issue keeping your phone from sleeping.

    Second, go to system settings -> battery -> powermaster -> auto-start manager and prevent all the apps to auto start that you don't need a notification from.

    After this go to system settings -> advanced -> Mobile Manager -> Memory cleaner -> Turn on Super Clean mode -> enter app list and uncheck any app that you must get notifications from -> go back -> open recent apps overview and press clear all.

    Restart your phone again. 

    If none of the above works, then you need to factory reset your phone

  • I also have an ROG phone 2 and the most I use my phone is for 30 min - 1Hr instagram per day and a couple of hours of voice calling. and since the last update my phone's battery has started draining like water in a river.

    And the app that uses 90% of battery is "ANDROID SYSTEM". Never happened in an entire year. My phone easily went to 2 days of battery life before last update.
