Hello knowledgeable people!
I’ve been having problems with my battery draining very fast. Today it was fully charged at 6 a.m., and entirely drained by 09:30 a.m. The battery monitor looked like this:
The CPU has also been getting very hot.
So I looked on this great forum, and got the advice to install Better Battery Stats. I did that, but it didn’t work. My phone isn’t rooted (I’m not a real computer expert and just wanted an easily usable phone!) When I open BetterBatteryStats, I get this message:
I was able to enable Developer Options for USB debugging, and to install the ADB drivers (from https://forum.xda-developers.com/showthread.php?t=2588979). However, when I try to check it’s working by using “adb devices” at the command prompt, I get the response “List of devices attached”, and then nothing underneath. When I type “adb -d shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS”, it says “error: device not found”. I tried using the ADB driver installer recommended in this forum, and I got the result below:
Note that it appears to recognise my FP2, but without a name, and it says “ADB Driver already installed”. I tried updating the drivers using Device Manager, but I can’t get my FP2 to show up as an Android device. It shows up as below:
I don’t know what to do now - can anyone please help me? One thing I’m not sure about is if I’m doing the Command Prompt right. I’m just using the Windows Command Prompt, but I don’t know if I have to give the command from a certain place. I’ve tried doing it from within the C:\adb folder, but that didn’t work. According to https://www.howtogeek.com/125769/how-to-install-and-use-abd-the-android-debug-bridge-utility/, “you have to navigate to ADB’s folder and open a Command Prompt there whenever you want to use it” - but I’m not sure what that means.
Now I’m stuck! Any help would be much appreciated! Thanks
