How To Fix LG V40 ThinQ Fast Battery Drain After Software Update
Problem: Hi there. Came across your post from last month about sudden battery drain on Android because I’m experiencing the same thing. I’m using an LG V40 Thinq and generally avoid updates for fear of something fucking up. Gave in a couple of days ago because I can’t clear the notification and am now up to date on security patches (was previously only up to October). That’s when the battery problem kicked in. The thing is, it’s only when using the Uber Driver app. I realise that is a big battery killer as it is, but until a few days ago I could do four hours and use 50 percent battery. Since the security patches four hours takes the whole thing. This is with the screen actually turned off most of the time, and with power saving mode on. Battery usage stats show me that it’s overwhelmingly Uber causing the problem, but I haven’t installed any updates for that app so I’m certain the issue has actually arisen from the security patches. I’m not so much looking for a solution from you, but just thought I would contribute my experience as you mentioned in the post that you’re still trying to get to the bottom of it.
Solution: Before performing any troubleshooting steps on the phone it’s best to make sure that it is running on the latest software version first. If an update is available then I suggest that you download and install it first. You should also make sure that the apps installed in your phone are the latest versions. You can check if an app update is available by going to the My Apps section of the Google Play Store.
Since this problem occurred right after a software update then this is most likely caused by a software glitch. Listed below are the recommended troubleshooting steps that you need to do to fix the problem.
Start the LG V40 ThinQ in Safe Mode
There are instances when app you downloaded can cause this particular problem as it is not properly optimized yet to run on the phone’s current software version. This usually happens when the said app uses a lot of processing power. To check if this is what’s happening right now try to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.
- With the screen on, press and hold the Power key.
- In the options menu that displays, press and hold Power off.
- When prompted to restart in Safe Mode, tap OK.
- After your device restarts, it displays Safe mode at the bottom of the screen.
If the issue does not occur in this mode then you should find out what app is causing the problem and uninstall it.
Wipe the cache partition of the LG V40 ThinQ
When the phone accumulates a lot of temporary system data this can usually lead to the data being corrupt. This then leads to issues with the way the phone works which is why it is a good idea to wipe the cache partition of the phone.
- From the Home screen, tap Settings.
- Tap the ‘General’ tab.
- Tap Storage > Internal storage.
- Wait for menu options to finish calculating.
- Tap Free up space.
- Tap Temporary files & raw files.
- Select the following options: Cached data, Clip tray temporary files, Raw files from camera
- Tap Delete – DELETE.
Check if the issue still occurs.
Factory reset the LG V40 ThinQ
One last troubleshooting step to consider is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before doing this procedure.
- Backup data on the internal memory.
- From the Home screen, Settings.
- Tap the ‘General’ tab.
- Tap Restart & reset.
- Tap Factory data reset.
- If desired, tap the Erase SD card checkbox.
- Tap RESET PHONE > Delete all > RESET.
You can also reset the phone using the hardware keys.
- Backup all data on the internal memory.
- Turn off the device.
- Press and hold the Power and Volume down buttons.
- When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
- When the ‘Delete all user data (including LG and carrier apps) and reset all settings’ message appears, use the Volume down button to highlight Yes.
- Press the Power button to reset the device
Once the reset is complete do not install any apps in your phone yet. Instead, try to check first if the issue persists.
In case the above steps fails to fix the problem then you should bring the phone to a service center and have it checked as this as there’s possibility that the battery might have to be replaced.
