What You'll Learn
Try holding the power button for 10 seconds or more
If your phone has entered the 'sleep of death' (SoD), you may need to hold the power button for 10 seconds or more to wake it up. This is a common issue that has been reported by many users, and it can be caused by various factors such as a Bluetooth bug or a cache issue.
When a phone enters SoD, it becomes unresponsive, and pressing the power button does not wake it up. In some cases, the phone may vibrate, indicating that the power menu has popped up, but the screen remains blank. In other cases, the phone may not react at all, even when plugged into a charger.
To wake your phone from SoD, try holding the power button for an extended period. Press and hold the power button for at least 10 seconds or more. On some devices, you may need to hold the power button for 20 seconds or even 30 seconds until the phone restarts.
It is important to note that this method may not work for all devices. If holding the power button for an extended period does not wake your phone, you may need to try other troubleshooting methods, such as performing a hard reboot or restoring your device. Additionally, make sure your device is charged as a dead battery could be the reason your phone is not turning on.

Plug your phone into a charger
If your phone has succumbed to the 'sleep of death', it may be worth plugging your phone into a charger. This is because the issue could be related to a depleted battery.
If your phone is not responding to your attempts to wake it up, try plugging it into a charger for a few minutes. This will allow the battery to charge up, and you can then try to turn it on again by holding down the power button. If your phone still does not respond, try holding down the power button for 30 seconds or more. This will force the phone to restart, and it may then start up as normal.
If your phone is still not responding, you could try a different charger and cable to ensure that the issue is not related to a faulty charging setup. If your phone still won't wake up, then the problem may be more serious than a simple battery drain.
It is worth noting that some users have reported that the 'sleep of death' issue can be caused by certain apps or updates. For example, one user reported that the problem started after they updated their device, while another user reported that the issue only occurred when using a specific app. Therefore, it may be worth checking if there are any known issues with the apps or updates you are using before assuming that the problem is related to the battery.

Remove the battery and put it back in
Removing and reinserting your phone's battery can be a simple fix for the sleep of death issue. Here's a detailed guide to walk you through the process:
Prepare the Necessary Tools
Before you begin, gather the required tools. You'll need a plastic tool, preferably a pry tool, and some isopropyl alcohol (IPA). The plastic tool should be soft to avoid damaging your phone. You can find these tools at electronics stores or online.
Access the Battery
Turn off your phone completely and remove the back cover. Be gentle to avoid damaging the cover or the phone itself. Once the cover is off, locate the battery. If your phone has a removable battery, it should be easily accessible.
Loosen the Adhesive
Use a few drops of IPA to loosen the adhesive under the battery. Tilt your phone around to allow the IPA to reach all the adhesive. Be careful not to use too much IPA, especially if your phone has holes in the chassis, to avoid staining the backlight.
Remove the Battery
Using the plastic pry tool, gently lift the battery out of the frame. Be patient and gentle during this step to avoid damaging the battery or the phone. The IPA should have softened the adhesive, making it easier to remove the battery without prying or forcing it.
Reinsert the Battery
After a few minutes, when the IPA has completely evaporated, you can reinsert the battery. Ensure the battery is securely connected and positioned correctly. Reattach the back cover of your phone.
Power On Your Phone
Finally, turn on your phone and observe if it wakes up from the sleep of death. If the issue persists, you may need to explore other troubleshooting methods or seek professional assistance.
