Revision to Samsung Galaxy S20 Will Not Turn On
| == Cause 1: Battery Discharged == | |
| - | === Solution: Charge Your Phone === |
| - | |
| It’s a well known fact that phones need power from the battery to operate. While usually your phone will alert you to a low battery with a prompt on the screen when you attempt to turn it on, if the battery level drops low enough there may not be enough juice to power the screen—even briefly. An excessively low battery may be causing your phone to remain unresponsive when holding the power button. To fix the issue, simply charge your phone for at least 10 minutes before attempting to turn the phone back on. | |
| == Cause 2: Firmware Fault == | |
| - | |
| - | === Solution: Force Restart === |
| If the problem with your phone seems to have occurred for no reason (i.e. you didn’t drop it or expose it to extreme conditions), it’s likely due to a problem with the phone’s software.

| == Cause 3: Bad Battery == | |
| - | |
| - | === Solution: Replace Your Battery === |
| Lithium Ion batteries like the one found in your Galaxy S20 are only rated for around 400-500 charge cycles before the battery capacity degrades to 80%. For most regular users, this will happen at the 1-1.5 year mark, at which the user will notice that their battery holds less charge and takes longer to reach a full charge. However, at around 50-60% capacity, the battery will start to fail to hold a useful charge and may even struggle with providing adequate power to handle the performance of the phone. If you’ve been using your phone for 2-3+ years and have amassed a thousand or more charge cycles, your phone may have trouble starting the hardware up, even when fully charged. | |
| == Cause 4: Screwed-Up Screen == | |
| - | === Solution: Replace Your Screen === |
| - | |
| The screen of the phone is responsible for displaying the user interface, and because it controls most of the input/output for the phone, a faulty screen may be mistaken for the phone not turning on. | |
| == Cause 5: Motherboard Malfunction == | |
| - | |
| - | === Solution: Replace Motherboard === |
| If none of the above solutions was able to turn your Samsung Galaxy S20 back on, the issue may be with the main circuit board of the phone. The motherboard controls most of the phone’s functionality, handling input sent in from the screen and buttons and processing it to produce the desired outcome. Also contained on the motherboard are the phone’s Qualcomm Snapdragon 865 SoC (system-on-a-chip), RAM module, flash storage, and 5G modem, among [guide|131607|several other chips|stepid=259200]. | |
