What's going on

A Google Pixel 6 that keeps randomly restarting or getting stuck on the Google boot logo can be extremely frustrating. This issue usually stems from one of two categories: system-level software corruption (often following an Android system update or background app deadlock) or hardware failure (such as a sticking power switch, failing battery cells, or mainboard issues related to the Tensor chip).

Because the Pixel 6 relies heavily on integrated power management features and high peak power draw during camera processing and 5G networking, minor hardware drop-offs or software bugs can trigger an instant protective system reboot.

Symptoms people notice

• The Infinite Boot Loop: The phone shows the Google 'G' logo, loading bar, or boot animation, then blacks out and repeats the process indefinitely.
• Power Button Spasms: The power menu keeps popping up on screen on its own, or slight taps on the frame trigger a hard reset.
• High-Load Crashing: The phone functions normally while browsing the web, but immediately restarts when taking pictures, playing heavy games, or switching to 5G.
• Sudden Black Screen Reboots: No 'Restarting' text or animation appears; the display abruptly cuts out as if the battery was instantly disconnected.
• Thermal Triggers: The area around the top-center of the back glass feels uncharacteristically warm right before a restart occurs.

Likely causes

1. Software Update Glitches: Interruptions during background Android system updates or corrupted system cache files can cause system services to crash in an endless loop.
2. Stuck Physical Power Switch: Dirt, lint, or a slightly bent internal bracket can keep the power switch partially depressed, causing the phone to register continuous forced restarts.
3. Failing Battery: Lithium-ion batteries age over time. When the Pixel 6 requests a sudden spike in current, a degraded battery's voltage drops below the operational threshold, forcing a shutdown.
4. Third-Party App Interference: Apps with deep system permissions or unoptimized background services can crash Android's core framework.
5. Storage Depletion: When internal flash storage becomes nearly 100% full, the Android OS lacks the cache space required to function, leading to kernel panics.
6. Motherboard / Tensor Chip Stress: Micro-cracks in solder joints beneath the main processor or power ICs due to drops or flex can cut off power during expansion and contraction from heat.

Quick checks first

Before taking the device apart or considering hardware replacement, try these basic isolation checks:

• Remove the Case: A rigid or ill-fitting protective case can exert continuous pressure on the physical buttons.
• Clean the Switch: Use a brush and a small amount of 90%+ isopropyl alcohol around the power key edge to dissolve residue sticking the switch.
• Free Up Storage: If you can keep the device powered long enough, delete large video files or offload photos to clear space.
• Safe Mode Isolation: Booting into Safe Mode disables all downloaded apps. If the restarting stops immediately, you know the hardware is fine and a rogue app is responsible.

When it's a real repair

If factory resetting the Pixel 6 through Recovery Mode does not halt the continuous reboots, or if the phone restarts even while navigating the basic Fastboot text menu, you are dealing with a physical hardware failure.

• Battery Replacement: If the phone stays on consistently while plugged into power but restarts the moment it relies on internal power, the battery is the primary suspect.
• Power Button Flex Cable: If the physical button lacks a crisp tactile click or fires off commands unprompted, the internal flex cable assembly needs replacement.
• Motherboard Diagnostics: If the phone gets extremely hot quickly and reboots regardless of charger connection or firmware state, the logic board may have internal component damage.

If you have reviewed common system /problems and verified a hardware failure, hardware replacement is the next logical step.

DIY vs professional repair

Repairing a Pixel 6 at home is well within reach for DIYers with moderate experience. Replacing the screen or power button flex cable requires opening the phone from the front screen glass using heat, suction, and prying tools.

• DIY Pros: Replacing a degraded battery or power flex cable yourself costs significantly less than buying a new phone. You also maintain complete control over your personal data.
• DIY Risks: The OLED display on the Pixel 6 has thin flex cables and fragile edges. Excessive heat or improper prying can break the screen during disassembly.
• Professional Repair: If you aren't comfortable lifting glued display panels or working around fragile ribbon cables, sending your device to a mail-in repair service or consulting professional technicians via LML Experts can prevent accidental damage.

Next steps

1. Rule out Software: Attempt a force-restart, boot into Safe Mode, and if necessary, back up what you can and execute a full factory reset.
2. Isolate Hardware: Check if the phone behaves differently on battery power versus plugged into a slow USB charger.
3. Gather Tools: If opening the phone, ensure you have a heating pad or heat gun, suction cup, thin opening picks, T3/T4 Torx screwdrivers, and fresh display adhesive.
4. Follow a Guide: Visit our step-by-step repair /guides to learn the correct procedure for safely opening the Pixel 6 and replacing the internal battery or power button flex assembly.
