How long has the replacement battery been in the phone and what percentage is the phone at when it powers off? Also you say it happens early in the morning, do you leave your phone plugged in over night? I think it could still be a battery issue because on my old iphone 6s I had about a year ago, the battery was pretty toast and right before it would die it would sometimes freak out. (Sometimes with colors like green)

I have seen this also with ipods, I am pretty sure that the reason you are seeing different capacities is because of advancements in battery technology. Tldr: I think you can get increased capacity batteries

From the details that you have given the problem is either a blown head gasket or a blown head. THIS SHOULD BE REPAIRED IMMEDIATELY! This is caused by coolant getting into the cylinder and coolant being burned. That is why it is a very chemically smell and burns the eyes. I would suggest taking the vehicle to your local mechanic and they can do the repair. This repair should only be done by someone that knows what he is doing.

F25 is a communication error between the mcu(motor control unit) and the main board . it could be alot of things as quoted from @oldturkey03 : If the control is unable to properly detect motor speed, the machine shuts down. If a failure occurs during high-speed spin, the door unlocks after 3 Minutes. Possible Causes/Procedure 1. Verify the shipping system including shipping bolts, spacers and the power cord are removed. 2. Unplug washer or disconnect power. 3. Check drive motor tachometer resistance. It should be approx. 115 ohms. 4. Check wire harness connections between the drive motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU). 5. Plug in washer or reconnect power. 6. Check the MCU by looking for operations of the drive motor. 7. Check the drive motor for powered rotations. If everything checks out okay, you should think about replacing the MCU since it may not read your motor correctly. Download the service manual from the bottom of this page.

If it is gas then the clutch may be worn out or if its the kind that turn off every time you stop it may just be old. If it is electric then it may just be getting old

The shortcut should be in the Keyboard Control Panel in the tab settings Shortcuts clicking on the Keyboard section. If it is not in there it might not be disable-able

If you have tried all of those then maybe the spark plug wires or electrical systems are not making good contact. I would clean the contacts of the wires and if you have a multimeter use it to make sure the wires are working properly.

The SIM is probably fried.

The carbs float is probably clogged.

The mother board might be fried or the power supply is fried in some way.
