Sometimes my PS4 would get hot. The fans would speed up during game-play to cool down the PS. The system is autonomous, if the internal CPU detects temperature going over certain Limit, it would boost up the fans to compensate.
So far I haven't had my fans turned on while the PS is resting no, BUT the PS would dial up the speed when i set it to rest, sometimes have it going for few minutes before calming down.
As said before, it depends on the temperature. In my experience, I'd play a game with low speed, then in the middle of the game, it would go to mid-high. Then when i set it to turn off it would go to high for few minutes.
Play your games and don't bother about the cooling down. The system is smart enough to know if it needs to have the fans on or off at any given time.
In conclusion its worth mentioning that the optimal working temperature for a system (CPU. GPU) is not something that me and you might consider normal. 60 Degrees is completely in the realm of good temperatures for a CPU to work at, and is even preferable than say 20 as that how CPUs work better and is not worth going into detail right now.
It's a change from SRAM (Static Random Access Memory) to FRAM (Ferroelectric RAM), EEPROM (Electrically Erasable Programmable Read-Only Memory), or other non-volatile memory (keeps its data even when it's not powered).
SRAM requires an active electric current to keep its memory active (called volatile memory). However, FRAM, NAND, and EEPROM memory are examples of non-volatile memory storage and do not require constant power to store their data. Improvements in non-volatile memory allowed the change to happen en-mass. The use of volatile memory for save states was greatest during the SNES/GB/GBC/Genesis/GameGear era, phased out during the N64/GBA/32X/Nomad era, and I don't think a single DS game used them. Gamecube obviously didn't.
The battery is still used for the RTC (Real Time Clock), which requires power to keep its clock source (an internal or external crystal oscillator) running, and updating of its time registers. Funny enough, modern computers still do this for their clock.
Maybe. Here's the thing. Pokemon games are constantly counterfeited. Fakes are common. Sometimes it's hard to tell. This site has very high res pictures of (supposedly) real cartridges.
For example, the LeafGreen has a Macronix MX29L010TC EEPROM. No Battery.
Yet Sapphire has the same EEPROM, but with battery.
Of course, Leaf Green and Fire Red do not use a RTC, hence the lack of a battery (while also causing certain things not to happen correctly, or taking longer, like berries growing).

The OP's solution - originally posted in the comments:
The only way for the battery to resume time is to restart the game.
As much as I hated to do it, I restarted the game and now everything is working properly.
