I have this iphone 7 and it heats up even not in use. As it in stand by mode. It charge normally. It also shuts down or restarts sometimes randomly even before battery is zero. It heats up during use and while not in use. Secondly, battery drains fastly when not in use followed by heating as mentioned above.
Is this a good question?

The problem may be because of a faulty/heavily degraded battery. You may need a replacement battery.

This sounds like a short on one of the main power rails. You will need to check the PP_BATT_VCC and the PP_VDD_MAIN line with a multimeter. Is this the same phone that has the cell problems?

Yes, this is the same phone with cellular issue. There is ic problem also in board. Signal ic needs to be replaced with death approval. But looks like there is separate battery issue going on with it. I'm not sure wether the board issue is causing battery drain and heat OR battery is separate issue. I think i should only get the battery replaced. What's your opinion?
@zain46663 The signal IC you mentioned is called the Baseband CPU and it cannot be replaced as it is married to the CPU. The Baseband CPU needs to be removed and re-balled then soldered back on. This is not an easy repair and honestly I wouldn’t be spending any money on a battery before you find the short on the board which would have occurred with the prior repair attempt.
@imicrosoldering thnx man. Appreciate your answers. I'll keep your points in mind. I will get it checked by someone.

Hi M. Zain Ul Abidin,
As @pod_boi has already suggested, the chances are good you simply need a new battery. On the iPhone 7 this is a reasonably straight-forward repair, one that you can probably do yourself with the help of the iFixit battery replacement guide. My suggestion would be to buy the iFixit battery with the Fix Kit that includes everything you need to do the job right, including display and battery adhesives, along with the necessary tools.

That’s expensive for I iPhone 7 battery. Our shop fits them for £20 with a 12 month warranty.
That's parts and labor, @strongbow? Not bad, I'd go for that deal myself.
Of course, I pointed @zain46663 to the version that comes with the Fix Kit; if he doesn't need the tools and screen adhesive the prices drops to $19.99 USD, or about £17.77 in pounds sterling.
@dadibrokeit yes, supplied and fitted.
