Redmi note 4 does not turn on

Hi Sheetal Chauhan,

As you know water and electronics and electricity are not a good mix.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion doesn’t stop until it has been cleaned away

Rice does nothing to fix the problems caused by corrosion

Don't Put Your Device in Rice. Here's Why

First do not turn on your phone and then you need to remove the battery as soon as possible from the phone to minimize further damage.

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ (available at electronics parts stores) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do use it, check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link to a video that shows how to dis-assemble the phone so that it can be cleaned properly, which may be of some help

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.

Hello! I came on this site looking answer for similar problem but I also faced the one, dropping in water, you will have to get it fixed in store. Some parts were damaged as they were not water proof this was the case in mine.
