What To Do When Your Phone Does Not Turn On

The simplest reason causing a phone not turn on is a dead or drained battery. It happens when the phone gets immersed in water, dropped or allowed to fully drain the battery. The symptom is phone not turning on and not charging the battery. When that happens, make sure first that the battery is not just dead or drained before you send the phone to the service center for repair or before you buy a new battery. You may decide to send it right away only to find out the battery is simply dead/drained or buy a new battery only to find out the phone is dead.

The first thing you can do is borrow a friend’s known good battery similar to yours and try it in your phone. If the phone turns on, you are pretty sure your battery is dead or drained; otherwise, it's time to send it for repair.

When it is verified that the battery is dead or drained or if you don’t have someone to borrow from, try to revive the battery before you buy a new one. You just need a 9-volt battery, a 6-12 volt power supply, or a DC adaptor (6 or 9 volts) and a set of wires.

Connect the set of wires to the terminals of the 9-volt battery, power supply, or DC adaptor whichever is available.

Look for the polarity markings on your battery and connect the other ends of the wires to the battery terminals in the same polarity as the source above. The positive terminal is marked (+) while the negative is marked (-). Do this for 10 to 60 seconds or until the battery gets slightly warm. Do not use this procedure to fully charge the battery.

Insert the revived battery in your phone and charge it until it is fully charged. If the battery works well and does not discharge easily, you don't have to replace it.

In the event that it is not verified whether the phone still turns on or not using a known good battery and the battery is revived but the phone is still not charging the battery, the phone is dead; send it to the service center for repair.

Immerse it again in a bucket of water, and turn it on; while it is immersed. That is the only way to make it OK.

Hot water immersion tank. Electric Now there is chugging on coldfill after I turned off mains supply and ran hot water taps to drain off supply to fix a tap


If you turned the electric off before draining, Air gets into the system. It will sound funny untill all the trapped air gets "washed" out of the system. If the electric was left on when refilled, you may have a steam generating situation, causing the chugging.

phone is dead after drop into water


Remove the battery and allow the unit to dry thourouhly. Take a hair dryer to it if need be. Once dry, reinsert the battery. The unit should boot up. Water doesn't tend to cause any lasting damage. Pop (soda) or wine or anything that is sugary will fry the unit though. Good-luck.

i dropped my phone in water but icked it up right


Remove the battery and immerse both the phone and the battery in dry uncooked rice for three days. This is the only cheap way to dry everything out. After the three days put the battery back in the phone and it should be OK

My phone in salt water.


To anyone who drops their phone in salt water. Get the battery out immediately. When you get home or sooner if you can put the phone in something that will allow fresh water to immerse it entirely. Keep water running in the container for about 3 days continually flushing the phone. Now take all of the water out and fill the container with 99% Isopropyl Alcohol. Let the phone dry out for at least 2-weeks before trying a fully charged battery in it and turn it on. Should work and you have just saved yourself buying a new one. Then don't leave it in your pocket when you go to the beach, drop it in a Ferry Salt Water Toilet, etc., where it it is immersed in salt water. If it is most cell phone providers will refuse to even look at it from their tech depts. A Radio Tech/Inspector in Canada.
