Steps to follow to save a wet smartphone
The constant use of mobile devices, their small size, or their transport in poorly protected spaces such as pockets or bags, make them especially susceptible to getting wet by accident. We are not referring to a slight accidental splash, but to falling into a sink or bathtub, or being the victim of rain.
If the phone is connected to the charger with electricity, if it is being charged in a bathroom or kitchen for example, do not try to remove it from the water without unplugging the charger. If this is not possible, cut off the electrical path before removing the phone or tablet from the water. Do not press any key or try to see if it works, and if possible, open the case to access the battery and remove it immediately. If it is not possible to remove the battery (iPhone case) and, if the phone is turned on, turn it off immediately.
If the phone or tablet is in a case or casing, remove it and proceed to remove any possible SD and SIM cards it may have. Do not disassemble the device.
Proceed with drying, but do not use a dryer even in cold mode. If you have a vacuum cleaner, you can try to vacuum the observable liquid.
Once dry, introduce the device into a desiccant. Spare parts for “dry ball” type dehumidifiers or “cat litter” usually made of silica gel are appropriate materials, and are easy to find in supermarkets. If you do not have this material, or while you are accessing it, you can insert the phone into rice. Leave the device covered by the desiccant (or the rice in your case) for at least 24 hours. Although silica gel is not toxic, it can sometimes come with an added product that may be, so we must always be extremely careful when handling this or any other chemical.
Put the appliance in a bowl of raw rice and leave it overnight, since the rice absorbs the moisture that exists inside the device. However, it is more advisable to use a more efficient substance such as desiccant. Do not switch on the appliance for a period of 24 hours. After the drying time, connect the phone completely dry to the charger without battery (if possible) and, if it works, put the battery in and check without connection to the charger.
When in doubt, it is recommended to take the phone to an authorized dealer, explain the case and the actions carried out for drying. One last possible solution before giving up the mobile is to open it and spray it with an electronic circuit cleaning spray. It is not a magic solution, but sometimes it can work.
Beware of condensation
A source of possible damage is caused by corrosion of the device. Condensation can cause the accumulation of water internally if we use the mobile phone in very humid environments, which will lead to fairly serious breakdowns.
We must not rule out, in the case of being aware of the possibility of condensation (due to prolonged exposure of our mobile to this type of conditions), carrying out preventive drying, leaving the mobile 24 hours covered with desiccant material as explained in the previous paragraph always remembering to remove the battery (if our device allows it) before covering it with the desiccant material.
Faults in the battery or in the charging elements
One of the common reasons for malfunctions in a mobile device is the battery. Unforeseen restarts, the device does not start, the battery does not charge despite being connected, the battery life is very short, etc., these are some of the symptoms that may lead us to think of a battery failure.
Before replacing a battery because it does not charge the mobile, it is advisable to connect it directly with the USB cable to a computer, without using the charging charger, since in the case of a completely exhausted battery the device may take a long time to react. If after 3 or 4 hours the phone continues without turning on we will proceed to inspect the battery.
- Remove the battery from our terminal, if the model allows it, otherwise go to the technical service. If the battery shows deformations we must replace it ( without forgetting to recycle the defective battery ). If not, check the contacts of the mobile to ensure that they are not bent or broken and check that there are no gaps that prevent proper contact.
- If the battery does not appear to have problems and everything is correct, test the battery in another mobile or our mobile with another battery.
- If the battery does not charge in another mobile phone even using a different charger, it must be replaced.
Is it possible to extend the daily life of the batteries?
The use of mobile devices to carry out various functions throughout the day (work, relationships, leisure, etc.) requires us to consume the battery intensively.
Not all applications or all styles of use consume the same, so we have to expect very different battery life. However, the need to extend the use of the battery will always be present, so it is worth knowing some measures that can extend the battery life of our mobile. We propose the following:
- Do not activate vibration unless you need to mute the phone.
- Turn off the Bluetooh, start it only when necessary.
- Turn off keyboard sound.
- Set the display backlight as low as possible. In any case, adjust the energy saving mode and, if you do not want to decide manually the brightness of the screen, point to Auto to adjust it.
- It is highly recommended to charge the battery when it has reached 20% of its capacity. When the charger is plugged in, let the battery fill up completely.
- Avoid extreme temperatures (high or low), direct sun or the proximity of heating appliances.
- Always update your device to the latest available version of the system and keep your applications updated.
- Consider disabling the automatic synchronization of some features such as social networks or email if you do not need them.
- Avoid leaving games or applications started and, if in doubt, restart the phone.
- Don’t abuse informative widgets : weather, news, etc. Consider accessing them through shortcuts.
- If the WIFI connection is not used, disable it.
- If the GPS is not used, disable it.
