In this article, “Dead phone power problem solution”, I will be showing you how to handle power related issues in mobile phones with respect to the circumstances under which these problems do occur with focus on possible causes and solutions.
What Is Power Problem?
A power problem is when a phone shuts down and is unable to power on. This situation is very annoying especially if you have important information or data you have not backed-up for one reason or the other!
Generally speaking, there are a lot of reasons why a phone could become dead, and thus necessitating a power solution to bring such dead phone back to normal functioning condition. So let me show you a list of possible causes and solution for power problem in mobile phones. They include and not limited to the following:

Possible Causes Of Power Problem In Mobile phones:
Production Fault: Production related faults are one out of many possible causes that necessitate dead phone power solution. This happens when you buy a smartphone only to find yourself going asking for warranty considerations. This is why companies should be flexible about this policy as users might feel cheated if they are not compensated accordingly.
Water Damage: This is when a phone experiences water splash or falls in to it or any other liquid that conducts electric current. Liquids, especially H20 (water) that conducts electricity will easily convey electrons that will eventually create a chemical reaction with the battery leading to explosions and damages to internal components on the phone’s PCB or the logic and power unit of the mobile phone. “25% of phones fixed at Cute Mobiletech are water damage related and are very challenging though good recovery successes have been recorded”!
Bad Phone Chargers: None-OEM chargers that falls short of standard specification are also one of the known causes of charging problems we have found to be part of the pack! Sometimes, it could be as a result of using a faulty charger which may still be an original one.
Faulty Components: The mobile phone is only mobile and handy, but is also like a PC. It is a system of its own kind and has so many parts that are inter-dependent. When one component is bad others could become affected and later may result in further complications that could temporarily or permanently shut down a phone! Components that may necessitate a dead phone power problem solution may include parts like. Shorted diode, bad fuse or (R22), Shorted capacitor, power IC (integrated circuit) or other big parts and so on.
Ageing Factor: Though bitter truth, no phone lives for ever! A phone will finally be laid to rest either at repair center or even while in custody of the owner, this is because the components that makes up the phone also have their life span limit which when reached will result in multiple issues.
Corrupt Firmware: The firmware are the program instructions that controls and give the phone a “life to live”. Therefore, when the firmware is corrupted by viruses or malicious apps, things could go bad resulting in a dead phone.
Wrong or Custom OS: Wrong or custom OS or firmware can result in dead phones. The number one cause of dead phone problem especially in Mediatek powered devices of Tecno, Gionee, Infinix, clone mediatek Samsung phones is when the wrong “preloader file” is flashed in to the lash memory.
Aside the list of possible causes of dead phone problem, there are others not in this list which we will cover when this article is subsequently updated. But let me also add that the CPU bad condition could result in power problem too if it has been badly affected.
Are There Possible Solutions To Phone Power Problem?
Frankly speaking, when it comes to solution to power problem, there is no one clear cut way to achieve this. The only way we know for now that is working for us is the “ancient path”, called “troubleshooting”, so if you are ready to fix that power problem, you will have to get ready for “shooting with your weapon”. Oh, don’t get it wrong, the weapon am talking about is your problem finding tool. That is why you can’t be a successful phone technician if you have not mastered the art of using the multi-meter and other machines meant for this purpose.
Some problems referred to as power problems are really not power problems per-say, but just a minor switch problem. A switch problem just needs one to fix or replace a damaged switch. There is no point saying a phone has power problem when it charges as you plug it to electricity using a good charger.
How To Troubleshoot Power Problems In Mobile Phones
Dead phone power problem is a common phenomenon. The main goal of troubleshooting a m obile phone is to proffer solution. To troubleshoot properly, ask the following questions as if you are a Medical Doctor attending to a patient:
Did the problem happen shortly after buying a new phone? Then go for claims of warranty. Due to faulty production, one could get a form of compensation.
Find out if it was caused by water or other liquid substances aside the ones that don’t conduct electric current. If it was caused by water as the case is mostly, locate the areas affected and clean up using a cleansing agent like ethanol-alcohol or menthylated spirit which dries up quickly. After being heated with the rework-station or sun to dry up, the phone should power on if it’s a minor case otherwise you will have to keep checking for short or open circuit or shorted components that could be responsible for that power problem using a multi-meter.
Find out if it was caused by a bad or faulty charger. To do this, use the multi-meter to check if the current the charger supplies is above 5.0v and 2500mAh (2.5Amps). If the current voltage on the meter is unstable, that’s a signal to watch. Look for the power diode close to the battery terminal area where you see points like VBat, BSI, GND and so on. Shorted power diode could cause power problem if affected by chargers or other causes. A normal power diode in many cases should allow current flow in one direction and not back and forth. If causes a short, replace the shorted diode or strike it out.
Find out if the phone was previously flashed: If you have found out that the phone went dead after a flash, simply get the right firmware and re-flash back. If you don’t know what flashing is all about, you can learn about software level repair here and that could help in resolving the problem.

I bricked my Tecno Camon C9 Mt6753 phone when trying to flash it with the SP Flash Tool. When l plug it to PC, it keeps on connecting and disconnecting and now it can’t be flashed any more, as the SP Flash Tool gives a Code 10 Error, saying: “DA didn’t send response data to SP Flash Tool” even when l have installed all the needed MediaTek USB and VCOM drivers.
How can l solve this problem? Please, help me.
Your phone is bricked and dead without PC detection, use Easy Jtag to restore boot and flash, it will work.

My Tecno pop 2 power just went off I was operating it and I have checked the battery and other possible things but it is not still on
Hi Ridwan, Sorry about your Tecno Pop2 Power issue. Consider the following actions:
1. Have u tried to flash it in that dead state? It can come alive if you do a flash properly.
2. You can also check for hardware solution checking for shorts or open circuits, check also the charging IC if it gets hot and replace properly, a faulty charging IC can also shutdown a phone.
3. You can also reheat the PCB and check again. Just try all this suggestions first……
I wanted to upgrade my infinix hot 5 android 7 to 8 so I did the flashing process using so flash tool, it was successful but won’t turn on even if I charge. What do I do?
Hi, I have an android which just stuck at ”Infinix powered by android” I’ve tried loading a new firmware but it won’t boot up. What do I do pls
1. Try another firmware with right ID, also make sure the boot and other display files are selected, you mght also want to flash the android file also.
2. Though this problem can also be a hardware issue too, probably your device might have been old, or cummulative falls might have weaken the firmness of ball points unde the PCB, so try reheating the RAM, ROM and CPU ICs. Goodluck Clifford….
Tecno l8lite is off
Give more details so we can help you.
Hello i have got an itel p32 which is not charging and also not turning on please can you assist me to fix it. i was about to flash it but could not do it because i did not have the drivers but after that its not charging or turning on.
Check for bad charging IC, for short or open circuit, also try to reheat CPU or Flash Memory.
Hy, I have itel p51 here just dead while in operation, after checking it doesn’t transmit any light to d panel including the board battery clip, please help me out.
Check battery power, reheat both flash and processor ICs
Hello Mr Musa, I have a itel A32F phone that is not powering on since it falls down. Pls i want u to give me guild lines on how I can troubleshoot nd solve the problems. Thank u sir
You complained of a dead phone after a hard fall on the ground, chances are that one of the chips had lost firm contact on the circuit board or that they are internally cracked, or that one or more components might have been stroked out. So observe carefully. Also try to reheat the IC chips on the PCB. Hope this helps.
pls my itel p12 just triped off on it own ,and it is not giving any atempt to come on nether charging or powering on ,,and i have checked the charging board ,i also serviced the phone board with fuel ,but the charging board is supplying current fine, so pleas i really need your help
Try reheating CPU and Memory Chip
also I have one techno k7 that is not coming up neither is it charging, but when I troubleshoot with multimeter I discovered that the reading of the positive area on the board is unstable, so expected voltage does not flow to the battery connector point. Pls kindly assist with the solution.
@Oladimeji, sorry about you ordeal, but you can also Check power IC, check for shorted diode and capacitors, check boost coil for open, check resistance of resistors to make sure they re ok…These might help!
thanks for you support, Pls I need techno w3 firmware upgraded version.
My tecno wx3 died on it own but i tried software even trouble shooting and yet to no avail now am lukin for d power ic to replace it i ned ur assistance 2 trace the power ic
Hi Ken, its under the gun shaped silver colour protective plate in between the power switch flakes on the left and the touch screen connector on the right. I have emailed you the PCB image. Try and find out if there is any shorted diode or capacitors etc. or open circuit. Check this post it might help in re-flashing too. Hope this helps.
