Charge only on powerfull fast chargers

[matdelahaye]

Hi, my phone charges only on fast chargers or powerfull USB ports on laptops.
I am sure that the cable is not a problem because it works perfectly with any chargers to charge my wife Samsung phone.
I am sure the “normal chargers” I used work perfectly because they work with other phones.

Hi and welcome to the forum.

It looks like you may not have read similar articles on charging issues Here are some links and ideas.

Meanwhile.

• How old is the phone
• You don’t provide any details on the chargers and cables you have tried.
• Did you check the battery dial *#*#66#*#* Service tests > Test Single > Battery status check

• It still could be the cable
  A fast charger may have been wired diagonally symmetrical so it will not matter which way the cable is inserted, but some haven’t
• If the charger and the cable are not both wired symmetrically then it will only work in one of four connections
• If there is a fault on the USB module on the phone, in that it also isn’t working in both directions then you only have a chance of 1 in eight if all there are not 'diagonally syymetricaly wired@

So can see you will requires some patience to work it out.

• A QC3 compliant charger that is confirmed to work both ways and USB C charging cable that is properly wired or not damaged. And then even if the phone USB can only charge in one direction it won’t matter.

You may want to clean the USB port on the phone where thing sometimes seem OK and other times not.

@anon9989719 , @Roms : I still can’t belive it, but it seems you were completely right!! What happened: Since I got frustrated, I ordered the bottom module for replacement. Having this as a backup plan I was not afraid to open up the modules and have a closer look inside. But I coudn’t find anything. Everthing seemed completly ok. But today afternoon I had the chance to use a strong illuminated magnifier and had a look at the inside of the bottom module again. And then I saw it: in the back of…

You don’t say which type of USB ports you are using on the computer USB A of USB C for example. If the USB A then check the inside to see if it is black or blue.

The black supply 5V with a maximum of 0.5A whilst the blue do 5V at 0.9V neither of which are ‘powerful’

There are no ‘normal’ chargers except the ones you are used to. There are a few protocols for charging for different makes

Unable to charge battery

Thanks for your help! Tried a fastboot and disassembled the bottom module. Contacts all looked clean but it has decided to start working again and kept working perfectly through 3 restarts and test battery drains. Hopefully it stays this way but I would be skeptical.
