The cell phone's out of charge, the phone repairer says the battery has to be replaced, but i tried three moves to save my life。
It's not broken, it's locked by the battery management system. It's like people fainting from hunger and having to feed sugar to wake up。
I left the iphone in the drawer for two months last month, and i pulled a power button, black. The plugs don't work. They don't flash light. Asking the shopkeeper, zhang mouth said, “battery scraps, new 280”. I didn't pay for it, i went home and looked at it, and it was quite common -- it wasn't the battery that couldn't work, it was the voltage that fell too low, the bms automatically cut off, unlike the switch off, it was a “false death”。
Checked the universal meter, battery voltage was 2. 68 v. The instructions state that lithium batteries are below 3. 3 v, and bms cuts off access. It's not welding, it's not the core. It's just "sleeping too heavy" and it needs a little push。
I'll try the simplest thing: pull out all the wires and use the original wire to connect to usb. The u. S. B. Output is steady, power is small, it won't break. After two hours of waiting, the cell phone hit and the screen flashed out the apple sign, but i know it moved. Then the original charger was replaced, and it was loaded to 15% in 40 minutes。
If your cell phone battery can be removed, or has been removed, the voltage is particularly low (e. G. 2. 2v), you need to use some tools. My friend used a transhipment power source with 3. 0 v voltage and a limit of 500 ma, and the red clamp hit positive, black clamp hit negative, not exceeding 10 seconds at a time, three times, and the voltage jumped from 2. 1 v to 3. 4 v. He didn't have the guts to weld himself, just a little bit, like ring the doorbell, wait for it to respond。
Don't be blind. I saw someone welding the old chargers straight up and moving to 9v, and the battery burned and smoked and threw them in the water basin. This really happened when there was news in 2025, a young man tried back and forth three times, a battery drum bag, a "sniff" when charged, and a cell phone cap broke. Over five seconds in reverse, the internal structure of lithium power is irreversibly damaged and will not last another week。
There are also people who put batteries in the freezer for a night and say, "low temperature activates." wrong. It has been measured that charges below 5°c, bms recognition code, voltage jump, 20% reduction in charge for half an hour, are easy to crystallize and have a direct folding of life. Temperature is much more important than electricity -- i deliberately reduced it to 37% before i put it in the drawer, and now i think it really saved it。
Now i'm used to it: mobile phones don't play very often, they're taken out every six weeks, and the plugs are filled to 50 per cent. It's not full or light, it's stuck in the middle. Master says it's called "awakening bms self-censorship" and it's just like people's regular activity. The chips are not rigid and logical。
And don't believe the old saying, "the discharge to zero is full." lithium batteries do not have memory effects. They are pressured repeatedly to the end. They accelerate ageing. I used it every day to turn it off, and then three months later, i shrunk from a day and a half to five hours, so i changed the battery to realize that i starved it every day。
Not after activation. I tested three days in a row: 20 minutes at a time when the voltage did not rise by 3. 6 v; three times at a time, the amount of electricity fell evenly. For the first time, it fell hard, for the second time it was steady, for the third time it was basically normal — numbers kept up with the actual hours of use, and then it worked。
If you're done with the black screen, or you're gonna burn your hands for a few minutes, don't push it. My neighbor tried hard for four days, smelled the last charge and stopped. Bms chips are burned, or the core is too resistant, and it is right to change batteries. It's right to save money, but it's not worth it for security。
Last time i went to the cell phone store, i saw three “fast to death” old batteries on the counter, with the label “customs refuse to activate and change directly”. The master said that two pieces could actually be saved, one voltage 3. 1v and one 3. 25v, which was a little push. They're lazy, customers don't understand, and they're all in the trash。
My battery's been in operation for almost 40 days, with short videos, tweets, electricity, drums. The recharge cycle showed 92 per cent, similar to when it was bought。
It's not broken, it's just that nobody told it "can wake up."。
