U2, battery problems, U2, logicboard problems
Hello,
could you pls give me a guide to change the u2 chip.
I have a problem with my battery. I bought an old second Hand Phone.
I have an iPhone 6. But i do not find any instrcution.
I bought an new Akku. But the iPhone has still some problems. After 10 hours of doing nothing, the iPhone is empty.
If I do nothing, It is not really hot. It feels a little bit warm.
It is possible that the Akku I bought has some problems, but is it also possible that there are other problems?
Do you know how I can solve that problems?
1. could it be the not original display (not from ifixit)
The guy before had a cheap Chinese battery and a Chinese display and he was loading the akku with a really cheap recharger. I throw it in the garbage can.
2. could it be the u2 chip ( I don't know anything about it, I heard only sth about this)
3. could it be the Logic Board?
If someone has some possible solution.
It would be perfect.
(I Hope you understand me, I am from Germany. But I think the English community is more strongly.
So I try my luck here ;)
thx a lot.
Is dit een goede vraag?

10 hours of doing nothing, the phone could still be receiving signal it could have a connection to wifi it could have bluetooth turned on, I don't know if anyone really does leave their phone alone for 10 hours and not use it lol
Anyway try a new battery before anything to do with u2 lol
U2 really Tristar is a usb controller ic on the phone it requires average skill with a hot air rework station at least to change it so do not attempt anything with Tristar also is the phone charging ok???

Thx a lot. I am sorry.
Akku = battery (this is the German word)
So Micro-soldering means it is not possible to do this by myself?
I already made an battery test with IbackupBot.
This Is the result of the test:
Cycle Count: 3
Designcapacity: 1810
FullChargeCapacity: 1900
So this means the battery does work, doesn't it?
So the solution is to sell the iPhone?!
Another last question:
Is it possible that the reason is an cheap Display and it absorbs so much energy. I have also a display error (a blue 1cm big point) thx for the fast answers.
