Battery drain even after replacement.

So I`ve changed my old battery to iFixit battery, but battery still drains like 1% per min when using. So I`ve heard about U2 chip, but my phone charges normal and when i`m drained battery empty i can charge it. I`ve minimalized usage as possible, but nothing changes.

Ответ на этот вопрос У меня та же проблема

Это хороший вопрос?

previous battery had 527 cycles and power iBackupbot showed 700MAh from 1420MAh so i that needed replacement. Phone have not been any water damage or so. Always charged with apple charger who came in package.

1) Before touching U2 check below steps

Turn off all connectives such as Wi-Fi, BT, Mobile data and check whether any improvement of battery life
Again restore via iTunes and setup as new device ( check the device before restore the all contents of your iCloud and apps)
if above steps not worked for you,

1) Remove insisting battery

2) cut off Old battery contact wire with doc connector

3) Connect Voltage(V) and power(A) analyzable power supply (make sure + and - correct)

4) Tune voltage to 4.0V

5) Turn on the phone pressing power key and measure taking current (mA) and it should be around 5mA to 1140mA if power taking beyond 1500mA your logic board having some kind of short circuit.

let me know the result. there is few steps to check in logic board

Tried first steps, no results, same thing.

Where do I get analyzable power supply? Can I buy it? I don`t think I have one.

Thank you.

And one more thing, phone standby can sit like 3 days if I`m not using it, when I start using rapid battery drain, also I can listen to music, battery works fine with no drains, as soon i unlock it and start even texting drains start, phone is cool and not hot.

Maybe I should dissamble it and put back together? That would change anything?

26 мая 2015 г. из alexjakob

its a variable power supply

Hello alexjakob,

you no need to worried about your motherboard or other components. as you said battery drain without hot.(According to basic physics theories :-) ) fault coming from your battery. if you have battery analyzer you can check the capacity of battery otherwise replace it
