Hardware fast disrcharge

[lequern]

Hello, my ps vita that was bought in the summer of 2012 quickly discharges. I saw this phenomenon around 2016 after about a year's pause. I bought a new battery but the problem still persists. I even go to henkaku hack there without any change. I am trying to charge it through the adapter from the mobile with 2A but also ... Quick discharge I mean that evening charge it 100% and in the morning can not even turn on.
i use this psp2 battery fixer from SKGleba but not working

Is it a Vita 1000 with 3G? I have heard the 3G module can drain the battery fast.

 

[lequern]

yes, i have 3g but i do not use it and no sim in console

--------------------- MERGED ---------------------------

yes but i do not use 3g and no sim in console. can you post someone fix?

 

[MrCokeacola]

It still uses power even when not in use and with no sim in it. Fix is pretty tough I heard you need to take the 3G out and mod the firmware. Have never done it myself.

The 3g isn't going to cause the Vita to drain from 100% to nil overnight....

you should charge at 1.5 not 2 amp, try using an official Vita charger or alternatively charging through your PC

before use 2 A i use official adapter with same result

that thread confirms that a 3G battery drains slowly when turned off (i completely agree)....

it doesn't mention anywhere about a 3g Vita going from 100 to 0 overnight.....

I have several 3g vita's, yes they do drain slowly when turned off...... but it takes several weeks of them being turned off before they drain completely......

I think I should try to remove the 3g module but I will not do this because I do not know. some other solution?
