Chosen Solution

I have a 3G, running on 3.1.3 and 05.12.01. It is jailbroken. The battery it had when I bought it (used) would not charge. So I replaced the battery, and the new one wouldn’t charge. So I replaced the battery block/charging port with a new one, as I found under close inspection that the connector had been damaged, aparently during a previous repair. The phone now charges, but very slowly.

  1. It takes around two days to fully charge a 10-20% battery.
  2. If the phone is on, but locked, the battery drains very quickly - Within a few hours of sitting quietly on the shelf.
  3. If the phone is turned completely off, it holds the charge just fine.
  4. The phone does not seem to be getting hot. So any ideas? Thanks.

If you are simply putting the phone to “sleep " mode and not turning off then it will continue to drain over time (not usually over a few hours tho’) Have you checked the “grounding " prong above the battery on the motherboard is connected to the bezel? if not in good contact it can sometimes cause battery drain as it is using more power to maintain signal etc.. I would also try deleting all apps on the phone one by one and see if a rogue app is causing the problem.

I’d be taking a closer look at the charging port. You said that at first it did not charge at all then you replaced the charging port and it charges very slow. I believe that you may have partially fixed the problem, but may have more damage on the port.

I have a 3G and it was working fine on OS 3.1.3, However I had it update to OS 4.0 and thats when I started having battery problems. Eventually my charger stopped charging the phone, I had it checked and found that the charging IC was damaged by the charger. I had it replaced with a new one along with a new battery and now I have been charging the phone for the last 18 hour and still my battery is showing only 97 % If I use it to make calls or check e-mails it drops down to 92% just like that.Can any one help me understand this problem ?

Solution Iphone 4 batter slow charge SOLUTION Just go to settings > reset > ‘reset all settings’ This is the solution to get the Iphone back to normal (quick) charging!! 100% worked for me after anoying 2 weeks of figuring out WHY it charged sooo slow! You won’t lose data/contacts. Only WiFi passwords and some basic settings, but this is not a big deal compare to the slow charge problem! Success!!

I don’t know if it will help because i could be wrong. But if your using a 3g JB Iphone you don’t have the multi task by double clicking the home button. my suggestion is to us your sb-setting and click on processees. this will allow you to see what your iphone is running. if there is several things going at once it might be your issue.
