Weird battery indicator

Hi , I've recently noticed that the battery percentage indicator on my iPhone 4 is not accurate/spoilt . The phone switches off when the battery percentage indicates 22% . It's like the 22% is "2%" on a normal iphone , you get what i mean ? When i plug in to charge , the phone switches on again and shows a 22% charging . I tried restoring my phone but it wont work . I also tried resetting by pressing home and lock button but it still won't work . I can't drain it to 0% because the meter won't go down to zero before the phone switches off , so i cant do a full recahrge to recalibrate my phone battery . Has anyone else faced this issue ? Any suggestions as to what I can do to sort it ?

Thankyou , Shivonne .

iPhone 4, iOS 5.1

Restore in iTunes as NEW, without using a backup. If the problem still occurs, there is a hardware malfunction and you need to take the phone to Apple or whoever provides iPhone sevice in your country.

If the restore doesn't work, fully discharge (till it shuts off, ignore the percentage) and then fully recharge (100%) without unplugging to recalibrae the battery meter. You may need to do this a few times.

Mine has done this for a long time. First time happened after about 2 months of owning the phone, took it to the genius bar 3 times and then finally they couldn't figure it out and replaced the phone. 2 months after that, the problem started again with the new phone and I went to genius bar again 3 times and they said they don't know what it is. I have noticed that the longer you let it happens, the more battery is left before it dies. Starts at 22%, then 33%, then 44% all the way up to 66% was my experience. After it shut down I let it be off for about 1-2 hours to let it completely die, then I charged it to 100% and did a hard reset. It still does it, in fact it did it today, but about once per month I do this and it seems to help. Genius bar is no help, along with all the suggestions of it being a hardware issue.

Yes, recalibrate by running the phone down till it shuts off, then charge till full. But a wall charger, not USB. Same thing happened to me. They all said it was a hardware problem so I just resigned myself to bearing it. But after starting to charge with a wall charger more often with a wall charger, the problem suddenly resolved. I can't believe I nearly sold off the phone

2 weeks ago it suddenly resolved itself but the problem is back now . It keeps going off at 14% . I always charge it with a wall charger . Hope it goes back to normal soon .
