After 6 hours in airplane mode, my iphone will lose only about 1% and if its fully charged (100%) then it will stay on 100% after 12 hours in airplane mode

No, that's not normal.. Airplane mode, in the setup you described, is basically no different than 'standby mode'.

Get your battery diagnosed by Apple, either at a store or through Apple Support via phone.

Something is definitely wrong. In Airplane mode, ALL iPhone radios are turned off, unless you go back into settings & turn WiFi or Bluetooth back on.

Make an appointment at an Apple store.

You might want to first try to restore your iphone through itunes and try not to restore it from a back up but rather restore it as new. I was having similar battery drain problem on my iphone in airplane mode and restoring as new through itunes solved it. Goodluck

Back up your iphone to icloud. Do not back up everything. Only back up the things most imporant to you. example contacts, pictures, documents and data. Leave the app data of those apps u dont really need for example facebook or twitter as you can simple sign in again so it would be pointless to back it up. All your apps will be re-downlaoded automatically after you have choosen to back up from icloud. Trust me i have done it already. All your iphone settings like Brightness level and your wallpaper will be restored automatically.

After you restore, you must sync or redownload your iTunes content. Thus, the fastest way to restore your content is to simply sync it back to your phone.

but i heard that sometimes restoring from a back up in itunes can restore the cause of the battery drain too so maybe restoring only important things such as camera roll and contacts from icloud or setting as new would be a better option?

Ah...we're not restoring from a backup in iTunes, we're restoring as "new". Fact is, after you restore as new or from a backup, you have to sync or redownload to restore iTunes content, as none is included in any iPhone backup. And, the fact is, the fastest way to restore iTunes content is to sync it back to your phone.

I wouldn't advise anyone use iCloud for this unless they have a really fast connection.

maybe you are right about it as i am no pro in all this but i just had an expereince with it myself. My iphone battery drained at an extremely high rate. I couldn't get through half a day with 3G off also so first i restored it as new and then restored it from my back up and the battery drain was still there then next day i backed up only my photos, documents and data, few app data and contacts which where about 3.5 GB and it took me around 50 minutes to back up and so i restored it as new and then backed up from icloud and my iphone's battery seemed to become perfecly fine. God knows what's the reason behind all this xD
