    I went to a repair shop where they replaced my dock pin and its great. I then went to replace my battery because battery goes out at 20%. When they replaced the battery, i noticed my battery was only at 37% or so. I then used it a bit till it reached to around 12 percent. Around the time it was around 20 percent, i had changed it to low battery mode. By the time it was 12 percent and in low battery mode, i charged it and it went to around 48%. I then left it charged for many hours.

    I look at my iphone now and its at 90% only. Can someone explain to me why this is the case? Could it be because i charged it while in low battery mode? Did i have to wait till the battery drains before i recharge it? As of now, its 90% still.

    I was told if theres any issue, i could go back there. But i assume this might be common? But this is a brand new battery...

    Okay besides this, now my battery drains 1 percent every minute it seems. Does anyone know how to fix this issue? This is basically my 2nd iphone 4s battery replacement. I am starting to think this has nothing with the battery. The first battery replacement, i had issues where battery would turn off at 20%, then 40%, then 60 and then finally 80%. Then after i went to repair shop for them to replace the dock pins... i noticed it lasted till 20% before it shut off. Of course i wanted to fix this issue as well and this new battery... will not charge up to more than 90%. Then once at 90% even when doing nothing to the phone and checking it... it drains 1% every minute.

    I mean, i can't be getting 2 faulty battery replacements right? Because im pretty certain there is something wrong with my iphone. Getting frustrated i paid for these battery replacements only to have this same issue. The thing is i think i rather not even replaced this battery since at least it went from 100% all the way to 20% and it didn't drain at all.

    Anyone have any opinions on this?

    Were the batteries genuine Apple replacements or substitutes? And was the replacement done by Apple or a cell phone repair shop (of which there are many)? Some replacement batteries are cheaply made - not saying that's what you got, but it is possible.

    Wow that is crazy, I remember after an update a while ago my phone did that and everyone said it was the battery swapped batteries out into another phone and it worked fine. I say it can be the update even tho no one believes me...

    Both the apple battery replacements were substitutes. It was done at a cell phone repair shop. However... i find it extremely unlikely both batteries would have these issues though.

    The thing is i recalled my battery first went bad when i updated the IOS to 6 or 7 i believe. For a long time i did not ever update my IOS. So i was using IOS 6 i believe. At the moment... im using ios 9 but i have update to upgrade to another higher up version of ios 9. So should i do that?

    The thing is i think there is something wrong with my phone. However i read so many ppl complain about battery drains. This new battery replacement is horrible. Max is 90% and immediately drops down very quickly even when doing nothing on the phone. Even that battery that shut off at 80%... at least it stayed at 100 percent for a very long time before dropping to 90s etc. This battery just drains it the moment its from 90 downwards.

    What should i do now? Just update IOS to the latest 9.XX?

    Should i just factory restore my entire phone?

    Hi, I experienced battery dropped 1% every 5 seconds and the back became hotter and hotter. I went to the Apple Store, they give me a fresh install iOS (the latest version because Apple Store only provide the latest one). Then everything went well. This problem happened on my 5S but I don't think it is applicable to 4S because the hardware of 4S cannot afford the latest iOS.

    I also experienced the iPhone shut down when its battery is 30% but that's probably because of the extremely low temperature. Maybe it is the time to upgrade your 4S to a new model now, such as SE.
