iPhone 4s with iOS 7.0.2 Battery Drains FAST!

I have read everyone's comments on here. When I upgraded to iOS 7.0.2, I honestly did not see where the amount of time your battery is being drained. I have had and iPhone 3s, iPhone 4 and 4s, I have upgraded to an iPhone 5c, as well as having an iPad min. I have thin new software on both of my products. Yesterday I took my iPad mini off the charger at 2pm, and due to my lack of sleep, I plugged it in at 3am today and my battery was at 97%. The thing in reality (you don't have to agree with me on this) is how much are using it? I know when I am constantly on my phone or mini that my battery drains quickly, but I expect that it will do this because of the amount of time I was on it. But when I wasn't constantly using them, the battery didn't drain much at all. So while you are right in thinking this a glitch with the new software, and that maybe true, just try if you can to not use your phone or mini or whatever product you have and you will see the difference in how quickly your battery drains

I do apologize for the grammatical errors and spelling mistakes. I proof read after I posted

@Angela.werry - it seems you are one of the lucky ones not having the problem. That doesn't mean the problem doesn't exist. When I first upgraded my iphone 4 to 7.0.2 it was draining the battery from 100% to 0% in just over 4 hours - on standby! The people who are complaining about excessive battery drain are not imagining this problem. There are various tips around the net for improved battery life such as turning off background updating, turning off motion etc - I tried all those and there was no difference. Even to the point of turning off wifi and cellular, which makes the whole smartphone thing kinda pointless, yet my phone would still drain from 100% to 0% in just over 4 hours on standby. It would be sitting on my desk at work, and all I did was woke it up every couple of hours to see what the battery level was. I downgraded back to 7.0.0 (which apparently is not kosher to talk about, even though I did it with a genuine firmware downloaded from Apple's website, and loaded it to my iphone with iTunes) and I got back to about 8-10 hours of standby time. Significantly better, but still much worse than it was under 6.x

By accident I clicked the wrong thing in iTunes, and it upgraded it back to 7.0.2, and again the extreme battery drain was there. I don't use my phone very much, but I noticed that even on the occasional days when it did get heavy use, it was still draining the battery at roughly the same rate it was draining on the very light use days.

Then yesterday, for no apparent reason, the problem disappeared. I changed no settings yet for some reason it suddenly started draining at about 1-2% per hour on standby, instead of about 23% per hour. Today I even turned a few things back on and it is still only draining 2% per hour. I have no idea what is causing the battery drain, and I have absolutely no idea what fixed it on my phone. But I am certain that it is a bug in 7.0.2 that only manifests under some conditions. The people who suggest this problem can be fixed by going into settings and turning off a few non-essential items, or who dismiss the problem as being in the imagination of heavy phone users, seem to have no grasp of the actual significance of this problem. It is not just a case of people who are heavy phone users finding the battery going flat quicker than they think it should. It is people who have had their phones for some time, and who were happy with their phones, who have found that after updating to 7.0.2 their phone's battery life has become so poor that the phone is almost unusable. We didn't buy smartphones, so we could keep our pocket's warm, we bought them to use as communications devices. Until 7.0.2 that was a function my iPhone filled very well. Since 7.0.2 and until yesterday's miraculous fix, my iPhone became practically useless, unless I was always near a charger.

@grazza72

I agree with you, "The phone is almost unusable".

All these trun off wifi and motion and brightness is not helping at all.

People shouldstop mentioning these unhelpful solutions.

Apple shoudl fix this ASAP!

Today I had my iPhone 4S on wall charger, it was 100% I took it off, made 1 phone call for 1-2 minutes. I looked at the battery and it was 89% with no wifi or 3G on!

@grazza72

You are right!

I did not buy an iPhone 4S for $700 to have wifi and 3G off!

It would be same as Nokia 3310!!!

It may be the same in function but I think the Nokia battery life for stand by was several days...

I wish apple would figure this problem out or at least provide a solution for the problem even if it isn't universal. Clearly something is going on that may not be common to those who experience no problem... I don't think we are suffering mass hallucinations about our phones turning into heaters and draining out... And just because others don't have the problem doesn't mean we are imagining it... Maybe we have a goofy network chip so that given the same parameters as everyone else those parameters cause problems in our phones... Or something... Maybe apple can give us an app that monitors who is sucking up the power so at least we can understand the problem... As one poster noted sometimes the phone will go into battery sucking mode and at other times it is OK... I'm using 7.0.0 and haven't had any problem until the other day when it started over heating and draining out... But then I plugged it in and somehow it relaxed and cooled down and the problem went away. Plugging it in with the last 6.x patch would not have had an effect. Without the option of returning (officially) to 7.0.0 I will not try 7.0.2 because my phone is clearly one of those susceptible to this problem...

Just curious... My phone does not have any bumper guard or shell type case but I had a leather holster type holder... Some times it seemed to more frequently go into pocket heater mode in the holster... And the other day I put my phone in a pocket and it started to heat... Has anyone noticed anything like that where enclosing the phone seems to correlate with this problem?

Understand my 4s is almost 2 years old, battery life will naturally degrade, my battery is back to where it was before upgrading and this is the process I went through that finally fixed it.

I can only state the process I went through and what finally worked to restore the battery life back to pre 7.0.2 install. You can nay say it all you want, but this is what worked for me.

So they knew the update would screw up phones and released it anyway with no warning saying if you install this your phone may be seriously impaired? Thanks for screwing us so you an add a few bells and whistles that are meaningless for most users.

Well, in my case it certainly didn't screw things up. Under 6.1.3 I got around 24 hours of average use. Under 7.0.2 I'm getting close to double that. The other thing is that under iOS 6 there was a big difference in battery life depending on whether I was using 2G or 3G to the extent that I usually kept the 'phone switched to 2G. Under iOS 7 battery life using 2G and 3G are quite similar. Must be to do with how 'phones are set up and how they are used..?

we are in a user to user forum here... not apple....

I think you are replying to the wrong post, or even the wrong thread. Do you have anything to contribute??

Just pointing out that it is not a universal problem and therefore probably solvable.

jeem, I was answering to Sycamore, not you. Your point is well made.

BTW, my iPhone 5 did better also after the upgrade to iOS7....

🙂

My iPhone 4S is literally unusable!!! Jeez!

I apologize for just commenting on the point made Apple knew there were issues and they went ahead and released the upgrade anyway and have done little to solve the problem. I am not pointing fingers at anyone here. Trust me in saying I have expressed my point if view to the proper places. I will refrain from doing so here any further.

Has anyone successfully fixed the issue yet? Apple support just tells one to do the same things posted here.
