ios 10.2.1 to 10.3 battery drain

I agree that it was strange that it took several replacement phones before the problem was fixed. Apple's tech people (phone support and at the Genius Bar) said that it was *possible* that there were defective components in the replacement phones. Replacement phones contain some parts that have been salvaged from defective phones which have been returned, though obviously Apple does not re-cycle the parts that made the phone defective in the first place. They test the replacement phones before they ship them out to the stores, but even a new phone can ship with bad hardware. It could be that the likelihood of a replacement phone having a defective part may be slightly higher than a phone that's built with all new components, from the ground up, but I have no way of knowing that.

I've never had any problem this persistent with an iPhone. It was especially frustrating because the diagnostics tests that they ran at the Genius Bar did not indicate any hardware problem, so we kept setting up each new phone as a new phone, assuming there was a software issue. But that didn't fix things. The diagnostic tests seem to be better at flagging major, obvious problems, and whatever was causing the issues with my phones was under the radar.

Hi, Phil; I was referring to your case, but I didn't check the number of replacements. If the problems occurred days or weeks later it was almost certainly not the specific version, or a hardware issue. More likely it was one of your apps that you absolutely had to have.

Your 100% correct! It's SOFTWARE. All our phones were working perfectly before the latest IOS updates. The only apple product updated in my house is my phone, which is the only one with the battery drain problem. There are 33 pages of complaints on this forum with most likely thousands more suffering in silence. It would seem our best hope is that the launch of all the new phones will have the same condition so Apple will be forced to issue a fix.

Hi... since the new iOS update more or less every iPhone in our house showing the same problems. We are using 8 iPhones in our household models 5s, 6plus, 7plus etc. "Batteries draining very quick" sometimes if a phone is showing 10% or 12% battery is left and I put it on the charging suddenly it shows 71% of battery and sometimes it changes again back to 16% etc!!! Phones are totally unreliable. Last week my father was standing on the airport his phone was fully charged when he left our house, suddenly the same things happened with his phone, his ticket & boarding pass was in his phone and he was unable to turn it on!!! after about 15 minutes of struggle it turned on again and he was able to join the queue. In my opinion it is not the battery consumption thing, I am sure there must be a fault in the software which gives the wrong information!!! because i had this problem few time with different phone and most of them are still new phones.

Thanks

What were you told when you took the phones to the Apple Store for evaluation and resolution?

NO!! Quick story. My grandson left his iPhone 5 at my house 3 days ago. He had used it all day and continues to get notifications continuously and his charge level after 3 days without being charged is at 70%. By contrast my 6S is at 77% in 4 HOURS, on standby only. His phone was a hand me down so it has the original battery. Mine by contrast has a new battery, approx. 4 months old. The phone was working perfectly at IOS 10.1. As soon as I "upgraded" to IOS 10.2 my problem started. All future "updates" including IOS 11 have not helped. Since my phone was working perfectly before the update, what else could cause the rapid battery drain? It's clearly a software issue!. This morning I googled "rapid battery drain" and several very resent articles have been written on how to correct this problem. First and foremost there must be enough of an issue to have these writers address this issue. Unfortunately, even though I have done all of their suggestions, nothing has worked because they cannot fix a software issue. Their last remedy, after all else fails, is to carry around an external battery pack. A better suggestion would be to buy a competitors phone.

P. S. My phone dropped 4% (73%) while I'm typing this, my grandsons phone, after charging it is still at 100%.

I did not take the phone to an Apple store as the nearest store is closed for renovation. I took it to a local iPhone repair shop for the new battery. They said there was nothing wrong with the battery but I had them change it anyway. To no avail as the problem never was the battery. As many others on this post have stated that the Apple genius bars can find nothing wrong with their phones and others have gotten new phones with the same problem. All our phones were working perfectly before the upgrade to iOS 10.2 and above. It would be wonderful if Apple would allow us to roll back our phones to the eariler IOS 10.1 or 10.0 to see if that fixes our phones but that does not seem likely.

Agreed - I have exactly the same issue on my 6+. It was fine before the upgrade and battery drain is terrible now. My biggest user (40%) is mail. Apple support just plays dumb like it is not a problem. I tested my battery online with support and there is nothing wrong with it. We need help from Apple. If nothing else go back to the IOS that worked fine!

No !! Read his response. HE said HE had fixed it with a new battery.

When battery drain increases after an update (any update, be it 2.1 to 2.2, 10.2.1 to 10.3 or any update in between) the cause is almost always an app that did not handle the update correctly. You need to find the app and deal with it. As a start, visit Settings/Battery and see which app is using the most power. There are other troubleshooting steps, but they depend on the app that is causing the problem. Most basic are:

• If you can identify the app, kill it by launching, pressing HOME, wait a second, then double-pressing the HOME button to display the multitasking screen. Swipe the offending app up.
• Restart the phone by powering it off, then on again
• Forced restart, by holding the SLEEP/WAKE and VOLUME DOWN buttons until an Apple logo appears
• Restore iOS using iTunes on your computer

There's more, but usually one of these will fix it.

Sorry however I do not think this is the issue. I never use the Apple Music App, (and I mean never) and my Battery Drain is horrendous not to mention extremely erratic. Jumps from 80% to 5% in minutes and then you put it back on the charger and it jumps back up to 80%. Why Has Apple chosen not to bother even discussing his issue. It is also discussed on many other forums.

The arrogance in not wanting to assist is a slap in the face to all their clients.

I am about a month away from fixing he issue........buying a Samsung. Already familiarised myself with the ease of swapping from Apple to Samsung Galaxy I.e. Photos, Contacts, Texts (and for those who use the Music App, even Music)

The Battery Drain feature you introduced with 10.1.2 is he worst feature ever.

Thanks for nothing Apple.

Yes i know that Iphone ******* ***** thats why i never ever buy a new one and will never update my IOS, because when you updating it will break your phone like my GPS it wont recognize my location even its on. i rather to switch in flip phone now

This thread is about the poor battery problem after the 10.3 iOS update. You commented that its fixed by replacing your battery. Clearly this is not true, as others who have replaced their battery still have the problem.

You'll have to read the thread to understand. I'm not here to spoon feed you the explanation.

This is not fixing the battery issue though.

Typical response from a high leveller though...defending Apple and offering confusion to divert attention from the actual issue.

Again, no. Whilst I accepted that he fixed his particular battery issue, I then actually said:

"However, if you look through the thread(s), there are many who have replaced the battery (or had it replaced by the Apple engineers) which has not resolved the issue."

It is a problem I have been reading about since 10.1 actually, last year. I know you high rankers have seen battery issues with each update, there seems to be a high incidence.

For me it's not so much that, but the additional comments from many customers taking phones to the Apple genii, getting the bad battery diagnoses, suggested battery replacement but not resolving the issue. Or the Apple genii not finding the source of problem and in desperation, just replacing the whole phone, sometimes resolving it that way.

Some of these reports (not on this thread) have IT techs managing company phones not getting a resolution. Again, not all their phones. So it is strange.

I'm not saying it's a 10.3.3 issue either, as it happened earlier than that. I was just seeing if 10.3.3 resolved the problem that popped up after 10.1 on some phones.

I'm comfortable and technical enough to have a go at troubleshooting, but after reading the various posts from various sources, I'm not happy to try it (until it's time to replace the phone).

No, there doesn't seem to an unusually high incidence of complaints about battery life following the most recent updates.

What these people don't realize is that the iPhone ALWAYS has a particular IOS installed and any battery problem can conveniently be blamed on that IOS. Then they start ranting at Apple which, I suppose, is easier than actually analyzing the problem.
