battery drain iphone 6s 13.1.2

I had a similar problem with my iPhone SE. It started some days ago, just after the update. After thorough inspection, I found that one app (an "SOS"-app) was set to continuously check my position (using GPS). I changed the setting to "check only when app is in use" , and now the problem is solved. So check if any app is continuously using the gps-receiver, because that will drain the battery quickly. You can see that there si "unwanted" activity by checking the activity-chart. Normal activity is shown in dark blue bars, but if there is any "hidden" activity, it shows up as a light blue bar. In my case the whole chart was filled. Now there are only the normal, dark blue bars left.

my battery life is also much improved.

the update to 13.1.3 helped but the biggest improvement came from deleting and reinstating my email accounts.

my feeling, and it is only that, is that the new email app has some subtly different requirements on imap servers and imap connections established with ios12 can cause ios to loop consuming the battery.

now i have reinstated my imap accounts all is good for me.

I’ve been experiencing the same issue over the last few months especially after the last update, so I decided to try every possible solution.

After many failed attempts I finally solved the problem, the steps that worked for me are:

1. Do a backup from my phone (iPhone 6s)
2. Put the iPhone into recovery mode
3. Connect the iPhone to iTunes
4. Restore as new phone (Not from backup)
5. Once the iOS installation is done restore the data.

Hope that this solution works for you as did for me, I did it two weeks ago and no problems after that, my battery last as new.

Factory reset did not improve. I have now disabled background refresh for most of my app's, and this seems to have reduced battery drainage a little.

Prior to iOS 13.1.2 i had nothing disabled in Background refresh.

An update on my 6s battery journey: I hope this information will help some of you.

I decided to try and only charge my battery overnight and not do sporadic charging here and there like I used to. Here’s how it’s been working for me:

• • Let phone charge overnight. Unplug it in the morning, and just use it till it dies. I completely ignored whatever the phone was telling me for charge percentage.
  • 9:00 am full charge. Commute to work for 1.5 hours. Used it the entire time for podcasts and music (both previously downloaded to phone. No streaming) Make Bluetooth phone calls as usual. Arrive at work, phone is at 74%. Ignore it.
  • After lunch. Phone gets down to 34%. Ignore it.
  • End of work day: Start commute home for 1.5 hours. Phone is at 18% and recommends low power mode. I enable low power mode. Use phone consistently for downloaded podcasts, downloaded music, Bluetooth phone calls, phone gets down to 7%. Ignore it.
  • Use it a little more in evening. Phone gets down to 3%. Plug in to charge overnight.

I did this every day this past week and noted that although the battery percentage changed slightly from those numbers, I was able to use my phone each day for almost the whole day. Note: On some days, I lowered the screen brightness to help it last throughout the day.

One day, I even started my commute home with 3% and was able to listen to podcasts, music, and phone calls for 1.5 hours and the phone was fine. It was at 1% when I got home, and I still used it lightly for another hour before plugging it in again overnight.

I did a clean install of iOS 13.2, restored to factory defaults and then restored my files from backup. This didn’t seem to make any difference.

Last night, after my phone was in airplane mode all day, I turned off airplane mode, phone was at 34%. I checked my email, and the phone dropped to 24% and then 16% in minutes. I enabled low power mode when the phone prompted me. It stayed at 16% for the rest of the evening until I plugged it in to charge overnight.

It seems that like most folks here, the hardware (battery) seems to be fine. The iOS battery management software doesn’t play nice anymore. Maybe Apple will fix it in a future release. I doubt it. But if I ignore the scariness of low battery percentage, it looks like my 6s can still make it most of a standard day without requiring multiple charges.

I’m never too far from a charger on most days. I can charge in my car, at my desk, etc. I’m not really nervous about being stuck with a dead phone. I’d be more nervous if I was traveling or out and about for a whole day. The unfortunate solution might be to just buy a new phone sooner than I was planning to. That’s a real shame because iOS 12.4.1 was fine and I really like my 6s.

The other much cheaper solution for those who are really worried about their phone lasting a whole day, is to buy a portable

battery pack charger for around $30. There are some really good ones at that price point. Much cheaper than a new phone, pretty slim and light, easy to carry with you, and will banish your fears of being stuck with a dead phone.

Sorry this was so long. I hope it helps some of you.

Update on my 6s: Went to the Apple store here in Austin last Friday (Nov. 1) to have them check my battery that was only installed a month earlier. They did the normal diagnostics and said the battery was okay. However, they were concerned that it was only showing 85% battery health. i also discussed these forum posts with them. The genius bar person was not familiear with the posts. They replaced my battery under warranty at no cost to me.

To make a long story short: my phone is now like new again. battery lasts pretty much all day - browsing web, email, maps, doing about anything, etc. So even though their diagnostics showed the battery was okay, there was something totally wrong with it. Just like anything else, there apparently are a percentage of defective or subpar units in any new inventory.

I have disabled a lot of my apps from being refreshed in the background. It reduced battery drainage a little.

This morning, I installed a lot of app updates. This has also helped on battery performance. Allmost back to normal.

Maybe one of my app's have been working poorly with iOS 13.1.2. and maybe the app developer has fixed it now with a new release.

It is not possible for me to point to a specific app though.

Same problem here with a 6s. Had 94% battery health prior to upgrade, now it's a 89%. Have spent hours, HOURS on the phone with Apple Support and a solid 90 minutes in the store. Absolutely a waste of time. They have nothing to offer and they refuse to admit it is a problem. Support has now done remote diagnostics on my phone three separate times and keep swearing they're working with their development teams to find a resolution. A complete lie, all of it.

I have an Apple branded battery-phone case that is now flaky. If you put the phone in the case while the phone is powered on it does not recognize the battery case. If you bounce the phone (power cycle) it'll recognize the case and start charging. However as soon as you remove it and replace it, even for a second, it won't charge again. Even worse is that my battery was at 20% when I put it in the fully charged case. The case went down to 40% and the phone only managed to go up to 48%. So it took 60% of the case's capacity to charge the phone 28%? I know the battery case's capacity is about 80% of the phone, but this is utter garbage.

Every time I'm on the phone with Apple Support I call out the battery percentage as it drops. I also take screen captures at the beginning, during, and at the end of the call. During a 40 minute phone call the battery went from 28% to 12%. Around the time I announced 18% the support person was laughing.

None of it matters though. They have no solutions. Don't bother taking it to the store, they won't be helpful and they'll just tell you to call Apple Support. The first thing they'll ask is if you did an upgrade and include your old data. They'll want you to wipe the phone and start from scratch, meaning having to download all of your apps again, set them all up, sign in to them, etc. Don't. Just flat out refuse to. It's a waste of your time and energy. I did this on my backup 6s. Complete wipe, went into DFU and loaded the IPSW manually, then downloaded all of my apps. Did not sign into a single app or touch any of Apple's default settings. That phone sitting on a desk dropped 7% in an hour, doing nothing. By the next morning it was down to 65%, with cellular, wi-fi, and bluetooth all turned off (not disabled, but actually off).

This is Apple forcing planned obsolescence. I like my 6s, it's the size I like and I like the fingerprint reader with 3D touch. No way I'm going to spend hundreds of dollars to keep those features with an 8. Cause you know it'll be in the same situation as the SE's and 6's are. Even though the chips are "64-bit" I don't think the OS is optimized to run on them correctly. Why else would your battery drop 5% just opening something like Safari?

Just to demonstrate how flaky, unstable, and unreliable iOS 13.1.2 is on a 6s I fully charged my phone and put it in Airplane mode. It sat for a week and the battery went down to 50%. I enabled wi-fi and bluetooth (still in Airplane mode), it "thought" for about five seconds then shut off. When I went to start it back up I got the "plug in charger" graphic. I plugged it in, and when it auto-turned on the battery was at 10% not two minutes later. In five minutes it was up to 25%. I power cycled the phone again and it jumped to 50%. Got screen caps of all of it. Not that giving Apple hard evidence they can't refute will do the slightest bit of good.

Seriously, we are all the [proud] owners of expensive paperweights. Go ahead an thank Apple for it. And good luck reaching anyone at Apple that'll care to help. Notice how there is only one number to call for any kind of issue? Not even a number or a way to reach Customer Relations. They just shuffle you to a Support person who won't offer any kind of consolation or compensation.

If you do happen to work up to a Senior Tech Analyst make sure to document everything. I got one that told me they'd call me back in 48 hours. When I didn't hear anything I started to email them with the reference # they gave me. The person called me back three days later stating he wasn't at work those two days and he told me he worked four 10 hour days. Another load of crap. If you told me that you wouldn't be at work, then why did you also tell me you'd call me back on the day you'd be off? They lie through their teeth. Don't let them off the hook when they say "they'll let you know when they hear something". Get a number, get an exact date. Have them proclaim something definitive, as it's being recorded, and they'll be on record with it. Even getting them to do that is a challenge.

I really do wish the best of luck to all of you. But having now dealt with this for the third time (iOS 11, 12, and now 13) I can tell you from experience there is nothing Apple can or will do to fix your battery problem. Nothing.

Well it worked for my partner’s iphone6 -

Are you sure you have updated the apps - it may need you having loaded the Apple AppStore app to tap around within it for a few seconds b4 exiting - you may then see some red dots come up on the AppStore app and then they will get updated. After 3 nights going from 100% to zero by the next morning her phone remained at 100% all night not on charge.

In the meantime, go to settings, battery, and turn on Low Power Mode. I was hemorrhaging battery life and tried this as recommended and my battery is lasting now. It could tide you over until we figure out what is going on.

I installed iOS13.x and my phone heated up. I then started experiencing random shutdowns and weird behaviour. so I decided to install iOS 12.4 and it seemed that my phone was OK for a few days.

Then I started getting random shut downs again (iOS 12.4) and my battery manager was telling my that the battery needed servicing (or some equivalent message). So at this point it seems to me that the installation of iOS13.x had put a lot of strain on a relatively old battery and had likely pushed it over the edge as far as it's life was concerned. Batteries are only rated for 500 cycles as far as I know on my phone and I'm sure I was close to that. i've had the phone for three years so it seems reasonable that the battery may be old.

I have now replaced my battery and I haven't seen any undesirable issues (yet!! - I hope I won't either). So this seems to be the solution.

If your phone is showing similar behaviour then it might be the fact that the update put a strain on your battery too. Updating can be very CPU intensive since there is a lot of file decompression and building going on.

Hope this helps.

Same issue with my iPhone 6S. Not eligible for "free" battery replacement per serial number.

If you've never had the battery replaced, it probably needs to be replaced by now. What does it say in Settings>Battery>Battery Health? Unless you're ready to purchase a new phone, replacing the battery will be well worth it. I had mine replaced in my iPhone 7+ just before updating to iOS 13. It's as if I have a brand new phone.

I have ‘reset all settings’ having gone through other ideas offered by ikream.com. So far so good. Battery appears to be holding up.....

13.2 downloaded folks :-).

Who knows. This might be the fix.
