battery drain iphone 6s 13.1.2

Thx. I’ll have to definitely try the DFU mode restore. As you can see from my screenshot still problems on my side of things. Readings are all over the place. Especially the sudden drops and sudden charging increases in %

Hi all you fellow IPhone 6/6s suffers. ( Ipads as well? )

How about this....

I charged my Iphone to 100% at half past five and left it on standby. I looked at it again at half past ten and it was showing a red 1%.

So I tried a reboot, holding the home button and power button.

On power up it was now showing 76% but quickly dropped to a reading of 46%.

I did the reboot again and it was back up in the 70’s.

I have suspected for awhile now that my phone’s problem ( since IOS 13 ) was not a damaged battery but software that is mis-reading the true charge.

This confirms that definitely on this occasion it was a mis-read of the actual state of battery charge.

Well that was interesting and totally baffling.

My phone seems to vary at random in how the battery performs. Sometimes it appears to charge to 100% pretty quickly and drop rapidly. Sometimes I can power it off using the home button and power button and a low percentage showing at power off will jump right back up to a much higher percentage.

My battery shows 100% healthy.

When it drains quickly it doesn’t warm up so the energy isn’t being dissipated into the surrounding air so it is still either within the battery itself, or as I suspect was never there at all, showing full charge when the true charge is maybe only 20% or so. My battery can’t possibly be charging up to 100%, within the short time it takes, to really reach full charge.

I don’t think though that there is any real consistency in how the battery charges, but it is difficult to get any handle on what’s going on.

While I’ve been typing this it’s been charging from my battery case and has gone up to 88% from 69% but it’s now not rising so quickly.

Same thing happened to me. Launched maps and suddenly phone was off. Powered it on and saw that the battery was flat. I just charged it to 100% an hour ago. I’m seeing this after 13.1.2. Apple please provide a fix.

I have the iPhone 8 and the same has happened to mine. As soon as I downloaded IOS 13.1.2 software the battery is now draining and fast. I was running on 12.1 I think prior and it was working perfectly, I only had to charge my phone once per day. Im currently charging three times a day!

Ive spoken to Apple and it doesn't sound like once you download the IOS 13.1.2 you can go back.

Apple please sort this out, your products are becoming less attractive when battery life is so important!!

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 here. iPhone 6s. I replaced the battery at the apple store about a year ago. in iOS 12.4.1, my battery health showed a maximum capacity of 96% right before my upgrade to iOS 13. Since the upgrade, my max capacity has dropped to 92% and my battery drains in minutes!

It shows me that Mail is using 49%-71% of battery, but I have disabled all mail functions (now fetch manual) and still battery is draining. I was 100% less than an hour ago and am now down to 81% with low power mode enabled(!) What on earth is going on here? I leave low power mode enabled 100% of the time and it doesn't seem to make a difference.

If I don't leave my phone plugged in overnight, my battery is down to 19%-30% in the morning even though it was fully charged before going to bed?

Apple, please issue a fix for this! I would downgrade to 12.4.1 but you took that option away from us. I have a feeling that my battery health will be at 45% max capacity in a few short weeks.

Same problem with my 6S. Battery was replaced by Apple recently. 88% battery health. It seems like my phone drains faster than it charges. I can be at 30% before leaving home for work after a full charge. This was always in the 90% range for the same workflow prior to the update.

I have to put my phone on the cord any time there is one available just to make it through the day. Frustrating!!!

I had the same issue.

Followed the instructions about deactivating location services and background refresh, but no change.

Then...... the phone was not plugged in, the battery was draining super quick and at the point that it said 8% remaining I turned it off and back on again.

Battery level went straight up to 32% and stayed there!

miracles do happen!!

Mine too! I reached out to Apple Support and was told that my battery was consumed and needed battery replacement. My battery health was working fine before updating to 13.1.2. Hope they have a fix ASAP!

I joined the forum today specifically because my IPhone 6S battery is draining like water down a plug hole since installing IOS 13.1.2. I can literally see the percentage dropping right before my eyes within a few seconds. However my mini IPad is still good on it’s new IPad OS. My IPhone battery health reports health at 100%. I have rebooted the phone twice and it showed a slight percentage jump upwards after powering up. The phone also appears to be running warmer.

Hello,

My Iphone 7 is doing the same.

My battery health shows 98%. Everything started after the system update.

This is what I have done so far:

Wiped the phone to factory settings and installed everything again one at the time. Disabled background refreshing, bluetooth, locations and most notifications. Disabled "share iphone analytics". Set email to manually, Running on low power mode.

I also waited 4 days for the new system to settle.

None of the above helped, on top of the battery draining fast in standby it also drains even faster when I make calls and it also gets pretty warm. I don't have many apps installed, I mostly use the phone for calls, text and emails.

With some many things disabled, I might as well go back to my flip phone.

I was wondering if I can go back to 12.4.1. I still have the 12.4.1 installer saved on my mac and maybe install it back using itunes.

Can I roll back that way?

I’ve been losing my mind! About this battery life, I would literally leave work with 90% charge, and as soon as I get there it’s at 20%. I thought it was just because I am using Spotify but I never had this problem before the update. My battery health is at 81%. It’s so frustrating, I can’t open an app without it draining my battery life.

same issue with My iphone 7, never had battery issues and charged only once a day, now, as soon as I updated to 13.1.2 from the immediately prior version, I have to charge three times a day without having modified my useage habits.

seeing all replies in this thread, it is clearly an issue generated by the upgrade, independently from any hardware used:

Is apple working on this issue? would be nice to get a response from SUPPORT.

The new update actually cut my battery time to less than half of what it was before hand on my iPhone 8.

I'd go back to the previous version if I could. If you can avoid the update by all means do so!
