iOS 13.5.1 battery drain

So it’s imperative to calibrate the battery of your device once a month.

That was true several years ago. It is no longer the case. Even Apple stopped recommending it.

Always try to use the charger that came with your device.

Made for iPhone Certified chargers are absolutely fine.

Could you please share the link where Apple had discontinued recommending iPhone users to not calibrate the battery (sensor) of their device?

Secondly, yes, I agree with you that only Mfi certified chargers should be used to prolong battery lifespan.

PS it is a once in a long while procedure to fix a particular problem. There should be no need for regular maintenance in my opinion but whatever floats your boat. Apple don't recommend it anywhere I can find.

Some improvement is seen. Battery drain has become 04 percent per hour from 06 percent per hour. I hope it gradually resolves... like you said to wait 14 days... I hope and wish there is no hardware issue....

Why did you say new phone? Could there be a more serious hardware issue?

I am new to community and already feeling overwhelmed with the amount of support I received from you and many other members.

Thanks a million for always being ready with such appropriate and technically supportive responses.

I am unaware regarding how to begin my own thread and even that I can begin a thread. Do I do that now?

THIS DRAIN AND CHARGE ISSUE IS JUST RIDICULOUS NOW - YOU CAN NOT USE A PHONE ANYWHERE UNLESS YOU ARE HOME CAUSE THE DRAIN WILL JUST COME AT ANY GIVEN MOMENT IF YOU ONLY USE THE PHONE FOR LIKE A CHECK ON INSTAGRAM AND WHEN IT START DRAINING IT WILL JUST GO DOWN FROM 100% TO 80% TO 60% AND SO ON AND WHEN YOU START RECHARHING THE BATTERY WILL JUST DRAIN DOWN REGARDLES AND I?M SICK OF TI BY NOW

APPLE DO SOMETHING TO FIX THIS PROBLEM NOW FOR GOD SAKES

I agree! Even with the new 13.6 update my Battery Drain is terrible. I was able to get through an entire day and hit the charger overnight but now by lunch I could be at 60%. This is a VERY NOTICEABLE drain on the battery and during testing of 13.5 and 13.6 nobody noticed???

Very Frustrating

IPHONE 8

Same here. My iPhone 7 was just fine before 13.5.1 and now since then it has not been like before. Even the hope that 13.6 will dramatically change things and my phone will be "just like before" is gone.

Yes I tried the force restart too. Actually by now I have almost tried everything that was suggested in this forum. Nothing is working. Yesterday night I kept my phone “on” - after charging it 100 percent. In the morning the battery remained 67 percent. And even when I switch off by using the slider... similar battery drains.

Nothing is working.

Battery health still shows maximum capacity 100 %.

New issue as of today:

Iphone charched to 100% and when you start using it for just few things like looking at IG or twitter it will just SHUT DOWN with no warning and will start up again then shut down and show black screen with battery and red line that your battery is almost empty.

When you plug it into a charge it will start up again and will give you battery at 1% and info that you have less then 10% battery left and then in few sec the battery will jump back up to 99%.

This started today and can't fox it. I've done a hard restart, allowed the battery to drain down and even did a reset of settings but the phone is still shutting down!!!

I just know here in England iphone 8 is £49, iphone 11 is £69.

Maybe the euro dropped again?

The England price may drop when we get the UK/US trade deal

US prices quoted don't usually include purchase taxes either then there's import tariffs.

This is my batt performance after a full DFU Restore to 13.6 and an iTunes backup restore. Just over 2 hrs screen time for approx 180% battery usage. 90% battery health. Any other suggestions? Thx in advance.

So took my Iphone to apple service yesterday morning as of now they are still looking at it..

The first thing they did was send me an option to leave my old Iphone 8 and they will give me new Iphone 8 for a charge of 424€ - ARE THEY MAD. Like I wanna buy my 1y 1 month phone again. CRAZY

How long does it take for them to check and fix a problem when you have to pay for it - you would think as soon as possible but now let's see how long it actually takes them and what they come up with.

As for that diagnostics test apple support made me to - it was **** the phone number in my country is always busy they probably have nobody on it anyways. So it was all for NOTHING.

If I'll get new Iphone I'll get something more then SE one but not just now 8is OK for now. I swear I had Iphone 6 for few years before buying 8 and that one was amazing and still working while this Iphone 8 just rediculous- the battery shouldn't die after a year in use and not major use.

So annoying seriously

duybnd83 you said "....So can I say that the "fix" Peter mentioned in ios 13.6 is just hide all Apple's service from the battery report :D . It's a brilliant fix , Apple....."

The upgrade to 13.6 was not given as a "fix". It was given as a necessary security requirement, but I mentioned elsewhere that it has "fixed" it for some - only because the act of reinstalling iOS is often a fix in itself.

P.S. I don't remember recommending anything to you by name so why mention me? I am not affiliated with Apple in any way and would not presume to help them "Hide" anything.
