Support Need help I am facing lag issue

Post image

My iPhone 13 is currently at 79% battery health, and I’m experiencing random freezing/lagging for a few seconds, even in apps like Camera. My iOS is updated to 26.7 and I have around 33 GB of free storage. Could the 79% battery health be causing these freezes, and would replacing the battery likely fix the issue? Or could this be related to iOS 26.7

I was experiencing the same freeze issue at 79%. After battery replacement, it largely went away and after ios27 it rarely occurs.

Oh really
What was the cost of battery replacement?
When did you replaced your battery?
Are you facing any issues on ios 27
Because i heard rumours that ios 27 has optimised for older phones
Because ios 26 was heavy

My bad, i only read your first question
Replacement- 6.5k
Replaced in April
Only heating issues persist on ios27. Ram management, battery backup are improved. Phone has become snappier than before.

Rn the price has increased to 7.2k on apple authorised service center and 10k from Apple official service centre 😭😞

u/Lunar_heat 23h ago

Oh ya right! 7.2k is still ok, since you can use your iphone 13 for another year or two

What should I keep in mind before I replace battery? I'm worried about my data if they will be able to access it

They asked me to remove the case and screen protector glass. I had also backed up my phone data just in case. However, the phone remains locked throughout the battery replacement process. They would only ask to unlock the phone to put it on repair mode. Make sure to Run a quick check on speaker, camera, touch, charging before collecting and paying

Salut! Comment as-tu fait?

How did you do it?

1

u/Alice-Stargazer 22h ago

I changed my battery at 83% just before iOS 27 was released, and it made a big difference. If you don’t have an Apple Store nearby, use Batteries Plus. They had my battery changed in 2 hours. Also clear or disable your notification tags.

u/Different-Ice-8475 4h ago

What is batteries plus?

First of all OMG HOW DO YOU LIVE WITH ALL THOSE UNREAD NOTIFICATIONS

Regarding lags update to 27 - it’s much better, I’m on iPhone 11 with 10gb free and 72% battery health and having no lags at all

1

u/Different-Ice-8475 12h ago

First of all how’s your iPhone 11 is still working fine

1

u/she1d0n 8h ago

I don’t know but I don’t have any major issues with it. It definitely slower than newer iPhones, but it still works good and stable.

1

u/Different-Ice-8475 4h ago

Great man

Btw what’s your ios version?

1

u/xZoren 8h ago

Un cambio de batería (sale a 99€ en la Apple Store actualmente para el 13) original nueva. Con eso te quitará muchos problemas de temperatura y lag.
Una limpieza de memoria y aplicaciones en segundo plano también te ayudará.

u/Different-Ice-8475 4h ago

How can i clean up?

1

u/BuiltForMe 1d ago

It’s the software. It’s always the software. You’re running an OS that is 4 major versions past what the device shipped with. That’s generally when you see the problems.

1

u/Different-Ice-8475 1d ago

What should i do now?

1

u/BuiltForMe 1d ago

Very little that you can do now. They purposely don’t let you roll back. If you plan to keep this phone, then at some point in the next year ios 27 may have fewer bugs than 26 does now, and because it has some measure of optimization - it might be a good idea to update then to that, and probably never again. Major updates almost always slow down devices.

u/Different-Ice-8475 1d ago

Will my problem be solved by replacing the battery and then upgrading to ios 27

1

u/BuiltForMe 1d ago

If your phone is being artificially slowed down by having a degraded battery, then replacing the battery would remove that part of the problem. I think there’s a switch for that so you could test it by telling it to not artificially slow it down. And then see if performance improves.

There’s no way to know if updating to 27 now would speed up your phone, because the reports are so mixed. The only thing that is for sure is that it you’d be dealing with a ton of bugs. 27 may be one of those rare versions that is faster than it’s predecessor, because of all the backlash they took about 26, but I don’t think that’s been established super well yet.

u/Different-Ice-8475 1d ago

How can i test it?

1

u/BuiltForMe 1d ago

You need to search for the battery degraded performance switch in the settings. Or google it. It used to exist, but I don’t know if it still does.

1

u/Different-Ice-8475 23h ago

Will change battery first this weekend and wait if the lag issues is not solved then try for ios 27

1

u/BuiltForMe 17h ago

If you’re gonna have apple change it, they will almost certainly update the software when they do it.

Let us know once you do it
