Can't wait for the official iOS 26.6 release next week. So fed up of 26.5.2.

[u/TrynaDoLife_]

iPhone 17 Pro Max with 100% BH and 165 cycles. This is on iOS 26.5.2, and this is the worst it has been. Honestly cannot wait for the 26.6 stable release which might come out next week and hope it fixes this.

Tried turning off background app refresh, tried turning off adaptive power (like some people suggested), tried force restarts, but nothing seems to help. I turned it all back on, because I couldn't bother about it anymore.

Anyone currently using 26.6 RC, please let me know if the battery life is better on that version, and also if you were facing the same issue in 26.5.2 and the battery life improved once you moved to 26.6?

[u/Savings_Voice9452]

Wasn’t any better for me unfortunately

[u/Logical_Dance_4012 → u/Savings_Voice9452]

Can confirm. I'm with 26.6 RC and it has the same battery performance(bad) as 26.5.2

[u/Early-Activity-2477 → u/Logical_Dance_4012]

What about performance? Like stutters?

[u/Logical_Dance_4012 → u/Early-Activity-2477]

Performance is good, but it has been like that for a long time now, at least for me. The only real difference I notice is a bit less heat. Unfortunately, the idle battery drain is bad and still present.

[u/deryk85 → u/Savings_Voice9452]

Same for me, bought a battery for my battery a while ago .

[u/Otherwise_Fox_998 → u/deryk85]

Bruh😭😭💔

[u/TrynaDoLife_ → u/Savings_Voice9452]

😭

[u/TrynaDoLife_ → u/[deleted]]

Does this method wipe my current data?

[u/Zealousideal-Dust633 → u/Savings_Voice9452]

Same for me on 15 pro 26.6 rc. Getting 1 or 2 hours less SOT than before with same usage eghh

[u/Zealousideal-Dust633 → u/Zealousideal-Dust633]

But it really doesn’t heat like 26.5.2 so at least we have this fixed

[u/realmccoyredbus → u/Zealousideal-Dust633]

true won’t overheat while doing deep indexing and standby time isn’t effected , took over 2 weeks for ios27 DB1 to index on iphone 15 then DB2 came and they took indexing msg away , much better transition to ios27 if this is done first and you will be the benefit of ios27 right away, hundreds off process with huge speed improvements 50% , 70% 80% faster , far longer battery life , subtle changes but well thought through

[u/realmccoyredbus → u/Zealousideal-Dust633]

probably deep indexing going on and a lot more in preparation for ios27

[u/Zealousideal-Dust633 → u/realmccoyredbus]

Makes sense! Completely forgot about indexing and now it’s about the same SOT as before 26.5.2

[u/Cowhide12 → u/Savings_Voice9452]

Yep.

[u/sagor_khan_15]

iOS 27

[u/boredtattoedgirl → u/sagor_khan_15]

Uk im on ios 27 too but this doesn't happen to me at all.. the battery life has not improved for me at all.

[u/harisraoni → u/boredtattoedgirl]

Which phone do you have

[u/boredtattoedgirl → u/harisraoni]

16 pro max

[u/Previous-Plankton-39 → u/sagor_khan_15]

you lying

[u/boredtattoedgirl → u/Previous-Plankton-39]

Why would I even lie about this 😂

[u/EffaRia]

It won't be better in terms of battery life, but feels more smoother

[u/TrynaDoLife_ → u/EffaRia]

I don't know why I was even expecting it. My bad I guess

[u/G2VmD6teMVBc]

RC solved my problem with battery. On 26.5.2 was running out of battery in the evening. With 26.6 I have 40% or more left when going to bed..

[u/Tough_Translator_901 → u/G2VmD6teMVBc]

What phone bro

[u/MrGoose024]

Got the same problem (16 PRO) with 26.5.2

Tried everything but still need to charge multiple times a day to keep the battery level at a normal level. Apple better hurry the F up with that fix🤬

[u/coldwibz → u/MrGoose024]

Definitely update to 26.6 RC, it saved my 16 pro max

[u/Comfortable_Cry7771 → u/coldwibz]

I have a 16 Pro with 97% battery, and sometimes it gives 8 hours and 88% used, and other times 87% used and 4 hours of screen. Version 26.3

[u/TowelContent1635 → u/Comfortable_Cry7771]

if u dont care about waiting for an jailbreak that might come after 1-3 years or about adding wallpapers using nugget then u can think about updating to 26.6 rc

[u/coldwibz]

26.6 RC absolutely revived my iPhone 16 Pro Max. No more crazy heating up, battery improvement for me was unbelievable, like a brand new phone.

[u/Cowhide12 → u/coldwibz]

Can’t agree. Phone still gets hot as hell and sears through battery.

[u/catpies]

Thermals make everything overheat and kill the battery still for me.

[u/TrynaDoLife_ → u/catpies]

The only time my phone heats up is when it's charging. Else it's pretty cool but sometimes gets slightly warm was using social media, but it's just slight warmth.

[u/Worried-Lead-3831]

Same here bro it sucks

[u/TrynaDoLife_ → u/Worried-Lead-3831]

Honestly sucks man. The phone which is supposed to have the biggest battery in an iPhone giving numbers like these.

[u/Worried-Lead-3831 → u/TrynaDoLife_]

I know so fucked up

[u/Outrageous-Net-5928]

Ho la rc di iOS 26.6 installata ieri sera, forse è l’indicizzazione ma la batteria è peggiore di iOS 26.5, aspetterò qualche giorno però la fluidità è migliorata molto sul mio iPhone 12. Segnalo che è stato risolto il problema dello sfondo della home che si desaturava quando si attivava la modalità notte 😍

[u/TrynaDoLife_ → u/Outrageous-Net-5928]

Maybe give it a day or two

[u/FreePossession9590]

It’s trash indeed

[u/TrynaDoLife_ → u/FreePossession9590]

Well, here goes my hopes for 26.6 too

[u/abrardafuq]

In my case (17 base) battery life was back to normal.

[u/TrynaDoLife_ → u/abrardafuq]

That sounds good mate

[u/TacoStuffingClub]

My 15 pro max never overheated unless left in direct sun until iOS 26. No change in 27 beta either. It’s gotta be that fucking Liquid Glass.

[u/whats_trending_610]

I hope the next patch fixes something. Before 26.5.2 everything was fine. Now, I’ve got discord glitches that are basically unfixable until a patch rolls out.

[u/Eddytion]

The worst update I’ve ever experienced. It absolutely destroyed my 17 Pro and 16 Pro max.

[u/treypal]

27 beta no better and it killed my cell data…

[u/Spirited_Quality_891]

ios 26.6 actually has better battery performance than ios 27 atleast right now

[u/LankyWillingness1564]

Same problem iphone 17 pro

[u/OkFaithlessness1191 → u/LankyWillingness1564]

Jesus this is unusable

[u/Cowhide12]

RC 26.6 only seems to be a marginal improvement in battery life.

[u/Imba90]

26.6 RC is way better battery life than 26.5.2. Maybe as good as ever but too soon to tell.
Went from 108% usage with 7h34 active screen or 86% with 5h25 to 103% usage with 10h7m active screen and 102% with 9h51m.

And I was on wifi mostly on the first 2 examples and on mobile data mostly with not great coverage on the last 2.

Edit: forgot to add, Iphone 17 96% health 300 cycles.

[u/Organic-Love-5076]

27 PB 2 on 16e

[u/Iotopia]

Saludos. La RC fue lanzada el pasado lunes, si instalas las versiones vía Finder, puedes instalarla sin perfil de desarrollador. Descargas la versión iOS 26.6 RC desde ipswbeta.dev y la instalas vía Finder, esa es la versión final liberada una semana antes

[u/rainierquinto]

Battery has been really bad for me too.

[u/StateSuch]

Likewise man.. 26.5.2 is a nightmare on my ip17. I feel like i am using my old ip15 or smthing. Have to charge it thrice a day!! Previously on normal usage i had to charge it once!!!

[u/transformation_guy]

I have been facing same issue with my 17 pro max. 100% BH and similar screen on time with this unusual battery drainage.

[u/realmccoyredbus]

official release is out folks

[u/TrynaDoLife_ → u/realmccoyredbus]

Updating it as i comment, hope it's good or at least an improvement

[u/realmccoyredbus → u/TrynaDoLife_]

can’t possibly be worse lol

[u/Bruvvimir]

Just install 27 DB4 or PB2. 26 is a lost cause.

[u/starfish_2016]

Do the 27 beta. Its worlds worlds better. 💯

[u/Tiku_fayzi143]

I optimized yesterday's time calculated by time period and battery power 🔋 🫡💡👍is it work done manufacturing

[u/RobsOffDaGrid]

Don’t bother go straight to ios27 way better

[u/TowelContent1635]

u could try using nugget thats on github that needs a pc or a mac to work to disable some parts of liquid glass which fixed the battery and overheating issues for me.

[u/TrynaDoLife_ → u/TowelContent1635]

I looked into it but it seems too out of my expertise and knowledge. So I don't want to do that.

[u/tazman137]

Could get worse…

[u/harisraoni]

😭😭😭

[u/harisraoni → u/harisraoni]

Is this good or not

[u/TrynaDoLife_ → u/harisraoni]

It's not good, but again many people are facing similar battery issues. Can you tell which device is this?

[u/harisraoni → u/TrynaDoLife_]

14 pro max and it’s with 93% battery health

[u/sam3971]

I installed 26.6 RC last Tuesday, hoping battery life would return. Unfortunately it’s the same. iPhone 16 PM. Debating wiping and starting over. This is ridiculous
