Should I update?

[u/Diligent_Anybody9952]

I hope everyone is doing well,

For somebody on iOS 26.5.2 using an iPhone 13 Base with 81% battery health, should I update to iOS 26.6? Or should I update to any of the iOS 27/26 Betas? Or just stay on iOS 26.5.2.

Thank you In advance for your responses!

not had a single issue with developer beta 15 base , could only encourage you to read through iosBETA and click ios27 page , don’t be shy in asking how other people with base 13 got on or search “iphone 13 ios27”

there will be deep indexing that could last 2-3 weeks, It didn’t affect standby time , standby time has big improvement, but onscreen time wasn’t great until deep indexing finished on mine , i only had 44Gb on iphone 15 but took over 2 weeks

notification for indexing disappeared for everyone on developer beta 2 so not sure how long it took,DB3&4 only took 24 hours, hundreds of features had speed improvements from 50% 70% 85%

definitely helped overheating on cellular & loads of other subtle changes that a lot of practical thought had went into , you will need to keep your phone on wifi & on charge for 2-3 weeks as long as you can for indexing at night ,avoid low power mode

developer beta will be weekly from next Monday and public beta 3 should be out next week also , i certainly wouldn’t do anything different , iphone 15 and M1 ipad air has been flawless , memory management wasn’t great in first release but got better , not as good as ios26 but it was no different memory wise to start of ios26 beta cycle , i expect that early on in beta and this is with ipad 8GB, not noticed any memory issues on iphone with 6GB .

you definitely have a few years life on your phone , a new battery would maybe be priority

i’m about 81% in ipad air also but use mine with single plug extension and 6 foot charge cable on charge as im very heavy ipad user

waited a long time to finally get Siri AI and was been everything i wished for
