Just updated this morning, so will have to wait further to see if the battery backup is back to iOS 10 era 😁 or at least better than current. No other feature that seems beneficial to ordinary users.

Nope, didn't change any settings. All your notifications are on, even the one when the screen is locked?

11.2.5 reporting in, no batt drain like 11.2.2 (i think)...
ip6s

currently no, maybe no trotherllingg the cpu due to batt capacity still 99%

wew can't wait for 11.3 my iP6 is a nightmare to use now

Now I will try the 11.3

will try with 7 plus first coz that one im using beta

Quite solid battery life on 11.2.5 for iPhone 7 Plus

Woke up at 7 and been at Event whole day, answer calls and reply Whatsapp

Smoother
iOS 11.2.2 was the worst

Ip8+ on 11.3 beta: Battery drain last night ( 8 hours) with both wifi/LTE on but with batch refresh turned off was still a high 7%
Gone are the days of 0-1% drain as in 11.1.1 and before
I still feel battery efficiency had dropped after 11.1.1
In use was quite similar as previous.

I feel the ios still the same..still smooth buts some apps crash and keyboard lag once in a while but so far still good experience

as expected, the battery stabilized after 4th night. leave it at 100% before slept and woke up it is still @ 100%.

Around 8+ hours

I’m on 11.2.5. Did a standby battery test yesterday. 0% drain over 7 hours while sleeping. The phone was on normal mode, connected to WiFi with some background apps. ✌️

Last night drain was 3%. Well as long as it is below 4% I am happy. I had accepted this drain level 2 to 3% since 11.2.2 onwards. Strange some users reported zero drain ?? I had not much standby notification active - only WhatsApp, mail only. I had checked my battery health yesterday and it was very good at 100%

I’m using 8 plus. Nothing impressive ler, as someone said it’s how we expect iOS should behave.

In stall the Apps call Battery Life.

Good to hear that.
If got high battery wear level on your new iPhone, better go for warranty claim.

4 day later after the latest update, got the battery to normalize.

0% drop

Ip8+ on 11.3b : update on battery drain overnight 8 hours : best so far - only 1%. Looks like is improving over past few days

Check here but sadly I don't appreciate at all such new features

I had been using beta firmware since ver9 on my iPad mini 4 and 11.2.2b on ip8+. Different users had different evaluation of the firmware. I cannot comment much as I am only a light user. No serious significant bugs I would say so far. Normally phone will auto update to official version . However I missed that on 11.2.2b7
Probably 11.3 b was released the next day and phone update directly to 11.3b.
