iPhone 12 battery draining fast

Usage is ok for me. I’m not losing 1% a min, down about 6% after 1hr on screen. It’s not ideal but I think for now this will have to do until apple patches it up in the next update.

6% for 1h of screen is actually good, on the last 48h with an average of 2,5h of screen per 24h, I don't have a heavy use at office, I run out of battery in 50h...

So even if I consider 20% on idle consumption by day which is huge and not normal at all, it remains 30% ... Which means more than 12% per hour of use! When Apple advertises 20h of video streaming ...

What do you mean by « hard reset » ?

Carloo1, to whom some reference, describes the « force restart » Anyone tried the method « reset all settings » ?

I was once successful to restore iOS with « recovery mode », however I got better things to do..

Yep, pretty much that's what I tested. Anyway, my return period is in 3 days. So I'm sending mine back and keeping updated with this forum then I'll repurchase one once reviews says it's fixed. This device costs way too much to have such a silly issue that takes so long to rectify from a massive company like this.

You are wise, and I will probably do the same ... At least to get a new one and get an extra decision time of 14 days.

Just in case iOS 14.4 finally fixes it.

in reply to one of your previous posts, i agree with you that the battery consumption with normal usage is quite disappointing beyond any test of idle drain. Almost Every time i start a call or reply to one (after a standby period) it loses 1%. On the other hand, with respect to your assessments of the past did you note an improvement after doing the hard reset, if you have done this latter?

thanks and ciao

I don't know if my iphone has a serious battery problem. Since purchase I am using it very little, because i’m using old 6S for Safari, Youtube and the other heavy apps. By doing several tests I reached about 90 hours in stand by, leaving it totally unused. I noticed that the average consumption in stand by (wifi ON) is about 0.8-1% every hour, while the night consumption goes from 2-3% in airplane mode to 5-7% with wifi ON 4g ON and low power mode OFF . My fear is that the consumption during use is excessive ... the graphs I posted show a consumption of 20-25% with 30min of screen on, in proportion only 2-2.5 hours of SOT with a full charge! It seems to me a very poor potential result!

I returned my 12 pro because of horrible battery life. I read this forum everyday to see if it's going to be fixed before I ordered a new 12 series. Other forums said the operating s ystem fourte en dot f ou r is supposed to fix it. Also, older devices are being affected as well. I too was disgusted by the amount of cash I put out on this device for such mediocre battery life. Best thing I can advise you to do is sit tight and keep updated with the forums. Apple support will just tell you SwItCh OfF BaCkGrOuND ApPs and FaCtOrY ReStOrE :)

I don’t really see any devices but the 12 series being affected. People that still have their 11 pro Max’s on here say theirs still function normally while their 12’s drain. I can’t return this thing anymore so I only have a small window to sell it and get back an 11 pro max or be stuck w a **** phone. If it’s a modem problem there is no way they are going to do a recall or replace all the affected units.

I have got exactly same issue,30-35%battery drains overnight,closed all the apps turned WiFi off same result,spoke to the costomer service,they say everything works correctly and they advised me to reset to factory settings done that still the same,I regret I upgraded my phone only3 weeks since got the new phone totally disappointed and this will be my last I phone.

i had an iPhone 12 mini (UK-o2) had the drain so returned and purchased an iPhone se 2020 2nd gen, I have been using it for over a week all good and last night draining started same uk-o2. So it’s not just draining on the 12’s.

all background activity off, mail on manual fetch. Bluetooth and cellular off only think on was WiFi.

So upset that it’s started again, i don’t charge it over night so very frustrating when I need to charge it again before I leave for work in the morning. On 14.3 and 100% battery health brand new device.

Hey, I feel your pain as I put out alot of cash on this device ( more than I ever spent on any device). The best thing to do is return the iphone and use your old android then monitor this forum. Once the issue is resolved ( hopefully with Ios 14.four), repurchase the iphone 12 mini. (Removing the sim card from the device solves the issue... but it's an iphone not an ipod xD)

I dont know what country you are in, but apart from Apples return policy, do you have local trading laws that may apply? Here in UK, products have to be " fit for purpose" and if there is a build or design issue can be taken back to shop for a replacement or refund. I cannot do that as our Apple stores are closed due to Covid restrictions

All iphone mobile battery draining fast

fisrt if the battery health are under than 90

second always made your brightness down and put ur mobile in the dark mood

third when you charge ur mobile don’t turn on the low power mode its not good 😌

have you already posted some battery graph comparison screenshots in this thread? If not could you provide some please, so we can see what kind of battery consumption difference we are talking about?

These are the last days of my return window, so I have to make a decision...

I didn't think so, but I noticed that on 5G Auto my phone connects to 3G occasionally. I trust that it will know what to connect to, what's the best signal and what's most power efficient. I think a solid LTE or even 5G connection (if you have it) is more efficient than a poor 3G signal. iPhones or I guess most phones lose the most battery while they are hunting for connection and pumping more power into the antennas.

Connection doesn’t seem to be an issue for me but the battery still drains in idle. I’ve tried everything, like different types of restoring, 3G, force restarts, turned off Siri and background refresh. No luck...

I also tried the point four update. Still the same.

Constant battery drain without a change
