iOS 12 draining the battery

I have an 2 years old iPhone 7 (normal one, not Plus) and with iOS 11 and 12 (even 12.1) the battery drains in 3-4 hrs and need to recharge 3 times a day (or more). That was until last week that I went to a Premium Reseller (in my country we don't have official Apple Stores) and do a battery change. The phone with the new battery last 8 or more hours, and only charges once in a day! So the solution for me was the battery replacement. Also, I was noticing that my battery gets hot for the 2 years that I bought the phone until the replacement. The new one doesn't do that!

I had similar issue with my iPhone 6 Plus.

Check your battery health if it’s in the low 80 percent and then most likely you need to change your battery.

I just got mine changed in staple for 30 dollars and I haven’t had any problems.

I backed up my pad and did a clean wipe and restore and the battery life went back to normal. I think something tweaked when it upgraded and a complete refresh must have fixed it.

Day two and still at 74% so back to how it was.

First, check the battery health. Settings - > battery .

Check the activity of battery usage and try to deactivate the inactive services.

Try to use low power mode.

I know your’s is an iPad and mine is iPhone but it doesn’t matter . Mine battery was also fine it was like 82 percent and right after my iOS update it started failing.

This is because there latest update has battery check and other updates that causing this to malfunction

When u check the health what was your percent?

Also how old is the iPad ?

As soon as I changed the battery I haven’t had any issues.

The iOS update caused this and weak battery will fail.

I spoke with the staples tech and he said it is a battery issue since apple had this problem before ...

And trust me my phone will drain and then if I plug it in and do a reset ( 2 buttons held down) I willl get the battery meter to go from 10 percent back to 90 percent .

And right after I changed the battery I have not had this problem

Before going further:

iOS 12.0.1 was released yesterday.

Questions for you:

What device are you on?

Have you updated to iOS 12.0.1?

When you say "draining issue" can you be a little more specific? For example: 10% in a minute, 80% if 10 minutes?

I’m glad to hear this.

Keep in mind that whenever there is an update, spotlight is busy re-indexing in the background. (Some people tend to use their devices more after a new update to check features out, which also uses battery.)

It is quite normal to see a small increase in battery drain for a few days or so after an update due to the indexing.

Please see the suggestions above. And in the link DIRECTLY above yours, I've posted links to contact Apple Support as well as a link to leave feedback . Use those.

Remember if your device was recently updated IT IS NORMAL FOR SOME BATTERY DRAIN while your device indexes. This is a normal occurrence. Give it a few days.

I was so upset with apple sin e this was the 1st time have experience any issue with my iPhone and I have been a member since iPhone 1 all I ever had was an iPhone .

I wanted to throw this to a brick wall bec. It will also crash on me. When doing anything one time I was depositing to my bank and it shut off . I had 100 percent but as soo. As it shut off and then turned it back on it goes to 10 percent and I could produce the same thing over and over .

And it’s the iOS update and battery .

But as soon as I changed the battery it was good .

The iOS update is the culprit.

Well let me know if it is something else I want to know if it’s something else so I can inform other who experience problems

Hola

Check your battery health if you are in the low 80 percent then u need to change the battery .

It’s the update that messed u up and not the phone.

One of my iPads is the same as yours: iPad Pro first gen. 9.7.

Before I answer further, what is your total USAGE time, please?

Go to Battery>Last 24 Hrs and on the right, click SHOW ACTIVITY (which will then say SHOW BATTERY USAGE)

When you've done that, please screenshot the apps/hours and post them here. ( I know that might take a few screenshots but I need to see something.)

Also, if you can give me the name of this random app that seems to be the culprit?

Please go to Battery>Last 24 Hrs and on the right, click "SHOW ACTIVITY" (which will then say SHOW BATTERY USAGE in hours/minutes) and post screenshots of it here. Thanks.

Staple replaced the battery for 30 bucks and it’s been good . No issue at all

Cool!.. Better try to replace the battery if it is under warranty. If not raise the complaint to apple support

Everyone make sure you leave feedback here so apple see it as it clearly is an issue
