Protect & Prolong life of your iPhone's Battery: About the battery usage on your iPhone, iPad, and iPod touch ...

Try some of these options too.

1. Put on Low Power Mode
2. Put Auto Lock On (1 min):- with low power mode it will be 30 Sec
3. Put Auto Answer Off
4. Disable Push notifications for apps you do not use often
5. Enable Auto Brightness:- Settings > General > Accessibility > Display Accommodations > Auto-Brightness [Enable]
6. Manually lower brightness from Control Center
7. If you Want to watch continuous Video. Stream it on TV or a Monitor
8. Don't force close apps; Apps which are not on frontend screen are paused by the system to save energy. Apps require more energy to re-launch. Apps which are open in the background use large memory is a myth and quitting them is counterproductive
9. Location services to be allowed only while using the app
10. Set your iPhone to fetch email and calendar data from internet less frequently
11. Turning off Background App Refresh 
12. Charge before it drops below 20-30%
13. Try connecting to trusted Wifi where ever available in stead of Cellular
14. Enable Airplane mode in areas with bad cellular and wifi coverage. Your phone keeps trying for reconnection with the missing / weak network. This uses lot of energy
15. Switch off Wifi & Bluetooth while in Roaming or Not in Range
16. Enable "Wifi Assist" : Settings > Cellular or Settings > Mobile Data > Wi-Fi Assist [Enable]
17. Periodically Check your Battery Health (Settings > Battery > Battery Health)

Here is the problem with your response. My battery is only a day older since my iPhone 7 updated itself to 13.1.2 overnight. Yesterday my kid played his noggin for 3 hours straight and the battery was at 70% when he put it down. It’s a video heavy, interactive app for kids. 10% drain per hour.

This morning, after the update, I was on a conference call for an hour, voice only, and the battery dropped to 20% from full charge. So tell me how much did my battery age over night to loose efficacy like that?

This update does not make me happy at all.

How we can let Apple know about the iPhone7 battery drain problem? Battery is empty in 10 hours without usage.

You can contact Apple here:

Genius Bar Reservation and Apple Support Options - Apple

They can do diagnostics remotely.

In my discussions with Apple Support and Apple Care, they are not seeing a widespread issue and whenever I speak to a support agent, they are really asking for more people to contact them with their issue. Even if you do not have Apple Care and your device is an older one, please DO contact them by phone.

They really need your report, so there's more visibility.

So here's an update to my issue:

I've updated my 7Plus to 13.1.3 in the hope that it will resolve the battery drain issue - FALSE HOPE! There has been no improvement at all in my battery. So it seems that Apple has really screwed us up this time! I had a perfectly functioning phone until an "improvement" update!

The "update" happened last Monday 14th October overnight so I have taken a screen shot of battery "drain" before and after the "update" - one can without doubt see what the "update" has done. In the time I've had this phone I have NEVER had to charge it around mid-day with hardly any usage at all.

Since this latest 13.1.3 "fix" hasn't fixed my phone at all, I will be taking Apple's indirect advice and get myself a new phone. It's gonna be a One Plus 7T Pro. Apple, I really hope you're ashamed of yourselves! :)

So I’m in the Genius Bar in Birmingham UK and they confirm that iOS 13 has been an issue. All in-depth diagnostics done again and confirmed that no unusual usage and the battery drain is too fast for very little usage on my phone, at least we’re not all imagining it. They recommend a complete wipe and reinstall. The recommendation is to use the phone for a few days without restoring from backup and see how it performs. So my phone has been wiped and I will use the phone in a raw state to see how it performs. A call back from Apple has been arranged for this coming Sunday 10 November so I will give you a further report after that.

The answer to my question, ‘what if this action doesn’t resolve it? We will have to escalate to engineering, but likely the outcome will be to wait until the next iOS update’. 🙁

To confirm, my device is S6 with 13.2 installed and a battery that’s 11 months old with a 98% maximum capacity on battery health.

**WARNING: Please do a backup before you wipe your phone. **

After a full charge by 13.48, it drained to the low 10’s in about 6 hours. And this was after a full reset and not downloading my apps. So the only apps on the phone are Apple apps as part of the software. This reset also did not work for me.

I also received this after some comments I made.

“We removed your post Battery Drain iOS 13.1.2 on iPhone because it contained rants or complaints that weren’t constructive. We understand wanting to share experiences, but these forums are meant for technical questions that can be answered by the community.”

I have the same issue.

My iPhone 7 Plus on iOS 12 used to last me the whole day.

After iOS 13.1.2, my phone's battery level would drop to 35% at 2:00pm with close to no activity.

It would be great if someone can figure this one out.

I have the same problem on my IPhone 8. From 100% to 70% does not seem so bad but from 70% to 30% only takes about 45 minutes when I am texting with someone. I have turned off almost all notifications and still no luck. Hope it is a bug they will fix soon.

I disagree I have iPhone 6s battery just replaced 6-months ago at genius .It still has a battery life of 99% and lasted all day no problem .Now with iOS 13.1.2 the battery drains like a big v-8 engine while you watch the fuel gauge go down it is terrible and unacceptable .As far as I'm concerned this is a planned by Apple to force us to upgrade .I don't know about you but I had enough . I am now disabled and just bought this phone in mint condition and have no money to replace .Very unhappy with greedy big companies .

It has nothing to do with charger . It has everything to do with Apple iOS .They want people with older iPhones to just say its time for new one .Not me my iPhone 6s is mint and battery is 99% on health ,replaced at genius store and my phone was working good and did have excellent battery life ,now it doesn't since New updates 13.1.2

I see the comments and in my opinion do not install 13.1.2. It is messing with a couple apps of mine too besides the battery. What I don't know is if the battery gauge is accurate or not. It is possible the battery is fine and the gauge is messed up or visa versa. Whatever it is hope Apple sends out another update and fixes it.

I was just planning to buy new iphone XS...but now changing my mind...this is not the 1st time i face this...last time i update my ios...my phone software crash...have to reinstall everything...so sad...to get iphone its expensive but in return...u get ****** software

I use iPhone SE and had no problem with batter till upgrade to 13.1.2 . Prior my battery was holding like 24-29 hrs with standard use of phone . Now a 12 hours later my battery dropped from 75 to 16 % within 3 hours ( no video , no games ) . And % are dropping from 18% to 11% within 5 minutes . I red all above and I do come to think that if release of new IOS harms usability of older phone that means something about how company treat client. Which is very low in this case ! If that is policy of coompany my next phone will be most likely not-iPhone .
