iOS 15 Battery Drain: 29+ Tips to Make Your Battery Last Longer

I can honestly say that I have never had any serious battery problems after any iOS update for years. Of course it won't be on par for a few days since iOS is doing a lot of background stuff like re-indexing libraries, but it's not like it goes straight to the toilet.

While I was using a Nexus 6 way back when, every time I flashed factory images for a software update, the battery life went from bad to worse. At best, I was getting 3.5-4 hours SoT. For about a week after an update, I'd be lucky to get 2 hours.
 
Better suggestion: Get Apple's Smart Battery Case, and then just use your device normally the way it was intended to be used and don't worry about this nonsense ever again.

And you would be wrong here. There are more than "one" who wants this. In fact, I have a large group of iPhone user group members who are constantly asking how to turn this stuff off, including me.

Well that is ridiculous, because that's not how the device is meant to be used. There is no justification for it. None. You're a minority of none.

I have a 6s and I replaced the battery last August (still at 100%). I have no complaints about the battery life on iOS 13. It’s as good or better than 12, which for me was a good speed bump, with somewhat better battery life than 10 and 11.

I know everyone complains about 13, there was an occasional hiccup/weirdness around 13.1 or 13.2, can’t remember which but it’s very stable for me at the current 13.3.1. Some have issues with mail (exchange server?) but I only have a few IMAP accounts and it works well for me.

That's interesting, I have a 6S with a replaced battery as well (just over a year old battery now) and it was great right up until I installed iOS 13 last fall. It has been garbage since.
 
Given the battery expertise on this thread, what are the best charging practices to ensure an iphone battery stays functional? I have an 11 pro max that gets an impressive number of hours of use before needing a charge. Can easily go two days on a single charge. As I understand, Li batteries last longer if they are kept between 20% and 80% full charge. As such, at the end of the day, if there's still 70% battery charge left, it seems best to not charge back to 100% over night and, instead, go another day. By then, the battery is down to 30% and ready for an overnight charge. So, recommendations, please. Charge every night or charge when the battery drains down to 20-30%? FWIW, I've read Apple's battery recommendations and find little advice with regard to the best charging practices. Thanks, in advance.
 
Thanks for the tips.

I had most of them enabled already though, tips nowadays can't perform miracles with Apple batteries life which are a joke and buggy ios.

This is redirection for the real cause which is from subpar Intel radio draining battery because iOS is not the issue when it's been gimped over time such as background multitasking being reduced to ~30 secs on iOS 13 vs 3 minutes for iOS 7 through 12 and 7 minutes for iOS 6 and prior.

Did I miss the suggestion to charge the phone before the remaining charge gets "too low" since people have said the battery life is shortened if it is allowed to get to the point that the phone has to remind you that the battery needs charging.
 
My job requires spending a lot of time in my Kia Soul. When the car is not running the usb and 12v charging ports are powered off and I leave my iPhone screen in an always on state.
To preserve battery I have a power bank plugged into the car charging port and the USB port on the power bank plugged into my iPhone. That way my iPhone is always at 100% charge even when the car is powered off for hours.
So in this case my iPhone 7 Plus battery health is at 89% even after 3 years of use.
Might be a good solution for many who have similar cars to keep battery life optimize.
 
It's totally fine to allow Bluetooth access to apps that need it for Bluetooth-enabled accessories

It’s important to point out that Bluetooth audio is a system process. Music/podcast/etc. apps don’t need Bluetooth enabled at the app level to play Bluetooth audio to speakers or headphones.

But they may ask for it for other reasons.

An app doesn’t need you to enable location services if its servers know the location of other phones within Bluetooth range of you and you give that app permission to use Bluetooth.

What’s using your battery? You’ll have to do some troubleshooting.
Charge your battery up to 100%.

Quit all your apps and do a restart. Start a couple of known non-draining app, say notes and calculator.

PS Did Apple replace your battery? What is the capacity?

aha.. thanks! that was actually useful. I thought the ON/OFF button in my Control Center is the same one in my settings. Didn't expect they would have different behaviour.

And why would you? It doesn’t make sense and it’s not at all intuitive. If I hadn’t read it here, I wouldn’t have known either. Glad to help 🙂

My iPad 7 shows battery health percentage.

what’s iPad 7? Which year? I have iPad Pro 10.5 (2017) and there is no Battery Health page in battery settings. I thought it’s an iPad thing not having that.
 
All I know is that since ios 13 it is possible to drain the battery from 100% to 0% on our iphone SEs by walking past a specific building while checking mail. I didn’t believe my husband until it happened to me. Now I just don’t use email on the iphone at all.

Unfortunately, I have done all of that already. I took advantage of the $29 battery replacement early December 2018, so the battery is only a little over a year old and the battery still reports 93% capacity. But I have again had it shutdown unexpectedly at around 30% charge, which is just unacceptable for a battery that is that old. I also have had to basically live near a charger ever since iOS 13, and nothing seems to fix it. iOS 12 was fine, so either my battery started having issues at the same time as the update, or the software is broken.

There’s certainly something wrong. I assume you’ve done a complete reset to see how it may be different. If you’ve had unexpected shutdowns (unless due to very cold temperature usage) I’d suspect a battery issue, even though it says 93%.
 
Number 4's result may vary depending on the wifi network. I found that wifi usage on company or public wifi can drain my iPhoneSE very much. When layer2 filtering is setup is sloppy and there are many wifi clients connected, usually there's lots useless network traffic to/from all clients.

My iPhone drained in a matter of 2 hours more than 50% while it was left on a table. On 4G on the other hand, even inside a building, it drained just about 5%.

I always keep my iPhone on Airplane Mode. I also will shut off the WiFi and/or phone service to help save the battery power. Never use Bluetooth.

That's how I use my iPhone 4 (still on iOS 6.x, and looks beautiful). It lasts a long time between charges even when playing music. My iPhone 6s seems abysmal. Charge it before bed and it's lost 30% by morning, supposedly doing nothing... Still on iOS 12.x.

I do not think Apple would replace the battery for your iPhone 4 anymore, but perhaps a third party would replace it.
 
Went from IOS 12.4 which was running fine on my iPhone 7 plus to 13.5.1. This iOS is killing my battery (which has 94% health) and mail, while giving notifications, does not populate my inbox until I load the mail app and wait for it to run "checking for mail" which now takes an age. Mail is set to fetch every 15 minutes but clearly isn't.

I've spoke to Apple who asked me to:

Reset phone
Remove email accounts then add back
Reset all settings
Factory reset phone

I've done all of these things and yet issue remain. Since factory resetting and restoring my iPhone my battery life is even worse despite following every recommendation in this thread. What the hell - is this how you force me to buy a new iPhone Apple? Better yet drive me away from iOS all together because I cannot fix any of my problems with my phone now?! No way I can relay on a device that doesn't give me my email in a timely manner.
