iOS 15.3 battery drain

Hello,

These are the standard steps for short battery life. See if anything helps:

1) Have you tried a restart?  If not, do it now.

2) Go to Settings > Battery > BATTERY USAGE BY APP to see the apps that are consuming your battery.

3) Check “Battery Health” in the link: 

iPhone Battery and Performance

4) If all else fails, consider a battery replacement:

Good luck.

Exactly the same issues with all phones in our family - regardless of phone age (various), battery health (70-85% across devices), usage (mix of apps and usage patterns), turning tracking off and on, changing mix of apps in use at any one time, using the latest OS release, starting and restarting phones, this issue persists. It’s obviously something at the operating system level in OS15 - fiddling with phone settings is a waste of time. Been frustrated for weeks since phones randomly go from full battery to nil in minutes, and sometimes they don’t. The inconsistency is nuts, and none of the responses from Apple actually address this issue - could someone from Apple please respond with anything other than a standard form letter? Thanks!

I'm running the same iOS on ip12 apart from the little blip at 8pm where I plugged it in to get 15.3.1

Perfectly normal. and you can see how long each hour I was online. The all night usage is my bedside clock display and the optimised charging is also shown.

Apple are not here to hear uour plea but you can reach out to Apple Support directly. You should be able to reach them here: contact Apple Support

Alancito, you are aware of the fact that 15.2 and 15.3 are not listed in the "iOS Version" drop-down menu. Some countries are not listed either (mine isn’t). Do you really believe that Apple are reading the feedback? It would be nice if they did. I sincerely doubt they do.

"...Apple please test your code before deploying!!! ..."

Much testing is done by users like you and you are welcome to join the public beta testing program, though we can't discuss results here.

Toon Up ~ 83% indicates an unhealthy battery and is expected after six years. Have the battery replaced and all will be well:

Your wrecked battery or failed charging system has nothing to do with the update.

Arrange a repair

 Hopefully it is just the battery.

Have you ever used a non-Apple lightning cable?

bessy ~ 86% isn't too bad, but more importantly the battery is 4.5 years old and thus due for replacement. Also, the long process of applying an iOS update can strain a weak, aging battery and be the proverbial "straw that broke the camel's back".

A battery health of 77% indicates an aged, weak battery. Have it replaced:

No, it's not surprising – because these are primarily user-to-user communities.

The general press, Forbes, AppleInsider, Macrumors, none of them have reported a problem.

That is quite normal. You would expect 15% usage overnight unless you powered it off. Iphones are never idle.

Always charge your iphone ALL NIGHT EVERY NIGHT.

Sorry posted in error I was in the wrong thread.

Actually yes, anyone level 2 or above is expected to report to the moderators where "terms of use" are abused.

Fancy getting there? Solve a few hundred user problems is all it takes to get to level 2.

Meanwhile read this and if none of it works get a new battery.
