iOS 9.3.3 battery drain

I didn't say calibrate the battery. All I said was make sure there is one full cycle every 30 days.
Apple's battery page has been updated so I cannot find it. But for the last decade, their battery page has specifically stated to use one charge cycle every 30 days. I will continue to look for the source.
Remember, I'm not saying to discharge it fully once every 30 days. Im saying to make sure you use one cycle every 30 days. I don't care if its 100%->90% 10 times or 100%->75% 4 times, just don't leave it plugged in 24/7 for 30 days otherwise it will diminish capacity.
This is more common in laptops as people don't unplug it and the battery goes unused for 30 days and it hurts the health because the battery goes dormant.

Here is the new Apple battery info. The one you referenced has been gone a while.
To the OP, I would perform the settings>reset>reset all settings before doing a restore as new. That will typically resolve weird issues including battery drain without having to start over from scratch. Also you can restore iOS then restore your backup then do the settings reset and see if it gets better as well. That has been a valid fix since way back.
As long as we remember to use the battery once a few days, we should be fine and the charge cycle(partial discharges adding up to a 100%) could be done over a span of more than a month.
Like you said, leaving it plugged in for 30 days straight would do more than just diminish the capacity.
I should give that a try before I put my 5s back in its box. I don't know if my carrier did that or if they just did a reset and restore. I have my old 5s sitting out turned on with no SIM card in it and it is still losing battery. I also don't have any email accounts or any apps on it and today it lost about 20 percent of its battery by just sitting. I really don't know what is wrong with it.
Where have you got that info? That is contrast all knowledge of lithium batteries nowadays. You can safely store lithium batteries for months without it affects much the capacity.
Also noticing battery drain compared to 9.3.2. I had done the update 9.3.3 OTA. I will try and restore like ya'll say.
Hello, care to share a iTunes download link for 9.3.2? screw it ill just downgrade.
I recall similar type of threads showing up in relation to the iOS 9.3.2 update, and I believe 9.3.1, and many other ones.
Look like something crashes and hangs the CPU at 100%, for that the iPhone become hot and the battery empty. But I can't find the problem, maybe is related to iPod/audio framekit but I can't be sure because it's hard to debug on iPhone. Anyway close all apps from background work but is annoying! Maybe is better to revert to .2....
See what app it says is using battery in the battery settings. Something is using it. Perhaps iCloud is hung up. Signing out of it could help.
There is a "x.x.x is draining my battery!!" thread for every version of iOS Apple has released.
It's honestly a mixture of indexing and corruption of the software. Sometimes something just gets stuck in the background without you realizing it. I always do a hard reboot after an update. Kills off all background tasks. If my battery continues to drain even after a hard reboot, I know sow thing went wrong with the installation and restore. I always make a backup right before updating. I will restore from backup and update again.
But restoring from backup mostly brings back the glitch you had in the first place.
Not necessarily true. The glitch could be update related only. So for example, I go from 9.3.2 -> 9.3.3. I make a backup on 9.3.2 before updating. I then proceed to update to 9.3.3 and the battery 'glitches out'. I then restore the iPhone to 9.3.3 as new and then apply the 9.3.2 backup on top of the newly restore 9.3.3 phone. Therefore, the backup is coming from software prior to the battery issue. I've had to do this a couple of times, seems to fix the issue.
Well, I tried that but it didn't work for me. Turned out that the battery was gone anyway.
I do the opposite. I close all apps and reboot BEFORE I update. Then there is nothing open while its performing the update plus there is plenty of free memory available. Never seem to have the issues folks here experience. Esp with OTA updates.
Guys,
The battery does not cost too much if you buy it from reputable 3rd party. Please replace it for your own convenience and peace of mind.
