iPad Battery Starts to Weaken after a few Months

[DoFoT9]

What is the difference between 'go fully flat' and 'fully cycle (discharge)'. I'm getting mixed massages here.

haha sorry. "go fully flat" is pretty much when the thing gets to 0%. in reality though the device will still have some reserve charge, of a few % (which we do not see). generally, if you leave the device at 0% for a few hours it will eventually completely go flat which is a "full cycle"

now, unfortunately there are things that further complicate this, a full cycle is generally considered a 100% combinatorial use of the battery. so if you charge to 100%, then discharge to 50%, charge to 100% and discharge to 50% again - that is considered 1 cycle (50%+50%=100%). if you charge to 100%, discharge to 25% 4 times over, that is another cycle (25%+25%+25%+25%+=100%). bit confusing - hope it explains itself :\

I somewhere read that Apple recommends a 100% battery discharge once per month for optimum battery performance and accuracy of the battery level.

yea that was my (discharge) every 30 cycles - assuming that you give it a cycle once per day.

I may have found the issue. Will report findings later but I realized I installed the iPhone app for the Apple Store on my iPad recently. I deleted it an hour ago, have not used my iPad since and battery level has not changed even 1%. That app was one that had notifications enabled. I guess the iPad might have issues with iPhone only apps but ironic that Apple Store was giving me problems.

Will try another overnight charge tonight and see if I get any battery loss.

aaahhhhhh glad you found it OP!! good to know

I will try deleting the Apple store app. I've noticed mine going down, too.

Mine was at 66% this evening and I think it was in the 90s before.

I also noticed the mail app was set to fetch for data even with it bring set to manual check. I don't know if that means anything either.

As someone else mentioned, you probably downloaded an app with notifications that is wasting battery life. Words with Friends notifications could wipe out an iPhone battery in a few hours when it was originally released. Disable as many notifications as you can and you will likely see an improvement.

Does this really hurt battery life that much? So if I have the facebook app open and my email set up to push it kills the battery that much?

I have the same issue where I would show 45% battery, play an app (like angry birds) for 20 to 30 minutes and iPad would just turn off. Then I'd plug it in and check back in an hour and it would say charging but it would be up to like 60 to 65% or so. There is no way it would charge that quick.

Also, it would say 100% charged so I'd unplug and use for a little bit (not 2 hours for sure) and it would be down in the 70 to 80% range.

There's no rhyme or reason. No consistency with battery info. Doesn't seem to show correct. I'll try disabling mail and notifications but then why would they give us a product that can do that type of thing and not expect us to use it.

I've had mine for about 2 months, i have noticed a difference Id say maybe 10/15% drop in battery life. It's not something I would consider a defect. I can still get almost 2 days out of it with moderate usage.

My iPad seems to be gradually lasting less and less, I hope there is a way to replace it because I fear what will happen at the end of a year or two!

General battery rules, never let them go fully flat, store at 50% charge for long periods of time, fully cycle (discharge) once every 30 cycles.

How does one fully charge if the advice is never supposed to go flat? Am I being picky? My iPad just started to go all the way down (2%) overnight. It's fully charged then in the morning, dead (2%). I had recently changed one email account to Fetch so I've turned it back to Manual. I'll see if this helps.

If Fetch kills the battery so quickly, why even have it as an option? It will kill the iPad while your out and about in a couple hours defeating the whole purpose of not having to lug the laptop out.

Is their a Fly in the Ointment?

had mine for 3 months, and it is attached to my hip so i need to charge every other day at the least. no issues here - and i am jailbroken and i multitask.

3 months here. Jailbroken, backgrounder, circuitous, iWhiteboard, SSH, lockinfo and more running.

I use mine all day, everyday, at work and at home. I drain the battery everyday and sometimes give it a juice up midday, but only because i am anal about not letting it drop under 20% or so because I never know when I'm going to need to run with it for a few hours.

Usage includes web, jump desktop, docstogo on a regular basis and I background the audio for baseballs games through the MLB app quite a bit, as well as the occasional podcast.


I get 10% per hour drain under load, consistent from day-1. Easily the most impressive battery in any electronics device i have ever owned.

No problem with mine either. Jailbroken iPad 3.2.1.

We've got two ipads and they have started to deplete much quicker than before. I noticed this and logged on to see if anyone has started a thread a out this.

So this will get interesting. We'll have to take them to apple to swap out batteries if that's going to ever be an option.

I have a launch day iPad. Battery is still just as good as the day it arrived. Can leave it unused for a couple of days with Push services enabled and its still at 100%. When I use it, it takes about an hour of heavy use for it to drop from 100% to 99%, and then after that its about 10% for every hour of heavy use.
