iPad Battery Wear

[Trekker24689]

HI

I Have an iPad 5th gen (according to Imazing). It seems to take ages to charge (yesterday the battery was at 7% and took about 6 hours to charge from about 9.30am to 3.30pm (was working so these are estimates but an app, battery HD+ i have on it said 6h 30m to charge). I thought this was a really long time to charge. I have never really noticed before as i charge it overnight.

However i was looking around and another app battery & charger Test has the health as Good which is fine but another app someone mentioned when i googled looking for apps to check the health is "Battery Life"Battery Life says the battery wear level is at 35% - Very High. I am not sure how accurate these are and wanted someones opinion as thought it might be going. I play a lot of games and read (Mainly couple golf games & Snooker games) and just browse the internet. The Average Screen on time is 3H7m and Off Time is 1h 14m in the last 10 Days (according to the battery in the settings, Pic attached).

I just bought a new charging cable and plug from amazon and the battery HD+ app says the same times for charging for both the old cables/plug and the new ones.

Any help would be appreciated.

Regular iPads do charge slowly. My regular iPad (6th gen) takes at least 5 hours to charge (from 15-20 % to 100 %). In terms of average screen time to be honest I never managed to have more than 6 hours per charge.

How long have you used your iPad? To me it seems that it did take a bit longer than normal to charge and the screen time you are sharing is rather less than normal for those iPads.

Did you check the charge cycles with iMazing?

Have you taken a look at Coconut Battery?

HI Thanks for the reply.

I have had it a 2 or 3 years. Wow thought they were a little quicker regular iPads. Ok.

No i never checked the charge cycles in Imazing.
I have it at 100% and Imazing says it is Good. the screenshot of the charge cycles is below.

If I understand the screenshot correctly (I am not the most knowledgeable Apple user) the battery health is 91 % (everything above 80 % is considered OK by Apple standards) and you have had just 128 cycles and this is also OK. I think that when it comes to such batteries they are supposed to sustain at least 500 cycles (for phones it is definitely 1000 but not sure if this is also true for iPads).

Do you use your regular charger that came with the box? I think that it was 10W. I bought another one that is 12W. It does improve things a bit but not a lot. However I was told that the regular iPads do not support fast charging and I should not use chargers above 12W(cannot tell you if this is true or not). Otherwise I end up risking swollen battery situation.

I have had a mac for years but this is fairly new at ipads and they do most of what i want (reading/playing Games Occasionally shopping (amazon/Asda/tesco)). Glad you think that just worried i had 2 different diagnoses for the health, though i would probably choose Imazing as i like the app.

I just bought a new charger (as mentioned in my original message) but not an apple one.

This one is the new one (Black) and the other is i think the original 12w (white) so no wonder that it could be slow 😉

On 12W charger, my 2017 iPad Pro 12.9 took 3 hours to go from ~45% to 100%.

I get pretty good battery life on A9/A10/A12 chipset iPads. Easily more than 1 hour per 10% battery. However, my onscreen usage is fairly light on the battery: 0-20% brightness, primarily reading books/comics and browsing forums, some online shopping.

 

[Trekker24689]

Thought about the Ipad Pro 12.9 but could not Justify it when mine works fine as it is.

Thats good to know mine is not too bad for the 12w as it would be slower than the Pro.

Thanks

Just posted as a point of comparison.

On same 12W charger, the 2017 iPad 9.7 should charge faster than the Pro 12.9. Regular iPads have ~32Wh battery while the Pro 12.9 has ~40Wh.

The big Pro needs the extra juice. I get longer onscreen time on the iPad 5th gen, 6th gen or Air 3 than on the Pro 12.9.

 

[Trekker24689]

Oh right of course that it has a bigger battery so would take a little longer to charge. Silly me.

Happened to charge the Pro 10.5 today. Looking at the graph, it took 3 hours to charge from ~20 to ~80% then another 3 hours to go from ~80% to 100%.

With what charger? I am not sure if the iPad Pros have optimized charging by default (similar to iPhones). With my iPhone I have noticed that if it reaches 80 % and thinks that I won't use the phone in the next hours, it stays at 80 % and continues charging afterwards. Is it possible that something similar could happen for iPad Pros?

Anker PowerPort 60W 6-port, max 12W per port.

No optimized charging like iPhones. Just trickle charge past ~80%.

Interesting. Does it happen every time? In general I get the idea of slower charging after certain percentage. This is what my Android phone does. The Sony has fast charging but it takes far less time to charge till 70 % compared to the time it needs from 70 % to 100 %. It is not 50 % difference though. I mean if it takes X amount time to charge till 70 %, it takes 0.5X to charge from 70 to 100.

What you describe is a bit more extreme and I wonder if it is just a random iOS/device behavior or there is some logic behind.

As far as I'm aware, that's been standard behavior for a while on iOS. Even on USB PD fast chargers, it does something similar. 30W up to a certain battery percentage then gradually slower after. It's done to prolong battery longevity.

I think on the iPad Pros (except 9.7), it's something like 50% after 30 minutes with USB PD 30W fast charger. There's a thread here with detailed tests.

If it takes x amount of time to go from 0 to 70% and 0.5x to go from 70% to 100%, that's an almost linear charge rate (0.5x time per 33% battery).

That makes sense. So in a way even for iPads there is some safe gate when it comes to charging and prolonging battery life. It is not like with iPhones where you have the setting and you can decide to activate/deactivate it but there is still something going on.

You are right. My calculations were wrong. It is more like another X time and not 0.5X. Just as the phone is small (just 2600) the whole battery charges for an hour and something. As a result the calculations with percentages could easily deviate when I rely only on my perception.

Before iOS 13, iPhones did the same thing (when using 10-12W charger). Of course, most iPhones only shipped with 5W charger and that one just charges slowly to begin with.

iPhone 11 Charging Test. Which USB PD Charger is better?

iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max have been officially released for a while. As we all know, the Pro model comes with an 18W PD charger and a USB-C to Lightning fast charging cable. For the basic iPhone model 11, although he also supports the USB PD fast charging, but it still comes...

Yeah true that most of the iPhone chargers at that point were slow enough. I wonder if it does not make sense to introduce this setting for optimized charging for the newer iPad Pros as they do support fast charging.
