A battery cycle is when the battery has been charged the equivalent of 100% worth of charge. Charging from 20% to 70% twice is one battery cycle. Charging from 78% to 79% 100 times is one battery cycle.
You should plug in your phone whenever possible, especially overnight.
When you first get a phone, or upgrade iOS, there will be about a week or so where it is doing indexing and other background processing that will take more energy as well
till 85%
Alright
Its good to charge my phone at 80% maximum right?
Plug it in every chance you have. There is no reason not to plug the phone in if you are near a charger.
and is it good to charge it if my phone is 40%\
can you explain to me a bit more datailed that battery cycl
cycle*
You should set the 80% limit, yes. And keep it plugged in even when it reaches the limit, as it will then just run the phone off of the incoming power, and not incur battery cycles.
i mean i can plug it out when my phone gets 85% right?
It's good to charge your phone whenever you can. It should be able to charge about 50% worth in a half hour, and once it reaches its charging limit, it doesn't charge the battery any longer.
can you explain to me a bit more about battery cycle tho?
Ok. Ideally, you'd have your phone plugged in, with the 80% limit set, all the time.
In that case, you would never incur battery cycles.
i mean i need to use it sometimes-
Because a battery cycle is when you have charged the battery the equivalent of 100%.
So of course we don't live in an ideal world.
so its actually good for my phone to stay on the charger like always
Yes
also its bad for phone battery to get under 20% right?
so one battery cycle is from 0-100%?
Yes - or from, say 20% to 70% twice.
Think of it like the battery is a bottle that holds 100ml of water.
And a battery cycle counts how much water you have run from the tap when you fill it.
but why did i get 1 battery cycle even if i did not charge my phone, it was at 72% when i turned it on first and now its on 43%
Maybe put on the charger in the store or something?
alr so like i should charge my phone whenever im able to, in fact?
also my phone shound not be less then 20% of battery right?
and not more then 80%
not really, they never charged it, it was in the box...weird ig right?
Yes. But don't unplug it just because it got to 80%. Set the limit in Settings. That way you can leave it plugged in and it won't go higher. (Well, it will about once a week or so for recalibration, but that's normal).
Yeah, i don't remember if my phone was at 0 or 1 when I got it. Probably like how cars have a mile or two new from the factory
i did set limit
so its normal to be 1 batter cycle when you buy iphone first itme? @candid garden
Please don't ping folks. We'll get back to you as we can. I'm working and can't always respond immediately.
It happens, yeah.
how did my phone charge to 100%
if my limit was 80%
when i woke up i saw 100%

@candid garden Hi Jim, it doesn't really metter if you charge your phone from 40-80% or from 20-80%...
It matters to how many battery cycles you incur. 40-80% incurs less of a cycle than 20-80%. Battery cycles determine your battery’s lifetime. Hence, plug in whenever you’re able to. Don’t avoid plugging in because of outdated advice that doesn’t apply to modern iPhones.
Can you help me on another ticket that i opened
My phone was getting hot after using it few hours for messages etc, is that normal?
I was using it with some pauses
Not non stop tho
Yes, especially when it’s new because of background processing that takes a few days to complete
Hmm alr but can you check my
I setted my battery limit to 80% and it got charged to 80% but i could still see "charging sing" near battery percent?
Just means the power connector is plugged in. Don’t need to overthink it. Now that you know the rules, just use your phone and not worry about the charging specifics from day to day.
Yeah im using it and not overthinking, in charging it from 20-80% or from 40-80% sometimes. Thank you!
Going to close this thread now.

Hey
Un well i got one question
Can i charge my phone if my limit is 80%, and if my phone is 77% rn?
It will just use 3% of battery cycle?
Yes and yes
It’s bedtime and my phone is 72%. It’ll get an 8% charge up to 80% and spend the rest of the night running off MagSafe as it indexes my email.
@candid garden
Plug your iPhone if it's at 35% or lower and charge it to 80%
It has a charge limit to improve battery life
Face id with a mask is the same as the normal
Instead of scanning your face it will just scan your eyes
That way it can unlock while something is covering your mouth
Yeah it scans the specific features of an around your eyes to authenticate you. It’s better to keep it off if you don’t need it, as it’ll be more secure and accurate.
I turned it off
I used it, its been 2 days since i turned on iPhone and i have 1 battery cycle.
Your iPhone must be new
The cycles determine how much you used your battery if it's 1 that means your apple device is new
Yes
Bc i still have 1 cycle count even if i charged my phone today from 40-80% and rn from 27-89%
That is kinda weird

A battery charge cycle is defined as a complete discharge of 100% to 0% followed by a 100% recharge. However, this can also be combined with partial discharges that total 100%. For example, discharging a battery from 50% to 0% twice is a complete cycle.
You mean from 0% to 50%?
Nice
How do i have 1 cycle if i charged it from 40-80% and from 27-80% today?
I believe so
To understand how many charge cycles you've completed, it's important to know what constitutes a "charge cycle." A charge cycle is defined as using a total of 100% of the battery's capacity, but not necessarily all at once. For example, if you use 50% of the battery one day and then recharge it, and then use 50% the next day, those two uses combined count as one full charge cycle.
In your case:
-
First charge: You charged from 40% to 80%. This means you added 40% of the battery's capacity (80% - 40% = 40%).
-
Second charge: You charged from 27% to 80%. This means you added 53% of the battery's capacity (80% - 27% = 53%).
Now, add the percentages together:
- 40% (from the first charge) + 53% (from the second charge) = 93%.
Since you've used a total of 93% of the battery's capacity, you haven't quite completed a full charge cycle yet. A full charge cycle would be reached once you've used a cumulative total of 100% of the battery's capacity.
So, in this scenario, you've completed 0.93 charge cycles today. You would need to use an additional 7% of the battery's capacity to reach a full charge cycle.
Deepseek used
Yes, completing 1 charge cycle every two days is generally considered good for the long-term health of your battery, especially if you're following good charging practices. Here's why:
What is a Charge Cycle?
A charge cycle is counted when you use a total of 100% of your battery's capacity, whether it's all at once or spread over multiple charges. For example:
- If you use 50% of your battery one day and recharge it, then use 50% the next day, that counts as 1 full charge cycle over two days.
Why 1 Cycle Every Two Days is Good:
-
Moderate Usage: Using about 50% of your battery per day is a moderate level of usage. It means you're not excessively draining or charging your battery, which can help prolong its lifespan.
-
Avoiding Deep Discharges: If you're charging your battery before it drops too low (e.g., not letting it go below 20-30%), you're avoiding deep discharges, which can stress the battery and reduce its lifespan.
-
Avoiding Overcharging: If you're charging your battery to around 80-90% instead of 100%, you're also reducing stress on the battery, as keeping it at full charge for long periods can degrade it over time.
Tips to Maintain Battery Health:
- Avoid Extreme Temperatures: High heat or cold can damage the battery. Try to keep your device in a moderate temperature range.
- Partial Charging: Charging between 20% and 80% is ideal for lithium-ion batteries, as it reduces stress on the battery compared to fully charging or discharging.
- Avoid Fast Charging Frequently: While convenient, frequent fast charging can generate heat and degrade the battery faster. Use it sparingly if possible.
Conclusion:
Completing 1 charge cycle every two days is a healthy usage pattern for your battery. It indicates moderate usage and good charging habits, which can help extend the overall lifespan of your battery. Keep following these practices, and your battery should remain in good condition for a long time!
(I need to enable notifications rq)
Ty
I setted limit to 80% while charging, but when it gets 80% it still shows me charging sing....
(But its not charging)
Wut
I have 80% limit while charging
But when my phone battery gets to 80%, i can still see "charging" icon.
⚡️
Is it good and okay to charge my phone if my limit is 80% and if i hage 78% rn (im about to take a shower)
Yes. Plug in your phone whenever you’re near a charger
There is no downside to plugging it in
Hey um i wanna hear other opinions.
I can't finish it when i click this button
When i click on it, it say's "you don't have any subscriptions"
Yes
But at 78% you don’t have to
But you can, and especially if you’re going to be away from a charger later, it’s better to top up
You can’t go wrong plugging a phone in - you can’t overcharge it, it doesn’t affect battery life and is, in fact, required for some of the background processing in iOS 18 to happen. On the other hand, not plugging it in uses the battery, requiring additional charging and adding battery cycles, even if fractional. That’s why the best practice is to plug it in whenever you’re near a charger and it’s convenient.
@candid garden is it normal if i charged my phone 2 times today, iPhone 16 pro max, bought 2 days ago. Yesterday and day before it i used my phone without any charging bc i did not need it today i charged my phone from 50-80% and my phone battery was going down faster i was using it more tho, recording tik tok videos all day.
Battery usage can depend on
- App usage
- Background refresh
To disable background refresh go to Settings > General > Background refresh then disable it
2 - Check your app activity
Notifications can use battery
Should it be turned on or off?
Off
Can i enable it for some apps
Not really necessary and it uses the battery a lot
Sure
I enabled it for apps that i use
I don't have backround refresh for every app
Like discord
Are updates bad for battery health?
My friend tested it and she said yes.
Updating is good at it gives your phone new optimizations, so you should update
It's not bad it may use your battery more because it's finishing
Informations about that after updating can be found in battery in settings
No, but it is important to plug your phone in, especially at night so that the updates can complete in the background which can take several days.
Many people mistakenly believe that an update has affected battery life, when really, all that’s happening is that there is extra work for it to do for a few days and nights, and when it finishes, things return to normal.
So my phone should update while night and it should be on charger
Is apple button to turn off and on your ringbell desinged to get clicked multiple times in a day
Yeah but don't charge it too much because it can affect battery life, only charge when it's at 35% or lower
That’s not true
That’s old myths from the days of like iPhone 10s.
And NiCad batteries, which could develop memories and degrade if you didn’t discharge them.
Not true of Lithium Ion batteries used in modern iPhones.
I usually charge it at 25 or 35 or 40% to 80% anyway, bc i don't have time to charge it anytime lol
More information here. Batteries - Why Lithium-ion? - Apple
Every full battery cycle you incur degrades your battery’s health and lifetime.
Minimizing the number of battery cycles is what matters the most.
Setting the 80% charging limit adds 1-2% after a year according to a large study that was done in Europe.
Ooops
Its not bad if i charge my phone from 27 or 30% to 80% right?
Because i can't charge it often
Just incurs more battery cycles than if you don't have it discharge so far.
@candid garden So lets finish this right now so i can close this ticket.
In the fact, i should charge my phone whenever im able to, im usually busy but its still good to charge my phine from 25 or 40% to 80% right?
The whole point is just use your phone as you need to use it, but if you're near a charger, don't hesitate to plug it in.
The phone's battery is designed to give 1000 battery cycles before getting to 80% health, so even if you fully charged it every day, that's still over 3 years.
Then im good to go from 30-80% lmao
