Do you charge your iphone overnight?

The problem with leaving a charger on for a long period of time is the battery keeps its level at 100% which is no good for the battery. Ideally battery should always be between 40-80% to prolong its life. The charge cycle is many times more if maintained at this level than 100%.

All the time Its ok

i remember reading somewhere that once in awhile u must drain the battery to <20% den charge to 100% to re-calibrate the battery.

Well that is not what the Apple diagnostics say for my iPhone 5 (via Apple tech support). And same with my MacBook and iPad.

Just go with ur own flow la... Whether to charge over night or not isn't a issue. The battery in ur phone will last a good few yrs by then you would already be using iPhone 8,9, 10 Liao...

I also charge overnight as I thought that the charger will auto cut off once it is fully charged?

i noticed while charging, phone is warm.
finished charging, normal temperature, even if wall socket is on

for me, at my convenience, drain till total auto off, then charge

Only unplug when using or making calls.

I charge my iPhone whatever I like because I know I'm going to change a new phone every year so why bother

Eversince i got my iphone 5S, i charge once a day....Usually i charge it every night before htting the bed. The next morning i will unplug the phone from the charging cable...

Now i read some articles that charging over night is bad for battery health. So just want to ask do you guys charge over night as well? How true is this that charging overnight will spoil the battery health?

Sometimes i wake up to see my phone charged to 98% only.... sometime charged to 100% but it changed to 98% immediately once i disconnect from the cable. But the battery still can last me at least a day.....

actually i notice it on my iPhone since iPhone 4. if you restart the phone, it goes back to 100%. not sure if it's a bug or something.

Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table at the right, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).

Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.

Fully discharge it once a month. This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries", which means that they can tell you how long you have until your battery dies (e.g. "2 hours, 15 minutes remaining"). This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.P

Keep it cool. Most people overlook this one. Excess heat is not only bad for your processor (and your lap), but your battery as well. Once again, see the table from Battery University at the right—which you can click on for a closer view—a hot battery will degrade in health much quicker than a cool one. As such, we highly recommend using a laptop stand, like one of the many DIY options we've featured here at Lifehacker. When it comes to your phone, check out our previous Ask Lifehacker on keeping your phone temperature down.P

it happens also to my iphone 4 also previously

Battery and Battery Indicators are two different things.

The battery is a hardware while the battery indicator is a software. The battery indicator can only provide an estimate of the current battery level. Calibration does not extend your battery life, what it does is to correctly let the operating system (iPhone) more correctly show you how much battery life you have remaining.

The iPhone and in fact a vast majority of other rechargeable battery operated products like Android mobile phones or even laptops runs on lithium-based technology batteries. They do not have the memory effect that is observed in the older generation of nickel cadmium and nickel–metal hydride batteries.

Users should not constantly deplete their lithium based batteries before charging them because this would shorten the lifespan of the batteries. The number 1 cause of shorten battery life in lithium based batteries isn't usage but heat and heat is produced when you charge or use your device. Hence you should charge as often as and when possible to reduce the charging times.

Of course these are only a few factors to list...
