Let your phone go dead or constantly charge it to full.

I have an iPhone X. I’ve seen some subreddits that suggest letting the battery basically die and recharge from there. Is there any benefit to doing that or charge as you go is preferred?

So the general rule with the batteries in the newer iPhones is you want to try to keep it around 80% most of the time and let it drain as low as possible at night before you charge it.
I’ve pretty much put some anker cords all over the house, in the car and at work. It’s just a habit now to pay attention to battery %.

Takes about 3 days for my google pixel 3xl to get down to 20% and then I recharge. I think there are a limited number of charge cycles or something like that. Also, I have read its best to only charge your battery up to 80% as the charger as the battery works at lower voltage between 40 and 80% which is less stressful on the battery. I just fully charge mine though.

Thank you for your input. Love this site to get honest, real answers.

I let mine go to 0% once a month to help the battery monitoring software calibrate.

if you want your battery to last, don't let it discharge below 25-30% and don't charge it above 60-70%. The further you go outside those windows, the faster the life of the battery decreases.

With the style of Lithium Ion batteries today, there is no "battery memory" which in the past made it a good practice to run it to 0% before doing a complete charge.
On a side note, I plug my iPhone 11 Pro Max in every night using a USB-C to lightning cable. The last 2 nights I have gone to bed with the battery around 65% and plugged it in. Upon waking up, my phone is completely dead. I can't figure out why, maybe the charging cable or block is bad? It actually drains the battery, because if I left my phone unplugged all night it would still have plenty of battery remaining the next morning.
I have googled it, and it seems to happen to others as well. Anyone here had this problem?

After working for cell phone repair shop for some time and seeing all kinds of aftermarket batteries and configurations, I've to come to this conclusion.
We've seen OEM batteries from Apple, Samsung and LG get mostly from 700-1000 cycles before starting to see really bad battery symptoms. Since I hold on to phones for about 2 years that's roughly 700 cycles so I just do the burn it during the day, charge it up at night. By the time it needs a new battery I'm already giving the phone back.
Aftermarket batteries are absolute trash and you'll be lucky not to be back in a phone shop with the same issues within a few months.
I upgrade every two years and just get a new 1 or 2 year old model. Keeps your month payment down and at about 4 years old the OS is starting to throttle the phone due to upgrades in RAM and processing in current gens which they specifically make the OS for. You can stay relatively up to date as far as technology this way as well and avoid some headaches.

I charge it to full overnight.
I've read that keeping it between 20 % and 80 % is optimal for getting the most cycles out of your battery.

You're (they're) confusing lithium-ion polymer (Lipo) batteries with Nickel Cadmium batteries (NicCad). (Almost) All modern phone batteries are LiPo's. NiCad's have a memory, Lipo's do not. LiPo's do suffer degradation in overcharge (above roughly 4.2 volts) and over discharge (below roughly 2.3 v) situations. However, your phone has circuitry to prevent both of these situations.

Let's all be completely honest though. 99% of us will buy a new phone before our current phones battery shits the bed.
I have an iPhone 8plus and it says its battery health/maximum capacity is 84%. That's taken 2 full years to drop 16%. Even if that doubled over the next 2 years to drop another 30%, that would put me at roughly 50% of maximum capacity.
That means I would've had my iPhone 8plus for 4-5 years and they'd be on the iPhone 16 or so by then. Time to upgrade.
In other words, at least for iPhones... no one should GAF about their battery health unless you just happen to have a lemon.

whole bunch of nonsense in this thread 
Posted on 2/13/20 at 10:59 am to strohmile126
I don't let it completely die, but I don't charge mine until it gets to 10-20%. I have a charger on my nightstand at home, one at the office, and one in the car. It's rare I'm not close to one. I also keep a portable charger with me most of the time.

Don't know the answer, but I have seen my phones last longer since I stopped plugging them in all the time. Then again, it could also be due to the newer technology as I usually hold my phone for just over 3 years.
Now, I only plug in my phone (Pixel 3) at night if the battery is below 25%. I have a desk job and am in my office 75% of the time; so I can charge it up and try to stop it when it's in the 90s. I'll usually need a quick charge on weekends and usually only get a full charge with long drives

I’ve heard both sides of it.
Always let your phone drain all the way down before which charge it again.
Or
Newer phones have batteries that doesn’t really affect.
I have a X and I basically keep it fully charged all day and I haven’t really noticed major battery drain. I did that battery health test and it still has 91 max capacity. I’m going on about 2 years and 3 months.

Well, I'm screwed I guess
Have a S9+ and keep a charger at my office and unplug at home gets to 98%, plug in at work on charger all day I'm not at lunch, then plugged in again. Get home at 98% and plug in while eating, then plug in at 80% when I got to bed.

Google is your friend.
There wasn't one electrical or chemical engineer quoted or sourced in that entire article.
There are plenty of actual, real world studies on lithium ion batteries that have conclusively proven that when you deep discharge (less than 30% or so), it measurably reduces the life of the battery every time. There are also plenty of other studies showing how the charging rate (current flow) impacts the life of the battery. The faster the charge, the higher the currents, the more heating loss there is in the battery during charging. There is a lot of data to show you how this impacts and shortens the life of the battery.
Finally, there are also MANY studies on the impacts of voltages over ~40%. The voltage at the terminal of the battery changes with the charge. The higher the charge of the battery, the more voltage it is holding at its terminals. As you go above 40%, the higher the voltage, the more stress and heat it creates with the leakage within the battery. This has also been proven to shorten the life of Li batteries. Holding a battery on a charger is putting an even greater voltage across the batteries and exacerbating the problem.
Does all this mean if you abuse the battery it won't last a long time? No. All it means is you can make a Lithium battery last for almost ever if you really "want" to.
I have a 3 year old phone and it has been discharged below 25% less than 10 times and charged to 100% about 8-9 times (mostly by accident). The battery health is still at a measured 100%.
