It’s harder to replace your phone’s lithium ion battery than it is to treat it right in the first place. Many smartphones don’t provide easy user access to their batteries. That includes all IPhone batteries from the first ever released model of iPhone down to the latest iPhone model.
Official battery replacements can be expensive or inconvenient (try getting an official battery replacement at an Apple Store). There are also environmental concerns. Smartphones are, frankly, an environmental disaster and extending the lifespan of your phone battery helps mitigate that.
Battery lifespan vs. Battery life
By battery lifespan we mean how many years and months your battery will last before it needs to be replaced. In contrast, battery life refers to how many hours or days your phone will last on a single charge.
Now, with the confusion about the battery lifespan or battery life of your iPhone taken out of the way, we can now proceed to enumerate some of the things you can do to preserve and extend the lifespan of the battery of your iPhone.
1). Understand how your apple iPhone battery degrades.
With every charge cycle your phone battery degrades slightly. A charge cycle is a full discharge and charge of the battery, from 0% to 100%. Partial charges count as a fraction of a cycle. Charging your phone from 50% to 100%, for example, would be half a charge cycle.
Do that twice and it’s a full charge cycle. Some phone owners use more than a full charge cycle a day, others use less. It depends on how much you use your phone and what you do with it. Battery manufacturers say that after about 400 cycles a phone battery’s capacity will degrade by 20%.
It will only be able to store 80% of the energy it did originally and will continue to degrade with additional charge cycles. The reality, however, is that phone batteries probably degrade faster than that. One online site claims some phones reach that 20% degradation point after only 100 charge cycles.
2). Avoid placing your iPhone in places with extremes of heat and cold.
If your phone gets very hot or cold it can strain the battery and shorten its lifespan. Leaving it in your car would probably be the worst culprit, if it’s hot and sunny outside or below freezing in winter.
3). Avoid fast charging your iPhone.
Charging your phone quickly stresses the battery. Unless you really need it, avoid using fast charging. In fact, the slower you charge your battery the better, so if you don’t mind slow charging overnight, and go for it.
Charging your phone from your computer as well as certain smart plugs can limit the voltage going into your phone, slowing its charge rate. Some external battery packs might slow the speed of charging, but I’m not sure about that.
4). Avoid draining your iPhone battery all the way to 0% or charging it all the way to 100%.
Older types of rechargeable batteries had ‘battery memory’. If you didn’t charge them to full and discharge them to zero battery they ‘remembered’ and reduced their useful range. It was better for their lifespan if you always drained and charged the battery completely.
Newer phone batteries work in a different way. It stresses the battery to drain it completely or charge it completely. Phone batteries are happiest if you keep them above 20% capacity and below 90%.
To be extremely precise, they’re happiest around 50% capacity. Short charges are probably fine, by the way, so if you’re the sort of person that finds yourself frequently topping up your phone for quick charges, that’s fine for your battery.
Paying a lot of attention this one may be too much micromanagement. But when I owned my first smartphone I thought battery memory applied so I generally drained it low and charged it to 100%. Now that I know more about how the battery works, I usually plug it in before it gets below 20% and unplug it before completely charged if I think of it.
5). Charge your iPhone to 50% for long-term storage
The healthiest charge for a lithium ion battery seems to be about 50%. If you are going to store your phone for an extended period, charge it to 50% before turning it off and storing it. This is easier on the battery than charging it to 100% or letting it drain to 0% before storage.
The battery, by the way, continues to degrade and discharge if the phone is turned off and not being used at all. This generation of batteries was designed to be used. If you think of it, turn the phone on every several months and top the battery up to 50%.
6). Don’t you just leave it charging overnight
Ever since smart phones arrived, the most common way of recharging them has been to plug them in when you go to bed, then disconnect them in the morning with a full charge to last the day.
This made a lot of sense when batteries took a long time to get up to full charge, as the eight hours in bed gave both the user and device time to recover from the previous day’s exertions.
But now, as the period it takes to charge a battery has dramatically reduced, it’s time to reconsider how you top up the tank.
7). Know the recommended phone charge capacity from iPhone.
iPhones use Lithium-ion batteries because, Apple states, they “charge faster, last longer, and have a higher power density for more battery life in a lighter package”. These are all fine features, but one thing that Li-On is not really keen on is being reduced to 0 percent and then back up to 100 percent each day.
Apple recommends, as do many others, that you try to keep an iPhone battery between 40 and 80 percent charged.
Topping up to 100 percent isn’t optimal, although it won’t necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery’s demise.
There is an exception, as it’s considered good form to do a complete 0-100 percent charge about once a month, just to keep the battery in good shape.
For all other instances, though, the best practice is to top your battery up periodically during the day so that it stays in that sweet spot. Hopefully, this should keep the cell healthy for as long as possible.
To make this easier to achieve we recommend keeping an extra charger at work or in your car so that you can pop the iPhone on to it when you see the battery beginning to fade.
8). Do not just charge your iPhone with any charger.
If possible, you should use the charger that came with your device. If you have an iPad, then the charger that came with it is also compatible and may actually get your iPhone up to a full tank quicker than its own charger.
9). Take off your thick iPhone case when you are fast charging your iPhone.
No. So long as your iPhone has the Fast Charge capabilities (this includes the iPhone 8 and later) then the battery and iOS work together to ensure that it won’t overheat or cause any harm.
If you have a thick protective case on your iPhone, it might be a good idea to remove it while using a fast-charger, just so the heat dissipates easily and doesn’t trigger the software warnings to slow down the power flow.
10). Avoid leaving your iPhone battery uncharged for long periods of time
Don’t leave your iPhone battery lying around too long at 0 percent when it is not being used for a while, you should try leaving it with around 50% charge. You’ll find the battery will drain between 5- and 10% each month, and if you let it discharge completely it might become incapable of holding a charge at all.
11). Turn your iPhone off if the battery is draining towards 0%.
To make your iPhone’s lithium-ion battery last longer, do not to drain it down completely. Lithium-ion batteries don’t have the “memory effect” that older nickel batteries were prone to have. Nickel batteries had to be drained completely because they tend to forget part of their total capacity if they’re not down to zero before recharging.
Our iPhones are our portals to our digital worlds. They are practically extensions of ourselves and our lifelines when we’re out and about. However, no matter how vital your iPhone is your daily life, it is useless if it runs out of juice.
That’s why the last thing that you need is a less than optimal, or worse, a dead iPhone battery. But are you charging your iPhone properly?
iPhones are remarkable devices, but they lose their lustre once the battery runs dry. That’s why it’s important to look after the cell inside and ensure that you always charge it properly.
