How to care for your smartphone's li-ion battery the correct way

How to care for your smartphone's li-ion battery the correct way

It's a fact that batteries are among the most crucial hardware components of a nowadays' smartphone. It doesn't matter if your gadget runs on the most advanced octa-core silicon brain, has more RAM than an entry-level netbook, or the largest camera ever strapped to a smartphone - if your rear-positioned juicer is sub-par and fails to deliver an adequate battery life, you'd probably quickly forget about the rest of your smartphone's show-stopping features. What's more, batteries are the components most susceptible to wear over time.

Undoubtedly, you've seen many guides that provide you with battery-saving tips and tricks, but the majority of these tend to gravitate around several perpetual mantras: "turn off these features", "uninstall the following apps", "don't use these features of your smartphone", etc. If you follow all of these tips mechanically, you'll end up with a phone that's everything else but "smart", and that's something nobody strives for.

Today, we'll be taking a closer look at Li-Ion batteries and what are some tips for prolonging their lives. We'll also bust some myths that seem to still be circulating in the air.


After pointing out several of the more vital li-ion batteries properties, it's time to bust a few myths and give you tips on how to care better for the electricity-storing banks that we sport in our pockets. Most of the pieces of advice below have been derived from the data in the gallery above.

I'd rather just have a replaceable battery; I don't have to worry about following guidelines on how to manage its longevity.

who cares you will keep the phone 1 or 2 years i am on 3rd year with mine its ok still plug it in =6pm start at 630am and thats with sprints horrible service killing power with signal drain

Okay, so one question. Should one be happy about rapid charging mode that comes with their phone? Cause that's both good and bad...you can expect quick charging and expect battery life span to be short. Is there a way of manually turning off the rapid charging?? Cause that would be useful.

Buy another charger that doesn't have the same charging capabilities as the quick charge

Use the rapid charger, and get a phone with replaceable battery. Win-win!

If i have the option of manually turning off the rapid charging, having 2 charger becomes redundant.

Rapid charging should be used as a reserve. Last resort. Any current type of induction charging(As in wireless charging), causes heat increase within the battery. Once this heating starts, the battery has already been subjected to damage. Same with over using the device. Once you feel the device overheating, the damage is being done. These are some of the things the manufacturers don't want you to know. John B.

For your argument to be valid, you must tell us at which temperature the damage is being done, and how much damage is being made. We all are willing to compromise to some extend to have more comfort, in this case not having to wait for a slow charge or charging more often than needed is more comfortable.

I don't think this would do anything to the battery. QC2.0 is a smart system that monitors battery temperature and changes voltage accordingly to maintain the proper battery temperature. Voltage alone is not the problem.

For someone that has "Engineer" as a name, I find it inconceivable that you don't care that the most failed component on an expensive piece of hardware, renders this hardware useless in the event of failure. Because you haven't had an issue doesn't mean the 30% of premature device failures due to failed batteries doesn't exist. It's real, it happens and the servicing cost to consumers for sealed batteries has risen 65%. So of you are part of the 60% who haven't yet had an issue, the 30% chance you can, is still there. And what if your charging port breaks? How do you remove the battery to charge it via desktop and swap it out? John B.

60% + 30% = 100% ? By the way, where are you getting these numbers from? 30% of premature failures might be due to the battery, but how many premature failures do we have? Premature failures is in most cases covered by warranty. And a micro USB connector is rated at 10.000 insertion cycles.

In theory it works, but in reality trying to find 'genuine' batteries at a reasonable price 3 or so years down the track is a big headache.

Agree. Most of the replacement battery sold is either genuine+expensive, or fake+cheap.

$25 for an OEM samsung with charging pack (that plugs into a micro USB) from their website is A-OK with me. With one spare, my S5 can go all weekend, heavy use without seeing a charger, it's pretty nice. I know some don't care, but for me, I'm a very, very satisfied customer.

Not much of problem then since most phones have replaceable batteries any way Except replacing difficulty is an issue as most aren't easily replaceable since you have to open them up

2. engineer-1701d unregistered

why not s6 with metal bottom that slides out and u slide battery in like older cameras, or just use capacitors with slow bleed resisters on it allowing correct v out it would 100% charge in 30 seconds and last all day or 2

The capacitor size:storage ratio isn't there yet, and probably won't be for quite a while. The slide in/out battery idea would be great, but it'd ultimately add thickness and cost.

Or buy a phone with a replaceable battery and don't worry about it.

Or buy some phone casing that have a battery in it.

This is exacly what manufacturers want you to do. It is a bandaid for underlying battery issues indigenous to rechargeable batteries and leaves the expense to the consumer. John B.

While all of my phones have had replaceable batteries, I do think capacitors are the future. I have a large 5.11 flashlight that uses super capacitors and goes from 0% charge to 100% charge in 90 seconds. It holds a charge well also.

Better chargers should avoid over charging, no?

44. HSPalm

No, the charging circuit sits inside your phone. The "charger" that you plug in to your wall is simply a power supply. It has to be like this for "chargers" to be somewhat universal.

Based on image no.8, I thought li-ion batteries has overcharging protection mechanism? I always charge my phone overnight and it never blew up. I doubt about that part. Perhaps PhoneArena should mention some common myth to bust to prevent confusion.

There's no number 8 in either slideshows...

38. EcoCare

Posts: 444; Member since: Jul 30, 2014

I think they removed it. Probably because of my comment? Number 8 is the one with bloated battery due to short-circuit by overcharging (at night).

39. andynaija

Posts: 1231; Member since: Sep 08, 2012

Oh ok. Well your previous comment is true, because there is an overcharge mechanism to prevent such situation, and just like you I usually always charge my phone overnight and I've never had a problem either.

Guys I'll be honest you cant do anything really .. You can try save but you won't save that much.. Especially in iphones ! iphone 4 or 4s or 5 or 5s or 6 or 6s .. all has crapp battery ! It is so irony that smartphone manufs. will implement so many features into phone and once you have it they will tell you ; well if you want save batt. you need to turn all THOSE features off and NOT use them .. So you practically end up with basic phone for a ridiculous price.. So many ppl ABSOLUTELY not realising it !!

PA, Your guide is NEED UPDATE. While it's true that FAST CHARGE will stress the battery, NOT ALL fast charge were created equal. You need to do more research on this. BUT I help you. FAST CHARGE by RAISING the current (Ampere) will stress the battery. And it's bad. FAST CHARGE by RAISING the volt (as in Qualcom QUICK CHARGE 2.0) will NOT stress the battery. The reason of why raising the volt it's not done in the past, because to do this, it need a controller to make sure both charger & the battery know which volt will be use, otherwise the battery will go bust. I really hope whenever PA mention about fast charging will stress the battery, this little known fact will also be mention. Otherwise, PA just making a false myth that ALL quick charge is bad.

http://www.androidauthority.com/quick-charge-explained-563838/ Qualcomm Quick Charge supplies 3A on supported devices. Though I'm not really sure in the conclusion whether fast-charging will make your battery go bad faster.
