Optimize battery life

by p_ash / November 14, 2017 4:34 AM PST

Hi,

I am really not a gadget freak, however these days I find myself surrounded by devices that are dominating our day-to-day lives. At a minimum we all end up as users of laptops, tablets and smartphones that require charging of batteries almost every day. I would like to know how to optimize the use of batteries in these devices as these days all devices come with non-removable batteries. Should I wait for the batteries to drain out completely before I charge it? And when I charge it should I let it charge up to 100% before I start using it? Will these things make any difference to the life of batteries?

Thanks in advance for your inputs.
Ashok

The Full Charge kills battery life has been debunked.

https://www.youtube.com/watch?v=2qlvgaxPztU is another take.

But drain to to bottom. Nope. Stop it. It's just a lot of bad information out there.

With modern Lithium batteries and today's designs I follow the ABC rule with is Always Be Charging.

Reason? A full SOC (state of charge) has been shown to have no effect on good batteries. The real wear comes from use and heat. Not from charging or SOC.

Occassional draining

Hi,

Thanks for your advice and the video link, though I think the Tesla batteries are way different from those in our gadgets.

Since I am a below-average user of cellphone, a fully-charged battery lasts about a couple of days on an average. However, now that the phone is more than a year old i find the battery performance has become slightly erratic. At times it lasts less than a day on regular use but I've not seen any sign of the phone overheating. What could be the reason for this?

Sorry again. Too much bad info out there.

Same Lithium batteries. You can find phones with batteries that need replacing in a year and I don't think a thing about it. I pop in a new battery and go after the next problem.

Just sharing, my 5s battery started to swell after many years. 18 bucks for battery and kit, watched a YouTube how to and I'm done.

Makes me wonder about folk that tell us you can't do it ourselves.

hi there, so about the battery, you know. all battery wear down overtime. the more charge cycle you put the battery through, the more it will wear down. different battery have different rating. you can search your battery for more information and let me know.
letting battery wear down to completly 0% would affect your battery capacity a lot, but keep using it when it fully charge also bad. so i recommed to charge it full (you can keep using your device normally, but i think you shouldn't), then use it. In other words, if you were going to leave your laptop battery in a closet somewhere, it would be best to leave it at about 50% charged capacity and make sure the closet was reasonably cool. That would prolong the battery’s life.

Again. Debunked.

Lots of tests run and the percent saved was too low to attribute it to SOC. The more likely cause is chemical/metal degrading over time.

My cellphone has removable battery

Most would think it isn't, but I replaced it recently and the battery didn't cost too much. I even have a backup new battery since my wife's phone may need it later. Google how to replace battery on each device you have and you may be surprised how many ARE removable.

how to optimize cellphone battery life

To ensure longer battery life, it is important to learn how to maintian batteries of cellphones, tablets, etc. Let's make the cellphone battery as an example. For me, I like playing cellphone while it is being charged though I know it is not good for cellphones.... But gradually I just find it fast to drain out which is within my expect. So, I think I should maintain my devices. there are few tips for optimizing battery life. First, don't charge your phones with case on because the case cover may stop heat emision and make the device heat up easily. Second, you don't have to recharge it when the power is drained out. You can charge it anytime you want. Third, don't use your phone while it is charging. That is really harmful to your phone. Fourth, unplug the phone when it is fuly charge. Don't keep it charging for a long time, or it will be overcharged. Then, when you find your cellphones are overheating, stop using it right now and cool it down by placing it on the desk. I'm now using a qi wireless charger and I just can't play it while it is charging like I used to with a USB cable. LOL. So, maybe you can also try to stop some bad charging habits by having a wireless charger?

Odd thing here.
by R. Proffitt Forum moderator / November 22, 2017 11:22 AM PST

I think you need to change that item about charging and use. Here, I have the usual name brands and have found no effect on battery life when I do that.

I did however stop using my wireless charger because it did create more heat overall than the usual cable charger.

To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and set the switch to Off. If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval.
