Android vs iphone: battery life?

[ThisIsMe]

Traded my iPhone 14 for a galaxy s24. My iPhone could go an entire day of usage and wouldn't have to charge the battery. This android, with the same usage, has to be charged about mid day. Granted, this android does have battery protection and I have it set to only charge to 80%, but still, half a day and it's out of juice?

Is this normal for android?

Why would you only charge it to 80%?

Why would you only charge it to 80%?

It's a battery protection feature. I guess they say that if you charge to 100%, it lowers lifespan of your battery. So they recommend only charging to 80%

Interesting. I always charge my li-ion batteries fully after draining them fully. I have some as old as 20 years old still going strong. Maybe it is something in cellphone batteries, or maybe they are just trying to get you to need to replace your battery (or cellphone) more often.

IMO (as an electrical engineer) the real harm comes during the charging. The less often you need to charge, the better. Charge slow and charge long.

Ive got an IPhone 14 and yeah, the battery is excellent. I had a cheaper iPhone SE (or something like that) before the 14 and battery drained fast if I listened to music for ten minutes..

What are you doing to drain the galaxy so fast? Music? Netflix? Or just basic internet stuff like this place?

i have a 1plus android phone that is seven yrs old and going strong.

Don't know. I was doing some reading. They said not to charge over 80%, and also don't let it get too low as well I think.

They also said it's not good to leave the phone on the charger all night. So they now have battery optimization features, such as, you can leave it plugged in all night but it will stop charging when it hits 80%, and then it will drain down to a certain point before charging again. Something like that.

Also,the chargers you buy now are fast charging high amp. I think this android will charge from 15% to 80% in under 2 hours

That is what they say but I regularly drain certain lithium batteries I have past the empty mark to where I let them soak a bit and keep draining them more until exhausted and they are still going strong after many years!

I find this improves their capacity!

But who knows, maybe they now make a different, wimpier type of battery now for thin cellphone design that shorts out if drained that far.

I've also left lithium batteries sit for YEARS with no charge in them. No problem.

So, I do a lot of driving, and rather than pay for a Sirius subscription for my vehicle, I just pay for a mobile subscription that I can move between my work truck and my personal vehicle. So I have that running through Bluetooth all day.


But, I did the same thing with my iPhone, and the battery was MUCH more resilient. It would last me all day and still have 20% left. This android will be at 20% by mid afternoon, which is why I'm wondering if that is normal.

Maybe android had many more background processes running than iPhone?

Maybe it's a difference between old technology and new?

I can only tell you this: I've worked in the product design field and I know that much of what they tell consumers (and sell them) from the marketing branch of the business, is based on repeat sales through designed obsolescence. I would only ask you this: if these batteries are harmed by being fully charged then why don't all phones have that cutoff feature (it is easy to do)? And what of car EV lithium batteries? Why are they not limited to 80% charge?

The total discharge is easier to understand as a full discharge might cause a breakdown of the dielectric potential (memory of the battery to store + here and - here), but that can be restored to most batteries (ie, reforming an electrolytic capacitor).

Also,the chargers you buy now are fast charging high amp. I think this android will charge from 15% to 80% in under 2 hours

Yet a slow charge is so much better for the battery. Fast charge is only for impatient consumers.
As someone once exposed to the consumer product design industry, I've learned to only trust 20% of what they tell me and determine the other 80% for myself based on knowledge and experimentation. But YMMV.

It’s pretty normal. That would be a big battery drain. Maybe recharge to 100% to help it a bit?

True on the planned obsolescence, and it could be that the 80% feature is part of the plan to ruin phones pre maturely.

As far as why all phones don't have it, I assume because it's a new feature?

I'll turn it off and see how that works.

This is what it says. I'll move it from maximum to basic. Basic stops charging at 100% and doesn't start again til it drops to 95%

I'm assuming this is better than leaving the charge on it all night long?

I don't buy that. I was in electronic design and trust me, making a battery saver feature is nothing and if true, was known as far back as they started using lithium. After all, products which don't last don't become popular and sell well.

I'll turn it off and see how that works.

Let me know what you find.

All of the above is meant to simply prevent overcharging, which is bad for ANY battery. As for the 100% charge shortening battery life, my guess is that a full well charge simply INCREASES the chance for a defect in the battery to rear its ugly head and cause the battery to fail, so it is less about the full charge being BAD for the battery, and MORE about it increasing the chances of it finding a defect in the battery cell isolation.

I just looked at some of the other settings.


Under the power saving screen, the options are:

Turn off always on display (mine is set to on)

Limit CPU speed to 70% (mine is set to on)

Decrease brightness by 10% ( mine is on)

Limit apps and home screen (for maximum power saving, allow only selected apps, limit all backgrounds activity, turn off edge panels and change to a dark theme): mine is set to off.

I dint recall setting any of these. Not sure if that is overkill or what

 

[ThisIsMe]

So, I turned off the batter protection or at least set it to the basic level and did help me get a longer day out of it. Letting it charge to 100% obviously gives it more juice.

Well see how it goes!

Li-ion batteries do not recharge after being fully drained. They are dead. Never fully discharge a lithium ion battery. It will go into a deep discharge state and never hold a charge again.

Never let it get below 3 volts.

Flagship phones are usually not the best when it comes to battery life

my Google p8 pro is a battery sucking whore
My Samsung tablet is the is the s 8 ultra

I've had it since it came out .the last couple weeks I've noticed it it hasn't been holding the charge as well as it used to and it could run for a long time.

I'll probably trade it in for the 10 in the next couple of weeks or maybe tonight if I feel like it...
Samsung has a great trade-in program though youll get a really good deal when you trade in your s24 in a year or two

The Asus ROG line it's supposed to be the best for battery life and theyre beasts

Well, I don't know, I have lithium batteries in my two toothbrushes (2 different brands) and various sundry other small appliances, and have always discharged them to where they stopped working, let them sit a bit then ran them several more times bleeding off more and more trace vestigial current remaining until there is a sharp drop-off to near no recovery after rest before recharging them again, and some of those batteries must be pushing 20 year old easy and they are all still work just like new.
