Sorry but I really don’t understand this obsession over battery life. Not ranting but just trying to understand if I miss anything.

Batteries are expected to deteriorate over time right? If you’re lucky to have good battery life after having the phone for a long time then that’s good.

But if your battery deteriorates there’s always the $99 replacement and it’s FOC if within 1 year warranty. $99 is 5% of the cost of a new phone or even less than 5% if you have higher end/capacity phones. Chances are most here will change phone every 2 years or less costing slightly around $2k (before adding accessories like screen protector, multiple casings) before their battery reaches 80% of original capacity.

So what’s really the issue about battery life? Please enlighten me.

Subjective.

Some people are anal about the numbers and some people prefer to use that as a benchmark when buying or selling used phones.

Some people mentally prepared to use the phone to its fullest extent (100%-0%) and just change the battery after 1-2 years.

Some like healthy charging habits to prolong the use of the phone over a span of 3-5 years without feeling a decrease in battery life.

Just enjoy the phone since you paid so much for it.
Imagine buying a Ferrari and driving it only in a multistorey car park (unlikely analogy i know) or pumping the cheapest petrol because scared of the cost

Able to fetch higher street price and more people willing to buy a 100% battery health phone as compared to 80% when trying to sell it off.

I guess the price difference for selling a battery with 100% capacity must be considerably higher than the $99 replacement fee Then.

RWM shop cut the trade in price by $100 because my iPhone 11 Pro batt healthy was below 90%..

Just sharing, I adopt healthy charging habits (20%-80%) so that I can sell the phone at a "better" price after a couple years of use.

Although it is enticing to just use the phone from 0%-100% because:

• newer phones software shuts the batteries before it goes into critical state and will prevent the phone from waking up until a set minimum charge is met, this way
• optimised battery charging (Apple) prevents batteries from staying at full charge (actual 100%) for too long by only continuing the charge to 100% when it predicts its user unplugging it soon after

Perhaps someone can volunteer (maybe I will, but can't see myself letting the phone die as a matter of habit) to try and report results after one and two years of the above. After all ~$100 for a new battery isn't that costly as some have mentioned.

Not exactly, the percentage just gives the seller more edge and cost in resale market.

But then your net gain will only be $1 if you replaced your battery

Haha I was trolling lah
Actually the percentage shown is not really zhun
Have to do the adding of screen on time before you charge the phone

Now I understand. I don’t have the patience to deal with direct buyers so I usually just sell it to a shop. So far I haven’t been lowballed like what @keemmeng experienced even when I sold off a phone at 85% battery health recently maybe because there wasn’t a single scratch on my phone at all.

I’m more particular about the physical condition of my phone

Right, you’ll resonate if you had the same experience as these individuals. That’s why it is subjective.

Watch if you'd like to hear and learn about li-on batteries.

 

[tohchr]

There's no right nor wrong on how we used to charge the phone. It will be a never ending debate.
Suggest to stick to IP13 discussions. Cheers..

Really? I recently sold my 11 Pro Max at RWM and the guy did not even mention anything. Battery at 88%

I was with a friend also, he witnessed it.

 

[roastedcoffeebean]

For this, I agreed. I used old slow charger for my 11PM, 12PM and now 13PM. When sold away 11PM and 12PM, the battery health is still at 100% coming a year from launch date.

My charging habit is, by the time when I reached home, normally 2 hours before my bedtime. Regardless how much battery left, I plug in to charge it to 100% then unplug and go to sleep. Morning woke up usually still at 100%. This is somehow my daily charging routine for years and never had an iPhone drop below 100% during annual sell and buy newly launch iPhones.

do u usually sell before or after new iphone release?

What does Background App Refresh mean? Background App Refresh allows your apps to check for new content and update even when you’re not using them. This is intended to save you loading time when opening up apps, as the latest information should be ready and waiting after being refreshed in the background. However, allowing all your open apps to continually update and refresh in the background is a sure-fire way to drain your iPhone battery.

As I understand, yes and no.

It depends on the app developer who sets how often it should pull data in the background. It is not always doing so, so battery drain might not be that big a deal unless you have many many many apps in the background.

Developers have no control over background app refresh.

Basically, imagine your apps as passengers, iOS as the bus driver and the iPhone as a bus.
On a long trip, the bus will waste a lot of fuel and time if it keeps stopping whenver someone wants to go for a bio-break.

In the context of background app refresh. Say in the scenario where the user is using Safari to browse the web. The bus driver (iOS), sees that there’s active user interaction with Safari. It takes this opportunity to tell everyone on the bus. Okay, there’s a toilet nearby. Who wanna go?

This in turn saves fuel and time. And the upside is everyone gets to go toilet (fetch their content).

How often does a background app refresh is determined by iOS. One of the factor it looks at is how often the app is used by the user.
