When it told you to charge the battery, you plugged the charger in. When it was fully charged you used it, waiting to charge it again until you got the message to charge it again.
In most phones, that message comes at around 5%-10% of charge. Discharging a lithium battery that far will give you a lifetime of about 300-500 charges, but the battery will start losing capacity long before that.
Now you use the phone until it tells you to charge the battery, right? Wrong. Try to never (except, as you'll see later, during conditioning*) let the battery get below 40% charge. Letting it get below 50% is where the lifespan starts dropping. 40% won't shorten the life enough to matter. 20%? Half the life. 5%? The battery probably won't last a year.
Then they wouldn't be able to sell so many batteries (at inflated prices, compared to what distributors sell them for).If it's so harmful for the battery to be discharged past 40%, then why don't manufacturers make the "please charge" message at 40% rather than 5 or 10%
Or from researching lithium batteries on the web.It seems that users are likely to be unaware of the batteries' vulnerabilities, so the only source of instructions/information they can get are from notifications or messages from the phone.
Not really. I've had many people complain that they can't get through a day on 100% of the battery's capacity, so they definitely can't on 60% of its capacity, but they were going to get as much use out of the battery as they could (meaning discharging until the phone shut off). Then they complain when the battery dies (totally dead and unchargeable) after 3 months because they want it to keep going, full 100% to 0%, for the two years until they buy a new phone. (Which, of course, is unrealistic - but they don't want to hear that.)If the messages are given at supposedly the "right point", according to what you claim, that is, at 40%, then users are more likely to abide it, avoid discharging past 40%, and charge it.
Not unless they've been told here or on some other site.At the end of the day, it isn't really the users' fault that batteries die so quickly
Remember, the world isn't run by "right" or "nice", it's run by "how much can I make, honestly or not?" The manufacturers don't care if you have to buy a new battery every month. Why do you think there are so many phones now that have non-removable batteries? It costs you $10 and a minute to replace a battery. You pay them $60 for that. That's another $50 in their pockets. (Actually more, since they don't pay retail for batteries. And why I haven't upgraded my phone in 4 years. My next phone will have a removable battery, the same as my current, over 4 year old one does. I'm just waiting for a flagship phone with a removable battery that can be rooted.)These issues can easily be avoided if users are given the appropriate information.
Then they wouldn't be able to sell so many batteries (at inflated prices, compared to what distributors sell them for).
They both use Li-ion batteries, but it may be possible that Apple sources a different manufacturer with higher standards (Then again, there isn't many battery manufacturers in the first place). Or you could just be lucky. All these suggested practices are based on averages, so some people will do better and others will do worse.Are iPhones and Androids inherently different? I never let my iPhones get low but charge them every night overnight. After 5-6 months with my iPhone XS the battery health was still at 100%. Though the iPhone and most Android phones now have sealed batteries, I only take this charging habit stuff into consideration when I'm using an Android device.
Maybe it is, in fact, an Apple thing. I've charged all my iPhones that way and since the introduction of the battery health in settings, it had never dropped below what it was when I got the phone.They both use Li-ion batteries, but it may be possible that Apple sources a different manufacturer with higher standards (Then again, there isn't many battery manufacturers in the first place).
