Any way to tell? I just got a monster phone with a 22K mAh battery.

It's a pity they don't offer the option to 'supercharge' to 100, so you get extended battery life when desired, when you know you will need it. Say, going camping, or plan to use the phone a lot for whatever reason.

So can I charge my phone to 11?

Yea that's what I've heard, and I personally keep stuff plugged in

It was a recent article by iFixit, so I thought I'd share it ¯\_(ツ)_/¯

80% "software" should keep the battery even healthier...

Isn't the charge limit of the battery arbitrary? The manufacturer can set whatever target voltage they want , so it's meaningless to say they limit the battery to 80% when they decide what 100% is.

Do you have sources?

I don’t doubt the fact that they take some margin to extend the lifetime of the battery, but if we take iPhones as an example, they:

• charge at a slower rate when nearing 100%
• try to postpone charging the final 20% until the last moment before disconnecting from the wall outlet
• can be software capped at 80% by the user (in newer models)

This makes me suspect that that the margin between what’s reported in software as 100% and the actual capacity of the battery is less than 20%. This also makes sense from the standpoint of the consumer expecting a long battery life on their expensive high-end device, putting pressure on the companies to make the margin smaller and the charging algorithms smarter. Just my observations, of course.
