Every fast charge heats up batteries, which shorten their life. In a world of non easily replaceable batteries, I'd rather charge them in 2 hours to make them last as long as possible.

  phones quickly become outdated before batteries die.

    Not necessarily. Smartphones have reached a level of performance and maturity that I could easily use one for 7 years if it wasn't for the planned obsolescence. But, somehow security updates stop arriving (even for Lineage). My next handset will be a Fairphone. At least they seem to be doing what they can to keep their devices running [1]. Apple is doing better. My SO has had their iPhone SE for 5 years now and updates keep coming.

    I keep mine for 5 years on average, and pay a little more for a model that will work reliably with an open-source ROM in case the manufacturer ceases support (or when I've had enough of their bloat).

    As a idiot Huawei customer(I really can't describe that differently) I agree, but it's not the hardware which gets outdated, just the software which gets locked away. I really wish phones had to be bootloader unlocked as legal requirement in EU(even better with hardware/driver reference/blobs/sources) .

      Feel your pain. Got a Huawei phone mid 2018, without knowing that a few months before they removed the option of unlocking the bootloader (I was under the impression before, that all Android phones could be unlocked). Granted, this was just a quick replacement phone when my previous phone just decided randomly to die one day. At least at the moment it seems that Huawei is an outlier, no such issue with Xiaomi phones.

      Is there a brand you'd recommend instead?

        Pinephone, Librem 5, Fairphone. The first two aim at being secure and trustworthy, at the price of losing Android, which is not a big issue for many users. The latter aims at sustainability, has removable battery and is modular, expandable and repairable, but runs Android with all its drawbacks. There are options however to purchase it (along with other "normal" models) with /e/OS preinstalled which is a De-Googled Open Source version of Android. https://www.pine64.org/pinephone/ https://www.pine64.org/pinephone/ https://puri.sm/products/librem-5/ https://puri.sm/products/librem-5/ https://www.fairphone.com/en/ https://www.fairphone.com/en/ https://esolutions.shop/ https://esolutions.shop/ edit: Both PinePhone and Librem 5 also have a replaceable battery and can be repaired to some extent. There are also spare PinePhone mainboards and other spare parts for sale at Pine64 site. https://pine64.com/product-category/smartphone-spare-parts/?v=0446c16e2e66 https://pine64.com/product-category/smartphone-spare-parts/?...

        Haven't had these issues with the one plus 3t, so one plus it is for me
- fatboy93 5y ago
  Sure, but as long as the phone works productively, I'm able to send messages or browse the internet in a pinch, that's all I need. Fwiw, I still use my old Honor 8 and my wife her Redmi note 5 as a daily driver.

  They uses graphene-enhanced lithium-ion Battery. They claimed their battery remained at over 90% capacity after 800 charge and discharge cycles. If it is as good as they claim the battery can easily last 3-5 years in normal usage.
  - m_mueller 5y ago
    Wow. If that's the case maybe one should start giving more credit to Chinese companies when it comes to fundamental innovations. Looks like display tech and batteries might be the first areas where they are going to be at the forefront.
    - Bayart 5y ago
      On both counts you should give credit to the Koreans more than the Chinese.

        So are we supposed to thank the the Turkish for bringing out Pfizer vaccine?

        Yay, nationality-based pissing contest... Out of curiousity, this is the earliest research I can find about graphene in Li-Ion batteries: https://pubs.acs.org/doi/10.1021/nl800957b https://pubs.acs.org/doi/10.1021/nl800957b The researcher names are Korean, Chinese and Japanese, and in the "Supporting Information" window they were affiliated with 2 research institutes in Japan.

        It’s actually an interesting parallel to how high tech hardware worked 30-40 years ago. Back then you often had fundamental research coming out of the US and brought to market from Japan, as their manufacturing base somehow allowed for more efficient productization. Looks like it has shifted to Japan now being still strong in research, but the manufacturing base is now strongest in China. One thing that I think is so remarkable about Elon’s ventures is him showing that there’s nothing stopping you still to build mass manufacturing efficiently in the West.

  That's why I avoid Qi wireless charging. It's neither fast or soft for battery.

Xiaomi is breaking headlines but they can't even fix MIUI bug since ages...
