    I'm liking my V40 but I want to know from past experiences how well do LG batteries age? When Samsung released the Galaxy S8 they said after 2 years of normal use it would still have 95% of its battery capacity left. Can expect something similar from my V40? Just wondering since LG batteries are no longer replaceable.

    This sort of question is rather subjective. It depends on how often you use your phone, how heavily it's used, how deep of a discharge it goes through, etc.

    One of the better things to do is install AccuBattery. That will give you an idea to the health of the battery.

    I usually charge once a day at night before bed. It's usually at 25-30%.

    The answer can vary greatly based on how you use your phone. But keeping a lithium battery between 40-80% charge when possible will be best for its health.

    Ditto. Yes it means charging more often, but Li-ion batteries are not hurt by partial charges and they prefer a happy medium. For a sealed battery, this should be more of a priority since you can no longer easily swap batteries out.

    Accubattery may work fine on some phones but it showed 85% battery capacity on my OnePlus 3T from day 1 and I was still getting great battery life.

    From https://batteryuniversity.com/index....ased_batteries

    Although a battery should deliver 100 percent capacity during the first year of service, it is common to see lower than specified capacities, and shelf life may contribute to this loss. In addition, manufacturers tend to overrate their batteries, knowing that very few users will do spot-checks and complain if low. Not having to match single cells in mobile phones and tablets, as is required in multi-cell packs, opens the floodgates for a much broader performance acceptance. Cells with lower capacities may slip through cracks without the consumer knowing.
    If you look at figure 1, you'll see that none of their test batteries started at 100% capacity. Starting at 85% as reported by AccuBattery doesn't sound too far fetched considering the above statement and possible inaccuracy of the app. AccuBattery is good for getting a general idea of health, even if not completely accurate.

    25% is way too low. If you can't charge it at 40%, turn the phone off. If you use GSam Battery Monitor you can set the alarms for 80% (or even 90%) high and 40% low.

    If you're willing to root, use Magisk to root (it's fairly trivial) and install the Magisk Module (there's a Download item in the Magisk app for downloading modules) Magisk Charging Switch and set it to 80 40 (or 90 40). Then you can leave it plugged in and it won't start charging until the battery drops to 40% and will stop at 80% (or 90%), even if it's left plugged in permanently.

    I've used it before, and from what they've written on their own website about how phones show their charging and then how accubattery does what it does.
    Accubattery measures your battery health by comparing the inflow of the current and the percentage the phone is displaying. Accubattery on their website also admits that phones are lying to you about 100%, that they report 100% when actually the batteries are at 80-90% capacity. You have to leave your phone on the charger for up to an hour even when it's 100% to actually achieve 100% (which is actually bad for battery longevity).
    On my S9, I tested this a few times and the phone repeatedly reported 100% at around 2700-2800mah capacity of the 3000mah. So around 90% capacity, the phone reports 100%. So Accubattery will be off by as much as 10% in it's readings if you use that on the S9, because it will see that the phone tells it that it's 100% already, but it recorded that you only have 2700-2800mah filled, so the app will report that your battery is only 90-95% healthy even if it should have been 100%.
    To make Accubattery actually accurate, you have to leave your phone on the charger for up to 1hr after hitting 100% every time you charge, which totally defeats the purpose since doing so will actually decrease battery lifespan. And you're supposed to be using Accubattery to warn you to stop charging before 100% to improve battery lifespan.

    Which is not what's inaccurate about it. The battery health it shows you is what's inaccurate.
    I use lightflow for that alert at 90% since I can also make the LED turn green.
