Guys, anyone know how does battery health calculate? It drop 1% after 2 weeks. Is that normal?

How old is your phone? Mine dropped to 98% after 8 months (with 140 charge cycles) of use. After updated to 12.0 and reverted back to 11.4.1, it increased back to 99%. So, it is not 100% accurate.

Can use the desktop app "coconut battery" (macOS, not sure Windows) to check the charge cycles.

The transfer has always been perfectly fine for me . I am referring to backuptrans

The phone bought in April and it dropped to 96%, anyway to reduce its cycle?

no harm to change every two years especially using postpaid with two years contract subsidy.

Old one can just keep for spare phone.

I prefer to sell the old one to recover some cost for the new one

I am opposite. I still have 1 x iphone 4, 2 x iPhone 4s, 1 x iPhone 6 Plus as spare. IPhone X + iphone SE as currently working phones.

Still possible. You still use the same private key as long as you hold the same phone number. Backuptrans will download the messages to store locally first and then sync with iCloud/GDrive again.

Same, currently using iPhone X + iPhone SE as working phones though i sell off my old phones as these kind of stuff cant keep

Wah, nice. I don't keep my old phones though. Usually pass to my wife or sell away

I only have ip4s as spare, Ipx is my main and S7E 2nd 😁

cycle is a measue of how many total 100% you charge. so how to reduce? you can stop the cycle from increasing though.

Should I stop at 99%?

currently using iphone X as my main phone. 6 plus for secondary. and still keeping a 3gs at home.

The battery experts claim that you should keep your charge level between 20%-80% to maximize your battery longevity - but I prefer to charge it to full every time.

I notice my iPhone X GPS signal is damn lousy. Always no signal especially when i am using Waze (notice that Google Maps is slightly better). Complaint to Apple many times, they keep asking me to wait for new iOS updates and that should fix it. I am now on iOS 12.0.1 still same problem. Maybe slightly better.

At first I thought is the area that I am always in having bad signal, but when i pull my old 7 Plus out at the same time, GPS detected quick and no issue. I think the GPS chipset in iPhone X is kinda lousy for my set. Mine is the first batch from Singapore.

I must see 100% everyday! Do you think overcharged will also cause drop of battery health in faster way?

Same here

I’m quite certain charging to full every time will shorten your battery lifespan, but I think you’ll probably only see the degradation after a year or two, which is OK for me.

Actually it's 40 - 80

Haha, yeah, something around those lines
