Hi guys. I got the battery replaced, and Battery Life app shows 4% wear level (without any charge / discharge cicle). but for some reason the app doesn't show the cycles, I think it's due to the IOS version. Do you think it may have been an used battery?
Got a tip for us?

iPhone 5 or earlier New battery with 4% wear level, is it normal?

iOS apps are not accurate when it comes to battery information. Your best bet is using something like Conconut Battery app on a Mac.

Battery Life and all other apps cannot accurately measure battery charge capacity ("health") in iOS 11. You can't rely on what the app reports. Use Coconut Battery and/or realize that it isn't worth worrying about inaccurate information. 🙂

What iPhone is this? Also, who replaced the battery? Did you perform a power cycle (or two) on the battery? Is it an Apple-branded battery?

The battery was replaced in a repair service store (Iphone 5s). Actually, I think Battery Life is very accurate. I also used Ibackupbot to test the battery, and get more information and it showed 620 charge cycles, so it was clearly an used battery. So I went there to ask for a new battery. Now, the new battery shows 0% wear level in Battery Life, and zero charge cycles in Ibackupbot (even though I have completed a cycle), along with some other information:
CycleCount: 0
DesignCapacity: 1510 (Isn't too low?)
FullChargeCapacity: 1600
I don't really understand DesignCapacity and FullChargeCapacity.
CycleCount: 0
DesignCapacity: 1510 (Isn't too low?)
FullChargeCapacity: 1600
I don't really understand DesignCapacity and FullChargeCapacity.

Lets clear this up. you had your battery replaced at a non apple authorized repair shop?

Battery life and Ibackupbot are not accurate at all and are only estimates. Just because you think it’s accurate does not make it so. Trust me, and everyone else here. It’s not accurate.
The only accurate one is coconut battery as that reads the battery hardware directly.

still, showing 600 charge cycles on a "new" battery is pretty indicative of fraud.
The previous battery was design capacity: 1550 and the new one 1510. Does it means that this second battery has less capacity?
I think the apps are relatively accurate, because after I demanded a new battery and tested it, it was actually 0% wear level, I don't think it's just coincidence.

What version of iOS are you using? On your phone, it's possible that BL is giving you correct information from iOS. I forget exactly when Apple knocked out access to that data via iOS. Perhaps your phone is still on an earlier version.

Seems likely that the 600 was actually data from the old battery, if it's now showing 0.

Correct. I’m just talking about the accuracy of those apps.
Again, you can think whatever you want. But know you are wrong. Starting in iOS 10, Apple removed all indication of battery health from developers. It’s all hidden on iOS apps now and thus, it is not accurate. They are guessing based on the current voltage of the device. That’s the only thing they have access to now. The only app that’s accurate is coconut battery because it’s reading the device via lightning cable or WiFi and goes around using private APIs to see hidden information.

OP said himself he went back and got the battery replaced again.... so no.... it doesn’t
Exactly. New battery shows 0 cycles.

Where did you got that information? They removed some data from the app; cycle charges, temperature, and some other things I believe. But who tells you that the reaming information (like wear level) is not accurate?

Because they removed mAh information as well. This has been known for almost 2 years now. Previously developers of these apps have claimed this to be so.
I have 6 iOS devices, not one of them is accurate with Battery Life compared to coconut, not even close.
Directly from the developer: https://forums.macrumors.com/threads/battery-data-cycles-health-etc-gone-in-ios-10.1977954/

I'd argue that he didn't specify at any point that the battery was replaced again, just that he asked for one...but that would be taking pedantry a little too far 😉

And this discussion is interesting: http://www.rogeriohirooka.com/2016/09/01/some-api-changes-on-ios-10/#battery
I do have one iOS device that still runs Battery Life accurately. It's an iPod Touch that capped out (and was basically croaked by) iOS 9.3.5.
Yeah, it was replaced again, maybe I wasn't specific.

Four days of use, and again:
Battery Life app:
4% wear level
Capacity: 1500/1560 mah (96%)
Ibackupbot:
CycleCount: 3
DesignCapacity: 1510
FullChargeCapacity: 1500
Battery is degrading very fast according to this.
