High power consumption iPhone 5s

Hello,

I have an iphone 5s which has an unusually high power consumption and as a result the battery is draining considerably faster than it should. Using the app "battery health" that gives some data on power consumption, the phone consumes 140-160mA on airplane mode with all other apps closed and brightness at the lowest setting, while all other phones that i have tested (four iphones 5s) are consuming around 65-85 mA under the same conditions. Considerably higher power consumption can be observed with apps running and wifi or 4G on compared to the other phones.Recently i replaced the motherboard of one of the normally working phones with the one that shows the high power consumption and kept all other peripherals (Including screen) to check if the power consumption was caused by something outside the motherboard but showed the same result (140-160mA power consumption). The last time I tried to let the battery drain completely and recharge it, it switched itself off at 7%, was left uncharged for two days and when conected to the charger it charged normally up to 100%. The phone does not get hot neither with use nor while charging.Does anybody have any idea what could be wrong?

How long have you used it for? Have you tried another battery on it?

Yes, i have tried two or three and its always the same! I dont know its history, i got it like this and i 've only had it for a month or so.

The phone has been through soft and hard reset and set up as new and everything is still the same. Could it be a U2 or a PMIC chip problem? If there was a short somewhere on the motherboard wouldnt it be discharging even while shut off? Because it holds charge normally when off. It is very strange, I cant think of something !

If you are on iOS 12 or 11 your suffering with the battery consumption is common like others.

I have seen this before downgrade your ios if it is 12 or 11 it will use a lot of power, also turn off anything like background app refresh , automatic downloads, turn off bluetooth or wifi if your not using it
