Hi, I ordered a new Iphone 6s battery and installed it following the guide. (I also followed the battery calibration guide) However my battery drains really fast. When going to sleep at 23.00 and getting up at 07.00 the battery went from 100% -> 10% During the day (checking my mail from time to time; not doing anything stressing/gaming/gps …) it drops from 100% to 50% in about 3-4 hours. Could it be that the replacement battery is faulty? Or could anything else cause this battery drain? Regards Ivo
This could be a replacement battery issue. If the old battery was still decent, I would install it to see if the pattern is the same. If it is, you may have damaged something during the repair. If they have different characteristics, then it’s probably a bad replacement battery. If this is an iFixit battery, then you should contact iFixit Support and they will help you sort things out.
The fast drain of the battery is the problem there is any shorting present on the phones.If the circuit have some partial short such problem shows.You can check this first.Check all the function like vibrator,Home button with working touch sensor.While playing games that i think that is normal like.Better replaced other one battery and check.
