New replacement battery quickly drops to 7% and stays there, why?
So i got my replacement battery installed yesterday and i charged it to 100% and kept using it during the evening without any problems. The battery drain seemed fine from 100 down to about 50 % and then suddenly made a quick drop down to 7%.
The wierd thing was that i could keep using it for a couple of hours even though the percentage was slowly dropping. It stayed at 7% for a really long time. I watched 45 minutes of live football, did a little bit of web browsing, watched some youtube and worked in photoshop a little while. All of this from 7% down to 2% when it entered sleep mode.
Is this due to bad battery calibration or is it a faulty replacement battery? What do you think? It feels like i got a good amount of uptime from one charge but the percentage was way off.
Here is a screenshot from Coconut when it’s fully charged.
Ok so i just reached 7% again after playing a youtube-clip for a couple of hours and playing in photoshop meanwhile.
This is what Coconut reports at the moment. The percentage dropped in two steps really. It dropped normally down to 41% and then it dropped rapidly to 29% and a few moments later down to 7%.
Can bad calibration cause this type of behaviour or should i suspect the battery?
