I am having the same issues.
What I have observed:
- At full charge, the battery will drain to about 20% in a matter of hours.
- At 20-30% I receive a low-battery warning, and can literally watch the battery drain at that point to 0, at a rate of about 1% per second. Translation, at 30%, the phone will die.
- I was talking on my phone, noticed my battery fell to 27%, immediately plugged it in, but before the charger connected, the phone was dead.
- I have checked and verified my app usage via app power monitor is under 15%.
-My mobile network is set to LTE/CDMA
This is either an issue with the latest updates, or a battery having gone defective.
What can we do? Will Verizon/Samsung replace the battery and/or phone?
