Since the update last week, my phone battery doesn't even last half a day. I took if off the charger at 6:45 this morning, at noon it was alerting me to 15% battery left. I charged it 3 times yesterday to get through the day. What gives? Has anyone else experienced this?
My battery is draining fast as well without any OS update. Have you tried wiping the cache partition? Often that will fix battery problems. With the phone off, touch the Volume Up, Power, and Home keys at the same time. The phone will go into recovery mode. Use the Volume Down key to highlight Yes to the Wipe Cache Partition. Click the Power key to execute the action. After partition wipe is complete, select Reboot and press Power to execute the reboot. Hopefully, this will help.
I stopped into the VZ store last night since my phone went from fully
charged to 43% battery in under 2 hours. The update set my phone to Global
network. The person at the store changed it to "LTE/CDMA" and my battery
suddenly showed 78% left. He said it was the 4th he'd seen like that
after updates you need to check everything, you may be getting notifications on everything.
the last update changed my ring tone + a few other things.
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?
Many say that wiping the cache partition can help with battery drain. Unfortunately, for me doing it made the battery drain worse. My S7 can be at less than 50% after about four hours, with very little use. After just 2 minutes this morning it was down to 96%. My wife's iPhone is at 75% after a 8-10 hours and moderate use.
I'm having the same issue as wel since the last updatel. Even better, I have an S7 Edge and an S7 work phone, and both are draining in 4-5 hours. My Verizon Gear S2 drains in about 2 hrs now instead of lasting all day. I don't pay for the Verizon network service on the S2.
I've wiped the cache on both phones multiple times. As mentioned above, I checked my service, it was set to Global, so I changed it to LTE/CMDA but it hasn't helped at all. I also cleaned my cache afterwards... The only think I haven't done is wipe it. I just did that on my S7 Edge about 6 weeks ago, and really don't want to go through that again. Has anyone found a fix yet?
I was able to determine that Outlook was causing my issues. I read it on another forum, so I decided to try it since I had it installed on both phones. After uninstalling it, I immediately noticed a difference in charge time, then found the battery drain issue was gone. I uninstalled from my work phone, and the issues are also gone.
Hopefully this will save someone the headache of dealing with this.
