Hello All,

 

I wanted to put up a solution that I have found after searching these forums.

 

Symptoms:

Screen on: Battery drains 1% every 30 seconds with screen on.

Screen off: Battery drains 1% every 3-4 minutes with screen off.

 

Solution:

I "recalibrated" the battery by keeping it on until the phone died and turned off on it's own. I turned the phone back on and let the battery die again within seconds. With the phone off, I charged the phone until it showed 100% on phone off screen. With the phone not charing I turned the phone back on. After doing this my battery indicator returned to normal and I was back to seeing normal drainage:

 

Screen on: Battery drains 1% every 4-5 minutes

Screen off: Battery drains 1% every 30-45 minutes.

 

Please Note:

When draining the phone down to dead, the phone showed a charge of 1% for 2.5 hours before finally dying. This lead me to believe the batteries charge level was way off and "recalibrating" it fixed it.


Give this a try to see if it works for you.

After reading through 17 pages of the same issues - my S7 has the same happening after about 1 year.  My phone battery started draining very quickly (7am @ 100% - by 9am down to 75% while mostly on standby)

 

I did a little of what each of you have mentioned: 

 

  • Disabled the Chrome app (using the Samsung Internet that came with phone)
  • went through apps and limited the background use to only select ones
  • stopped using wifi - (think this had most to do with it) 
    • my phone only lost 4% last night over a 10 hour period
    • My phone used to get very hot - it hasn’t since performing the above (going on 24 hours)
  • Disabled Samsung+ and S Health.
  • Updated all apps through play store 

Last evening at 11 pm (Battery at 95%)

Today at 9am (Battery at 90%)

Today at 11pm ( Battery at 59%) Didnt use it much as its sunday but it certainly a drastic change in standby time. 

 

Not sure if all this makes sense as Im pretty much a novice but it seems that so far its working for me. Will update in about a week.

Same here. My s7 battery has always been great! But since the new update I have to charge several times throughout the day. I'm not using my phone differently. Very irritating
