Battery Drain 100% to 50% in 3hours on stand by

[Android Central Question]

I noticed recently that my phone the s6edge and my work phone the s8 has begun suffering severe battery issues, 3 hours on standby mode has drained 50% of battery. And sometimes when in the pocket the phones get really hot. Both phones are updated to the latest software. Any solutions?

It could be an app causing the battery drain. Have you recently installed the same new app on both phones?

Welcome to Android Central! See if the battery drain also occurs in Safe Mode: https://support.t-mobile.com/docs/DOC-34283. The steps should be the same for your S6 edge.

Also review your battery use - if you usually drain the battery almost to 0%, that alone would be the cause, and they both need new batteries. Lithium batteries can't be treated like that - 40% is about the charge or turn off" point. (50% is better, but 20% is getting into the "supporting battery companies" area.)
