during charging, the charger is very very warm, but the phone is cold

So far, those who received the latest 78MB OTA, don't have detrimental issues...

However, hard/factory reset is still a must if anything goes haywire after the OTA...So be prepared for it should you decided to proceed with Nougat OTA...

I've a feeling that the CPU Usage report is "fake" in Nougat. You may need to install 3rd party monitoring app like "BetterBatteryStats" below:

The app is not free but hunt around if you will...Also, it will work better for rooted devices...

Hmmm... Very strange it is...

mansooriqbal, you still using microSD Adoptable Storage?

Perhaps second round of hard reset will do the trick...

Hard reset not Factory Reset... You know, rite?

mansooriqbal, how's the energy consumption now...? Have you tried factory/hard reset without installing any apps...?

Waloh.. .. went to play with the S8 and S8+, so sexy tempted to buy one but I read their thread owners getting 4h for s8 and 5h for S8+ sot. After using P2 difficult to switch phone lah

My hypothesis is that the phone auto-lock / auto-sleep has disturbed the backup process. Just set the sleep display inactivity to 30 minutes.

Ensure we have several backup services before hard reset.

I use Google backup and Helium.

Helium:

I believe this is normal due to FB app ... having 60% energy left is decent with 5 hours SoT... furthermore, the 5,100mAh deteriorate after 1 year ownership...
