Have you downloaded any new apps or changed your use at all in the last day or two? If you go into settings then battery you will be able check power consumption and battery usage to identify what might be causing the drain.

The power is managed with the system AI. As such, the battery isn't getting worse, the system AI is just 'learning' how much you use your phone and adjusting expected battery time remaining accordingly. This will continue to change as the system get more info. 26.30 is still great and probably about the same as mine. This will still get you though a whole day and then some; better than any other phone on the market (except the P20 Pro maybe).
Hello im only not using batery saving mode, but the problem is that i also notice that during the night batery drops 4 percent what was not happening before. from the first day of use i have same aps on my phone. Yesterday i downloaded new one and i delite it but no change. From 100 percent and 31 hour of batery i dropt on 26 30?! My phone is 5 days old

Hi @IvanDinic

Yes, that's right. When you use your phone for the first time it doesn't know what kind of user you will be (light, moderate, heavy) so gives an estimate on how long the battery will last. Once it has information on your usage it can then give a better estimate. This will continue to change as your usage changes but should settle on the right estimate for you. Even for a heavy user this will still be sufficient to give you a full day.

Losing 4% overnight isn't much at all (my iPhone used to drop around 10/15% overnight) but if this has increased then it may be due to some app activity still running overnight. As I said, 4% is pretty normal so I wouldn't worry about it.
Thank you Jmoon. I will continue ti track whats going on. This was real intriguing about AI. Ok lets see what will happen.
Thank fir the support!
Hey here is un update, i turn off automatic app lunch also turn off majority of apps not to work in a background , clear the cash and now batery is workink again in full capacity.
