I have a very strange problem. Semi-annual phone, Android 7, used occasionally as a spare, in most cases only the sim is active on it (no data transmission), no Wi-Fi (sometimes I turn on) and GPS, there are some applications running in the background (such as Messenger, FB, Gmail , YT, OLX and others, but without internet access, they don't do much). Occasional calls and text messages, sometimes only every few days. Until recently, the phone has a battery life of over a week, 8-9 days.
Last week it became strange that the battery suddenly started to run out of its own accord ... There was nothing changed or installed on the phone. The only thing was, when I went on tour, I turned on the GPS and AutoMapa for an hour, then I forgot to turn off the GPS, there was some Wi-Fi. In the evening I turned off these additions, the location, there was about 50% of the battery, the next day in the evening I had to top up my phone.
Since then, I have noticed this battery drain. The phone only lasts 4 days. Yesterday I was charging the phone again, at 2 am the battery was 100%, at 11 am it is only 82%, even though the phone WAS OFF all the time ... It's just paranoid, simply impossible. Previously, the phone for 24 hours did not use so much, rather around 10% ...
The phone after that weekend, when it was discharged so quickly, was restarted.
The battery analysis does not show anything either, it shows that the consumption is "lost" by several dozen percent ... I am attaching below screenshots. Until now, the screen was always tens of percent responsible for consumption, and somehow it was correct. And now everything is only 20%, and where are the rest?
First, the one after 4 days, where I only have 15% and shows 15 more hours, and then the one after today's 9h, where he suddenly used 17% and allegedly only 44h left (this is nonsense, because these 83% and 44h are nothing up to 15% and 15h ...)
