Battery OEM Mazda or SAMSUNG

I have this car. Most important is that below -12C, the gas engine stays on, and won't let you drive around on electric alone. That accounts for several months of driving in our winters. Secondly, even in temps below +10C, you have less access to the battery's energy, so your range drops even independently from the usual cold temp range losses.

I got the Note 9 the same day as my buddy did. I was very careful about slow charging from 50% to 60% (overkill, I know) and he was not careful. His phone crapped out after 2 years but I used mine for 4 years until I decided it was getting slow.

Maybe they’ve finally fixed the Doze mode they promised? Because, from what I can tell, my battery never improved after they released One UI 7. I’ve had this phone for two years, and the battery always dropped quickly - even when it was just sitting idle. But today, for the first time since I got the device, I unplugged it in the morning and still had 50% remaining by midnight.

I would say the battery use on my S9+ is between 12-15% per hour, depending on the use scenario. Quite close to you, it seems.

It is a bit worse than I expected (coming from a Galaxy Tab s5e, which had unreal battery for its age), but everything is super fast, so not bothered too much with it. And the battery is still better than on my laptop, so it is quite useful when talking about some note-taking, e-mails and browsing tasks outside of home.

I noticed that some activities and apps (e.g., note-taking on Samsung Notes) take more battery than I hoped, but it is what it is.

Edit: Forgot to add, settings are maxed out, 120hz, bluetooth on, S Pen used constantly and charged from tablet, etc.

The only issues my wife and I have had on our 2021 CX9 and 3GT are dead battery issues. And we had dash and reverse cams fitted, which run and film continuously. If our street is busy, they can run the battery flat within 2 days.

I’ve had my 3 for 4 years and I’m on my 3rd battery.

Incan confirm they suck… i have a 2023 mazda and i have gone through two batteries. The second one died on me this week. Both were mazda batteries

Mazdas OEM batteries are horrible. Had the one that came with the car be weak so Mazda replaced it under warranty. Not even 5 months later that new battery dies, tried jumping and it was completely dead and a jump could not start it.

My'21 CX9 battery is weak, and i can clearly tell its low on voltage after sitting without being started for a week. Never tried playing music on battery though in this car.

Basically many of the oem stock items for mazda are fine, but have notoriously short life expectancy. They have to cut corners somewhere. Battery and tires are the ones I've noticed that are good for a couple years at most before they are ran through. So yeah, I've had a mazda thay needed a new battery after 2 years, one that needed a new battery after 3 years. Just how they go.
