I recently purchased this device
Best Samsung phone ever A52s 5G,
For normal use or for gaming,
Especially this Snapdragon 778G 5G processor,
I still have Android 11 and the battery lasts a day and a half for normal use,
I am using Universal Android Debloater,
I recommend this phone if you have big hands
To avoid battery drain, try this, Play Store - click on your Google icon top right - Settings - Network Preferences - Auto update apps - Don’t auto update apps. Wait for a few days and see if it is any better. If not, you can choose to revert the setting. I found this improved it. I manually update apps, once in a while when plugged in. I think, Samsung / Google should add a setting to Auto-update only when plugged in.
I never had more than 4-5 hours SOT. Others report 7+ hours but that’s just impossible for my device. I have battery 2x replaced, so as screen and motherboard, but still 4-5 hours. So it doesn’t seem to be a disaster to me: )
that’s the thing I would’ve wondered in May-June but it was working much better then.
But now the weather is cool compared to may and yet it suffers.
Can not restricting charge to 85% be culprit since I use their 25W charger, but then it’s not even been an year since I bought this phone.
