For ages now, I’ve been highly suspicious of the frankly awful battery life on my OnePlus Pro 9 device. Over time, the battery life has become hugely problematic, and on average, I get around half a day of usage before I need to charge it again. Yes, I’m a power user, but I don’t use this device for video streaming or games, so it’s not as though I’m asking the earth in terms of reliability and performance.
As my contact is coming up for renewal, I started looking at the OnePlus Pro 11 - with it’s outrageous price tag, I decided to look elsewhere, and am currently waiting for a Samsung S23 Plus to be delivered (hopefully tomorrow).
It seems that this has been an issue since it was identified in 2021 - OnePlus evidently deliberately “throttles” the performance of apps such as WhatsApp, Twitter, Discord - in fact, most of them in order to “improve” battery life on the OnePlus 9 and 9 Pro phones 
There are two articles I came across that discuss the same topic.

Having to discover this after you buy a supposedly “premium” handset is bad enough, but OnePlus themselves kept this quiet and told nobody. To my mind, this is totally unacceptable behaviour, and it means I will not use this brand going forward. The last time I had a Samsung, it was my trusty S2 which literally kept going until it finally gave up with hardware failure meaning it wouldn’t boot anymore. I could have re-flashed the ROM, but consigned it to the bin with full military honours 
And so, here I am again back on the Samsung trail. Sorry OnePlus, but this is a bridge too far in my view. I faithfully used your models throughout the years, and my all-time favourite was easily the OnePlus 6T - a fantastic device. I only upgraded “because I could” and I’m sorry I did now.
Here’s to a (hopefully) happy ever after with Samsung.
Any help much appreciated. Thank you in advance.
