Right... Ok... Good to know... Can I go up to 4.8 easily... I was on 4.1...thanks for the quick reply... Plus... Is there a lineage rom/ is that an easy flash?
Follow Starbucks2010's guide on how to on the first page to update to 4.8 and you should be able to easy enough.
Sam mobile will have the relevant (FVIB) android base needed for 4.8.
It should definitely be free on there.
Not a fan of lineage ROMs myself but there is one on here.. look below / similar threads bit
Edit: just to state, it's definitely android 13 itself causing the drain and not BR. That as always is brill.
Hopefully A13 will get better as it goes along.. and according to Google I'm not alone but hopefully it's not just me on here having issues with it lol
