Battery issue



Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.

In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!

It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.

What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?

BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
