Somehow this tablet's battery has only gotten better with age! Seriously impressed.

Have you tried power saving mode? I recently gave it a try, just enabling cpu limitations and disabling capacitative buttons lights, and I could get an extra 15-20 percent of battery light.

Using this mode on a t800 on stock Rom, non rooted but debloated, I can go up to 6h30 to 7h of sot, doing mostly chrome, flipboard and SimCity

I usually go around 5h20 of sot in regular mode

Well, I think you are right. It's not the android OS, but the apps that cause this problem. If there is any problem with Android 5.0, it's perhaps its inability to reign in the apps that keep that tablet awake most of the time. I have downloaded CPU spy and other wakelock detector, and they both showed that my tablet was not in deep sleep most of the time running either stock KitKat or Lollipop. To be honest, I never got to the issue of finding out which app was the problem, but what I did to fix this issue was to flash the latest clean Lollipop rom, and then keep the number of apps down to the must have minimum. And right now my tablet is spending about 2% of power a day while turned off. So if I have a three day break between going to gym, the place I use the tablet the most, I don't need to worry about recharging the tablet. After doing this I still noticed that Hangouts, the preinstalled system app causes the most wakelocks on my tablet. I looked around in its settings, logged out of my account, and disabled everything that looked like "update" or "sync" and that seems to have stopped that issue too.

So right now, I have zero issues with my stock rooted Lollipop.

It a shame you have to disable so much of the features of the tablet/phone you paid big money for, hopefully when we get v6 marshmallow the new feature "Doze" will improve battery life, fingers crossed.

Quote:

Doze uses motion sensors to detect when your phone’s not moving, and enters a deep sleep. The result? Your smartphone will stop all non-essential tasks such as Wi-Fi, syncs and jobs until the handset starts moving again. That means your battery should last much, much longer.

Interestingly, Doze will have control over all apps and other functions – unless otherwise stated – so Android users will benefit from improved battery life across the board.

Guys, want to share my latest result with PAC-MAN rom after trying out Ironrom for almost 6 months.
I'm so impressed by the responsiveness and battery life of the latest PAC-MAN ROM running on Android 5.1.1.

You can get it here:

Previously, I could only get 4 hours SOT max.
Now I could get more than 5 hours

Hope it helps...

After about 4 months of really light use where i would read for about an hour a week and maybe check something random for about 10 minutes during that week, i noticed the battery hasn't gotten better or worse.
Running latest official LP (rooted and debloated).

The standby is really poor from the start ( i did full discharge/charge cycles) and the battery would last about 3 days in standby where i wouldn't even touch the tablet.
I have 0 accounts syncing but WiFi is on, so i guess it does Google updates and services. I got Greenify running which gave some limited results, yet not so good.
It's a trade-off for such a light tablet i guess, iPad isn't any better so i guess that's just how it is.

I would say the battery life is certainly on the lower spectrum of popular tablets and that is kinda shame for such a gem.
