Comparing the Jolla tablet to a six year old Galaxy Tab 10.1 (which has constantly been on since the very beginning):
Situation 1: airplane mode on, tablet on but completely unused, no applications running
- Jolla tablet: about 3-4 days, if you're lucky.
- old Android tablet: several months, and I'm not exaggerating in the slightest. I charged it on 20 June, which is now a little under three weeks ago. Only used it for twenty minutes after taking it off the charger, haven't done anything with it since. Just checked the battery level: 89% (no typos: eighty nine percent!).

Situation 2: airplane mode off, Wi-Fi on, tablet unused with a couple of applications and background services (email accounts etc) running
- Jolla tablet: 2 days.
- old Android tablet: it's been a while since I used it this way, but from what I remember it lasts about 2 weeks.

Situation 3: tablet in constant use
- Jolla tablet: actually longer than you would expect based on the other numbers, about 6-8 hours (although this depends heavily on the sort of applications in use, as playing an intensive game or watching hi-res video will drain the battery a lot faster than surfing TMO, for example).
- old Android tablet: about 10 hours (again depending heavily on what you're doing).

Finally, the battery capacities compared:
- Jolla tablet: Li-Ion 4450 mAh
- old Android tablet: Li-Po 7000 mAh (keep in mind the actual current capacity is probably not even half that anymore)

Given that no one has a tablet yet indicates that your hunt for the issue is pretty much irrelevant right now

Jolla Tablet boots up very fast so i do switch it off after recharge to min 80%.

Somehow we need to find the max runtime by turning everything off, right? Then calculate an optimum drain/hour and can then compare to states with single running services and apps drain/hour.

What i am going to try first is if i can beat the 4-5 days with Dalvik disabled. Was it running during your airplane runtime @mscion?
What else to disable.
Is it worth to try not using airplane but switching the services off manually to rule out airplane does not actually switch "everything off"?



Would'nt it be cool if we could hint jolla where to optimize and make the existing and hopefully coming tablets last longer?

In that case, the bad battery life of the Jolla tablet has some other cause, and that cause may affect the new Youyota tablet too. If it is a software issue, perhaps Jolla can investigate and fix it, that would help both the original tablet and this updated one.
