I know that it has been discussed before but i decided to have a fresh thread to report one thing that has been bugging me for some time.
Now i think we have all experienced the issue where the TP battery slowly drains even when it is completely shut off, this really does not make much sense to me. For me it seems to drain about 4-5% over say 10-12 hours even when shut off. That is about 10-12 % per 24 hours which is a bit too much in my opinion. I consider this issue important for two reasons. First of all it means that when you do need to use your TP you have less battery and secondly, it means that you are forced to charge your TP more often which takes its toll on battery life. And since the tablet has been discontinued and is not exactly replaceable (not by the common user i mean) this will start to matter as our TPs are getting older.
Now, i bought my TP second hand from ebay. I am from Greece so it took about 10-15 days to uarrive. The previous user had factory reset it to webos 3.0.4 so the TP was clean. Although it took about 2 weeks to come, when i opened it the battery was charged to about 95%, that means it had dropped only about 5 % in a 2 week period. Even if the indication was not correct the drop was no more that say 10%, i am sure of that since i do not recall having any issues. That is a 0.5-1% drop per 24 hours which is a large difference compared to about 10% per 24 hours which is what i have experienced since then.
Now as i mentioned the TP was second hand so we can assume that the change in its draining behavior does not have to do with going from from "new" to "used". Now one of the first things i did was update to webos 3.0.5 (i actually received the tablet around the time the 3.0.5 update came through). Unfortunately i did not know back then that this was an issue so i did not take any notice of battery drain when the TP was shut off. So of course even from the very first days i tweaked with the standard patches that we all use, added lots of apps, many of which i installed and then uninstalled etc and quite some time later overclocked. Afterwards i noticed the issue with the battery drain, but since i have done many things since then i cannot be sure which could be responsible for this behavior. Is it the webos 3.0.5, is it the patches from the community, is it overclocking to 1.5 (i think probaly not because i have also returned to the standard kernel and the drain did not change), is it adding a ton of apps which probably takes its toll performance-wise anyway?
Of course i also have the latest CM9 Nightly but at least i know that is not to blame because i have had the draining issue long before i installed android. Now the reason i am mentioning all of this in detail is because i have been contemplating these last few days of doctoring, doing a complete factory reset going back to webos 3.0.4 maybe even 3.0.2 and experimenting a bit to see if i can find out more about this issue. But to be honest, the idea of having to reinstall all the accounts, apps, patches, android etc is a bit overwhelming right now. So of course turning to the community seemed like a better more lazy idea .
So first of all what do you think about all this, has anyone made similar observations? Do they make any sense? Is anyone scheduling a factory reset, maybe we could take the opportunity and see if any of my claims are real or my memory is foggy and i am making things up.
