[GT540 Optimus General] zedshot2:
what worked for me

Hi

I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).

Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!

Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.

Pic of current battery drain:

As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.

I had 2 problems:

1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)

2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.

1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.

2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.

There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?

I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"

By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!

One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.

And you can confirm this if you unplug your phone while looking at yout battery stats.

I hope this helps

PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.
