change battery without shutting down? and incorrect battery reading

[shinew]

Hi, I have a quick question and wonder if anyone could provide a solution. I just bought the triumph on VM and love it! however, the battery life is pretty bad, so I also bought an extra battery.

My question is that with the AC power connected, is there a way(software settings or mod maybe?) I could take out the drained battery and pop in the new one without having to turn off & then turn on the phone? right now whenever i take out the battery with the AC power connected, the phone just shuts down automatically. thanks!

that's the way it goes. the only phone i've ever had that you could hotswap a battery was an early 90s motorola. could be midcall and swap the battery out

ah, that sucks. i thought there might a software workaround to prevent it from resetting or something...

I did notice another thing today, I charged the 1st battery to 100%, popped it out, put in the 2nd battery and charged it full, then take it out. When I put back in the 1st battery and turned it on, the battery displays as 90% full, not 100%. Which is weird and happened to be the same thing when I charge the battery from a cheapo external charger. Although the charger displays it as fully charged, the phone shows it at 90% full when it's turned on.

any idea what the cause is?

Safety measure from the Cheap battery charger to prevent overcharge? (because its cheap, and that's a bonus if it stops auto. to prevent overcharge)

that's could explain the cheap charger, but it doesn't explain why the 1st battery charged in MT to 100% as shown, then after taking it out and having charged the 2nd battery, the 1st battery displayed 90% full when I put it back in the phone.

battery calibration does not apply the same from one battery to another. i get that as well with the 4 batteries i'm juggling.

Dude my battery life lasts at least 24 hours and I uses it pretty heavily. What kernel are you all running? This is with wifi on alot, but using juice defender ultimate! Mine is actually better than it was with the intercept!

hmm... that's not quite it. I just tested it again by taking out the battery with the phone at 95%, and pop it right back in again then turn it on, it displays 90% instead of 95%. This MT is new, but i loaded the backup using Titanium Backup yesterday with the full restore from the previous phone which behaves the same way(also MT, but defective charging port). Could that be the reason? although i'm not sure which file I should skip from restoring to avoid this problem...

I installed JD too, but with my settings it can't do much because I use Whatsapp for international text messaging and GV for my everyday texts. So I left both Data & Wifi on w/ Wifi preferred.
The only thing i'm using it for is
1)location based Wifi, so that at home when the phone is in standby mode, it's using wifi instead of 3G, and it automatically turns wifi off when I'm outside.
2) variable CPU speed based on demand. although I have no idea if it does anything, but as least for now i'm not noticing any slow downs.
So far it shows 40% estimated improvement but I don't if this is accurate or not, because I have no idea how it's calculated.

i didn't catch it in realtime, but batterymix showed the battery level actually rise by itself one time.

i've been averaging around 8-10 hours per battery recently.. the calibration is pretty off. one battery goes from 20% to 0 immediately, another from 10% to 0.

I have a slight suspicion that it's caused by me restoring the system data using titanium backup. I'm doing a factory reset right now and see if it fixes the problem by not restoring system data.

So after a system wipe and restored only user apps+data, it's all good now. It seems that restoring system data was the cause. I thought it would've been OK since they share the same factory default rom(rooted) and the same hardware.
