Removed battery short, batterytime decreased!

[Guest AvWijk]

For some serveral reasons had my simcard out of my MPx200 and installed in another phone for a few hours. Later, I installed the simcard and the battery back in my MPx200. Everything went fine, but I noticed my battery time increased, after an hour my battery was at 80%, and before that I fully loaded it :roll:

Before I had the battery out everything was fine, battery time was about 3 days. Now not even 1 day! Now I do have to hard reset my phone AGAIN :twisted: This matter happended before when I went to the discotheque where I had somehow 0,0 network coverage. Before I went I loaded the battery to 100%, batt time 3 days. but when I went back out of the discotheque, my battery was dead. After that I charged my phone, and I'll get a shitty battery time back of 1 day :cry:

I'm getting VERY VERY tired of this battery life s*** and hard resetting all the time, I can't even normally pull out my battery because I get worried about an battery life decrease!! :twisted: :evil: :evil:

By the way I have @nonymous: WM 2003 , latest version before I didnt had any problems like this

[Guest chudy]

well i had battery problems for a while now, never used the mps200 with SP2002 so i cant compare it with that (only bought the mpx200 because of @nonymous's WM2003 rom :D)

what i did and it seemed to help is take the battery out and totally discharge it, i dont know if its bad or not but after i did that and fully charged it overnight, no longer had the short battery life...maybe it was a fluke so who knows....

so i took a light bulb out of a flashlight and connected it to the two ouside battery leads, and after it went dim and then dead, i did the lick test to see if the battery had any "kick" to it :P. being totally discharged, i recharged it and everything seemed to be well again...

I didn't have any problems like this with Smartphone 2002, anyone else?

Very bad thing to do :P

Li-ion batteries do not suffer as much pronounced memory as the old

Ni-Cd and Ni-Mh. Fully discharging it can damage the internal circuitry

of the battery and reduce the life of the battery.

Best thing to do with Li-ion batteries is to charge them with a good

12 hours plus once in a while and they prefer to be topped up rather than

drained.

Actually, it's even WORSE than that! :shock: Discharging a Li-Ion battery below 2V (per cell) makes irreversible damage to it's chemistry! Internal battery electronics should usually be designed to prevent such an event, though, along with overcharge (Li-Ion batteries, unlike Ni-Cd, Ni-MH and many other technologies do not have an "inbuilt" chemical mechanism that protects them from overdischarge and overcharge).

Bottom line is - if your battery voltage is above 2V, you're safe.

Thanks all for the replies. I have the feeling that if I take out the battery some setting or register thingy for the battery is resetted, causing worse baterry time. Isn't there any software solution for this?

[Guest orcinus]

Sorry in advance if this won't be of much help, but have you tried cleaning the contacts of your battery?

Although it may sound weird, but once, when i had a Siemens S35, i had problems with battery that seemed to stem from miscommunication between the phone and battery electronics. Cleaning the contacts and lodging a thick piece of paper between the battery and casing (so that it presses the battery against the contact leads) helped.

i pulled the battery out of my mpx200 numerous times and never experienced the problem you've described... :P

It didn't work :cry: My MPx200 hardware is ok. It looks like it's a software problem, I didn't had any battery probs before. I'm tired of hard resetting again. Re-flashing the phone, shouldn't that be the solution?

[Guest muzzio_giovanni]

with my mpx200 and windows 2003 i think that my battery is die because the charge process don't start : the battery is empty ( infact i can't turn on the mpx200 ) and the charge don't run in anyway

[Guest josephccy]

i have found that. when my battery totally 0%, Backup battery is 90%. i still can start my phone, & then i check the Resource Manager, that side show me that my battery is charging! But i dun have charge my phone at all. how come will be like that?!

[Guest awarner [MVP]]

Try charging with the mains charger and the phone powered off.

Same here. When my battery is 0% the display shows "charging Battery" icon.

[Guest Rivernet1]

Wow - I guess I'm not the only person w/ this problem.

When my MPx200 was running WM2002, my battery would last a couple of days, and since the installation of WM2003, if I can get 10 hours, I'm lucky.

Then again this thing keeps locking up and acting strange at times. Wonder if it's a hardware issue. :)

[Guest awarner [MVP]]

Did you make sure your battery was fully charged when you did the Hard Reset? if not recharge the battery to 100% then hard reset :)

[Guest Rivernet1]

Yup. Actually, if it was charged anymore, it would glow in the dark.

heh heh

PS - I also have a 'packaged ROM' archive and I wrote the instructions on how to go about the flashing and etc, etc - and I mention in there "Make sure your battery is 100% charged, not 90, 80, or somewhat - it needs to be 100% ready to go."

So.... Yea... it was 100% :)
