"Main battery: Unknown" problem with 1800mah battery

---

Dear all,

I have bought 1800mah battery from easydevices.co.uk and gpsforless.co.uk and both the batteries are showing the status as "Main battery: Unknown". Can any kind soul kindly please post some solution ? I tried replacing some battdrvr.dll with some old one found in this forum , but it dint worked at all and rather started shutting down itself.

Hope someone got their extended 1800mah batteries working properly, can tell me what ROM they are using ?

Kind regards
vj

i'm using swiftblade v4.0 noi problems with the extended battery. try discharging it to zero then full charge it.

what do you mean by no problem

there is a big problem that the GPS not working with this battery

Perhaps he means without the problem referred to by the OP? As that is what the thread is about, not the GPS issue, for which there are other threads

BOT - I have this issue with 2 spare 900Mah batteries, so it is not confined to the extended battery. Am trying the drain it/recharge it option. Presumably it doesn't matter if the recharge is done when its in the phone or a standalone charger? Thinking about it, I guess it might matter a lot!

Same here , almost no GPS signal ..

I believe that the back cover face to make contacts that make better gps.
Take a test, raised the cover battery covers and try to launch such as tomtom, you will see that no locks satellites or locks them with a very long time and with a low signal, then put the cover and see which links immediately satellites and a high signal, raised again the cover and see the signal of satellites coupled fall relentlessly until you have a signal low or even absent ...
So the problem with the battery increased from 1800 I think that depends on the cover that crushes not something that runs the gps.
Why not cover the gps does not work well?

Sorry for my English ...
