[FAQ] Extended Battery is not Recognized correctly (discharging like the original)

---

the forum here is full with problems of people who did get a cheap chinese battery from ebay or somewhere else, that is not recognized by their htc hd2 and is discharging at the rate of the shipped original small battery.
also the forum is full with "solutions" that are NOT WORKING that WILL NEVER WORK.
this is the reason for this thread to give the people the one and only answer to fix their problem!

first of all, be sure to have the newest firmware to have the extended battery driver.
but this will only solve charging problems if you got one of the first shipped firmwares.
after that get the ORIGINAL EXTENDED BATTERY. also the 2300mah battery from the company "leicke" is working for me. (looks identical to the original extended battery, maybe its the same)
this batteries will be recognized correctly and will discharge in the right speed!


--- got a chinese "noname" battery? ---
your battery is crap like most other extended batterys for hd2. get another one, but continue reading the rest of this thread before!
i had a cheap 2400mah chinese battery before and had the same problem.
the thing is, that these chinese batteries are faking, they are normal ones because the driver of the hd2 origininally didnt support bigger batterys in the first roms.
the chinese batterys are out of date (they only added a kickstandcover) and also the capacity is mostly a giant fake!
i disassembled my chinese cameron sino battery and here is the result: its made of 2 small batteries pakaged in one frame and controlled with one chip that is sending fakedata to the phone, also the temperature is recognized wrong because it doesn't really have a sensor! it always shows 25,X°C all the time. like i said: totally faked data
tip but not a solution: if you discharge your chinese battery to 0%, remove it and put it back into the device, you should have 50% again, but thats no calibration because a calibration of this batteries is not possible!

my "leicke" battery did cost 21 euro incl shipping and is working correctly, also the high quality cover with metal-kickstand is fitting perfectly, not like the chinese ones that never fits!

dont try to fix the problem with hints and tricks or calibrations, it will NOT AND NEVER work with the cheap crappy chinese batteries! i already tested it!


i hope this thread is helping the most people with their cheap-battery-problems.

How long does the Leicke battery last by you ?? By me not too long , just a littel more than the original -.-

for me it lasts with wlan on and permanent internet using ca 10-12 hours (and still is not empty). in standby-mode many days and maybe weeks with windows mobile. (under 5-10% draining a day with phone on)
it lasts nearly the double time of the original battery. i can tell you, that the 2300mah are the real capacity and how long your battery lasts depends on your systemsettings, phoneusage etc.
i use battclock to control the current powerdraining. with wlan on it is ca 140-300mah but mostly a little bit under 200mah. so you can calculate yourself how long the battery lasts until it is empty

I'm using the licked battery too and can confirm that it works correctly with the hd2. With current android builds the battery last for 3 days with moderate use. If you can live with the bulky shape, the leicke is definitely a great alternative to the official HTC extended battery. Cover and stand are also quite ok, aluminium cover would be nicer but can surely not be expected at such a low price.

I bought off ebay for $14.00 US shipped and it works perfectly. The back cover fits like it was made for it. Snaps on cleanly and has never come off or stick up on the edges. The battery charges with Android and WinnMo to 100% and lasts for days. Most of your charging problems may be your rom or radio version. There are probably multiple makers in China so some may be better than others. My Cheap China works works okydoky!

can you share the companyname and capacity of your battery? many people are interested in that

Here is the current link.

It has gone up a little bit. Just bid on it to get the cheaper price. There are several in his store. I got mine several months ago. Just buy a cheap silicone case and cut a hole for the cover to stick through on the back. Works good and looks fine. Only HD2 snobs will know any difference!
