Battey Dies At 14%

p.s when talking about baterry does anyone knows or had one extended baterry which says 3500mah which is around 10 dolars on ebay ?

I notice the 3500mah batteries come with a different cover as the batteries are bigger - I'm not sure I would want to make my sleek phone any bigger!

There are other ones like this one that offer greater capacity for the same size.

Anybody have any experience of these? I must say my experience of buying electronic goods off eBay has been poor! That said, I did buy a great replacement battery for my old iPod which was much better than the original.

i would definitelly buy one if i was in the states to see if there are some baterry improvements but too bad for me i live in the great Macedonia
 
I wouldn't recommend using third party batteries, especially extended ones. I've always maintained the view that if HTC could have crammed an extra 1500 milliamps into the Desire battery without affecting performance, they would have. Sounds a bit dodgy / risky / silly to me :/

---------------------------------------

I've done the power thing. So far so good, just need to wait until it completely dies on me again before I report back.

On a site note, the devs @ Miui have done some serious work on their ROM in the last few versions. I have always maintained that Redux was best. But this version of Miui easily matches that, if not surpasses it.
 
my phone shuts down at 13% going to 12% and i have done the calibration without deleting the baterry stats

i am going to try tonight the calibration method with deleting the baterry stats if it will make some change

mine says that the baterry condition is good when pressing * # * # 4 6 3 6 # * # *

I don't see any problem with getting another battery with greater capacity - have done it before for my iPod and laptops and the replacement batteries are always way better than the originals.
 
I also don't accept that it is normal or correct for the phone to shut down at 14%. Mine used to shut down at 1% or 0% - that's when my battery has run out so I expect it to shut down then, not when there's still 14% left! I only started getting this issue after rooting and installing Cyanogenmod 7.

If the battery needs to retain some power so it won't break then that's its business - I don't need to know about it since it is no use to me! I don't buy that it is normal to shut down at 14% since it didn't do this when I had the stock Froyo installation.
 
Great news....

The calibration method worked. I've tried it twice now over 2 days and I can now report that my battery turns off below 1%.

Just look - 4%.
Yesterday, mine went all the way down to 1% and stayed there for ages before finally conking out :)

If anyone is interested, this is what I did.

1. Use the phone until it pops up with the shutting down pop up which you cannot stop.
2. when this happens, plug in your charger.
3. Do not turn your phone on, wait at least 6 hours (overnight is ideal).
4. Turn your phone on and it should now be calibrated and turn off <15%.

I didn't even wipe battery stats. So happy :)

see now I don't see that as 'calibrating' but just as, charging the battery with the phone off, which to be fair I can't see really doing anything more than charging normally.

And also the whole "wait 6 hours" thing as well...as when batterys are full they will slowly discharge and trickle charge to avoid being overcharged. But this is much the same as when the phones on as well, the only difference is its quicker to charge when the device is off.

But I still don't see it being a way to calibrate it...much the same way as I don't really see the "charge it off till green, then turn on charge till green, turn off etc etc" method that is also floating around as well.
 
i think calibration helped me too but i am not sure still i will wait for it to power off and report

when i charged my phone when it comed around 90% it automatically jumped to 100%

is it good to delete baterry stats when changing rom ?

i read it somewhere to delete everything but i think that's when it mess up my baterry

You are probably correct with all of this.
But regardless, it doesn't really matter to me.

All I know is that that is what I did, and now I have gained my 15% battery back. That's all I wanted, so I am very pleased and consider this a fix.

Thats what I did when mine started shutting down at 15%. only difference was I also did a battery pull afterwards before switching on. It now shuts down on average just below 5%, varies though, ..sometimes it might go as low as 1 or 2%.

I consider this 15% shut off a bug that is common on the Desire.
 
i am going to post my story hopefully for someone's help

first try - calibration method with phone turned on without deleting the baterry stats at full charge
second try - calibration method with phone turned on with deleting the baterry stats at full charge

third and succesful try - charging the phone while turned off and deleting the baterry stats (but don't know if deleting them really helped)
now my phone is turning off at 2% and it was turning at 14-13%
